Default What downpipe works?

I have a pretty simple question to ask. I have everything I need to turbo charge my 94 miata but the downpipe. I have a eBay cast iron manifold. My question is would the fm downpipe an the begi work with this manifold?.

I would assume you have 1.8, I haven't tried it yet but since the manifold is an older begi/fm replica I would assume the begi/fm downpipe would fit, but then it also depends on the turbo you have and whether it's a t25 or t3. Include more information so we can give you better answers next time

The gt2554r never came on the sr20, the sr20's only came with a journal bearing turbo's. The 2554r is a ball bearing turbo, with that being said using the 5 bolt flange and the fm elbow+ down pipe should be able to fit

So what about the begi downpipe? Does that one work as well.

Fm setup will work with the manifold Not the begi. I'm trying to avoid trying to have one fabricated at a shop.

That is actually incorrect. Blacktop SR20DET's in JDM S15's came with the gt2554r. The more you know.

I don't mean to be that guy but the s15 spec r is the only dual ball bearing turbo.

The S15 spec r one is the one that will make high 2XXwhp and the others are more ~220-250whp with marginal differences.
