Hey Bro. Was there something you wanted to ask about the 20B Motor? Hit me up, let me know.

mazdatrix site has no info about not using for turbo motors, but it is posted on RB site link below.
Aluminum Main Pulley - Double Sheave for 74-92 Rotary Engines (All) - Racing Beat
because it slows the water pump at high RPM (drift) I think the benefits outweight the negative, would u agree?

just read through the entire build
question about the double sheave main drive pulley. Per the RB website they don't recommend use for turbo applications, because power is made in lower RPM. You also have a whole punched or light weight flywheel which reduces rotating mass as well.
I was staying away from reducing the rotating mass assuming it would effect my midrange power band, does the power band just move to higher RPM?
Do you notice a higher revving engine or less torque because of those items?
I drift also using stock t2 pulley/flywheel, I'm wondering if there would be an advantage to installing the RB pulley on the turbo motor.

that engine is a series 5 engine, it wont be plug and play in your 88. you need to find a series 4 engine, harness, ecu, mass air flow, and pressure sensor. if you use a turbo trans mission youll need a driveshaft from mazdatrix, na to turbo. dealing with these engine importers can suck, so becareful and get as much info as you can before you make your purchase.

the car already runs and is in great condition i just want to swap the engine for that one..

hey man so im buying a 1988 rx7 NA. i plan on putting COMPLETE PACKAGE JDM ENGINE 13B S5 TURBO 2 Rotors 88-91
