her is the deal, i keep losing drag races to these damn preludes that are relitively stock, maybe an intake or something. my friend has a 92 prelude vtec with intake only and he beat me by a car length and yesterday i raced another one that looked stock and he beat me by two car lengths, whats the deal. i have an 86 gxl with a k&n cone filter, mindtrain header, bonez high flow cat, and apexi dunk cat back, and plugs and wires but i dont think that matters. should i be faster or is my car just slow. is this a common problem among N/A owners. after that happend i really thought long and hard about an atkinsrotary supercharger and i think im going to do it. no losing to hondas.

 

i think something is wrong with your car, a 92 vtec beating you by a car with your mods?? i think something is wrong with your car man

 

you should be killing them with that. get a compression test. your egine is probably just worn out. how many miles?

 

haha. well, That is what you get when you don't have a turbo. N/A rx7s are slow. period. Unless you got some major porting done. And if you are gonna argue with that, then you are stupid.

 

Uhh...no ma'am.

No offense, but that was kind of an ignorant thing to say. there are plenty of N/A FCs out there with power comparable to TIIs...

 

Well, maybe by today's standards they aren't that fast. But it took the sport compact market a long time to catch up to a 10 year old car. They were fast in their day and are still capable cars.

I do know of a few N/As that can keep up with stock TIIs. They have NO porting work done.

 

true true. =)

 

Hey stickgoat....is that a MAZDA mx-6 in that picture My gf owns one...and she's begging me to install an intake and exhaust..and...a body kit... but non-the-less...dude, i have a 91 na and i sometimes dont think its that fast, but after opening up the intake and putting an hks hiper exhaust on the back, once it hits 5500 rpm, that **** takes off like hell (compared to stock...) hell, today for the first time i hit 8000 rpm (usually go up to 7500...incase i slip the throttle and jump it up more) and when it hit 8000 it scared the crap outta me. i know its no tII...but its my first car and it sure as hell kicked the **** outta a 95 prelude by so far that i couldnt see him in my rear view...(hehe..on the go...twisty road .

i don't think that you should win anyway...

the 92-96 prelude vtec's were the faster ones (195 hp stock, i think) 6.5 0-60 and prob a low 15 in the 1/4. your car stock is prob mid 7 0-60, and 16 or so in the 1/4. so in a perfect world he has 50 more hp than you stock and both cars are prob similar in weight. i'm sure your mods definately help out...but i don't think intake and exhaust give 40 hp...

maybe if you take out some weight on the car you'll have a better shot.

my roomate has a slightly modded del sol vtec and i've seen him beat a stock T2 from a roll

 

How did we let this guy get a hold of an RX-7?

 

hahaha..i dunno, always downing on the N/As' :o..automatics'....and everything else...man, i'd hate to see this guy talk to a person who owned an eclipse RS...

 

At the dragstrip one time, I raced a 92 Prelude VTEC with intake and catback in my GXL. I had intake, header, full 2.5'' exhaust, no smog ****, or 6 ports. I still barely won. The bad part is that I know how to drive. I'd have to say that stock NA's are slow. Modded ones are decent

 

Actually a stock n/a is quite quick. It's not fast, but it's quick. Get rid of the cats and get an intake and it really comes to life, able to beat most of it's competition. Hell I don't have that many mods on my N/A but it's almost right on par with a TII. My dyno run in my sig was running with only 2 good spark plug wires. The other two were "limping" badly.

 

hey, i noticed you meantioned opening up the exhaust in front of the cat and including cat. i'd want a manifold/cat that would work on both na and tII. also, takin off the 2 precats...does that effect the emissions. i dont necessarily need them to be 'street legal' of course i dont want massive sound to attract cops, but i do need it to be able to pass emissions. what would you recommend since you did say it makes the biggest difference...i'd reccommend as close to 3" as possible seeing as my catback is 3", having a 2" cat and front of cat wouldnt use the full potential of my catback.

 

oops. I meant get rid of pre-cats. What I did was I gutted the 2 pre-cats then I replaced the main cat with a high-flow unit from CATCO. I doubt it would pass emissions, but my car is registered in South Carolina were there is no emmisions testing.

You won't find a manifold that would work on both n/a and TII . I chose to use a high-flow unit for the main cat instead of gutting it so my secondary ports would still work. But a header would produce some of the biggest gains. However I doubt you will pass emmisions.

 

Is there any rule saying we can ban people for being ignant?

 

oh, also...last time i was at bristol dragstrip i saw a 92-96 vtec lude run...

i'm guessing he had i-h-e. and 17 inch rims... he ran a 14.7

 

Even a RP or RB header wouldnt pass actual emissions, or the 'visual test' (or however you wanna call it). ive been thinking about replacing the cat very much. a CATCO $99 from summit is what im looking at for now, but if i put on the new high flow cat, i want to do it when i replace headers because it'll make it that much easier. oh well, ive got my springs to buy and put on along w/ the bushings.
In your opinion, what should i go for next since ive got a filter in there and an exhaust. i was thinkin elec. fan. but its winter...so i dunno, also a radiator, but..then again, i dont have heating problems and its winter...what to do..what to do..till summer...

 

So what do you have exactly? Intake and a muffler? Still have the stock exhaust manifold & all the cats? Any other mods?

 

92-95 i think prelude vtecs are pretty quick. ive seen em almost get high 14's stock. erik's right, you will need more than that to beat em.

 

hehe kewl nic It sounds like a 5th and 6th port problem to me. Do you feel that your car is starting to run out of power around 5,500 + K? You have a 86 witch uses back pressure to actuate the 5th and 6th ports. You put in a header and a hi-flow cat, those reduce the back pressure considerably. You should zip tie those puppy’s open and go take her out for a spin and see all the top end power you just gained. Then race that Honduhhh again and get some!! Peace

 

yeah, i have an intake filter, i believe the intake piping does the job enough aside from that peice in the L bend. i have a cat-back exhaust also. im looking for a street legal header and a highflow cat, as big as i can get up to 3" to fit on a 3" cat back w/ little restriction. If i have to get a few silencers along the exhaust then thats fine

 

Flame..not allowed

 

You have to have a cat?

 

16's aren't "quick". My modded out NA wasn't "quick". To me, "quick" doesn't start till at least low 14s...... I guess I've been around actual fast cars too long
