having equal lenth pipes means that when you are punching along you in theory are moving the exauhst gases out of the turbos equaly. honestly i dont feel that you will be able to notice the difference in power wether there equal or not!

some one may think different though.

wow there are some exciting shapes in those pics!

:bunny:

exhaust pulse tuning matters most after the port - on an n/a motor it's really significant because the gas path is unimpeded, and scavenging and engine characteristics can be enhanced/tuned by fiddling with pipe length, diameter etc. when you have a turbo whacked into the path of the exh gas it's pretty much all over as long as resistance and turbulence are minimised after the turbo. i've got equal length on my gtr and to be honest i'd rather do without the spaghetti and extra weight.

any more thoughts ?

Getting my new system custom made tomorrow morning. It will consist of twin 3" front pipe through 2x3" magic cats and then merge to 3.5" Cat back. I will be asking for the Y pipe to be as slow transitioning as possible....since 2 three inch pipes into a 3.5" would speed flow up in a hurry

fair enough.

well when thinking about it..

its no longer a pulse once it leaves the turbo housing, so aslong as it is a smooth transistion it shouldn't affect the flow too much.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
