But if you are planning on sticking with the std turbo....i would be very interested to see an engine that actually has more mid out of it. Does anyon ehave graphs of before and after?

Even with NickR33s results...im not convinced. The std turbo isnt that big for a 2.5L and i doubt they can provide the airflow to really need cams to help fill the lungs.

If NickR33 picked up some grunt...i woudl then ask did he have the SAFC tuned before the cams were installed?

Not being argumentative, just curious to see if we can rule out some other things :P

I used to have a before and after graph, it was about 15-20hp up in the mid range. The top end was improved also but, without access to the timing maps (S-AFC II) the top end had to be left alone.

I picked the HKS exhaust cam as it was spec wise pretty close to some advice I got from someone in the cam making game.

Ok, thats interesting then. I know of a few examples that did nothing with cams. One i read about and another was a friends R34GTT which actually lost power with the std turbo. It wasnt until he got the high flow goign that it shined.

Perhaps there is more to it, i stand corrected :P

No Roy,

You are right about over-caming the motor ,the main issue is going over the top on the inlet side with such a small turbo. The R34 Neo motors have a better profile set of solid cams than the hydro- R33 ones.

I used step 1 HKS 264deg 9mm lift exhaust cam and the factory inlet.

Hey,

Cams are good, especially poncams which do not need heavier spring, valves, or having an aftermarket computer in.The Poncams are designed to bolt on and drive off...not even cam gears are needed.0 adjustment works the best for them.

If this is the only modification you are planning in the next year or so ...do it because you will get great results.

Hope I have been of some help..

Cheers :P

These cams are around $800 for the set and installation should be around $400.

Your power output will increase slightly, but your response and power curve will be alot better.

Where do you get poncams for $800?

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
