I want 550-600hp on my 96 r33 gtst which currently running on stock internal, turbo and aftermarket intercooler, 3"full exhaust, excedy hd clutch, bov, hks boost controller on 98 making 300hp.

Little bit confusion in buying turbo, wat should i go with gtx3576r gen 2 or gtx3582r with wat housing for street purpose and which one spool faster making stututu sound . I'm new to rb world and wat mods exactly i want to achieve that power on 98.

How are you defining those power levels? Engine, Dyno Dynamics roller, Mustang roller, hub dyno?

And naturally the 76R will spool faster. Smaller compressor wheel has less inertia.

There is a whole thread stickied at the top with many many results and dyno sheets for the turbos you ask about. Have a look.

man  honestly if your looking to make 600hp and you don't know the difference between those 2 turbos and haven't already read the 1000 posts on google about single swap setups I would just keep running the car stock.  bigger a/r flows more air but has more lag. don't over think it. pick a turbo make sure you have the fuel, a good ignition system and just send it mate. read lots!!!!!

You want to make 600hp on a stock internal rb25 on 98? 

This is going to be interesting.

Read carefully, i said it running on stock internal and i had much sense it's not possible on stock internal . Mostly my concern abt choosing a right turbo with not big housing ,i already gone through heaps of thread still struggling can't find anybody using gtx gen2 on rb25 with 600hp. Rest of mods i know very well.

It's not engine swap , i already gone through 100 threads but my concern is if i choose gtx3582r with.82 housing does it lag cause i read gtx3576r gen2 spool more faster and cause no lag at mid range with same housing.

There will be lag with either, it's not the difference between having a laggy set up and a response master.

 

So u mean i should go with .63housing then turbo doesn't matter

There is no point in choking a large compressor with a small exhaust housing. The smart approach to wanting good response is to choose a smaller turbo. the smart approach to wanting max power from a given compressor is to choose the smallest exhaust housing that will get you there - which is NOT the smallest housing available, generally.

well put. and even at 450whp is still gunna snap your neck m8, I would personally go with a  gt3076 or something along those lines. with a higher boost around 22psi. will achieve an easy 450whp with what I think would be a much better drivable power band and funner car in the end.

he can also look into water meth injection kits if he wants to run large boost on what ever turbo he decides. that's what I have setup on my car works great and keeps valves clean etc!

      My BMW 335i

      By PranK · Posted

      Ok, so we've had some (expensive) problems but nothing critical, thankfully. I get parts from FCP Euro in the states and in this instance I got 4 x genuine BMW cooling lines and 4 x OE quality oil lines (because they had no genuine stock). Well, turns out the OE quality didn't fit and the guys wasted a lot of time with them. Thankfully FCP has lifetime returns but the genuine BMW lines locally were $250 each! They also discovered my drivers side engine mount was totally dead and the replacement mount was $350. This sucks as I almost bought new mounts when I did my FCP order and I would have had both the engine mounts for less than this local one. So, I'm assuming at least another $1500 on top of the existing number. They did reassure me that the new (used) turbos looked good which was my main worry. Car will be ready for Monday pickup.

      Forgot to add, that excellent economy was on street tyres, normal street alignment, I recall they were Kumho KU31. Current motor, with the silly alignment and tyres would go nowhere near those numbers.

      And also, as small as the effect may be, the larger exhaust side places a lower restriction on the exhaust flow, even when off boost. When my bigger turbo went on you could hear the difference in the exhaust note at cruise (almost everywhere actually) and fuel consumption went down a little bit.

      I got better economy after fitting a bigger turbo (when purely highway driving, Sydney to Forster, got down to ~8.3L/100KM), as it takes more throttle and RPM to get on boost.

      Best bolt-on twins for RB26, ~300kw?

      Oops. Sorry mate. It is both excellent to hear and also surprising though. The amount of work required to (effectively manually, not on a production line) build a core vs your low retail price point is why I presumed that you were buying cores. But let's also be clear about what is meant by "build". At your price point I can't see you making cores from billet on a mill, even if CNC, or doing all the machine work on a rough casting. Surely the lumps of metal are sourced more or less ready to go from an Asian supplier, right? Maybe the same with shafts. I mean, you could turn shafts up yourself, but it's pretty slow going for items that are all essentially bulk order producable. I was always perfectly willing to believe that you assemble your wheels to shafts, fit up bearings and do all the balancing. I actually expected that you would have been doing all that even if the core did arrive from a supplier with most of that pre-assembled. Nevertheless, please accept my apology.
