And all I see is talk of conversions. Are NA to TT engine swaps not talked about just because they're so easily done? or is it that they are too difficult or too much money to undertake?
Basically my questions are:
1. What are the main concerns dropping a TT engine into a NA frame?
2. Mounts fit just right? or need some weird metal work done? I know the frames are different, but dunno if the mount holes/bolts line up anyway.
3. Do you just swap the entire wiring harness all the way from the TT ECU to the entire engine bay?
4. Should the master cylinder and/or brake booster be upgraded? Calipers, rotors too?
5. Can you just buy a TT shortblock and put everything from the NA engine on top of it? Yes, I know I'm showing what I don't know. lol
6. What else?
I'm asking all this for a friend actually. |
DOHC blocks and heads are physically the same, so yes a tt engine will bolt right into the NA frame. All engine mounts are the same, the TT tranny mount is different as is the transmission(however FWD trannies will bolt up to TT engine blocks just fine and vice versa (as the blocks are the same)).
It would be a smart idea to swap harnesses just to make it easier as there are small differences, however you can make an NA harness work just fine on a TT engine, assuming OBD's are the same.
Brake cylinders, clutch cylinders, brake booster's are all fine to use when swapping in a tt engine. If you want more braking power then sure upgrade the brakes.
And yes you can just take a TT block and swap all the NA stuff onto it, assuming the are the same generation/OBD stuff.
TT engine swaps arent as common because people doing TT conversions are cheap and want to do it as cheap as possible. Spending an extra $500-$1500 for an engine when not absolutely necessary ussually doesnt fit into people's budgets.
