98 Forester Engine Swap--which one

2002WRX_5speed · 05-18-2005, 08:21 AM

Anyone know what engine will be the easiest (plug and play) to swap for a 98 Forester (automatic)? I am thinking of a 02-03 WRX (USDM) and add a FMIC. Will the wiring be a nightmare? Which JDM engine? Any suggestion....thanks

Swapping a '98 Forester is just the same as swapping a '98 Impreza. Read the stickies and FAQs and you should get a pretty good idea of what's involved in a USDM WRX swap.

well, if you want to retain 4EAT, you have to get 4EAT wrx ECU and TCU modules, since WRX 4EAT is very different from Forester

if you must have the auto. you will have more problems.
it would be easier to get a 5spd and throw it in there then make the 4eat work.

5/6 speed is not an option right now since this will be my wifes car. She doesn't know how to drive one. So the engine swap is not really the big issue but the transmission will be. I am not sure but does WRX come in automatic???

AVO turbokit instead maybe?

How much power does your wife need?

i think he was trying to be funny afaik they are the same unit
keep the forster tcu

and no a turbo kit is never a good idea they always blow up always

Your going to let your wife drive your swap project as a DD, especially with a “FMIC” which begs for a larger turbo and increased HP? Brave man….

nope, WRX TCU split is somewhat 50:50 all the time will slightly more to the rear, while RS/Forester varies up to 90:10

I don't know if WRX ECU will recognize Forester TCU, but perhaps it's work
