91 camaro rs

i have a 91 camaro rs with a lo3(305tbi) mated to a 700r4 tranny. my bro's friend has a early 90 honda civic(ugly station wagon style) with a vtech engine do u think my car can take it? i do.

I had the same setup as you in my old 90RS, my friends honda like your buddys would allways pull me, not by much, but he would get me by a smidge, till i got hedders and cat back, then i got him by 2 cars, he did not have VTEC so he will prolly kill you till you get a gear, stall and some other major boltons, the lighter ones with VTEC only move the way they do because of the lack of weight if they dont have any mods, nitrous is a ****...

Adequately sized full exhaust from the head ports back (not TBI replacement stuff), 1.6:1 self aligning roller rockers, and computer tuning will put the VTec many car lengths behind you. There is 30-50 hp hiding in the L03 with just those things.

sounds like a d18 sohc vtec car.

...vtec advances timing at higher rpm, nitrous needs a timing retard to prevent detonation, how does that make it good for spray..?

brodyscamaro

Vtec refers to variable valve timing and electronic lift control...

You're thinking of ignition timing...

87TPI350KID

alright, i believe i mis-understood what vtec means, it's higher lift at higher rpm?

Just confused on how something mechanically controlled can be electronically controlled aswell?

brodyscamaro

I can't explain it as well as this, plus this is a much easier cop out

I would say if you are stock he will catch up to you..
you will kill him off the line, but he will gain..

Especially if he has ANYTHING done to it..
Put on some headers, and a catback and you'll run with him a ton better

I don't know what kind of Civic you're referring to, but I raced my buddy's '94 Civic Si hatch (D16 VTEC) with my LO3/700R4 RS, and I beat him by a few car lengths. All I really have is a 3'' exhaust, other than that it's mostly stock.

What happened to that Stu guy that used to be on here? He had all the import knowledge

rocluvr0013

he probably got tired of answering the same questions over and over again...

Either way an l03 vs civic would certainly be a slow race. So no matter what happens you both lose

rx7speed

mechanical advance, and EFI advances timing at higher rpms as well. so that would more or less eliminate any car from being able to use nitrous unless you are running a dizzy with locked timing or have static timing on your efi setup. that wouldn't be very good now for many cars would it

vtec also isn't for timing of the ignition but more for cam timing. it would be like running two cams in your car that at a specific rpm. you know one cam maybe something like 194*/194* .465/.465 and then another one at 230*/240* .490/.500 or something like that. more or less just allows for more lift and duration of the cam at higher rpms which with nitrous would decent enough I would think.
----------
think of your ignition. it has mechanical control by having the distributor rotate around to set off the ignition pulses then also has electronic control as well since the computer would be able to adjust the timing from the base timing that is setup.

there are many ways that electronic pieces can control something physical. selenoids, speakers, fuel injectors, electric motors and many many more take electronic input and convert it into mechanical action or even the other way around as in a alternator which takes mechanical motion and then turns it into electricity

rx7speed

which vtec engine? that's like saying what would win my rx7 vs a car that has a small block chevy in it? this vtec motor could be anything from an anemic pile of crap up to around I believe 190-200hp or so on a stock motor. which for that car would make it do fairly well as they weigh only around 1900-2100lbs depending on trim and options

If I remember correctly Honda didn't put VTEC in their cars until '95 unless is a Del Sol or a Prelude(93 i believe). Did he swap the engine? anyway, I don't know what you run in 1/4 w/ an auto but my L03 runs 15.9, nothing to brag about, but it should beat a 90 civic. is the honda an auto also? bone stock i think a 90 civic runs in the 17's but i may be wrong.

Mr.K

what kind of v tec motor does the guy have in his car and is it a wagovan youre talking about it being in? if he has a b series youll most likely lose if its a single cam youll get them.

V-tec started in 1989.It doesnt advance timing it just has another cam lobe that it switches to at a cetain rpm that is controlled by oil pressure,the newer style i-Vtec does advance and retard the timing but not the older type

rx7speed

just to further clarify it will advance or retard the valve timing not ignition timing. ignition timing is controlled by the ECU and has nothing to do with vtec

izcain

The first gen Vtec will control valve lift only. The newer IVtec controls not only cam timing and ignition timing but will also control duration of the camshafts as well.

Thanks for the extra help!!!!

Those things aren't that fast, I used to take my buddy Joel's '99 Civic Si in my LO3 Formula all the time, until he put nitros on it!
