Default Im poor..

OK not really, but my parents cut the chord quite sometime so all the fun stuff to waste money on comes out of my pocket..lol (im 19, money is tiight!)

OK so..i turbo'd the 1.8 motor in my impreza and the engine is **** (woodruff key slot is oblonged, timing belt tensioner threads are stripped) so i put it in anyways and hoped it would last. i didnt blow it up but i got another ej18 block with lower miles on it and its in good condition so i want to put that one in the car.

the previous motor has like 30 miles on it with the ej22t heads and wrx headgaskets..

Can I re-use the HG's?? Im gonna be using ARP head studs with this motor also...

Thanks guys.

DONT use ARP head studs. Use the stock bolts. Use factory head gaskets. NO you cannot reuse ones that have already been used.

I would save your money as well and not run the arp studs...overkill for your biuld...put the money into new gaskets and a used 2.5rs motor or wrx heads...

blaa the 1.8 is gonna stay boosted for some time until i get rs heads and a 2.2 block so i can do a big hp motor..the 1.8 is just to learn on and go fast

im gonna be running like 18-20 psi through this thing once its up and running again (td04 turbo w/ fmic)

u sure arp's arent worth it?

Yeah don't worry about ARPs. Stock bolts will go over 500whp with no problems.

HMm.

How much WHP will require ARP studs?

Or is that a boost related type of thing?

it is in cylinder pressure...bmep...basically your hp level...not boost pressure as boost pressure doens't mean hp...
your EJ18 will not be capable of lifting the head with the factory studs...you are perfectly safe.

i think the block could support 300 whp for altitle bit..would that be enough? im not shooting for that # though but i would think that might be enough power to lift the head..lol

You can get metal 3 ply 2.0 gaskets...... I know cause I have a pair that was sold to me accidentally when I ordered 2.2t gaskets....

nope 300 isn't enough...maybe wipe off the 3 and put a 5
which at that point you wouldn't be on an EJ18 block and EJ22t heads either as the heads can't make that power and the EJ18 block would have to be built and would have some high rpms and high pressures

I am holding onto them for now.

Call Discount Import Parts at 503) 626-7036 and ask for Gerald. Tell him you need the 3 ply metal headgaskets for the 2.0 and he will know what you are talking about. Tell him Doug sent you to him. They ship UPS.

Wow EJ18 turbo... Heh I ran 14 psi on my EJ18 turbo with stock heads, and 100k miles on the motor. I really don't think a TD04 can push 20 psi without dumping heat out.

Yeah..I agree. Sort of. Some people are running 20-22 and I even read 25 PSI DAILY on their wrx's..so I dont see why I couldnt run atleast 20 with the big front mount I have.

17 psi seems to be the magic number of the td04's efficieny.
