Just read your thread and starting from page one noticed the pic of the factory ported intake ports. I don't believe I have ever seen a port job that left the casting marks intact?
Great job! Awesome work!

My understanding is that they were cast with larger ports as compared to standard 2.0L heads. I agree, they don't appear to be hand ported.

Brit continues with the mantra of "It's never done" or continuous improvement ....pick one. My spirit was strong but my wallet was weak.
The car did OK for with my low rent efforts but Brit is moving to a higher level......but it still requires development. No instant gratification here..just a lot of hard work. I am confident that he will make it work.

Braved the 605 and the 5 Saturday to see the project. Amazing attention to "how stuff works". Gonna end up with an insane power to weight ratio in a chassis that should handle like a slot car. Impressive! I look forward to seeing it run some events.

What's the schedule for the car Britain, i.e., are you planning any early events in 2012?

Excellent planning and execution.

The current goal to have the car ready for testing by mid-Feb. Based on the amount that we got done in the last few days, that goal is feasible. I fly back to Portland tomorrow and I will have some time to post some new pictures. Wait till you see what we got done on the rear suspension...it is amazing.

Just got back from another 4 days in sunny SoCal working on the racecar. 12-15hrs days, but we got a lot done. Check it out.

Lower bars of the rear sub-frame completed. These two bars took 5 attempted to get right. They had to contact 4 points with two compound bends and angled cuts. They intersect the frame rails in the front and the transmission mounts in the back.

(IMG:http://www.914world.com/bbs2/uploads_offsite/a1.sphotos.ak.fbcdn.net-364-1323839824.1.jpg)

Side view of the lower sub-frame in place without the engine and transmission in place. Used an extra 901 nosecone to locate the transmission mounts.

(IMG:http://www.914world.com/bbs2/uploads_offsite/a3.sphotos.ak.fbcdn.net-364-1323839824.2.jpg)

Jigs in place to locate the proper pick-ups points for the upper mounts. The upper mounts are in-board 1/4" to achieve more negative camber compared to a stock lotus.

(IMG:http://www.914world.com/bbs2/uploads_offsite/a4.sphotos.ak.fbcdn.net-364-1323839824.3.jpg)

Rear suspension control arms in place at the upper pick-up point. Additional rear body mount added for the upper mount bar to hit the chassis.

(IMG:http://www.914world.com/bbs2/uploads_offsite/a6.sphotos.ak.fbcdn.net-364-1323839825.4.jpg)

Rear Lotus wheel mounted on the car.

The rear sub-frame will also be a cradle for the engine mounts. This will free up some much needed room in the front of the engine. These utilize the stock Subaru engine mount parts with a few modifications.

(IMG:http://www.914world.com/bbs2/uploads_offsite/a3.sphotos.ak.fbcdn.net-364-1323839951.1.jpg)

Engine in place in the new sub-frame and bolted to the car. There will be an additional cross-bar in place between the frame rails.

(IMG:http://www.914world.com/bbs2/uploads_offsite/a6.sphotos.ak.fbcdn.net-364-1323839952.2.jpg)

The sub-frame will unbolt from the car and the engine, transmission, and rear suspension will come out as one piece.

(IMG:http://www.914world.com/bbs2/uploads_offsite/a1.sphotos.ak.fbcdn.net-364-1323839952.3.jpg)

Side view of the sub-frame. The will be an additional bar across the front of the engine to support the turbo and other items that used to be mounted to the old crossbar.

(IMG:http://www.914world.com/bbs2/uploads_offsite/a7.sphotos.ak.fbcdn.net-364-1323839953.4.jpg)

Completed rear sub-frame in place in the car for final welding. Here you can see the new engine mounts.

I knew the day would come sooner or later, but here we are cutting out the old cage.

(IMG:http://www.914world.com/bbs2/uploads_offsite/a3.sphotos.ak.fbcdn.net-364-1323840127.1.jpg)

The old cage was 1.75" x 0.120" and weighed in at 92lbs. It was a bit heavy as you can tell from my expression here.

(IMG:http://www.914world.com/bbs2/uploads_offsite/a2.sphotos.ak.fbcdn.net-364-1323840127.2.jpg)

Pile of bars from the old cage. 92lbs of steel sitting here. I estimate that the new cage will be approximately 50lbs.

(IMG:http://www.914world.com/bbs2/uploads_offsite/a7.sphotos.ak.fbcdn.net-364-1323840128.3.jpg)

View from the rear without the cage. The new cage will tie in the frame rails as well as the two bars sticking up in the rear which are the upper sub-frame mounts.

(IMG:http://www.914world.com/bbs2/uploads_offsite/hphotos-iad1.fbcdn.net-364-1323840128.4.jpg)

Additional structure related to the old suspension cut out of the front. Material will be added back to the wheel wells and the cage will extend forward to pick-up the front suspension assembly.

(IMG:http://www.914world.com/bbs2/uploads_offsite/a2.sphotos.ak.fbcdn.net-364-1323840129.5.jpg)

Lotus steering rack in place and excess 914 sheet metal removed.

(IMG:http://www.914world.com/bbs2/uploads_offsite/a8.sphotos.ak.fbcdn.net-364-1323840129.6.jpg)

Lots more room in the car with the cage removed.

(IMG:http://www.914world.com/bbs2/uploads_offsite/a4.sphotos.ak.fbcdn.net-364-1323840130.7.jpg)

Next step is to construct the new cage and start putting the car back together.

Do you think the new "system" will accelerate or slow engine or transaxle removal?
Critical decision: paint the new cage to match the suspension sub-frame, or in a contrasting color? (IMG:style_emoticons/default/biggrin.gif)

The removable sub-frame should make the engine removal much quicker since the I won't have to disconnect the axles or any of that stuff. I plan to add quick disconnects for the brake lines, but I will still have to deal with the radiator lines.

Heading down to Costa Mesa R&D on Saturday so I'll be driving right by there (well, close anyway). Let me know if it's acceptable to drop in. Not sure I'll have time, but just in case...
