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

      S1 rb25/s14 starting problem

      When you crank your car, and hit it with a timing light, can you see a steady crank timing?

      Oh, forgot to add, A few months ago I was getting mixture codes and the car was using crap loads of fuel. You could smell the unburned fuel in the exhaust, it was crazy strong. Economy was over 17.5 l/100 and usually around 19. I smoked the engine and found a leaky CCV hose which I replaced and then I replaced my two pre cat O2 sensors, I also replaced the MAF. This fixed my mixture codes and improved my exonomy but I'm still 14 - 15 l/100 when pottering about town so something is still amiss. Throttle response is much better and it has more pep but I'd like to know why it's still so thirsty (and I'm hoping that whatever it is gives me a bit more poke).

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Hello all, currently finishing up a rb25 swap into my s14. Having issues with starting, car has spark (confirmed by pulling a plug and watching it spark), has fuel(confirmed by checking pulse/voltage at injectors all spark plugs are soaked in fuel). Car cranks over and pops into the exhaust with a heavy fuel smell but no attempt to start or run, I have torn the timing cover off and triple confirmed timing, turned the CAS in multiple spots both directions, attempted to start with coolant temp and maf unplugged, checked my fuel lines and made sure they weren’t backwards, checked voltage at cas/injectors/coilpacks, made sure all the grounds in the harness are connected and added a few grounding straps (1 from chassis to block, 1 from chassis to head, and 1 from chassis to igniter chip) I am getting stumped here. As a last ditch effort I made a full grounding harness tonight that’s going to run from the battery and add an extra ground from the battery onto the coil pack harness/igniter chip/ intake manifold/ Wiring specialties harness ground/ and alternator. I’m hoping maybe the grounding harness will fix it here but posting here to see if anyone has any other ideas on what else I can check. My fuel pressure is unknown right gauge will be here tomorrow.  IMG_3206.mov

      yeah I was shocked when I checked my spare OEM on and as below that's how they come from Nissan. (side interesting note new NEO gearbox and replacement park lack the brass bush on the tips and its just all alloy) unsure about damage to the box currently back at 1110 to be pulled down/inspected and selector fork replaced as he built it previously and given the never before seen failure on his billet forks he is replacing it under warranty. He said he has used always OEM the keyway tab without issue for years so it could be an unlucky coincidence. I did talk to him about the sharp corners and stress concentration too. Re: hard shifts i got 7+ years out of the OEM one and the fork itself failed not the keyway. so could be bad luck as I said or an age thing + heat cycles in box and during fabrication of billet?
