Performance mods in Australia

[jakecelica]

Hey guys, I’m new to the forum. Planning to modify my 2002 celica with performance intake and catback exhaust. What would y’all recommend that’s easily obtainable in aus.

thanks 🙂

I had one of those but never modded it. I know the scene is bigger in the US for those so maybe try newcelica.org

MWR is a good source (albeit not cheap) for all things 2ZZ, at least engine-bay related.

 

As for the exhaust, for a catback you'd probably be best off just going to your local exhaust shop and getting something made up with a Lukey or Magnaflow resonator + muffler, no point shelling out hundreds in shipping for a JDM special from the land of the rising sun when the gains will be the same.

In terms of intakes, a mate of mine makes them in his spare time down Vic and I'm sure he's done a few Celica's in his time.

As for exhaust, couldn't have said it better than Ian. Depending on what yor future plans are with the car, a 2.5" system will yield some nice gains albeit, losing a little low end on the stock tune. Another worth while upgrade while you're doing the exhaust is porting the standard headers, it's not overally expensive and does reduce the low/mid range flat spot you may have noticed. I had ported headers on my Sportivo a few years back before upgrading and they're definitely the best bang for buck upgrade in terms of cost vs gain.

Wonder if he'd feel like knocking up one for the ZZE102...

 

Word of warning for intakes though, the stock MAF/ECU combination is very sensitive to pipe diameter and shape.  Going larger than stock or adding bends in the wrong places will through CEL codes and can cause poor/rough running.

It's nothing flash, it's purely functional but I'm not entirely sure how he'd get around a AE102 with a 2ZZ, that would be a first for him 😅 I mean he modified my injen as it was shorter and fit much better, well for the 2 piece intake that is.

My current setup is the 3" with the 2.75" reducers at the MAF but I'm thinking of keeping that aside now that I run MAP. The pipe itself is actuall a Injen pipe from a blob eye WRX but it uses the same MAF style so it works for our cars too.

As a starting point I'd honestly advise a full 2.75" intake but, I do re-call reading/hearing that the Celica's are bit more sensitive to intake changes compared to Corolla's. I remember reading people running AEM CAI's couldn't run the Injen CAI because it needed a tune to run them, or something along those lines and I always assumed they were the same size from what I found online.
