i have a 93 sohc. i want it upgraded since its gunna be ripped out, it sticks in gear and is hard to put in and out, then it doesnt come out unless i hit it out. what transmission can i use and what do i need with it? i would like one from a bp, but i cant find any 90-94 protege 1.8's and i found only one escort gt but it was junk.

you can put a g-series trans from a Bp on a sohc but u'll have to modify the bp halfshaft to make it all work.. the bp flywheel will bolt up to the sohc.

im still thinking if i should use a f-series or g-series trans for my boosted sohc.. ya u read right..

can i use it out of a 99 protege with a 1.8? if i get the axles and all that....but what kind of mods do i need to make?

just the half shaft is what needs to be modified..

as for the 99 protege will im clueless on the answer on that.

ok im going to get the transmission out of a escort gt, hopefully the flywheel and axles and mount i can get all with it.

how do you mean modify? im very limited to tools.

modifying the bp half shaft was done by a local fabricater where i live at.. i
had get the half shaft cut in two where the the 3 bolt holes are at and slide it back to where the 3 bolt holes line up to the 3 bolt holes on the sohc when i got that done i had the 2 peice tag weld and them weld all around.. iron is really had to weld.. but that what i had done to get the bp half shaft to work on the sohc..

u know that u will need the BP

g-series trans
flywheel and clutch
top trans mount
slave cly.
half shaft (which u'll need to modify to work on a sohc)
both axles

ur sohc front and rear trans mounts will work on a g-series. but if ur are shot then ur better off getteing the mounts from the g-series same as f-series trans mounts front and rear i mean.

the sohc block is a shorter block than the BP.. common sence but hey go find out the hard.. i don't know what im talking about...

and how many guys have used a g-series trans on a sohc.. u find one u let me know.!!!!!!!!!!!!

i just havent heard about it before when being discussed.

mazdamx3sohc · Post by **mazdamx3sohc** » November 17th, 2007, 6:34 pm

i got the transmission today, it needs axles and the clutch disc is safe to say, gone....he clipped off all the wiring so i have the plugs. the mounts and everything look worn...o well...im gunna rebuild this thing, clean it and paint it before it goes back in..

HERES THE QUESTION..
i need a new clutch disc, the pressure plate and bearings are all in great shape, i also got the flywheel and that is in good shape too....when i buy the new clutch disc, does it have to be spefically oem replacement???? cuz i want a performance disc if i can use it with a oem style clutch kit.

anybody?

Limegreen mx-3 · Post by **Limegreen mx-3** » November 18th, 2007, 3:22 pm

u can use a aftermarket disc but its not going to help u.. being a stock pressure plate.

what makes a clutch a clutch is the pressure plate..

in my f-series trans i used a 1.6 miata flywheel and ACT extreme pressure but since the miata disc the spline was to large for the trans shaft.

i was force to use a 1.6 dohc disc clutch with the miata clutch.. it help up to my 18psi untill i upgraged..

but to be truthfull u can buy just a stock disc on ebay and aftermarket pressure plate and u'll be good.

it can be just a heavy duty act clutch just search for it.

do u get it or do i have to reword it i know what io mean i don't know if u will understand what i mean..
