Boostin my GE

[IOWA1234]

I plan on boosting my MK3 7mge. Im want to make sure I have everything I need. Manifold/turbo, Wastegate, Downpipe, Intercooler/Piping, BOV, gte ECU. Also associaded fitting and lines needed for installation. Is there anything I missed let me know please. And Does anyone know how much boost these engines hold on stock internals and where to get an LSD.

Don't bother, just swap in a 7MGTE.

they arent hard to come by .... and they arent expensive - plenty of turbo MK3's running around

and you will have the same results, if not better

Either way is fine as long as you don't cheap out. If the engine you've got is in excellent shape it may end up costing you less in the long run than if you end up having to completely rebuild a GTE with an unknown history.

The things to keep in mind are that the GE's AFM is EXTREMELY restrictive, the ignition map is MUCH more aggressive than the GTE's, and the compression ratio is higher. You can install a MAFT Pro to eliminate the AFM and control ignition timing and boost.

Also, keep in mind that while the GTE's ECU has a less aggressive timing map, the timing should still probably be pulled back a few degrees further at higher RPM due to the engine's higher compression ratio.



Now, back to your list:

I'd recommend installing a new GTE oil pump. You'll need an oil cooler with thermostatic bypass. A boost controller would be advisable. If you're swapping in the GTE ECU you'll need the engine harness for it, the HAC sensor (if it's pre89), most of the engine electronics (incl. ignitor, coil packs, KV AFM). You'll need bigger injectors and it wouldn't hurt to upgrade your fuel pump.
