Hmm.. Looks like it got resized, I guess you can`t see the text. I can send it to you in the original size, that`s readable, lmk if you need it.

Got it.

I think I'm gonna try giving the crank angle sensor some voltage from the tach wire. I'm hoping that might trick the computer to think that the engine is running. I think that might cure what ails me.

If not I guess I've gotta wire stuff up.

Last image dump.. The body isn't gonna change much at this point so picture viewers can sign off now.

I have the "tuning top" on the car right now. It makes it soooooo much easier to make carb/timing or other tuning changes when the hatch isn't on the car.

OK sitrep I have cooling fans when the engine gets up to temp. The problem is the fans cool off the radiators... and the radiators are 2 meters from the sensor. Maybe some day in the future I'll wire up an electric water pump to turn on when the fans do. That way if I shut the car down the fans won't run FOREVER. ATM I wired them to turn off when key is in the off position.

There is NO power to the relay 2 box. I'm gonna try to hot wire the relay 2 box tomorrow. That might give me A/C voltage.

As for the tac... I'm still up in the air. I think I might honestly just get a Porsche CAS and glue a picup sensor to my flywheel. Kind of a jerry rig situation, but who cares.




Anyways, she is lookin suuuuuwweeeeeet. [You're supposed to read that with a good southern inflection]

















PS: yeah, I know that right fender is fubar... the door is questionable.

The propane diffuser fits.

Too much compression... too much boost... Too much timing... not enough ring gap... not enough fuel...

Muy muy mallo...




Its all good though. I sorta clocked myself working on the boxsterado this time. It took all of 4 hours to get from running engine to pistons out. Granted I am a "professional" mechanic, but even by my standards thats a pretty easy engine to work on.





The washer machine looks good though





Well lesson learned; I got some deep dish pistons on order and I said to hell with it and ordered some Eagle H beam rods. Cause why not.

So, after some maths, I found out that my CR with the old pistons was about 11.1:1. TIDAK BAGUS!!! I mean I could run E85, but no, just no. I could have just run strait propane, but I like the versatility of gasoline. I mean when you are camping and you need to start a fire you just unplug the fuel line and BOOM instant fire. LOL


With the new pistons and eagle rods my CR should be about 9.7:1. Which IMPO is still kinda high for boost, but definitely doable with 93 octane. I really wanted to be able to run like 87, but oh well.


Just gotta hone out the block and slap these buggers back in there.

So after 1000 miles I think this machine is about in its final form.


I ditched the hot air intake and made this cold ram air intake. I blocked off the original hole and made my own in where the top would normally sit. In theory this should shoot cold air from the side intake into the conic filter that feeds the carb. In reality it makes cool intake noises from the side of the car.




My fear of a VERY unbalanced plenum is put at ease a little bit by making this "gutter" to feed cylinder #6. Its just a piece of steel in a gutter shape that is bolted to the intake; then the piece is welded to the bolt. All the parts are larger than the intake runners so I'm not afraid it will get sucked into the engine. But it should help charge #6 as much as 1-5.








And lastly I finalized my A/C situation. I just jumped strait off the A/C cycling switch to a toggle switch to power my A/C compressor. I have a toggle switch to turn my A/C on; not too happy about that. BUT it works and cycles under pressure changes, and the HVAC works just as stock otherwise.



And after driving for a while now I can say its a hoot. Yall already know how spectacular the handling is, and the creature comforts are just as amazing as I remembered them to be. The car is not as powerful as I'd wanted, but much more than a stock boxster. Butt dyno measures 300hp at the wheels. More than a boxster S; which is plenty. If I really want more I can always put a shot of giggle gas on there; lord knows the IRON block will take it with stride.
