I'm at the stage now where I'd have to select a turbo for my 20b FD. Do you guys know if a gt42 will fit in an FD? I think gt40 will fit, but I'm not sure about gt42. Thanks.

Get the GT42 BB with the big compressor wheel.



It will fit.

if it doesnt fit cut out part of the chassis

seriously, the gt42 has a 5 inch outlet for a downpipe. I can't fathom the need for a downpipe that big. I like it's flow, but damn.......

I don't want to trim the shock tower....though it won't be the only thing that's been cut.

TYSON

So use a 4" downpipe.

Just use a smaller Dp as Tyson suggested. Any more pixs of your setup?

an_juan

more to come, and lots of.

Flow it out....do the math. That is the only way to find out short of trial and error.

Give Sean at A-Spec a call regarding your question. He's done a lot of research into this.
