Crazy 911 question. Fitting a 914 motor!

[jwernquist]

Hey guys..
heres the deal my brother in law is jsut turning 16. And i'm picking up a 911 tub. He spent last summer rebuilding a 914 motor. Obviously his parents dont want the flat six so a 914 1.7 should be slow enough for him. Would we just find some 912 motor mounts? And then work the sheet metal etc?

Anyone ever do this? Oh yeah we were planing on mating the 1.7 with a 915 trans. Any advice out there? On what we will need to do?

Dont worry once hes driving a little bit. We have a nice 2.4s motor for the 911 this is only temporary!!

Better yet, why not find a 914 to put the motor in??? Even having to fix a rusty tub, you'd be in for alot less work.

[Mukilteo911]

sell the 914 engine and buy a used 2 liter or 2.2. They are reasonable used. I have one for 2K. 125 HP will run for years

[Hetmann]

Maybe you could find a 912 tub.

[Tim Walsh]

I'm going to second the flat six comment. Find an old 69T engine and put it in there. THe 2.0T's only make 110, only about 20 HP over what a 912 makes.

Not a crazy question. The factory did it when they came up with the 912E which was nothing more than a 911 with a 914 2.0 engine.

About 20 yrs ago I did it to a 69 911E w/ a 71 911S engine which I pulled, replaced it with a VW 411 1.7 engine. Drove it like that for years and had a ball watching friends reactions when they took it out on the road, amazing torque and response with
the stock efi.

Cheers,

You're pretty much making a 912e. You would need to make a rear engine hanger and some sheet metal to seal up the engine bay.

The bear is hooking the type 4 flywheel to the 915 output shaft. You should look into using a 901 tranny instead, the splines will match up then. Don't know, I guess you could talk to Kenedy about a flywheel, don't know if you just need a 911 disk in the clutch and maybe a different pilot bearing.

I've been working on the oposite, putting a 6 cyl in a 912e. Hasn't been too bad a project.

Uhhh this might sound stupid but ...won't you have to flip the ring and pinion gears in the 901 box or it will have 5 reverse gears? I admit this sounds stupid but I'm just curious.

[DonNewton]

He doesn't need a six, he says he has a 2.4S ready to go. The 901 box was a 911 box before it went into the 914. So, an early (911) 901 box will work just fine, no 5 reverse gears. I'll second an earlier post: buy a 914, put the engine in, and play.

[jwernquist]

Thanks for all the input. Im still going with the 914 motor for now since he does have a fresh one with the EFI. I dont want to purchase another motor aka 2.0 . I'm pretty sure if i find a 912 engine mount i can get this stuff to work right!
It will be interesting. Ill keep you informed.

[stlrj]

The reason I went with the VW 411/412 engine instead of the 914 route was because the VW engine was already configured for a rear mount application, heat exchangers already facing the right direction etc.

I did not feel that I needed to make it any more complicated that was necessary using a mid engine design.

Nothing wrong with keeping it as simple and stupid as possible since there will be plenty of challenges along the way.

Actually i Have a 411 Motor with exaust etc. I was hoping to use most of the components like metal on the 914 motor.
Here's what i have :
1.7 longblock.
2.0 411 w/carbs/exaust
the 2.0 wansnt rebuil but the 1.7 was. I dont know !! heheh What should i do. Not gonna go the flat 6 route. Just not yet. He doesnt need that type of expense or power. hehe

[Zeke]

It's all in the sheet metal. Some of the hardest to find P-car parts include 912E sheet metal for a type 4 motor. Once you find that and resolve the 915 issue, you're on the home stretch. I know this because one of my earlier plans was to buy one of the plentiful early 912's and put one of my t-4's in it. Not as easy as it sounds.

Why not a 901 out of a 911? I bet you could buy the tranny for what you're gonna put into mating the t-4 to the 915. Intruments are going to be an issue or maybe you could drysump the t-4 and use the oil tank guage. Hah!

[jwernquist]

HAhahah yeah im not sure what to do about the gauges yet. Still tryin to figure that out. hehehe

[maxnine11]

Wow, everybody wants more power in their 911...you want less . Would it not be easier and cheaper just to detune the 6 cyl. ??? restrict throttle opening and add a rev limiter. ...maybe cut the electrodes off of a couple plugs..haha. If junior figures out how to defeat those mods,find a set of cams for the 2.4 with badly worn lobes. install cams. If he figures out how to defeat that mod.....he's well on his way to being a bonifide Porsche airhead

I guess you can take that a couple of different ways

I don't think power is the overall issue here. A healthy t-4 motor will power that car to high enough speeds to get killed or hurt just as in a 911. And with any kind of performance exhaust (read louder than a hush) will get all the teenagers hormones flowing. After all, what does rice sound like? Can you say 4 cyl?

No, I think there's more to this.

BTW, put a rev limiter on the t-4. They will spin up pretty good. I had to watch mine w/o the limiter as it would go to 7000 if I wasn't careful. They don't like high 6's w/o real good head assemblies. And the power band is at 5000. But they'll go way up there.

[maxnine11]

ok Zeke...i get it now....they are also concerned about having the 6 destroyed!!??!!
the first car i got to "borrow" from my parents was a '72 Chevelle. 6 cyl., 2 spd.powerglide transmission. I had to get very creative to make that thing squeal

[red-beard]

Let me make a really Stupid suggestion:

Buy a 914 to put it in. It will cost less and the kid will still have a ball!

Ya i know
but the prob is we have the 911 tub. and a 914 and the 914 was too much rust work. Dont want to buy anything else. What everhappened to make due with what ya got heheh NOt go out and by somthin cause it will be easier!!
