So I'm planing a build now.. I have a stock RB 25 turbo, what am I in for?, It's a t3 flange, has oil and water along with a 7psi wastegate. I'm planning on using this on my 1.6, also there's a brand new 240 turbo mani with external WG bung at my local junk yard(they only wants 50 for that) If things align correctly, which I doubt, I want to get that mani chop off the flange to the engine and weld on the miata flange... and now a few questions?
1 Am i getting over my head
2 does anyone see this happening
3 Am i retarded for trying this........
Any suggestions or comments?
All are appriciated?
thanks,
Paul

 

I think the amount of work to fab up that stupid 240 mani with a miata flange would be 10% less than just making your own mani.

 

lolol well i figured a much, what i really need is to find a nice used FM mani with a t3 for a 1.6... that would be nice, that would be the only way the thing would mount up to be honest, I guess the only reason I'm asking is because my buddy has the turbo. and if i could get it to work then hell I'll make it happen.

 

So after some research I could get the begi t3 side mount mani for the 1.6 but, god thats a lot of cash for it...(410 ish) then again I'm cheap and broke lol. well it would line the turbo up exactly how it should be, so this may be the option I have to take.....
still would it be worth my time for this build.

 

Is anyone using this turbo?? lol

 

Is it a t28BB? or journal.

 

journal

 

Either way your going to have to get a custom downpipe. On my project car im using a t25 turbo for it and im going to build my own manifold/downpipe

 

yea i Know on the DP just wieghing my options i guess..

 

IIWY I'd snag that 240 mani, sell it for profit, and put said profit toward a proper manifold. Even if you sliced off the flange, the chances of it even lining up with a Miata engine's ports is slim. People are always parting things out here, hang out and snag the next decent manifold that comes along.
