Outer Limits 4x4 Board

I have been toying with the idea of fitting 1.3L import sierra TBI setup to my 1 litre, then fitting a small supercharger. The ECU should be able to handle the fuel, as its off a larger motor.

I have to rebuild my old 1 litre anyway, so I thought I may aswell get a few extra ponies while I'm at it.

And Pro's or cons that you can all think of would be appreciated.

Lots of sensors needed. ECU is likely to control the ignition, requiring crank-angle and cam-angle sensors, a detonation sensor on the block, etc.

Take the import engine complete and put it in.

its Throttle body injection ( single piont). All of the sensors and wiring required to make the EFI work are present.

this conversion was done by Mud4b on his 1.3L. I want to do the same to a 1 litre.

I keep dreaming of doing the same.
My line of thought go's;
Use Weber type throttle body, can be bought as single, double even triples.
This gives you a range of spares and injectors.Plus may bolt straight up with diagonal bolt Patton.
Saw in just bikes mag, blowers for Harley's, which are 1200cc or there abouts so should suit nicely. Seamed cheap. but would need further looking into.
Still thinking about Pooter.
Oh, and converting 4speed to 5speed.

The supercarger of the 4a-gze would probably be a good unit to look at for the forced incuction. And with the clutch style pulley, you could also rig up a mad max style switch to turn it on and off
From memory subaru also had a small (660cm) motor fitted to a really small shopping trolley overseas. This might also bit worth a look.
Layto....

just fitted 1.6 tbi to a 1.3 with an arm300 off a subuaru vivio or rex11. idles at 5 psi peaks at around 15. I am in need of a blow off valve though.

about how much has this cost u to set up? are u willing to do me and article thing for the bible?
thatd be great

thanks matt

two things wrong so far with this thread.
1. The SC12 off a 4AGZE DO NOT like mad max style switches to engage/disengage. It wears the clutch drive out very quickly and it expensive to replace parts. I used to play around with corollas and 4a's, and still do.

2. As you would know, Superchargers are belt driven, not driven by exhaust gases as turbo's are, and blow-off valves cant be fitted. The toyota s/c use a air bypass valve (ABV) but doesnt sound anything like a BOV, and serves to keep boost at a set level.

Another thing wrong with this thread, a supercharger pressurises air in the inlet system. When the throttle snaps closed a pressure spike happens in the inlet tract, so a blow off valve can be used. BUT it doesn't use the exhaust system so a WASTEGATE is useless.
