who here has da fastest p5 n/a only.

If you N/A guys are interested please let me know if you would like a NEW intake manifold and TB we are working on. Thanks in advance:D

Me too dude, PM me if anything goes down with your project! I'll be happy to be a guinea pig since I'm not far from ya!

Karl-lohs!
 
intake manifold and tb - i'd be interested.....only if there is a decent amount of r&d - proof of testing (dyno runs), problems encountered with different sizes etc....if it's something that is very good, then count me in

later
 
I honestly don't mean this as a slam against anyone. Seriously.

But I do have to ask - what is the point of putting hundreds or thousands of dollars into an n/a P5? Even with cams, exhaust, pistons, headers, etc etc etc, what is the very BEST case scenario? MAYBE breaking 15 for a 1/4 mile? MAYBE a 7.5 sec 0-60? Or am I underestimating the possible performance gains?

I understand that it is fun/interesting to build up engines. I've done it myself on other cars. It's just that even with all those engine mods, the car isn't going to be fast. So, is it mostly just to make your P5 different or faster than other P5s?

Again, no offense to anyone. I love my P5!
 
if you're going to pose that question....

...why would anyone turbo a P5 when for the amount of money they spent to do it (and do it right) they could have bought a WRX and had AWD to go with it?

I love my P5...the way it is....stock.

couldn't have said it better...
 
i bet i am hitting high 14's with my p5 right now because i have beaten a prelude type sh which runs an average of 15.3 and two type-s rsx's which run anywhere from 14.6-15.2 also a gti vr6, but i don't know what they run. and if i got a light weight flywheel, a decent clutch, a head from sun performance, (i think thats the name) a computer to control it all, and some lighter wheels, and the throttle body and intake manifold from perf works, i very honestly think i could get my car into the very low 14's if not high 13's in the quarter mile
 
well i have to say that the best thing if u can affford it is this for an NA. Cams, manifold, header, high compression pistons, exhaust, intake. That alone should have u beatin msp's. My next round of mods is gonna get me close...but they are a secret. No NOs..no turbo. NA all the way....down with turbo lag
 
althought i will go turbo sometime in the future, i have to admit....gotta love n/a.

so perfworks...tell us about the intake manifold and throttle body...what have you done? what research and development have you done?

The stock manifold is very restrictive. Whats funny is that it is more restrictive once the secondary intake charge plates open. In theory it is supposed to make the runners longer and have the ability to capacitate more air charge thru the system. Unfortunatley when looking at the actual operation thru dynamic and static state it actually prevents better volumetric efficiency in my opinion by redirecting air flow thru a different path when you need it most. And that is at 4000rpm+ and open loop operation. The VICS plates open at 4750 rpm and the car will usually go into open loop depending on throttle position and load. It already has the velocity it needs to the port but unfortunatly the way the plenum and TB routing is designed it is not capable of breathing very well at the higher rpms. It was only meant to provide additional torque down low when velocity is key for optimal power. The throttle body is small in diameter also. Again the better an engine can process the air that it is given the more power you will make. Take a look at the honda manifolds and the way they are routed. You'll see that they can accomidate both low speed operation and high rpm flow thru the runners. The mazdaspeed cams would greatly benefit from the addition of a better manifold and throttle body. They have slightly increased duration so volumetric efficiency will be much higher in the lower to mid range rpm scale. It will reach peak efficiency much sooner in the rpm band and allow more HP potential.
Now in regards to the work we are doing, we are in the process of duplicating a design for forced induction that i have sketched. It will allow the use of additional injectors for increased fuel capacity to the system while keeping idle characteristics. From that design we will tune the intake runners for N/A operation also to provide low speed(RPM) velocity and the ability to flow enough CFM up top without choking the motor like the stock unit. When we get done with the prelimanary manifold we will of course show some baseline specs from the dyno across the rpm band and then specs from our new unit with TB and larger MAF. The tests will includeparts of the STOCK exhaust. The only differences will be the use of larger diameter midpiping inbetween the cats and cat back 2.5 inch exhaust with no resonator and high flow muffler.
Ill keep you guys updated. I wanted to get a feel of the support i would have if i were to market such a product and not just custom install. This will help bring down the cost.
:D

i'd like to find out wut the p5 with all motor is capable off... and like u said it aint worth fixin the engine cuz this car is not gonna get any faster and if it did it wont be reliable for street driving.
That is y i aint modifying my engine just lower the suspension then maybe rims.
 
The fastest All motor protege has 240HP and I mean All motor protege, the 2.0L FS-DE, not like "all OTHER motor" I like to call for honda swappers.
Of course, you will need a lot of stuff like standalone system, high compression pistons, cams, cam gears, header, exhaust...bla bla bla...
