Ok, this weekend at the SERCA dyno day I redynoed my red turbo classic using VP C16 instead of C12 like last time and got 380 hp and 353 lb/ft of torque at 21 psi.

Now my car still sucks more than any of the other turbo SE-R's I helped build or tune but at least its not quite as embarrising as before.

Its amazing, the smoother combustion of C16 was good for 12 hp over the C12. It weas not detonating before, just sounded like rough combustion.

C16 truely kicks ass, its like turbo liquid crack.

Next is 3" downpipe, Tial wastegate, O2 induction manifold, 72 lb injectors, T350 turbine, JWT C2 cams. Hopefuly a lot more power.

Haha, good to hear. "C16 - It just sucks less."
I think a 3" downpipe and ported turbine housing make a bigger difference than headwork on these motors.

I guess we'll see how much of a difference these minor changes make soon enough.

Mike, are you who I think you are? If so........I'd like to talk to you a little bit about my engine.

Glad to hear it Mike. Are you using a .82 ported housing or a .63?
An off the shelf unported stock 0.82 T3 housing. I think porting and extrude honing are good for around 10-15 hp and 2-400 rpm quicker spool.

Are you referring to exhaust housing only or are you including the manifold?

Can't wait to try some of that "turbo liquid crack" when it's finished. :D

Mike, when you get the O2Induction manifold on, i think you will 400whp easy. I have ridden in Rob's with it on and it helped spool the turbo faster and the top end was sick. When we dynoed it it made like 51 peak hp overall. I sure you know that already though. Cant wait to put the prototype on my b14.

Mike do you know if it would be possible for Clarck at JWT to program an ecu for a short runner intake manifold (i.e. O2induction).
I don't think the short runner manifold will make any difference to the program, but I will test it for sure.

i KNOW this is an OLD post...but any updates from kojima? i'm looking into one of these manifolds, but i'd like to see some trustworthy dyno numbers first (their site numbers might not be the same boost settings, etc etc.

go over to sr20forum.com and see some of the older posts in there, or check www.se-r.net (the archives) there's a ton of good stuff in there too.

Mike will chime in I'm sure.

i actually started another post over there about those manifolds mike

did a lot of searching, and heard a lot of stuff about a poor idle control with these manifolds. supposedly, andreas copied o2's design for his own car, and modified the manifold slightly, and claims to have a great, strong idle. i'm already going to be running S4's, but combine that lopey of an idle with a poor idle, and i'd be stalling everywhere i went. ive already PMed andreas about what he did to modifiy the o2induction manifold, but no replies as of yet, and i brough kojima's old thread back to life in hopes he may reply to it and give me some solid info

here's hoping.

what kind of compression do you have? That's a lot of HP for a 4 banger. SO on race fuel, 360 hp and 330 Lb ft. ! I'm pretty impressed. when do you spool, or better yet, can you post a dyno sheet? I'd love to see what kind of flat HP and TQ you make (area under the curve)

thats not ALOT of hp, Trav4011 is in the process of building a massive turbo'd and nitrous-fed 700+whp beast.
"those little 4bangers" are quite powerful when built up properly.

300 is a daily driver lol

i expect on making WELL over 400whp with my setup when its done, possibly up to (or maybe past) 500whp on high boost and race gas.

by the way, check the dates, this is a VERY old post. i'm sure kojimas well above the 400whp mark now.

travis is in the process of doing a lot of things man. I wouldn't talk about what he's "in the process of doing" until it's finally complete...............

haha very true.
i just want to know more about these manifolds !

btw (chim)mike, i may not be building my engine after all. i got a VERY nice price from a pro engine builder. $4500 to build my whole motor (including parts and labor)...Wiseco 9:1's .020mm overbore, eagle rods, whole bottom end blueprinted and balanced, head ported and polished, Si valves, JWT S4 cams/springs/ti retainers, all ARP main bolts / headstuds...top quality everything.

plus, the guy warranties his work. if something fails because of his work (including defective parts)...he fixes it. just those parts MSRP are like $3500, plus the headwork is almost $600, plus blueprinting and assembly, and shipping, im VERY seriously considering this. it'd save me a lot of hassle, get me a certifably BUILT race engine, and get the stuff done that i CANT do myself (blueprinting/balancing, headwork, boring)

The car is mostly together but I have to fabricate a remote AAC/air regulator valve and install the 72 lb injectors.

My changes since before are O2 induction stage 2 manifold, Turbonetics ball bearingTO4E 60 trim and T350 76 trim turbine with extrude honed ported housings and wheels, a extrude honed turbonetics exhaust manifold and a full 3" downpipe.

It should make well over 450 hp.
