3SGE questions

[Caveman]

My car feels a little flat for what it is. Im running a gen1 3sge with TVIS intake ports and not major mods. I've just been out and theres a hill I like to test on which is about 150m long and quite steep. I drive from the bottom to the top and see how fast im doing at the top. The results

My mums 5afe corolla 4 door manual (rated 80kw): 70kmh
My GTR celica auto (rated 120kw): 75kmh

My dad recons the injectors could be screwed. Im thinking of replacing them but don't want to if i dont have to.

Were going to take apart the head over the christmas holidays to do a valve grind and polish (i've been told not to port a big port). I'm thinking of replacing the tvis manifold with a small port. Would this make any extra power? Would there be any complications?

I know this sounds very general, i've done a search but didnt find much, but are there any other problems that could slow down a 3sge.

Thanks in advance.

Before you try new injectors, try some injector cleaner. You can get it for like $12 from Repco and its enough for 3 tanks worth.
If it doesn't make much of an improvement, its no biggie, only $12. Better than buying new injectors to find theres bugger all difference.

Of course, if then injectors ARE stuffed, the cleaner isn't going to make any difference. But yea, its a cheap test

try timing, fuel filter, plugs, dizzy..
all them things and some other thigns im sure others will post..

i'll go with timing for now tho..

The auto really kills the performance aye, try to find a 5-speed ST162 at pick a part and grab all the bits for a manual conversion, my first car was an ST162 GT and it used to love hills, I had a few basic mods and it felt quite a bit faster than both the 20v's I have driven and my old AW11
Any additional power the ST182 has is offset by the weight and so i would stick to the engine you have and put your money into the manual conversion.
If the injectors were leaking then you'd be overfueling by quite a bit and you'd probably notice a lot of black smoke and if one or more was stuck closed your engine would've died from detonation already.

Will a st182 manual box fit in a st162. I know (from what i've read) that all S boxes mate up perfectly but what about the mounts?

Has anyone done this conversion?

Is the car FWD? (I'm so ignorant tonight )

I've got a spare corona box in average condition..... somewhere.

[Caveman]

Yea its a fwd.

Is the conrona box complete? I'd be very interested. The condition doesn't matter too much as long as all gears work and the synco's arn't too bad. I don't really trash my boxes.

I assume its a 5 speed?

[Chickenman]

I think you may need the clutch forks? I think the $&#$% at the workshop broke them. It didn't like changing into second from third that much... but wasn't too bad.

5 speed.

Also not sure about clutch/pressure plate etc.... Haven't had a look since I got my car back.
