Hi

I'm building up a rebuild 2wd. Cosworth engine.
The engine is gonna run about 330 bhp on greens.


Should i use a ARP Head studs or/and con rod bolts??

And what type of Head Gasket do you recommend?

Do you have more advice about building up my engine??

Thanks a lot

Martijn

 

i used arp stud and nut kit on my 400bhp cos without any problems but i did get conflicting views on them from my mates beforehand.
i have seen them used on u.s evo and scoobs etc with 500+ bhp and they all swear by them.
group a gasket should be fine for 330bhp,no need for wrc yet!

 

You should go for gr.p a gasket and arp`s, no need for them in the bottom end before you go for 7300rpm+
The main thing is that it`s an aloy top so it "works" when getting hot, so it has to get the possibility to mowe, therefore the std. gasket not steel AND arp
