That's the kind of header set up I've been looking for lol hook me up bro!!!
CulRidr's MP3 N/A build (~150whp goal)
- Thread starter CulRidr
- Start date
out of curiosity, how bit is the exhaust? 2.5in?
i'd be looking at a 2.5 if i were you - you seen to be on track to go over 150hp, and the extra flow capacity wouldn't go astray - especially if you decide later on to throw a small shot of giggle gas at the motor.

what are you doing manifold wise? 626? stock mp3?

at least port it a little and gasket match it

wouldn't turbulence counteract flow and velocity. Maybe turbulence around the injectors get a better air/fuel mixture but anywhere else it would hurt you no?
stock manifold flows like sh!t anyway dude...velocity is crap, flow is crap...anything you can do to help would be worthwhile
however you are already spending a bomb...leave the stock mani, if you don't hit your goal, move straight up to the 626 mani and port that...stock mani isn't worth it imho....cos no matter how you try, you can never polish a turd

unless after about a million years it turns into petrified poo...then you can polish it....(lol2)
^LOL...having no VTCS doesn't hurt mind you, but ya, I don't see a need to go nuts on the mani, I'm not gunning for the title, just a REALLY nice power bump. Ironically, my only bottleneck left in the intake-exhaust tip flow is the IM now...but I don't want to bother with the 626 to kill my low end torque.

ugh......loss down low is minimal compared to gain up
You're net gain in low end power will still be somewhat magnificiant.
higher compression+long headers+cams+cam gears (dialed in perfectly on the dyno) + engine management will make your bottom end better than stock, and midrange absolutely spastic. twiggy did the 626 mani on his ride, no appreciable decrease in response....worked a treat.
Of course, custom tuned length tunnel ram would be better
hehejust do it later if you don't hit the goal...personally, if you dont crack 150 hp i'll be a little shocked.

I'm curious to see what the MPI will do in terms of tuning. I'm seriously considering selling my ECU and MPI for roughly a total of 500-600USD to finance something else, whether it's an AEM FIC, Emanage, or of course what you'll recommend; a standalone Microtech...not sure I want to spend THAT kind of coin, and it might just be TOO much of a problem to get everything dialed in, especially if I decide to run in the winter, but ya...
The biggest thing about a piggyback is that I can easily tune it for cruising (closed loop), but tuning it for WOT is not really doable (in open loop) right? Do I have that right?
Thanks

depends on the computer and the tune.
Plenty of guys here make big numbers on piggybacks...they can be a bit of a headache to get to play nice with the stock computer...
niki and sleepy did some tricky things with switching o2 sensors off to force it into open loop if memory serves....(ecu stops seeing o2 references, falls back to the fixed map, which is then pumped up by the piggyback computer)....no doubt you'll have lots of fun trying to get it all sorted ... but the same is true of stand alones... 2 years and hours of work and my microtech setup still isn't _exactly_ right.
as for stand alone, MT is cheap - but for a little more money, the new Haltech Platinum Sport 1000 looks the goods (at least on paper)
