2tg/3t hybrid

[Rodger]

I'll look up the specs. Or have a look through River's T series thread as it may well be that the flywheel is machined from factory to suit both sizes.

Looking at that light flywheel of yours I can see the clutch plate was not fully reaching the outer diameter of the contact face machined on the flywheel and this is the difference in sizes I am refering to. My Exedy H/D clutch is the bigger of the two but as Chuck points out is not the 3T-GTE bigger one. It starts to make sense when looking at the listing for clutch kits.

Ok, so the project has been a very long hard expensive road. But finally hopefully for a long time I won't have to touch this engine however I doubt it . So after it's terrible break down and removal out of my car I started the task of pulling it apart and replacing damaged goods.
While this process was ticking over I borrowed a 13T and had that in to get around. Problem was it was clapped and couldn't go over 4 grand, at least i never got a speeding fine ha ha.

As explained in more detail in my other post pistons 1 and 3 shat themselves and after it sat for a while the block and crank needed to be touched up too. During the process I got a little excited and went a little further then the original plans. I decided to buy some high tensile valve springs. After a tension test we found the purchased items were infact only the outer spring for a dual spring system. Deciding I already had half why not finish the set. So I had dual valve springs and matching seats installed.

Focusing back on my original project I had the block honed and new pistons, rings and bearings purchased and had to shave the head due to a portion of piston 1 being pressed into it. However I was still excited and went a little further. I found a pair of 222 cams and had them installed over my previous 220's. After the head work was complete it was packaged nicely and come home. I completed my part hoard by getting my hands on the last set of extractors to be produced by pacemaker for the 2TG finished with a beautiful blue heat proof paint. Then due to financial issues the process halted as alot of projects do. Luckily this one was eventually continued and after obtaining a few more necessary items the build began. I completed the build and put in half in today. I left a few gaskets at the workshop and need to pick them up tomorrow but I'm looking forward to the fun I'm going to have when this 2 and 1/2 year stage of my project is complete. As a word of advice to any wanting to do a project on ANY car. Do not try and do up your daily driver this is why the process has taken me two and a half years !!!! Well pics will follow when it's complete.

Hey mate, nice work so far and good luck getting it finished.

a few quick Qs

Cheers,
Chris

Ok so I finally got this little puppy tuned. unfortunately I need a few more things to make it sing. Like a bigger fuel pump. My fuel reservoirs are run dry at 5 1/2 RPM. Not good, definetly not good. however a brief update is it's producing over 100HP at this point so I'm pretty happy so far. Im really surprised this one didn't go bang too actually. In my lack of tuning experience timing was the first to suffer. Upon inspection my timing was set to 45degrees advance so not right! we turned it all the way back to 0 degrees and it's still going. To keep it safe though with my fuel issue we have turned it back to 25 degrees and I'm not to take it over 5RPM till i get this issue sorted so thats the update.

[Rodger]

Born,

Good to read that it has survived at least its first run.

Is that 45 of total advance and 25 degrees of total advance?

Normally a 2T-G is 10-13 degrees static and a total advance around 32-36.

An electric fuel pump with more capacity but not pressure (4psi max) and may also need a bigger (than 1.5mm) inlet needle and seat set in each carb, can get 1.8 and 2.0mm.

Look at replacing the hard small diameter steel fuel pipes with #6 sized hose if not already done so.

thats correct 25 total and 45 total. I just bought an electric pump so we'll see how that goes but I'm not too sure about the whole seat sets. the inlet needles are bigger then standard tho I think the mech pump is poo'd anyway tho.

hey,
I have a project car, 74 celica ta22 and the car has just been painted. Now its time to get my engine sorted. I have a 2tg head and 3t block. I don't feel confident putting it together myself. Can anyone recommend an engine reconditioner in brisbane who will do a good job for the right price?
cheers

[sillycar chick]

Celica74, Not sure who to recommend in Brissy for your engine build. Ive had small bits done by Engine Engineering in Rocklea but not a whole engine, they are pretty good and a good price. For the head I would highly recommend Peter Liddy at Sumner Park.

I just built my engine myself. Have you worked on engines before? Like reconditioning them? Its not too difficult if you have some nouse and an idea about engines, and do plenty of research on here!

Sorry I cant be of more help

[celica74]

hey sillycar chick. Havent had alot of experience reconditioning engines. I need to get my pistons shaved because they are aftermarket and my valves hardly open, the block I bought had already had some work done to it. I may end putting it together myself.. will see what the quotes are like.
Thanks for your help!

there's nothing like the feeling you get from building your own working engine. unfortunately there's also nothing like the feeling of when it goes wrong too. If you do decide to build it yourself make sure you check everything twice and don't take shortcuts! oh sorry mate but i don't know anyone in brisbane that could help you out.

[Born-Enthusiast]

Well I had a little bit of fun with this engine till the police decided to be mean and yes I'm bitter! my car got defected while I wasn't even driving it. all stupid shit too like to much play in the steering system when its a standard system and well working. Oil in my engine bay, brake pedal goes down to far.(I didn't have time to do a proper brake bleed when i fixed them two days ago) and handbrake not working when he failed to push my vehicle with it applied WTF! oh doesn't help when he has this attitude I quote " I hate seeing these pieces of shit on the road" he also tried to claim that toyota never released twin side draught carbies. oh and my idle screw was an aftermarket modification. Also that the stock air intake cover was again "an aftermarket performance part". so after prooving him wrong on a few things he sent my car to regency. Bye bye my loyal fair celica. RIP number plate WHY 764

[Born-Enthusiast]

sorry double post

[Born-Enthusiast]

just thought i'd put up a few of the photos I had taken of the engine in the car before I take it out and put it under a shed for however long

Good job on the rebuild, but on a serious note whats the purpose of rebuilding a motor if you don't have a reliable shell to put it in ?.

No offense but I suggest you pull your finger out and get your Celica road worthy so you can enjoy your rebuilt motor.

That aside, how does your 4-1's go? how much of a difference does the 78mm stroke crank have in performance compared to the 70mm crank? did you have to re-jet the solexe's? does the standard intake make much of a difference in accelerator response?
