2t geu t-18 conversion

hey guys, im bak askin questions. ive finally started taking the 3tc out. anyway i was lookin at the part numbers for the 2t-geu i have and the numbers are all over the place so im just seeing wat u guys think of the parts which it has been assembled from. the head is 11111-88260 (no egr system on engine!!, is that just part of efi or head?), block is 11411-28010  its the last block used on the 2t-geu was used also for 3t-c (its got 2t on the serial number), efi is 17111-88262 so its the last version gex2 system (EFI on it), gex2 computer, and computer wiring harness. Plus i have genie 4-1 extractors for the engine.
i have no idea about the internal setup though  , but it was only just rebuilt and it was by someone who is part of the drag racing fraturity. fingers crosed he put high compresion pistons with 3t crank, but they are wishes. Standard injectors but thinking of buying 3t-gte ones. so guys plz tell me wat u think and any1 who has put a 2t-geu in a t-18 plz give me any information concering the wiring.
thanks blake

hey im having trouble with the wiring loom for the efi computer, plus from a post by thetoyman it seems i might be missing parts to run the standard computer. i have the afm (wondering if i can replace it with 1 with less restriction), computer, efi wiring loom, efi unit. i was just wondering if some1 can tell me all the wires and components involved in the stardard factory setup and if any1 has a full wiring diagram cause all the 1s i have seen havnt really helped, i had to use 1 of a 3t-gte but want to make sure.
thanks

The oxygen sensor is normally situated just after the collector on the exhaust manifold. The engine will run fine with no oxygen sensor, but fuel economy will suffer. You cannot remove the airflow meter without upgrading the entire engine management system. As for wiring, this diagram should be all you need:

thanks for that norbie, yeah i dont have the sensor and i have extractors on the car, is there anywhere i can put 1 or should i not bother with it. with the afm i have the standard 1 but im sure i read somewhere that a later model celica had an afm which had less restriction (larger) that would plug straight in, i was wondering if that was true.

i've just installed an oxy sensor in my car, i've got 4-1 extractors, they had to weld a special plate just after the join in the extractors. they took an hour and $80 from me, this was for a 3tgte computer. I've run the 2TGEU computer for months without an oxy sensor, i don't think they are needed on such a basic EFI system, especially a 2TG.
There is a larger AFM out there (21RE or 18RGEU or something) which will be a straight swap for the one you got, but just think its bigger because its off a bigger engine, hence it will be tuned very differently. nothing worse than a factory EFI engine out of tune. also the throttle body is about the same diameter as the AFM, hence you would have to upgrade that aswell otherwise you would be wasting your time.
Goodluck.

plz if any1 has put a 2t-geu in a t-18 i need sum info on how u wired it. ive looked at the wiring diagram and the wiring loom i have and sum wires just seem to do nothing at all. also on the diagram it says "cold start injector control in head" i cant find it plus the distributer has two wires coming out of it whereas the previous 1 on the 3t-c only has 1, how do u wire this?

Well the dizzy one is easy - the 3TC has got points, whereas the 2TG uses electronic ignition - if theres an ignitor in there, then one wire goes to the coil - and the other to power, otherwise they both go to an external ignitor (most likely!) If you've got a multimeter, measure the resistance between the wires - if its somewhere in the range of 150-900 ohms (or there abouts!), then you'll need an external ignitor suitable for reluctor ignition.

looks like ill have 2 get an external igniter, im bit worried cause my efi looks different to the 1 which thetoyman posted on another thread, plus the wiring is not working out, there are too many plugs which have wires coupled together which by the diagrams dont go to the same thing

don't worry about the differences, there are many wires on the computer which you won't need. If you hook-up the basic wires it will all work fine.
All the wires you really need is-
-4 plugs to the injectors (#10,#20, power)
-TPS plug (PSW,TL,IDL)
-Thermo sensor(must use the green plug-NOT the brown one, this is for the cold start) (THW, EARTH)
-coil +ive, coil -ive and battery +ive.
The Oxy sensor, speed sensor, cold start injector and fuel control relay/circuit open relay are not required so long as your fuel pump +ive is run off your ignition. Once you get the engine running i would recommend wiring the fuel pump relay to prevent an explosion if an accident occured.
Go to your local toyota wreckers and pickup a working 21R-E coil and ignitor pack (you need an electronic ignition coil), this will have a red and white wire off the ignitor pack that will couple up to the two wires off your distributer.
The cold start injector control is the switch attached to your thermo-housing(the brown one). This switches the cold start injector on or off depending on coolant temperature, and gets power off the starter motor solinoid wire and is wired to the injector on your inlet manifold.
Also make sure you run your tacho off the negative of your coil, as opposed to the points distributer which gets the signal off the positive.

thanks for the help inferno, now ive got it sorted. gonna look around for the coil and igniter pack 2morow, wanna c if this engine will work or not. wat sort of efi pump would u reconmend to put in the car.
one more thing, the speed sensor? im guessing this is something u need, well it seems there is no wire for it at the plug at the computer but im pretty sure the connecter is there, where does this connect?

speed sensor- don't connect this up, it is not needed. The computer gets its rpm speed (and hence fuel demand) from the negative coil, theres no need for it to know how fast the car is going. I think it usually connects to the gearbox.
EFI fuel pump- i've got a VL turbo pump which i bought brand new for little over $300, but for a 1.6L all you really need is a cheap second hand one from the wreckers, you have to be absolutely certain its a high pressure high volume fuel pump- check that the car you pulled it out of has EFI.
the main thing is to get the engine running with the basics, don't tape the loom up until you know its all wired correct. EFI can be a bastard when it doesn't want to work.

yeah ive wired the engine in the car as per the diagrams and info which people have given me, but when i was turning it over so i could check the compression of the cylinders, starter motor worked fine, let it turn over a few more times to get the reading, then one of the wires from the voltage regulator starts smoking. hmm do u guys have any idea what could have caused this to happen?

firstly take out the computer, you don't wanna damage this. then take out the ECU wiring. think what wiring you have changed since you ripped the 3T out. its just a matter of elimination, you've got a power wire earthed somewhere. If its the voltage regulator thats the problem then it shouldn't be related to the ECU wiring.
keep looking for the coil, there are plenty out there, they should be out of later model celicas (like RA60's).

rob i believe you mean a 22re ignitor and coil !! there is no 21re !
i have a spare coil here but no ignitor, it isnt the stock one it was replaced with a firepower type coil, but then i went to MSD

ok well looking at my wiring diagram thats the white wire from the battery to the voltage regulator, which also connects to the 'B' connection on the alternator and the ignition switch. If you have a multimeter disconnect the battery and test the connectivity between this white wire and earth. If there is no/little resistance, disconnect the voltage regulator and try again, then if there is still no resistance disconnect the alternator plug to test where its earthing. It sounds like that 'B' connection on your alternator or the alternator itself is earthing, try disconnecting the alternator plug and cranking it over again if you don't have a multimeter. If you've hacked into the white wire to the ignition switch then maybe this is earthing at the connection or the computer(which should already be disconnected)?
Goodluck.

finally got the wiring fixed, checked all the wires and there was hardly any resistance between the +B wire (i think its that wire cant remember) to the alternator, checked every single ground wire in the bay, and 1 wasnt gettin a good contact, fixed that now its purfect. injectors are getting serviced 2morow, and should be getting a pump as well. once i get those back ill put the efi together. ive got the water temp, cold start controller connected up as with the coil and igniter (havnt connected the tacho as of yet), so once i have the efi and pump in the car should i just connect up the ecu and try to start her or should i do sum testing, if so could some1 tell me wat i should do

ok this electronic ignition is really pissing me off, ive already had the coil and igniter checked and says that they are fine. time to see wat u guys think wat these wires are for cause i have no idea. there are 5 wires from the cars wiring, 2 red wires which connect to the + of the coil origninally (one is connected to the battery, the other goes to a capacitor then to earth), 2 black wires to the - (no idea what these are for) and the tacho wire.
there are 2 connectors commin off the igniter itself, 1 connects to the dizzy and the other has been marked as the tacho wire its a yellow wire (i believe i connect the tacho to this wire right), but there is also a wire commin off the + of the coil and it has a connector on it(i have no idea wat this is for). guys i really need sum help with this, thnks in advance

ditch the tacho wire for now until you get it going (could possibly be shorting etc), there should be some wires which go from the ignitor to your negative of the coil, these earth the coil and make it fire.

this yellow wire could be the one to the negative, maybe it was connected to the connection which had the tacho connected to (-ive of the coil), so you couldn't just connect this straight to the tacho but to the -ive aswel.
Don't worry about the left over connections, if your using a different coil and ignitor to your car loom chances are the connectors won't connect up.
goodluck mate, hope this helps.

ok to fully clarify myself, there is already 2 wires which connect to the - and + of the coil, i tried ur idea of wiring the yellow(suposed tacho wire) i got 1 spark and then it wouldnt happen again, hopefully i did blow it, last thing i need is to find another 1

having a look at a wiring diagram i have on a '90 cressida theres a connection from the ignitor which connects to the tacho, this definately connects to the -ive of the coil, but the wire is black and yellow. the black and red does have power from ignition and a noise filter to earth. theres another black and yellow to the computer(probably specific to the engine this diagram is on), and a yellow and green wire which seems to go to the computer(?) aswell.
so check everything again, i'm quite sure the tacho is a pulsing line from the negative which comes from the ignitor/dizzy.
there should really only be tacho and ignitor conected to negative. some people connect things like fuel pumps etc to positive so they get a constant power supply, do you have any of these connections?
i'm only going on my experience, just trying to throw suggestions to help you out here dude.

ok just went to the garage and grabed it.
i've got 5 wires out of the ignitor. i've got a pink and white, these go to the distributer, next a baige to the positive, then a white which has a single pin connector which i left not connected to anything (possibly to computer???), and the end wire is black, which goes to the -ive. i had my tacho wire(thin black) connected to -ive, and to my +ive had a noise filter, power from ignition switch. i also had one connection to each from the computer when i had that wired up(21RE computer).
my coil has a grey end, part number i think 19070-35040 [101311-2762-12V].

finally found out wat the problem was, the igniter wasnt switching because the pluse from the distributer wasnt a large enough voltage. got another 1 off a vc holden, i am told by the efi guy who checked the igniter and distributer that it will work, so hopefully it better, no i just need to get a vn fuel pump

ok, wat are the specs of the standard injectors on the 2t-geu, i know that they are 220cc/min but wats the resistance, and could sum one tell me the test conditions when they got 220cc/min reading cause i got my suposed "standard" injectors cleaned/tested and i got sum very weird reading from the place.
heres wat i got bak from the place, injectors tested at 2400 rpm with pulse rate of 6 milliseconds and 40 psi. the flow after being cleaned and that was 78ml/100sec, that seems WAY too low, am i right

ok, i've got a spare bottom half of a 2TGEU thermo housing, not really willing to give it away but if you definately need one and can't find one from then i'll post it over.
if you need one of the magnetic pickups for you dizzy i have a spare(two spare) you can have for free.
they are supposed to be around 2.7ohm. just check them with a multimeter. i think your injectors are pumping around 50(?cal)cc/min, which is low, but they probably didn't test them at full duty cyle/full flow. i think the 220cc/min is the rating with the injectors open fully, i don't know, but if they are cleaned and look like 2TGEU injectors chances are they won't let you down.
most high pressure fuel pumps will do the job, you should really get a surge tank eventually. i wouldn't bother with a new expensive pump, unless your going to need all the fuel you can get for a turbs

great to hear!! just shows if you hang in there you will finally get it back on the road. The EFI is very basic, but once you got your head around it all you can start thinking about whats involved in adapting a supercharger to it
pics would be great .
