Hi guys,

I've been slowly buying parts to upgrade my car

I've got turbo (HKS GT2535), intercooler (Cooling Pro Stealth Series for R34), front pipe (JJR Bellmouth)

Is a cat from a R33/R34 bolt straight on? I'm looking at a magnaflow 3inch cat that has been flanged already and want to that it will bolt straight on

I'm going to custom the cat back (don't want a cannon tip and can't find what I want around)

the last bit is the suspension - this is proving to be a nightmare...I don't know that the group buy is still going...if it's not going - that what options should I go for (don't want coilovers - too much hassles and I have read the suspension thread and made even more confused :D )

Yes, 34 and 33 cats use same flange pattern, bolt on.

Have you considered one of these ? Mine came with the flanges, bolted straight on, very happy with it.

I fitted a JJ Bellmouth and Hi Flow X Force Cat. Fitted perfectly on my S1, with a 3" Cat back, as supplied

Increase in power most noticeable and saving about 2l/100 in fuel.

yeah I would love to get a metalcat but there are none around and I have spoken to some exhaust places around my place there is a massive back order for these...they recommended me to go mangaflow (that's my second choice) or to wait (which I can't)

If I can find a metalcat that I can get straight away then i'll buy one

just get the x force metal cat. cheap and good. be sure to get the high flow one its worth it.

Thats the one I got from JJ. Also put in a new O2 sensor at the same time.

I just came op the mountain and the difference with the X Force and bellmouth is amazing.

Before it was like 3 grand plus and 4-5 psi to keep at 60kph, now it comes up at 2and a bit with no boost, so in effect the S1 now comes up in D and not 2nd, hence the better fuel consumption.

Also fitted a hi flow panel filter caus I have a cold air deflector.

I have had a HKS 2535 on an R33 and I tried 3 different exhaust combinations and let me tell you the 2535 is a great punchy turbo but it really needs to breath!!!

If you can gut the cat and you will never look back, it really does make a massive difference.

It also makes your rear bar turn black from the carbon deposits your exhaust puts out too. But who cares when you've got a Stagea that blows flames? :/

Well I got a magnaflow cat. got it for $280. Now just gotta go to the exhaust place and get the cat-back made up. Xmetal - the reason I didn't get a X-Force 5 of my friends had their one collapse on them after 6 months.

I'm going to go custom as I don't like cannon exhasuts (personal choice) and can't find a aftermarket dual tip exhaust (or maybe I haven't looked hard enough).

I was thinking to go for a de-cat...but i guess i want to go for a sleeper look

      M35 Brake caliper replacement

      By Waders360 · Posted

      Hi from Canada, Both of my calipers are starting to fail. My car is a 2005 M35 Stagea ARX and I can't seem to find any parts or any cross reference caliper that would fit my car. Is there a company or a similar caliper that would fit and I could replace the OEM one. Or if anyone knows where I can find a new OEM. Any help is very appreciated. Let me know!

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.
