coolers do not cause lag, i dont know where this idea comes from. as for pressure drop, this is needed as the inteference in air flow thruogh the core is what dissipates the heat out of your air charge. if your cooler flows with no pressure drop, its not efficient. you should defenetly feel performance increase with a good quality cooler fitted because your air charge is denser. this is what coolers are for.

if yor not feeling it, your coolers not efficient. you have just extended your cooler piping. factory cooler probably more efficient at lower boost levels. you will definately sort the good from the rubbish when you start pushing some boost.

10psi isnt worth the effort. you will notice the difference at around 15-18psi

The reason ppl equate big ICs with lag is it will always take longer for a pump (in this case turbo) to pressurise a larger volume given the same flow)

So the turbo has to pressurise the pipes, the intercooler and the inlet manifold before it has a hope of pressuring the combustion chamber. Obviously a good coolers ability to flow air is important, but ppls fear of not seeing boost as quickly is based on the change of internal volume to the system when running the std turbo which can only flow so much cfm.

Yeh, yeh someone is going to come along and say boost is irrelevant, its cfm that matters, boost is a measure of resistance la, la, la...but we are all on the same page, generically more psi - more cfm

haha lol at above!

So far ive gathered from here that Hyperflow have the best coolers on the market. Also that ARC have the best coolers on the market. Can anyone tell me more about these hyperflow jobs?

Ive been running a older hybrid, 600x300x75 thru various stages of power, now making ~270rwkw at just under 1.2bar. No probs so far... Id consider getting something phatter coz its the only thing that i havent upgraded for a while, but theres no more room without hacking into the bar.

no dyno graphs, but i have owned 2 gtsts, one with a fmic(now) and one without(my old one) and test driven HEAPS (have made a few friends buy gtsts too and im always the test driver!)

and every one with a fmic felt laggier.

i think i should re-describe what i meant, instead of lag, a better description would be throttle response.

roy, i dont have a huge fmic, i have a greddy smaller model one! (i think the vspl) with greddy piping so nothing out of the ordinary.

good reason to go too custom plenum. Shorter pipes etc, are people really persisting with standard turbo?

did you have to hack the front bar to fit the Hybrid kit Munna?

Your front bar is the same as mine(if thats your car in the sig) I had to cut about 20mm off the bottom lip for it to fit I also had to cut the front bar support. No big deal all fitted up well and looks good now its finished.

I ran 10.5 psi before I had the cooler on and im still running that now I had a big miss after I installed it took it to my tuner and it turns out I had dirty coils they cleaned them, regaped my plugs and retuned my SAFC for a result of 195 at the rears and you could realy fell the differents in performance.

:stupid:

yeah thats my car in sig so we have the same front bar and I have the same cooler kit as you... could you send me some pics of your install? I am also running 10.5psi and have a SAFC so am hoping to push somewhere near 200rwkw with the Hybrid kit... have you upgraded your fuel pump?

did you install it yourself? I am toying with the idea... however I am not the most patient person when it comes to mechanical things...

Did you get fitting instructions with your cooler?

I fitted it with a mate who is a machanic we took out time took most of the day. Fitting instructions should come with the kit you will need to cut a hole for the return pipe but its all in the intructions all the pipes fitted up nicely. Unfortunatly I got no pics while we were installing but I will post one of the finished job when I get a chance. Might be worth getting a quote on fitment if you are not very patient with machanical things.

I have not upgraded my fuel pump although it would probably be a good idea to do so I have had it tested though and it is in good health. All my mods are in sig with the same mods and a good tuner you should get a similar power output.

      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)
