went for mapping and it wouldnt hold anything more thank 10 psi, went to wgt, checked all the rats nets and check valves, and all the simple things, so i thought it was a good idea to sort the blowing exhaust out, sounded like it was comming from the manifold then i found this

Just remember that this manifold is getting on a bit now and would be OEM, they do crack due to the crazy heat the rotaries kick out, you can either get a replacement one, or \'accidently\' get rid of the twin turbos and \'accidently\' only bolt 1 turbo back on :D

so wanna go single

ok good question, suggestions for turbos on a standard port that will make roughly 350 fwhp, spool nice and quick, also cheap as chips lol:wiggle

I am yet to see an FD Manifold not have cracks on it.. And I have seen far far too many! ;)
Yours look rather bad as it\'s breaching the gate, look for a replacement or if afforded, go Single and have a happier Car all round.

Wait I thought you are running an advert selling the Car as you are broke??? :rolleyes:

yes i was gona try and sell it and get a crap s14 or volvo and pay off some debts

but i think to be honest i can just park this up for a while and build it and pay off some debts at the same time

the car doesnt owe me anything so i might aswell just let it sleep in the garage for a while

sorry for the slight thread-jack, but does anyone know if you can get these welded up? a proper machine-shop or metal worker\'s should be able to do it?

not sure! i would prob end up swapping the turbos into a nackered pack and use a good manifold.
