Choice, been watching out for an update on this.

The manifold is looking nice all ceramic coated. Looks really tidy from what I can see.

Very clean job on the wastegate inlet off the turbine housing too. Have seen some butcherous jobs on those before.

Haha, that side of the engine bay is going to be packed as when it's all assembled.

Glad you are still working on this. It's been a while in the making but I'm sure it'll be worth it as soon as you can give it that first squirt eh. Bring on the chubby ass power curve.

Starts taking bets on how long it will take before this one is gutted and caged too.

Yeh the manifold is not too shabby. If I had spent more time planning it out It could have been done a little better, but its going to have to do. If i was doing it again I would change the merge angle of the collector so its closer to ideal around the 10-15 degree marge rather then the 25-30 degree its at now. I was worried about it being too close to the bonnet, but it appears to be further away then expected. Live and learn.

I can say when its all in and going there literally wont be room for anything, at all.

Certainly has been a long time. But its getting there. Im hoping for the same thing!

Lol there should be enough room for everything I need, I think. It is going to be a little tight where the outlet of the turbo goes into the charger inlet though. I will cross that bridge when I get to it :) But its very safe to assume the engine bay will look full!

Chris, I was given that one, however im told you can get them from a company called Midway Metals. MIght be a good place to check if you are in need.

Lol yeh I should have purged it, but I was too lazy to machine up some bungs. I seem to like doing things the hard way lol. If I was doing this all at work then I would have as material and machines would be there. But its done now.

Took forever to weld it.....stupid lobster backs.

Its steps back down to 3" to match up with the existing system I made when it was just supercharged. I didnt really wanna fork out for more mufflers and redo the whole system in 4". This will have to do!

Its not an ideal step down either, its a 60 degree step rather then the proper 15 degrees or whatever its supposed to be. The first expander is more like what it should be.

Looking sweet!

was that cone hard to source?

It's a tube reducer. You can get them concentric and eccentric. Available in 304 or 316L

Excuse my intrusion; back to the show!

Cheers mate.

Well wastegate outlet is all tacked up, ran out of time to weld it. Lol no pictures sorry. However I have spent the last 3 hrs at work this morning working on the charger intake flange to accept a 3" tube to hook up the turbo outlet. Starting to take shape, Its going to be tight getting the turbo outlet plumbed into the charger intake though :wacko: .

      Stagea Front CV Axle Question

      By soviet_merlin · Posted

      One year is a bit concerning. Did you try contacting GSP? It says 5 year warranty on the box if I remember correctly. I'm also running their driveshafts on my S2 Stagea.   You could check the part numbers on Amayama for your year. Here's the link for my 1998 which gives the 39100-23U60 part number. Well, that and 39100-23U70. https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6649-rb25det/trans/391 What does it say for yours?

      Stagea Front CV Axle Question

      By S1_C34 · Posted

      I ordered a GSP Front R/H Axle from here - https://justjap.com/products/gsp-premium-front-driveshaft-r-h-nissan-r32-r33-r34-skyline-gtr-stagea-4wd#description It lasted around a year before one of the boots blew out. I'm lowered, but I have GKTech roll center adjusters. One year seems a little premature. I think I'm going to spend the extra money on an OEM cv axle this time. This website - https://tfaspeed.com/collections/nissan-stagea-wgnc34-x-four-parts/products/nissan-stagea-awc34-260rs-rb26-right-front-axle-drive-assembly Makes it sound like the readily available OEM CV axle will only fit 11.1999 Stagea and up (mine is a 2.1997 S1). The JustJap listing didn't mention any years or anything for the GSP axle. Amayama shows '11.1999' and up as well for that part number. As well as 'plastic boot type'. See attached picture. So I guess my question is, does that axle (39100-23U60) really only fit S2 Stagea? It's the front driver side. If it does, I'd love to buy that instead of rolling the dice on another GSP. I've found that OEM one cheaper here: https://www.partsfornissans.com/oem-parts/nismo-jdm-r32-r33-r34-skyline-gtr-r32-gts4-right-front-axle-3910023u60 and here https://www.nissanparts.cc/oem-parts/nismo-shaft-ft-drive-3910023u60 Just a little confused because the JapSpeed listing for the GSP front driver axle doesn't mention any specific years or anything and it fit my S1 Stagea fine. So will 39100-23U60 fit my S1 Stagea even though technically it says '11.1999' and up? What would have changed? Thanks.

      CD009 RB Conversion

      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

      R32 GTST - 600KW+ RB28/CD009 Build

      By TurboTapin · Posted

      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.
