Has anyone turboed a 4.3 TBI?

[gstubbz]

Might do it if I keep my truck, was wondering if anyone out there has done it. I'm thinking either modifying the stock headers to mount a turbo or finding a set of GMC Syclone\Typhoon manifolds then finding a blow through carb.

Yes GM did it.

You wanna make something differant, by today's standards... the Busch series use to have a class that could only run 4.3 motors. They where carb'd of course but dam they where awesome....

I've seen a few turbo 4.3 builds on here, but I think they were all Vortec engines. Seems like by going with a blow-through carb you'd be leaving a lot on the table.

Confused, your title says turbo a TBI then you talk about a blow through carb. Are you keeping the TBI or going with a carb ?

I paid 450$ for a cracked set of SY/TY exhaust manifolds. Then you'll need a cross over pipe, a down pipe, turbo and some way to control the waste gate.

Check out the youtube channel 'Roadkill' and look up their adventures with the rotsun. they had multiple attempts at turboing a 4.3

I know I am a little late. You could try a remote turbo. Place the turbo farther back in the exhaust system so you keep heat out of the engine compartment and can run what ever headers you want.
