has anybody done a twin turbo fc
i was thinking of converting my tII to a twin turbo.
does anybody know somebody or has done this conversion? |
Not TT yet but i have 2 turbo's in the corner that say that won't be for long!

i'm using 2 small turbo's on a N/A FC to get about 10 - 12 psi but basically as little turbo lag as possible.. and full boost through most of the RPM range..
Turbo's didn't cost shit so it's still kinda up in the air |

yeah im building a Twin GT30R project car
|
i know someone who is building their fc... and they have twin to4 turbo's on their motor..... its pretty crazy.,...

Originally posted by NZConvertible Yeah, because it's easier, but that doesn't necessarily mean it's better. Two turbos that can flow the same as one big one will spool faster, improving mid-range and making the car faster even though peak power is the same. The obvious downside is that it's a lot more work to fit them in, but then you don't get nothin' for free in this world. And to answer the original question, yes it has been done before. Thanks |
If you are really thinking about doing it i have a set of cosmos 13b-RE turbos i can sell you cheap. I have sold these before to FC owners but i havent seen them on yet.

The stock turbos fitted to FD/JC engines are okay but have limited potential for improvement. The reason they're often replaced by a big single is not because they're twins, but because they're two small to make serious power and are difficult and expensive to upgrade. They're also at an age where they probably require a rebuild anyway (also expensive).

Ive got Cosmo turbos laying in my garage taking up space too. If you want em PM me.

Stock Mazda twins are a waste of time...

any pics- particularly of the manifolds? what spec turbos have people used?

Originally posted by amused i know there's an FD on this forum who would totally disagree with you there. sure you can make big hp on them, but at great cost to reliability. a friend of mine spent a year and 3 motors, and 3 sets of turbos to get 378rwhp on an fd, when he could have bolted on a t04 turbo kit and been done with it |
I don't think those who have gone non-sequential have nearly as many problems as those running the stock sequential set up.

more pics!!!!

whats up with that twin intercooler? why not just have both turbos dump into one IC?
|
if you have the money to do twins right you can really put some numbers down to the rear wheels.

Originally posted by amused i know there's an FD on this forum who would totally disagree with you there. The stock Mazda turbos all run carbon seals on the compressor side, and these are no where near the reliability of a dynamic seal. Most of them puke these seals in very short time. A single turbo can be bought with a low budget (i.e. fc3s.org < $500 H-trim) that will produce similar numbers as the twins will. Add an HKS collected turbo exhaust manifold, and you have a "budget" single turbo system around $1,000 that will produce better and more reliable power than the stock twins will ever do. Hell, if you're willing to experiment and got the stock twins for cheap, go for it...remember, you need to shim the turbos from the lower intake manifold, make a custom downpipe and intercooler pipes, new oil supply and rain lines, and new coolant supply and drain lines so you'll need some kind of budget. -Ted -Ted |
I think we need to forget about the stock Mazda twins altogether. Unless you have the resources to do it on the cheap, it's just not worth the effort. Anyone seriously considering twin turbos will most likely want more power than they can reliably offer, and will be looking at a custom set-up rather than OEM.
