Highest Mileage Built motors and turbos??
I never see this information much often on here. I wanted to make an easy to access thread for information on how many miles you all have put on your built motors and or turbos.
Example: br 2.0 / je pistons etc 30800 miles and going
TurbO: pt 6265: 8000 miles no issues etc.
I figure this might help out folks like me who wonder about this. Thanks and I hope to see somee hiiiiigh numbers

This is a good thread however, the mileage will be all over the place. Usually the higher HP builds won't last as long as a built motor with a stock turbo. I would be very happy if my motor makes it to 50k. The main thing with a high HP built motor is monitoring your bearings. I expect ill change my bearings every 15-20k.
English Racing 2.4LR 10.5:1 MIVEC motor. Wiseco HD 87mm 1.13ch w/ 156mm GSC Ibeams slinging around 100mm crank at 8650 rpms.
8K miles so far and no problems. Running 6.5 quarts of 20w50 Brad Penn. I change the oil between 2-3k miles depending on how much wear the oil has had. I won't go over 3k miles on oil since I run E85 99% of the time.

is it due to your compression being higher or the fp black? the acl race bearings need to be replaced that often? If so what does that entail for you? pulling the head, pistons etc and replacing the race bearings? damn man that seems like some maintenance i didnt think of

That, and 700+ hp. We have tiny little bearings in our cars and more power ends up requiring more frequent replacement since they take a lot of the beatings.
You could go to an alum rod motor to absorb the bearing abuse, but then there's other issues with that.
My home built 2.4l in my talon has about 15k miles 50% of the time on E85 and 25psi on an EvoIII. Still running strong.

The other factors that you have to address when making a motor last is tq, timing (high timing means high cylinder pressure), and load in low rpms. It is important that people understand that there is no such thing as an indestructible motor...
Not a lot of labor, it is pretty easy to press in new rod bearings. Those tend to be the ones that go first and take a built motor out.

this would explain why aaron said he used h beams since they hold up but aren't that heavy like the turbo tuff rod. I understand now.
So if a motor had a very graduallll curve and a slow climing flat tq curve with h beam rod and un aggressive timing, your motor would have a better chance of lasting correct?

id max at 450 tq for me and a gradual band. so after 8k miles you're doing fine with no issues i see. Are you using a cometic head gasket for the 2.4 or are you using ams? what are your thoughts on the l19 headstuds? do you find that the standard arp headstuds stretch under that kind of power?
