Thanks Gleaseman. its a Fb though - steering box, brake master, and bugger-all clearance to radiator.
i'm now thinking 8374 again. but 0.95 iwg or 1.05 ewg? On one hand the .95 will possibly spool better, but the 1.05 will require a lot less work when fitted to existing twin gate manifold, which has proven itself to have rock solid boost control.
Im going mad trying to decide!

^Except there's another factor to take into consideration... The fact that the EWG comes with a larger A/R....which the IWG does not. So your are right regarding internal vs external not affecting spool...but the size of the housing will have an impact as well as the mani=-)
Can't really find data of someone with stockports and on pump using that same turbo, so a bit worried about performance.

This is exactly the problem/ thing that i'm doubting now.. i'm on stockports and am closing a deal on a EFR 8374 EWG and 1.05 housing. But worried about how my stockport engine is going to spool that big boy even though the manifold is very well made (48mm runners, equal length etc) but still..

I don't think you will have a problem spooling an 8374 on stock ports, in fact if you had HUGE ports I would think it would spool worse than stock ports.
EFR8374 is a great turbo for these cars...no excellent.

Yeah, my decision was finally made easy when i got under the car yesterday to take measurements, noticed egr probes had come loose again and how ******* hard they are to get at with plumb back twin wastegates. Priced out some sch40 and flanges relatively cheap and nek minute I've put money down on an IWG 8374 with a well respected member on here!

Anyone care to chime in on the response difference of the .92 ar of the iwg vs 1.05 ar of the ewg for the 8374? I already have a ewg manifold and wastegate but im worried the 1.05 might not be responsive enough. It will be on a stock port fd and ideally be making boost sub 3500 rpm
