George@GTM · 11-18-2007, 07:39 PM

This car was built a little over a year and half ago. Over 8,000 miles on our GTM Stage 1 long block, still urning strong, and making good power. Car came in because it was having some smoking issues recently. The owner (Crom) decided to bring it in so we can diagnose the problem. Their were 2 possibilities, either a engine issue or a turbo problem. We did preform a compression and leak down check, everything was perfect, even the spark plugs showed signs of a good burning engine with no traces of oil.

We did send the turbos to get inspected, during the inspection it was determined that one of the seals had gone bad. The turbos could have been sent to APS to see if they would warranty them, but there was no idea on how long that could possibly take. With Crom knowing that we decided to have them rebuilt with a 2871R cartridge. Turn around time to get the turbos rebuilt was only 10 days so this was the fastest way to get the job done.

The turbos were changed, car was checked over, and then re-tuned. Car is running great just as the first day it left the shop, we hope Crom is happy!
