My 3.3L Subie Conversion Thread, Got me some 914rubber stuff Options

[rnellums]

Update...working on the "heater core in the fresh air box". First I had to take the wiper assembly out to lube it and change the rubber mounting bushings. Dang that thing is not fun to reinstall!

Here is the modified airbox.






FYI the STOCK mid-90's mustang heater core is a little too thick to fit inside the fresh air box. I had to modify mine a bit. I'd go for the thinner aftermarket one if you're going to do this.

I love what you did here Chris! I'm going to be working something similar in the next month or two, but I may try to make a custom core to size. Love seeing the ingenuity!

[Chris H.]

Yes you definitely want one that fits in the box, preferably one that exits out the side. In a stock 914 everything in that area fits PERFECTLY without a mm to spare although it doesn't look that way. Mine was a PAIN IN THE ARSE to install because it's so close to the fuel tank filler. I think an aftermarket Mustang one that is thinner might work. You could trim off the circular piece above the fan right down to the box (which is necessary for any heater core) and then take it to an auto parts store and have them find one for you.

Ah....hindsight...at least it's useful for others... (IMG:style_emoticons/default/biggrin.gif)

So "how's it going" with the MS3X install? I think it's best summed up by the first 43 seconds of this clip.

Bob's been helping me a lot but the MS forum has been poor. I think I might post some stuff here in case anyone has other ideas...

Please do. I have an older MS installation on my 3.2 twin plug, cammed build with EDMIS and PMO throttle bodies. I've had some of the inevitable bugs to work out after the masterful build by Series9 (Joe O'Brien) that I could share. I've been thinking of improving the current setup with a Clewett TPS (basically a "wide band" TPS) for the PMOs to take advantage of the Megasquirt ability to do ITB tuning maps which is a blend of MAP at lower loads and RPMs and alpha-n under loads/acceleration. I want to get rid of my backfire issues and improve performance. It's complicated!

Wait. So the solution is to shoot it? Or just threaten?

Your spoiled by this forum. I'm on lots of others and this place hands down has much less of the (IMG:style_emoticons/default/stromberg.gif) factor. I can name a few others I never go back to., unless I really must. (IMG:style_emoticons/default/dry.gif)

Post away I will try to help all that I can, you need the coil pack back? Or are you running the coil on plugs still?

Yes I AM spoiled by this forum and the people. Totally agree. Bob has spent HOURS with me but he really didn't use MS on the EG33 for too long before switching engines plus he's 700 miles away. And MS3X is slightly different than MS2. I'm sticking with COP so we're all good on the coil pack (for now at least (IMG:style_emoticons/default/wacko.gif) ). So are you buying Bob's old car? PM me if so. I'll tell you all about it.

MadSwede, will do. Post whatever you want to share! The firing order on the 3.3 is the same as the 3.2. Might be able to adapt some tuning. BTW you should have heard the backfire I got when I tried to start this SOB. Luckily the engine was not cycling at that moment and it came out the exhaust. It was right after I stopped cranking it. Sounded like an M80 going off. kaBOOOOOOM.

Kent's what's wrong with your car?

[76-914]

Well let's just say my last diagnosis was completely inaccurate. IOW's, I was (IMG:style_emoticons/default/sheeplove.gif) wrong. I'll detail it in my thread so others won't make the same mistake. I will be using the other half of that roll of hose soon if just to clean up the front trunk area. (IMG:style_emoticons/default/beerchug.gif) EDIT: I didn't answer your question, "What is wrong with your car?" Answer; the builder! (IMG:style_emoticons/default/sad.gif)

[Chris H.]

Ah...still getting a little hot? It'll cool WAY down with the 1.25s. Just try not to have any detours or bends in the hoses. Straight back...think about going underneath this time...way less drama. I can send pics if you need them.

BTW I REALLY want ITBs but the cost is just too much I think. Would look SO GOOD too.

Yep. Engine and radiator temps are perfect but the radiator heats the gas tank. Turns out I'm not the 1st. Tony (cracker) had the same problem. He gave me several pointers. The best being; start by enlarging the wheel well openings!

[mgp4591]

Has anyone done any successful ducting to exit out the wheelwells? That seems to solve alot of the problems in other cooling systems in exotics, etc. It would isolate the heat from the gas tank and anything else much better and could be relatively light if it's done correctly.

[914forme]

Yes several examples.



As much as I like the above unit it is for a oil cooler. I (IMG:style_emoticons/default/wub.gif) (IMG:style_emoticons/default/drooley.gif) (IMG:style_emoticons/default/aktion035.gif) (IMG:style_emoticons/default/pray.gif)



This is for a Radiator

[mgp4591]

Those are great examples but the radiator is what we're concerned with and while the carbon fiber is really cool, most of us don't have the skills for that so I'm looking for possibly a sheet metal creation of some sort. I'm currently working on the brakes and suspension but when I get to that point I think I'll need to come up with something functional for ducting. I'll probably be making some bends with the hose so I'll need all of the help I can get.

I've considered using canvas w/ metal framing if I end up going this route. Quick and easy to fabricate or remove. (IMG:style_emoticons/default/idea.gif)

^Jon, do you have links to this setup configuration and more details about the TPS?

Sounds like an old airplane fabrication method, dope and fabric.

Mike,

I think he is talking about the Hall Sensors for the PMO carb. TPS can not be a wideband. yOu could increase its ability to be more precise ultimately it ends as a voltage reading.

You could build the shape out of canvas like you said and then coat it with fiberglass and polyester lamenting resin. I had a fiend do that to build a kayak when I was 11

You would have an item to sell if you used a standard cooling that guys building any water cooled 914 could use.

I had heat blowing into my cabin in my old SBC set up in the 70s. “If you want to run cool, you got run on heavy heavy fuel” No I just always thought it was not a good idea to warm up the gas.

[Chris H.]

Ruby914 made that carbon fiber masterpiece. Maybe he would be willing to make some fiberglass copies. Kent I think the thing you need to do is get all of the water lines away from the fuel tank. The larger ones would be a bitch to snake through your longs and then up through the body. I'd just go down the center of the car underneath like I did. None are near the fuel tank even though it looks like it. You could wrap the ends that will be inside the front trunk to keep the heat down too.

Hey Mueller, the latest MS manual has some good info in ITBs. Download the "setting up" manual here and start at page 64:
