Not good. It'll line up with one of their tinfoil manifolds and that's about it. If you're getting a cast mani (as you should) it wont line up. I'd strongly recommend a custom v-band downpipe.

Plenty of people. You can use the air vents or make a blank plate below the radio.

Do research. Do Research and then when you're sick of looking at forum posts... do it just a little bit more.
This will answer most, if not all of your questions and will alleviate a lot of issues from popping up during the conversion.

GUYS!!! Has anyone ever turbocharged a Miata? Is it possible?


:giggle:

Alright, so I will be going with a cast mani so I will stay away from the Cxracing downpipe. I'm trying to figure out the best way to get one custom made. If I do it before the build then I wont have the dimensions but if I do it after the build then I wont be able to drive to a shop to get one custom made to fit. How do you guys go about getting a custom one made that'll fit perfectly with an immobile car? What can I expect to pay or what are you guys paying on average to have a basic 2.5" mild steel downpipe fabbed up?

you want a good deal, go talk Lars (shuiend) into building you a mkturbo setup. or go talk to sturovo about building you a Subaru flanged setup.

Better yet, pick up a cheap mig welder, some 2.5" pipe (even better 3"), some mandrel bends, and learn to do it yourself. You will be the envy of all your car friends

I actually have a Mig welder sitting in my garage I used to weld up a mid-pipe on my Subaru. It worked but didn't have the prettiest welds. Would this type of welder be fine to use to fab up the downpipe? Would i see much of a benefit using a 3" downpipe over a 2.5" or would I even see any benefit since I only have a 2.5" catback?

Yes

"A grinder and paint make me the welder I ain't."

AMEN.

That's awesome! Haha. That about sums it up perfectly. So a flux core mig will do the job, I just have to clean up my welds I take it.

Or not care what it looks like.

My exact thoughts on my exhaust, cover the DP in heat wrap and the rest will barely ever be seen again

The bigger the glob, the better the job

Didn't know about sturovo. That's pretty cool!

I hate you.

This thread just became promising.

Too good to not make my sig. +1 for asking the real questions.

Won't heat wrap cause the downpipe to rust though?

Depends on whether you use stainless or mild steel.
Did some googling for you:
Should I heat wrap my downpipe?

VWVortex.com - Heat wrap the downpipe or don't heatwrap the downpipe?
Heat wrap down pipe....Good or bad idea??? - MR2 Owners Club Message Board

tl;dr: It's an opinion thing you won't really get a solid answer on, but nobody says anything bad about ceramic coating. Seeing as you're a city driver, I'm assuming you sit in traffic? Might want to bite the rust bullet and wrap it anyways.

Okay thank you for that, but yeah it does seem like a matter of opinion. I think I will do the heat wrap then to keep the heat down in the cabin. What are your thoughts on turbo heat shield blankets? Are those worth anything in regards to keeping temps down?

General thoughts from reading.

Heat shield = good (to protect brake MC and lines) & plenty of picture examples
Blankets = Bad (esp if journal bearing) no actual air convection.
