Smile Starting from scratch: '93 L with a WRX motor

Ideas have been bouncing around my mind like pinballs. I'm selling my autocross car (VW Scirocco) and putting the funds towards my brothers daily driver (and moster project). We're looking for cheap L. What we would like to do is swap in a WRX motor. We've found an inexpensive 4WD 1.8L 5 speed.

I've skimmed over a few threads that detailed the USDM WRX motor swap into a GC8. What was unclear was the strength of the transmissions and what to do about a drivetrain. Is the '93 L transmisson just as strong as an RS and WRX? I find this very unlikely but a few have said that it is. If it is, then we'll pick up the AWD L and just swap the motors. If it isn't, we'll get a WRX motor and transmission and swap it in. But then we'll need a new rear dif and axles. We can get a FWD L cheaper, so should we bother with this AWD L if we need the majority of the WRX driveline?

The goal is to get a V7 motor thats complete from intercooler to oil pan and drop it into my WRX and use the WRX motor in the L. We'd like to get both projects completed before next spring and have a low 12 second WRX/STi and a mid 12 second L/WRX that both make great daily drivers and autocross cars.

I'm mechanic by trade and I'm looking for advise from others who have done this already. I haven't taken on a project of this proportion before and I think it will be a great learning experience and a very rewarding project when completed.

Cliff notes:
1.) Are the L/RS/WRX transmissions all the same strength?
2.) Is it necessary to start with an AWD 5spd L if you're swapping in the transmission, rear dif, and axles of a WRX?
3.) Any advise for someone doing a WRX swap into an L?
4.) Do you have an L for sale?
5.) Want to buy a VW Scirocco?
6.) Do you want to help?

Thanks guys,
Pete

It's not necessary to start with an AWD 5-speed...but you might be further ahead. The AWD gas tank has clearance for the driveshaft. The AWD rear crossmember has the mounts for the rear diff. If you choose to use the L tranny...you have everything you need. If not...you can probably find someone who could use a tranny and rear diff from an L(more funds for the project.)...the FWD parts would be throw-away. The 5-speed is a better choice because you will have the pedal-box for whatever tranny you go with. The FWD are sometimes cheaper...but you will have to buy a few things and spend a few extra hours swaping parts.

Read stimpy's write-up in the FAQ section...should cover the "advice" part of your question.

the 93 AWD tranny is not the same casting as the later units . much smaller
it is however a 4.11
i would be very concerned about putting v.7 power in to one

however just about any thing made after 1990 will bolt up.. rule of thumb - match the clutch/flywheel to the tranny not the engine

my tranny has 175000 miles on it .. so far so good .. but i am also running an open rear diff

for long term durability consider a wrx tranny and do the cable-hydrolic conversion at the same time as the motor/wireing

Sounds like a fun project Pete.

Unfortunately, I don't want your VW, but I would definitely like to see the finished car, and I can offer any moral support you might need.

My WRX will be getting the v.7 powah!
The L will get the WRX motor, STi intercooler, VF34 and the pinks. So yeah, I guess the L will have power levels close to that of a v.7 STi.

I guess we'll try and pick up that AWD 5spd and find a WRX transmission.

Thanks again,
Pete

It might be a while before we get all our ducks in a row.
