Origanally had 5.9, 3, 5.9 and sum times 8,5,5.

have replaced all hoses with new silicone hoses.
checked all valves, and have checked all boost pipes.
have checked every thing on the "how to" sites.
both 1" pipes have been changed cos i found them cracked and loose.
any ideas are helpful thankyou.

im starting not to trust the boost gauge.

also after i reasembled and tested the car, after switch of i can here a bubble sound from under the rats nest. ive taken it apart but carnt find any leaks. is this normal or just air in water system from removing inlet maifold extension???

 

Sounds like your cat is clogged.

The bubble sound is either a fuel leak or air in the coolant system.

 

Check your pre-cat, that's normally the first thing to clog on the exhaust.

 

Since when is the precat or any cat located on the intake?

 

what are you talking about?

 

Oh rite.
how easy is it to take pre cat off.
and am i likely to sheer the bolts/nuts

 

HAHA. Too late, you have been caught before the edit.

not difficult but shitty job,and yes very likely to sheer nuts,since its near the turbo the heat can cause the nuts to seize/freeze ,oh yes you will also most likeky sheer youre knuckles doing that
have fun
btw precats in intake????

 

Have now removed down pipe but there is no pre cat.
do jdm rxs have them. or has it been gutted. its not after market either i dont think.
Any new ideas on the boost problem
