Just how far can you go with a 2TG?

[GeneSPIDA]

I wouldn't know which would work-out cheaper, going all-out on squeezing every last NA horsepower out of a 2TG or turbo-ing it, but I'd say in terms of streetable driving, the turbo option does lend itself to being driveable if you're not stupid with your foot, and power when you want to.

My turbo 2TG handles everyday driving fine, and knows how to go when I want it to. Approx 165HP at the wheels at the moment, although it has been higher (192HP).

Wasn't cheap/easy to get to this point though.

And a 3TGTEU might be the better starting point if you were starting from scratch. But then again, the 2TG/3TG hybrid is a great option too if you can put it all together. 3TG bottom end and 2TG head (apparently better), and replace the standard turbo with a better one (unless you don't want to muck around with the ECU).

Anyway, NA engines have lots of advantages, but to make them produce the kind of horsepower you're hoping for, sounds like low-end driveability will suffer.

thanks for that. yeah didn't think it would be cheap but it never is! Turbo holds appeal for all the reasons you mentioned but a screamin na gets me goin. have recently been in an n/a 2 litre alfa with sheets fa 162hp @ the wheels at 8700 with throttle bodies (and EVERYTHING else). If you think Toyotas are expensive try workin an alfa! What was stunning was that it behaved well on the road. didn't have alot of low end torque but did compared to a stock version!

First rule: steer clear of ANYTHING Alfa!

Next thing: Decide what you'd like. You could spend a fair bit on a 2T and end up with same sort of power as a stock Altezza 3SGE (200ish HP), so decide if you'd rather have the fun of doing a conversion, or have the fun of putting an engine together. Of course, the best option would be to work the 3S, but that's all a matter of how much you can afford! (I'm sure Glen will say plenty if he spots this thread..)

[JUSTIN K]

I have heard varied reports on workin the altessa motor as in it's very expensive to modify and i'm not sure but aren't they still in the $5000 price range? Add to that the cost of the actual conversion (and they are always cheap )
$5000 buys alot of machine shop time ! also I've heard the 6 speed is alittle fragile for anything over stock power but I've yet to get that confirmed by anyone that's had one behind more than 200 hp.
Thanks for the input.

Regards
Justin

ps - my dad had alfas - you are preachin to the choir

pps who's Glen? has he plyed with the altessa 3s?

[love ke70]

4a ftw...
or 3rz hehe that would be different

[JUSTIN K]

looked into the 3rz as well but was told by a wrecker here in melbourne that they are a shit performance motor. also couldn't get a weight for them. did like the sound of all those cubes though. anyone confirm they're a bad option?

[love ke70]

can buy crate 3rz built for 1200 hp....go figure...
although as stock. my mate put a t04 on one, which he kinda flogged off a diesel, doesnt make boost til 4000 and redlines at 5500 lol
so yeah, would prob have to work it...
but...2.7 l torque
and it probably wont weigh that much more than a 2t. which weighs a decent bit more than a 4ag
4ag is around 120
k motors are around 100
2t is 150 ish

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.

Even I don't know exactly how my engine builder did it, and I cant ask him any more but I do know it cost me over $5000 1982 dollars and involved machining new pistons down and lining the block as we cut into the water galleries and yes was basically a hand grenade and soon traded for something with less power but more reliability. But was great fun in a ke20 fpr the time I had it.

I have also heard of this being done although don't know how.

Hi,

If possible, and you have the money, just buy a 151E engine.

I know its great to keep some sort of old skool feel but it just doesnt go hand in hand with driveability and power.

A friend of mine used to have one of the Sean Moloney 2TG race engines in his TA22 back in the mid 90's with 200hp at the wheels,and while it sounded insane when going,you had to put up with problems starting and ildeing and the main chunk of the power came on over 6K....I really dont see the point when for the money you sound like your willing to spend on your car you dont go with a 3S and have 200 usable kw at your disposal.

The novalty of having an oldskool engine will wear off when some punk kid smokes you in his Susuki Baleno with hairdryer,neons and roof wing And when you pull up at the next set of lights he'll suggest to race for headjobs, cause in his mind having to give or take... Its still a win-win

Hi,

True words, my strange red-headed friend.

If you want to race and do that sort of stuff then an old school NA 2T-G will need to be modded to the point of being almost unstreetable. A mildly worked 2T-G will give your TA22 plenty of poke and allow for some spirited driving and great fun - and be very streetable.

However, the newer engines offer much more power and potential, and you can get parts for them.

But to me, the joy of old school is going the full old school route - that is, the looks and the engine - all back to original. I let the boy-racers whiz past 'cos I know that old school is cool. You don't need to drag......... you just cruise.

It's not always about speed and burning rubber, sometimes it's about class, cool, charm and grace - and the old school stuff has that by the bucket load. It's something the newer cars just can't compete against.

I agree,I just dont see the point in having that same class,cool, charm and grace after pumping 5K into the engine.

Leave it be and invest the money else where,like another car with the works
