i wouldnt be wasting to much money on the head, all you need to make that power is drop in cams, upgraded springs, and cam gears for fine tunning.

a GT35 turbo or equivalent would be all you need.

CP Pistons 9.0:1

argo pistons will be fine check with engine builder for specs.

you should also keep in mind the costs of block & crank prep work. around that $1500.

before you start sending any blocks away have a clutch pressure plate, flywheel and the harmonic balancer sent to the machine shop with the block & crank to be balanced all together.

i get my machine shop to supply my with the correct bearing to suit.

hey thanks for getting back to me so quickly :) so are u saying that the valves and buckets+ shims are good for that much power? i have cam gears already

also i sent argo an email about there rb30 h rods and i worked out that there .160 thou smaller then my machinist said to get can anyone confirm that will be ok??

as for prep work my mate is the machinist lol and block was free (winning)

as for the clutch and flywheel is it rb30 or 25

Any aftermarket oil pump will do the trick. Tomei, Jun, HKS, Nitto or any other brand name pump. They all flow a shitload more then standard and will do the job fine. You will just need to get a collar.

You can get the tomei valve springs if they make them to suit the neo head. Tomei cams are fine. IVe only ever used the type a poncams. But cant see why the type b wont work. The Supertech valve train gear is great too. Especially since the dollar is so good atm. Not sure if they have stuff to suit the neo head though. I think thats the limiting factor with the neo head is lack of aftermarket parts in comparison to the rb25det head and 26 head.

What sort of specs are you after exactly on the H beam rods? Virtually any aftermarket rod will suit, so long as its for an RB30, Spool, eagle, argo, nitto whatever. The power you are going for is not that big that it warrants anything special. Piston choice is much the same. CP's will be fine, JE's or Ross or whatever your choice.

If you are using the rb25 gearbox, then use all your rb25 clutch and flywheel gear.

It's also a fairly loose power guide mate. A turbo to suite 500hp is vey different to 700hp. Eg. Gt35 wod be best for your 500hp goal, but won't do a whole lot more very comfortably. T04z will get you 600hp at the wheels, but will be a fair bit more lag compared to a gt35. And still, a t04z won't get you to 700hp. The engine build involved is the same for those targets, but the different turbos will make for a completely different car to drive. If it were me I'd stick to 500hp as I still like a little bit of response.

Nitto oil pump would b my choice as well. Heaps of praise around the forums for them.

I think te bigger factor rather then what pistons and rods you choose is how well it's put together.

Is this car for street or track?

for track work make sure an enlarged and gated sump is part of the parts list, even the best built engine wont last long without oil pressure.

Be careful with piston choice if you are using a neo head as they have smaller combustion chambers.

Type B 260 deg poncams give a slightly lumpy idle but seem to make more power everywhere on a 25 so they should be fine.
