we have an opportunity to get a 1988 626 turbo car... complete except for an exhaust manifold.. turbo still there. what would it take to do this swap in the truck? can i use a factory motor with the add ons ( intake manifold, exhaust manifold, turbo, etc...)

Well from what I can tell the 626 2.2 interchange years are 88 to 92, so you should be golden, how many miles on the donor car?

It's a bit involved. #1 You'll have to get an adapter made to flip the intake to face the front of the engine. #2 It looks like you'll have to flip the turbo as well, so that's another custom job.

Here's a swap from beginning to end:

Good call, if it has a ton of miles you would need to rebuild th turbo anyway. There are generic turbo kits out there that would take the same amount of fab skills for around 500.00

^^^ what he said above

- you have to flip the turbo
- flip upper intake plenum (which leads to modifying throttle cable as well)
- you have to swap over the F2 oil pan and pickup as the F2T will interfere with your steering (you are putting a motor that was originall a transverse FWD application to a longitudina RWD application)
- you will need to swap alternators (or just the pulley) or the crank pulley. The pulleys are different between the F2T and the F2, so you need the pulleys on both to match up or your belt will not last if it works at all
- the distributor on the F2T is at the back of the engine and it will hit your firewall so you either have to run megasquirt with spark control to eliminate the distributor altogether, OR you will have to cut out a place in the firewall for clearance, or massage it back about 1"
- you will need to run the B2200 transmission, using a B2200 clutch and flywheel. The stock one WILL NOT stand up to the new motor, so you have a couple options. Centerforce makes a 6puck clutch for the B2200, this will work but is pricey. Your next option is to use a clutch from 626 with a stage 2 clutch. This is easier option solely because there are more people who make performance clutches for the 626 than there are who make them for the B2200. The stock V6 clutch will not hold the torque of the F2t however so you still require a stage 2 clutch. The F2T clutch won't fit inside your bellhousing which is why the V6 or the B2200 ones ar your only options.

As for just swapping parts over to turbo the existing F2 motor, it can be done, and has been done, but all you would really be left with in the end is the block and internals. The F2 head is an 8v design, while the F2/F2T from the cars are a 12v. That aside, they are fairly similar, but in the end a complete F2T swap would be easier as you aren't going to be teaching a motor to compensate fuel for boost that was designed for that. Unless you are going full standalone fuel management like MS, I'd do a complete F2T swap with the ECU and everything. Good luck! It looks to be a fun swap. Nearly twice the HP and MUCH more torque over stock just from this swap.

This is all I can think of at the moment, but I'm sure there is more. I'm BY NO MEANS a pro as I haven't completed this swap yet, but I'm pretty far along so I've run into most of the roadblocks already and can possibly shed some light for you.
