The 2.5 KL will not bolt up- not even close, and I wouldn't even dream to think of the amount of fabrication and wiring it would take to put that in one of these trucks- in the end it would be useless in my opinion. You would be far better of using the v6 from an mpv or a 929- at least that is RWD and would fit correctly.

As far as this 626 motor swap goes- I think it would be alot easier to swap the b2200 camshaft and front housing onto that engine and get the distributor in the front like it should be rather than moving the engine around!

I second that . . .plus you get to keep your heater.

Bigamigo,I would like to know though, what you are going to do to get the 45 psi fuel pressure you are going to need for the injectors.

And what you are going to do as far as the ECU and harness.

i put a fi pump assembly in the tank and im running the cars harness for the motor and splicing it into my truks harness , and i also upgraded already to a walbro 255 pump so when i crank up the boost ( these little suckers will hold 30psi all stock hehehehehe ) i dont have to pull the bed and change the pump later

Good luck splicing that- there are probably 30-40 wires to deal with, and the 626 harness travels behind the whole dashboard.

30psi stock- I hope you are joking. you'll be lucky to hit 18 before the turbo grenades.

Yep 18 is about right maybe 20 if your lucky but remember he dont care he is still gonna do it.
