Getting 15's from a 2TG...ideas?
|
Tue, 22 June 2004 11:17
|
 |
For arguments sake, and I know there are a heap of variables, just say that I am aiming to get a 15 second run from a stock 2TG..
What mods would you do to get close to a 15 second run?
Just assume it's a stock as a rock 2TG in a TA22 running standard everything..
Ideas?

well,
id start with an headers and a good exaust.not to hard to come buy,and you can always use it again,or most of it for another engine.
air filter is another easy one aswell.
assuming you have carbs(you said 2tg),take a closer look at them.maybe upgrade them.(dont know much about carbs,i have a 2tgeu).
if you wanted to go a bit further on teh engine,match porting and also teh addition of a 3t crank.bringing it from a 1600 to an 1800.
im not sure exactly how quick these will make you,ive never done teh 1/4 mile in my car(77 TA28 2T-GEU),but they would help nake you car a bit quicker.
cheers,
Dom

has anyone done the 1/4 in a stock 2tg/2tgeu powered ta22 (or T-18 for that matter)
Just wondering how quick i could expect with a stock 2tg powered T-18 (similar weight to ta22) with a megaquirt efi conversion
Not that im building it to drag race

I am fairly sure my car can do a 15 easy. Well, using a G-Tech I got 15.95 sec. I only tryed 2 runs and had a passanger, full tank, spare etc. Without the spare tyre or passanger, only 1/4 tank fuel, some small adjustments, I think 15.5sec would be very easy.
I have a KE55 corolla, maybe lighter than a TA22 but very similar. I have leaf springs with tramp issues still.
Engine:
2T-G with 3T bottom end, 3T-C pistons = 1812cc
stock flywheel lightened to about 6.5kg
305 degree camshafts
40mm solex carbs. 32mm venturi
plus aux venturi as standard
145 main, 150 air, 57.5 slow
this is running lean, still not jetted right.
Only revs to 7800 for some reason
2" exhaust
195/60/14 Potenza RE711
The secret here is:
1. light flywheel
2. 305 cams (can go wilder)
3. 3T bottom end
If I need more I will get 89mm forged pistons, and 45mm carbs with large venturi and jetted to suit. And for the track, 320 cams could be used. 305 feels very mild with my setup. People have go into the 14's fairly easily. Into the 13s would probably require nitros or turbo, not sure.

With a standard 2T-G, you can expect a time of about 17.5 seconds. Thats what mine did, and its what a new TE37 Levin did. Give it a light flywheel and you can probably take off a second. To get cheap easy performace, don't even bother with a port and pollish. Get a light flywheel, the hottest cams you can find, and make sure everything else is in good standard condition and the carb jets are right.

The 3T crank and pistons give a longer stroke = bigger capasity.
2T = 70mm stroke = 1.6L
3T = 78mm stroke = 1.8L

3T crank is 78mm stroke, 2T crank is 70mm stroke. 85/70=1588CC, 85/78=1770CC, 89x78=1940CC.
I think for 15's in TA22 you'll need to either
(1) take it apart and...
3T crank
89mm bore with forged pistons at ~10+:1
long duration camshafts
jet Solex carburettors to suit
or (2) get a 2T-GEU with factory ~8.x:1 and bolt on...
turbocharger manifold
turbocharger
aftermarket injection control
intercooler
If you go for (2) you'd want to get a good condition motor to start with, or else you'd have to pull it all down anyway for rings, bearings, hone, etc..

Nickel,
My old TA22 with stocker 2TGEU ran a 17.6 from memory, either that or a 17.8 ?? It was mid to high 17 second pass anyway.
Tina's TA22 with modded 2TG ran a best of 16 flat. That was with the 3T crank, mild rally cams, 1 mm overbore (1812cc) and 9.8:1 compression. Base timing was set at 13 degrees and the Dizzy was regraphed to suit. It turned 60kw at the tyres from memory with that package.
The second round of engine work never made it down the quarter, it turned 76kw on the rollers but its only attempted pass down the dyno saw it lunch the rear axels, diff centre and rear uni joint. ! Damn sticky tires lol

Would boring out a 2TG block have the same results?
Thanks guys for your input...it's been very helpful!

Or instead of all that engine stuffing around, you could somehow ditch 150kgs of weight...
Good luck with that though

my 3tgte runs 15.6 in ta22 it has been dynoed at 100rwkw. so im thinking ull need at least 80rwkw to get a high 15 pass. my car has a borgwarner lsd and very stiff suspension, also i didnt drop tyre pressure when dragging. my car drifts very well but isnt setup for draggin if it was id probally run low 14s.

we'll i know it is of track a little but i managed a 16.1 at 85mph with major traction issues off the line (Single spinner, half average tyres, stiff springs and Just over a 6 grand launch The car could have got into the 15 second brakcet if i hadn't launched it at so many revs but it was fun
This was in a Ta22 with a 2T not 2tg it had a fairly tame cam (only could tell by the sound) Twin 40mm webbers, 89mm bore with what i was told were forgies, standard head and valves etc, billet flywheel (extremely light) and other than that the motor was fairly standard. Ah forgot to mention Drove it from hobart to launy which is about half the state(canning it of course) with a blown head gasket and then did the drags and then drove it home (motor is now deceased)
So i thought 16.1 one wasn't bad for a motor that is on it's way out

That's a mighty fine effort with a 2T! You'd have one of the quickest ones going around! hehe
...I should say did!

It's not really 2T related, but you may find some helpfull hints here
The process definitly worked for them, although I don't know if I would take this approach on a celica.

Hi,

Only revs to 7800 for some reason
|
It runs slower 'cos you have increased it's stroke. If the increase was from boring, you'd keep your rev range, but with stroking you lose some revs.
To check this out and other usefule 2TG and other Toyota engines and diffs and stuff, go to http://www.toysport.com, and go to the "Tech Info" tab and you'll see the different stuff there.

How about a different but still cheap option
Get hold of the 2TG EFI manifold (Around $200 bucks)
A Megasquirt DIY EFI System (Around $250)
A 4AGZE Supercharger (Around $250)
A bit of Welding and swaering
Hey Presto
Tim Frost did this albiet without the megasquirt
http://members.fortunecity.com/daytona/technical/2 t-gze.html
He went from 71RWHP to 130WRHP
Thats almost double the HP at the wheels, should easily achieve your goal for around $700 in parts
