convert 3A to EFI

Pegger · Post by **Pegger** » Sat Jan 15, 2005 10:23 pm

I did think of that, mounting the injectors right onto the intake, as close as possible to the head. The problem there is the precision required. The holes / injectors would have to match the positions on the rails exactly. Do-able however... (I think)

Another nagging issue is, will that intake even fit "around" the exhaust manifold"? Even with my enthusiasm for this EFI conversion, I have my doubts...

I'll go out and take the measurments, then I'll know if I can do it this way or find something else...

P.S. That yard you talk about sounds pretty cool, I'd love to have one like that here.

Does anyone have photos of the top of either or both the 4A-FE's and 3A pistons?

I looked at that Russian catalogue and the drawings aren't convincing me that there is or isn't going to be valve / piston clearance issues.

I'm re-considering using the 4A-FE head.

Again I think I can pick up a donor car in the sub $200.

Guy

P.S. Not giving up on the other ideas, just checking out all the possibilities.

If you were going to mount the injectors into an intake manifold yourself, you could just stick with the head and intake that you have right now...then you wouldn't have any problems with header shapes etc etc or valve clearances...

You could also not worry about non-interference and just hope the timing belt doesn't break hee hee

I guess I didn't realise the injectors were on a rail...perhaps you can remove them from the rail and use hoses instead?

The deeper you get into this conversation, the better a whole engine swap sounds, to me anyway! heh

OK, I think what I will explore now is to mount the injectors on the intake manifold.

Perhaps weld a boss onto each leg and macine a hole at a decent angle to mount the injectors.

I'd like to do it on another intake manifold than mine... (keep the car in use)

Anyone have a 3A intake manifold they want to part with?

I sort of have an extra one. I'll check the condition of it.

Gasoline Fumes, are you the fella doing the Suzuki TBI conversion? I can't remember who was doing that...

If so can you give us an update...

Thanx, Guy

T.B. Please don't put a car out of commision for the sake of that manifold...

Yeah, my friend and I are doing the Zuk TBI conversion. An update? Does postponed until spring count?

It's about 20 degrees in my friend's shop and the wiring in there kind of died with a spectacular display of smoke and sparks. So it's a little dark too.

Don't worry, we have 3 manifolds. I said I sort of have one because it's not really mine, but I now have permission to send it off somewhere. I forgot to look at/for the manifold. I'll try to remember tomorrow.

Oh for sure, a Winter delay is permissable..!!

Ok, manifold... let me know how much you want and I'll try to guesstimate shipping...

Thanx, Guy

How about $15 US? I still haven't taken a look at it. I'll try to remember. :rolleyes:

I managed to find one here at a wrecker. They'll remove it for me as it's winter and miserable here...

Thanks, Guy

Now I can stop promising to go look for it.

I can't wait to see how your EFI conversion turns out. Hopefully there will be two 3A-E (or 3A-CE?) engines some day!

Pegger · Post by **Pegger** » Sun Jan 30, 2005 8:39 am

Yes, the 3A-E... Sounds good. I hope I'm not being too ambitious with this project...

I'd like hear some of your ideas on how to mount the injectors to the intake manifold.

I'd like to use the same fuel rail. The way it mounts actually holds the injectors in / in place... (the donor system is from a 3-EE engine, it has the same intake spacing as the 3A, same displacement and is cheap)

Maybe weld a boss onto the intake legs...

Share your thaughts...

I can't think of any other way of doing it. I'd just have some bosses made for the injectors and then weld them in.

What do you plan on using for a throttle body?

If you need any 3E-E measurements, my sister has a 1993 Tercel.

Pegger · Post by **Pegger** » Wed Feb 02, 2005 6:30 am

I'll probably adapt the throttle body from the 3e-e. I hope it's a decent match...

Maybe the T.B from a swift like you did might be a good option... I saw you put up a drawing / diagram with all the measurments for the adaptor plate...

Thanks for the offer of measurments... I have a 91 here (needs an engine) I'll be OK.
