My setup:

b16a (Stock)
Rev Hard Turbular non-AC Manifold
Rev Hard Intercooler 32x8x3.5
Tial 35mm
2.5" downpipe, testpipe, and catback.
Rc 440's
Hondata

My Goal for now is 275-280whp.
My Goal after the sleeves, rods, pistons is 375whp.

What turbo will suit me best now and later.

The Turbo I have now is next to the Red Arrow in the picture.

Rod at precision said it's good for 380whp. But is willing to swap what ever turbo I want from this list.


Or I stick with what I have.

Thanks guys.

 

My goals are about the same as yours for my b18b...Art recommends I get the sc34, not sure which one.

 

the sc50 is a great turbo. especially if its a daily driver. you can go wrong with it other than that if you decide you want 450-500 hp youll need to buy another turbo again.I would go with the .63 if i were you. the .48 rips tires badly.

 

keep the turbo and swap the housing to a .63a/r you will reach your goal w/ that turbo

 

Rod from Precision said the .48 will make 380whp

 

It will make 380 with a .48 but its going to build boost way too fast for the street. my opinion is the .63.

 

I understand, lots of tire smoke.

 

I really like the SC44 w/ .63ar. its a 6 blade 60trim wheel so its really efficient and should flow a good bit more air then the 50trim. the .63ar will help u support ur final horsepower goal better too. .63ar isnt laggy at all.

good luck.

Thanks.

 

(hope you dont mind if i jump in on your thread)

... but, what sc-series turbo would you guys recommend for a semi-built gsr (je pistons, eagle rods, stock sleeves)?... goals are 300-350 hp, quick spool, decent top end, and high efficiency... lemme know... thanks...

 

SC50 63 a/r.

art

 

how about for a stock gsr motor boostin 8psi?

 

I actually have that SAME turbo for sale... except its ball bearing and has a polished compressor housing. im asking 750 +shipping for it. it has no shaft play whatsoever and has been taken very good care of with only 2000 miles on it. Spool up on this turbo is really fast, trust me you'll love it. The only reason im selling it is because im going with a t4 monster ***** turbo. t04e 50comp trim .48ar t3 housing. turbonetics told me it was good for 400hp.

Rev Hard said they would swap the .48 with the .63 if I don't likw it.

Should I try the .48 first?

 

If they will take it back used go for it. But I doubt if you don’t like the .48 and get the 63 and still don’t like it they will give you back a .48.

 

Well I don't think I can get the .48 back if I don't like the .63 . .

 

how much do the t4 60-1 .70ar ptrim precisions run?

 

i have a hard time understanding the part #s they have also. Try giving Rod a call, i called him and he took the time to answer all my questions and to try and make a turbo that will do what i need it to do.

 

Where'd you find that? Sorry I was looking for that exact thing earlier today, and I couldn't find it anywhere.

 

Folks,
Remeber that the horsepower figures for these turbos is figured (rather conservatively) at the crank. Deduct about 15% of that for frictional horsepower losses through the drivetrain.

I also agree that a .48 A?R ratio is too quick for most. Great for stoplight to stoplight racing, yes, but with that comes potential traction problems and a lack of topend power.

There are a number of other options. You can go with either a 4 or 5-bolt turbine housing (T-31 high flow with a T3 flange) or with a T04E or T04S compressor cover. The T04E might fit in some engine bays better, but the T04S reportedly flows 10% better. We probably need to do a dyno test on these things some day.

Feel free to give me a call anytime if I can answer any questions anytime M-F 8 to 5 Central Standard Time.

... can you do us a favor and give some max hp figures for the sc-series turbos?... for example:

sc50 - 380 hp
sc32 - 400 hp
sc34 - 420 hp
sc44 - ...
sc60 - ...
sc51 - ...
sc52 - ...
sc53 - ...
sc54 - ...
sc61 - ... etc

... i think something like this would be helpful to everyone since most of the compressor maps arent available...

thanks...

 

I'll go ahead and post this again.

SC50-425hp
SC32-480hp
SC34-545hp
SC44-565hp
SC60-580hp
SC51-585hp
SC52-600hp
SC53-610hp
SC54-620hp

 

Thanks Art. I don't think I need a SC44.

 

When would say, .45bar be hit on a gsr(roughly, 3" exh, 2.5"dp) fir these 4, and would they be dissapointing at that boost level? How much block shaving too, with maxrev mani/dp? dont want to take away from your thread, sorry.
SC50-425hp
SC32-480hp
