Ok So i have narrowed it down to two turbos, which both have good response and produce some great figures in excess of 200rwkw.... Which would you choose?


Garrett GT2871R
Compressor inner diamater: 51.2mm Outer Diamater: 71.00mm 52 Trim A/R 0.60
Turbine wheel diamater 53.9mm Trim 76 and A/R 0.64

Turbo is Dual Ball Bearing water and Oil Cooled boost starts at roughly 2700rpm and is all in by 4000rpm

Turbo + Braided Lines + Gaskets + actuator = 1670.00


Tomei M7960

Compressor inner diamater: 52.6mm Outer Diamater: 68.00mm 60 Trim
Turbine wheel inner diamater 61.00mm Outer Diamater: 54.00mm 78 Trim

Turbo has Journal bearings is water and oil cooled, with maximum boost achieved by 4000rpm

TURBO complete kit = $1660.00

Im in a stalemate guys which do i choose!

dude went for a ride in a Spec R with one of these TOMEI M7960 kits, was making 240rwkw on a very, very rich conservative tune and OMFG!!!
Turbo was all ready to go by what looked like 3800-4000 and pulled like a god damn train until redline!!!
Injectors were close to maxing out aswell, hence the lower power level considering what the turbo can flow. A set of 260-264 cams and you'll really start making some serious grunt.
Spun tyres through most of 2rd gear and struggled to keep the car in a straight line in 3rd sometimes.
Everyone has a GT2871 or GTRS...go the tomei. It's ben tried and tested and made by Tomei, you cant go wrong. As for journal bearing, they are just as reliable as a ball bearing turbo, just keep up with the oil changes.

Im putting one of these kits on my S15. In the end both units will perform....im only choosing tomei because i want to break the GT2871 fellowship lol, eventhough the 2871r is a great bit of gear.

Have you gone in a ride with a 2871r? Curious for a hands on comparison cause I just ordered an M7960 over the 2871r from the US, pumped to get it in matched with a set of easy cams.

I have a friend with a GT2871R on his Spec S. Making 230rwkw though. Even though it went pretty damn hard...it was running higher boost than Ricks tomei turbo'd S15....he was running 19-20psi if i remember right and the GT2871R S15 was running 22psi i think..around there anyway. The tomei powered car felt a lot more than 10rwkw quicker...if that makes sense lol?
I reckon the guy said that the 2871R S15's tune was quite aggressive aswell....really should be making more then 230rwkw though!

If you want a bit more info check out http://www.nissansil...1

East coast customs has fitted a few of them and rates them above 2871r, altho I have read a couple of negative things on other forums, but theres always going to be a dud in the bunch

Didn't have any...just standard im pretty sure, didn't ask. Idle was smooth, like no cam lope at all, so im guessing stock.
His tuner mentioned though that cams would really wake the engine up!

Good man lol. Standard FPR and rail will be fine as long as your fuel pump is decent. As for injectors and cams, i don't imagine 550's would get you to that power level and if they did i reckon they would be close to maxxed out, not too sure though.
A set of 260-264 cams would be perfect, prob more towards 260's for a streeter and 264's for a track/weekender

Just buy some 740's, almost same price and safer to go lower duty cycle on larger injectors

Sard 850's are dirt cheap aswell, may be a little overkill though, 740's would be great.
If you have the cash, a Tomei expreme dump pipe would be killer!!!

go the 740's, safer to down tune the larger injectors then lean out smaller ones, and theyre the same price

Not too sure mate, sorry. Said the tune was quite rich and safe, so in that case obviously the injectors were big enough lol....bigger than 550's i'd say.
I'll find out for you.

at a guess I reckon 550's would max out at roughly 220-230 rwkw, may be wrong tho

I only want to go maximum of 230rwkw as my clutch is rated at 250rwkw that's why I'm thinking of going 555cc hmmm does anyone make 600cc?
