What turbo would go great with a straight six?
I have a 1969 chevy c10 with a 292 engine and a 4 speed muncie. I want to put a turbo in it. I'm still in high school about to enter senior year and i just want a truck that's fast to beat those chevy vortec engines and those hondas. I wanted to know what type of turbos are good for this like a cummins or a gt35 idk tbh. i also wanted to know what internals i need to upgrade to support this mod and what type of manifold would would go good for this and the type of carburetor. i would like the horsepower to to be greater than that of a 350. Any Suggestions?

Re: What turbo would go great with a straight six?
Or better yet: don't play that game. For the reasons you stated it's a pointless jerkoff match between guys with no vision past the city limit of their small town. Enjoy the class and durability of your truck. Spend the money you're talking about spending on speed parts and drive it cross-country. Take a tent and a toolbox and help people that need it along the way. You'll come back with way better stories to tell your buddies than who beat who's ragged out Civic and who scored who's ragged out ex.

A straight forward LS swap is far superior or if you want different a Cummins swap is a good choice.

Turbo straight 6s are a big thing in Brazil and such. There is a company that makes cast turbo manifolds for them. Just gotta do some Google-fu.

Re: What turbo would go great with a straight six?
Turbocharged Chevy L6s are the holy grail of inliners. Tom Lowe has a lot of key parts for this configuration. You'll find data on www.inliners.org The website of Inliners International. They have a special forum called, ''Blown and Injected'' that specializes in unnaturally aspirated L6s. Become an Inliner and you get a parts discount.
I would try the middle step of hi-performance intake [Offy, Clifford] a 4-bbl carb and headers first. Engine rebuilt and bored .030 over. [Add HEI]. You may be happy cruising with a set-up like that. My '68 C/10 Stepside has been rigged that way since 1978 [when I was in college] and it has a lot more guts than a crate 350 in my '71 GMC Jimmy. All that being said, you could either afford to go to college or rig a turbo 292. Choice is yours.

Good Lord, 'why' is the only word that comes to mind. Just add two cylinders and call it a day.

We won't even go into what it would take for brakes/tires to make it safe at the speeds you may be talking about. Then there is driving ability/experience. Wheeling around a small car v. a top heavy truck that was designed to haul weight and corners like a dishrag, they are entirely different skill sets. (Apologies to everyone who has made all the suspension and handling improvements. Just trying to outline the hurdles.) I'm just and old fat guy with not nearly as much experience as most of the others on this forum. Built a few hotrods and helped many friends with theirs. Strictly my opinion but girls are way more impressed with something that looks cool, is comfortable to ride in and has a good stereo. For the amount of money it would take to make your truck super fast, you could do a lot of paint/body work/customization and make this one really unique and sweet ride. Something you would want to keep for a lifetime.

Re: What turbo would go great with a straight six?
Trust me, I have performed this mod several times and will never do it again...
The engine structure will simply not stand sustained turbo pressures, even with $ 15,000 in the bottom end ! Billet crank, billet rods, forged pistons, 4 bolt crank girdle...wild head and valves...twin turbos and fule injection...and the race truck only weighed 2300 pounds with me in it... but These old stovebolts move around so much along their centerline its impossible to keep head gaskets or cylinder walls intact...remember, you are working with 40 year old castings... If you want to go fast, buy a race car... If you are looking to impress the ladies...clean the truck up, put a/c in it, new carpets and seats and a good sound system... Nice to see a young guy interested in an old truck, but seriously...why do you need to beat these guys in a truck that weighs twice what one of their rice burners does and has half the HP...at best...remember your Physics Have fun ![]() ![]() ![]() |
