Hi guys,

I was thinking, my car is running on a t3 turbo now with an untuned MOTEC.. if i go and tune it now.. and when i get a new t3 which is a direct swap.. does it need a retune again? or can it run on the same settings coz its the same turbo just a new swap?

Cheers

Bernard

T3 doesnt really tell you much. If the new turbo is the exact same specs and flows the same amount of air then you shouldnt have to but if the specs are different then you will need a retune.

sorry i dont really know the exact specs until i go check it out.. i think should be a TRUST T3 turbo.. thats all i know i guess.. im a noobie :banana:

If i get my mechanic to take the turbo out, he would be able to check the specs of the turbo and probably order the exact same one for me so i wont need a retune right?

I heard running a car with an untuned ECU is bad.. real bad.. even if i granny it.. am i right?

Cheers

Why would you be pulling the turbo out to replace it with the very same thing? Is the current turbo stuffed?

If there is a problem with the current turbo, logically you would wait until you swapped them out before doing any sort of tuning.

hmm.. thats very true.. but its just that on my current budget i cant do both at the same time.. and i still need the car as a daily.. so i figured tuning it first so i can still granny it and use it as a daily for now..

What about rebuilding turbos? is it worth it? would it be expensive?

cheers

i just gave a call to per4manz and they quoted roughly about 700+ for a rebuild, machining and adding a 360degree (something) to the turbo as im gonna be boosting it at 1.2bar once its tuned.. thats roughly about 15psi am i right? would u guys reckon i rebuild it or get a new one.. coz its already a high mounted and its the seals that are causing the problems..

I heard getting a same new turbo would be almost double the price..

umm no. 1Bar is 14.7psi.. so 1.2 Bar is probably closer to 18psi..

u need to do research before u change anything or boost anything.

read up about what most ppl put on theyre rb20's, and what is a direct bolt on so u dont have to change anything else.

and trust dont make anything with a T3 footprint.. they use theyre own size last time i checked :cheers:

mate that's really your choice... if you have the money for a tune now chuck it away in a bank account you cant touch till you upgrade turbo.... if you really need your car for a daily then save your money and do it at once....

      I know it's an entirely different engine, but I noticed practically 0 difference removing or adding 2x 3in (5inch body) 400cell cats (one in each bank) with regards to sound. So changing the cat to change drone I suspect will have very very, very, very, very, very very minimal impact.

      200 cell cat will probably help. Do you have room to tee off a Helmholtz resonator anywhere along the exhaust? These can do wonders for drones, with a little experimentation with regards to length.

      The car revs up through the gears much better/faster now, and fuel consumption doesn't really seem to have be affected either on a Hwy cruise, which wasn't expected  The FAB9 intake manifold has been problematic sourcing though, I've contacted Plasmaman to ask about their intake, which you can get different runner lengths spec'd, and, their different options for throttle bodies  The only real physical drawback with the Plasmaman intake is how to connect it to my current OEM style airbox, as FAB9 make a OEM style back half of the airbox to suit the larger diameter throttle body, and all that is required is a 30°bend silicone pipe to mate the throttle body to the airbox Car also goes in for some exhaust work in a week or so to fit the biggest resonator they can fit clearance wise in the front pipe to help remove some of the drone, there isn't alot of realestate under there, a rough guesstimation is it will only be about 3-400mm long and maybe 90-100mm diameter, and with a 60mm exhaust that doesn't leave alot of space for the internal volume of the resonator to do its thing I'm thinking I may need to bin the "high flow" 100 cell cat for something a bit more substantial, yeah, and restrictive, like a 200-400 cell, to help, but, I have ample room for a really large bodied cat to replace the current one which has around a 4" diameter body I may look around in the recycling bins and see if I can find a massive newish cat that was "replaced" with some new full exhaust system that the local exhaust shop in Western Sydney is doing

      Hahah look at that smile 😂 Just like those ones on IG where they compare the husband in family photos vs husband going fishing lol. I don't think I'll participate this time, clutch isn't in and also the last time I went there were too many numpties on the cruise sessions. Nearly caused a few accidents holding up people and a few guys initiating massive kerb to kerb drifts with heaps of cars right behind them. Not to mention, there were guys on the track session using it as a power cruise session.
