I ordered a turbo from a company off here(will not name). It was suppose to be a sc61 with the works(stage 5 wheel, custom exhaust plate,..etc). I just looked at it the other day and it dose not say precision on it. They said they were waiting on it for a month from precision because it was custom. I got it now and it says garrett on it. ??

You probably got Garrett's 4-bolt turbine housing instead of Precision's 5-bolt turbine housing. Is there scribing on the compressor outlet?



I have a better picture of the scribing if needed.

integramic

yes there is.

alpha

What are the numbers? Is it a 4-bolt or 5-bolt turbine housing?

integramic

It is a four bolt.

alpha

That's why it says Garrett. Precision uses Garrett 4-bolt turbine housings.

integramic

says it on the inlet side also...

How can I tell if the compressor wheels are right??

alpha

What does the scribing say on the compressor outlet? Measure the compressor wheel inducer and exducer.

let me jump in here.. what is the inducer and exducer on turbos?? ive been tryin to find out the exact model of my precision turbo and i cant.. i wish i understand all the real technicals on the turbo sizes and things like.. can anyone explain please??

alpha

I mean what does the scribing on the compressor outlet say? You could also measure the compressor wheel inducer and exducer.

This is an example of Precision's scribing

alpha

Measure the base of the wheel (compressor=exducer, turbine=inducer) and the tip of the wheel (compressor=inducer, turbine=exducer).

compressor wheel -
(inducer x inducer) / (exducer x exducer) (100)

turbine wheel -
(exducer x exducer) / (inducer x inducer) (100)



A: Turbine wheel, B: Bearing and seal, C: Turbo shaft, D: Exhaust turbine housing, E: Backplate, F: Compressor wheel, G: Compressor housing, H: Bearing housing, I: Inducer bore, J: Exducer bore

With Precision turbochargers you can identify them with the scribing. The only way the scribing would be wrong is if the individual assembling the turbocharger at Precision made a mistake.

integramic

that is what I have on mine...6152E

alpha

6152E is an SC61 with a T350 76 trim turbine wheel and a T04E compressor cover

integramic

Is that the best I can get other then the sc63?

alpha

Allot of tuners on here seem to prefer the SC61E over the SC63E. The only other turbocharger (within that price range) I would take over that is the non ball bearing Precision GT35E.

lol.. im happy i know what turbo model it is now.. turbo was bought from inline pro and i forgot...

how much better would an SC61 do over my SC44??? should i look into upgrading?

The SC44 is a good turbo. If I am not mistaken they use it with a .48AR housing? For the most part people have turbos that can already make 500whp but still want a SC61.

yes it has a .48 a/r housing... whats the a/r ??? on precisions site it says i can also be a .63 would that have been a better turbo??

im pretty sure im happy w/ this turbo for now.. once i get it dyno tuned, ill be even happier

sorry its late and another shitty saturday night (i hate rain) so im getting a crash course on definations of turbos..

Arturbo

The SC44 with a .48AR works really good together on a street car. Makes things really fun...

i traded my sc61 for a sc44 and have no regrets. afterall, how can i be disappointed with quicker spool?
