The Sr20/Sr22vet thread

[simmode1]

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.

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...

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



GT2868 on E85 rwd VE+T.
