No, changing the output and ring gear in the trans requires the matching t-case and rear diff.

I have plenty of 1/2 awd gears let me know what you need.

Back when I used to drive to the Shootout, it was 850 miles each way and took me about 3 tanks each way, I could get about 280-300 miles per tank. So ~25ish mpg doing 75-80mph for hours on end. Not bad for a car that was making 450whp at the time.

Maintenance and tuning first, there's a lot left on the table in the stock tune. Make sure to get a good wideband, not glowshift. I've seen their boost gauges be 5 psi off, so clearly quality is not superb.Also keep the boost solenoid as it can be used for electronic boost control through Ecmlink.

If you need bearings it would be almost certainly due to an oil pump failure, at which case the whole block needs to be cleaned and gone through. Was there glitter in the oil pan or something that gave you that idea? If there is no oil pump failure then it's a 99% chance the bearings are...

If I'm not mistaken the T25 needs to be balanced on a VSR balancer as a complete unit, make sure the shop has one, usually makes them not worth repairing.

Shameless plug

Collecting more and more parts for 2024's upgrades.

Buy once, cry once.

Correct and correct but I was referring that they use the oem DSM plug, no adaptor required.

FIC 1200cc high-z are direct plug in with no adaptors, these are my go to for a street car these days.

I made 800 on stock valves, just upgraded springs/cams.

I've reused them many times.If you've got it all apart, clean up the valves and lap them while you're at it.

Share a log with us to look over, 109mph is def not ideal for a red, even on pump gas. In my experience, you'll make more usable power with lower timing and higher boost.
