Thanks, I appreciate the compliment. This has been the most fun I've had being frustrated because things at times have not gone the way I laid them out in my head but I am very proud of what I've done. I know it's not professional race shop quality or show car pretty but I did it and to me that's all that counts. I would not trade this experience for the world because I will now have even more appreciation for my machine especially when I'm on track.
Here's where I stopped last night

Plan is to finish installing the intake and get the fuel lines and wiring harness all hooked up this weekend. Damn, I am so close!!

Since I don't see it in the pics, make sure that you hook-up the large ground wire that attach to the engine case.

3.2l rebuild, the quest for more power
 
Thank you but I am happy to say that I did not forget to do that. It actually made me a little nervous because when I was tightening the bolt I felt like I was stripping the case bolt and then the torque wrench clicked. Whew!!!

michael lang 06-21-2015 05:25 PM

Can anyone verify for me whether or not I have the fuel lines hooked. I sent the original ones to BoxsterGT and Len convert them to stainless braided for me. The trouble now is so much time has passed since I've received them I do not remember how they went in and all of my pics only show the the fittings and nothing else. Bentley does not show a very accurate photograph either. Please tell me what you think:

This is where I have the left side fuel rail connected

This is where I have the right side file line routed

And this is where I have the right side connected

And this is where I have the fuel line on the back side of the engine

http://images.tapatalk-cdn.com/15/06...7c0418a7df.jpg

I feel like I did it right, but could someone please look at this and let me know what if anything I did wrong? Thanks in advance

Very productive weekend. Engine tin modified and fitted for the heating backdate. This turned out to be quite the task since I was changing the configuration but keeping the a/c compressor. I didn't realize how much stuff was going to have to be installed, removed, reinstalled again, removed again. It felt like a never ending process.

I must have taken that air tube off four or five times. Between routing of the plug wires, the a/c compressor bracket that bolts above the right upper valve cover and the a/c bracket in front of the tubing, it was quite the tight fit and I will probably come apart with it atleast one more time.
And then there was the modifying of the engine tin to fit for the side panels to allow for the air tubing and the back panel to fit in between the head and the near new SSI's.

One more clean up

And finally get to painting. I ran out just as I was finishing up on the second coat.

I still have the back panel to do. The ends were starting to crack just inside where the nuts were so I want to have that welded first so I will take it to the shop tomorrow and get one of my techs to weld it for me. Plus I'm not sure what I'm going to do with the big hole.

I have two 3.2L builds I've worked on that upped power via 3.4L upgrade, one was single plug other was a twin plug. I provided the MAF conversion and tuning services for both of these engines. You can find details on both builds here:

The single plug engine pulled about 249HP at the wheels
The twin plug about 280HP at the crank

Neither was cheap to build but these are significant, reliable gains over a stock 3.2L

Sorry for the lack of updates, workload has been intense and I have been trying so hard to get the engine finished. It seemed like the same routine over and over, I'd have good intentions in the morning while on my way to work. I'd think..."okay, I'll get such and such done when I get home tonight", well the day would get going and then I'd have dealt with so many other people's car problems and trying to help them fix their lives (the daily life of a service advisor is both very stressful and extremely rewarding on so many levels) that I would be so mentally drained by the time I get home the last thing I want to do is to mess with my own engine.
I have managed to actually get this thing completed, along the homestretch there were a lot of challenges in doing the heating backdate that made me have to lose the a/c which I was really hoping to keep but since I never use it, I figure it lets me keep the overall look I was going after, and "lighter = faster" in having no compressor, brackets and condenser.
This was one of the toughest parts, getting the ignition wires routed to fit around the air flow tubes for the backdate. The tubes get in the way of the original wire path and they are not quite long enough to route in the same path so you have to be really creative in how it's done.

I must have fiddled with it and messed with different configurations, taken the ducts outs put them back in a bazillion times. Probably one of the most frustrating things about the whole rebuild.
In the end, this what I ended up with
http://images.tapatalk-cdn.com/15/07...6273303890.jpg
http://images.tapatalk-cdn.com/15/07...788cbf8073.jpg
The other side was just as challenging, especially with the a/c bracket in the way and the Sceet filling up any of the smallest of gaps.
Thursday evening, myself, my wife and two of my neighbors took the engine off the stand and loaded it into the back of my Takoma so I could take it down to the shop that has my car for it to be gone through to double check my work and to install it into my car. The Porsche gods were smiling on me from ear to ear because Washington D.C. traffic yesterday morning during rush hour even with all the construction on I95 was next to non existent the entire trip all the way to Richmond and back home. With a little luck, I will be burning gas in the next month or so.

Great work Mike. I have enjoyed following your quest for more power. Could do without the "thread hijackers" but I guess everyone has an opinion and feels they must post! Enjoy!

michael lang 07-18-2015 06:27 PM

Thank you and you're welcome. I have to admit this has been by far the biggest challenge I've taken on with my car in the 10 years I've owned it. I tried to post about real situations that regular guys come up against in doing this while at the same time trying to make their money go as far as it possibly can without giving up on quality of parts or when having to sublet work to someone like Dema Elgin of Elgin Cams or Bob Hirsch of Anchor Atlantic for the machine work on the heads. I may be as finished as I can be and when I get the report on the engine after being checked by the shop I left it with I'll report as to how I actually did. Until then, thank you yet once again to everyone that contributed to my rebuild and to those of you who advised me along the way as I struggled with certain things that I now understand much better having now gone through it. I genuinely appreciate all of you and your guidance.

My single plug '87 3.4 with MAF project referred to by Sal actually pulled 248.5 RWHP, translating to 293 at the crank (dyno run is on post #63 on my thread and below). Obviously different dyno's so cannot make a direct comparison.

I got the report back from the shop that has my engine. They have gone through it to double check my work, installed my engine back into my car and the damn thing actually works. Who would've guessed!! Here's a portion of the report Robert sent me:
"Left bank wasn't timed correctly but the right side was close. Valve lash on all cylinders was loose but everything, cam gears, rocker shafts, timing chain ramps were all torqued and properly installed. Passed the initial 20 min break-in-run-in, the engine runs well and there are no leaks"
I realize that is only the short version of what he had to do to get the engine running as I'm sure there are quite a few things he had to do on my engine before he had it running that he is not telling me but damn, I am still having a hard time believing that I actually took that thing apart and got it back together and that it really does work. I am so anxious to hear the exhaust and see what the engine sounds like when the cams come on to power. I am so close to having my car back in my garage, I can hardly wait.

Very nice. I have enjoyed this thread a lot.

michael lang 08-19-2015 09:12 AM

Cairo, I'm glad you have enjoyed my rebuild up to this point. Hopefully it has been helpful to someone else who has been planning something like what I did and will be enough to give them the confidence to take that first step and keep going towards the engine in their mind with their own rebuild. The thing the I appreciated most was that everyone knew I was a first timer and they were nothing but helpful during my whole experience.

gtc 08-20-2015 08:45 AM

Looks great. I just got mine back together and running in May, with oddly enough, almost the exact same upgrades as you.
I had to ditch the 2-1 M&K though... it was too raspy and was damaging my hearing. Maybe it's not so bad from inside a coupe, though.

Did you fire it up yet?

I personally have not but as I stated above in the report from the shop I gave my engine to for them to recheck what I did has.

"Passed the initial 20 min break-in-run-in, the engine runs well and there are no leaks"

First congrats on taking this project on and how much you've achieve.
I have one question, are you expecting 345 hp just by utilizing a 964 cam and SSI ?
Thanks in advance for your reply.
