gt35 or s366
Hey I am about to start my single turbo conversion and before I made my decision I thought I would ask the experts. On my 94 fd I have a ks v mount ported throttle body upper and lower intake and 3 inch exhaust. Also a tial Bov and 50 mm turbosmart waste gate. Ecu at the moment is a knight sports one but I'm leaning towards going with a microtech. More or less the two turbos I am leaning towards are a garret gt35r and a borg warner 66 mil. I daily my car and am looking for something with good driveability and response not a race car or.dyno queen. ny help is appreciated.

Have you thought about the Borg Warner EFR turbo's? The thing that is cool about then is they have lighter weight titanium wheels....which drastically lowers the moment of inertia on the wheel...and doesn't take much energy to spool them. Speedjunkie has one in EFR7670 size and his car rips up here in high altitude CO. You might even look into the next size up which is the EFR7483. The turbo starts spooling around 2,000-2,500rpms on his V-mount......and hits mid 20's PSI boost pretty quickly. It also sounds pretty good and pulls hard up top. He has the dual wastegate external option 1.05 size housing. Be interested in seeing something run the EFR7483 and see what results they get.

I am running the aspec t4 35r 1.06. Full boost by 3800 rpm and pulls hard to 8000. Its does not fall off with 1.06 on the back. Running a microtech lt8s. Wouldnt change a thing.

^^^Good write up on the BW efr series... 7483 seems like it would be a beast on a street driven rotary...

have fun waiting a year for a turbo..... It's worth it to get something a little more off the shelf that has been proven reliable and powerful on a rotary. Can't go wrong with the s300 series turbos or a T04s

I've toasted so many Garrett turbos it not even funny. When I say I toasted them I mean they either leaked from start-up or they couldn't handle the hard driving. They've been getting their parts from Mexico for years. I've used both for years and years and have yet to have a problem with a Borg Warner. I've literally beat the snot out of them whenever I can. In the even that something goes wrong (even though we have bendable seals that cure the problem), you can rebuild them and replace wheels at minimal cost. As far as spool I have yet to see any difference.
I'm working on a hybrid turbo right now that should work out very well. I'm hoping to have a full built car at the Chris Carlisi meet. I'll discuss anything to anyone that wants to listen. We all have opinions, I'm only speaking from my direct experience over the years.

Personally I'd go for a S362 FMW, which is a great turbo for $1K. It's right between the two turbos in terms of the size, but with the latest billet compressor and turbine..
Also BW has great reputation for being reliable
if I was building a 13B turbo car right now, that's what I'd try first...

BW have a pretty big physical size compared to standard Garrett's. Here's the dimensions.

Only thing is the heater core hose has to be moved up but then its still looking ugly next to the turbo or it has to be relocated under the turbo. Wherever you want to move it.
