Was searching for some info on this and would like to run a turbo but I want to understand what combo works best before I spend any money.

Correct me if I'm wrong on any of this. I'd like to run a T4 flanged 76mm on a 6.0L iron block for the 4.00 bore so I can run the L76/L92 combo. I was thinking of maybe running a 5.3 or 4.8 stock crank with forged pistons and H-beam rods. Will this work so far? I'm not to sure of what the CID would be after those cranks but according to my research running a 76mm turbo would work well with the smaller displacements. I know running pump gas isint the best for higher boost levels but I'd like to run 93 with alchohol injection. Please critique me and let me know if this will work and give me some input. TIA!

If you want the 4" bre of the 6.0 then use the stock crank and go 370 with a 76-88mm turbo.

Thanks! Will the turbo still be in its effective range on 370 cubes? I wouldnt mind doing that, just want to know what I'm getting into

I've heard 61-76 for stock displacement. Get the motor thought out and then give forced inductions a call. Dr.turbo will hook you up with the right size and ar for your setup.

Smaller motors will make progressively more power with a T4 flanged 76, down to at least <200 cid, BUT YOU HAVE TO RUN BIG BOOST NUMBERS TO SEE THE ADVANTAGE. So, I like your idea. A 4.8 crank would make it 328 cid or so, which should work well. Make the cubes small to get the pressure ratio's in check, then use good heads/cam to make it rev and make good power/psi boost.

The combo I am building right now is a 6.0 block, l92/l76 setup, 3.622 crank=370 with a 80gts front mount. Should make 800rwhp but not my main goal, I built it with all considerations in mind. Good Luck!

I'm now leaning in your direction, you building you hot side or buying it?

Its the real deal PTK kit, I got a great deal on it barely used. If I did it again I might have went with an OFI kit or Kentucky Turbo kit but mine should suffice for now anyways.

I really like the OFI kit, but not sure yet exactly what I'm going to do. I do know I'm tired of refilling bottles. If I did come upon a good deal like you did I'd probably ****** it up too.

Yup, the deal was outrageous and had many, many extras, I mean it was almost a COMPLETE kit, LOL The guy is going to help me install, should be cake since he's already done it. I was originally going with a D-1 but like you said hard to pass up a great deal and it should make 800rwhp on pump/meth

Sounds nice. You should be in the 9 second club then, as long as you can get it to hook.

I have a 76GTS from Forced Induction for sale. I bought it last year and never installed it. I changed my displacement plans and now have my 408 close to completion. I need a larger turbo for my 408 so I need to sell my 76GTS. PM me if you are interested. You can also ask Forced Induction about my turbo, they know of my situation.

4.8 crank = 3.27 Stroke x 4.0 Bore = 328.7cu.in. = 5387.03cu.cm. = 5.4L that terrorizes ford guys. Awesome if going 8.5:1 static 20PSI on race gas to 8,000RPM

5.3 crank is a 6.0 crank is a LS1 crank is a LS2 crank w/24x
3.622 Stroke x 4.0 Bore= 364.1cu.in.= 5966.92cu.cm.= 6.0L... I've heard of that somewhere? The way to go on pump gas. As for turbo size... I flunked that class

Yup, I'll be happy with 10's but once its dialed in and get the hang of it, that will he my long term goal. Its not the reason I built it but, heck why not if it can. Might have to put it on a diet this up coming winter for next year if I have to but won't go to extreme for a street car.

Good luck with your decision, as long as you research and take your time deciding it will all fall together and work out nicely. Try to think of it as a whole package and make it work for what you want to do. Powertrain, drivetrain, power adder, suspension, fuel system, etc, etc. Thats what I did. Heads, cam and intake are another huge one tha compliment the system.

I knew the LS1 and 6.0 cranks were the same stroke but didnt know the 5.3 was too. Thanks.
