The 914 conversion, 3.3 Ltr suby upgrade Options

[mepstein]

Just read through this entire thread again. Yes the mounts are shown in my thread.

Easy way like I said way back when is to use 914 to 108mm adapters.

Stephen - I sold Frank a set of early 911 trans stubs, hub stubs, 5 lug hubs and cv's, so along with a set of sway-away axles, he should be pretty set.

[914forme]

Good to know, well then your good to go carry on.

Will this much of a opening, Flow enough air to keep it at or around the 180 / 200 deg.I intend to cut out large sections of the hood under the grill...

[76-914]

Looks large enough. Don't cut that front hole too large. Any of those support braces beneath the hood going to be cut out? (IMG:style_emoticons/default/beerchug.gif)

[Chris914n6]

Way bigger than it needs to be. Hot exhaust air is only 20% more volume than the incoming air. Plus air rushing over the hood will suck some air thru too.

Easiest way to know is to measure the rad opening (bumper holes) of the car the engine came out of.

My v6 opening is just 7 of the round plugged holes and both horn grilles, outlet is the 2 holes in the floor from the dealer installed a/c. I used a Corrado rad with 2 11" Spal fans back then, when it sprung a leak I installed the Celica/MR-S "performance" rad with stock fans.

My :2cents: don't cut up a perfectly good non-replaceable lid when the wheel wells or truck floor work just fine and keep a sleeper look.

[flmont]

No Sir,.just what ever metal needs to come out, all braces will stay,..

Chris 9146 : my opening is all those holes removed so what 4" tall and 26 " long

I have a large I think its a 3 row Rad. and Ill be using 2 spal 10" fans

$699 HIGH PERFORMANCE AXLE KITS: Good up to 500 hp! Sold per pair.Would these Renegade axle's have the same floating abilities that the sway-away or your turbo CV's axle's have. the 2' margin needed to fit my Air intake is very helpful... Thanks

Can you weld on the original 4 cyl cross member I may want to re-enforce that bar now because the one I had made actually bow's with the full weight of the engine Plus I could use the shift linkage opening ???

I had the open look back when my car was flat black. I liked it and it worked for the hot rod look I had, but when I painted the car I put a stock hood on and never looked back.

V8's need as much cooling as possible. Modern engines not so much.

[flmont]

I understand,But I can get a new hood easier than I could weld up inner fenders,Plus I thought it was said that if you did a trunk floor opening that it got dusty and dirty quickly

[Andyrew]

Cutting the inner fenders are much easier, cleaner, and reversable than the hood. A nice sharpie, a jigsaw, and a steady hand can do the fenders in an hour. It will stay much cleaner in the trunk this way than either the hood or the floor. Also you could take the time and duct it and the trunk becomes functional for storage once again.

All the pro conversion shops go out the fenders now. Fyi.

If your hood is good and clean then be damn glad and don't cut it. They are very difficult to find without rust starting.



It's your car so do what you feel you want most. If your design calls for a hood exhaust then by all means. Just know the fender exhausts are known to be the best method.

Don't put the grille on the hood.....! (IMG:style_emoticons/default/barf.gif)

IMHO.

[flmont]

Well my radiators till upwards to go out the hood

[914forme]

No idea on the axle kit, but then the answer is a phone call or e-mail away.

Go out the fenders as others have suggested. And I bounce off the through the hood idea a lot.

Simple math you only need 1.2x the inlet size to the outlet size.

Most spoilers have an oil cooler opening of 1.5 x 19.75 = ~ 30 sq inches. so you would need 36 sq inches total or just 18 square inches on each side. If you are going full GT size with the bumper match, you just double the size for each fender. Fans and ducting on both sides of the radiator make a huge difference here.

I am pondering mounting the fans in the fender well to make the entire system a negative pressure zone behind the radiator. That is all theory at this point

You can not weld to the stock bar.

PORSTI has a great bar build in his thread.

Well my radiators till upwards to go out the hood

So? When I had my v8 radiator setup it was almost laying flat.. Did just fine for what it is.

[flmont]

Yes 914forme,..Iam trying to do just that and thought I had it worked out until my cross member was bending as my motor was being lowered not by much maybe just 3/4 of a inch but that tells me the bar is not strong enough to hold the engine it wont hold all the road vibrations and ass hauling I intend to do,Right ?? I don't know a thing about metal but it needs to be stronger,.Maybe I could get plate steel cut and then welded..??

[914forme]

Metal comes in various wall thicknesses . You can actually get 1" or 1.5" with a .25 wall. You can also add a gusset to the top to add a bit of stiffness. .25" wall tube will add some weight to your tube section.

I use the Metal Supermarket here in Ohio there is one at 4625 W McDowell Rd #140, Phoenix, AZ 85035 Never had an issue with them here.

Scott could tell you what he used for wall thickness. I know he had an early bar because he got it from me, and he built his own. Part of that is Scott nothing goes unmodified coming out of his shop. And that is a good thing (IMG:style_emoticons/default/aktion035.gif)

[flmont]

Thanks for the Info,..I will ck that out !!

[flmont]

Don't put the grille on the hood.....! barf.gif

IMHO.

Aah come on, it cant look that bad,.I thought it was a Fabulous idea, I don't want big holes in my fender wells,Unless I have no other choice.and I thought this would be my other choice (IMG:style_emoticons/default/idea.gif) (IMG:style_emoticons/default/idea.gif)

Will this much of a opening, Flow enough air to keep it at or around the 180 / 200 deg.I intend to cut out large sections of the hood under the grill...

I also have a flat radiator configuration with an EG33. I used to drive this car in Puerto Rico, ambient temp 85 to 93 all year around (is always summer there), and was consistently in the 180F ( I have never seen anything over 185 unless if I change when do the fans should kick in).

The only thing I hate about this configuration, and make me want to go with the cutting the inner fenders route, is that the hot air will flow into the cabin.
