13BT in other mazdas??
 

Are there any other mazda's that use the same s4 13BT in their cars? I got a source on a 13bt, but the guy said that i have to change the intake and exhaust because the motor came off a sedan in japan? Does this make any sense to anyone?

Thank You, Ut

Maybe a Eunos Cosmo with the 13BTT. Sequential Turbo. I know a few people have done the swap. It's pretty much the same, except the exhaust ( TT Manifold ) and the upper intake is different.

yea, i kno bout tha cosmos, but i dont think it ever used tha same s4 13bt's though? anyhways, thanks for ur reply

The 86-91 HC Luce (pronounced Loo-chay, aka Mazda 929) was sold in Japn with the Series 4 13BT (auto only), but it's exactly the same engine as in the RX-7. No manifold changes are required, only a gearbox and clutch.

thank you, if it came wit an auto, i still wouldnt have any troubles fittin my 5 speed on it right?. from the flywheel back, its all the same?

thanks

You need to replace the flexplate and torque converter with a flywheel and clutch, but the rest is the same.

"It's pretty much the same, except the exhaust ( TT Manifold ) and the upper intake is different."



its not the same engine as a series 4. its like a series 6 but with bigger ports.

Theres no scoop fer the IC on that car? Also, I seen someone put a 13BT on the Mazda B2200 Pick up Truck, it looked really pimpin towing his 88Tii.

There's a duct on the underside of the hood that pics up air from in front of the radiator. Not great but better than nothing.

so, has anyone swap their tIIs with the luce motor in this forum b4? I jsut want to be sure and not find any surprises when i swap mines out.

thanks :)

i think you will find the motor mount brackets different than the luce

Yup, motor mounts are different. Oil pan would not clear, several misc sensors (oil p., water temp etc) water neck/thermostat housing, ac and powersteering are reversed. I just put a luce 13b turbo in my 1988 s4 n/a. Overall fairly straightforeward (so far). Motor and trans are mounted in car. Going back down to parents house in a week or so after exams to wire engine, replace all vaccuum lines, ecu and exhaust. Using na wiring harness after weirdly rereading hailers posts over and over again until everything was memorized. Hopefully no issues with luce engine, i ordered it from corksport who said compression is great. We will see in a couple of weeks.

sorry to revive an old post, just wanted offer some more info to the "luce" searchers.
