Hi all,

i currently have a Blitz Nur Spec 3" Cat back system on my car (Cat is standard), and im am thinking of going from the turbo back but i need a bit of guidence.

First of all, i read about split dump pipes and one piece front pipes, but that has just made things more confusing and difficult to make a decision. my main aim is to basically decrease lag.

What do you all recommend?

The car is pretty loud as it is with the cat back system, will it get louder if its a full system?

Im also after a hi flow cat, i hear catco is the best, do you agree?

Should i keep it all the same brand, if not which should i go for?

Anyway, please post your opinions.

Thanks.

OK I'm going to jump in before everyone else crucifies you for not doing a search first....

Just go out and buy a BATMBL split dump and front pipe in one (dont get stainless its a waste).

And whilst you are there buy one of his metal cats.

You wont be disappointed. THis is the route I'll be going when I have the cash.

Do a search for the thread, its in the business traders section, with dyno results etc...

As said above: Go with Michael's (BATMBL) split dump and front combined pipe in the Business Traders section. They are well designed and pre heat coated in mild steel. Definately choose the split/seperated dump if you want to reduce lag.

Regarding the cats, if you have the money definately go for the Metal Cats or the 5" body metal insert Catco cats. Otherwise get a 3" hiflow cat from Xforce for around $160 delivered - this is what I'm doing as I'm only aiming for around 200rwkw.

Noise mainly depends on your cat-back system. If you would like a quiet exhaust I'd advise adding a mid-muffler (box type) between the cat and rear muffler. Most quiet exhaust bolt on systems (Trust PEII, Fujitsubo Legalis R etc.) have a rear muffler and mid-muffler.

When I had my cat-back only on the GTIR the only increase in noise I noticed after adding a dump/front is that it was slightly more lower pitched, not quite more loud in volume. If you knwo what I mean.

    • Pressure when IDLING, is meant to be 51PSi... So that amperage value needs to go up a fair chunk... I'd personally be factoring for more like 12amp at least on those runs, and at that point you need to hope the already there wiring doesn't drop you a volt or two, as that's a lot of fuel pressure flow drop off from 13.5 to 12V! Taking idle pressure of 51psi, means the pump will be drawing a MINIMUM of 9amps all the time based on your reading of the graph (3bar base, then allowing an extra 0.5bar for boost = roughly 51psi)
    • Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D    
    • Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D  
    • Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.
    • Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
