while you change the cams do the retaining bolts for the cams. They have a habit of breaking as they cop a fair bit of fatigue when being torqued off and on. Tomei make some beefy ones. Also worth having a look at the valve springs etc. depending on what rpm etc you are going to see often and which cams you went for in terms of lift.

PONCAMS 260 in and ex ..9.15 Lift...TYPE B 143005 .

Can not find Tomie Bolts.

Was told to keep the standard lifters.

Thanks.

Hope I am not High-Jacking this thread :happy::P

no, keep going. this is the most constructive thread i've started, even nismoid didn't flame me

has anyone else heard of reducing exhaust runner diameter to increase air speed to increase response?

p.s run out of money for cams, so standard ones will have to do. what cam timing specs do people recomend? i'm tunning it next weekend, i'll keep you posted with the results.

2 deg advanced on the intake cam and 4 deg retarded on the exhaust cam , for stock units this is generally the starting point. Mind you thats for stock turbos airflow.Use it as a starting point since you may find a slight adjustment either way might give better results given the airflow on the 300rwkw turbo you have.

Ye, every car is different, some like a degree here or there over others.

Its really something you need to play with on the dyno to see what will work best.

    • Hey all, not sure how active SAU is anymore but will ask away anyways. Just wanted to get some experience on the 2008 model GTR CBA model.  I've hit that age in my life (43) where I'm like fk it time to get my dream (midlife crisis) car. Looking at importing one in and seeing if these can be reliable if the main flaws are fixed up. Plan is to keep money aside to do the following straight off the bat to future proof it: * install a stage 1 rebuilt trans with all new bits and pieces.  * install a new Bellhousing from the later model GTRs. Or potentially an upgraded stronger version like MAD or ATR. Besides the above two things and typical maintenance items anything else you'd recommend doing.   Been speaking to a few people and the engine on these are very reliable apparently. But keen on the view of the community here. Hoping to find a nice grade 4.5 with low mileage in Grey. I'd go black but swirls too easy. Look forward to your responses and feedback. Cheers    
    • Do Alan and Keith work on Skylines now? I remember buying stuff from them when I owned my Ralliart Lancer a few moons ago. Definitely genuine guys and be excellent if they dealt with the skyline platform as well.
    • Hey all, I'm Gaston from Sydney's West.  I was a member on here when I was a younger lad and owned a mint R33 GTS-T. Ended up selling it and getting married having kids (yadda yadda) we all know how the story goes. Now I'm back with the intention to get my midlife crisis (dream) car ... a R35 GTR.  You'll see me about asking questions and searching the forums. Good to be back and can't wait to get back an Import again.
    • I have to put something here in order to post the photos. From what I could gather there's more enthusiasm for modified cars now than there has been for years. There were probably more younger people there than older (me included lol) which was a good sign.  It did seem like the record least amount of representation of the 90's era hero cars on display though. Like maybe one or two examples of S-chassis Nissans, and maybe 3 or 4 R-chassis. By comparison there were a lot of Civics from that era but in all there were about 10 - 12 EG/EK Civic Type R.  Euro exotics are always there in large numbers, led by Liberty Walk...... say what you will about kids using markers to scribble on a Ferrari F40, it did seem like a stunt to infuriate Ferrari enthusiasts, or Ferrari itself. I wonder if there's something more to it. Either way LBWK have done some heinous things to a Lamborghini Miura this time. They should stop now.
    • Engines and drivelines are not war stoppers for me mate, busted arse bodies and un-obtainium parts and panels are though Both cheap Brumbies I looked at had trashed tubs and a fair bit of rust
