Hey well while you guys a talking about intercoolers check out my set up! I did noticed a difference with my intercooler on, my car burns more efficiently the diesel since there is colder air supplied. I will upgrade the Turbo. i do like the stock Garrett Turbo BUT! i think lance has a point with the jeep liberty? turbo? his vnt seems to spool a whole lot quicker then my Stock T3 Garrett even tho i am boosting 15 psi. "lighter" compressor wheels must result a quicker turbo spool/boost. Now i have different nozzles in my injectors instead of the stock DNOSD240's Bosch i am going to use larger Bosch DNOSD248's Nozzles since I WILL BE cracking up my fuel pump to deliver more fuel, i check out my fuel pump this past month i think i sould be able to squeeze out 20HP out of it.... and lot's more torque my 3" SS exhaust will be made first to make sure the Exhaust flow is nice without any restrictions.
Lance wellll humm forced i am looking for a turbo to use with my set up you said a Jeep liberty 2.8L CRD Turbo would be good for my W126 617.95X???? Since i own a high performance parts store i have access directly to Garrett, you were talking a GT2256? right that is a small turbo!!, is the liberty turbo bigger smaller or same? i am welcoming good informed technical support on this because my car is ready for paint, so after that i want to upgrade the Turbo. I HAVE ACCESS TO MANY TURBO's i wanna hear your output for a 617.... i sell high performance parts 6/7days but when it comes to my car it's different.... i need to know what you be the BEST.
