Can someone list a few possible, fairly common turbocharged cars with the proper size turbo for a 13b 6 port EFI gsl-se engine? Eg - someone said that the turbo's off a mid 80's dodge LeBaron/omni/lancer 2.2L would be too small for a rotary. Thanks.

 

if you have access to one, i would say go with a turboII

 

i wish... not an option around here.

 

The problem is, the turbos on piston engines are sized all wrong. I've been looking into it myself and the nearest thing to possibly useable that I could find is the turbo from a late model Grand National, the compressor looks like it's fairly close for a mild 12A but you'd still need to get a different exhaust housing, because the stock one is too small... so that $100 turbo now turns into a $300 or so turbo. For that price you might as well hunt for a T2 turbo from partstrader or ebay.

 

Ask Setzep, I think he wants to sell his twin turbo setup from his Cosmo motor

Low boost like those produce probally would be OK, on your N/A motor..

 

I was personally thinking of using a pair of RHB5 turbos, the exhaust side totally divided (each rotor has its own turbo) but the intake side bowing into a single intercooler. Problem being, they might spool up too quickly and go into surge.

Someone on the single turbo section (Magnus?) said that, generally speaking, if a turbo will make X horsepower on a boinger, then it will make about 2/3 to 3/4 that on a rotary.

 

thanks peejay, i guess its not really an option then at this time... later

 

could you turbo a 12a? (1984 rx-7)

cheers'

 

sure can.. most of the 12a's in japan were turboed

 

You can turbo anything you want, all it takes is a turbo, manifold, oil and water feed/return lines, more fuel, and a lot of work

 

hmmm....
(the gears begin to turn)

cheers'

 

-g00d question about a stock turbo.
I find that if you use a small AR on the exhaust side [13b Streetported] you'll tend to over spool the turbo. Which in turn makes the turbo glow orange and heat soaks everything causing you to actually make less power.
I stated off with a AR of .60 which with a 2.5 inch down pipe.. and extended all they way to the muffler with a HKS 2nd Gen turbo muffler.. [one side of course] spooled very quickly.. <8 psi around 3700rpms> and pulled strong with about 1psi boost creep around 6500rpm. The choice of intercooler was a 89 Conquest.
But.. 2nd 3rd and 4th gear runs.. I tend to rev past the 7000rpm redline.."force of habit" around 7500rpms. The compressor side was flowed at around 700cfm. After a few hard runs.. the turbo started to glow orange.. and the the car felt like it was strugling in 3rd and 4th. I then counsulted a friend with a turboII and was told to use a bigger turbo.. because I was over spooling. I then bolted up a TO4B.. with a .81AR and a 1200cfm Compressor. Now the motor started to build boost around 4800rpm..and pulled strong all the way to 7500rpms. Eventually I went to a 3" downpipe all the way to the rear muffler. At that point..I notice that again the boost curve changed to around 4900 rpms and I had to learn to shift quicker :]
