Universal 3sge (inc Beams) into AE/KE thread

[Bozu]

And what about the loom? Do I only need the engine loom or do I need the body loom as well? I called a shop here in Perth and they said I need the complete wiring loom but I don't see why...

i wouldn't even bother contacting jay/buddyparts.

you will need to add a return to. pump doesnt need to be anything amazing. but it needs to be just alittle bit better than a stock 4age pump. im using standed 1/4'' lines also. you'll need a desent adj regulator.

the throttle has been covered in earlier posts, just manually control it.

Now the fuel rail is an interesting one, for the people who have done the conversion what have you done in regard to the returnless system? From what I hear it's too hard to get the original pump to work for some reason and it's better to just mod the original fuel rail to have a return line and regulator

This is for a conversion into an RA23 Celica, though it shouldn't differ for the AE86...


The fuel rail has a threaded bung at either end - I believe its a metric thread - can't remember the pitch - wasn't a problem though.

All I did was replace one of these bungs with a speedflow fitting - there was a -AN to Metric adaptor I used.

From the speedflow fitting I ran some hose to a SARD adjustable fuel reg.

Then from the fuel reg I just ran some more hose back to the factory fuel return hard line.



Super easy - no huge modifications just a matter of getting the right fittings.


As far as the fuel reg goes - don't hook it up to vacuum - just leave it as the Beams fuel pressure stays the same.

I believe 62psi is what you're after. Adjust the FRP until you hit that.



I used a Bosch 910 at the rear end with surge tank etc...

jay had alot of trouble trying to setup a returnless setup. cant remember exactally what they struggled with, but i think the fuel got really hot.

and isn't 62psi pressure for a returnless setup? with a return its drops down to about 40psi doesn't it?

[Anthony]

yeah I just put a std toyota banjo inlet form a ze rail in one end (M12 x 1.25 i think youre after), used that as a return and ran an external nismo regulator at 55psi. worked fine.

[Major Clod]

The returnless setup in the Altezza just means that the pressure regulator is in the fuel pump, rather than at the fuel rail.

With the factory ECU at the factory tune, it is expecting 62psi at the injectors. Returnless or not if you're lowering the fuel pressure on the factory tune, you won't be getting the right amount of fuel in there.



I had the factory altezza fuel pump with my halfcut - I hooked it up and ran the engine on the fuel pump - measured the fuel pressure at the rail.

I then hooked up my Bosch pump with SARD regulator and adjusted until I had the same pressure at the rail. Engine runs perfectly.

Numerous street km's and quarter mile runs later no issues here.

[Sam-Q]

so just get a reg and run it at 62psi? easy as, thanks guys

@ Anthony
I heard you can shed some more light on the starter motor issue?
What starter can I use on a beams+W57 combination? One from an AE101/AE111'? If so, could you tell me what has to be modified?

[assassin10000]

I think he modified the snout/mounting ears.
