what turbo is good for me

[sx_hatch]

i have a red top sr20det with greddy fmic, greddy oil pan, koyo rad, spec 2 clutch, short shifter, profec b boost controler, i want to knoe what turbo is good for 375-400 whp im planing on geting 555nismo or 650 injectors i just orderd a wideband o2 and gauge and apexi safc neo for tuning but like i said i want a good turbo mines stock thanx for your help

[sx_hatch]

anyone

[sx_hatch]

no one can help

[leroiboy]

jump on the bandwagon and get gt2871r. .63 or 86a/r.

[sx_hatch]

if i had 555nismo injectors would those work with that turbo

safc wont work with over 555 cc injectors

[sx_hatch]

my friend is using a safc and he has 650s

[efrain240sx]

my friend is using a safc and he has 650s

only way 650's would work with a safc is if the ecu is tuned for them and you are just useing the safc to fine tune them. the safc 1,2&neo is only good for injectors up to 550cc

[sx_hatch]

at what psi would 555cc injectors be good till on a gt2871r

Your lack of searching is making me sick.

Check out my thread '400 hp 2871r .64' for help.

PS: Throw that SAFC in the brush. It's a pile of trash. Spend the money, get a ROM tune from JWT and be done/safe/boosting in no time.

[TchouikoS13]

when i get my gt28 imma get higher than 550, just for some leeway. Also listen to codyace

EDIT: btw, codyace, hows your setup been treating you so far. Any complaints?

[turbomrdeuce]

sx_hatch dont worry about it .63 is more streetable the .86 isnt as but just is rated to push more hp. I believe srdub-t has 720cc on his safc if im not mistaking. Heres something to help you out a bit with your whp goals and injector picks

This is a conservative rating at 3 bar. * indicate side feed inj sizes that can be bought from Nissan, Nismo or Tomei. Alot of the sizes you can not get but are there to help you if you are looking at a cetain flow rate by going to 4 bar.

3 BAR = 44 PSI, All the Nissans with Fuel Presure Regulators operate at 3 bar.

4 BAR = 59 PSI Running at 4 bar is better than running at 3 bar. Here is why, you can get more WHP from your inj at 4 bar, there is no xtra cost for a 4 bar program from JWT, you get better drivability at 4 bar because of better fuel atomization and you car will do better at the emmisions station becasue of better fuel atomization.

All Nissan Side feed injs are high impedence

The GTIR 444cc Inj is low impedence

91-99 USDM SR20DE = 259 cc side feed injs00-02 USDM SR20DE RR = top feed injs

U12, U13, W10 and W11 SR20DET = 370 cc Side Feed injsPulsar GTIR SR20DET = 444 cc Top Feed injs

Nissan Top Feed Injs

MSD Top Feed Injs

MSD Injs do not run right at 4 bar so don't try it.

Thank you Andreas Miko

Very useful post turbomrdeuce! Great! =)

Although my 50lb MSD Top Feeds (i do believe mine are 55lb though) are equivilant of 580cc or something like that. I just pulled a dyno on my .64 for 380 WHP with 18psi. I'm in Utah.

Also running 3 bar, roughly 44 psi at idle and 38 psi at full boost.

Absolutly love it. Power everywhere, never out of the turbo range....it drives like a damn v8 car

FWIW: It takes a 500+ whp Cobra/ws6 to run me down

You should really check you rfuel pressure! At idle you should be roughly 35/38 and in boost you should be 43.5 + whatever boost level you area running. If you're only making 38 psi in full boost, your car is certainly running lean up top (unsafe)

dude...get a wideband sensor with datalogging....a gauge is useless....there's no way you can watch the gauge while you're driving and tune anything at the same time.

here are a few i have been considering:

http://www.blacktrax.net/produ....html

http://www.innovatemotorsports...1.php

i think the smartest thing would be to copy a tried and true setup instead of insisting on being different. gt2871r with big enough injectors, basic power upgrades (fmic, exhaust, clutch), tuning and management, and ofcourse - the ability to drive effectively.

yeah i got a innovate it kicks ****ing ***

[Deadrodent]

really? which one?

[ZL-Auto]

GT2871r or GT3071r Company drift car runs a 2871R at 356rwhp @ 18lbs.

[turbomrdeuce]

really? which one?

i got the lm1 with the rpm reader

[codyace]

really? which one?

By no means is the Innovate LM1 crap, as it's fantastic...the downfall is that it's the size of a Gameboy one.

I personally prefer the PLX M300 wideband. Have used/installed them in 6 turbo cars (local to me) and can't ask for a better product. Reasonably priced, and you can use the little cassette tape sized unit, or use a 2 1/16 gauge for readout.

[Deadrodent]

does the PLX M300 wideband have any features the lm1 lacks? and while i'm thread jacking i might as well ask a question that has been burning a hole in my brain...

does anyone tune j4 ecu's for the type x blacktop?

the lm1 is great but yeah it is pretty fing big lol

Unsure. I think the main difference is datalog, but the M500 does that.

does anyone tune j4 ecu's for the type x blacktop?

ECU to motor doesn't mean much...it's more important that you keep the same color connector to the same engine. If the blacktop engine's ECU harness has a white connector, than any 2 litre OBDII Nissan ECU will work. If it's blue, any 2 ltr OBDI nissan ecu will work.

My car is actually running on a p10 G20 ecu from JWT.
