you must have been living under a rock.
cause the VE head swap has been around for YEARS.
When goin for big power, If people arent doing the o so typical LSx swapped 240, its goin for the rev happy VE head swap onto the SR RWD block. (that is if they dont elect for a 2jz or RB swap). The only reason LSx is just so popular is cause any guy in the US can just find a LS longblock in a junkyard haha. And since its a domestic, LOTS of easy parts and aftermarket parts.

I personally like the VE head swaps (no more rocker arm issues) over the other stuff just to show a 4 banger can hang wit the bigger cylinder fellas haha. If i ever got a better payin job id do a VE head swap as well lol.

Ugh. I guess there is no "official" VE thread on here but they're are quite a few build threads covering this topic. I'm in the middle of my engine build right now.

Here is mine !

Double post

Nobody said it was new. Just isnt exactly common. Here and there yes on a webforum but not common.

I'd have to say the BFE motorsports SR22VET set up is butt ugly tho. That intake manifold is just really ugly looking.

Is there a few definitive VE engine threads that you guys would recommend for the fundamentals?

There are a number of good build threads that are doing VE engines, that are definitely worth taking a look at. They offer a range of different parts, styles, purposes, and budgets. I'm sure I missed a few, but here are the threads I could think of.

Mine is still in pieces. :/ Yes that's a P12 head.
http://i35.photobucket.com/albums/d2...12AB48241A.jpg

nice value cover

yup. Dat p12 valve covers are Le Sex.

imarvin i see you got tomei solid lifters on that VE head swap. I thought the sole purpose wit doin the VE head swap was for no longer needing to worry about rocker arm issues and the obvious fact that VE heads flow even more better. So without those rocker issues, cant you rev the shit outta of those VE heads already even wit their stock lifters?
Or are they just to make it further boss haha?

thanks for all the nice links to the builds guys.
got me some nice reading material as i eat this sammwichhh

Nah, that was a typo on my part (my DE engine has tomei solid lifters, not my VE engine). But yes, you can rev the the life out of a VE head.

It isn't just the valve cover. lmao Look at the intake ports, you'll see it isn't a P11 head. Does anyone know where I can get valve springs for a P12 head? They are completely different. :/

I would talk to Mazworx or Raw Brokerage. I'm pretty sure Mazworx uses a P12 head on their drag S15.

P12 valve springs are pretty hard to come by. I know a guy had some made but I think he sold all 12 sets he had made. You can add the inner spring from the P11 into the stock P12 spring to help.

As far as OEM springs, the P12 single springs are actually stiffer than the P11 dual setup, if I recall correctly.
It is also possible to convert to the P11 dual setup, as long as one uses the all the valve parts from the P11 head.
I am in the middle of installing springs and retainers in my VE right now. :)

I dread the day when the 20V plug cover will get scratched. Does anyone know a color match for the red lettering?

Where is everyone sourcing their P12 heads at? I've seen very few places with them.

Thanks for starting this thread. I keep seeing ppl mention VET builds, but I never knew where to start looking for info. Now I got some reading to do!Forgive my ignorance, guys... But I just wiki'd the SR20VET to compare it to the DET and I have a question:Wiki rated the VET at 276hp using the GT2560rs... Is that the same turbo we commomly refer to as the shitty little T25 with the 14psi limit?! If so, at what stock psi does that motor run to achieve that 276hp? I'm guessing a VET setup with an S15 GT2860RS is how all the JDM tuners in the Hot Version videos are hitting like claims of 380hp for what they call 'fairly cheap while using OEM parts'. I always thought they were bullshitting...

Talk to Mazworx or Raw Brokerage. Those would probably be your best bet.

Nah, that's a different turbo then the factory S13 sr20det turbo. Besides that, doing a VE conversion isn't really a fairly cheap way to make power. Just the items to do the conversion will cost you thousands. The same amount of money into a det engine will more then likely get you 380hp+, but standard det engine will never be as strong or capable of making more power then the VE head. The VE head offers TONS of benifits (larger ports, larger valves, roller rockers, variable valve lift and timing, ect.), with only one negative...cost. Basically, the VE head is the best choice, if you have the money/time.

Im pretty sure mazworx use a p11

Stock for stock p12 flow better but p11 have more potential when ported (that was from an othee thread !

Most available aftermarket performance parts are only available for the P11 heads. The P12 heads uses different valve springs, retainers, guides, seals, valves etc. The exhaust ports are exactly the same on both P11 and P12 vs the intake is slightly different in port dimensions and bolt on locations.

The main difference that would make the P12 head "flow" better is that it uses a smaller diameter valve stem 5.5mm vs most SR's that use 6mm.

ive always wanted to do this but get psyched out when I read whats involved in doing it.

Here is mine, getting there slowly!

http://i60.photobucket.com/albums/h2...9.jpg~original

Cant wait to see result with the new hypertune bottom mount manifold

Even Under Suzuki will run it on is s15

Subscribing. I may look into this more in the future.

Quick question though... Do you need a S14 or S13 RWD block? Or, does it matter? I have a stroker s13 block that I have not been able to sell, so I was thinking about using it for this swap one day, but didn't know if it would work.

I didnt know you were on the forum !?! I know someone that upgraded to 6mm stem on is p12 and use p11 valve spring by machining the spring seat

Give a look to autotech motoring guys , they make killer parts for our engines !

http://i202.photobucket.com/albums/a...t/image-45.jpg

Ditto. I got amped up when I just now learned about it. I thought I knew just about everything you could do to an SR and was excited to learn something new. But it looks like way more work & money than I'd need to spend for my meager goals. I'd be interested in doing the VET swap & pairing it with a S15 turbo. But it sounds like this is waaaay too cost prohibitive to handcuff it with an S15 snail. Guess I got kinda excited to find out how the few S-Chassis on Hot Version videos probably achieved their level of performance on OEM components. I think I'll just stick with the typical GT2871r or EFR6258 build unless I start balling out like the rest of you guys doing this swap.

I have a s14 block for my ve conversion ! Lets just say its easier with a s13

I had to plug my vtc oil feed at the front of the engine ! And drill a hole in the front of the block for my oil pump cassing bolt !!!

You still need to plug the rear drain hole because its not covered completly on s13 / s14 / s15 engine

My buddy Dave Briggs runs vvl killer cam on is sr24vet

Most of my built idea is from looking at this motor

I then looked at the motoiq built (sr15vet land speed record) and i saw that i didnt do what those guys did !

With the vvl killer mod you dont use oil pressure to switch from low to high lobe ! And i guess with no oil going to that vvl relocation kit in the back you dont have to plug that port under the head !

http://i202.photobucket.com/albums/a...t/image-47.jpg

My question can i plug it of from the back (by removing the vvl relocation and pluging the port because everything is instaled on my engine

whoaaaaaaaaaaaaaaaaaaa


neo

They have a OEM SR20VET that is AWD, It only uses VVL on the intake cam. The Exhaust cam doesn't kick like the non turbo SR20VE P11 and P12 SR20VE. The SR20VET head is the same as the SR20VE P12 head you just need exhaust rockers from a N/A VE to make the conversion. The cams are also milder on the SR20VET. Confused yet lol?

What exactly is the point of running a ve head with gigantic cams without using the VVL? lol Car will be a complete slug down low.

Eliminating the VVL will be mainly used for non-street cars. VVL requires oil pressure for activation and by eliminating it generally increases oil pressure. It also lightnens up the valvetrain slightly. Most race cars are operating at higher rpm ranges anyways so the more aggressive main cam lobs are being used at all times.

This is a sr24vet with the vvl killer mod

+ to have intake port way bigger vs a det engine will help too

Yes. Thoroughly. So you use the OEM N/A VE cams and exhaust rockers in the VET head so that you'll have VVL on both the intake & exhaust side? I'm still trying to determine if this is worth my time & effort since I have pretty mild goals. I need to see some video or dyno breakdowns to see what are the real world merits of this. Like, if someone did what you described above & used a stock DET turbo like a T25 or T28, what would the gains be? What would this VET conversion yield with a GT2871r or EFR 6258 versus a DET head? Trying to compare & contrast...

I'll post the dyno later, but back when these swaps weren't main stream, there was a guy with a blue hatch that had a DET making just under 400whp on a GT3076R. Mazworx did the VET conversion for him. With just the head swap and other necessary components( intake manifold, injectors, throttle body, tune) he made 491whp at 18-19psi. This was with the same stock bottomend and exhaust components. So in other words, the swap gave him almost 100hp. Obviously you aren't going to see results like that with a t25/28 but better/higher flowing turbos will compliment this head much better. If you're looking for high hp or a very responsive 450hp, this is what you want/need. The DET flows like shit plain and simple.

^^^Ooo wee... Thats the kind of testimonials I'm looking for. Thanks.

So let me ask: VET head with VE cams/exhaust rockers on stock DET block bolted up with an S15 GT2860r @ 14psi... 350whp sound realistic? Waste of time? What other factors should I consider?

Easiest thing would be to get the P11 SR20VE head. way more of them around than the 20V and VET head.

You could try messing around with the stock X-Trail turbo. It can still be bought new from around the world for pretty cheap. :)

http://www.floridasr20s.com/gallery/...4/DSC04233.jpg

I'm no expect but why not go a larger turbo then s15 if you are going to do the VE swap? VE gives great response so even if you go larger it's not as laggy as a det head?

Personally, I have not driven in an S-Chassis with more than 300whp. I'm a little hesitant to step up to the 450hp level because I worry about driveability & lack of traction on the street at that point. I think 350hp is more than enough to have fun with and get me into trouble. I'll probably just stick with a turbo upgrade on the DET head. VET seems like the SR big leagues and I'm just a small fry. I try to be realistic about my limits.

Realistically you can but with virtually any turbo setup you use with the VE head will out gain anything you try and do with a DET head. The VE head stock outflows any ported/worked DET head. The increase in intake port size, combustion chamber design and factory head characteristics will help the turbo work alot more efficiently and lower/mid rpm range.

The only downfall in the stock VE head is the exhaust guides and valves and the head was not made for extreme heat from a turbo setup. The VET 20V head is a good option but you are not going to find a cylinder head setup by itself rarely and the full longblocks are still going in the 2K range vs you can by a complete VE P11 longblock for around 800

I'm not good with turbo sizing but how would a vet set up act with a gtr-s set up? I had one on my old set up w/ s14 SR20DET and netted 350HP

A GTR-S will be way to small for a VET head conversion, they're not even that great on a normal DET head.

I wish there was a definitive how to thread for what is involved in one of these swaps.

^ serious..?

1. P11 or P12 head
2. VVL relocation plates if you have a p11 head. (solenoid is larger)
3. Sr20ve oil pump
4. Pistons with valve reliefs if you plan on running anything larger than p11 cams
5. 20V cas (won't clear s14 lhd firewall)
6. Hall sensor kit if you opt not to use 20v cas
7. fwd sr20de or any other aftermarket sr20 cam gears.
8. sr20ve oil pump drive gear or mazworx spacer
9. machined stock pulley
10. plug oil drain port on block
11. plug oil drain port on head
12. Drill and tap oil feed for vvl solenoid. (side of head)
13. Oil feed line to vvl
14. Oval bolt holes on sr20det manifold of choice or build one with ve flange
15. Mazworx oil pickup tube
16. Mazworx or taarks water pipe
17. aem / denso pencil coils for p11 or s15 coil packs for p12 head
18. Head gasket of choice
19. Cut / flip stock upper intake manifold or xcessive, hypertune, mazworx plenum (xcessive / hypertune are the only options right now for p12 heads)

Pretty sure that's about it.

This is Hypertunes new 347 stainless manifold. One of the better VE manifolds going around! :)

Ok so i talked to the guys at mazworx ! There vvl relocation covers that oil port and we dont need to plug from under the head it like the guys did at motoIQ on there p12 !!!

**** this is with a mazworx plate i dont know if its the same with taarks , autotech motoring , xcessive , ......

If i didnt all ready had a DOC Race manifold that is prety awesome !! I would go with that hypertune low mount manifold


Electric power steering ???

Almost done with my engine ! Waiting on my bellhousing to come back from the machinist !!!!

http://i202.photobucket.com/albums/a...t/image-48.jpg

read some guy was why do a 2.2 if it lowered your rpm range if the whole idea of vet is for high revving

2.2 by bore (90mm) will not affect the rev ! A stroker kit can restrict abot more

We still get in the 8500 to 9000 with our 2.4

Found this floating around the web, S14/S15 lowport manifold with a chopped/welded VE flange.

pretty cool but the hyper tune manifold is best!

http://www.brewedmotorsports.com/ass...ottle_body.jpg

Shame the intake runners are so short, I was really considering hacking up a S14 manifold for use on a VE.

i posted the wrong one.

http://img.photobucket.com/albums/v4...36922448_n.jpg

This is a great list, but how come no one talks about ecu choices??

If you are using a 20v CAS, can you not use the stock ecu the sr20ve came with and get it rom tuned?? I personally prefer not to run standalones b/c of price and mainly b/c there are no good tuners here in town. They all want to make max power and can't setup a reliable tune

Also, this is great! S14 intake manifold bolts right up to this it looks like

http://www.nissansilvia.com/forums/i...tach_id=401137

That's a custom billet job. The VVL intake ports are bigger than the S14's.

2500$ us for an intake / throttle body and fuel rail is way to much for my budget !!!! If i could i would dont worry

what's another 2500 when vet setup is already a big baller set up:l101:

All fun and games aside as you are already aware of to build a proper vet setup is some big money and down time.

Def not a set up if budget minded is your game but no expense spared maximum power and response is your game. I read about in aussie land there was a event there was a rb28 tomei powered car and a sr22vet s15 going at it and the vet set up out performed the r28. Very impresive.

Yeah, I think that's why I probably won't do this. I love everything I've read about the VET swap, but ontop of the cost of doing it, I feel like you'd also need to totally revise your drivetrain & suspension to put all this power/response to the ground, even further increasing costs. Definitely not the route to go for someone like me looking for a simple & mild low 300hp range 240. VET is big boy stuff. But if I hit that point when 300hp+ is no longer enough for me... VET, here I come.

You can upgrade to vet for reliability too !

I started from scratch with this sr20vet

Sold my racecar that had a ls1 with g-force gsr too buy my house and stsrted this project on the side

A 400 to 500whp sr wont need all that much $$$

PJ's (fastest s13 with a h-patern transmission and street legal tire) makes 900whp with an xcessive intake that cost 300$ compare too all the other option that are close to 1000$ and up !!!


My friend has 425 whp

sr20vet:
Precision 5830
Topmount manifold
Stock head + dual valve springs upgrade
S15 transmission with exedy super single
Nothing to special


And he drives the car every day to work (he will upgrade the transmission when it brakes)

Personnaly I would not built a vet to run a t28 and have 300whp

almost done.....
https://scontent-a-sjc.xx.fbcdn.net/...43763908_n.jpg

I notice that everyone talks about the parts needed to make the conversion to reality, but what do everyone use as the engine harness?

Is there anyone other plugs on the wiring harness to run the head which is different if at all different from the SR20? Will the standalone PFC work with the head?

To make the VVL work, will a multi-switch need to be installed to turn it on or off?

I've been making decisions for the last year and half if I should go this route if I'm not hitting my goals just with my SR. I'm looking at what would work to make to a reality if I don't have to much to work with.

What are the options for this?

You can use your S13 harness for all the necessary sensors. You'll need to run an RPM switch to control the solenoids.

As for EMS, Nistune or ROM tuning can be utilized.

im doing a completely custom harness, but the majority of the harness is unchanged when switching to this head, you just need to modify it to accept the different coils and ignition box.

Existing engine harness stays the same. A tuneable ecu is a plus. You can use a MSD 8969 to activate the VVL and just wire in the solenoids to the unit.

Another plus that alot have not mentioned is that the VVL head uses solid shaft mounted rockers vs. free floating rockers in the std DET head. The chances of breaking rockers with the VVL head is 0 to none.

The sr20ve stock ecu plugs into S13 redtop/blacktop ecu plug?

No, you use the DET ECU with a ROM tune or Nistune...

You'll be running the DET harness and ECU, but have it tuned for your setup.

S13 ecu run the Nismotonic daughter board. It will kick the VVL for you if you use one of the outputs on the board and run a map sensor and 20X20 tables.

Decided to mock up the head and manifold on the block for some extra motivation. Been a slow build since I am paying for this semester of college at the moment.
http://i144.photobucket.com/albums/r...s98326f65.jpeg

Thanks for your help!

All of a sudden it doesn't look that complicated anymore. lol

p11 head, here I come.

Nope it honestly isnt. Other than wiring in the new Denso or equivalent coils and your VVL solenoids, its pretty much a straight forward swap over.

For the turbo manifold or exhaust manifold, would you have to notch the existing bolt holes to accomodate with the VET head? Does the exhaust ports match with the DET turbo manifolds?

Reason for the turbo manifold is because I don't want to buy another manifold since I am using the PowerLab twin scroll.

Exhaust ports share the same centerlines, you just need to lift the manifold up roughly .125". So oblonging the holes is a must if you have a DET manifold. The ports are higher in the head because of the coolant passages and different chamber and valve angles.

Or there are several manifold options out there already that can accomodate both DET and VE setups

He doesn't want to purchase a new manifold.

You should really need to spend much on manifolds or relocation blocks to convert to VVL if your not planning to go on monster build. I'm actually doing this now and I will share it with Zilvia on the Builds thread. Just waiting for Admin approval.
