interesting... i don't plan to drag race a lot, and not will full slicks. just thinking of building a turbo street car with A LOT of power... guess the tranny should do fine. i still might have it rebuilt before my serious engine mods... graemlins/bubbrubb.gif

btw, there's a used MAC H pipe (offroad, no cats) for sale in the garage sale section... http://www.columbusracing.com/ubb/ultimatebb.php?ubb=get_topic;f=7;t=001065

another '02 GT... what have you done to the car so far? any time slips?

is there anything you can really do to improve a manual transmission's life expectancy behind a high horsepower engine? any modifications you can make to increase the ammount of power it can withstand? or do you have to simply upgrade to a different (and stronger) transmission..? i'm just worried about the tremec 3650 gearbox in my mustang holding up when i start boosting the engine and adding better tires... clutch and flywheel choice have any impact on power capacity? those are easy to upgrade. i just want to know if i'm going to have to go hunting for a new tranny a year or two down the road... EDIT: btw, i'm looking for streetable solutions...

what exactly happened? just curious, anyone care to fill me in?

reliability is overrated... tongue.gif

that's what i've started doing. might not be so hard if i had a new shifter and didn't have to reach so far to hit those gears...

just curious, but how much is a complete 2JZ motor?

that was me... mustang trannies are finicky. mine sometimes doesn't like to go into reverse...

it's all in the tuning... if you're a bit conservative with your tuning and mantain the engine properly, it should hold up with a lot of horsepower... the only thing i'd really avoid with a factory shortblock is lots of revs...

here's my situation... i'm preparing a car to run in the NASA Vette Viper Challenge. the particular car i'm using, a 1985 vette, came with an automatic transmission (700R4) from the factory, and automatics are not legal in this series. anyone that knows these cars knows that manual transmission cars are somewhat rare, and the particular manual gearbox available in my car (4+3) is not a good transmission. however, the rules state that i am allowed to mix and match any OEM transmission parts available for my model (C4) of car, so i can use any transmission and parts available in the corvette from 1984 to 1996. my plan is to install a ZF 6 speed from one of the 1989 to 1996 cars. from what i've read, they hold up well under abuse, and are far less prone to problems than the 4+3 gearbox available in earlier cars, my only other transmission choice. gear ratios are roughly the same as the T56 6 speed you find in the new camaros and corvettes... does anyone know where i can find one of these transmissions? i plan to call some of the corvette salvage dealers, but i was curious if anyone had any ideas of where to find one. any information would be useful. any idea how much they cost used? i also need parts for the swap, such as the bellhousing, pedal assembly, linkage, etc. the flywheel and clutch are open, so i plan to track down new aftermarket parts for those. any recommendations for a clutch? the car will not be required to hold too much power, and is going to be used exclusively for road racing. if i remember correctly, the power to weight limit is 6.9 pounds per rear wheel horsepower for my class. the only restriction on the clutch is i have to retain the stock clutch diameter and configuration. multi disc clutches are legal. also, does anyone here on the board have experience in changing over an factory automatic car to a manual transmission. any help with the swap, even simple advice, would be greatly appreciated. i've never attempted anything like this before. thanks in advance...

just find an intake manifold for a non supercharged version of the engine, and plumb a pair of turbos. you prolly won't find a kit to do it, so be prepared to get creative. prolly not going to be cheap either, you'd be a lot better off to modify and tune what you have... if your budget's big enough, anything is possible...

you do realize this is a rental car, right?

on a rally car, flying through the dirt and mud? that might not be advisable... tongue.gif

mine does it getting on the gas at low speeds too, it's a bit of an on/off problem. some days the car feels pretty good, other days the car shutters REALLY bad. i dunno, but it honestly sounds like we have the same problem... oh well, good excuse to do a gear swap...

i've been having the exact same problems. i think my rear end is to blame... do you get a good clunk when changing gears too? i've done plenty of big burnouts myself... [ 13. January 2003, 04:35 PM: Message edited by: recklessOP ]

pretty nifty, i must say...

i'll be out at hooters tonight... not sure if i'll run the car though. the weather is getting ugly, and whatever my problem (be it the differential or something else) is, it seems to have been getting worse over the past few weeks. need to think about it... btw, what sort of problems exactly were you having with the rear end of your mustang?

sell it while it still runs...

thanks for all the ideas and help guys. narrowed the problem down a bit with some test driving this evening. the car seems twitchy at low speeds as you get on the gas, and also clunks a bit between gear shifts. seems more like the differential is to blame for the car's problems, more specifically the ring and pinion set, or so i think. i'm going to take it into the dealer, and get the rear gears changed and setup properly. i also hope to, with a little bargaining, get some 4.10s or 3.73s put in at the same time. the cost is the same, and ford stocks the different ratios for other cars. hopefully... new question, what ratio should i get? i'm going to run the stock 26 inch height tires, and the car will be driven frequently on the street, including the highway. autocross and open track events are also in this car's future. drag racing is a not a big concern. any thoughts? thanks...

wanna trade cars for a week?

that could certainly be. the car is being garaged for a while this winter, so i may just pull the clutch and flywheel out to have a look at them. not too difficult on these cars, and i could see where i stand... someone else back home thought my pressure plate might be on its way out. any thoughts on that? what would a failing pressure plate cause the car to do? thanks for all the help guys, i appreciate it!

the pedal setup is awful, and even though i've tried heel and toe downshifting, it won't work until i make some pedal adjustments. the gas pedal is just too low to really hit when you're into the brake pedal. i'm hoping to alleviate the situation before we head to mid-ohio this coming spring though. once i get this all sorted out, my driving under braking should smooth out nicely... new pedals are in the works as well, mine are too small, mounted too far apart, and too slippery. i've just got a million little projects lined up for this car don't i?

good idea. i'm tired of this self adjusting cable decided where it thinks the clutch should engage and disengage with regards to pedal travel. i've been worried the cable is causing problems with releasing the clutch. a new clutch quadrant and adjustable cable are in the works as well...

i'm being about as smooth as i possibly can in releasing the clutch, and more gas seems to help, but the cable seems have become a bit sticky, so maybe that's to blame. the throttle cable has gotten really bad as well, and i'm about to have both of them replaced. like i said, the car is a bit of a lemon... you're right about more gas helping, and that's what i've pretty much done to alleviate the problem. it's just something i notice in really slow stop and go driving, and it's not really a big deal... as far as downshifting to first, i had plans to autocross and open the track the car next spring, and any really tight cornering is going to require a downshift. maybe the gear whine is just a quirk with the new 3650 transmission. i'll just take it over to the dealer and see what they think... EDIT: btw, i haven't been downshifting to first at anything over 30 mph, and i rarely do it at all in day to day driving. just thought i'd throw that in there in case anyone out there thought i was jamming the shifter into first going down the freeway... i've got plans for stickier tires next summer, so a new clutch should be in the works anyways. i'm almost certain i've burned up the clutch to some extent with the racing this past summer... anyone else have any thoughts on the topic?
