So I have decided I want some more power out of my SR20.

1. How much power will stock internals hold reliabley?
2. If I was to get a GT2871R 0.64, what would a safe boost be to run at?
3. Should I upgrade my 370CC injectors to 555CCs?
4. Should I consider a full build, and at what price?
5. Any other things I should consider?

1-around 350-450
2-15 at low 18 at high
3-Yes.
4- not really, just get some poncam with 256 lift on both sides.
5- of course, u wanna go fast but how r u gonna handle around the corners.

gt2871r, z32 maf, 660cc or bigger injectors,power fc, 17 pounds of boost, stock internals and typical bolt on sr20 upgrades will get you up near or a bit over 350whp.

like ottamania said though if you want to go fast make sure you have the footworks to handle it safely. Coilovers are a must

Plans are:

ISIS Downpipe
ISIS Test Pipe
GT2871R Kit
555CC Injectors
ISIS Intake Manifold Kit
S14 Throttle Pulley Wheel
Cometic 1.01mm Head Gasket

And I already have other parts installed. Brake upgrades are in the near future as well.

Just need to test my compression first.

Do you think I should look at a upgraded waterpump?

I ran 14psi on my 2871 last year and it held up just fine.

injectors are a must and you can get away without the power fc. but it is recomended.

for the cost of a full build it is not worth it. in this stage of your car. Whenver the SR blows up is when I would do a build.

thats what I did. on a poor tune I still do high 12s in the 1/4.


yeah without some decent suspension you wont be able to handle that power as well as you could. thats my next step in my build.

I remeber running against your 240 this year. Popped a vacuum line lol, I was going into the race knowing I had no chance, but mechanical failure helped me out!

I already have a decent suspension set up, and im going to be doing minor brake uprades soon too. Had no problems on the road course this year.

Already have a 255LPH pump, AFC, FPR, FMIC, Boost Controller, Cat-Back, Intake etc, so I have a decent base to start from. I need to do a compression test first though, hopefully its got decent compression still.

bawlls
lower boost = more reliable

Im shooting for 12psi, just gonna try to squeeze power out of other things like headers

RZRSHARP_SVX
yeah I have since solved that problem. but my transmision is messed up now.

Nissan_Fanboy

headers ?
haha
Intake and Exhaust Manifold !!!

but yeah 12psi sounds decent for a reliable and safe amount of power.

Personally i would run around there and just turn it up a little if i wanted to rip it on the track or something.

/fixed. is 350WHP on a SR really that hard?

better have went with a 2.4L+



... i kidd i kidd.

I would honestly rather have a built KA24 than an SR20, but ive already got an SR...
