Would the t4 turbo work?

I don't know much about turbos, so please clue me in...
What would a t4 actually be intended for?
A gasoline engine will typically take a larger turbo due to higher RPM operation. In this case, they are pretty close so the automatic version I listed, HY35W, with 9cm turbine housing will spool very quickly. The compressor also utilizes a map-width enhancement ring which will make it more tolerant under low boost operation and will be less likely to surge.

No dice. That is designed for a draw through supercharger application. You will want to go blow-through on all of these turbos listed. Plus, performance is better with blow-through. There are carbs available, but you can do a $50 rebuild on a used carb and set it up for blowthrough. You just want to start with one that has good tight throttle shafts so you dont have to worry about sealing them.

Qparker, I actually LOVE the fact that you're working with a 292. I was going to go a similar route with my old c10, but I'm going with a vortec 4200
you could also mod a clifford intake for multi point, and run mega squirt. THAT would be awesome to see.

NO FUEL INJECTION!!!
I already feel bad about putting a motor from the 70's in my '49 pickup, let alone putting a turbo on it...
I figured i would atleast keep it a straight six...

Now, if anyone wants to donate a 12 or even 24 valve cummins that's TOTALLY different, not an ounce of guilt
would be felt there...


And cusz28, I was just givin ya a hard time, no apology needed

GN turbo

I have been down this road before. I just completed a complete turbo system on a chevy inline 250. I runs really good. Get a turbo off of a 86-87 Buick grand national. Use a small 350 or 500 cfm Holley two barrel ( 2300 series) they are very easy to modify. If you get serious, pm me. I will walk you through it. good luck

what about some of the small diesel blowers, like one off of a 4-52 or a 4-71?

I do have A 6-71 blower Handy, and I think I'll try to use that. I'll probally have to mess with pullys to get the right ratio.
Here's how the thread is going elsewhere:

"There is a guy on the H.A.M.B site running an 8-71 on his 270 six, and he says it can keep up with the stupid little ricers on the highway, so I was thinking my 6-71 would probably work fine.
I'm not looking for a full out race motor, but I want to be able to show those ricers what a real hot rod looks and sounds like
If I get 350HP and 350ft.lbs I'd be happy, It'll top at about 10psi boost and 6000 RPM, and It's going to be a daily driver anyway...

Hank, Or somebody, Could you please suggest some cam specs for me?

That'll have me running a Holley 600 (http://holley.com/0-80592S.asp), Clifford intake, lump ports, 1.94I/1.50E valves, Long tube headers, Ross Pistons, and the 6-71 Blower. "
