Subi In sandrail...

Iknow im in the wrong place but ive looked eveywhere else with no help. What im looking at doing has been done but finding the guy who did it has been a dead end. I own a 2 seat seat midengine sandrail, presently powered by a 2332 vw. As everyone here knows the two engines share a few similarities....anyhow, to the point. I know a guy who took an EJ22, removed the intake, built some new manifolds and mounted twin 44idf weber carbs on it. He then used a distributor from another vehicle and adapted it to the subi engine. He compared the way to ran to a "very angry well built vw"...ie 2276....2387 etc. I know there are plenty of options with the 2.5 2.0t...aftermarket computers.....ive seen some wild subi's in sandcars and theyre everything a vw has always wished it was!....I like the idea of the carbs for a few reasons.....mainly the cost and simplicity of no electronics, not to mention there are lots of 2.2's that can be bought pretty cheap. My biggest issue here is making a distributor work. If I can get that part figured out im set....anyhelp here????Thanks in advance for any help....I also was directed to this link where a ej25 is used with weber ida carbs??????http://www.projectaerosol.com/porubi/

Don't know about ej22, but i'am building sand rail with a ej27 mid engine.

Ran into a bunch of guys last summer in Flagstaff running ej27 in sand rails with carbs and turbo's," old school ". They took their distributors apart and machined them to house the internals of a chey six cylinder "hei" unit ,

rotation is opposite direction. It can be done on four cylinder too.

Monstaru has talked about a carb'd/disty'd EJ using an Escort distributor driven off of the back of the (US) passenger-side head. Sounds like minimal adaptation needed.

i adapted an escort or exp disty to fit the end of the camshaft on the passenger side of the engine.

very simple

i am still trying to get around to building the intake.i really do not want to outsource it .so have been trying to find the best way of accomplishing it myself.

pm me and i can send some other pics than what are on the website.

On building your own manifolds, I guess what I would do is make templates to fit the bottom of the carb and the mounting pad on the head, carve them from 3/8 aluminum, and then find some thick walled aluminum tubing to make the runners. Thick walled so you can take a die grinder and sort of hand shape the ports. Or something.

 

It makes sense in MY head...

I believe the porubi guy used megasquirt to run the ignition. the webers appear to be set up as carbs tho. as you can see he is running some sort of distributorless ignition. myself, I would have used some tumble valves from a wrx(3/4 throttle plates between the head and mani that also houses the injectors- look em up on nasioc) converted into ITB's since they bolt to the phase II heads.

 

if you were to go to the trouble to do all the work that involved with a swap like this, could you do it with a SOHC ej25? you can find one for like $500 if you look the right places. more cc's, WAY better heads(outflows an LS1 in stock form), capable of 8k rpm in stock form, etc. the principal with the distributor would be much the same but maybe the practice would not I dunno. monstaru?

 

as far as fabbing the manifolds, I'd just do em out of steel. trace the gaskets on some 1/4" plate, put a couple pieces of tube between them, you get the idea. aluminum would be bad rump roast if you have those skills/equipment.

personally I'd never bother to convert an ej engine to carb. ITB's yes.

Hey everyone..its been months since ive been back. Ive researched my rump roast off as to how to set up ignition on a 2.5 without a computer. I did get a reply from porubi who aparently built his own setup...im pretty good but not that good:) Electromotive makes a stand alone dis that I could make work however its like 7-800 bucks. I dont have a problem spending the money but im still experimenting and still unsure how this thing would compare to my current engine once I did get it up and running. I recently got my hands on a ej25 dohc that had been overheated. I got a manual and just for kicks to get familar with the engine I tore it down to a short block. These engines are cool, everything is labeled where it goes! I think the engine may have gotten a little too hot and may be scrap but the price was right to get to play with one if nothing else.ANYHOW....ive heard of guys converting a ford dist to work on an ej22, ive also read about guys running a 2.5 block with 2.2 heads????So could I run 2.2 heads and adapt a disty to take care of my igntion issue and at the same time gain a little more dispacement? If so which heads would I need to get my hands on? Im bound and detemined to get one of these running on my stand and eventually in my sand car. Im at a standstill until I figure out how to get FIRE:)...any help would be awesome..thanks everyone! Mike

The EJ25 DOHC most likely overheated due to the infamous phase 1 gasket problem.

 

if you use the 2.2 heads, you should be able to bolt on a distributor to it. If you have the pass side head, take a look at the back and there should be a sort of round plate about the size of a 50 cent piece w/two tabs securing it to the head. This is where the disty would go. Then everything should be the same as what Monstaru did.

Thanks s'ko. Im in the process of rebuilding my aircooled 2332 but once I get the subi figured out it will be going into my rail:)...thanks for the input! Mike
