does this make any real difference when not chasing silly numbers ?

I was just thinking that for the price of a couple of metres of alloy pipe and a day or two with the welder out etc i could improve the breathing of my car.

 

Anyone here actually done it or is it all internet rumours ?

It makes a massive difference,helps with torque and spooling,trust me it works.pita to fit though.

How big could you go?

If you speak to a lot of the us guys they are making good numbers on stock turbo 2.5" inter cooler pipes and 3" exhaust system, that combination makes a real difference with the appropriate tune of corse

So youdone it Jimmer ? as i said im looking for real world epxerience. Ive read so much BS on the net it gets to the point you cant distinguish whats real !

I may give it a go as my intercoolers have 2.5 inch inlets/outlets.

I just need to buy a beading tool so pipes dont pop off !

if your making the pipes your self u can just add rim spots in the outer with your welder .. as the bead is not there for the seal just so the pipe dont slip off

saves u buying a tool ..

 

and in the real world yes it does make a huge difference

i usually weld a bead right round when i do it, but its time consuming ( i dont lke spotting as it can allow leaks) found a brand new tool for 150 quid so if all the bits ive got for sale go i can order it and hoses etc.

i just seen the price of the american 2.5 pipe kit !

wtf thats a ripoff, its about 50 quid worth of pipe in there !

Have a look on aus300zx.com under the user name mungyz, he designed a kit and did some dyno testing with it, definitely made a difference!

so far ivm halfway through the 2.5 inch intercooler pipe test and mungzy is claiming the 2.5 doesnt provide any benefit....

Ruishy,

 

Not been around for a while but my Z has the full Ash-spec 2.5" intercooler piping set and Massive intercoolers. It has not been on the road this year due to me being very busy and the garage not fitting part of the kit where the recirc valves need to be plumbed in properly. I only found this thread as i am heading round this afternoon to see what needs to be done to get it back up and running and was doing a google for some pictures/instructions! If you want to see a set that is fitted feel free to give me a call 07775591043. I am based in Glasgow.
