Take 2 > S4 TII into S5 TII Shell

Description: Alright here's the deal.

I have swapped an s4 tII motor into my s5 tII shell using all of the S5 TII parts "front cover, uim, lim, injectors, tb" successfully.

Now the issue I am having now is.

My S5 TII is now just a shell again, this time with no s5 parts left over. No intake mani's, maf, nothing except the s5 wiring is left.

I bought a ratty *** S4 TII car with a great running motor. Now I don't care about running premix so I figure I can leave the s4 front cover on.

Questions:


1: Leaving s4 front cover on and running premix.. possibly just plugging a s5 omp into the harness and letting it hang

2: Would the only way to accomplish this mission be too buy a s5 upper and lower, injectors, maf and tb?

I would just swap the ecu/engine harness from the s4. The engine won't run 100% right on the s5 ecu as the compression is different between the two motors.

Yes its a fully running/functioning S4. I don't see how it would be plug and play though
