sr20vet or s14 tomei engine build

[jlmillionaire]

Hi all, i have some good questions about my future engine build,i really have my heart set on s14 with all tomei goodies.I want a high hp engine that will last for a long time.i can go in to specific parts but i will if someone asks on the thread.Now my question is ive heard good thing about the neo vvl head swap but what kind of block would i need?or how do would i build one ? and will it be better then the tomei built engine? and good for street and track occasional drifting if i get the chance just need some good pointers fro msome good people thanks.

[Sileighty_85]

You should search

If you want High Hp maybe look in to other engines other than the SR

[jlmillionaire]

i think about 500 hp is about what i want maybe 550

[jr_ss]

VVL will make more power any day of the week over a S14 SR.

[racepar1]

A 500 or 550 horsepower SR will likely not last for a long time. That's a lot of horsepower to be squeezing out of a 2.0l 4-cylinder. It also will likely not be very driveable, street wise. It'll be peaky with noticeable turbo lag at best, at worst it could be ridiculous turbo lag. The only swappable engines that you can really run reliably at that kind of power level are the GM LS engines. You might be able to run an RB as well, but cooling would be a major issue. You really need to re-focus your project goals a little if you want a reliable, driveable car...

[icedsole]

if your looking for that kind of power just buy a vvl long block from mazworks

[codyace]

5.3' are like, 400 bucks. Throw a cam in it, maybe some heads.

[jlmillionaire]

so what kind of hp can i expect from the vvl head on the sr block,and i just need the head and kit from mazworks?

[Om1kron]

hey guys, I'm paraplegic, please spoon feed me.

Doesn't matter if you have a new engine off of the assembly line built for 500hp and guaranteeing it for thousands of miles, shit happens. All of the tomei goodies in the world or a vvl mazworx engine isn't going to last a lifetime. Their drag s15 just popped an SR that was freshly build, mind you it's like 1000 hp or something ridiculous.

Research, build your own then ask how to hit your mark if you're stumped. Next you're going to ask which brands are better. everything is made in china so it don't matter.

[jlmillionaire]

yes i understand shit happens im just trying to figure out the better route in my future plans

[westky240]

500hp on a sr isnt too hard man.. it will last a little bit depending on who tunes it.. A tune is everything.. Also with 500hp your gonna have lag man. Your looking at lots of money.. Build the head and bottom end, twin schroll manifold, gt35r and you will be pushing close to 500hp.

[PoorMans180SX]

You're a millionaire right? Call up Mazworx and order an engine. Bam! That's as reliable as it gets.

[bb4_96]

^ I wasn't going to say it

[S14DOOD]

Just do a GM 5.3 with some different heads, slap a couple of ebay turbos on it and a tune. I was reading wb this in some mag they put down like 1200 hp on a stock engine with a good tune. They beat and beat on that damn thing and could not get it to blow.

[S14DOOD]

correction it was a GM 4.8

I think it's actually like 1600hp... Just sayin

Why bother staying efi. Just go blow through carb and all your tuning is mechanical and at the track without a laptop. Simplify's things even more, lol.

Hmmm, 1000 dollar blow through carb that still needs to be adjusted
or

Factory PCM and HP tuners for 500 bucks that works great

SR is the last motor you wanna be looking at for a streetable 500whp car. Quick question though, have you ever been in a vehicle with 500whp 4cyl? if so why the hell would you want to drive one around, that's pure track in my book

[S14DOOD]

yea this would be a wast of money in my opnion.

[!Zar!]

And the question that hasn't been asked yet, 'why?'.

[Def]

5.3' are like, 400 bucks. Throw a cam in it, maybe some heads.

500 bhp maybe, 500 rwhp? I guess it could happen if you had A LOT of supporting mods, but that's near 100 rwhp/L. GM LS engines are good, but not that good.

The thing is not going to live a happy life if it has to continually rev around the 7.5k RPM redline it'd need to make that power.

It is an easy way up to 380 rwhp tho'.

[jlmillionaire]

so vvl is the way to go with a built block what do i need for the build? or should i just build the sr with good mods

[T chop]

LS7, reliable and probably cheaper than a 500WHP SR build.

[bb4_96]

Are LSX posts considered theadjacking?

OP VVL is going to be research intensive. Either do some or pay a shop to. I've seen some decent writeups around the web.

MY friend had a 500hp daily driven Evo8 with no problems at all, It did fine in every way possible. Don't knock something until you have owned it

I also have a sti as well looking do like 6 and change but it has about 90 k ill prob blow it up lol

Yeah, I don't think I'd be dumping that amount of money in the EJ... They'll make good power, but def not good canidates for high hp... If you haven't already blown number 4 ring lands, it'll only be a matter of time.

[jlmillionaire]

yes i heard the head of the ej is built for that kind of hp but bottom end can withstand 500hp

stock block sr20, stock vvl head, mazworx vvl kit, Z32 transmission, supporting clutch, gt30R turbo, good tune = reliable 500whp for street or track

It is that easy people.

PS for all the V8 propping people. The 4 banger is much more fun.

Your car runs super well, and I love SR20.

But a pretty basic LS based setup would work just as well.

ok sounds like the direction i want to go,ive been looking for write ups on what excactaly i need for the build can someone help me out

[jlmillionaire]

so who has the write up on how to do the vvl conversion

[PoorMans180SX]

There aren't many full write-ups. Pieces of information floating around people's build threads and whatnot, so you'll have to do some searching. It's not too bad.

ya i agree with him 4 bangers are way more fun than taking the easy way out on what you want. nothing wrong with v8s they make great power but there just not ment for something as of the s chassis

there is no problem with a 500+ hp SR dude. i have had 2 500+ hp SR 240s so far that i daily drove no problem and im in the middle of making my 700-800hp SR22VET car...and i will drive it on the road as much as i can. i do have a winter/rain car but i am not keeping my money pit bound to the track. an SR is fine with 500 hp if the build it done properly, it is maintained correctly, and you have the right supporting mods (I.E. suspension, brakes, wheels, ect.) there are tons of people on this forum that have/had a 500+ SR setup...and im sure alot of them daily drove there cars. just because you may not be able to handle a 500+hp car, doesnt mean the OP cant. with that said, OP, good luck with the build and i would go VE head.

[Drftr915]

No offense man, but quit being lazy. No one is going to have all the answers to your questions on here, and everyone has a different preference, or perspective. If you want to know about the vvl head swap i would talk mazworx, search, and read.

your rite lol im gonna call them tmw

[Driftingcorners]

omg why have you guys not suggested it...

2jz, GT35XR(NEW GARRETT), FUEL OR NO FUEL DOESNT MATTER, STOCK FUEL IS GOOD TILL 500, AEM EMS V2, NO LAG. 500hp all day, every day.

[Imarvin240]

why is the pump gas only good to 500hp? i know people with supras and 2jz swaps running much more then 500hp with 93 octane fuel. its more psi and compression ratio that determines the fuel not horse power.

[jlmillionaire]

to do the 2jz swap is probably very complicated,and what about the wiring harness and such??i like the idea of the mazworx vvl build imarvin holla at me give me some pointers and how much was it to build the sr22vet?

[shiftdrift]

A stock 2j swap is easier than a built vet build......lol. you need to research cost a bit buddy. Ls1, 2jz. Both will make 500 easy and reliable. Cheaper than. 2.2 stroker vet

[VATOCLOWN]

what about a vq35de turbo with like 10-12 pounds of boost you can get close to 500 and you can find them for cheap every so often. im just not a fan of throwing a non nissan motor in a nissan.

just sent you an extremely long message hah enjoy.

Also, to do a ve head on an sr to only hold 500hp isnt as expensive as you would think when comparing it to a 2jz, rb, vq, ls swap. for those other swaps, you make up the difference in cost by having to buy motor/transmission mount setups, drive shafts, converting wire harnesses, coolant hoses, possibly different radiator, modify exhaust (2jz/ls/vq), and so on. for the ve head, besides the cost of the engine setup itself, its minor wireing and the conversion package which mazworx has. argue all you want, the costs end up not being to far off from eachother. at that point, its just preference...and he wants to stay SR.

[whitey240]

Your car runs super well, and I love SR20.

But a pretty basic LS based setup would work just as well.


As my mom says, there is never a 'right' way to bake a cake.

I actually sold all my SR stuff this past winter and put a LS1 in the car. It is great and all but I would have much rather had the SR in it then LS.

Looking back at it all, I had about 8k into my SR setup and it netted me a very reliable 500hp car that had 0 issues. I put about 8K into the LS1 setup and I have heat issues, and fitment issues, and pain in the ass wiring to make everything work. As far as levels of difficulty the LS was definitely up there.

If I would do it all over again I would do these options in order.

1. SR20DET Block, VE Head, 30R Turbo, twin plate clutch, z32 tranny, hydraulic release bearing
2. LS1 Drop Out, LS6 Intake, builders choice on heads and cam, spray
3. 2JZ, GT42R, AEM Engine Mgmt

Regardless of your choice... Good luck!

[jlmillionaire]

Ok vvl it is for my future build,I only can find p11 heads for sale! and i should be fine with a stock block for dd? or am i wasting my time and just get the bottom end done as well

[Yellow4g63]

buy a complete p11 sr20ve take what u need sell the rest to a fwd guy.

[Imarvin240]

Ok vvl it is for my future build,I only can find p11 heads for sale! and i should be fine with a stock block for dd? or am i wasting my time and just get the bottom end done as well

do the bottom end. you may run into clearence issues with the OEM pistons/rods since you have greater lift with the VE head. i have 90mm CP piston that were made for the VE (they have valve reliefs) you wont need 90mm though hah....buuuttt its always better to be safe then sorry.

[tdiazsch]

build a 2j or a ls. dont mess with a lil boy sr20

[Yellow4g63]

Hell yeah all the kool kids are doing it.

[whitey240]

If you are just looking for ~500 to the wheels stock bottom end will do you just fine. Besides... they are cheap!

[Imarvin240]

build a 2j or a ls. dont mess with a lil boy sr20

not to call you out, but what do you have that you are calling it a lil boy sr20? are you calling it a lil boy sr20 because its a 4 cylinder or because "you" think it can't make alot of power? FYI, my sr will be making ~750 safely. its built to handle much more than that, the limiting factor is the turbo setup that i chose. an sr has no trouble keeping up and in some cases, beating up on the big boy engines. anyone that has had a well built sr can attest to that.

and to "build" a 2jz or "build" an ls and say its cheaper then an sr, is insane. parts for an ls engine may be a bit cheaper due to it being domestic and more common, but you are buying parts for 8 cylinders...that adds up quick. and to build a 2jz again the price adds up. you guys make no sence when you say that an sr isn't a good engine. all your other ideas require tons of additional parts like driveshafts, custom wireharness, motor/trans mounts, ect... those will bring up the price to the cost or above the cost of a 500hp sr. sorry for the rant, but i think it was needed hah
