No but giving the 2.4 Ecotec 170 hp computer motor a lot of thought . $2200 plug and play straight to the door comes with everything I need .:Shrug:
Fuel who and curve what?? Dude, you just went way above my pay grade! I'm still settin' points! :D
Good luck and let us know how it turns out! I might even learn something! ThumbUp
Well I have it apart.
Looks like it is gonna be a 2276cc or so.
I have ford edis coil driver and coil.
Crank trigger and wheel.
Mitshubishi high impedance 320 cc injectors.
Chevy sensors.
Camero throttle bodies that I ain't too sure about. Might do something else. Wanting to use a Ford idle air valve and it is pwm instead of the chevy stepper motor. The camero bodies have the idle air on the body themselves instead of seperate.
Currently building the controller board.
I have all the code to load on the chip and the software to set it.
Just need to figure out what to set it all to.
I have done stuff like this to other motors.
But not to an old air cooled vw.
I could just do enough math and make a guess and tune from there trial and error.
Or maybe I should get some wide band o2 sensors and just make it auto tune.
O well I will figure it out as I go.
good luck and let us know how it turns out.
all of the sensors , computers, and wiring night mares are why I retired my wrenches to my garage and went to nursing school.
Changed my mind about the Camero throttle bodies. Got some big kawasaki scooter units. With the injector bosses in them. Now to make some custom intake manifolds.

Got a new 86mm stroker crank. Some 5.5 inch long chevy rods. Now looking for some 92mm thick wall cylinders. So it is gonna be a 2286cc.
Damn... Now [I]I [/I]want one! :D
WOW now I really feel OLD. I recently got a '71 single carb 1600 and I ain't used all it's got to offer. But I still remember when I would have wanted one. Boy Howdy, a 1000 miles and I would've been there in the morning. Gas, tires, and tickets. Sure did enjoy it. Which is part of the reason for my disability. But it was a hoot. Boy am I feeling old.
Thanks for your time and the memories.
Bare Frame. Hopefully It will be back together by next summer.

ThumbUp Very nice job !!!
ThumbUp
Thanks!
I have been emailing with Pat Downs.
I am going to be hard pressed to get to my 200 hp goal because of my 4 straights exhaust. He told me without a merged 4 into one collector I will not be able to run the big cam.
Did recommend a more aggressive cam than what I have now.
I am going to study it again. Maybe now I can figure out a place to put a real header.
Good luck seems as though 4 into 1 riding that low with a mid engine is gonna be hard but I think if anybody can do it you will .
Now there is still the Ecotec 2.4 turbo 200 plus . :D LOL :Agree:
Lookin' real sweet! Great job on those manifolds, I wish I had your shop!
I went ahead and ordered 94mm pistons and cylinders. Also an Engle Fk10 cam.
New displacement. ........2387cc
Now to get back to working on it.
Keep up posted Rex ,:clapping: get that thing going may have to go find Asian up in Oklahoma .:D
Sorry.
Has not been a lot going on here so I have not posted either.
I guess I will post up my scattered pile of parts.

This is the upside down and backwards trans.
Normal 1 and 2.
Later style 1.26 3rd from us gear.
0.82 4th from rancho.
3.44 ring and pinion from rancho.
Welded on syncros.
Splined shafts.
Billit side plates
8 bolt carrier.
4 spider
Shortened axle
Disc brake conversion.
[ATTACH=CONFIG]47715[/ATTACH]
It is coming apart to check out any issues.
It has been gronking into 4th. Got to check the bearing adapter and nut at the end of the shaft by 4th. The Splined shafts are not supposed to fit a swing so it has adapters to match the different bearing sizes. My adapters leave no place for the lock tab washers. I suspect a loosened nut. I may have to tack weld the nut.

Drive extension.
The bearing in this runs on grease from a remote nipple.
Gotta check that too.
Feels fine from the outside.
I have not torn these down yet.
My pile is large enough already

Already took three hands and the "pucker method" to stay with it to start with.
I call myself putting enough duration on the cam that I soften up the bottom end. So maybe just normal putt around riding it won't even be on the cam at all.
Putt around sub 3500 at an off the cam 50hp. Then twist on it and in comes the cam at 200 hp all the way to 7500rpm.
The old motor came on pretty low and was "twitchy" to ride sometimes. Fun but scary at times in traffic. I have had a few panic "get on the brake- get the front on the ground- before I run into someone" moments.
The 94mm Mahle cyl and piston kit.
[ATTACH=CONFIG]47709[/ATTACH]
This and the 86mm crank on the other page.
2387cc.
Gonna have a lot of shim under the cyl to get deck height. Crunching the numbers I get almost a quarter inch of shim. Probably have to make a custom spacer to go with the long stroke long rod combo.
A perspective on frame size and weight.

Hopefully it will still handle it.
I am curious about the process of building a front engine VW trike. It seems I've heard it takes two tranaxles, one flipped upside down as yours is. I have old transaxles around and who knows, maybe someday I would attempt a front engine build. Looks interesting. Thanks.
It takes internal machine work inside the case to make it oil.
Rancho will build you an inverted. They are the only ones I know of.
I have full access to a machine shop. So it does not bother me to do heavy modifications.
The normal way to do it is to pull the ring and carrier out one side of the case and stick it in the other. All then is shimming the backlash. No machine work.
I flipped the entire trans to make mine much lower than the car would be.
If you use a full width irs you could squat it down fairly low. If you narrow it then no.
If you want to run a swing then no again.
Bad ass trike company sells frames and drive components for a normal set up.
But mine is 6 inches lower than normal.....lol
[COLOR="silver"][SIZE=1]- - - Updated - - -[/SIZE][/COLOR]
This is what it looked like before I took it apart.
Drain plug is 3-1/2" off the ground unloaded.
[ATTACH=CONFIG]47707[/ATTACH]
Definitely one of the meanest looking trikes around. I don't have access to a machine shop so is it possible to do this without machine work? Uh oh, looks like I may be researching another project.:laugh:
Machine work is a must going inverted.
If you don't have access to a shop then do it with money. Call rancho transaxle.
Best bet is do not invert.
Just move the ring to the other side and do the shim work. Then just live with it being 9+ inches off the ground.
Bad Ass Trikes company has (maybe had, it has been a while ) all the parts to do a normal (not inverted) trike.
Their drive components looked weak to me and I did not trust them. Probably ok for a 50hp stocker.
Mine is a hot rod. Old engine around 160hp.
New engine is going for 200hp. My trans has a lot of other mods inside it also.
How is you weld and fab skills and tools?
None of the vw suspension is usable on a mid.
You will have to buy (if you can find) or build yourself all the rear suspension.
A swing axle is easiest. The swing arms are much simpler than an irs would be.
Mine is a swing and is narrowed a lot.

A bad ass trike company kit build.
Pretty cool. Just not what I wanted.
[ATTACH=CONFIG]47717[/ATTACH]
ThumbUpAre you changing the front , thought I seen a set of rockers for a springer ?
I can weld and fab. I do have a swing axle as well as an 2 IRS trans. So if I didn't shorten the axles the stock suspension would work? The inversion is done just to get it lower? I'd want to keep the build as simple as possible being it would be the first try. I'd be using a stock motor so stock components should work. I just latched onto a good running Manx style dune buggy so of course my first thought is how to make it into trike. The front engine would be interesting project. I am just trying to determine if it would be something my skills could handle and cost would be a consideration also. I'll go to the websites and see whats up. Thanks.
I went to Bad Assed Trikes and I think maybe I am beginning to grasp the concept. The ring and carrier swap changes the rotation, the extra trans case is used to lengthen the trike, otherwise you'd be sitting on the engine. Stock suspension won't work as you said. Am I right so far? I'll do some more searching and see what I can find. Thanks.
Yep.
You got it.
They don't do inverted.
That is a Rex thing....lol.... i always hafta be different.
A swing axle can be squatted some. The wheels camber badly and drive bad.
Squatting a swing means the axle bearings have no oil at all. Pack them with grease and they will last a little while. The fulcrum plates will gall up if you go very far down the road with it.
Squatting an irs would work fine. Might could run slightly shorter axles.
I do not know of anyone that makes the suspension for an irs set up. You would probably have to build that one yourself.
Take all the inerds out of the irs and put in the swing case if it is a 12v case.
Or if not then put the swing side plates and carrier in the irs case. Run the axles straight no squat. It would be the easiest way to go. The swing arms would be simpler to build. And you could narrow it if you wanted.
[QUOTE=slick rick;269290]ThumbUpAre you changing the front , thought I seen a set of rockers for a springer ?[/QUOTE]
Yep..
Making that stainless steel springer I have always talked about. Nothing long. Short and stocky as far as springer go. Going to a taller 90/90x19 tire and single disc. Thinner dirt bike tank and painting it.
Engine is getting fuel injection and distributer less. Bored and stroked some more. Bigger cam. Think I have a set of tri-y headers in my head that just may work.
Hey do you have a set of 1.4 ratio rockers? I could trade out my 1.25 ratio.
Crank hit the cam. Gotta get my lift with more ratio.
I found one that only looks like he used only one trans case. A lot simpler to build but sitting on the engine might be a little uncomfortable. Just kicking it around right now. I'll have to go out and rummage through my junk pile and see what kind of parts I have. Thanks.
[ATTACH=CONFIG]24474[/ATTACH]
No I don't Rex ,, gonna have it ready by spring you think ? We got a ride planned down the trace in April , may see you down that way .

I like the looks of that build VW driver ,,,don't know if I ever mentioned this I was borned in Tocoma ,,,wayyyyy back in 56 !!!!:AGGHH:
I want it back together by spring.
I have a lot to do though.
I have it in the chopper underground biker build off. Maybe that will keep me inspired to get to work on it.
There is not an exit off the trace at vicksburg.
But the trace is only a couple miles away from the house. We run up and down the trace between port Gibson and Ratliff ferry at the northern end of the reservoir.
