Converting to a 914-6, Back yard Bob's (Dan's) way Options

Don't thank me just yet Trekkor, wait until you get the prototype bell crank I am sending you. (IMG:style_emoticons/default/happy11.gif) (IMG:style_emoticons/default/happy11.gif) (IMG:style_emoticons/default/happy11.gif) (IMG:style_emoticons/default/happy11.gif)

So the 914-6 project is essentaily a done one, thus some of you know I am starting on a 914-4 project for my wife. Both cars are really "ours" as "we" take them places. Although she can't do 99% of the work on either of them, I think she likes to just be involved, which rocks. (IMG:http://www.914world.com/bbs2/html/emoticons/mueba.gif) So here is a picture after I lowered the 914 and added rear wheel spacers to take up the space still left in the rear fender well. I also hand cut out my 914-6 2.2 stickers. I think they look good. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

Signal Orange, my favorite color. sixnotfour on the club here found it for me in September as a lonely sitting in someone's field 914-4 1.7. I did the conversion in a rush (6 weeks) from dented front fendered stock 914 to what you see there. Then we drove it to a PCA Whistler event in Canada. It also has heater boxes I made myself. I recently added heat sheilds to them because they would cool off too much when going over 60mph. Two electric fans run through my heater tubes so you get massive heat even at an idle.

Can you tell I love my car? (IMG:http://www.914world.com/bbs2/html/emoticons/wub.gif)

Very nicely done... (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

And thanks for posting the steps needed to convert to a -6... (IMG:http://www.914world.com/bbs2/html/emoticons/mueba.gif)

Tell me more about this... Inline fans? Pictures?

I will get some pic's of the system set up. I used two 914-4 electric fans mounted above each side of the trans, then ran two "tubes" I welded onto cheapo bursch headers. Later added a heat sheild to one side (testing heat loss at speed). Dang, the work awesome! But you bet, I will take some pics for folks soon. I have heard we got a nice dig camera for X-mas.

Ya Dan, I wanna see yer heater also. It sounds simple and effective. Odd that you are actually trying to keep a part of your engine warm for a change. Does the heater system cause the engine to retain anymore heat, dissipate meore heat, nothing, both, leave me alone and go away?

[Trekkor]

Dan, as soon as you mentioned inline electric fans, I right away thought of 12v marine bilge blowers. They really move air and are pretty quiet and cheap. (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif)

I'd like to see your heat exchanger design. I'd like to build some myself.

Not to worry oh Evil one, pic's will come, but probably not until after X-mas. I purposely added a heat sheild to only the drivers side so I could take pic's for 914'ers, one side done, one side half done.

No heat added to engine compartment at all. So far the only bummer is they probably wiegh close to what the factory heater boxes do. So no real wieght savings with my system. But it works great and I am sure my design could be improved upon by others.

I thought of that as well and someone could probably use them after seeing how I grabbed heat from my headers. I just used 914-4 heaters I had laying around from previous conversions. I always pulled the elec fans out and just boxed them. Had like 6-7 at one time. I think I have one that doesn't work, one that does and 2 I put on my 914-6. I want my camera now so I can so you guys what I did! (IMG:http://www.914world.com/bbs2/html/emoticons/boldblue.gif) Time to go snooping under the tree. (IMG:http://www.914world.com/bbs2/html/emoticons/happy11.gif)

[Root_Werks]

Well, figured out how the new dig camera works. I just jacked up the car and laid on the ground to take some pictures of the heater and how the 914-4 rear tin works with the 914-6 set up. So my angles on my shots could be a little goofy. (IMG:http://www.914world.com/bbs2/html/emoticons/rolleyes.gif)

This first one shows the left(drivers) side of the 914-4 tin. There are two things you need to do on this side. One is bend up the tin around the radious of where it sits on the bell housing. If you just flip the tin and set it on, it will be off center to the left too far. So you have to take and cut or bend ( I just bend ) the tin a little, not much so the tin sits center. You can do the fitting after the engine is installed or before. Doesn't matter. If you fit this rear tin piece with the engine out of the car, you won't have the body gasket to help center it with. So I install the two 914-6 side tin pieces to help show where center is. Once you get the tin centered, you can mark a hole for mounting. You can see I just used on bolt to mount on the left side. You don't need anything more than that.

Oh, you can also see part of my heater tube welded to the bursch headers. Not in this picture is the electric fan. But more on that later. (IMG:http://www.914world.com/bbs2/html/emoticons/sawzall-smiley.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif)

[Root_Werks]

Derr, how about a picture.

The red arrow shows the part where the tin needs to be bent back a little and the blue arrow shows about where the mounting bolt goes. just behind the heater tube out of sight. Sorry about that. (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif)

[Trekkor]

I'm right here scarfing this up (IMG:http://www.914world.com/bbs2/html/emoticons/chowtime.gif)

[Root_Werks]

Now the right (pass) side I F'd up on. It should be mounted higher than this. Another reason it is better to fit this piece when the engine is hanging in the car. This shot you can see a little better I just drilled one mounting hole. Works fine, but one of these days I will go back in and raise it up 1/2" so it touches the body gasket. (IMG:http://www.914world.com/bbs2/html/emoticons/rolleyes.gif) The only thing you need to do on this side is drill one mounting hole and drill out a larger hole for the throttle rod assuming you are using either the stock 914-6 bell crank or my superior 914-4 to 914-6 bell crank kit. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) The larger hole is not an exact science, I drill probably more than I need to, push the rod through, dang, a little more off the side.... fit again sort of thing. (IMG:http://www.914world.com/bbs2/html/emoticons/sawzall-smiley.gif)

[Root_Werks]

Actually, let me add some more to this picture. I circled where you have 3 threaded holes in the cam cap to choose from. I should have drilled the top one. Note my mounting bolt is almost not on the tin. I should have raised it up just a little and used the top mounting hole.

Also, I circled the bell crank throttle rod. You can't really see the hole I made all that well, but you get the idea.

Hey, it isn't perfect, but it is free and fits pretty dam nice if you don't rush like I did on this one. I have done this a couple of times and have had better fits than this. I shouldn't have rushed. But I was out of time when I did this.

[Root_Werks]

Sort of moving along to the heater set up I have. one fan mounted on each side. You can see the fan and the tube as it bends up from the headers. What I used to hang both fans was an exhaust hanger from a local FLAPS. I welded it onto the body of the car adn just bolted the fan on. Done deal.

[Root_Werks]

Here is a better shot of the piece of 2 1/2" exhaust pipe I welded onto the headers and the flow of air. This is the right side heater tube with no heat sheild on it. In town, the tube retains heat and works awesome. When you pick up speed, it cools the tube down more than I like. I will show a picture of the left side tube/heatshield next.
