Block Work -

[GTSBoy]

If he's "porting and polishing" the head for $660, then he's really only waving a die grinder over it briefly to clean up a few casting dags and that's about it. Either that, or he's got no idea what he's doing and he's just going to hog it out. Refer to my first reply on page 1. I reckon a decent porting job can consume $2000 easy.

Looks like no porting on that one though , try supeflow heads at Liverpool I've seen a rb25 he was doing looked pretty good to me, wherever u go I think you are within your rights to see examples of work. Like in west ends case I know they do some of jems engines but I doubt they will tell you that. Ask who ever you go with exactly what porting and polishing you will get for the price

[Reese69]

ok thanks for the pointers

[Adriano]

are you sure you need the head ported, what turbo and power are you hoping to run?

[SilverECR33]

buy my head, it will save u alot. i got a fully prepped 25 head sitting on my workbench, fully machined for a 30 bottom end.

was gonna use it but i dont know if i can be assed to rebuild another motor.

just get urself a new set of lifters and ur good to go.

i have a garret 35/40 at the moment but considering a change..

looking to run 360kw - 420kw.. may never get that hight but best to build motor to handle

Looks like a stock head would be fine with some Tomei cams

[Reese69]

really ok well that should save some..

[Simon-S14]

i have looked at hime seems like alot for stock internals

they will do 600 rwhp all day every day with decent fuel and tune

[Simon-S14]

forget porting..my 26/30 makes 400 rwkw with 35r with stock head and stock rb30 block.

just buy this
