hey all
im new here. i just bought a t18 unlic with 3t-gte for $1500.
im planning to spend some dosh on it to make it look a bit neater and perhaps some engine mods too.
currently it has a k&n pod in a box, small cooler with a 600x300x76 waiting in the shed, and a 2.5 inch zorst.
what (cheap) mods are recomended to make some more ponies?
i am thinking:
- 3inch zorst
- the big cooler
- 7m-gte injectors???
- more boost - how much is safe??
- turbo - dont want lag ie t3
cheers ppl

ooh and does the 3s-gte have the same exhaust manifold stud pattern as the 3t-gte?

Definately not.
Put a programmable aftermarket ECU at the top of your list for mods. The standard computer leaves a lot to be desired.

i bought it unlicenced in waneroo, perth.
ive been reading up and is it true that the 3t-gte computer is fuel only??
so upgrading it with say a megasquirt ecu eliminates the entire standard ecu??
how does the knock retard work then??
cheer people

put a ct26 on and u should b able to run 15 psi. with stock ecu and inj. runing on high octane fuel with no ping. I recommend getting a BOV. Coz I did.

I have front mount, CT20-B turbo, upgraded injecters / pumps, EMS, etc.
This isnt a very laggy setup and has plenty of power

What exactly does a "tune" involve, setting the points & base timing perhaps?

The stock computer does not suck as much as some folk think. You can run a lot more horsies staying with the stockie but you have to trick the afm sensor (not very difficult to do) and replace the injectors with red denso's, theres more but to save time...
Search for daytona's site on google and look for Matti's Carina running stock ecu making over 200rwkw's, no dramas. Lots of 3TGTEU info there. I would not bother running more than a 2.5 inch zorst on it LOTS of noise with questionably more gain
And altho i too wonder exactly what a tune might involve with stock ecu, RB20DET has a good point, start by treating the motor to as much freshening up and tlc as you can. Makes good sense and insures less heartache if and when things go pearshaped. Actually you have many of the mods I have yet to do with my 1980 T18/3TGTEU but at least mines regoed lol. Consider that you will have to get it engineered or at least passed over the pits and it might actually make sense to downgrade your mods until the pits Nazis have had a suss.

tune involes making sure timing is correct, it idles proplerly, adjust afm ect. with these mod i got 135rwkw on a standard motor. up from 99rwkw. duh what do u think tune means with no aftermarket computer.

Hey RB20DET, I think most folk think tuning involves playing with fuel etc on a aftermarket ecu (dyno). Some people would think that what you are talking about is just basic maintenance, like checking the oil and water. I do agree though it's good to cover the basics, as I said in my last post.

i had a look at the guts of a 3tgte today, you could get it to work with aftermarket spark control just by locking up the advance and then running 1 ignitor to spark 2 coils at the time triggered by the ecu

hey guys thanks for the replies.
ta-23 - you say you have a ct20-b turbo, whats the diff between ct20 and ct20b? eg less/more lag, better high end breathing??
yeah i know licencing it will be fun
im going to tidy EVERYTHING up before i take it to the pits. otherwise they'll spot a couple of faults and proceed to pull the car to pieces.
so putting on an aftermarket ecu - to have ignition control you need to remove the dizzy and make a new CAS? is this hard? i have no idea about the ignition side of things.
also what 1/4 mile times are ppl getting with similar setups? im hoping for around 150rwhp all day everyday with the ability to tow a trailer without tearing sideways when boost hits hard at 4000rpm
thanks for the info

Hey good to see another T-18 on here especialy with a 3TGTE . yeah like the others said clean everything up a bit wind a bit more boost 12psi is good my mate just got a RA23 he runs 12psi on that everyday and get that intercooler hooked up if you are going to be thrashing it ive seen those rubber fittings on the intake melt once on a sprinter going around a track that was on 10psi. i think the CT20B is just an unmarked CT26 with a ceramic turbine wheel. my mate also has what u could call a CT20B if they even exist and a CT26 from a 7MGTE but i am going to buy that one as it has steel wheel And both those turbos when sitting together look to be a similar size, i mean you might have to wait a little more for boost to come on but when it does youll love it. As for the stock ECU's ive been to daytonas website and seen that carina making 300hp with a stock ECU but i think thats probly been reprogrammed or something plus the cars from another country so there was probly a bit of miscomunication because i dont rekon they can support that much power but i dunno how well they actually work personally but ill find out when i put my engine in and do some mods fingers crossed they can handle a bit of power. the knock computer retards ignition timing on the engine to prevent detonation they are good as extend your engine life.

yeah upgrading with a wolf 2d or an old microtech or something like that will get rid of the std ecu and that way you can richen the mixture up a bit at certain points in the rev range so you dont lean it out when u run more boost.

CT20-B turbo's are off 3rd gen 3SGTE's (ie: ST205 GT4), they are alot bigger and better than the CT20. Pics can be found in the link in my signature if your interested.

I am not sure how rb20det got 135rwkw with the mods he listed, I am not saying he didnt, but with my mods i produced 155hp @ around 10psi. Although it isnt running very well at the moment.
Would be interested to hear your results though if you do decide to do these mods.

155rwhp at 10psi isnt far off 135rwkw at 12psi and dyno opertors can fudge readings a bit so u go back to them

Bunky when i said from another country i mean the carina was, well how do you know the guy with the carina didnt mention that he wasnt using the stock ECU or that he didnt actually know what ECU is in it, its just i havent seen another 3TGTE making that much power with stock ECU's and if they could why arent more people using them, i am going to be and i am glad that they run more rich than lean im not bagging them out im just being cautious to what they can really do, show me another car making that much power with a std ECU and ill be fking over the moon and keep mine forever. i just want proof thats all im not saying they are shit, why would i bag out my own car, and no i havent built my motor yet im waiting on forged pistons. but a good mate of mine's dad has been toying with 3TGTE's for over 15 years and they have owned several and ive seen them and worked on one etc and do research on this shit.

Hi all, just thought i should have a say in here too!, my 3T-gte puts out ~148rwkw on 10psi, essentially stock, other than well tuned microtech, front mount and good fuel, just cant get this battery\alternator thing sorted yet !...

so what are the best upgraded injectors with performance and price in mind? what size are the standard injectors? i want to upgrade but i dont want to spend shitloads initially buying them and having to mod manifolds etc.
so what have u guys found to be the easiest cheapest and most effective injector upgrade?
also, i have a microtech ltx, im not really confident hooking that up to the 3tgte myself, and i cant afford to get it hooked atm...could anyone help me out or give me some advice. if anyones in victoria id quite happily pay them.

Thought I'd give my 2 cents worth on the 3T GTE.
I had a fair amount of correspondence with Matti a few years ago and I also mucked around with the stock ECU and did get reasonable results. Around 125rwkw. In the end I used bigger injectors as well as using the stock 3T GTE AFM internals and fitted them in a 1GGTE AFM cause its about 25% bigger. Then I fooled the AFM by tensioning the spring. This does work but its nowhere near as good as an aftermarket ECU. Mainly cause you have to tune the stock ECU for top end power and then it comes at the expense of poor idle, cold start issues etc. Or you can get it better down low and then you lose out at the top end.
No doubt Matti pushed it to the limit, and his engine would have been on edge the whole time. Also, he was very good with electronics, much more than most of us. So I think its easier to give the stock ECU a miss. Its old technology and really not worth the hassle in my opinion,.
I now has an LTX8 Microtech and have 145rwkw at 14psi. Still running stock internals including pistons. Full details are on my site.I completely wired the Microtech and had it running in just over a day.
Cya,
Simon

im sorry too bunky ive never really used one myself yet. i know what u mean about 3TGTE's having varying power outputs as they are over 20 years old and most engines that havent been rebuilt over that amount of time compared to a freshly built one are going to be alot different depending on how the older motor was treated.
TA22 GT thats bloddy good power out put, is that using a ct20? or larger turbo, what other mods did you have

Mods don't always equal results mate. At the end of the day it's the basics of engine building and performance that make for the fast times and big dyno runs.
Plenty of 'modded' cars out there that deliver weaker figures than the same car stock...
|
I understand that modded car can deliver less than stock performance results, but the mods I have done to my engine are upgrades that plenty of 3TGTE owners have carried out to their engines and have had good results.
I dont see how an engine rebuild, upgraded fuel system, ECU, Bigger high flowed turbo, exhaust etc etc could yeild less results than a stock 3TGTE. These type of mods are carried out by all car enthusiasts to increase performance.
My car still has a few issues to sort out, so I am expecting more power from it, but I was just a little shocked to see such high power results with only the standard turbo, one being almost 25rwkw more than mine @ same boost pressure, yet the turbo on mine is alot bigger (without being too big) and highflowed + associated mods to cope.
Could you please explain this?
Cheers,
Mitch.

I have bigger injectors, Microtech LTX8 ECU, EVO 5 intercooler, BOV, custom exhaust manifold with GT25 BB Turbo, full 3 inch exhaust and all stock internals.
Currently making a CAS and custom intake plenum, aiming for around 200rwkw.

fu*king wicked im just rebuilding mine at the moment waiting on these bloody rods i wanted H beams but i just got stocks and i might shot pein them but i am getting forged arias pistons when i send a stock one away to them, So later on i can get a fair bit more power and dont have to open the engine up again. but 200rwkw from a 3TGTE would be a very frkn nice thing a achive.

Mitch;
Mate I'm not pretending to know the nature of your mods and for all I know they may be the ducks nuts. My point was that it is actually common for stock setups to beat modded ones. There are a number of reasons for this ranging from dodgy Intercooler piping, heatsink etc, to incorrect tuning. Of all the things that can go wrong, I'd say it would have to be the tuning of an aftermarket ECU rating as the number one stuffup for modded cars. If you are really interested, read Julian Edgars '21st Century Performance' to give a more detailed rundown. Julian knows what he is talking about and has been a Tech Guru for various motor mags over the years and Edits 'Autospeed' online.

Yes I do understand that stock setups can produce more power and out perform modded examples of the same engine, when you said......

I got the impression that you were directing at my mods etc. and was just curious how this added up.
Anyway putting all this aside, I would be very interested if anyone could recomend any workshops who know the 3TGTE motor well, would be looking at a possible re-tune (if needed) so knowledge of Haltech computers would also be a bonus.
Am from Wagga Wagga, would be looking at workshops in the Sydney area, or closer to me.

Hooking up the ECU needn't be that hard; can you hold a soldering iron, and do you know how heatshrink works?
