Hi guys. I had my dump pipe upgraded to 3" and they found a crack on my manifold. Does anyone have connections to a new one? Or is welding better for now? Not many stageas around my way. Any help would be appreciated. I heard stainless ones aren't that great. Is that true?

Where are you?

What kind of Stagea you got?

The more info you give the better the help you get :thumbsup:

*EDIT* My bad just read the rest of your thread title :whistling:

you can pick up a 2nd hand manifold for around 50 bucks. they wroth nothing, even if you opt for a low mount from ebay they around 200-300. better than a cracked one.

and the rest depends on how good you are at bolting the thing up.

from what i know any Rb20/25 exhaust manifold should fit.

Hey sorry mate ye it's 1996 stagea with the rb25det. Where are the $50 ones? And is that a stock one? I've looked on eBay but I'm not too sure on them. Are the stainless Ones k? I'd get my mechanic to install it. I haven't got time or tools to do it. I'm in Victoria.

Stainless manifolds (especially cheap ones) are more prone to cracking than the factory standard cast items, so unless you are trying to get every last kW out of your car I'd just try and source a standard one.

I recently cracked and replaced the manifold on my R33, it's a little fiddly but easy enough to do. Just be prepared to have snapped manifold studs drilled out :thumbsup:

Hey my stagea does choke up when I floor it. Abit of lag. Would the small crack be the cause?

Possibly, I picked up a little response when I replaced my manifold. I mean the more exhaust gasses leaking through the manifold, the less exhaust gasses that flow through the turbo to force more air in on the intake side.

That, and I imagine any exhaust gasses that are leaking before the O2 sensor would cause the ECU to not run as well as it possibly can

or if you want to do it a cheap way you can use a normal welder to just weld over that crack...... dont know how long that will hold since its steel weld on a cast iron manifold, but some people have done so and its been ok for years. (would advise against this though)

so i guess my estimate for 50 was a bit over the top eh??? seems like they exist cheaper

      Please use a modern ECU. PowerFC with the Nintendo Gameboy controller is horrible. It's not 2005 anymore.

      ECU sees many times the speed than speedo does (R34 swap)

      The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.

      Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

      The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
