hey Joel.....did you have to retard the exh gear to compensate and bring the power curve back to the left?

I'm abit confused, cause even though 9mm is not huge lift, when I went to school, bigger overlaps always caused a shift in rpm in a northerly direction.......maybe it's more to do with your tune than the cams cause I always thought that better response is not generally a side effect of bigger overlaps :blink:

:laughing-smiley-014: Back and to the left........

ahh ok.......sounds like an Ivan Tighe grind.

I though you may have been running a Poncam, HKS or similar cause they all run bigger overlaps than stockies

Tighe regrind it was.

I stumbled upon a list of HKS, Jun and LCA's but be buggered if I can find it.

I do remember the Rb20det's definitely had the same 110 and 115 LCA's when running in the 264 duration range.

Rb25's.. 115/115.

So would u recommend me get cams if I'm getting camgears, turbos, and injectors (and their support mods, fuel pump, water pump, afm, gaskets)... and if so, what type? I know nada about engine physics

-D

Cams always help make the power easier..

Don't overcam it. I was a little nervous 265's were a little too big but Shaun has had good results with that type of duration on fairly stock rb30det's previously so I went with his advice.

yeah we used to deal with Tighe Eng many years ago when I was still at Adelaide Eng, so I've considered going with one of his grinds as opposed to alot of the Jap stuff out there.

Good thing about them is that they don't just grind a second hand cam then end up with undersize lobes that have gone through the hardening process but instead they either start with a new billett or build up the lobes first. I find that alot of the jap grinds aren't really considering the average Joe that needs to drive to work through peak hour.

Sometimes I wish I still had access to our cam grinder and all the various masters that we had cupboards full of.

    • Initially I thought having a pair of Recaro seats would be a big bonus, it turns out these do get a little uncomfortable on long journeys (my fault, not the seat). I had a look through the GSM Performance website at reclining seats and booked an appointment to visit their show room. I got the Recaro Sportster CS for the R34 from here, was very happy with the service received so of course a re-visit was in order. Unfortunately the two Corbeau seats I had chosen aren't on display but they had 4 other options available. Two seats dug into my back, one dug into my legs and the other was perfect. I also found out that Recaro seats use a larger bolt pattern so some adaption was required. Luckily GSM offer some universal adaptors that should solve this problem. I searched the interwebs for price comparisons and Corbeau themselves were the cheapest at £300 cheaper (for the pair). I asked GSM if they could price match, unfortunately they couldn't. I later received an email saying Corbeau would honour them the same discount, but the purchase was already made. I did however order the brackets from GSM, both arrived on the same day. I started with the passenger side seat, knowing this was going to be a little trial and error. There are 3 mounting holes at the front and 2 at the rear on these JURAN Racing seat rails.  With the adaptor brackets mounted, the allen cap bolts started to push into the seat, NOT GOOD!  The rear mounting holes lined up but there were issues at the front. The holes were 1/2 hole out, so the brackets got a tickle with the drill to modify the holes. The supplied bolts weren't going to be long enough and a spacer was needed to stop the adaptor bars from bending. A local fasteners company supplied be with some nylon spacers and longer bolts (M8x30, although these will be replaced with 35mm long shortly) A before and after I pre-drilled the front bracket before making a start on the driver's seat to save some time. And in no time at all that was in the car too. The all black seats have transformed the interior and these are MUCH more comfortable. The only downside with the new Corbeau seats is I sit a little higher, but I'll happily accept that over discomfort. The Youtube video can be found here: https://www.youtube.com/watch?v=wPyttKPktXA
    • All 3 I guess. The car came with the JASI Aero 4 door Type R Full Kit unpainted so this was one thing at the top of my list to complete then I noticed there were body panels parts for this kit so i picked them up along with some black mesh to fill in the front bumper and front side air vents. car is at a paint and body shop atm completing this work. Next I will be addressing the internal bells and whistles, great summer project I can do with the kids.  full interior removal - ,boys car sound deadening - pads and spray ,boys stereo, sound, lighting - Big 3, GTT or bigger alternator ,kids head lining - dye black add star lighting mod ,daughter. That's it for the next 5-6 months. I have some motor maintenance  work i have to plan out. oil filter relocation, gaskets, mounts. beyond that, mind is starting to turn over if i can use a DET intake plenum, block off turbo ports & pipe in a air intake.      
    • roller coaster of a ride. Alarm system was removed & main harness was repaired where possible. still no fix just random successful starts. moved on to the replacing the ignition switch and relay. well all this troubleshooting & repair has been going on, the car is at a paint and body shop being pushed around. Ive been going down there on odd days after work to get it sorted.
