Well...youll need a narrow block 4g63t engine from a 90-91 Eclipse/Talon/Laser( also known as a 6-bolt engine widely known to be a better engine than the 7-bolt which is from 92-up), the transmission (km-132) from a 2.0 mighty max, and a mighty max. From there you will need a mixture of parts including the ECU, wire harness, fuel pump, throttle body, MAF, water pump from the G63b(2.0 mighty max engine) sensors and such. You have to flip the turbo around 180 degrees so that the compresor side is toward th front of the engin bay. Now you have several options for mounting the engine. You can A beat the hell out of your fire was to clearance the CAS and water outlets.
Or B you go the "better" rout and make custon 3 inch motor mount extensions, tranny mout extension, extend the drive shaft, and swap the tail shaft from starguest transmission.
Once you decide what you want and get everything mounted and in the truck, you have the intake manifold to deal with. You also have options her. You can make a cap for the stock throttle body and cut a hole and weld a plate on the other side for the throttle body.(this is done it the picture with the engie moved forward_)
Or you can make your one.
Or buy one.
Now once you have all that in and fitted nicely the easy part is done!!!!!!!
