Nice vid, the photobucket clip is really good quality already? Sounds tough as and hauls ass...what light came on on the dash? ATTESA/4WD?

Did you retune with new manifolds???

I think photbucket took a while to process it, better but still not HD like the oringinal. Yeah the Attessa faulted so had to reset. Definately needs a retune with these manifolds.

I have confirmed since my track day the rear manifold at least has warped 7mm, so my inlet pipe now rubs on the strut tower. I have to pull the motor to check as it has developed a slight tick. I will be weldings some support brakets onto these manifolds from the flange to collector.

Something I would be doing from the factory on these manifolds from now on.. Or before you install them

Hope the tick is nothing major. Really now seems alittle too much effort for a little gain. If the manifolds warped surely you would have to bin it?

Yes lots of effort, however the gain is not little. My injectors are maxed at .35bar less boost....prob why I have a tick now :whistling: Slightly down on compression on number 4, oil dripped in brought it up 125 to 140 psi, all other cylinders are 150. So the motor is coming out no question. All good though, there are a few things I can tidy up and replace while I'm at it. I'm quite happy with the performance now. Reliability is the goldern aim for me. My goal is to find out if it was pinging or an oil control issue. I run an extended trust gated baffle and extended sump(6L) Will pull it out over the next few days.

7mm warp?????

I wouldnt be happy at all...for the price and considering theyre made from freaking steam pipe thats definitely not a good thing.

Imagine having to pay to get them installed only to have them warp and create other dramas.

Did you install the factory bracing brackets that bolt to the bottom of the turbo dumps to the block? Im assuming they didnt fit but did you made up new ones?

I was considering these but now I think im well put off by the warpage factor.

I guess factory manifolds really are the best thing.

The factory brackets didnt fit the Tomei dumps.Possibly could modify them--> which is not a bad idea. Even the factory manifolds droop...hence why Gibson team installed support brackets. Might have something to do with pressure from our side pipes...

Flow tested the factory manifolds against the chinese stainless and they flowed 50% less, 6hrs of porting the OEM and got them within 15% of the stainless.

I would use these 6boost mani's on all my future builds, no question...I know whats required for install now.

Have you been in touch with Kyle throughout the install? Im sure he'd be interested to hear about the issues youve had...one of the most helpful, genuine guys within the modified car scene and so much knowledge...

Not knocking you but suprised you didnt have a look at the tune before you took it the track and gave it a hard time?

      Returning after a long time!

      By Shizu · Posted

      I havent bought a manual cover for the dash yet and no cluster change, won't bother me too much, I just need to get that auto box gone, manual in! I miss my manual. 🤪. We started last weekend and managed to get the box out. Planning to start putting it in this weekend and then order a single piece tail. We were super careful to take time and not damage anything. It's my first time working under the car.  With my S15 mainly worked in the bay. This time, it was a headache because of three or four bolts only. They simply didnt want to leave thei homr and the one securing the tailshaft, another above the GB, and the one securing the lipstick was a shit. Mates mate, Davo caught fire 🤣, nearly opened his chest up with a grinder 🤦🏽‍♂️ and both mates nearly had a plate from the box land and slit their head open. Fun times. We all survived. Not the easiest working with limited access on jackstands. As I'm sure we can agree these are the memories which make us love our car. For all three of us, was an awesome weekend and Sunday 3.30am before tools down was a fantastic effort. I need to upload pics, but looks like it needs to be via Url now. We used to be able to just upload pics back in the day. It's been that long! 🤪 Im currently spraying rustoleum under body, not because it's rusted. It's super clean, but just so it's protected for the next 10 years. There was a few surface rust spots. Which pretty much wiped off with a 3M scourer.  Really impressed with how well the previous owner maintained it. Bank account went down so quick! Service, then GB - managed to get a spanking new 34 genuine box from Nissan. All the rest of the conversion parts from Kudos.  Went with a Nismo short shifter. New pedals and Exedy Clutch and FW. Ordered the Prp Rear Main Retainer kit which should arrive Friday and my first engine mod part just like I did with my S15 will be the Tomei Expreme Turbo Outlet. Already on order. It'll likely sleep next to me on a pillow during the coming months. 🥰 Last build was on my JET200GT profile and on SAU and Hardtuned I had documented the build. Planning to try to do that again. Brands feel scarce now. Wish we still had ARC and Apexi parts readily available. Exhaust - need some advice on this. I had an Apexi exhaust on the S15 and loved the tone. My mate had a HKS HP Silent on his 33 and suggested I go with that to avoid drone. I can't remember hearing an RB25DET running that so will likely need to wait for a meet or something to hear it.  Not after big power, just enjoy building it, and drivability with minimal negative attention.
