So i'm trading my head for a brand new sc51. Anyone know the specs on one of these or any information? I didn't see it listed on precisions website and my search on here came up blank.

Its for my b18a.

It's either an SC50 or SC61. I don't show an SC51.

 

must be an sc50. its .63 on the exhaust.

 

Like Ben said, it's either an SC61 or an SC50.

If it's an SC50, it's basically a Garrett Stage 3 turbine wheel and a Garrett T04E 50 trim compressor wheel. The SC50 is a badass turbo. I regret selling mine.

you can get the sc61 with a .63 exhaust fyi

 

The SC61 only omes with the .63 AR. They no longer make it with the .48 AR.

 

hmmm wonder if the guy ment sc61. Guess i'll find out when it gets here. i sent my payment today. I'll be happy either way. I just need boost and I hear precision is good.

 

Just found out it is indeed an sc50 with a .63
Hopefully i'll be happy. whats the spool gonna be like on my stock b18a?

 

It's gonna hit pretty late on a B18A. I'm guessing 5000 rpm. You might wanna switch housings. I know Precision will do it for you if you call them up and ask. I had a .48 a/r SC50 and they told me that switching to a .63 a/r at later date was no problem.

really that high? I really thought it would be lower. Don't people use these on d-series?

 

I think 5000 might be alittle high. I was thinking more along the lines of 4000

 

I've always been told people were hitting full boost around 3500-4000 rpms on stock b18a/b

5,000RPM isnt right. He should see Full Boost around 4,000RPM - 4500RPM depending upon his boost level, exhaust setup, etc. I have seen SC61S turbochargers making 16lbs @ 4700RPM - 4800RPM on stock head B18b engines.

 

so with a bigger exhast side, it will spool faster???

 

smaller=faster spool

 

3500 would be nice

 

So anyone actually know? i'll be able to tell you as soon as i get my car running.

 

You'll be the first to tell us. My guess is still 5000 rpm assuming it has a stage 3 turbine wheel. The stage 2 wheel was an option when I bought mine.

It might actually make boost sooner, but 5000 rpm is my guess as far as when it will be useable.

63 ar stage 3 on a stock LS would spool right around 3.3-3.5k and reach full around 4.6-4.8k. it doesn't take long once the turbo gets going...but there is some lag and you won't notice the power till a bit after 5k.

 

I get full boost around 4200 - 4500 rpm

Stock b18a
SC50 .63 hot

Did you get the stage 2 turbine or stage 3?

Good info. B18A might have a future in my CRX.

So what might i be able to expect with a .48 hot side?
