T04Z On An Rb25

[REMANIS]

Basicly I have a to4z I'm wondering if this turbo is to big and what sort of revs it would spool at!

[l0WRB]

prob looking at 5500-6000rpm before u see any sorta decent boost

[TiTAN]

depends what rear housing. expect 4500-5000 for the medium sized ones more if its larger.

[REMANIS]

What kind of revs can I expect from the 25

[TiTAN]

completely stock internals? balancer? cams? etc? 7000-7500. properly balanced built engine with aftermarket valve springs 8000-8500 any more than that and you really want to go with solid lifters and a serious setup with porting larger valves, better valve springs again. the list could go on to around 11,000 if you have deep enough pockets.

You wanted a food daily driver that could be used for drift etc... this was 2 days ago.

Now you want to use a turbo capable of 440rwkw that requires a good 25,000 to support it.

Two ends of the scale dude - pick one.

Way too big for anything street driven and I wouldn't build an engine to suit a turbo anyway .

Big is just big and big isn't necessarily better . Far better off with an GT3076R if you want to stay with a mechanically std RB25 . If you wanted to build something build an RB30 and if you want something easy bolt a GT3582R onto it .

Just looking at the options mate this is all stuff I have lying around I don't have the same knowledge about jappers as I do about LS1's and if you knew me mate you would know that spending 25k on an engine setup is a cheap combo for my previous spendings on other cars.

[REMANIS]

Yeah I've been hearing that the 3076 is a wise choice!

Well if you've come from big capacity engines then I reckon an RB30 would be virtually a necessity because these smaller ones don't make gratifying torque off boost and its not like a Skyline weighs half of what an LS1 powered Commodore does .

I can relate to a well healed fella that bought himself a brand new locally delivered R32 GTR in the early 90's . Hated it , absolutely loathed the thing because he came from V8's and GTRs are heavy and Camry like off boost . It wouldn't pull the upper gears at pedestrian revs like his eights did so he flogged it off .

Anyway I reckon a twin cam RB30 with a reasonable CR would be the way to go because more cubes means the easiest foot pounds .

I don't know if an LS1 fits in a Skyline bay but geared right it would give some of the turbo ones a real big hurry up .

this is what i see with a gt3582r on stock rb25, do doubt your going to see it with a to4z.

Read Bezerks build thread...

5.7L in an R32...

[REMANIS]

Yeah the idea of the LS1 in the r33 was the original idea as I have a few ls1's lying around also, but i decided to just drop the 25 in so it would be running alot quicker!

[r33cruiser]

Not too big at all, after all its not lag, its foreplay .

Shoot anna a pm, http://www.skylinesaustralia.com/forums/user/30020-msnismo/

She built a t04z equipped 25. She was actually a great help to me deciding whether to go the z or the gt35 (the 35 won out in the end).

She will help you, I would post up her build thread, but i cant seem to find it.

[joe blo]

type in "t04z rb25" on youtube. theres a 200sx or something with one with some good vids

[JonnoHR31]

ls1 has been done into 31s, 32s, 33s and 34s.

ls1 + to4z in a skyline should do the trick

[REMANIS]

Cheers dude I'll have gander.
