Lol I have personally found the more i Mod and run the car the more reliable it is lol... ive had the car for 4 years and have put about 50,000 miles on it and the only mechanical problem i have had was valve cover leak and bad motor mounts. Ive ran the 65mm pulley, DCAI, big manifolds, catless downpipes, supercooler, killer chiller,ecu tune, teflon y pipe for 3 years and seen much track time and made 361whp and 361wtq on dyno on hot florida summer day.. my car now has the 185mm pulley, 55 fuel pump, 550 injectors, bigger ic pump and besides running rich i have no problems! I also assume the car now has close to 400whp.. it has that setup for 5 months and no mechanical issues.. oh and it has 105,000 miles on the clock! Headers and meth kit would be next options after bigger crank pulley!
Like Chuk said.. be patient and mod it right.. it will last
