Just how far can you go with a 2TG?

[JUSTIN K]

Hi All,

I am currently going through the process of deciding which engine to put in my 75 corolla coupe. Thing is it has a worked 2TG in it now and although it's getting tired now I have grow to love the sound it makes. So my question is ... just how hard can you make one go - n/a or turbo? I realize that the argument for turbo motors over n/a motor is run and won but I still love n/a motors.The car has to be everyday drivable..... but only just! I can put up with anything for a good motor ( I don't do stereos in cars!) :-)
The 2TG/ 3T hybrid sound like a good thing but is it appreciable better? I'm not shy of spendin a buck if it's goin to be worth it . Conversely if a 20v is just that much better let me know.
On a different topic I've heard that the toyota steering boxes can be quicken up - any one know about this.

Thanks guys
Justin K

go something new for an easier starter point.
you can mildly work something new, or go nuts on the old 2tg and lose all economy and drivability for in the end, the same result. with more usability from something new...
4agze, then turbo it after its up and reliable

I agree with u that it would be easier but the car already has a blue plate for the 2tg and I guess what I'm really asking is what's the most powerful na 2TG anyone has heard of. I'm thinking along the lines if the utimate 2TG. 3TC bottom end, forges, headwork throttle bodies - the lot. A 2 litre 2TG with the works would surly have to make at least 200 hp.
Anyone seen anything like that?

[rob1]

yeah. you're about right. apparantly 200hp is achievable.

[JUSTIN K]

COOLl! Thanks man. Is anyone on this site running a motor like that or is the lure of the 4a too strong these days?

[Screamn_Sleeka]

2T-G work: http://winterpalace.customer.netspace.net.au/ and click 2T-G modification.

Yes, the 4A lure is attractive. But i cant see any advantage of a 3S-GE, except cost, 4A will be much cheaper. (cheaper means 6k instead of 8k).

"I've heard that the toyota steering boxes can be quicken up" - what the hell is a quicken up?

[rob1]

do you mean tightened??
yes they can be adjusted. there is a locking nut and thread that can be adjusted to tighten the tolereance in the steering box. pretty easy to spot and work out.

[JUSTIN K]

Thanks for that. I meant that there are ways of modifing the steering box to reduce the number of turns lock to lock - apparently. can anyone confirm or otherwise

[Screamn_Sleeka]

No, unless you change the gears inside. Other wise you change the wheel hubs to something with longer steering mounts, like off a power steering car. But then the steering will be too hard.

If you are serious about TA22 steering, its center pull rack or bust.

car is actually a ke 35 but am sure it will prove to be the same. thanks again.

The 2TG is an excellent engine for its age. And i agree the sound of a worked one is awesome. If you check out this thread you will see what is possible. In my opinion a 3/2TG hybrid is hard to go past. I find it plenty quick in my 22 and it would be quicker again in the lighter corolla. A hybrid with cams exhaust and re-jigged carbs can be very quick and still easy to drive. My engine makes just a tad more than a stock 20v at the wheels but at 6500rpm instead of 8000rpm, which do you think would be easier to drive? Economy on a worked 2TG does suffer though

As for "quickening the steering" i stumbled on this thread the other day.

Going the 2TG, is a good way to kep some old school goodness. There is nothing wrong with going 4A, but I prefer using the 2TG in my TA22. Yes it will be easier and cheaper in the long run to get more power from the 4A or other newer engine, but sometime you just wanna hear that wonderful carby fueled twin cam.

I currently have a worked 2TG in my Celica, and it is putting down 91rwkw or about 120ish in HP at the wheels. This isn't a very nice street car and is best suited to a track as the power only comes on over 4500rpm. There are other on here that are running the hybrid 3/2TG and are safely getting 85-90rwkw, and their cars are very streetable.

Which ever way you choose to go good luck with the work and keep us posted of the build.

[schnitzel]

Old rally car used to get 252 bhp but that involved lots of work to 2tg and mega bucks for its time. Can be done but car is not really streetable. 200 hp and semi streetable is acheivable particularly if you go aftermarket efi and go out to a 2 litre configuration. i.e. 3t crank and rods forged 18rg pistons and a lot of cam and head work. depends how much you want to spend and what you want to achieve.

Care to share how you make 18R-G pistons fit into a 2/3T-G? Considering that the 18R-G pistons have a 5mm greater compression height. I think that there are some VW pistons that can be made to work BUT I haven't done it. I'd rather buy something made for the job.

252 was the answer I was lookin for! I realize that the engine you are quoting would be a works built hand grenade but they never had the benefits of efi and cryogenics - we do! I keep hearing how it's cheaper to go turbo but that hardware still costs! factor in conversion costs ect and that leave a pretty serious budget to play with.
I really wanted to put a 1uzfe in but the leavel of work required is huge and time consuming.great if you have the time but i'd rather be driving. the other thing is that if the engine is fully built it won't be scared of nos either! :-)
