Rebuilt engine options?

[Robert986]

Not to hijack the original thread but since it´s being discussed..

How hard is it really.. to rebuild a M96 on your own? I have rebuilt one engine and fixed and serviced a lot of others, but never opened up a Porsche engine, certainly not the M96. Sometimes it sound like it really is rocket science and you need to pay a super premium to get it rebuilt.

I have a very vague fantasy about one day rebuilding a M96 myself with the specs and improvements I want..

Can it be done by a "normal" car-guy just taking it slow an paying attention to details?

Essentially it`s similar to any other engine, not rocket science. Of course, it`s more complicated than, say, an in-line four due to the flat arrangement, so you need more special tools for a rebuild and there is a number of steps that are not plausable. What is really annoying though is that there is no repair manual available, except for the used ones for over a $1000. But you can actually collect all the information needed from the web, it`s time consuming though.

I have a pdf shop manual of the boxster to 2004 but really the manual does not cover 2003-04 it stops at 2002.
I also got on the internet the 2005 -2008 shop manual. this covers engine changes on the 2003 -2007 but not the 2008
If messaged I could email them.

I've built 2, 2004 motors the shop manuals mentioned do the repairs/rebuild justice. 2 tool kits are required pin kit, and timing kit, torque wrench to 7nm and angel gauge. parts and tool with LN block mod could be done for $10K. improved for another 2-5K. the one upgrade is carrillo rods, these are a must if you accidently over rev.

I've seen several ford, Chevy, and Audi hack jobs all require body chopping and weld reconstruction. I was not impressed.

Meh, I'll take a hack job over rebuilding an engine every 150 000 miles.

I'm not too impressed with Porsche's engineering of the water cooled H6. I mean Subaru does a great job with power to boot*; what stopped Porsche from following Subaru's lead.


*I will say that there is an issue with head gaskets. LOL

I built an m97 for my friends race car. Few steps which you have to sit and think about and the wrist pin clip took us 2 tries...yes you have to split case again, but overall not too bad at all. I have rebuilt a few engines as well but not an expert
