n/a tranny w boosted engine

[6 bolt dreams]

will an n/a tranny work with a 4g63t?? I ask because im swapping a 4g63t into my 93 gs but the engine is out of a 90. From what i understand the 1ga trannys weren't that good so if leaving the n/a tranny is worth it ill just sell the 90 tranny.

I had one in mine...I tried to break it. Eventually a bearing failed and it stripped gears. I belive thiws was from age not power.

Use the turbo one if you have it. Its geared taller, and it uses a bigger cheaper clutch

ya but arent 90 tranny non synchronized and isnt that bad???

and if the na tranny has shorted gears it will pick up quicker too the right

The AWD trans gearing is shorter ratio'd. As for the FWD gears, they are slightly taller on the top end. I believe that first and second gears on both trans are the same. Someone please correct me if I am wrong. And these are for the turbo'd FWD and AWD.

im going from a n/a to a boosted and there both fwd so.

The 90 tranny is syncronized. The only time it is better to have a later tranny, is to have a late 91-92 rebuilt, it accepts double synchro gearsets eaisier.

A turbo tranny will be better for a FWD because it is taller geared and will not blow off the tires as easily.

either tranny will work fine, if you run the n/t tranny you will need to get an upgraded n/t clutch.

now put your damn car together.

I knew a guy at a tranny shop who thought it was the funniest thing to drop the n/a tranny in his turbo car. (all 1g, i just don't remember what years)

He said it torque steered like the dickens, and that he ran through (which I don't' remember) the gears really fast.

He laughed, had fun with it, and then I don't know why, but it blew up after about a year. Probably because he beat the day lights out of it.
