does any body know where i could get a turbo for my 1991 blazer.
turbos are hard to find for our rigs but superchargers are all over and you don't have to deal with turbo lag. Heres a good link
I ran across this
Try these guys. IF anyone can help, it's Banks.
How can we help you find a turbo when we dont even know what motor you have
damn I'm watching that Air Research turbo Its meant for a carbed application so it isn't any good for him.
I didnt even think about the turbo being for fuel injection.
To run a turbo on a 91 TBI blazer would require a lot of Chip work and some time on a dyno. Map sensor does not like the high boost that turbos can give and may not work at all.. Prolly take a real wiz at chip building to make one work with TBI. it would be a lot cheaper to convert to a carb if you want to go with a turbo.
I think you would be better off going with a Supercharger. Whipple, Vortec, and Holley make bolt on superchargers for TBI trucks.
try Wayne at GearTechHD.com
Geartech can fix you right up.
this is the new twin turbo kit from banks for a SBC:
Pretty damn sick if you ask me, not what i would want in my truck i dont think, but if i was building a street rod, hell ya sign me up
I AM building a street rod out of my 91 GMC SUB and that is the setup I'm shooting for.
The turn key from Banks is $38K, which I don't have.
However, I can have mine rebuilt properly (7.5:1 compression) for $4k, the twin turbo is $6k and then just add TPI ($4k from Banks - hoping to find it cheaper some place else) and I'm set on engine mods. TOTAL if I have to use Banks TPI is about $14k. Less than half of the built Banks motor.
get a factory TPI and mod it to work.
two turbos on an sbc? better have a damn good bottom end.
superchargers and turbos are definetly badass but wear the motor out ALOT quicker than I would want. If i had the $$$ I would try to get as much hp as I could out of it before I spent that much on a twin turbo setup.... You can build an aluminum block 400 that will crank out 600 hp naturally aspirated and do it for the same cost of the banks twin turbo setup-around 11 grand. I plan to put something like that in a camaro in the future; oh man an aluminum block 400 that cranks out 600 hp naturally aspirated in a tricked out camaro with an all wheel drive kit...... I think I just...........Yup..... I just had an idea.
Or you could go with the iron block 400 and spend the extra 2 grand on a supercharger. that thing would show up stock cars.
you could build a blown or turbo motor that would last just as long as a naturally aspirated if you built to fit not just slapped one on a stock motor. Even then, low boost and you'd be good. People run those bolt on supercharger kits with LOTS of miles on them with no issue.
I still doubt they would outlast or last as long as a naturally aspirated motor.
amazing all the ricers with 150+ miles on the original turbo motor
Im just saying if you can build a motor that doesn't have to deal with excess pressure and turbo lag then why not... that extra $$$ can be put into high end internals and fuel delivery system without stressing the motor as much as any kind of boost will. Its a known fact that a turb/supercharged motor won't last as long as a naturally aspirated motor. I've seen 350's that had over 300,000 miles on em and still had enough guts to light em up bone stock. 150+ is good but if you consider that to the life of an equally powered NA motor its not much.
