993 Performance Upgrades

[the-goose]

When I bought my 1997 993 C2 Tiptronic a year ago the power was good, but recently the car feels less than adequate in the power department. It feels really lazy, as if its going uphill all the time, especially at slower speeds. Could there be something wrong with the engine i.e. spark plugs, inectors, MAF sensor etc.? Also, since I probably have to do some work on the engine I thought I would take the opportunity to do some additional power upgrades.

What bolt on parts can I install onto the stock 3.6L motor to boost the HP to more "current" standards. I was thinking about the following for starters:

New spark plugs

New injection wires - Expensive

New MAF sensor - Quite expensive

Flushed out injectors

New fuel filter

New distributor cap

Perhaps even a chipped DME... - Very expensive

Will these easy fixes actually boost power or am I barking up the wrong tree? What do you suggest?

Thanks!!

expensive and time consuming list.

maybe try some elimination first, check hoses and vacuum lines, make sure current plug wires are on snug...

then start by changing the fuel filter which is easy.

try cleaning the maf before buying new, I've read some people have been able to do clean it succesfully.

one big thing you can do tat doesnt cost much is to have the fuel injectors tested and if necessary calibrated on a fuel rig. Its amazing how they go off spec over time... These are the culprits for a lot of lost bhp....
