No, rods are same length, 25-26-30 all have interchangable rods, 26 rods are stronger , extra 70cc and the pistons have a 2mm lower comp height and are lighter Edit; Sorry, its 1.5mm, the 30 is 2mm

Right, smaller base circle means lobe doesn't extend out as far, I have always believed 9.5 and in my experience with 26 is what I have found but very recently someone I know tried Poncams with 9.15 lift and they fouled I have Type R poncams in my RB2630 and made 460kw @28psi at all 4 and ran 10.8 in a full weight R34 (1661kg + 105kg for my fat arse ) with 24psi, but I don't rev past 7200rpm cause that's where the cams end and the rear housing become a restriction Tomei make a 260 x 10.25 with a 30mm base which would just clear but IMO its too much duration for the lift, 30mm is the diameter so 2mm less base give 1mm more clearance

Contact Unigroup Engineering, they have a set of 260 x 10.8 cams that are stock 32mm base that use the factory buckets and only require shimming, have you had the head relieved for high lift cams ? Don't fark around with a replacement gears set, just get a sequential, you'll be glad you did in the long run and will make car faster

I depends how you split your moneys, i see it as tyres are a consumable like fuel and rego though if your going through tyres at the same rate as fuel you've got an issue Engines aren't much different to tyres, especially if you own a RB26

That's a big bump, on 10psi boost with E85 I'd be ok at 10.5 but a lot happier at 10, I've got 9.5 now and am jamming 28psi into it

What he said

Super tech springs are fine at that, IIRC they are happy till just after 11mm Tomei Procams have a 30mm base circle so the buckets they say you need to run have 1mm added to the top of them making them thicker where the lobe hits so you don't have to run to thick of a shim

This, I'm bored and could use a good laugh It's on E85 yeah, then don't worry about it and just bump up the C/R

10k isn't a hard ask providing everything is up to the task, as for cams, get a set of Tomei 280 x 11.5mm super highs, will give you the velocity to run those RPMs as well as the volume to make a puck load of power while your up there, this cams will be a pig down low for general driving and make the turbo lazy between gears so better suited to auto application The 260 x 10.8mm will go to 10k but that would be the end if there range, they will make the car better lower in the rev range and between gears and still good power for most of the rev range I remember one of your threads now, I believe it started with " I'm a street racer " or something to that effect and which point I moved on and so would a lot of the people on here who know something as street racing over here is very much frowned on and anyone that would get on a open forum stating that must be a dumb arse

Um I think I still have one maybe, but might have thrown it at the start of the year, will look tomorrow and get back to you

That is a descant looking 34, but the photo is just insane and frame worthy Looking forward to see more pics

Depends what your after Have a look in the texi wrap thread for a better pic of it

I'm in St Clair I also have a ratty looking black 32 GTR with white wheels, but no pic in my phone

Lift is volume, duration is overlap, both have different effects on engine and turbo charistics Manual or auto ? Capacity ? Turbo? Do you have a thread of your own ?

Mine was a fresh untouched 86mm, I went 86.5mm and decked the block to 0 deck height Piston clearance is up to the manufacture recommendation, no deers eyes what mine is set to Doing a comp test might give you an idea of the dynamic comp ratio but the static ratio has the be measured and calculated

I have Wiseco RB25 pistons in a 30 block with a 26 head at 9.53:1 static comp ( +/- 170psi ) and have pumped 28psi into it on E80 before the rear housing choked it, going to change turbos later this year and keep pumping boost into it Go for 9.5:1 if you plan on E85

Don't use the original boost solenoid hoses, it won't work properly, they have to be bypassed

169kws, that's mental, congrats mate Slicks - strip - post results And some more pics

I have just picked up a near new Navara LSD rear diff centre and am wondering if anyone knows if it will fit into the R32 GTR skyline diff housing ? It's a 31 spline r200 clutch type LSD centre

Serving trays under the back wheels with hand brake on works way better

Front LSD is a good mod to do while its apart

What car, I'm gonna guess GTS-t, in the GTR that thing you removed on the intake side is a divertor block that changes from the HICAS to the cooler, if you loop those two pipes it should just run through the cooler, that said that might be different to the GTR

It's money best spent else where, unless your one of those people that want your car to just sound good and feel fast

Weldon do a 6 micron fibreglass E85 safe filter, I have a 10 micron Speedflow steel screen filter in my system, the problem with most filters is the "glue" that holds the element to the housing gets melted from the ethanol, I did find a few that would be ok before I decided to just get the Speedflow one

Did it have an extended oil pump drive fitted ?
