I ran last weekend at the Symmons Plains 60th annaverary meet. Unfortunately after a good run the engine decided to throw a rod.  I've got the engine out but havn't pulled the sump off yet, I suspect a rod bolt has failed as it had oil pressure when it failed.

Time to build the 2.2

Yeah it was pretty uneventful from the inside.  I assumed i'd melted a piston, but my mates informed me when I got towed back in that there was a loud bang and there was bits all over the track.

The bottom end is stock crank and rods, arp rod bolts and ross pistons.  I've been using those rods since 2011, so they have done alot of work and I think i put the rod bolts in around 2012.

Well at least you have a crank case breather now, we all know RBs love to pressurise the crank case and not allowing oil to drain effectively back into the sump.

Time for a 3.2L 1000hp motor?

I finally got round the pulling the engine down.  The head had barely been marked, so that's a win.

 

The bottom end is quire the mess though.  Pretty sure I found that the broken rod bolt, looks like a clean brake compared to the rest of the mangled mess

YIKES. So where to from here? There was an RB20 NEO on Marketplace just before XMAS. I had to resist being me :)

I was going to go down that path, even have a inlet gasket to make a manifold adaptor.  But Targa rules changed again, so 26 crank and rods and a slight bore to bring to to just under 2.2l.  Swap the RB20 highflow for a Neo highflow

can you have the head machined(skimmed) with the valves still in the motor? 

The head has to be off the engine and cams removed, but yes i've had head skimmed with the valves still in it.

Would be pretty amazing to do it with the head on the engine 👍

lol would have better luck fitting a golf ball through a garden hose, ended up striping the whole head and porting it anyway so she will be bare at the machine shop. good to know for future tho so dont have to remove the head components everytime. thanks mates

    • Hello everyone. I've recently started the research into R34 GTR front bits and running into eye watering prices. On the plus site it looks like some places make 'replacement' fender liners for these cars. At eye-watering-but-less than stock prices. I also noticed there's plenty of diffuser options available too. What I would like to know is if my following assumptions are correct. 1) The OEM guard liners are actually only 'half' the liner. They go together with the OEM brake vents which are a separate item which looks to be quite a large 'panel' that is part of the liner. The GTR bumper has bolt holes along the front. I assume the ones in the vent correspond to the ones the OEM liner does not have (circled?)   2) The V-Spec front diffuser supplants the brake ducts in the above item. I am assuming these still work with the guard liners as there's no alternate part that I'm aware of. I don't see how they go together, so I'm making the assumption that they have to, somehow. I know the center splash guard is different on the V-Spec (and is the price of the damn diffuser alone). How does the liner interact with this? 3) There's alternate front diffusers that do away with it all. Annoyingly, a lot of the clones and CF different ones... have no brake ducts on them. I like the idea of them though. My brakes get hot on the track. These alternate diffusers are a lot cheaper than plastic splash guards. I'm assuming you don't have to/aren't supposed to remove guard liners to run a diffuser. I suspect that quite a few people actually do not run the guard liner because with a front undertray you're getting a lot of 'splash' guarding anyway, and most people remove liners given they're probably running a pretty aggressive setup with a diffuser at the front. It would also be nice to know if anyone has ever run the 'reproduction' guard liners and know whether the fitment is OEM quality or "OEM Quality". Example: https://www.ebay.com.au/itm/356254671561 https://carbonetics.net/products/nissan-skyline-r34-gtr-plastic-front-wheel-arch-set Is this knowledge still around?
    • Really, effort is pretty low. You hand fistfuls of cash over to someone else and pick it up when done...   And at least this shitbox isn't drinking coolant right?  
    • And most chargers that most DIY people own would put bugger all power back into the battery between cylinders. I've always done it with jumper packs/second battery connected. And that's on any car.   Because race car, and wanting the lightness.  At least in an R33, putting a bigger battery in can at least help shift the weight balance backwards  
    • OR, Tell the Motec to STFU, you said shift, so try shifting! But then yes, I agree, more sensors needed to. Put either a wheel speed sensor, or a diff speed sensor on it. Then get an input shaft speed sensor too. (I say input shaft speed, and not engine RPM). This way, you can now also log and see if the clutch is slipping (RPM, vs input shaft speed), and you can calculate gear (Input shaft speed / Output shaft speed). At least then if the gear position sensor fails you have a backup. And realistically, the Motec should only worry about what gear you're in for the parts where I'm assuming you have some power management strategies in it for the lower gears. (IE, lower boost, maybe different throttle curves, different ignition curves, etc etc). But it should stop it shifting. Pull the flappy, that f**ker should just attempt the motion! Heck, even on a sequential like on a motorbike, you can keep trying to kick it up a gear all you want, the physically part of the box takes care of not being able to loop the whole way around the box! Only part you'd have to worry is how it gets to reverse.  But that's on the driver... An R32 shouldn't be so smart as to try and override the driver on a gear shift  
    • Yeah, nah. Anyone not putting the absolutely largest battery that will physically fit (ie, NS70 X) is not thinking straight. the NS70 X is close on double the capacity of the "stock" unit.
