honestly calaisturbo.com will get you further, but no, you will need an intercooler for almost anything over 9psi with the stock turbo and perhaps 12 psi with aftermarket turbo, dont muck about without one, intercoolers are cheap as chips these days. your loking to run a larger crossover pipe??? methanol, lol

there would be no point upgrading the crossover pipe unless you were upgrading the throttle body to

^^ this.

No point in upgrading any of the cold side piping unlesss going to a bigger throttlebody.

i think really, the point is, throw away the crossover, because you will need an intercooler to make close to 300rwkw in a vl :thumbsup:, for the sau guys that may not know, crosover pipe means no intercooler......

In the skyline world a "crossover pipe" refers to the pipe that crosses over the engine to go to the standard clamshell intake manifolds on RB20/25's. Also sometimes referred to as a J-pipe (due to its' shape).

on standard VLs the xover pipe acts as a homo intercooler, it has heatsoak fins on it and shit

yea, sorry i was assuming you ran a sohc rb30 turbo, which, as mentioned has some "cooling" fins as an "intercooler", but basically its a piece of pipe from the turbo to the throttlebody without an intercooler.

As you have a rb25, continue on, clearly i was on a different page :thumbsup:

    • Whoa, that's a name I've not see for a long time! Sorry to hear about the engine / turbo damage.  Fwiw with any engine problems it often really a case of just seeing what happens when it's apart, ymmv - I wouldn't rule out the possibility that the damage isn't even from the turbo failure, or possibly from a combination.  The airflow between cylinders isn't dead even, injectors can go off over time as well, with the turbos overboosting if you didn't have upgraded fuel system there could have possibly been a bit of leaning out - stock triggering is often a bit unreliable by this age too.  Basically its an old engine and a few things could have been going on, and you won't know how much work is needed until the engine is apart.  
    • I'm just shocked there's a euro driver on our roads who is thinking of other road users and not attempting to blind everyone. I wonder if Prank uses his indicator too...
    • Its hard to tell really. The Q50 owner's forum talks about it a lot and has quite a few people directly affected, but no idea what % of cars sold actually had the block replaced. Also, there seem to be 2 distinct issues which both get diagnosed by Infiniti as requiring a block replacement (no wonder they are going broke) 1. "Porous block" where coolant mixes with oil through thin or poorly cast parts of the block 2. Head coolant gallery plugs not sealing. If I was noticing engine coolant loss I'd start with cooling system pressure test (as always) and then I'd pull the cam covers and reseal the coolant gallery plugs on both side before worrying about a potentially porous block.  If neither of those did the trick it would be put in a second hand engine out of japan; I haven't checked pricing but I'm sure there are plenty around by now as they've been in production 10+ years
    • To clarify what I posted above, I thought you both had a situation where it cancelled sooner one way than the other.....if it is reasonably even where it cancels in either direction that is probably normal (consider gentle movements like lane changes, you don't want it to need half a turn of lock to turn the indicators off)
    • Son, in this country, that is a piece of Gyprock. f**king drywall. FFS! I also like the autocorrect of trailer to tablet. I was reading it and thing, "what the hell drugs is he on?" Then the photo made it clear enough.
