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 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!

      I would hope so. I worry that it also might depend on whether the person working on the claim has had a good day or not. I could imagine that for example modified brakes would be an easy thing to point to for affecting the outcome of an accident. I don't know. I will keep paying my premium and hope for the best. But at the same time keep safe distances, drive defensively and avoid dickhead P-platers in lifted utes

      I was just working on the assumption that a cammed V8 is significantly less polluty than a Japanese I6 turbo was at the way they tested it in an IM240. Perhaps I'm wrong! Perhaps cutting one of the readings I got in half is a tall order. I don't know too many people who actually got their cars emission tested with a RB to really compare the data.

      I thought it was just if “the modification effected/caused the incident”

      Ok, good to know. I have open loop I think, I forgot which ones which but I am running the o2 sensor, brand new and I got a new boost solenoid because my last one was faulty and overboosting by a lot, but it's still technically overboosting. Haven't really bothered to hunt it down as I don't send it hard regularly.

      You should not be able to see much smoke behind you if the mixtures are good - for ~13-14 psi anyway. It's not like you need to be running hell rich for only that much boost/load. Your tune might be a tad too rich. The tuner might have done that because they like to run a lot of timing. It's impossible to know what's going on from here. It won't be the actuator. It won't be the MAP sensor. Regardless of if by "MAP sensor" you mean either the Neo ECU's boost sensor (which is literally only that, a boost sensor so that the ECU knows a) that it's achieving boost, and b) that it is not overboosting) or you mean the dash gauge's MAP sensor (because it can't have any effect at all), or you mean the boost controller's MAP sensor (because it is very unlikely that it is running in closed loop, and so it is effectively just used to know when the pressure goes positive and so you can see the boost on the display, for the most part).
