Tthis is a sticky for those who have the 1ggte engine. We can do this several ways:

1) Just make this a gigantic ongoing thread, or

2) Post questions in the regular forums, and once they're answered, place links to them in here, and we'll keep it updated. It's up to you 1g guys. let me know either in here, or via PM, and we'll get this rolling. :)

Re: 1ggte(u) information

i'm new to this site. i just recently had a 91 1ggte put in my 89 ma70. a few problems already. one-no tach, two-can't find a down pipe or really i just need the flange, three-the car doesn't like to idle, four-this is more of a question than a problem for now but, i went to atmospheric dump (bov) do you think that might have some to do with the idle problem? the only place i have found that can find anything for this motor is www.toyospares.com they are in australia i sent them my wire loom and they got me some other needed parts very helpful. anyways if anyone has any ideas for me i open for any suggestions i only recently got in to the whole supra thing. i drive and 03 evo and that has been my main focus so i needless to say i am ignorant about the supra

Re: 1ggte(u) information

their is a goliath dp im not sure who makes it but its out there. as far as a bov these cars didn't come with them so no they dont like them but if you do use one then yes it will make the car idle weird and run really rich from my experience. you can get a bosch bov and it will run ok. why dont you have a tach? do you mean not in the gauge cluster or what exactly? have you checked your timing? yours is a 3rd gen so it should be running 10-11 psi stock. www.importbitz.com has a single turbo mani with a 40mm ext. wastegate for 550 and you can find other parts for them over in aussie. and japan. in japan they made a full stroker kit at one time you can search yahoo japan auctions they have them sometimes

Re: 1ggte(u) information

i will have to check the spelling on that site. thanks for the info. maybe i will sell the ssq HKS bov. and get an internal or half and half. i have a tach but maybe during the swap that wire didn't get hooked up or something but now that i have the diagram i can look for it and do it myself. do you know what size injectors are stock on the 91 1ggte i swwaped them with the 7mgte n/a that are 430cc i think so i hope i didn't screw myself.

Re: 1ggte(u) information

if im not mistaken they are 330cc stock i have a set of na injectors do they just swap right in? i know for a fact that 13bt injectors will work they have to be rewired but they are 550cc. how well does yours run with the 430cc inj.
also you should join www.supraforums.com.au they have quite a bit of knowledge on the 1g check it out.

Re: 1ggte(u) information

hmm good question i don't know it was the N/A so i hope i didn't down grade. it runs fine, right now i have to adjust my piping because i keep blowing boots off. but ya i dind't have to mod anything to put those injectors in, one of them is leaking right now because the o ring i think so i have to fix that next, it is still very much in the works i still have no down pipe (no exhaust at all right now) i need to find a down pipe or just the flange so that i can at least make my own. because it would be nice to get a exhaust on there and get it inspected.

Re: 1ggte(u) information

I was referring to maybe a list of required parts, and maybe some info on if you would need to modify stuff like you would have to on a 1JZ (motor mounts)

Re: 1ggte(u) information

i was comparing the 89 7m ecu vs the 1g and theres actually very little that is actually different, theres only a couple of wires different and of course there being 3 inj signal wires vs two on the 1g

the 1g's are the same as any a70
get same year mounts and engine harness... and plug her up and i think you're good to go :)

you may need to do some wiring at the ignitor coil side of things as thats slightly different to 7m but it shouldn't be too hard ;)

Re: 1ggte(u) information

OKay, I checked the 1g tach that came in my car but was not working. I got it to work today. It is exactly the same and nothing needed to be changed to work with my 1jz setup.
If you look at the 1jz gauge cluster wiring, it shows the 1g as well.

Re: 1ggte(u) information

I know that this does not relate to the manual, but I don't know anywhere else to go. How can I get a 1gg tach?

Re: 1ggte(u) information

I am looking for one also! I think what i will do is take a hi resolution scan of the TRD 10K rpm gauge and print up a new back plate then use it, and tune my standalone ecu to drive the tach so that it matches the RPMs with the display or ecu logging

Re: 1ggte(u) information

hey guys just in regards to the 7mgte 430cc injectors into the 1ggte, has anyone done this and do you need resistor pack for them to run properly?

Re: 1ggte(u) information

I was looking at information about weights of the 1JZ compared to the 1G-GTE on another site, but I'm not sure how legit they are.

Does this sound about right?

1JZ-GTE - 477 lbs
1G-GTE - 385 lbs

I'm also looking for information on the length of the 2 engines if anyone has this info!

Re: 1ggte(u) information

OK, here is the length as well... now this is coming from just sources on car forums so it may not be right:

1st gen 1JZ length + weight: 29.5" + 477 lbs
1G-GTE Length + Weight: 27" + 385 lbs

Re: 1ggte(u) information

Will the JZA70 disc rotor, anchor plate and caliper be a direct bolt on or do I need to fab some thing to make it fit?

Re: 1ggte(u) information

it's an a70, everything bolts up :)

ga70 got the big brakes in 1990 whereas the rest of the a70 jap imports got them in 89.
