7mgte build opinions

supraluver4life · 05-12-2010, 10:42 PM

so the stock 7mgte internals can handle 400-450 horses reliably? just wanting to know cuz if im gonna rebuild the entire thing might as well do what needs to be done to start with.

The problem isn't with the wheel coming apart, the problem lies in the exponential increase in torsional stress on the spindle. All of the failures I've seen pictures of started with the shaft snapping.

Yes, a HEALTHY 7M-GTE long block can withstand 400-450 (other things will need to be beefed up, of course). But, if you're going to go to all the trouble build for more... it'll last a lot longer.

Sorry man^, I'm pretty sure balance has a little to do with it to though, because if its off balance like a wheel its going to be a little wobbly and will end up doing all sorts of crazy shit. Not saying that your wrong I'm just adding balance to the equation.

sure balance counts, but a freshly rebuilt and upgraded turbo had damned well better have been balanced... if not that's the shops fault, not an inherent weakness.
