If i wanna take the turboII engine and convert it to n/a engine wit my other n/a parts is it hard and will it work the same. so basically ill be converting the turbo engine into a n/a engine lol dont ask me why i want to do it! its just cause i have to right now...

what im tryin to say is that i dont want my turbo engine to be turbo i just want it to be a regular N/A engine!

 

I dont know the differenced very well, but I'm pretty sure the ports are alot different- maybe some port matching? I dont know if it would run quite the same, as the NA ecu is mapped for the air and the compression of an NA motor, but nothing an SAFC couldnt fix. In any case, I think it would be smart to just find an NA keg. Also, i dont think the TII ports would make very much power NA. Dont quote me on any of that though...

 

if your turbo is fragged(only reason i could think of for doing this) then just disconnect and block the oil lines, the turbo will die(lock up) and you will be running n/a with no side effects.

there is no easy other way since you have a 4 port engine and n/a's use 6 port manifolds and there would be a ton of stuff to block off just tossing a n/a exhaust manifold on a TII running gear equipped engine.

 

so u guys think its a bad idea!

 

And the turbo has lower compresion rotor's i cant see this doing anything good. wouldnt think the exhuast would be very freeflowing with a froze turbo ethier.

 

just put an N/A exhaust manifold on(and downpipe), and make some new intake pipes, and block the oil/coolant lines to the turbo.

yes, its a bad idea. but if you want to, shouldn't be that hard...

 

I ran my turbo'd NA with NA exhaust and the entire turbo top end setup for a while after I found my turbo had a bad oil seal. Hardest part is getting the piping to run so your AFM/MAF is not tilting down. Makes for a horrible idle when it tilts down like that.
