hmmm, depends what "hi-flowed" means to them. What they can do is cut a hole in the top of it, rip everything out of it, and weld the top back on. In which case there should be a patch of weld around the top of it, Which means you wont be able to see it unless you take it off.

dude, i jus got my r32 complied and registered and can tell u for a fact that compliance ppl are dodgy as! They (usually) put the cheapest cat they can get so their costs are down. i made the mistake of not keeping the old 1 they pulled out, as a result i have had a noticable drop on power! Unless u kno the guy doin the job and u can trust them den its ok. Doesn't really answer ur question but anywayz......

i didnt know that a high flow cat made much difference over a stadard cat? though you can pick a decent 3.5" one for about 250-300 bucks depending on where you go. the standard cat is hell small though. do take note that its illegal to not have a cat coverter.

Well the compliance guys said that they need to change the cat anyway for compliancing and that for an extra $100 i can get a hi-flow one.. but i just had a look... the actual cat isnt that much bigger than the exhaust pipe.. i'm not sure if my exhaust is 3in or 3.5in.. it looks pretty big though....

      Wanted to buy R200 longnose LSD 3.9 ratio

      By Ben_D · Posted

      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

      Back for more after 18 years - and where are the longnose R200 LSDs?

      By Ben_D · Posted

      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

      G35 Control arm and Compression Rods into a V35 Skyline.

      By sonicii · Posted

      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.

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      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.

      Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)
