No real progress. Waiting on the engine adapter.

Manifold Flanges came in, new hood shocks, window seals and a Jegs heater core.

The heater core is bigger then the dimensions lead me to believe and it's kinda janky.

In other news is 9 degrees.

Im helping with the fabrication and electronics on the project. Almost have the megasquirt3 finished up, just waiting on two transistors that were mispackaged in the kit. This project will be using quite a few of the MS3 options such as: Full 4channel VVT control (Dual AVCS), 3-wire bosch Idle valve control (stock Porsche IACV), Oil temperature and Oil pressure logging, Oil Pressure vs RPM warning curves (using stock oil pressure warning light), Vehicle Speed input and gear detection, Stock VDO tachometer control, Radiator Fan Control with automatic idle up and air conditioning influence, external map sensor usage (using stock intake mounted MAP), Air Conditioning control, Dual channel knock detection using the stock knock sensors, and also analog gauge control which will feed avg fuel economy readings to one of the stock VDO gauges.


Heres a vid of the analog gauge control. This gauge was originally used for the dry sump oil tank level but that will be gone with the subaru engine. This could be used for pretty much any calculation/sensory data you want. Ethanol(e85) content percentage, average fuel economy, boost/vacuum, knock, accelerometer, air temp, egt, etc***8230;.


And here's a pic of the megasquirt on the stim

I somehow missed this thread, but... awesome. My thinking is EXACTLY the same as you. I got my car to DRIVE not toss a huge $$ lower hp motor in to be "correct". I owned a '03 911 turbo x50, and I need mine to be that fast.

Do you really think your 915 can handle the power? You are moving at about the same speed I am on mine, but I'm glad to see someone else going down this road. I will post a thread when I get time, but I am planning to do a eg33 and then install a "built" eg33 after my proof of concept is working. Random goal is 500rwhp and 2500lbs.

I plan to use a subarugears setup, and possibly run a microsquit v2. I'm rather stuck on the ecu stuff, and my car currently has a vortec 4.3 v6 engine in it with a late 80s 915.
The car is a '71 911t all steel widebody

keep it up and I may be in touch.

Yep, total weak sauce. I mean, it's only the lynch pin of the entire thread

It's hard to say. Most of the forums are horrible sources for reliable information. It's constant hearsay mainly based on "well Porsche said".

Early magnesium case units are defiantly weak. But I have the later Alumium version.

In theory an upgraded side plate with the larger 930 bearing, a LSD and oil cooler should make this a stout transmission. That adds up quick and still looking at other long term solutions. G50s are bonkers expensive, 930s are only 4 gears and the late model 6spds don't have starter provisions.

Yeah winter and everything else gets in the way. Adapter plate is in so progress should pick up.

The plan is to have the EZ36 in and running and tuned. There is a potential for high 200's whp which should be fine on the 915 trans.

Once the cooling and havc systems are proven out, and my wallet recovers, turbo/transmission options will be evaluated.

Talk about about a Frankenstein! At least should have the cooling system ready to go.

KPACZ did a EG33 swap in a 911SC.

Why not run a Subaru 5 or 6 spd with the Subarugears reverse R&P?

The Subarugears Kit is $1,900 and the Subaru 5spd is significantly weaker then the 915 transmission. SG also does not make a kit for the 6spd. Then you'd need all the fab work and custom axles to run the Subaru transmission.

Even if SG made a 6spd kit that would still be $1,900 + $2,500-3,00 (trans) and custom axels. I can get a 930 4spd for that.

The KEP adapter plate is the way to go for this type of project.

I disagree.

They sell 930 adapter flanges, and the later wrx transmissions seem to hold hp rather well. Keep in mind they are using AWD and so the drivetrain loss is higher than with rwd, and the teeth are normally ripping off the gear. I believe that the 915 trans is only good for around 250rwhp and I didn't see the point of purchasing the kep adapter for around $1k when I would just be upgrading in the future.

I am specifically referring to the 08+ wrx transmissions, and yes it does have a few fab (shifter setup) hurdles, but I believe I can handle them.

What hp limit do you think the 915 can handle? I am expecting my NA eg33 to put out around 250rwhp at a minimum and spin to 7500rpm easily ( it has a stage 1 chip on the stock ecu). I may go ahead and try the adapter route to save time... I seem to be running short on it lately

KEP adapter is only $550.

I don't see how putting all the power into the front differential is going to improve reliability. I feel it would actually stand to strain it more.

As I stated, lots of hearsay on the forums regarding the 915 transmissions. I've seen them bolted to LS1s and survive. I've seen them bolted to 3.8s and die.

Renegade Hybrid believes 450bhp is the upper limit while others have stated 300 ft/tq at the wheels is the max.

Another way to think is if you grenade your WRX transmission and SG gears you are out $4k. If I pop my 915 I'm out less then $3k.

At your power level it will just be preference. 915 is very archaic shifting with a cable operated clutch. Subaru is obviously going to have tighter synchros and smoother shifting.

Factory writing from early turbo development indicated the 4speed was necessary as the 915 could not be modified for the Torque/Hp capabilities of the turbo motor. Keep in mind they built the 930 project to compete in group 4 and at that time the 3.0 liter turbo in group 4 development was getting to 500HP. The 930 4 speed is good for well over 700HP using a trans oil cooler for extended track time. I personally would go to different R&P for reasons outlined in my last post or gear changes in the 930 trans as it will cause no other expensive alterations. If you can stay away from more HP mods a 915 with some upgrades as RarlyL8 alluded to should work as I think he has modified his 915.

Good points, and I didn't realize they were that cheap. I was under the impression it would be 1k for the flywheel,clutch, and adapter. The price point is really making me think I may just try this... based on my 915 case it's from a '86 911. It would save me significant time in fabrication.

Thanks for your info and I hopefully can refocus on my project soon. My high mileage DD wrx wagon decided to develop a knock over the weekend, and that is now my #1 project.

Fast forward a few months.

He buys a very similar car (obviously in his price range) much to the chegrin of the rest of the forum. Car blows up. He asks for help. Hilarity insues. My quote appears. A while later this thread appears.

Default EZ36 Swap into Porsche 911

Windshield is out. Dash is being obstinate. Whole car is going to be re-wired with an actual harness (instead of a rats nest) and modern fuse box. March Madness / Spring Fever has destroyed all motivation.



Test fitted the KEP plate, nice setup, fits snug.



Also found the missing link.



Life just got that much easier.

Sounds like you need to get over this forum white knight mentality. Who cares what Corbic has allegedly said or done, from my experience with him on Zilvia.net he's been a staple quality contributor. This thread also appears to be all business, so what gives?

TLDR: stop ****ting on his thread.

White knight mentality? I do not think you know what that means.

LIES!!!!!

Two of the studs just spin in place. Le Sigh.

Decisions been made to just toss all the factory wiring. Their really is no existing "harness". It's a rats nest of 50's wiring with individual wires all running back to a fuse box where they are screwed into.

Waiting for it to get up around 50 degrees. I'll roll the car into the drive way and strip it down. Pull the fenders, rest of the glass, interior, and remove the fuel tank.

German Horror Movie.



The other distraction...

interesting looking build! We put a turbo'd EZ36 into my old legacy, getting the ECU to run it was a pretty big job but got there in the end. Good luck with it all!
