So, I've been starting my SOHC Z6 build, stock block, eagle/wiseco setup 9.0:1, Studs, cometic gasket, 59300 w/springs and retainers, stock ports until I can afford a head to visit Brad and Howard at RLZ. I'm somewhat stumped as to what turbo to run at this point. I want to be able to make a little over 400 on race gas(with room to grow), somewhere around 350 on pump if possible. I'm hung between SC60 and SC61. I'd like to have the .63 housing, but I don't know if thats going to give up too much low end to have a car that might be fun to drive on the street. I've searched on here, had 4-5 results to SC61's on SOHC motors but, they all seem to be racecars making a peak power, not really making a power band. Anybody have any suggestions as to where i should go on this one? I know its somewhat of a broad question, and I'm sure theres more info out there if I looked around for hours. Anyone have a link or personal experience as far as SC60 or 61 on a mild built Z6? I'm open to suggestions to alternative turbo suggestions also that could make a decent power band but still hold up to the number on the top side.
'preiciate it...

those things are laggy enough on a stock gsr that moves more air than a D...

i can only imagine having a powerband from about 6-8k

go-autoworks ran one on his d16 setup and ended up with 284whp/212tq on only 10 psi.There's a graph on that page too.(granted his car is more of a race car that your not looking for but it gives you a graph to look and and see if the powerband is something you can live with)If you search sc61 on d-series.org and turbod16.com (when it's working right) there are more results.

thanks man, i appreciate that link. Anybody have any SC60 build links?

SC60s are a 60-1 compressor cover with a stage III exhaust wheel. They can work, but are rather a mismatch. I recommend more of a T3/T04E 60 trim turbocharger as opposed to an SC60 for the powerband that you're looking for.

does f22b1 motors count...

I have an sc61 on my motor and I make full boost just around 4200-4500 rpm roughly looking at datalogs... varies slightly depending on how much boost and what gear I am in. you just need to use a bigger sohc in your street car.

serious though. I would think an sc61 would be overkill for a z6 only looking to make 350-400whp. Depending on your budget maybe consider a 57 trim like the sc34 or if you have money to burn a gt30r. there is a semi-local d16 (mike93eh) making over 400whp on the sc34, he is on here as well. maybe he will see this thread and chime in.

lol, I'm pretty sure you've got quite a stroke on me. I can't imagine how a 22B pulls on a 61. I did a big 16G on a F22B and it was pretty hellacious- instant spool, tons of torque- ***** to the wall.

I've thought about the GT30 route. I'd really really love to get one, Its not nearly as easy to find them as GT35R's though.

Autoworks

I'll add more later, I caught the thread walking out the door. You can also search NewtDogs setup. I'd suggest a diff. turbo for our goal.

This is true. Like I said though, you don't have to go over $1000 just to get that powerband that you're looking for, really.

I've been doin a little research today in free time running in and out of the shop to the net. Found a bit of info on turboD16 but, its so hard to navigate through the rifraft of high school kids trying to build something from a probe turbo and DSM sidemount over there. good site though.

Need more input on the SC60 if possible...

The61 is nice, definately will pull like a train on the topend. It wasn't as "laggy" IMO as I anticipated. For the 400whp goal I would probably go SC50 .63, it just depends on how much further in whp you want to go further down the line. If $$ isn't a factor, I'd look into the S256 or S259.

autoworks, Thanks a lot for your post. I have been checking out your posts on turboD16. I want to make 400 for the time being, however, I do plan on expanding in the future and I don't want to drop the loot on a turbo that I'll have to drop from my setup when I step it up. I feel like I've almost brain washed myself into the SC61 because no matter what I find. I guess its because i haven't been able to really find any SC50 or 60 vids or numbers that are supporting my goals.

Autoworks

Here's an SC50 setup we did, tuned by Blueridge, they shouldn't be too far away from you.



There's plenty left in it, the car is running a Greddy FMIC, a better FMIC and more boost would definately make a sizeable increase.

You'll find alot of info on d-series.org as well.

I seem to have failed to mention I have been speaking with Bob from RCautoworks about having a Ramshorn and Downpipe built shortly. I think I'll be set on the intercooler, just mocked up my RevHard 31X12X3.5 FMIC on the front of the car Sunday and I expect it to be efficient to atleast 600, possibly more. I'm guessing the SC60 car was on pump gas also? Do you know a round-about of what Psi he was running his setup to make that power? I have been considering BRMS but, i've sent multiple cars i've put together for a few people to Howard at RLZ and never had a problem. I'm somewhat stuck between the two of them. From what I understand, Joeseph Davis is tuning for/at BRMS now?

Edit- saw the 20psi note. Does the car have a cam or any headwork?

I have the T3/T61 which is a touch smaller than the SC61, it uses the same compressor, but uses the Stage 3 turbine housing for a touch fast spool than the stage 5 SC61 turbine wheel. I've been in running it for the last 4 years on my Y8, hauls *** top end!

I feel like that is basicly exactly what i want, an SC61 with a bit smaller exhaust wheel. I really do not want to run a .48 housing on the back side and lose the torque and top end. I built a boosted ZC for a friend of mine last year on a .42/.48. Great street car but, I'd like to make atleast twice what that car made and my motor will be much more rev capable than his stock ZC. I realize the intake side on what I'm talking about is extremely larger than that setup so, i know that will obviously yield much greater power. I guess what I'm saying is I really want something to hit hard and pull strong but, at the same time, i don't want to leave a stop light and feel like I'm going to be waiting for the next stoplight to get moving. Are there any turbo's near identical to a SC61 minus the stage 5 wheel? Gahwd, i feel like a fuggin NOOOB!

Autoworks

Whatever you get, go with the .63 A/R at least.
The T3/T61 is a nice one as well, search ElSpool, he has info on his setup somewhere on here. The SC61 isn't as laggy as you would think.

I am 100% positive whatever i go with will be a .63a/r. The more i watch vids of the SC61 cars, the more I want one and the more I like the powerband. When the cars hook they fuggin leave. Greg, do you have any video's of your car with the SC61 besides on the dyno?

Unfortunately no, the one night we took it to the track w/ the camera, we made the test pass to make sure everything shifted smooth and it did. Next pass, nice burn out, broke the axle at the line . Towed it home, new upgrades going into a new chassis now

you got a new build thread for the new set up here or t-d16?

BiggieBert

goautoworks put a kit together for me and my Z6. Very similar setup to yours, oem HG, Crower stg2t. my turbo is a t3t4. I made 280whp at 18psi. stock t/b,i/m,ports. this all was with cyl4 piston rings not sealing.

Head side. no bueyno
My point is if those numbers are your goal, profesional head work is your friend with that d on your back. When I'm ready I'm sendin mine over to endyn(www.theoldone.com) they do work!

You wont be dissapointed with the RCauto setup. Here is a pic of mine

No, not yet. It will more than likely be on http://www.d-series.org first.

Hey man, haven't heard from you in a while. Nice numbers, too bad about the rings not sealing.

BiggieBert

Ya it sucks, I got the head off right now, block comin off today. tomorrow off to tha precision shop with my new vitara 75.5's. Even with my rings not sealing, I was still able to pull on a cobra and a CBR600(small town). Point being Autoworks does not disappoint.
