What about the turbo manifold? Has anybody tried the OBX ones on ebay or does anybody else have any cheap alternitaves? I've seen some homemade ones but am not sure if I can properly design it to fit in my required space.

From what I have read on here the OBX and SSautocrome manifolds are cheap for a reason. While they might work for a period of time they will eventually fail on you. Most people who go DIY end up spending the money on the BEGI manifold because it well worth the money. There is also the ETD Racing and Flying Miata manifolds out there.

Do you know what flying miata is selling there new manifolds for? I know they recently redesigned them using a bunch of expensive crap so they'll probable charge out of the wazoo.

No clue what their manifolds are going for. I dont think anyone on here has actually called and asked. You could be the first one, give them a call monday and find out. Then post up on here what they say.

i run the megan racing stuff It is mitsu though and the DP needs a 7 degree bend to fit properly other than that and some cracking isues it has been good

there is also the AVO manifold made here in my home town of melbourne australia. these fit the garret t25/28 style turbos.

this is a very nice bit of kit, but not cheap.

i bought one recently.

$500

the 2 piece dp is $400 total too.

with that sort of attitude you should do well here... welcome to the forums.
