Yes we do complete installed 5 speed conversions and No we do not sell complete bolt-in kits. Anyone that will sell a complete bolt-in kit with a ready made driveshaft does not have a clue about 2002's and will cause you untold amounts of grief. Almost every one of these cars we do is different as far as driveshaft length goes. If the car has ever been hit, had a crossmember replaced or the Diff swapped, the driveshaft length will be altered. We will not make a driveshaft until we have a hard measurement on the vehicle with the trans and diff in place. A 1/8" mistake will cause the car to have chronic flex disc problems and driveline vibrations. For that reason we supply all the components needed to do the conversion but we need a measurement before we do a driveshaft.
It Is not that difficult a process to convert to 5 speed but it takes a fair amount of time and effort, not to mention money. The accepted method and what we do when we do them in-house is use a 1982 320I overdrive transmission. We usually use a 3.90:1 Limited slip diff. with this gearbox to give the best combination of freeway cruising and around town acceleration. If you want to know what it feels like as far as freeway rpm goes find a 320is and take it for a test drive. The other option is to leave the stock 3.64:1 gears or a 3.64:1 Limited Slip. This is great if you do mostly highway driving and low gear acceleration is of no great concern. The other way this gear combo works well is if you make lots of HP ( Turbo car or 160+hp ) and can pull the big gear on the freeway.
Here is a sample of 5th gear speeds @ 3000 rpm with a few popular tire combos vs. the 4 speed.
|5 speed||4 speed|
|3.90 and 205-60-13||63 mph||52 mph|
|3.90 and 195-50-15||63 mph||52 mph|
|3.64 and 205-60-13||68 mph||56 mph|
|3.90 and 195-60-14||65 mph||53 mph|
|3.90 and 185-70-13||65 mph||53 mph|
|3.64 and 195-60-14||69 mph||57 mph|
We always use good used 5 speed transmissions and Limited Slip Diffs. We can rebuild them but is expensive and not really worth it. All our good used gearboxes and diffs have a 90 day warranty and should give you years of good service. Rebuilding charges are in addition to the cost of a good used unit.
The limited slip diffs are all short nose 320I units and come with re-drilled axle flanges and axle spacers. This eliminates the need to change CV joints and keeps from overextending your stock CV's. They are shipped dry and include a tube of Posi. Additive.
All transmissions are shipped dry. We recommend filling before putting them in the car.
