3.2 liter install into Huey, ...Suggestions or any tricks/things to be aware of?? Options

[naro914]

Yep, Huey is getting a winter/spring upgrade to it's final (hopefully) engine - a 3.2 liter fuel injected from a 87 carrera. (IMG:style_emoticons/default/piratenanner.gif) After driving a few 3.2's, that was always the engine I wanted to eventually get.

So...all this time I have been upgrading/changing engines that were 1) smaller, and 2) carbuerated. Other than the obvious of check it all out while its out of the car, etc. I know that the best way to make it fit is to flip around the intake.

Other than that??? Anything special I should know, do, forget, etc??

thanks for any help!

Not much to add other than you will be happy (IMG:style_emoticons/default/driving.gif)

Here is a pic from my old six, I knew the maf was flipped and smaller KN style filter, with a small custom bracket to support it.

Practice smiling really big. (IMG:style_emoticons/default/biggrin.gif) You'll need it.

[Frost]

That's going to be a hell of a car when it's done.

Mount the brain as far away from the engine as possible.
Make sure your front mounted oil cooler is big enough. You do have a front mounted oil cooler, correct?
Make sure your oil lines are large enough.
Mount the thermostat close to the engine.

I'm sure there's more but i'm too lazy to read through my build-thread right now ...

Make sure your front mounted oil cooler is big enough. You do have a front mounted oil cooler, correct? Yes, and it's plenty big.
Make sure your oil lines are large enough. Got them should be big enough (see pic)
Mount the thermostat close to the engine. Need one of those.

Huey has gone from a 1.8/4 (which I never had, there was no engine when I bought the chassis), to a 2.0/6, 2.2/6 (Papa Smurf shared his engine with Huey for a while), 2.5/6 (from a black race car I eventually sold), 2.7/6 (current, just sold) and now a 3.2/6.

braided ss oil lines.

IIRC mounted the brain inside, behind pass seat against firewall. I remember it being a PITA to feel the plug through the tunnel but it was done.

[SirAndy]

-12 lines will do. As for the thermostat, let me dig out my build pictures ...

I mounted the brain all the way in the front under the dashboard. The 3.6L harness was long enough to do that without cutting.

The thermostat went into a box

[naro914]

nice. thanks
what pisses me off it I JUST carpeted the entire inside of Huey. Did a real nice job at it too, but I'll end up having to pull a lot of it up to run the harness and mount the brain somewhere.... Damn!!!

Yeah, almost forgot about the fuel pump too. Not sure where to mount that one.... plus I need another fuel line through the tunnel.

Regarding mounting the Brain, I just cut the round indentation out on the passenger side firewall and ran the cable across the back and mounted the brain behind the drivers seat with one of the screws that holds the back pad on. Did not cut or modify the cable. Fits perfectly!

Yeah, but I have no back pad. I covered the back fire wall with sound deadening, then carpet. Fit everything perfectly including the floors under the seats. And I used A LOT of adhesive. I didn't want any of it pulling up.



I'd prefer to put it under the passengers seat if possible because we never move that . My wife pulls the drivers seat all the way forward, and me all the way back, when we drive, so I don't want the brain/cables exposed if not necessary.

How about putting it in the rear luggage comparment? That's where I had the MSD mounted.

[ClayPerrine]

I did a 3.2 conversion for a customer, and mounted the brain in the back trunk, along with the DME relay and a fuse block for the FI. The customer wanted the battery back there too, so I added a battery cutoff switch. Made a nice, clean install when I was done.

You will have problems with wire length. The harness for a 3.2 is way too long for a 914, and the connectors are in the wrong place. Plus you have to run a second wire for the tach. I have the diagram somewhere that I drew for the customer so he would know how to troubleshoot it when it broke.

[naro914]

way too long may not be a bad thing.

I made carpet between the seats under the armrest to be removable - velcro on the back so if I ever have to access the shift rod for adjustment or something I could. If I only have to remove the carpet that covers the front half of the tunnel, I may be OK there. then I can run the harness along the same path as the current wires, and mount the brain under the dash like Andy.

Since I use an autometer tach, I have a separate wire for that now. Not sure if that will work, but there is a wire.

[pcar916]

I have one simple design rule on my car. Everything has to be quickly accessible. I mounted my DME behind the driver's seat with the DME relay right there as well. This would mean you'd have to find somewhere to snake the 3.2 harness... maybe battened around the engine compartment before it gets into the cockpit?



Good Luck!

[naro914]

Anyone got a wiring harness for a 3.2, the one from the engine to the ECU?

[Eddie914]

I have to check. I might have the wiring harness. I know I have an ECU and some misc. FI plumbing.

The 3.2 I purchased to replace the 2.7 in my teener was missing the intake manifold. I was hoping on going Motronic but the Webers from the 2.7 bolted right up to the 3.2 and have run quite well. It would run better if it was driven more. I need to clean the idle jets too often due to old damp fuel.

Will you be using a 915 or 901(914) transaxle? Kennedy has the required parts to mate the 3.2 to a 901(914). I am using a 901/914 trans and have only worn out one in the last five years of track use.

I switched to 944 CV joints used with modified 914 axles.

Good Luck.

Eddie

[naro914]

Hi Eddie,
I'm using a 901/914 tranny. The car will be used most for street and autocross so it should be just fine.
I have some sort of 930 CV joints and axles - or so I'm told....

I bought the 3.2 engine, and when it got here, it had the motronic unit, but not the harness that attaches it to the engine (and all the other connections the harness has). The guy that sold it to me said he would make good on it, but he hasn't found one yet so I figured I would start looking.

Know anyone looking for 40 IDS carbs? I'm selling those from the 2.7....

The autometer tach won't work without a tach adapter of some sort. The 3.2 uses a tach that takes a low voltage signal from the ECU, not a high voltage signal from the ignition system. If you use the tach signal from the ECU, it won't output enough to drive the tach. If you try to take a signal off the coil, you will fry the ECU.

Get the tach that is supposed to come with the 3.2 and run it. Simpler, and easier to hook up.

Thanks Clay, great advice. Is it 3.2 specific? or is it 911 FI system specific? I think I actually have one from an older FI 911 engine.

It would look better in the dash anyway (IMG:style_emoticons/default/smile.gif)

The older CIS systems used the early tach electronics. You need a 3.2 tach to make it work. You can use a 3.6 tach, but you end up with a bunch of lights you won't use.

I am looking for the diagram I drew, I figure it might help you. But I am having trouble with my primary desktop computer at home, so it may be a little bit.
