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.

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 .

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.

      WTB noltec r32 front upper (camber) arms

      By Matvei27 · Posted

      I have offset Nismo brackets so the fact the gktechs can pivot is less important to me. I have 170mm JIC arms with bushings - but they provide no adjustment and I'm not sure whiteline eccentric bushings will fit them (I don't want to ruin the bushings currently in them to find out). Ideally I want something with bushings + adjustment; hence why I'd like to find a pair of these. Unfortunately they aren't easy to find.

      Brake pad Compound suggestion

      By Murray_Calavera · Posted

      @Vee37 How much do you really care about finding these pads again? If your pads are quiet, work well and produce minimal dust, really isn't that enough? If you are set on finding the exact pads again, I suppose I'd do something like this -  Visit your local Jax, find out what brand of pads they carry. If the Jax workshop you previously went to had the pads on the shelf, then you can almost guarantee it will be of said brand.   I'm guessing you don't have the receipt for the previous work and pads. Can you visit a Jax workshop and see if they can look up your previous job to see what pads were fitted?  Still no luck? Put your stalker hat on, find the staff that used to work at the Jax store and ask them. Talk to local workshops, try to find out where the mechanics went to. Talk to Jax workshops, maybe they relocated to another workshop. When it comes to mechanics, its a small world. You'd be surprised how easy it is to track someone down. If these ideas don't work, shit will start getting crazy very quickly.... You could find out every brand and model of pad that fits that car... and try them individually ticking each off the list if it wasn't the one you were looking for.... If you go down this path your going to want to learn how to swap pads yourself, it is very easy, takes minimal tools and space. If you have room to park the car you have room to swap the pads. Plus you have the advantage of making sure all the brake hardware goes back in so they won't squeal!

      Just putting it out there, that's a decent list. You would be better off *not* doing *any* of that and buying someone else's modded car. Like mine. Or anybody else's. Yes it's lotto dependent and all this and that but that 70K (remember, double your guesses) could go elsewhere. Keep it stock, save your money, go lowball @Dose Pipe Sutututu :p

      Does not mean what you think it means. The continual rising coefficient is the coefficient of friction that continues to rise with increasing temperature. Not "rising during a single stop", except inasmuch as the brakes should get hotter during a single stop. The RR would not be the best choice for a streeter. Yeah....no it's not. JAX would rummage around in the "shit pads we use for all shitboxen that come in here" and install those.
