Rb25det Bhg. Rebuild Questions.

Recommended Posts

Hey guys,

Picked up a s1 25 with a blown head gasket really cheap a few weeks back. i'm gonna pull it apart and send it off to a engine shop to get the head and block checked for cracks etc hoping it was just a blown gasket.

What else should I do while the motor is out and apart?

Water pump

timing belt (should I do the cam seals? I have some brand new ones here)

VRS gasket kit

ARP head studs (I have some brand new Nason ones here, are they any decent or don't use them?)

thicker head gasket (metal?)

piston rings

it's gonna go into my 32 and at some stage im hoping for 300-350hp and maybe up to 450hp in a few years time. What should I do now to future proof myself?

I would like to stick to a budget of around $2000 but I can stretch if its worth it.

What is everyone's opinions?

Sorry if the post seems a bit stupid, i'm new to building engines.

Cheers :)

Well, seriously.

You would be mental to not replace cam seals, especially if you already have them.

Your questions are so basic and pointless, I have to wonder if you have bitten off more than you can chew.

Good on you for having a crack.

For a start you need to ( or get the machine shop to) measure the bores for wear and out of round and the bearing clearances though if it doen't need a rebore and new pistons you might as well do rings and bearings. Have a listen to what the machine shop says but don't agree to anything until you have considered all the options or you could be up for a $10k plus recond.
