This Tuesday I am having the 178mm crank pulley and PSK installed with a 70mm SC pulley. A PLX wideband O2 sensor/gauge will also be installed with an SL55 fuel pump/filter and Rob's adjustable fuel pressure regulator. The AFR goal is 12.0:1.

So far I have Rob's DCAI which I will insulate for peace of mind. Plugs and wires have been replaced along with fresh oil. It has the radiator/heat exchanger separation kit. The 65mm SC pulley will be replaced with a 70mm pulley for a stacked set-up of 178/70 which should bring the SC Rpm's right around the limit of 15,000rpm. Stock injectors will be used.

The motor has 79k miles on it and the vehicle is an '02 SLK32 AMG.

Suggestions for further mods? By the way I plan on the ported lower "Y" and "tweaked intakes". After those I think that is it.

I have a pair of PYPES high flow cats from my Cobra motor. I had thought of replacing the front cats with them, changing the h-pipe to an x-pipe, deleting the resonator and changing the stock muffler to a Borla Pro XS. The Borla's are loud but they do not drone. The x-pipe would quiet them some. Unfortunatly I don't think this extensive exhaust work would add 15whp as the Mercedes engineers seem to have done a very good job.

Anything else that offers a decent return on the investment for added torque or should I start the cosmetics? On EBAY a company offers stock wheels, chromed, for $747, shipped with a $1200. deposit. My stock Mercedes wheels are fine and should command the full deposit refunded. I have an SLK32.

Before I go the cosmetic route I want to exhaust the added torque mods. Suggestions please? Mark

PS: my tune is a E/C from Jerry. it is possible there is 15whp to be had with a different tuner but who?
The killer chiller would be difficult due to space restrictions of the SLK compared to the Crossfire but still possible, cooling tunes are always responded to very well by the motor. being in southern Florida I thought a cooler T-stat might help for the summer but does anyone know what auto store sells a 160 or 180* STAT?
I am looking for spare hood if anyone knows of one please let me know if reasonably priced, I have an idea for allowing the hot underhood heat out to some extent. Thanks, mark
