I don't want to burst your buble mazdaspeed7. But a S4 w/ intake and full exhaust will have 182 stock hp + >59hp. That at least 241 hp at the FW. Yeah, I know the TII S4 weight more, but the hp difference is way too much. I don't think you can take a S4 w/ full exhaust and intake, but maybe hang with it is more realistic. Well, maybe you could win because you did not say an FCD. An S4 w/ full exhasut will hit fuel cut and should be slow as hell... Don't take it the wrong way, I think your car makes awesome power for an n/a (the second most I have seen), but I am realistic.

I ran into a couple of the 98' Vtec Prelude. I raced one when my car was bone stock and he only beat me cuz i had only driven a stick for 2 months and was shifting at 6k . Then i raced one later on, and i had Intake and no mufflers, and he had Intake, full exhaust and some other ****, and he only pulled a 1 foot on me to 60. So i can beleve mazdaspeed and everyone else who said they beat one.. And i have been dying to find one now and show them whats up! yea ive done a lot more since that race last year...

mazdaspeed how much does ur car way? mine w/o me weighs 2550.

 

2 months is not an excuse, i could drive stick well after a couple of months starting. Its not that hard to catch on.

 

Man, my 88 SE can beat a newer prelude, even if it has E/I/H cams, ignition, etc etc. All I've got is exhaust, intake, and ignition. Oh yeah...and a '91 GTX Jspec motor its all bolted up to...but thats besides the point

All joking aside, the newer preludes are quick, but an NA 7 should be able to beat them if they are modded right. The biggest thing I learned w/ NA to be a big help in performance is exhaust flow and fuel regulation...if you fine tune those two components, your good to go

 

lol, ya but against someone who has been driving a stick for a while? c'mon we all know it comes down to the driver.... So rotorman88 u got that beast running yet? damn im so jealous...

 

Did you just not read the part where I said "DEPENDING ON BOOST LEVEL"?!?!?!? Most people NEVER see a 60 hp gain from exhaust/intake. The only reason the hp increase is that big is boost creep. Running 10 PSI on an S4 TII with intake and exhaust will get you 180-185 RWHP, in a car that weighs 2880 lbs(if I remember correctly)

Im expecting 175 RWHP from my car with the new exhaust when I dyno again. That in a 2600 lb car WILL be faster than the above TII if the drivers are the same.

 

W/ full exhaust and intake in S4 TII it is damn near impossible to keep the boost down in my experience! I ported my wastegate huge-7psi unless it recieved more load- say over 150mph in 5th-then it creeps slowly to 12psi. You don't hear many NA guys talk about what their car does over 150mph JK

 

The number of n/a's that can even hit 150 is pretty small. I totally agree about the boost thing. Those wastegates are pathetically undersized.

 

And NAs tall MPG friendly 5th gear doesn't help...

 

No kidding. I shift at 8500-8700 rpm(8700 in 1st, 8500 in every other gear). I calculated my speed at the top of each gear, with my smaller than stock tires(diameter, at least). This is at 8500 rpm in each gear for my car with my tires(5th gear given I had the 500+ hp necessary to top it out)

1st 41.68 mph
2nd 72.36 mph
3rd 106.05 mph
4th 144.86 mph
5th 203.75 mph

N/A gearing SUCKS!!!!!!!! Oh well, Im getting new rear gears very soon, along the lines of 4.778-4.875

 

im still not inmpressed with the gs-r's,and how many fully dressed j-spec's do u think there are around here?

 

Ok guys...I'm talking about N/A. I have had a Turbo II with just intake, DP, exhaust, F-CON and it ran head to head with GS-T at stock boost. That GS-T ran 13.7 on track with drag radials. Of course he had them on when he raced me and I had my 335 BF Goodrich Comp T/A.

So I know what T2s are capable of. Now let's go back to N/A. They're just too damn heavy. My stock GTU weighed in at 3150 on a dyno. I need some major weight reduction and I'll challenge him again..

Jay Kim

 

Heavy??? My 86 na weighed 2450lbs (under 2600 stock) w/ full interior/ minor weight loss.

 

The 98 prelude in the original post features the honda H22A four cylinder VTEC pushing 222HP at the flywheel exactly, figure in 25-30 percent power loss through transfer to the wheels, a stock N/A(sad to say it) will get spanked.

 

Wrong...98 Honda Prelude with H22A has a power rating of 195HP to the at the crank and about 165 to the wheels. And here's a dyno of 99 Stock prelude to prove you wrong.

You beat me to it. US spec, 195 hp, J-specm 220 hp. Again, we got shafted on the engine.

 

I wish you lived closer, I'd race you when your car is done

Mine running 7 psi lost to a 12.70 Talon Tsi by a few carlengths. My wastegate is ported as big as it will go, and with no boost controller it will still creep to 11-12 in 4th and 5th on a cool day.

The only Prelude I ever beat in my NA was an Si, which have 160 hp, not 195

 

Not to dog on you, but you're forgetting something very important...

something TIIs have, but N/As dont...

something jimlab will have in abundance when (if!) he finishes his car...

TORQUE. My bone-stock 89 TII (~2900 lbs) put down 175/168 avg a few weeks ago. You may put down equivalent hp numbers, but I dunno about those torque digits. Keep in mind, too, that I was making (IIRC, the charts are at home) >150 lb-ft at ~2500 RPM, and it kept up all the way across the chart...

In any case, I'm sure your car is a screamer and I've heard of very-well modded N/As keeping up with stock-to-lightly modded TIIs before. But don't let your head get too big

I agree about the torque thing, but I will have either 4.778 or 4.875 ring and pinion soon. That will do a lot for making my powerband more usable, and would put my shift points at about the same speed as a TII, even though the rpm is over 1500 rpm higher at the shift point.

 

Hey! Cool. You're in Savanna. Will you be at the G-ville ECZA meet? I will, with my buddy and his georgous Blaze Red 87 TII - I'll be in the Noble White 89 TII.

4.778 or 4.875!!! Holy ring gears, Batman! That's some serious reduction! What's your (calculated) top speed with that setup?

Good luck,
Brandon

 

jspec GS-R's arent in US now are they? And lightly modded 90 CRX DX? Whats that putting about, maybe 105hp or so at flywheel stock? I doubt its lightly modded, if it can hang with any sort of running Turbo II in a race. And GS-R's aren't turbo are they.
I'm not saying hondas are all below average, but you're making them out to be more than they are.

 

bah, who cares. Honda's still make that silly bbbwwwwoooooonnnnggggg noise. =]

 

WHY ARE YOU GUYS WASTING YOUR TIME AND GAS ON HONDOHS AND **** LIKE THAT. I *** RAPED A 90 SUPRA TURBO,5.0 MUSTANG,ANY HONDA AND A LAMBORGINI KIT CAR WITH A SUPERCHARGED 3.8L ,AND I WASNT FULLY IN TO IT. WITH MY T2 BONE STOCK EXCEPT FOR GUTTING THE BULLSHIT PARTS AND A 3 '' FULL EXHAUST.

 

Who think they could beat this car:


That's CRVtec in a 92 honda civic hatch, fellas.

Jay Kim

 

pip hit the nail on the head with this one...n/a 7's are cool and all because they're still 7's but ya'll kinda need to remember that your not working with a whole lot and a 5th Gen Lude will seem powerful. But all that really means is you need to give you car a little bit more love in the mods department and go bakc out there and kick some honda a**.
