92-95CIVIC SOHC TURBO
Trending Topics
We have installed a DRAG gen.III turbo kit for one of our staff members into a 94 civic Si hb. The car is stock and it ran 13.2 on 14 inch slicks, with some other mods it will run 12's no problem. boost is at 8 lb.
svps 12 sec hatch is running 10-12 at the most on a stock block. there is also other sohc turbo in the bay area from asr hitting 11.9 i think his best was but 12.0 all day on a stock block too.

there's a guy on this board named LiamXXX? that runs 14psi on his sohc daily, with NO internal modification. Says he only able to do this with careful tuning or something(?), don't know what careful tuning entails..but if he's telling the truth it's possible. But, I believe that figure is extremely hard to swallow, so don't expect anything over 10psi(max) unless you plan on modifing the internals.
I ran 10psi, on my Sohc, and killed my headgasket, and rings. at the time I was running rich, and had no detonation. I know some people have had success running that much boost on an SOHC, but I still feel the ringlands, and rods are simply too weak to with stand that much pressure.

stock headgasket is proven to be the best. IMO, and some will disagree with this. In order to run 10-11psi, w/ stock stuff on the D16....you should look into a more efficient fuel set up...such as stand alone, or Hondata, and using a J&S safeguard wouldn't hurt either. you need a Oops device...
Yes, that part is clear to me. J&S safeguard to monitor detonation as well more fuel delivery to prevent leaning out during boost, hence detonation. But, what about resleeving(?) or stronger/heavier rods? Would that allow thesohc to boost more..say 11-15psi?
yes, and no, with a sleeved block, and forged pistons/rods, you can run 20+ psi...BUT you will Definately need to go stand alone after 15psi, to protect your investment. FMU set ups usually crap out around 12psi.
I know alot of people who just shout out humbers like they're at the track or something...I would have to see some time slips for you guys running so called "12's" and "11's" on a crap motor with a turbo...the thing'll blow up before you made it half way...quit talking crap and blowing smoke up peoples asses and show us some time slips...and yes, people that go to the track know, time slips are available. Scan em and bring em on!

So with aftermarket pistons+rods and a blockguard..and also a dragIII kit..I can boost safely @14psi....can I run this setup w/out messing w/the head and run mid 12's

yeah i know i heard alot of people shout out #s too thats why you go out to the track. if your in ever in the bay area go out to a cmi event or test n tune at sac raceway and watch these guys hit those times. sorry i dont have my friends time slips.



Is there anywho have turboed there sohc vtec motors and running 12's daily driver.....I wanna build one...need some assistance w/steps..etc.
