Before I get flamed, I have searched and it didn't answer my questions...

I've got a Prelude SH as my daily driver. I would like to know, from people with similar HP figures, what exactly is needed to gain another 20-30 whp? With proper tuning, cams, I/H/E can this figure be reached? And no I don't want to turbo, I've already got two turbo cars, one of which is my dedicated "weekend warrior". I just want some more "go" from the Lude, I don't want to upset the balance too much.

My current setup is stock (except for Skunk2 valves...long story) with an AEM CAI. Stock exhaust from the header to the tailpipe. It has 112K miles on it with acceptable compression.

I know the figure can be reached, I guess what I'm looking for is a proven setup that will get me there. I have a wideband O2 sensor for tuning my Haltech-controlled RX and the expertise to tune with piggy-backs or standalones...I would like to avoid any guess work in component selections.

 

Intake, SMSP header. high flow cat, would be a GREAT start.

Don't waste your money on cam gears, cams, high flow fuel rail, etc.

I think a VTEC controller might help..but i have no idea what one does. LOL These should be what you need to get close to 200hp

 

Youll need cams, that smps or hytech header, intake and some form of fuel control/engine management.....200 whp hasnt been achieve by many people.....

 

I would think a CAI, SMSP header, hi flo cat, nice exhaust, dyno tuned vtec controller and cam gears with cams would get you close.

 

I'll probably need a fully built motor i.e. cams and piston. But you can some how crank out 190-200 horse power with bolt like Corey (Honda318dx) and (DR) have done.

 

Well, Im running injen shortram intake, Jg 4mm overbored throttlebody, anR/elite/prospeed headers, custom 2 1/2" piping to a trust muffler, Jun cams with valvetrain, fpr, and Hondata S200, ngk wires n plugs, on stock Jdm H22A block and head. This combo proved to be well over 200whp.

Okay, the dude that doesn't know what a VTEC controller is just told you to avoid cam gears so... GET EM!

I'd say AEM CAI, Mugen header, test pipe, mugen exhuast(it'll sound REALLY good!) cam gears, V-AFC, pulleys, get it all tuned really well and you should be close if your still not there Type-S valvetrain and cams I guarantee you'll peak 200whp!

 

How much is the SMSP header and what kind of gains does it give for a 5th gen base?

thanks~

 

read the smps topic....its informative

 

We hav'nt seen any dynos yet, but I'm thinkin around 15whp, they were going for around 1200 and I think he only made a few.

Well the first mistake you made was the Mugen exhaust just b/c its a Mugen exhaust doesn't mean its the best to achieve 200 horses. Trust me you'd be better off going with something that has less of a restrictive muffler. And while you might be close to 200 with the VAFC, the VAFC does not hold a consistant "tune" to it. i.e. you tuned it once on a DYNO and when you tuned it at that day it gave you the best result you could get given what the temp/humidity/ect was on that particular day. Going with a more consistant/reliable tuning computer would give you more consistant numbers on the DYNO since you're essentially replacing you're existing computer.

 

Here is the formula for 200 whp. Hytech header, skunk2 stage two cams, skunk2 valve springs, port and polish, cold air intake your choice (AEM), hondata s200 or s100 system, exhaust hi flow or gutted cat.
We built a prelude with this almost exact setup with out pistons and hytech header and got 192 whp dynoed by lawrence at Dyno Spot Racing in san Jose. It is definitely possible with the right tuning.

Read between the lines he didn't say he wanted some hard to manage super engine he just want a more fun daily driver. No the Mugen is not the best uber-performance exhuast. But, in his case it'd be about perfect. He just wants to tip 200whp not fly off the handle with custom one bend all Ti exhuast system. Sure the V-AFC isn't perfect nothing is, but, in this situtuation it will give all the adjustability he needs. Maybe spend an hour on the rolling road tuning it and his VTEC point, instead of 3 days and 18 hours making sure every square of the Hondata map is perfect.

So jun cams and valvetrain is stock
