2004 Boxster S SE 550 spyder to 3.6

What intake set up will you be using?

Can you tell us if the stock 550 SE intake tract has a helmholtz chamber of any kind?

Pictures would be good but I realize that you must have your hands full

Also very curious to see what the stock air box looks like and how it fits in the engine bay. How is the 987 air box "muffler" chamber accommodated in there???

It may be that this muffler is the helmholtz chamber that we are all shaving off

Oops just realize that you don't have the 550 body

I'm calling it completed but I do need to build a box around the air filter to keep hot exhaust air from the exhaust and compartment from being pull in the engine. the front bumper was installed today



The air filter is OK but not optimal



The exhaust is loud compared to the 2.7 with the same setup. I was able to log about 20 miles this evening with no issues. low end is not a lot better than my original motor. At about 3500 if you pedal the gas it pulls you hard into the seat.

Wow, nice work, I really wanna have LN do a displacement upgrade for my motor someday

Where did you find instructions on how to reassemble the M96?

First there is a U-Tube video set that someone with a cracked cylinder made. The problem with that was no real specs or clearances or torqueing specs. I purchased a Porsche manual for the 2005 - 2008 Boxster it was the only manual out there that covered the 3 chain engine. This had all the clearances. It gave all the torque specs for every bolt in the engine. The timing procedures and it shows what tools you can't do without. It was very good for removing and installing the motor and transmission. My suggestion for anyone going to attempt this is view the video. Then buy a comprehensive manual. I've had many years of experience building motors, a good manual is a must.

Thanks for the info

Last time I checked I couldn't find a manual for the 987. I thought Porsche only had the electronic version they charge a fortune for?
