Yakky Posted April 19, 2011 Share Posted April 19, 2011 There is only 1 cat on a 1JZ TT, down underneath the car, just before the "rear-section". Link to comment Share on other sites More sharing options...
ray007 Posted April 19, 2011 Author Share Posted April 19, 2011 There is only 1 cat on a 1JZ TT, down underneath the car, just before the "rear-section". Well basically I have a 1jz in a supra Mkiv with 2nd decat for supra installed, need a decat for the soarer cat then I guess Link to comment Share on other sites More sharing options...
little num Posted April 19, 2011 Share Posted April 19, 2011 The downpipe off the turbo's are all empty pipe's, they have a flexi welded in the middle to take stress off the manifold. I dont have 1 at the moment sold the last 1 to another member on here, if i get 1 shortly ill pm you direct mate ok. Link to comment Share on other sites More sharing options...
Swampy442 Posted April 19, 2011 Share Posted April 19, 2011 Whifbits dude? http://whifbitzperformancetuning.co.uk/toyota-soarer-exhausts-down-pipes-garage-whifbitz-p-1679.html Also rumours persist a Supra 2nd decat pipe fits fine but personally Ive never tried it Link to comment Share on other sites More sharing options...
little num Posted April 19, 2011 Share Posted April 19, 2011 swampy thats the second decat pipe, he needs the first down pipe off the bottom of the turbo's. And yes the 2nd cat both on the soarer and supra are exactly the same so obviously the 2nd decat pipe will fit, and thats the link you put up 2nd decat. Oh and just to let you both know the 2JZ 440cc injectors are a direct fit and work fine once the ECU has learnt the starting flow as when first installed the ECU will over fuel the car loads and normally flood it, once learnt its perfect.

ray007 Posted April 19, 2011 Author Share Posted April 19, 2011 Ah thanks buddy, 440cc it is then Would I need the fuel rail to go with the 440cc injectors or can i fit them To the stock 1jz fuel rail? And would I need to install a resistor pack?swampy thats the second decat pipe, he needs the first down pipe off the bottom of the turbo's.

Andy-No-Knee Posted April 19, 2011 Share Posted April 19, 2011 1JZ fuel rail is fine, and if you use UK Supra 440's then no resistor pack needed. Getting a bit confused on what you need, 1JZ's only have the 1 cat, which is the same as the 2nd cat on a SUp. The down pipe bit can also be supplied by Whifbitz iirc, when I was last there I think Paul showed me both lots. By the way, the workmanship on the pipework he sells for the 1JZ is awesome!!!

ray007 Posted April 19, 2011 Author Share Posted April 19, 2011 Thanks sooo much guys... Basically I don't need anything, I thought the 1st/downpipe was a cat... So I've been running full decat without restrictor ring... Damn I I need to install the boost gauge I have, probably would have noticed overboost, hence why one of my turbos is on it's way out Thanks soo much everyone Link to comment Share on other sites More sharing options...
