I have purchased some 42mm stainless extractors for my RB26. On inspection I found the turbo outlets to be alot larger than std manifold(about 10mm). Feeling inside the std manifold you can feel the deliberate angle to reduce the oulet side. I have 2530's fitted which have an exhuast inlet size 3 or 4mm bigger than the Std housing , but, alot smaller than my new extractors still. Nissan have obviously designed there manifold for higher gas speed. I would have no issue's enlarging the std manifold slightly to match the 2530's however I am reluctant to enlarge the turbine inlet to match my stainless extractors and risk increasing lag... Has anyone been in this position before?

Interesting subject, as i'm about to fit stainless manifolds to my gtr as well but do not have the turbos off at the moment to compare them to the manifolds. You might be better served by having the manifolds welded slightly and then die grind them to match the turbo housing. Just a thought, instead of altering your nice turbos.

    • Thanks for the info. The only "Issue" I've had with the shifter is I always found the throw between 4th and 6th gear too close. I'm always worried to shift into 4th accidently and sending my motor to the moon. Adam LZ recently came out with a video and stated Serialnine revised their shifters to correct this and will change all the revised parts for 150$. Strangely enough, I contacted Serialnine right after and they denied it and said it's bullshit. I found that strange as he's a distributer. I'll keep this forum post updated on that saga.
    • Yep that is correct. It allows you to adjust the short throw range from what I can tell
    • Car has been running great, I've put about 300km's of break in time on it. First thing that stands out with properly sealing rings is no more noticeable crankcase smell coming out of my catch can. This may seem insignificant, but the constant smell while driving around was infuriating. It's also nice to see my oil level remain stable. Two new issues have developed that I only noticed this weekend though. There's a very noticeable driveline vibration past 100kmh. I only noticed it now as I've been babying it under 100kmh in the backroads. This comes as no surprise as I'm running a one-piece shaft, and I paid zero attention to my driveshaft angle when I put everything back in. I also have a fair bit of voltage drop on hot starts. The starter audibly is forcing. No issues on cold start though. I must not have removed all the paint under my main block ground during assembly. I'll try and take care of both those issues this week once the kids are asleep.  I also received all the parts I was missing for my direct port setup. I will hopefully have pictures of that up soon. I'm hoping to get back on the dyno the week of June 30th as I'll be on vacation. I'm confident I should be able to make north of 500rwkw on pump gas and WMI. I'll go back again later this summer with E98, but I want to confirm my ethanol content sensor is working properly first. I've never seen it read anything but 11%. This makes sense for our 10% ethanol content pump gas here, but I would expect the occasional movement between fill ups. 
    • 75% complete. Will now need to get a new axle with 5x114.3 hubs and then figure out how to customize some mudguards for it once the wheels are on.
    • Trailer prep is underway... Lined up the wheel to get a rough indication of how it would sit Then removed all the bits (as far as possible) and gave the frame a light sand and quick lick of paint   Then added some carpet
