I have been a VW guy for 20 years and this is my first rotary. I see lots of turbos' but not many draw through set ups? Is there a reason rotary's don't use them?

 

Are you talking about on a 1st gen Rx-7 with carbureted 12A engine converted to turbo?

 

Because we aren't in the 1980's? Not to mention having accurate fuel delivery is #1 requirement to maximizing a rotaries HP and keeping it reliable. Not saying it can't be done, it has been done... 30 years ago.

The stock FD uses a MAP sensor. A blow through or draw through setup involves a MAF sensor.

 

I think he's talking about draw through carburated turbo setup.

Would make sense.

Draw through carb setups are less precise than blow through, which means fewer people will use them for performance applications.

 

This is going to be used on a sand rail that is carbed now.

 

Rotaries produce heat... and lots of it. Our exhaust gas temps are easily 3-400 degrees hotter than a piston engine. The idea of sucking a combustable fuel mixture through a turbo that could be glowing just seems like a bad idea.....

With this, blow through setups are much more common. Holley's work great and can be easily prepped. There is more information in the 1st Gen section, as they blow through their stock carbs frequently.

 

Save yourself a BIG headache and get fuel injection.

I've done the carbe'd turbo rotary sandrails and its a tuning nightmare...

 

+1 aint done any more for lots of good reasons , more power and more reliabilty and less heartache and less custom fab are good reasons to go EFI

a sandrail shaking itself like crazy is hardly a good environ for a carb anyhows

 

Didn't even think of the physical factor. Another reason.

OP, with the cost of OEM intakes and something simple such as an Rtek or MegaSquirt, no reason not to go EFI.

 

+10000

I spent months trying to get my car tuned right changing jets... ordering more changing them again... etc... going with efi now... with i would have saved my money and not wasted it on a carb...

 

1st gen came turbo... It's the T1. @michael check into how the t1 was done.
