Awesome man. Here I'll embed it for you....no spaces between the embed code and the brackets. Spaces there are usually the culprit.

sounds like a very fun project you have which is about to go under the knife to make even more fun (IMG:style_emoticons/default/biggrin.gif)

yes, Tarrett front and rear. the front unit has been on for some time but the rear is sitting awaiting install. they wevo brackets the Tarrett bolts to in the rear need to have some fiddling before i can weld them to the chassis because the chassis pinch seam is in the way and was not the case for later 911's. i'll get that install after the rest of the brackets are fab'ed and axles made. leaning towards using the Subaru to 930 flange i have and run the 930 cv's vs subaru cv's. still debating.

Received an order of OEM hardware to bolt the flywheel and pressure plate and clutch disc alignment tool as well as proper bolts for the transaxle to motor. Bolted everything together and slide everything back in place. Needed to trim here and there around the stock suby starter and for the stock suby clutch slave. Looks like she was born there. Made a little adapter to connect the Subaru shift rod to the Wevo shift coupler so I can use the Porsche shift rod (will likely need to be shortened slightly though). I’ll start on the pedestool for shift tower soon. Started in next project…new pedal cluster for hydraulic clutch and improved braking biasing. Need to make a run to get some material and start fabricating!

finished up the shifter pedestool, Tilton pedal cluster mount and modifying the shift rod. need to order 930 CV's then take measurements for 930 to 912 axles and place an order with Sway Away next week. i think the spline count and diameter of the 912 is the same as the 914 but not 100%

Man...I keep going back/forth about the Tilton pedal cluster. seems like it'd be a little cramped in the 914, but honestly the 912 looks even more cramped!

Great build man.

For reference, I am 5' 9" and medium build and in the same seat w the OEM pedals I felt most comfortable in the most forward position and w the Tilton, I'm one maybe two seatings back and don't feel cramped at all.

Nearly done plumbing and ordered a custom throttle cable from pegasus which i'll have to add an 8mm barrel to one end because they don't apply have them and i'll run it thru the tranny tunnel to a bracket and attach to the tilton.

getting down to a few final details I've been curious about whether 912 axle splines are the same as 914. If anyone has them around, I'd be much obliged if they could post up.
912:
spline count 25
outer diameter 27.2 cm
inner diameter 25.5 cm

I'm prepping info for a custom pair, 930 inner spline and 912 outer and
total length 38.5 cm
or suby inner and 912 outer, not 100% yet

been a while lurking and wrenching until i had anything to really substantial to post

-rented a brake flare tool from FedHillUSA and enough lines and fitting to essentially redo all the brakes lines. got the Cunifer stuff which is so easy to work with.
(IMG:http://www.914world.com/bbs2/uploads_offsite/iwolfe.com-5340-1397919069.1.jpg)
(IMG:http://www.914world.com/bbs2/uploads_offsite/iwolfe.com-5340-1397919069.2.jpg)

-got a set of VB911R rear calipers and Porterfields all around from Eric at PMB, things are sweet.
-designed a VSS trigger wheel since 2011 trans stopped using the internal one to the tranny of course... (IMG:style_emoticons/default/headbang.gif)
(IMG:http://www.914world.com/bbs2/uploads_offsite/iwolfe.com-5340-1397919069.3.jpg)

-had Mario and the dubshop laser cut it for me and then tig it to the boot flange
(IMG:http://www.914world.com/bbs2/uploads_offsite/iwolfe.com-5340-1397919069.4.jpg)

-lubed and bolted the 930 CVs and Sway away axles up
(IMG:http://www.914world.com/bbs2/uploads_offsite/iwolfe.com-5340-1397919070.5.jpg)

-fund a early '66 single master reservior and ran 7mm hose to the masters
(IMG:http://www.914world.com/bbs2/uploads_offsite/iwolfe.com-5340-1397919070.6.jpg)
(IMG:http://www.914world.com/bbs2/uploads_offsite/iwolfe.com-5340-1397919070.7.jpg)

-filled the trans with Motul 300 75-90wt

-bleed the system and since wife and kids were out of town, no one around for a leg work out to pump for me so i got a Motive and love that thing.

-burped the coolant system, pita

-turn the key and she started up after her winter slumber (IMG:style_emoticons/default/biggrin.gif) To my delight, clutch engaged, went into gear and pulled right out. but after a few feet i heard a POP and i stopped, pulled forward and POP again, i thought $HIT i broke a cv! what happened was some bubble wrap that the calipers were shipped in were under the car when i was pulling out (IMG:style_emoticons/default/happy11.gif)

anyway, slow short jaunts around the hood and everything seems to be fine. gonna have to get use the the shift pattern now lol the trans shifts oh so buttery smooth!!! just a nudge and click, click, click.

at this point, the only thing i'll need to redo is the brake masters. they are too big of a bore and the pedal is just too heavy and almost no stroke. im currently running 13/16" and i think i'll drop it down to 7/10" and that will give me better pedal feel i think with the 48mm piston SC calipers fronts and 38mm piston caliper VB911R rears.

Thanks man, lots of fun so far. Starting to venture farther and push her harder (IMG:style_emoticons/default/smile.gif)
Been pm'ing DBCooper and decided to order 5/8" bore masters because of the significant amount of pedal so I'll report back on the differences.

Is there a way to NOT hear the blow off valve?
A muffler of sorts?

Also, could you please show details of pyour radiator?
Curious about venting, fit etc...and plumbing.

One could set it up so you would not hear much of the BOV. My BOV however is vented to atmosphere, hence the whoosshh. When/If i get tired of it, i can port it to vent to the inlets side of the turbo. that would 'muffle' the whoosh.


Regarding the radiator, check post #22, i have photos of the rad mounted and how its exhausts. then i enclosed it so it would keep hot air out of the truck area. it vents thru the stock 911/912 gas tank area. essentially no cutting except for two 6"x12" holes in the nose and the holes in the front bumper, kinda like a stock oil cooler opening.

i ran steel tuning along the pinch seem under the car similar to how oil lines would be run

im happy to more details for clarification.

one thing ive been psyched about is no leaks from motor or trans...sure the whoosh puts a smile on for sure, but the little things like a drip free floor just does it too (IMG:style_emoticons/default/biggrin.gif)

DBCooper: reporting back and the swap of the master cylinders to a 5/8" bore feels much better. longer though and much less effort.

edit: too spongy (IMG:style_emoticons/default/sad.gif) gonna go back.

Good to hear. My masters are Howe because they're the shortest, leaving the most legroom. I'm 6-3, size 13 shoes, so need it. Unfortunately Howe doesn't make a 5/8" version so I need some other solution. They've said they might be able to make me a custom one (I need to follow up) which would be easier than moving the pedals. We'll see.

I think you'll like that longer throw. My younger son races bikes, and have you ever seen the sportbike guys do stoppies? They have the same, what they call a "long lever," that gives them so much control they can stand the bike on the front wheel with the front brake. So there is a longer stroke but with a lot more control.

Rich, you can simply route the blowoff back into the intake, no big deal. I can still hear it a bit through the air filter but it's pretty muted. I could muffle it further, I guess, but it's not nearly irritating enough to make me feel I need to change anything.

Matt,
I'm lurking (IMG:style_emoticons/default/wink.gif) Thanks for the kind words. I've since installed front/rear calipers from Eric and done a corner balance in the garage along with string alightnment. Drives great and love the trans. Did my first AX with it this past Sunday in Marina but lots of work to do on the drives skill level and need to play with my set up, some push on turn in and a little bit of 3 wheeling on hard/fast right hand turns. Gonna have a pow wow with a friend who I respect to give me some suggestions. It just keeps getting better and better (IMG:style_emoticons/default/biggrin.gif) hopefully my driving will too.

Right on! I think you should bring her out to a meet one of these days. Would love to see it in person.

Did you set this up with the intent to race, or street track?


Pushing into the corner is usually pretty easy to solve.
