Should i go with a SC61?
Currently i have a SC34 76 trim .60 .63 A/R but im not too sure if i want to use it or go with a SC61.
I want to be able to reach the high's 300 on pump gas and i dont know if it will take too much psi to reach that number.
Motor set-up include:
1st Gen b16a head
b18b1 block
81mm 9.5 wesico piston
Eagle rods
Arp Headstud
Turbo would be:
Topmount manifold
3 inch downpipe
2.5 intercooler piping
32x12x3 intercooler
thinking of going with 880cc precision since 750cc RC seem to lock up
I ran the sc34 at 16 psi with a stock b18b1 but im thinking of bringing it up to 20 psi depend on the power output and how it goes.
Should i stick with the SC34 or upgrade to a SC61, if i go with the SC61. It would one the one with an S cover

Re: Should i go with a SC61? (StolenTeg)
The SC61 will have a pretty terrible spool up time and I think it might be too much turbo for your goals. I say stick with what you got.

With your setup, 300whp is around 18-20psi for 400whp still be ok, but the turbo had to work harder to get there. If you going to rev higher, get the SC61. If you going to rev keep revving to minimum, go with the 50 trim(sc34). 50 trim will fatten up that midrange but being about 4% less efficent compared to the SC61 you will see a more significant torque drop off. sc61 is a monster from about 5500rpm to 9800.

I'm running a S62mm unit from forcedinduction/borg warner, and it kicks ***. Makes awesome low end power and tons of top end. I don't think you would be disappointed at all.

My sc61 hits full boost by 5000rpms and that's with a shitty turbo manifold. Spool is not terrible like you say it is, maybe on a d-series.

are you running a S256 borg if so isnt great how they beat down on the 60 series

No its the 62mm unit from Forced Inductions. Its a high pressure ratio wheel designed for smaller CI engines. Its an awesome piece and makes more power then the rest of the setups that have been comparable in size. I am thinking about getting them to build me a 66mm version of it.

Ah, you're referring to the Borg-Warner S362 turbocharger, in which Forced Inductions is a dealer. Yes, it does work well, but because of the very LARGE compressor cover (They come as a the backplate, and cartridge connected) fitment may be an issue.

Its a S62mm unit, not sure about the S362 jargon though. They CNC'ed everything for me and I watched as it was done...very cool BTW. I guess they are a distributor/engineering for Borg Warner since I saw alot of unfinished castings from BW. Guess they possibly machine for them.....either way I plan to swap to a 66mm version of this unit. They are working on the dual bearing versions for borg warner as well so I may wait.

You'll be waiting a while for the dual BB units. We're about 20 minutes from Borg-Warner, so we get a good beat as to when SOME of their timelines are.
Some of the V-bands are machined depending on the exhaust wheel used and its A/R size used. Some like the .83A/R used by the S366 are pre-casted. in either case, they do not use the standard 3" vband, and would use a special sized T-bolt v-band and adapter.

I'm running a sc61 on my d16z6. It hit's full boost around 5000 and pulls like a bitch 8500. Boost lag is not as bad as you think, Even on a d-series.

Re: Should i go with a SC61? (StolenTeg)
sleeved 1.9l b18c w/ stock itr head/ inline pro ss/ here w/ a sc6152e
20psi by 5000 or so rpm
387whp on mustang dyno on 92 degree day...
pulls like a m.....f..... from 5000 to 8500+!
I used to run a turbonetics 50 trim t3/t4 with a .48 ex. housing and that was maxed out around 18-19psi around 330whp on mustang dyno...
...the smaller turbo had a "sweet spot" between 3500 and 7000 but the sc61 absolutely destroys it up top. For a whp comparison, about 16-17psi on the small turbo = about 12psi on sc61.
for a stock sleeved motor a sc61 may be a bit overkill but will definitely be a lot of fun from 5k and up. good luck
also, if $ isnt a issue take a look at the borg worner s256... a similar car/setup to mine made similar power and spooled 1000 sooner with one, of course its the $ vs. performance where the sc61 shines

<---85mm B16a w/ SC6159 ported shroud peak 15psi at 5200rpm's. Not dyno'd but somewhere around 380-400hp. Def a blast to drive

Re: (TheShodan)
I saw the CHRA's they are using to design the DBB with. I know forcedinductions is working with timken and some other BB maufacture for the specs they want. So guess we'll see what turns up.
