man, mike kojima did a FWD DE to over 480whp over 5 years ago - i posted links to it in teh DE - DET threads here, se-r.net has links to it.
and 690whp i think is the record on a stock block SR20DET with jsut bolt ons, NO forged internals.

TriniGT · Postby **TriniGT** » February 16th, 2007, 10:22 am

I know but this is a stock reconditioned JDM block with cams only. I think it's pretty nice for a low budget project.

The question is how long will it last.

aren't sr20de's ludicrously over-built?

Bezman · Postby **Bezman** » February 26th, 2007, 10:09 am

at the 650+ tune, last i read one lasted over a year, then blew a ring land, but they street drove, dynoed and drag raced it, and i think it finally let go cause of boost creep (too small a wastegate), causing over boosting and lean conditions at high boost/revs, absolutely not bad at ALLL, especially seeing you can just pick up another stock block SR (for cheaper than forged internals) and sell off the unused bits and bolt on your turbo/fueling/EMS system and a lil tuning and be right back on track to over 600/400+ whp

nuff said there RS200. Tuining with stock internals on an SR is amazing.

The SR20det has one of the weakest heads out there.

Postby **dry** » February 26th, 2007, 2:33 pm

what you mean weak? as in flow? i'll agree with you on that for sure. with stock cams, you'd be hard pressed to get over 350whp, no matter how much boost you run. it just can't do more than that.

with cams and an intake manifold, it's a different story.

TriniGT · Postby **TriniGT** » February 26th, 2007, 2:35 pm

Yeah but with some head work, wonders. Intake mani, Solid lifters/lash kit, Comp springs and retainers, solid type cams, port and polish, HIGH RPM here we come, 9000rpm easy.

Hopefully I can display this when project done, for now I keeping meh mouth shut.

After installing cams would the engine be stock still ? also dont forget about those rockers.

Postby **dry** » February 26th, 2007, 2:53 pm

I find for a man that real like a sr20 you is fight it dong. From the time you raise boost, it's not stock. We talking about the bottom end here anyway. You don't even have to separate the head and block to get to 500whp. Stock pistons, crank, rods.

The rockers like to go out now and then, but only above 8000rpm and from bouncing on the limiter. I've revved to 8000 without throwing rockers. I think if I had hit the limiter, I woulda be looking for rocker bits.

there's an interesting discussion in the honda specific forum on engine spd and rod ratio... with the sr20's comparitively low rod ratio, maybe shifting at 9krpm often isn't a good idea, even with a valve train that'll support it...
