which turbo..?

johndeere185 · 12-06-2006, 01:01 PM

My engine is built with 1000hp capable internals, custom grind cams and stage II heads, which turbo will give around 600hp and still have more in it? I heard an 88mm would be good, what about this: http://cgi.ebay.com/ebaymotors/INDUS...spagenameZWD7V
I've also heard a T76 would work, but i want opinions from people who have turbo experience.

GT42-76 will put you well over 600 and have lots of room left. I think its capable up around 900

Frank5L · 12-06-2006, 01:36 PM

Thats what I made 738rwhp/795rwtq with on my truck (GT42-76) with the stock longblock. For what you are wanting, thats the turbo I'd recommend.

what size pipe do you run off each header to the turbo?

That is a diesel turbo. There is a difference in the heat capability of the turbos for gas and diesel.

johndeere185 · 12-07-2006, 05:57 AM

what would that matter? Efficiency or something?

johndeere185 · 12-07-2006, 10:06 PM

How well would the T76GTS work?

You'll be very happy with any 76mm... even the funky old ones are capable of 900+ rwhp on medium-sized motors and they're very happy in the boost range we generally run (15-20 psi).

The GTS and GTSH are the cream of the crop.

Two things about diesel turbos - they're usually most efficient at higher boost levels (compare a T70, which is based on a diesel turbo, with a T76, which was designed from the get-go to be a gasoline turbo. The T70 reaches peak efficiency about 30 psi, the T76 about 16 psi), and they're usually not setup to take the heat of a gasoline engine.

As for pipe size, for 600 hp, whatever you can fit easily. I really, really think you're not looking for 600 hp. Think about what you'd like for 900 hp because that's likely to be where you'll end up.

johndeere185 · 12-10-2006, 08:13 PM

you think? I know the engine can handle 1000hp, but at what boost are we talking to get me at that hp level?

johndeere185 · 12-10-2006, 09:37 PM

anyone have a link to who sells the T76GTS? Id like to see some pictures and specs on it...

johndeere185 · 12-13-2006, 10:23 PM

does anyone sell piping kits with all the different bends to make headers and run the pipe to the turbo? Also, how much of a difference will you see if you run an intercooler vs just straight from the turbo to the tb? what type/size intercooler isnt restrictive at power above 600hp? My next question is about the intake. Im doing away with the factory air/water, im sure others have done this, how do you work around the built in intercooler? Would an aluminum intake off a regular f150 work with this kid of power?

pickrel performance on the pipes and polk performance on the best price on the turbo

johndeere185 · 12-15-2006, 09:48 PM

anyone?

johndeere185 · 12-27-2006, 07:22 PM

Where do you mount the 4 o2 sensors on the downpipe? Do you guys run straight 4" pipe or do you have a cat on there somewhere?
