I found a local guy who rebuilds T5s. I was referred to him by a few local guys.
New gear 85-93 T5 is $1100 plus core (will be 90-93 gearset, heavy duty steel main support plate and steel front bearing retainer). Stock rebuild with used gears and no support plate is $800 with core.
Both options "include a full rebuild kit which includes: Synchros(new 1-2, 3-4, and 5th), tapered bearings/races, tail shaft bushing, spacers, shift pads, seals, and misc. small parts
He continues on with "I also replace any gears, sliders, shift forks, shafts, springs, keys, or other parts that show beyond usable wear. I always use a steel bearing retainer. I'm very picky about parts that show much wear at all being reused. I also set the main shaft end play, and main cluster end play to exact specs on the tight side."
I was thinking about tearing down my 4 cylinder T5 myself and rebuilding the components for V8. Based on his pricing, I'm apt to just buy one of his after pricing things out to rebuild/convert mine. I I purchased one, I think I'll go with the new gears and added steel main support plate so I can grow into the trans.
