I have someone that can get me any turbo head unit from Precision Turbo for cost, and this new hook-up is the straw that broke the camels back... I've decided to commit to a turbo setup!

I need to choose a turbo that will work with all the PTK hot/cold parts, as thats the kit I will be using for this build. I see that I can get a 76GTS in varying combinations...

In GTQ or GTS trim... what the difference?

With housings that are...
On center .69 A/R
On center .85 A/R
Tangential .68 A/R
Tangential .81 A/R
Tangential .96 A/R

I assume the housings refer to them being "clocked" differently, which one work with the PTK kit?

And the A/R has to do with spool time, again which one? and why?

This kit will be going on a built 383, probably next year when I get done buying all the PTK parts. I know all about the need to build a complete car, you can't just go slapping on a turbo and expect nothing to break. I already have a Mcleod street twin, full bmr suspension, frame conectors (a Wolf 6-point cage to follow), Strange S-60 rearend with chrome-moly drive shaft, twin in-tank pumps (to be installed this winter), and a host of other supporting parts. About the last thing left on my list now is to build some power, and that's what I seek to do.

Just need a little help from the Pro's on the board...

 

You will need the GTS with a .96A/R and Tang. housing.

 

Dont listen to Jose, he doesnt have a clue.

What you need is a GTS with a tang. .96A/r housing

Wait a sec...


In all seriousness, Jose has alot of knowledge, especially with what works with the PTK kit.

 

I have a PT-76GTSHP: .96 A/R, Ported intake compressor housing.

 

Just for learning's sake would any of you mind explaining why that is the ideal housing to go with?

 

Cause that is the largest offered on a 76GTS unit.

Haha, well I hear ya, bigger is usually better. What about spool time? Is that based off of the 383, or would that housing be good for a 355 as well? What about heads, would it matter whether you had a huge set of AFR's (say 230cc) as opposed to ported stock castings?

Thanks,

Jeremy

 

You will see boost at around 3500-3800 on the street depending on the setup. You want a .96A/R with either cube. As for heads.....the larger the heads, the less boost you have to run to get to your target hp level.

 

Is 3500 max boost or just noticeable boost? It seems a little high for my liking.

 

max

 

Correct, that is max boost. You'll see positive boost well before 3500.
