Jeep Cherokee XJ 2.5 TD VM Garrett GT2052 Turbo Build
After the failed test drive with the GT2871R clone I decided to choose a more suitable turbo charger for my 425OHV Engine, a genuine Garrett GT2052. The GT2871R is a duel ball bearing turbo with a very fast spool up but due to the size of the compressor wheels it takes a lot of exhaust gas to get that them moving. The best I could get out of it was it coming in at 3000rpm which is extremely late on the rpm range for this engine and basically useless low end where the power is needed.
The GT2052 is comparable in size to the old VA180069 stock turbo originally in the MK1 425OHV although it can push more boost and spool up very fast.
The modification seems to have paid off although finer tuning could be done with regards to fuel and boost to get a safe but more powerful setup. This is something I have little knowledge in doing and thus begins another chapter.
