whooo hooo, 200.4 hp!

Congrats Mike! This is definitely a big accomplishment! Put up a dyno sheet whenever you can.

A little thanks to Mike and Steppler for all the hard work on this one. I love these guys.

congrats mike. On your previous post about power in the DE. You mentioned that you were gonna try to get 180 whp with bolt ons. What cam are you gonna try to use with that setup?

What about using 11:1 - 12:1 pistons with the stock bore? Is it cost effective to stay with the stock bore, or is it cheaper to get larger 300zx pistons and enlarge the bore?

I'd imagine it would be easier to keep the stock piston size, but I could be mistaken.

Bigger means fresh bore, plus to get the proper lobe centers its best to get a custom piston with deeper valve relifes. Not having the right lobe centers is why we lost torque. 12:1 probably is not streetable on pump gas.

Mike

congrats and great job to you and everyone who is involved with the project, keep us updated and keep up the great work...

Today Clark went to work on the ECU and did some tuning for the C6M cams. The result is 200.4 whp @ 7800 rpm. I think this is perhaps the most powerful NA DE around that is well documented.

Tomarrow Clark is going to fiddle with the intake cam timing to try to get some of the torque lost by the big cams and next week we try Pete's new manifold. We will probably end up with a good solid 200's.

I think I'll proably end up going back to the C3's with the manifold to get midrange torque and more than 200 hp, unless the cam really responds to more advance. We can't run the optimal lobe centers because the stock and 300ZX pistons don't have enough piston to valve clearance so piston with deep valve relifes will proably produce more torque.

Mr Miko needs to get his big bore motor, going we are going to see 220 with that one.

Congrats Mr. Kojima,
Seems like your accomplishment is actually my goal to. Here in the Netherlands they do not tune like they do in the states. I am from Aruba and back home we are more American oriented when it comes to tune and cars. My goal is 200"Solid" Ponnies on my Sunny GTI SR20DE. I see now that's its possible but lots of work and testing should be put into it. My friends laughed at me when i told then that was my goal.

Well now i see its Possible. Congrats

jetpilot,

Down here(Greece) SR20DE tuning is unknown to everyone.
But 200 hp at the crank, is more than easy for the sr20de motor. i now make 182 with just a header, s4 cams, a home made CAI and only a 2'' exhaust.
If you buy jwt c2 or c3 cams with valve springs, a jwt Ecu with c2-c3 cam program, and a 60mm exhaust you are close to 200.

Is this supposed to be at the crank or wheels?

I would like to have the ponnies at the wheels

Deeeeamn. Man, you should make a straight drag car and take on them Honda boys hittn 9.99 all-motor. Or you know, at least make them look like we are coming up? Haha.

I herd Skunk2 plans to get back their title as fastest all-motor dragger with their new RSX race car. WHHHAAAAAAAATTTT! 9.99 and faster. Man...Respect.

Mike, do you think the sr20de could reach those levels of 370hp N/A like Honda does? I know you'd have to be big bore like they are. I believe it's the b18c turned into 2.2L. How do they get those numbers anyway? Aside from Higher CR, RaceGas what makes them so powerful? Bigger cams than the C6, more...other? I wish I could afford a project like that. Someday??

370hp N/A from a Honda? Have I been out of the all motor loop THAT long?

Just a little over a year ago, my friend JArrod Silvers was breaking ground with 250whp all motor.

If ever become a millionaire, im gonna buy a Primera race motor. I wonder what the hell those things are running? Anyways, good job mike, I would like to see that thing some time, I work just down the street from JWT. Man, you never seize to amaze us. Keep it up bro.

Yeah. Well it is a FULL race car. ITB's, no exhaust (header exits on the side) and the thing rev's to like 10k. geesh. but yeah...thats what the magazines have been saying. I don't pay much attention to drag racing unless they mention All-Motor.

I figured, Nissan built a 300hp N/A GTi-R motor, so I dont think building a Honda with .2L's more in displacement and 70hp isn't that bad. But, I can't remember if the GTi-R was increased either?

And, it has evolved pretty fast. In 98-99 Skunk2 was running 12.8 all-motor and people thought they were secretly using NOS? Haha. Then it just blew up from there. Then last year...uh, can't remember his name, but he broke the 10sec barrier with a 9.99 in his 02 civic w/ beefed up 2000 GSR motor. I had the article up a long time ago becuase everyone kept asking how to build a 300hp all-motor race car.

If we were millionare's, I doubt any of us would be buying anything Nissan . Well, I would just because I'm a loser and waste too much money . But IIRC they are runnin in the 200-250hp range? Prolly something else, I dunno, haven't read about them in like 6months. I forget.....

The Honda's are not making 370 whp but crank, the power level is in the low 300's at the wheels.

They usualy run methanol, up to 17:1 compression, up to 2.6 liters, deck plates, individual throttle body intakes, huge porting, huge cams and don't live that long.

Sure if you want a all motor class winner, it will take about 35k. Most of where the SR is lacking is in the cylinder head, half that cost will be in cylinder head development. Need a VE head with the VVL disabled, custom cam, mega flowed and rewelded and ported to an inch of its life. Give me the money and I'll do it.

Mike

the 300 hp GTIR motors are fully massaged race motors, running on race gas bla bla, super high comp, and with cams that would idle worse than the C5-C6 whatever they are. not streetable whatsoever, and they have Standalones, one thing that would help them get 300 hp easy. they actually make use of the full power range of the cams.
