the damn coupler keeps popping off, its the 3rd time ive have to tighten it in the last week. im running stock boost, so any guys want to reveal their secret of keeping their couplers on? super glue? hehehe

 

try using a t-bolt clamp instead of the regular "screw" type

 

maybe cleaning off the coupler and the pipe might help too.

 

You could sand the pipe end with rough grip to try and get soem more grip for the coupler. or get a shop to lip it for you.

 

The stock crossover pipe?

 

Cleaning it has worked for me. I just use some brake clean on a cloth and wipe all sufaces clean and dry and also replace coupler with a silicone piece. Do this every time you take it apart, oil gathers around that area a bit, so when you take it off then put it back on its slippery. What would be nice is the all aluminim one from I believe the 1999 RX-7 (Efini), it has a face seal instead of the clamps.

 

yes i still have the stock ic and stock piping, thanks guys for suggestions...im gonna just work on cleaning the area up a little better and see if that will work better.

 

Get the improved Y pipe and cross over and be done with it.

 

can the ypipe swap be done without a lift? .

 

<edit> Yes, you can change it without a lift.

 

If you're running stock boost, i dont see how its coming off unless you either didnt tighten the clamps on correctly and/or using shitty couplers/clamps.

Get some hose technique couplings. They are awesome.

 

thanks, ive been reading up on the y pipe. read that it increases boost but does it cause you to creep?

 

im using stock couplers so i guess they are shitty i believe im tightening them down correctly its not rocket science, getting them in the groove of the coupler and screwing them down...tight!

 

FYI, if you ARE using shitty clamps, tightening them TOOO tight will cause them to pop loose. Maybe you arent aware of this as you overdid them and they havent popped until you boosted.

 

yea this last time i probably over did it as you say, because it was a significantly louder pop when it came off

 

does jason have the couplers?

 

what is the ID of the stock coupler? is it 2.5" or 2.75"?

 

I dont think he has them for intake, hosetechniques do though.
