more like too old and dated for 500hp.

If you want 500hp (now, one assumes thats @ the motor when you make no mention of rear wheels), then the good ole GT30 fits that.

If you mean 500rwhp, then thats GT35

To the engine.

Im getting a whole single turbo with the T04s set up for real cheap and I was wondering what its capabilities

If you mean the old HKS RB26 kit , split pulse single low cast manifold , the turbo should be a "TA"45S so the next size up from T04B/E/S .

A .

I don't have the ta45s I have the so called T4s "T04s" .Just wondering If i should sell it ,basicly new it was just reconditioned and now im thinking its not enough for me so i'm thinking about fitting a gt4088r down there.If it will fit?

For 500hp @ the motor, why on earth are you getting a turbo capable of around the 700hp mark @ the motor?

GT35 like i said will do 500hp. Best to get a turbo suited, rather than something not thats only going to add lag for no extra gain towards your goal

I assume its a HKS T04S. I had some stats on it as I used to have a HKS T04R and done a heap of research.

Its only a 500 or 550hp rated turbo and a GTR I drove with a HKS T04S turbo was massive responsive and still made 300kw atw. One of the best GTR's for power delivery I have driven... :P.

Will try and find the old info I have saved. I assume you have a HKS T04S kit?

To be sure if you can post pics of your turbo (front/back/side/ID Tag) I should be able to identify it for you - well at least which series anyway .

There is a lot of variation in what gets called "T04S" or "T04R" .

Normally T04"S" means the 3" or ~ 76mm 7/14 blade T04S series compressor and T04S 0.70 A/R comp housing on the front of a garden variety T4 cartridge .

T04R as in what HKS used to sell as a T04R turbo just had the "R" or 84mm 63T BCI-8D compressor wheel fited to a T04S turbocharger . I think HKS may have been cropping the T04 P trim turbine at one stage but thats nothing any reasonable turbo mob couldn't do .

I used to have a couple of pics of the HKS spec TA45S and if I can find them I'll post them .

I can't figure out how to put the pics but if you give me your email I could then.The guy that sold me the turbo just had it rebuild so its like new now and he said it was supposedly upgraded with a bigger wheel....and spooling full boost in the 5k range which i though pretty hight for a bb t04s..I guess i'll sell it and buy a t04r instead.

lol dont get a t04r. old technology

get a t04z!!!! (thats if the t04s isnt good enough)

The one I drove on a GTR was FULL BOOST 4000rpm and Flew like the clappers with massive midrange

first you need to decide what final power figure you want, and what you using it for? Drags, street, circuit etc etc...

I need a wall to belt my head against.

5000rpm??? for only 500hp? Madness.

Maybe you've missed it the two times before

GT35

Not T04R, not T04S, not even T04Z - GT35!

Ball bearing T04S ? That would have to be either a large frame P trim/60-1 or a T04Z . How many compressor blades ?

A .

It has 8 blades ,I didnt receive it yet ,its on its way and for the gt35r its out of my price range for the T4 version.

I'm looking for 550 to 600 hp at the fly ,going to be street /drag once in a while.Dont mind a turbo that has a little lag like ex:boosting at 4500 to 5000.

For 8 bladed , what I call 8/16 because they have 8 full height a 8 splitter blades , I think you must mean th old T04B series . There were actually a few 6/12 balded wheels in the B series - the largestbeing the T04B H trim .

Pics when it turns up , A .

So is the T04B rated to more power then the T04s?I have pics i just dont know how to post them...

No the other way round I think . All the T04B wheels I've seen are ~ 70mm OD or 2.75" where the T04S ones were ~ 76mm or about 3" .

My lists show T04B 6/12 (39 to 70 trims) and 8/16 bladed (39 to 63 trims) , plus T04S (TB41 ?) as 7/14 bladed (34 to 58 trim) .

A lot of variation here so I need ID tag numbers and some pics of the turbo preferably with the housings off to know for sure .

      Is there a good place to learn how an engine works online?

      By joshuaho96 · Posted

      Do a degree in mechanical engineering specializing in combustion systems and materials. Learn how to actually wrench on things that don't require 70k+ USD buy-in while you're at it. You also want to learn to weld and machine. If you still want to do this then you'll nominally have the knowledge to actually do what you're thinking of doing. Whether you still want to do any of that once you've actually gone through that process is anybody's guess. Personally I cannot imagine anything more frustrating than trying to package a supercharger under the hood of any of these cars when the turbos are already fighting for every last inch.

      R32 GTS (RB20DE) Injectors Replacement

      That's a function of the fuel pressure reg, not the pump. The pump can do more, needs to be able to do more. The reg keeps the pressure in the rail constant above whatever the manifold pressure is.

      You need enough post count to have PMs enabled. It will come. They are not the same. The NA box is the skinny little box and the turbo box is the big heavy one, and the yokes are not interchangeable.

      Rebuild Original Nismo Struts (R32 GTR)

      So, you're not talking about rebuilding the dampers, just putting new tops on them? You just need new tops and a spanner.

      Rebuild Original Nismo Struts (R32 GTR)

      By T0m · Posted

      Hi All, Does anyone know how or who (shop) could rebuild my original R32 GTR Nismo struts? These are the OG logo ones that were a factory option back in the day. I've replaced them with aftermarket coilovers which are good, but the OG Nizmo struts tha i bought the car with i feel are amazing, just the rubber tops are worn and would need replacing... Plus it would make it 100 time easier for me to get the GTR fully engineered without adjustable coilovers... I was considering selling the OG suspension, but if i can get them rebuild / refurbished, I would seariously put them back on. Cheers, Tom   p.s. I'm in Sydney by the way and don't mind travelling if need be to get these puppies rebuilt.
