Hello i would like to know the HP diference between a 63 and 82 ar gt35r, with stock cams, i was told by a couple of well known engine builders, that the diference on a stock camed engine particularly wit the gt35r that the diference up top would be around 15 whp. has any 1 had any direct experiance with something like this, 1 of my engine builder buddies dyno'd 540 rwhp on a clients rb25, greddy intake manifold q45 throttle body, with a ported head, at 24 psi with a gt35 ar .63 ar housing and an AEM ecu

you shouldnt be worrying about power with exhaust housing to much. thats for the actual turbo size itsself mianly.

exhaust housings should be used to determine how agressive you want your car.

someone posted on here before saying he didnt hit full boost until 5000rpm using a 1.06. which is just a lil to late.

if your still running the 2.5 engine with no cams. stick with .63 or a .86

but to answer your question, i have no idea sorry.

Im running the .63 rear version, although I have poncams but the rest is the same (Q45 etc) ... havent had the final tune yet but 306rwkw on 16 psi atm (quick tune after engine was run in)... 25psi roughly being the end target... My tuner reckons the rear will max out around the 340ish mark.. Il know by the weekend :blink:

He was impressed at the response though, and said it wouldn't be worth the extra kw at the top end to sacrifice the response I currently have. Although I do have the .82 rear on standby... :P

400rwkw (540rwhp) from a .63 housing and 24psi seems just a little unbelieveable to me.

The .63 limits the GT35 to around 600hp, and it would be so severely choked.

hrm... The .82 (depending on comp wheel) is rated to 700hp i thought? And the 1.06 was the same, just for larger capacity motors so they arent too restricted.

If you have a .63, it'd be getting a turbo from the smaller family, GT3071, GT3076 etc.

.82 for the GT35 or 1.06.

Thats just my choice having had a 600hp GT30/.82, show was on approx 4200rpm (stock RB25 head) really linear but a 550hp/.63 probably better :)

hahaha thats the biggest load of crap i have heard all year 400rwkw from a .63 housing..lol in your dreams!

the max youll get 340-360 and thats running more than 24psi.. on 1.5bar i was getting 330-340rwkw and it was running a little rich...

      Seemed to be good when Jeff owned it but they did a shit job on my car, probably worth a think before spending 10's of thousands of dollars where they might be cutting corners

      DeAgostini 1/8 scale BNR32 Nissan Skyline GT-R Nismo

      By Rezz · Posted

      Starting with issues 1 - 5, we have already run into a problem...!  Issue #4 contained 2x front brake calipers, instead of 1 caliper and 1x steering knuckle. Will have to call DeAgostini on Monday to sort it out. Anyway here's some photos.  Issue #1 is the front bumper, headlights and number plate. Issue #2 is the front wheel (with "We produced with spartan air." text on the centre cap!) and tyre, the front lip spoiler and cylinder head cover with ignition coils under the centre cover... which will never be seen again. Issue #3 is the bonnet and cylinder head. Issue #4 is the front strut, brake disc (with laser etched metal discs) and brake caliper. I stopped here because of the issue with the missing steering knuckle.  Next update will be #5 - #10 in a few weeks.

      DeAgostini 1/8 scale BNR32 Nissan Skyline GT-R Nismo

      By Rezz · Posted

      DeAgostini is one of a few companies that release quite large (the largest commonly available size actually) 1/8 scale models in a series of weekly issues over 100 - 110 instalments.  They release different models for different markets and DeAgostini Japan have release the BNR32 Skyline GT-R Nismo last month. I've made two of these 1/8 scale sized cars (one an R35 GT-R from 2012 - 2014, the other I'm just about halfway through, a BNR34 Skyline GT-R from the 2Fast 2Furious movie) so when this R32 was announced there was no way I could ignore it as it's my favourite out of all Nissans.  Each issue costs around $20 so it costs about $2.2K when completed. I suppose it is very expensive for what it is, but the quality and details are really very good, and there are many "gimmicks" like fully functioning exterior and interior lights operated with a remote control, working steering, all doors/bonnet/boot/fuel lid open and close, the side mirrors fold in and it even has a speaker for the engine revving sounds when you turn the lights on.  Each issue comes with a magazine that tells the story of the BNR32 Skyline GT-R Nismo from the first design stages of the BNR32 to Group A homologation and the various racing version that were run in the Japanese Group A and JGTC, and Australian Group A.  So I plan to update the build in this thread 5 issues at a time.  https://deagostini.jp/r32/?srsltid=AfmBOooKjxDc4EUK2rmXqMBPgyHfFJ24s4oEPJBNpnF-lFlsRoW0PE6P
