Looking at buying a turbo...

[interex]

I'll be the first to admit I know nothing about turbochargers. I have been looking at different builds, and setups and looking at turbos here and there. I came across a brand new Garrett turbo that says A/R .65 .89 M-24 on it but I'm not too sure of what that means, or if it's a good size. How much horse power would this be good for? Would it work for my 2.3L stroker build?

Because a 500hp dsm is a beast. You start losing traction in an AWD at that point, and drivetrain issues become prevalent. I am there, and trust me, it's not that fun ironing out the kinks in your system. My trans is currently at shep's.

Well that's fine. I'm building my engine off a few other engines listed in the dyno sheets and I feel that it will save me time, and money to just do what I can to build a roughly 620hp engine than worry about a 400, or 500 hp engine and then try building up from there. Like I said after all my parts are bought and everything is assembled all I will need to do is tune.

I looked at IPT about a Performance Rebuild kit for my Automatic AWD. They have a kit for $429 and they want more than that for a high performance valve body. I think I can just do the valve body modifications myself and save me some money. I just might buy their kit and have a local transmission shop rebuild it for me. I live in a really big drag racing community and engine/transmission shops are around every corner.

Found this in an online ad... Is this a generic turbo or what??

P-Trim BIG T04E

This is a brand new turbo. This turbo is rated at 650 HP. This turbo is for someone that wants to have a really fast car. The compressor wheel that this turbo has is a GT40, the same compressor wheel that the new GT35R has. This turbo has the latest bolt down 360 degree thrust bearing design. This essential design ensures a long life, even under the most brutal racing conditions!!

Turbine specs:
-T3 round 6 bolt outlet turbine housing .83 A/R
-76 trim T350 turbine wheel (stage 5)

Compressor Specs:
-T04E housing 2.5" inlet 2.5" outlet
-56 trim GT40 compressor wheel 2.41/3.22 (61mm inducer)
-Flow 65lb/min
-Divided Turbo Flange

Uh, anything in a TO4E comp housing isn't going to be pushing that much air

Alright. As I said before I know nothing about turbos. I honestly have no idea what the turbine and housing numbers mean. I'm trying to learn, and keep on searching

Turbo Tech by Garrett. That ought to set you in the right direction.

 

[interex]

Right on. I'll check it out, thanks

This guy say's this is a "SBR" 60 trim. What can you tell me about it?

I still dont understand what the ".50" ".60" and ".70" mean, I don't know how to tell what is good, or bad. Or what is good for 600hp

I would need the Part number to give you the exact application and model number!
It looks like it is a GT40 style turbo off of an 8.0 Liter International!
It could work but as stated before it will be laggy!
also a the wastegate will be set at anywhere from 22 Psi - 26 Psi!!

just my $.02

If you would read what I posted you would understand. It is under turbo systems 102 section 2 .

 

[interex]

I read that page already. Does not mean I "understand" exactly how to meausre what the sizes mean, what is good and what is bad.

Big A/R's mean slower boost response and spool, but more high end power due to less back pressure.

Small A/R's mean a faster spool and boost response, but less power due to more back pressure. They also have a tendency to surge from such a quick spool. Surge is when the turbo is putting out more air then what your engine is taking in.

With a stroker engine, you can afford to go with a larger A/R on a mid frame turbo because the increased displacement will still spool the larger A/R. Or you can go with a larger turbo with a medium A/R. Or, if you plan to rev it pretty high, you can go with a big turbo and big A/R and it will act like a large turbo on a 2.0 engine. See what I'm getting at?

 

[interex]

Sort-of. My rev-limit is going to be between 8000 and 8500 RPM. I would like a turbo good for 600+ HP between 3800 and 8500 RPM. My head is a SBR Stage VI, Manley valve train, and Crower 280 cams with a 90mm throttle body.

 

[Turb07]

What about a Turbonetics T62-1, is that a good turbo for my stroker?

With what else?
P trim, Q trim or GTS?
.81 a/r .96 a/r?
need more information!
thanks

I found a garrett turbo, it say's it is this...

.50 AR COMPRESSOR
.70 AR TURBINE
COMPRESSOR WHEEL .57

He doesn't list which Garrett it is other than T3/T4. Says it is good for 650hp. Good, or not?
