GEARS!!! If you have $250, buy some gears, at least 3.42's, preferrably 3.73's. If you are running even with your friend as of now, 3.73's will put you in front by at least 2-3 car lengths, and the car will be much more fun to drive. Also if you can get a little more $$, a 'Vette servo in the tranny would give quicker shifts = quicker car and increased tranny life.

well actually u r car has about 20 more hp and 5 ft/lbs of torque so u should have beat him nicely. The reason he can keep up is becouse he has a 5 spd, that gives him more hp to the ground, keeps him more in his power band and his car is also about 115 lbs lighter than urs. If u really wanna beat him i would recomend u regaining a little back pressure (so to speak) and a good set of gears. Try just a OEM cat or maybe even a high flow one. Gutting the cat doesnt really creat hp, its an old wives tale. I would than go with a posi unit and a set of gears. To have rear end gears done can be a bit pricey. It would be about 200 for someone to install them, about 200 for the gears and about 110 for the install kit. A posi unit can be purchased through SLP engineering for about 100$ becouse its a take off from the new ram airs.

Yeah, i would deffinetly reccomend gears and exaust. Best mods I ever done to my car. Little misc. mods help though too when they are put all together. If you need any help I made a site in my sig that tries to help first time 305 TBI guys to get started. Has some info on all the different mods that I have done so far and if they were worth it or not and has pics of them too. Hope it helps.
Also, another reason why u guys me be dead even is because ur torque ratings are so close. Torque is what really pushes the car when u race.

that would be true if the hp rateings where the same but there not. He should have had him by atleast 2 cars by 3rd gear. The 5 spd is what makes the difference. I guarantee it.

Dude, do u have to quote everything I f-cking say? And in a 1/4 mile race torque is very important, along with the 5-speed compared to the auto. If you were to try race him on the highway or something u would would smoke him because ur hp is higher than his and torque really isn't a factor there.

HEY! actually, torque is what figures hp. so you can never really say, hp is a factor and torque isnt or vice versa. Because, hp is a formula of torque @ rpm.

Dont you two get started again! It wastes my time deleting your damn posts.

ok eric that was messed up. I was simply trying to correct u for ur own benefit. U dont have to tear my ***** off. I was trying to forget this little "feud" but its gonna be hard with ur little smart *** comments.
WTF


SNFLU i told u i was gonna chill and im trying to, Infact im trying to forget n e thing ever happened to will u be kind enough to tell eric to do the same. IM trying to be somehwat respectful here.

ok so u want some cheap mods to take this kid out. First think i would recomend is a shift kit. They run for about 25$ for a decent one and could shave a good tenth or so. Do something about that gutted cat. Im serious i really hear its not good to do. Even a high flo cat isnt more than 100$. For 200$ u can pick up a nice intake that would give u a few tenths in the 1/4 as well. Depending on how much time u have i hear a great mod for auot cars is a torque converter. SOmething like a 2200 stall and they are good for about .2 to .4 in the 1/4 and will run about 180$. If u can do the work urself i would go with a shift kit, torque converter and maybe a deep pan to help keep the tranny cool.all together it would take that 250$ up perfectly IMO

U could go to a junkyard and get an axle from a v6 3rd gen..they came with 3.73's or 3.42 gear...except 91 -92..

and then put the slp posi in it(10 bolt)

remove the rubber seal under your hood next to window and put maybe a 1/2" or 1" piece of rubber or something near the back of hood (cheap cowl)
u could do the tbi spacer thing too

u could put some rubber hose around your intake fuel line(cooler fuel equals cooler intake air temps)

get rid of the cat(maybe u could use that as a scare tactic..cuz i got a FLOWBLOCKER too without a cat and its pretty loud)

tallboy has it right about the finding the gears. you can prolly find an ok posi too if your yard has some recent wrecks in it, i think it's any 88 and up 10 bolt chunk will work. you may want to check, they changed the spline somewhere along the way.then ya just need to buy the install kit.
go do all the ultimate tbi stuff, it's mostly free or at least really cheap. clean your car out completely and find any extra weight your are carrying around and ditch it.
shift the car your=self somewhere around 4800-5000 rpm. this will help keep the car in the power better than the 4500 that most of the stock trannies like to shift at.
just make sure you get a clean launch and you should kill him.

I wouldn't recommend a cheap shift kit. A lot of people complain about the 25.00 B&M shift kits saying that it ruined their transmissions. Everyone recommends TransGo and I use it and I haven't had any problems yet. I wouldn't recommend a deep pan, since I bought one from B&M and it was just to deep for the ones they offered for 700r4's. I measured it and it was only 1.5" from the ground to your tranny. So that would be torn off pretty quick. I would suggest a pollyurthane trans mount if u go with the shift kit which is 20 bucks and the transgo is I beilve 120.00? I bought mine for 85.00 brand new from someone in the classifieds. I agree with the TallBoy as well. That would be your best bet. Gutting the cat is a good idea if u have stock exaust. And a torque converter is a good idea too, but I never heard of a good converter for the 700r4 for 180 bucks. Usually they run from 250-300.00 bucks.

well it looks like you got 2 days. do intake for sure. and rearend will take you a night to do probably and a while to get out of a junkyarder. but its cold there and you dont wana be under a junkyard car this week. go with the intake, and i think youll be ok. You arent gona take him by carlengths or anything, but if you can get better traction, then you could win by a nice time gap. I wouldnt rush this, if you wana win big, dont race this weekend, race next weekend, with more mods. lay low for a while, dont tell him youve modded it, then take it to him at the track. maybe put some $$ down.

well i have to disagree about the cheaper shift kit. I mean im sure its not the best by no means but my friend had it installed in his 86 Z28 when he had 4.10 gears installed in it and he loves it. Hes had it in for about 6 months now and no problems and he really gives that car a work out when he drives it. I wouldnt know to much about the deep pan. The only time i ever heard of one is when eric tried selling me one and i know its supposed to keep ur tranny cooler. I did find the TCI saturday night special torque converter through summit for 189.99 so look through thier catolog. I wouldnt recomend n e mods that require the tranny to be removed with only 2 days left especially in winter weather. If u really want the most out of ur money just wait it out for a little while and find out what the best mod is to do for ur car. Gutting the cat is a very stupid idea. Its no good for performance nor is it good for the inviroment. On top of that he already said he has a full exahaust. Gutting the cat is even more dumb when u have a free flo exahaust.

Well I wouldn't recommend the B&M one atleast. I talked to a transmission specalist and he didn't recommend them either. He recommend transgo and most people on this board will too. Try looking in the archives for "shift kit" and see what comes up. BTW: the transgo comes with a installation video on how to install it. Oh and do u know how to drop a transmission completely? Cause u will have to know how if u want to install a torque converter. That is a pretty good deal on them Saturday night specials Mike talked about. Usually Torque conv. are around 300 for a custom one. Hey Mike, is that guy with the 86 Z the same guy u beat in a race when ur car was stock? And I guess I wouldn't recommend the cutting of the cat if u already have a full cat-back. Wouldn't do much.

Oh and make sure that ur plugs,wires,dist & rotor are lookin good before u take it to race him. A good tune up can free hp if they are in bad shape.
