Wiring loom
 

Would my wiring loom need to be changed or modified as I'm getting a stiv8 with stiv4 heads fitted once I've got the rest of the parts .

Good choice engine 1st I swear down the sti7/8 engine is awesome , your loom won't need changing only thing I could see is crank sensor poss unsure on heads as the wiring allways changes for no real reason , I did a 94 wrx engine swap with another 94 and the the cam and crank were different but most parts swap over,

If the manifold changes yes otherwise it'll be ok

Cheers C.J. staying with v4 inlet manifold .

Thanks couldn't say no to the stiv8 engine for what the buyer wanted for it and with low mileage .
