Some opinions for a new guy please...
 
I just got a 87 non-turbo 5 speed. The engine has no compression on one "cylinder". There is a guy here in town with an entire turbo engine. He wants $400 for it. I have rebuilt many engines, no rotory engines though, but I am excited to do my first one. My questions are:

How much can I get an engine kit for, hoping the rotors are in good shape?

Should I buy the turbo engine and rebuild it, or rebuild the engine I have and turbo it?

Sorry I'm such a noob here, but thanks in advance for any info

I don't have any first-hand rotary experience yet, but I've been trying to get informed for a while for when I DO get one. I'd say get the turbo, it'll be a blast and if the one he's selling has < 100,000 miles and runs decent that sounds like a pretty good deal.

you cant just drop the turbo engine into a non turbo car. there is much more that needs to be done. there are a lot of people doing na-turbo swaps around here. search the forum and look around.

I've been reading up on that, the engine comes with all the sensors and ecu. The guy took it out and put in a 400small block chevy. This car is a toy, I have a daily driver, so I have time.

Also, thanks for the correction, I now know they are called chambers... learning something new everyday here.

do alot of searching around before you start something like this...and personally i would rebuild tha NA engine get it running and learn alot about the rotary engine and how it works before starting a turbo project.

is the turbo and non turbo engine the same "block" or "rotating assembly" other than the manifolds and stuff?

No.

Sorry, I should have mentioned that. Things like your differential and drive shaft would have to be upgraded to handle the power. It would be a serious undertaking, but if you have the time like you said you do we'd love to see you bring it to life.

Buy the turbo engine.
