ATB Posted June 7, 2014 Share Posted June 7, 2014 Hello I have a few questions I was hoping to get some help with. Car is a stock 2JZ-GTE TT. 1. I got a very good deal on a HKS Hi-Power silent catback and I was wondering if it is just to bolt it on and drive? I don't have to worry about higher turbo pressure when deleting one of the catalytic converters? (I actually read that on here and got a bit concerned...) If I do get more boost does the car adjust itself? I also don't have a boost gauge so it's no way for me to tell if there is any change. 2. It has been very hot here lately and I have been running with the AC on a lot, but when i turn it off the air that comes out off the vents gets very moist so I either have to use the AC 24/7 or have the windows down. I searched around and I came to the conclusion that the supra does not have a cabin filter so that can't be the issue... any ideas? Quote Link to comment Share on other sites More sharing options...

Benjy Posted June 7, 2014 Share Posted June 7, 2014 You may occasionally hit fuel cut with the first cat in place but it's not detremental. I would bin the 1st cat, get a FCD, boost controller and a 1.2 bar restrictor ring. Change the fuel pump and spark plugs too and you're BPU.

ATB Posted June 7, 2014 Author Share Posted June 7, 2014 That was very informative, thank you! I am only looking to do the exhaust as I am not allowed to change anything in the engine bay (Could lose my licence plates if i do). Could I use the whole exhaust shown in the picture or should I only do the catback? This is a US spec car with the steel turbos. I am new to turbo cars and I just wan't to make 100% sure I don't do anything that will ruin the engine in the long run. Quote Link to comment Share on other sites More sharing options...
Nic Posted June 7, 2014 Share Posted June 7, 2014 The cat back exhaust will be a straight swap, as it's a US Supra, swapping the exhaust and even removing the cats won't effect the peak boost level. Quote Link to comment Share on other sites More sharing options...
