13b turbo motor to na???
 
is it posable to change a 13b turbo motor to a higer compression motor??

what kind of parts would i need if it can be done??


thanks so much for any info..


i have a 13b turbo motor with no turbo and a holley carb in my car now..:icon_tdow im trying to decied what route to go , as in eather add a turbo and fi or make it just a carbed bridgeport motor...

i am have more experiance tunning carbs and know nothing about turbos..

so im leaning toward a carbed motor.. if its worth it?

If you have no experience with turbos, stay away from a carbureted turbo rotary. You'll go through several engines trying to make it work.

You can put NA rotors (and the matching counterweight and flywheel if applicable) into the turbo 13B to make it into a 4 port NA 13B.

Carbureted bridgeports are basically WOT only engines. They run poorly in the low and midrange and are responsible for most of the "bad press" regarding bridgeports.

thanks man.. def going to stay away from a carbed turbo.. had a carbed turbo street bike and it was a night mare trying to tune..

just trying to get the best bang for my buck..

i have a good feeling this car might turn into a drag race only car..

still have to do lots of reserch,,not looking to set any records but would like a pretty quick car in the 1/4 mile..

im thinking the na 13b rotors will be the way to go..just have to decied how serious i want it to be..

If you want a quick 1/4 mile car, then you need to build a serious NA engine (peripheral port) and drop the car down to as light as you can get it.

Or, build a turbo engine for about 400HP and run high 10s on some decent tires with a full interior. :)

im thinking a 13b with a pp and some nitrous for the track...if i could get in to the 11s like that i would be very happy

thanks bud!!
