2001 3.6 engine build

[sgt brad]

Pro river, did you do all of the upgrades to chain tensioners,etc? Would you mind listing all of the build specs. 14k. Seems like a good price for someone lookig to upgrade and address all of the failure modes

Sgt, every part of the engine is cleaned & inspected for wear from the case to the bearings & bolts. Anything that can be upgraded is replaced with the best part available. New cam chains, IMS chain tensioner with the external preload spring, LN billet oil pump driveshaft, LN triplerow ceramic IMS bearing upgrade, New IMS chain tensioner paddle, New Cam tensioner wear pads, ARP rod bolts. Lifters & chain tensioners cleaned & tested in new oil heated to 275degrees.All recipricating parts dynamicaly balanced to half gram tolerance. Engine fully prelubed for initial startup including filling oil filter housing & pump & camshafts. Let me know if there are other build specs you are looking for.

prodriver,

it seems like a pretty comprehensive build-up. one of the things that i like about jake's builds is that they address all of the "modes of failure." also having 300+hp ain't bad either.

while i don't need a motor right now, it's always good to have resources. buying a motormeister just doesn't cut it. i may give you a call if/when the time comes.

i think i read somewhere else that you've done 2 of the m96 raby builds. did you ever get the other motor on the dyno to see what kind of power it makes? while i'm leary of instant-g's work, it's hard to argue with his logic that the boxster motor makes significantly less hp/lt than the 996. something is choking it down. i am hoping to unlock the missing hp whenever the rebuild time comes. i am curious if your experience shows that the 3.6 makes 300+ as jake advertises.

Thanks Brad, I am in the middle of my 3rd M96 rebuild now. I haven't done any dyno testing but the power difference is obvious while driving. I'm not familiar with instant-g's work but since the Boxster S got Vario-Cam + in 2003 most of the power increases have ben made with exhaust, intake & DME tweeks. With the exception of displacement size Boxster S & 996 engines are nearly identical, it's the external components that allow the 996's higher output.

just got back in town from a business trip. thanks for the reply. what ancillary components do you think benefit the box the most. it appears to have at least a decent tubular header from the factory. the piping seems awfully small to me, but is the intake really that restrictive? did porsche honestly hamstring the box with that minimal of an intake system? i'm just new to all of this and seeing the 996 3.4 numbers vs. the box s 3.2 numbers makes thing seem screwy. i'm sure this has been beat to death on this forum, but i haven't seen anything on it when i search. that raby is only getting 300hp after the 3.6 build seems low to me (unless those are chassis dyno numbers).

The Boxster components are more restrictive than the 996 & 997 parts as the same year engines are basically identical except for the bore size & If the only variable is bore size 2 different engines should have simular peak horsepower just at different rpm. If you look at Flat6 web page for stage1 3.6 engines it shows 25hp more for the same engine installed in a 996. (chassis dyno numbers)

As some experienced people have mentioned, you have to consider cam timing on one versus the other. Currently, I don't understand how this could be significantly differentiated on the earlier vario cam cars as intake cam phasing in one position or another and no variable valve lift either

Perhaps the vario ram actuator moves diffferently or more on the 996 3.4
