My Turbos are ment to be finshed and back to me by next week (only been like 2 months)

I'm considering upgrading the exhaust manifold while the turbos are off.

I saw the Tomei kit on nengun for $1144 delivered Tomie Info, I thought it seemed pretty good. The kit comes with a heat Bandage, Clamps, and most importantly Stickers :D

But i'm also considering the UAS honed and heat treated stockers for $790 + delivery.

Is the tomie kit worth it, or is it just paying for a Jap brand? Or should I keep the stockers?

The reason I was wanting to upgrade is cause the exhaust housing on the turbos is ceramic coated (there the old 2530's from the Paul and Stacey's car), and I thought I might as well get heat treated manifolds to go with them.

Thanks

Id try the unique manifolds, as heat retention is the key to aiding gas velocity....and the thick walled cast manifolds do a superb job of doing that, do you know if they are ceramic coated as well?...good luck with the upgrade....those little turbo's sure were good for us...i hope they serve you well.

the UAS site says that they're HPC coated, is that ceramic?

Yep id go for them for sure, the coating is worth $300 a pair, the extrude honing is probably about the same. So to save yourself the trouble of doing it yourself....get em.

Looks as though they leave the lip into the turbine housing there. Wonder why? Cuts into the flow at least 4mm.

Tomeis look nice though. Investment cast tubing. Would be a real dilemma to decide.

The stock manifolds crack around the outlet if you remove much meat from there...that's probably why.

    • Yes, but it's not as easy as pulling a fuse on anything other than an R32. There's a routine you have to do, involving disconnecting a loom plug and bleeding down the preload.
    • A question for tuning awd, is it possible to disable the AWD? The stagea is an EA/T AWD, Toshi had said on a GTR, he was able to disable it and make it 2wd. Just wanted to double check if this was possible
    • 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
