well, i put my zc pistons and rods in my d16z6 last week, and it is peppy, not to mention reliable now that is basically rebuilt, but now it just feels like a b16 stock in my 91 hatch... i guess i want more power is what I am getting at, i love my motor, and refuse to go b-series for at least a few more years, if ever, i've had 2 already and severely disappointed ... i don't care about smoking everyone in the world, i do want to maintain having a license, and a car for that matter, but i love to pass that douche monkey that is creeping down the road like a dead chinese gramma... so what I am asking is, with the estimated 11 to 11.5:1 compression that I am most likely pushing right now, is it safe to have a jrsc at 7-8 lbs. of boost and expect reliability? the last thing i need is my rod busting thru my block and being late for my (hopefully hot) date...

 

Turbo FTW.

to the OP... are you sure of the compression specs?

on B series motors a bunch of guys are running 10.5-11.5 compression on 8-12 psi (some setups are intercooled and 2.0L too)

id say on 11:1 compression you'd be alright to run 6-8 psi on a tune. if it is indeed higher comp than that, run lower boost. you can adjust the m45 JRSCs all the way down to 4psi if you have to.

keep in mind that the more boost you run on the roots blowers, the more heat they generate. so, you'll be limited to higher octane gas and lower boost levels if you want to keep it reliable. heat=detonation although i suppose you could dump a lot of fuel at it to limit detonation. i personally like running colder plugs, higher octane fuel, and running it somewhat leaner... yes leaner than one would think. look into the ZEX plugs and some scaled DSM 450s.


if you run 4-6 psi on that engine setup, i dont see why you couldnt put out 175-185whp with the right intake, header, exhaust setup and tune.

on average the JRSC puts out 10 hp to the wheels per lb. of boost.

check out my profile... ive done a few JRSC setups and would love to do another. ive experimented with a bunch of different things but realized that the simpler the setup, the better. compression + boost and running it at the edge of detonation = power.

but for a stock/reliable/daily driver, just run lower boost levels. like i said, it'll put out like 50-60 additional whp to what you currently have. and the tq levels will be higher than all stock B series motors all the way down from idle to like 5k rpms. perfect for a daily.
