little num Posted April 5, 2010 Share Posted April 5, 2010 Hi guys im fitting a 1JZ into my n/a and have took the decats off the soarer to find there is no restrictor ring fitted, now i realise the turbo's are smaller then j-spec supra's but id have thought it would still require a 1 bar ring fitted, soarer guys or mk3 owners might be able to help.

rockatanski Posted April 5, 2010 Share Posted April 5, 2010 Hi, I´m running a decated 1 JZGTE in my soarer and it spools up very quickly with a full 3 " freeflow exhaust. A resrictor ring will be a good idea and perhaps a EBC like an apexi avcr... Greets Rocka Quote Link to comment Share on other sites More sharing options...
Stealth-1JZ Posted April 6, 2010 Share Posted April 6, 2010 im runing a supra decat 2.5" i think and a full 3" back exhaust along with a EBC set 1/1.1 bar with no drama Quote Link to comment Share on other sites More sharing options...

shima60 Posted April 6, 2010 Share Posted April 6, 2010 yup. on my soarer i have a 3" pipe going straight from turbo to backbox with no issue's and on a blitz boost DSBC running 1.2 bar no problems here... goes like stink to Quote Link to comment Share on other sites More sharing options...
little num Posted April 6, 2010 Author Share Posted April 6, 2010 tidy, really looking forward to getting this in and running 1.1 - 1.2bar, is it worth fitting water injection as i have the kit anyway. Quote Link to comment Share on other sites More sharing options...

MaccyD Posted April 6, 2010 Share Posted April 6, 2010 the reason i heard a restrictor ring is required is to prevent a boost spike that will cause the seals to go on the turbos. im dropping the same engine in a 200sx and will just be using the cat as a restriction, hopefully thatll be enough.

The exhaust being removed is enough to pop the seals, once that restriction is gone the amount of shaft play in tired bearings causes the seals to go, its not really boost related.

I will be running a standard downpipe and y-pipe so do you think that would be ok or do you think i will need to leave the cat in for restriction? i dunno if it changes anything but my downpipe will also be at the standard diameter for about 1-2 feet more than standard as i have to drop it across to the other side of the car to the standard position in my nissan.

rockatanski Posted April 7, 2010 Share Posted April 7, 2010 decat -> restrictor ring or ebc set to 1,1 - 1,3 bar no boostlimit - > turbos will be dead soon Mine last with 13,-1,4 bar for 27 tkm after 147 tkm oem configurated ... but they are dying right now ;-( Good luck Rocka Quote Link to comment Share on other sites More sharing options...
