Got the chance of getting a Vf28 turbo from a P1 will this work on my wrx (94 model) or do you need alot of mods dun for it to run properly and safe!. I do have a sti fule pump not fitted yet tho, my ecu has been chipped dont know if that helps or not, any comments welcome.

 

It will most probably need a remap.
Find out what the ecu chip is mapped for.
The td05 in your car is good for about 320ish bhp
