I'm come a cross a set of stock twins off a fd selling really cheap, so cheap infact i can buy it with one pay check at min. wage and still have money left over. My question is will it they bolt up? If I get them I will remove the sequ. control and run them in tandom. I know I'm going to have to create a custom oil return line for the rear turbo and some custom cooling lines, but with all that said and done should I do it?

I plain to go with a larger single turbo in the future t04e or something along that line. consedering that the stock twins can produce about 360 hp cranked to there max, for about $200 and some work I think it could be fun.

I say don't bother with them. Do you know for an absolute fact that they are in good working condition? It is going to be a pain in the *** to install them but if you insist, I would advise you use silicon vacumm lines. Unless you have your stock turbo maxed out I wouldnt bother.

 

yea, they are in good shape. i've looked at the twins before and know how much work i'd have to put into making them work. But for that price.... i dont know, i'm torn.

 

Even if they are in mint condition, they are known to puke oil seals. Also, what sort of engine computer are you running? t2's are mass-air, and 3rd gens are speed-density, there is no MAF sensor. how would you rig the twin intake?

 

While I would definitely recommend the twin-turbo idea, I think you’re limiting yourself with the FD turbos. They’re quite small and don’t like heaps of boost, so the future potential isn’t there. I’ve also got no idea if it’d fit, but that’s half the fun of these sorts of projects. If you do go ahead, the exhaust manifold should bolt right up and all the intake plumbing would obviously be custom. The AFM is a non-issue. If you’re going to run the stock ECU (but why would you?) then just install the AFM in your custom piping, like the Cosmo 13B and 20B. Hell, if it’s cheap it’d be a cool little project.
Personally I’d look elsewhere for turbos. The beauty of twins is that if you want a single to make 500hp you have to go aftermarket and pay megabucks, but with twins you only need to find turbos that can support 250hp each. This sort of turbo you can get cheap from wreckers as there as plenty of factory turbos capable of this. Internal wastegates simplify everything and the exhaust manifolds would hardly complex for a rotary!
Sure it’d cost a bit more but not as much as you’d think. It’s a bit more complex but I see that as a challenge, not a problem. And those twins are always going to spool faster than a big single. Period.
