Best way to get to around 400 hp on a sr20
I just got a s14 with a sr20 blacktop in it. Im trying to get around 400 hp out of it. What parts would be needed to produce somewhere around 400 hp? Any help on this would be great.

I really hate to say it but "search." It has been covered sooo many times. This is not the slightest special of a question that needs to be asked. You will find alot of info on this forum.

I have most of the things he said. All except 300zx maf and cams and nistune.I think the car has a jwt tuned ecu in it. If im shooting for 400 hp. What size injectors should i use and should i get Greddy E Manage or no?

dude, keep the jwt ecu and just have jwt retune it if I had to choose between jwt and emanage. don't go emanage, imo. info for 2871 setup, click: http://zilvia.net/f/tech-talk/124925...-sr-motor.html ...there's more to getting 400whp. You probably want it to last too. cooling, efficiently putting the hp down, reliability, etc...seriously, read around the forum.

Some people have been able to pull off 400whp on the dot with the smaller varient but it is more the exception than the rule. I suggest looking into the 50 Trim T04E compressor wheel with a T3 turbine housing, these turbos are extremely affordable if you don't mind going with a simple top mount manifold setup. The other suggestion I have is the GT3071R or GT3076R bottom mount varient, we have tuned a few up to 430-450 whp!!! on Stock bottom end and on a dyno dynamics (hear breaker dyno). Just some other things to keep i mind. Most important of all is TUNING TUNING TUNING. Whether is be local tuner, or high quality wideband to fine tune the fuel map, and getting a solid timing map from a map builder, or doing some serious dyno time with a tuner who knows his EFI. Tuning makes all the difference in longevity, low end power and power band curve and peak power.

Ignore the search comments!
Threads like this are necessary everyonce in a while, since newer parts come out people discover new setups, etc I would say get a gt30 or bigger size turbo to guarantee the 400hp mark Add cams 850cc injectors Good quality manifold 3" exhaust Fmic Q45 throttle body Z32 maf, To keep it simple i would say get a jwt tuned ecu and enjoy it! You can also get cams from jwt, they are awesome I would highly recommend getting forged piston/rod combo and ras You will Also Need a 6puck clutch or if you can afford it a twin plate would be best Sent from my iPhone using Tapatalk

sell sr20 make about 2 grand profit, save 4000 more dollars install proper ls1 with t56 transmission. never worry about dying turbos and always have 400hp on tap daily drivable and no cops giving you tickets for adjustable blow off valves.
bish bosh boosh.

Also you could buy someones setup Who Already has 400-500 hp built motor, ive seen a fee in the $4000-5000 mark Which isnt a bad price, either way you go you will end up spending way more if you build it up yourself from scratch. Sent from my iPhone using Tapatalk

I appreciate all the info. All of the info is very helpful to me. I would like to do a Ls1 but i already have the SR Blacktop with a good start on it being built. I have most of the things everyone has mention. Really all im lacking is a bigger turbo,bigger injectors,Z32 maf,and a wideband and a good tune to reach the numbers im looking for from what i see so far.See i have not even drove the car yet. Its getting a make over on the outside. Everything else is already in or on the motor. I have a good question. It has a aftermarket manifold on it. I think there is a Garrett GT28 turbo on it.Can I upgrade just the turbo to a bigger one and will it bolt directly on or will i have to change some things also with the turbo.Its a bottom mount set up.

Anyways to the OP, get a big turbo and some 1000cc injectors.. you'll make 400whp no problem with room for more if wanted.. and don't get steve shadows to tune your car lol.. |
