    indeed... forced induction would be a higher price, but the return value would be MUCH nicer.

    FI would lead the way for a large smile on your face :) :) :)

    Yes it is expensive, but with the correct FI you'll never know why you didn't do it before.

    3 Major upgrades

    Hey what up guys, I just posted a thread on track/race about my first 1/4 mile run. It was a 17.9 @86pmh. Im driving a 99 CE, auto w/SRI and an exhaust. There were a few things I had in mind for the last few months, and after running my car for the first time, Im determined to live my dreams. I was thinking...

    1. Reworked torque converter
    2. Alluminum flywheel
    3. alluminum underdrive pulleys.

    Will these 3 major upgrades be highly beneficial to my 1/4 mile time or am i just wasting my money? I was going to try and get these three upgrades first, and then go to running boost off of my car. All oppinions and info is appreciated.

    you don't have a flywheel to swap out for an aluminum one..... the torque convertor bolts to a flexplate... which is already a very light unit......

    I think you're wasting your money. Boost it instead. :D

    agreed. with a slowtomatic, your best bet is boost of some sort.

    hey vortex, why do you say that it wouldn't happen? are you saying my stock internals couldnt handle it or what? I actually talked to one of my local shops today and they said that they could do a 5 speed swap for 1500-2000. It just seems like a lot... I know I have to spend a lot of money on my car to give it some go, but I figure it like this:
    - tranny swap: 1700
    - turbo : 2500

    =4200

    my car cost me 8000! both the turbo and the tranny swap adds up to more than half the cost of the car. My main question is, if I installed a high stall torque converter, dropped a custom turbocharger in my car, with keeping the auto trans, what would I be expecting to run in the 1/4mile? sorry for the ignorance :)

    so you guys just think go for Forced induction? is nitrous harsh on an engine? I plan on a turbo anyways, but i dont have 2500 to just spend. nitrous seems like the way to go, but ive never been in a car with spray. Whats it like? and how many seconds do you think it would shave off my 1/4mile time?

    1. do a swap. the money you will spend on an upgraded torque converter could be better spent on a 5 speed.
    2.pulleys don't do shit.
    3.i/h/e
    4. 30 shot of nos on a stock motor will do u just fine. and u will be around the low 16s with that.

    don't waste your time on the auto unless you're prepared to spend a LOT of money... well you can spend a lot of money on the manual too, but you're talkin about thinkin you'll turbo for 2500 - not going to happen. Not knockin, just sayin - if you really want to build a Corolla, be prepared to spend some serious dough - otherwise... :eek:

    No I'm saying that in order to turbo your car right, you're not going to get it for 2500. Plain and simple. Be prepared to spend NO less than 3500. If not, be prepared for whatever problems you may have, because there will be plenty.

    As for the 1/4 time with the auto... I'd say run no more than 9.5 psi (altho some of us have done higher on autos) - look for around 14-15 seconds. (however its possible to maybe pull off a high 13 as long as you're not losing your ass with that auto tranny eating up your torque) - it also depends a little on vehicle weight etc too.... just a rough estimate and is by no means a solide proven number.

    where does the 1zz make its peak torque???
    well where ever it makes it, get the stall a few hundred RPMs under. that way u skip the low power and jump to where it makes the most power. im sure with a proper stall u would be quicker than a 5 speed

    aight, im back to the point where i have no idea what im going to do. i would love to keep my car and try to give it as much go as possible. Is it true that a 5speed swap would only shave like not even a whole second off my 1/4 mile time? Im really considering just installing a 35-50 shot of nitrous... it seems logical.

    that's in debate...

    it's mostly the driver. Perfect example. A professional driver (the person who does these tests for magazines) is able to make the corolla (1998) do these stats:

    0-60 - 8.46s
    1/4 - 16.61 @ 85mph
    60-0 in 164ft

    I'd bet anything 95% of the drivers out there would be lucky to get 17-18 seconds with the exact same car on the exact same test track.

    Just offering up my opinion after reading this whole discussion. From experience with 3 boosted cars, all totally different. FI is what you should do. Leave it an automaic. If you are really going for power and a drag car automatics are better. not as much fun, and I don't neccessarly agree but that is what they say. I think it would be a waste of money. Just save for the boost. If your worried about too much money and mods after boosting go with a supercharger instead of a turbo. Hope I helped Thanks!! Good Luck with whatever you do!!

    see getting a supercharger would be nice, but they dont make one for my year. the only FI i could go with is a custom one. Im pretty sure im going for a 3200rpm stall torque converter and eventually a 50 shot of nitrous. the way things look right now, itll probably only be when i get my tax return!
