Newbie Turbo Questions

Could anyone explain the peformance differences between these 3 turbo set-ups?

Stock turbo with 1.0 turbine and ATS comp housing.

Van turbo with ATS comp housing

GTP38r


At most i might put mild injectors in at some point. trying to keep it mild since it's a PMR motor.

Van turbo with ATS comp housing. Van turbo has non wastedgated 1.15 exhaust housing for less backpressure. ATS ported compressor housing to stop surge.

GTP38r. Ball bearing center section, larger 1.0 exhaust housing, larger compressor wheel, ported compressor housing.

Re: Newbie Turbo Questions

Is there a big difference in power between the three?

Re: Newbie Turbo Questions

also the 38r is ball bearing and will support up to 40 psi of boost

Yes.. and a large price difference..

1.0 ex housing - $200-250 + $80 rebuild.. It flows well but with a chip you will run out of steam pretty quick.

Van Turbo - $400-600.. Flow more Air. Lower EGT's.. Mine is a bit smokey if I bog down.. it will billow smoke..

38R - $1500. Flows lotsa air and has the option to hit 475-500HP with supporting fuel and injection mods.. Does not smoke alot w/ proper tuning. The downside of this turbo is that it is pricey.

These turbos are great turbos for DD and people that do not plan on injector upgrades.

I may catch some crap for saying it but I am happy with my truck b/c it is a work truck. If I wanted to play and really get some nice numbers I would get the 38R.. but the sticker shock was too much for me.

And I got my van turbo w/ a ceramic coated exhaust housing for $430

Got any questions throw them out or PM me.

Good luck.

Andrew

I don't know about outlast. I've never blown a stock turbo up and we have been hauling heavy for almost a million miles on 3 trucks (combined miles)

I would say that a 38R would make the truck drive much nicer.

Now that I have my van turbo I am very happy. However if I did it again I would prob save up and go 38R.

To the OP.. a set of stage I injectors. (stock nozzles) and a 38R would be nice and you would be at 350-400hp w/ good tuning.

Those probably weren't "stock programming" and "light right foot" miles though.
