Celica 2T / 2-TG / 2-TGEU / and 3T series engine specs *sticky*

Hi,

210HP from a naturally aspirated 2T with bugger all mods...

River why did you bother to turbocharge an 18rg again??? Flaming old buckets of crap - can't believe you still persist with em...

If it wasn't for the fact that an 18R-G craps all over a 2T engine, with all things being equal, I'd gladly have a 2T.

Really forgot about this !

Racing our 2-T side draught crab pot motor at QR, the tacho went waaaay past 8000 RPM

Now.. Dont know how accurate a 35ish yo tacho is (must check that) but a well built 2-T
does perform quite well for its 1.6L goodness

Hi,

Of course it performs well. The 2T engine is a superb unit.

But, the 2T-G is way better again.

an 18R-G craps all over a 2T engine

How so??

For a 2T with absolutely nothing more than a 40thou head shave, heavy duty valve springs, reground cam, and twin carb upgrade to produce over 200hp is amazing.

To shift a full weight TA22 over the quarter in 13.9 seconds takes 210 horsepower to the track. Thats going to come out at around 180RWHP - maybe even more depending on the dyno.

Given this HP figure is well above most - if not all - heavily worked 2TG's, waaaay out of the league of the crappy 3TC, and you'd have to have at least upgraded the smelly old standard turbo on a 3TGTE to match it, then how much more proof of the 2T's prowess would you need River?

Just imagine if some brave - if not a little foolhardy - soul dared to turbo a 2T?!

Cheers,

Have to politely disagree there River

Have had a 74 2T-G, 75 2T-G, 75 2-TGEU as well as Dads 2T/3T GEU hybrid

The snot box 2T in the race car actually revs way faster n more easily than the others !!

Made us go wtf???

Torque is a bit lower but the damn thing grabbed dirt and (made me ) spin out changing from 2nd to 3rd at 45 mph on the staight at QR IWMAC dirt course

2 thumbs up for the crab pot motor !

[Scoobzd]

Oh and another DIY job is to port both the inlet and exhaust manifolds to create a vortex ><

Dont do a straight through matched port == but have a >< port

http://en.wikipedia.org/wiki/Vortex

A sand blasted like finish (factory) is required on the inlet (DO NOT MIRROR POLISH) but if you want to go nuts on the exhaust, go for it !

Doing a mirror finish on the inlet creates adhesion as the fuel (vapor) goes through

Matching the manifolds to the head and doweling them in place is recommended

That power would only come in around 5k+ rpm. It would not be a street friendly engine. To pull that power out of an NA 2T would be for race/drag purposes.

A similarly modifed 2T-G would outperform the 2T.

The 3T-GTE was built for reliable, daily street use.

It is pointless to compare a race-built 2T engine against stock engines such as the 3T-GTE and "worked" 2T-G street engines. The reason you see turbo'd 2T-G engines about (and not turbo'd 2T engines) is the 2T-G is a higher performance engine to begin with.

As I said before, the 2T is a wonderful engine and easily lends itself to be modded for some good power. The 2T-G however, is better again.

If your 2T revs better and has better performance than your 2T-G, then I suggest you need to re-tune or rebuild/fix-up your 2T-G engine. Having owned a 2T and 2T-G powered TA22, I can assure you the 2T-G engine is more powerful and revvy than the 2T.

Maybe Toyota Racing got it wrong all those years ago and should of raced its LT 2T powered Celicas instead of the GT 2T-G powered models?

Ahhhhhhhhhhhhhh My head hurts.

There was another one of these style 2TG threads around with buckets of copied and pasted info and misinformation in it it has some much BS in it I just couldn't bringmyself to edit it.

Can we try and have just 1 thread with worthy content please. By all means make this a T series mods and upgrades thread if thats your intention.The tech info and specifications stuff is well established so as suggested add to OMR's thread if you have accurate info to add.

There are few forum related things I hate more than misinformation. And while in the land of the blind the one eye'd man is king, here on Toymods with have many with 2 eyes.

I dont have time here at work to wade through everything but if you clowns want to post up tech info, Take the time to make it accurate and factual.

I'll argue about your 2T v 2TG rubbish later.

Gearbox X members: People chase the TA22 Auto one for W series conversions because the RA23/28 ones dont fit under a TA22. You dont think the 76-77 model x members being half the width makes a difference ?

Short version because I am at work.

Yes a N/A 2T with high compression, a Big fuck off race cam and valvetrain and fueling to suit can make the 180 odd HP end of town. No arguement at all, I know a dude that had one and they are perfect for your adverage redneck racer as those twin cam things get too confusing.

A 2TG with the same mods will make around 220HP, I also know a dude that built some

The limitation on your 2T's are valvetrain related, putting asside the basic physics of valve sizes (2TG's having larger valves that 2T's) Why do you think performance engines have shim under bucket, instead of pushrods. Mechanically speaking they are more reliable with less to fail. Twin cams also brings the joy of adjustable cam timing among other things. BUT yes if your happy with the less reliable option you can make a almost as much power, spending aboout the same money with a 2T... For a while.


As for a Turbo 2T - Last I spoke to Yogi the fastest time his TA22 has ever done down the quarter was still with a Suck thru turbo charged 2T, 13.1. The 20V 4AGE Turbo, mini tubbed rear end and Powerglide had yet to get their

Wasn't trying to upset anyone out there guys

A lot of young guys just want to get there 2-Ts going well and I thought any info is good info

Again, was just trying to be a help & not a hindrance... sorry

[CheeseBiscuits]

Being internet and all its hard to tell...

but I thought NME308's post was sarcasm...

[TheToyman75]

Gordon,

A thread with good solid info on what can be done to a 2T has merit. It just needs to be good info.

Saying you had a 2T powered TA22 that ran 13.9 is a good insight into what can be acheived and gets people interested.

If you can follow that up with cam specs, compression ratio's, valve spring rates and maybe what else was done to the car etc, then its better again as the young n keen can copy the theme and do it themselves. The can also evaluate it in real terms.

I am all for Good info. Rodger on here for example has a Single cam Celica most on here would trade both testies for.

Useful hints and tips related to 2T's and 2TG's etc is a good basis for a thread, just try be accurate and where possible provide as much supporting info as you can. Th biggest problem with info is second hand info that is regularly wrong or partial info that leaves all key information.

I'll trim out the tech n specs stuff tonight if I get the chance and change the heading for you if you like ? That way its on direction and you can continue as intended.

[toyboyracer]

Cheers for that.

Feel free to use your God like Mod powers to alter anything I get wrong in here

Sincerely meant this to be a tech thread to try and help out the young fellas with
info/specs/what to do/ideas and the like.

With luck one day in 200 years time when hydrogen cars are the norm, people will be sooooo jealous of what we guys are currently doing.

BTW, my old HR X2 Premier 192ci ran 13.8secs @ 98mph on the now defunct Surfers Strip

and the 2-T 13.9 was a typo on my part (doh...) was 14.9 but still not bad

[Hurricane]

mmm this thread seem to be fallin apart quick, what about if we can clean it up and just post tech info, etc?
and then correct were needed.

not trying to tell any one what to do, just seems the threas is getting a little of track?

ill replace this post with some tech info later on.

Hi,

Agreed.

The original 2T Engine tech thread is here....
http://www.toymods.org.au/forums/showthread.php?t=1139

As suggested, it would be best to add to this existing thread, rather than create a second thread for the same engine series.

There is a 3T-GTE tech thread already for info on this engine.....
http://www.toymods.org.au/forums/showthread.php?t=31201

However, I don't beleive there is a thread for the 3T (non-turbo) variant. If one has good tech info then start one!

As such, I'm closing this thread.
