Don't see this hybrid set up very often. Lets get some pics going here!

Q.Smooth127

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.

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

SamsonS4

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

Heres mine.

Mine was somehow already posted in the original post, when it had the full-race manifold, but here are a couple of mine. Touge Factory is doing a killer job!

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

Imarvin240

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.

SamsonS4

nice value cover

Q.Smooth127

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

Imarvin240

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. :/

Imarvin240

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

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 !

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?

PerilousActs

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...

Imarvin240

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.

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?

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...

Yellow4g63

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

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.
