Default Need a downpipe fabricator

Is there anyone who owns a 1.8 miata (mine is 1994) that is willing to fabricate a downpipe for an SR20 Turbo and HKS Manifold? I may be willing to send one or both items and pay shipping(plus downpipe charge)

BEGi does not make a downpipe for HKS manifold. I'd be willing to do it, as i do not want to spend over 250.

Even a cheap downpipe is going to run you 250+. I think I paid $265 for my Tony Downpipe.

the cost of shipping your turbo + mani both ways, plus the materials cost of the dp is going to eat up your entire budget. Leaving $0 for labor.

install that **** on your car and have some one local fab it up.

you can buy a crappy $100 welder and tack everything in place on the car.... then pull the tac welded piece off and take it in to be finish welded by someone with a better machine and some skill. Just my suggestion.

i can't even finish my own projects.

plus I need time to whoop my gf at MLB '07. My last two games against her were like 25-5 wins.

I say ask the two guys with "turbo" in their names. They make DPs.

Ha. Me neither. I don't think anyone can. Actually I don't always remember what my projects are anymore.

$250 maybe would be a very simple single tube no bellmouth downpipe with you supplying the flanges and the car to make it on. I'm sure as hell not removing my setup just to make a $250 downpipe.

Yes, it would work. just make sure to make good tacks, cause it'll be tough to get good peneration into the flanges at first.

You'll also need away to cut the metal, a sawzall or grinder or a metal cutting disc on a chop saw works (CAUTION! on that one though)

Sorry, I think he was being "funny" by volunteering me.

It is really easy to do it yourself with the right cheap tools... or if you're clever, a cutoff wheel and some clever markings (notches, not ink) to indicate orientation--then take it to a muffler shop.

if your neighbor has a tig welder, make him weld it all. I'm sure a few six packs would suffice

local muffler shop. if you can take detailed measurements or get them the car for a mock up they could make you a bend that will sync up. would cost maybe 80-100 bucks. then use a few weld ells's and the flange and try to get your neighbor to TIG it together or show you how to do it. It is not horribly difficult but you need to be carefull and thorough with your cleaning of the product before hand. GL

dont... get some aluminized steel mandrel bends. check the member discounts section for people who can help you find those.

hint: wideopentuning / atpturbo.com
also: roadraceengineering.com
also: verociousmotorsports.com (one day ups gnd!)

you'll need the turbo flange and some way to attach it to your exhaust obviously...
