Models This kit will fit: 1990-1993 300E-24 1990-1993 300CE-24 1990-1993 300SL-24 1990-1993 300TE-24 1994-1995 E320 1996-1997 E320 1994-1997 SL320 1994-1997 C280 1995-1997 S320 1996-1997 C36 The kit is capable of up to 600hp with the appropriate engine modifications. On the stock M104 engine it can produce up to 400rwhp with a water/methanol kit. Parts included in the kit: T3/60-1 Garrett Turbocharger, 600hp capable 38mm Wastegate with 4psi spring Hallman Pro RX Mechanical Boost Controller(best MBC on the market) Steel braided vacuum lines Heat sock for turbo(increases spool time, decreases under-hood temperatures) Custom T3 turbo manifold Greddy Type-RS BOV Breather Caps 27x6.5x2.5 Intercooler(good for 400hp) 2.25" Intercooler piping and fittings (fitted for a w210 e320's, other vehicles will need different routing) 30lbs/hr Ford Racing EV6 Fuel Injectors(fits 96-97 320/280 models, I can get the same injectors for 94-95 models) 3" Air Filter with reducer for MAF(CAI option for 96-97 E320 if wanted) Oil feed lines Oil drain lines All other needed hardware. The kit has been driven on for 2100 miles. It made 427rwhp at 16.5psi in my e320 and 352rwhp at 9psi. Here is a video of the kit after I lowered the compression of the motor, it is a baseline run to see what the power was at 9psi with lowered compression: http://www.youtube.com/watch?v=3dCFM0qa67o Installation Notes for those who asked questions: Components that need to be modified: - If your car has EGR(Exhaust Gas Recirculation) it will either need to be removed or you could have a muffler shop weld a bung into the header that would allow you to keep it. My particular car, a 1997 E320, did not have EGR so it was not a problem for me. Estimated cost for this fix, assuming YOU do the measurements, is no more than 25 USD. - If your car has a Secondary Air system you can either remove it(which will throw a CEL every couple of weeks) or carefully cut the mounts off of the stock bank one header and re-tack it to the turbo header. Estimated cost for this fix, also assuming YOU do the measurements, is no more than 20 USD. - The Intake Resonance Flap which somewhat variates the air distribution can be removed without triggering a CEL and replaced with a vacuum plate that allows a great location for BOV vacuum sources and other vacuum dependent devices you may install. It also allows ample space for a water/methanol kit if you are running high boost on the stock engine Since the car is now Forced Inducted the runner length variation isn't needed. - If you don't run the turbo heat sock(which is included) you will have to relocate the coolant pump that runs coolant to the duo valve(controls the heat on the climate control) as show in the pictures. If you run the heat sock you won't have to worry about it. - The Oil Pan or Engine block needs to have a 10 AN bung weld into it for Oil Drain from the turbo. The bung and fitting are included in the auction. It cost me 30 USD to have the bung welded to my oil pan. I took the pan off in my home garage and I can instruct you on how to do the same. - If you want the Front Mount Intercooler to have a more secure mounting location you can hammer up the tabs on the bumper support with a rubber mallet, drill a hole big enough for the supplied bolts, and mount the intercooler using the middle mounting location. Technical Installation Notes: - The oil feed comes from a 12x1.5mm plug located on the driver side of the oil filter housing. It is easily removed with a 6mm allen key and replaced with the supplied 12x1.5mm to -4AN conversion fitting. - The throttle body coupler is extremely tight so that it does not interfere with the electronic throttle of the later M104 engines. Be patient when putting it on because it will take a while. Make sure that the clamp screw on the throttle body coupler is not interfering with the throttle arm or it will change the start up timing of the car which will cause the car to heavily backfire. This is easily avoided it you make sure the clamp screw is to the front, left or right of the throttle body but NEVER to the back. - Make sure the turbo is facing straight up and down for proper oil feed and drain. Maintenance: - Run only synthetic oil and the highest octane gas available to you. Tuning: - The kit does not include a way to tune the car but message me and include your car's information and I will show you what you will need to purchase so you can tune your M104.
