Whats different 7mge/ 7mgte

[xander024]

for starters im not retarded i kno tha MGE is NA and the MGTE is turbo...
but where im confused is the specs and what makes the compression different...
i know u can turbo-charge a MGE fairly easy in theory but lots of tuning is involved, but these are the specs that confused me

7MGE Specifications:

Displacement: 2954 cc (180.2 cu in)
Bore: 83.00 mm (3.27 in)
Stroke: 91.00 mm (3.58 in)
Compression Ratio: 9.1:1
Weight: 199 kg (440 lb)

7MGTE Specifications:

Displacement: 2,954 cc (180.3 cu in)
Bore: 83.0 mm (3.27 in)
Stroke: 91.0 mm (3.58 in)
Compression Ratio: 8.4:1
Weight: 210 kg (463 lb)

pretty much i was thinkin' of doin an engine swap but it seems i should turbo charge my MGE instead of buying a new engine... help plz!

The GE some very different timing and fuel maps (you can't just reflash the stock ECU you'll need either a couple piggy backs to tune out the differences, a standalone EMS or to swap in GTE electronics to safely compensate). The GTE uses a higher flowing oil pump, has oil squirters to help cool the pistons, has larger injectors and is accompanied by a higher flow fuel pump... it also uses lower compression pistons (they have a deeper dish which reduces static compression).

In my opinion, having done this before, I highly recommend you do the swap... you'll save a lot of money and start out with a setup that's going to take upgrades with more grace.

Oh, forgot to mention that the ISCV on the GE doesn't have a back flow valve to prevent boost leak and both cars have different intake cams.
