Need to Drop a Boxster motor a few inches... Help!


Recommended Posts


How do I temporarily drop my engine a few inches. I’ve got a TPC super charger that’s got one pipe from the “below board” sc up to the top deck. TPC claims 100% bolt in. Everyone I met spent hours trying to fit the pipe in ( I did and gave up).

A knowledgeable guy said “just drop the engine a few, no prob”. Makes sense to me, but how?

I’ve yanked and dropped lots of engines, can’t imagine this one is any big trick but the factory manual is so arcane. I stopped reading after the 4th page of describing some crazed, complicated contraption your supposed build to remove the engine.

Again, I only need to lower it a few inches. Any body no a DIY thread or wannna make one make on with som practical directions?

Thanks a lot, P.K

I'm no certified mechanic but when I changed my engine mount, the engine dropped or inclined downward. Unbolt the main engine mount and hold the engine with a hydraulic jack. Make sure it well supported, you don't want it falling on you and not enjoy your S/C !!!!


Jack stands and a floor jack is all I ever needed. The engine removal section of the manual would have you build this contraption. Than, remove the muffler, power steering, bumper, cables, hose, et al.

After 23 pages of that, The last page gets to the heart of things, the main bolts. Unscrew 4 “front engine carrier” nuts and, (appears to be) the same with 4 “transmission support” nuts.

Gona guess I can skip the first 23 pages, (removal contraption and all the dissambly) and do the 8 or so nuts in the previous paragraph: Loosen the trans bolts, remove the engine bolts, & lower the floor jack a bit & Undo anything that starts to stretch.

With your knowledge, does this sound like a simple game plan that will work?

The manual also states (in relation to the transmission bolts) that removing the “multi tooth nut” destroys the mount. What’s up with that!?

Do you need to lower it temporarily or permanently? Sergio's response is absolutely correct if you're just trying to lower it a bit to get something in or out. Otherwise it is a bit more complicated.

Ya, I just need to lower it enough to wiggle a tube in. Supposed to go in without droping the engine so I assume I won't have to go down to far. I've heard it's the trick.

As stated, loosen/ remove the front engine mount to chassis bolts until you get the clearance you need. If you only drop it ~2 inches you won't have any issues with strainng the fuel lines, wiring harness etc.


Thanks todd,

No messing around with the exhaust and the like? I hope 2” does it.

Forget if you've put one of these things in yourself. Heard that you want replace the plugs (at min on the sc side before you but the SC...no brainer). Also herd though, that you should avoid platinum plugs with the sc. If that's up your alley & true, what is a long lasting plug appropriate for sc application.

Thanx, PK
