Rb25 Gt2876 15Psi At 4800?

[AngryRB]

My brother has one of these turbo's on his r33, and its nothing like whats been mentioned here

his runs only 11psi and is like an animal, it pulls from 3500 to 7000rpm, breaks traction in second too, im guessing it has a large rear housing

Although i dont know about its long term health, it suffers from some bad surging.

11psi from 3500rpm is hardly impressive, especially from a turbo which is probably going to hit a wall around 260kw. At such low boost it won't be at the turbos limit, so no wonder it doesn't fall over by 7000rpm - pulls hard is a relative term, 11psi isn't going to deliver what I consider to be "pulls hard" on a stock RB25. Surging at 11psi is particularly unimpressive, you've pretty much managed to make a ill-thought of turbo look even worse in my eyes with your post. My GT3076R pulled PROPER hard from 3500rpm (well, compared to 11psi on a GT28), without surge, on 17psi - many many a good time had with it.

To the OP, nice work - sounds like you're heading towards what is going to be a really really well sorted package... having the GT2876R sound like the only downside to it. Once thats binned, its going to be a proper all around weapon

lol, didnt mean to step on peoples toes with that comment

I wasnt meaning to make a comparison between a gt2876 and any gt30's,

For such low boost on this gt2876, its the most fun, aggressive car ive seen, ( not seen many gt30's yet)

If i can get a video of it, itwould paint a better picture.

I cant see how u can safely have we'll say 500hp for less than 7k. Once you introduce 500hp, you cause alot of problems elsewhere, clutch, suspension, brakes to name a few.

EDIT: no point have 1000hp if you cant turn or stop - especially for a road registered car.

Then to also get a turbo, fit and, tune it, run a fuel system, get it to flow and get it all plumbed up, I cant see it happening unless your getting amazing deals from suppliers.

regardless, I do understand that I have spent "more" than needed to reach this figure, but it is a fantastic starting point in terms of a drift car. Its pretty much what I asked for, and in my opinion, its what I got.

Not trolling or having a go at you or anything ok?

but you've only mentioned that you've spent $14k to achieve those power figures and nothing else in terms of suspension, bushing, brakes, etc..

I had a gt3076 with a 0.63 rear, water meth injection, making 315rwkw, and 720nm of torque.

Now that was an animal and pulled hard.

Fish tailed at 100kmph when put back to 3rd gear and the throttle rolled on.

Tyres were brand new 245 khumo KU31s.

This turbo is bad, time to stop flogging a dead horse, lol.

lol i think he gets it, the turbo is shit. hes planning to get a pretty nice one too so it all sounds good and the rest of the setup is well sorted for what he plans to do/

Johnny, for a workshop built setup 14k (parts price in mind) isnt too bad. Im sure hes spent a packet elsewhere. Its a freaking expensive hobby when you pay for NEW parts to be installed by SOMEONE ELSE lol.

OP, can you confirm is that a GT28 Tial rear housing or what? I didnt think they made those..

sure is, straight from tial.

very looking at getting the gtx3076 in the very near future (hopefully)...

Facts:

1)Generally the only time you hear about cropped GT30 based turbos being called GT28s is with the HKS GT2835s , who knows why they did this . My best guess is that they used some of these "GT2835" cartridges in GT28 turbine housings ie for SRs and RB26s . Some of these HKS spec units date back to the early 90's and in those days both TB25 and GT28 turbines were called "GT25xx" ie in GT2510 and GT2530 and GT2540 .

2)What you are calling a GT2876R comes with a GT28 NS111 turbine and a 48 trim 7/7 bladed T04S compressor wheel . It is not the same as the one HKS had in their spec "GT2540" turbos . The 2540 use the same GT28 turbine but its compressor was a 46 trim 6/6 bladed T04E wheel . Neither is really a gun combination but the Garrett marketed one truly is an exercise in stupidity - by Garrett that is . You have to wonder about a marketing dept that advertises turbos like this GT2876R and then tells you its not suitable for virtually anything .

RB20's seem to need something that spins up reasonably early but doesn't choke up too easily on the hot side . I did hear that Garrett may be tooling up to make twin scroll T3 flanged turbine housings for these new GTX2863R and GTX2867R turbos and if they have twin integral wastegates it sounds pretty good for RB20s or even 25s with 2871Rs .

With whats around now GTRSs sound like good things for RB20's . I'd think GT30 based turbos like GT and GTX3076Rs would be a bit laggy for and RB20 unless you ran big revs all the time .
