What I have said in past postings if you are a bean counter this engine doesn't make financial sense in regards that the engine cost much more than the car is worth. But that didn't concern me when I started conversations with Jake about this build. I wanted a real sleeper of a Boxster and that's exactly what I have. I can't wait to get this on Road Atlanta and stretch her legs but I have a lot more miles to get on her before that happens.

Many months have passed now since reading about your build. Congrats! Happy to see it finally come to fruition with more disclosure about out of pocket costs.
I'm the guy with the 03 3.2S in Denver who tracked the car one time (admittedly HOT day) and despite deep sump, no over revs, previous leak down and updated IMS lost a main bearing and toasted motor...(30 years with my 73 911 and not one track failure--guessing 6K miles at high RPM's over the course of that time.) I digress...
In my quest to replace the 3.2, I stumbled across an 03 3.6 with 60k and updated IMS. Leak down good, everything there. I read everything I could...Pelican 101 cover to cover and hit all the forums as well for months. found a shop here in Denver who performed the swap with the agreement being that I could help. After 3 long months, pulling old motor , swapping old to the new, cleaning everything, replacing tensioners, checking chain tolerances, replaced coil packs, gaskets, seals, etc. we were ready to put the motor back in.
Initially, able to fire the car as soon as everything was hooked up but had some immediate tuning issues with Softronic due to bad MAF (replaced twice! ) and the altitude here in Colorado. One mistake, (well actually several mistakes) but thus far, a BIG mistake was that they decided to accelerate the schedule and put the motor back in and when we went to hook things up we realized the error they didn't put the air box in first. I was not there the afternoon that they decided to put it all back in.
By then it would have been too much effort to drop the motor just put the air box in. Time is money...As anyone has done this before and knows, we were already way over budget. So I've been running a simple cone system with a mcguivered hand-built airbox which basically seals the cone to the outside duct coming in.
This is not optimal by any stretch especially as I live on a very dusty dirty road . I think my MAF issues are related to dirt getting in and causing the system to misread. I'd always intended to utilize the stock box because everything I've read says it it's still the best and at my age, I'm not one that needs a lot of noise or things like that.
I retained the stock 3.2 exhaust system with the Pedro Muffler modification due to emission laws where I live. Headers straight pipes and customized Muffler of some sort are slated.
I am using the factory 996 throttle body and was very careful matching the internal diameters and radii to the size of throttle body. All of my bends are very smooth and there are no major disturbances internally. I am using turbo grade clamps and used a 3-inch (or there abouts) aluminum tube to run the distance before it bends again at the side of the car to transition towards the air box. I measured where the factory MAF location is and then used the MAF from the OE housing from the factory to emulate the distance of air flow and pattern of airflow as consistently as possible. I also recreated a mesh out of stainless with the same approximate size grid pattern to recreate the necessary turbulence/air flow pattern for the MAF to read properly.
I am also running an underdrive pulley a 160-degree thermostat with the softronic 3.6 performance tune. With elevation factored, we estimated that we should be seeing about a 10% gross horsepower loss over the factory 300 HP in addition to maybe 5% parasitic drivetrain losses. All that said I was still hoping that I would see a significant performance gain over the 3.2. Having put about 3,000 miles on the conversion I've only had one time where I thought this car performed where it absolutely should. Nonetheless I was very excited about that and know that just a matter of time to Chase what I perceive to be a tune issue. I still think that my MAF is sending the wrong information to the ECU and performance parameters are hindered.
The only time this car PERFORMED to the degree that I thought it would from the beginning was after I had meticulously recleaned the MAF, cleaned the entire intake track to the throttle body (which was quite dirty at that point). I then used carburetor cleaner extensively inside the intake tracks as well.
Any thoughts on anything stated above would be welcome. I realize this is a somewhat complicated deal even though it's described as a plug-and-play with same vintage engine and m96 architecture, ECU, excetera excetera.
Again very glad to hear that Jake has done such an outstanding job with your build. I'd be ecstatic if I had a proportionate level of performance relative to what I've spent to enhance performance over the stock engine at this point.
