Fox, Frink and I will be working on the vids on Friday... We might chop up some small ones and post them here but thats really up to FoX not me, hes the one with all the cool software.

Footage is really good we watched it yesterday, should be a great DVD

im debating whether or not to put the dyno day on one DVD then another event on another DVD, or if we should cram it all together on one DVD? maybe we'll do both.

we need to get shirts made up that say SAU Film Crew, or SAU Media. he he

  • 2 months later...

And now to dig up an old thread.....

Mick (R31DET), Luke (Frink) and I have been working on the video footage, and as I promised Jayce earlier tonight at trivia, here is a snippet from it.

It's a section from the very beginning of the film, Leech's first power run (not giving away the result for those that don't know what it was).

We're going to continue on it until it's done, hopefully shouldn't be too much longer.

Sorry about the wait so far.

YOU DA MAN Mark, Mick and luke. And looking at that video that seems to indicate that my car is not capped to the 180km going off the fact that it was well over the top of my speedo... interesting very interesting superfly i can race you guys now hehe

Good point, someones either cut the wire or aftermarket/chipped ecu. Pull the passanger footwell kickpanel off and see if theres a pretty sticker on it.

Given that the car is supposed to be a stock series 2 R33, the lack of a speed limiter (and rev limiter?), and most importantly the power output that it produced, especially on it's second run, I'd quite confidently lean towards the idea that the ECU has been tinkered with somewhat

hmm interesting we pulled off the kick panel to rig up the wire for the afr gauge and it looked stock to me. Maybe i might have to have another look at it ??? off the top of your head do you know which wire i should be looking for that is the speed limit cut off. Also mark the rev limiter is still in place as it hits the cut at i think at either 7,500rpm - 8000rpm but woot as i said i had never taken it above 170 so to see it do that is a good sign that

it can cope with a bit more boost, getting to the rev limiter and by the looks of it around 200 - 205km's

so to see it do that is a good sign that it can cope with a bit more boost

I wouldnt be too confident on that. Most jap 'fiddled' ecu's are fine for stock boost levels on our shitty fuel, but they crank massive amounts of ignition timing into them for standard boost (which in turn, makes them more responsive and make lots of power). As soon as you wind the boost up, added with the way-to-advanced ignition timing, you'll end up with a dead engine. Or at least thats how it works with alot of aftermarket GTR computers. Before winding boost up id get it on a dyno to have AFR's and ignition timing checked, and make sure the tuner has det ears on to hear if theres any unwanted gremlins in the engine (aka detonation).

I was pretty sure RB25 standard rev limit was 6900rpm? I know RB26 is 8250rpm and the 25 is a good 1000rpm lower than that. Id definately be saying aftermarket computer, but it doesnt make sense with the rest of your car being stock standard... wire #53 is the speed cut wire. Pull the kick panel off, unplug the loom and take the computer out. I wouldnt be suprised to see a pretty Mines sticker or similar on the back of it.

interesting... maybe i am way off or something i dont have the car on me today but when i get home i might do some investigation. also maybe you are right about the rev limiter in terms of being limited to 6900 - 7000rpm personally i still think my car has the stock ecu but i guess we will wait and see.

also in regards to me getting the air/fuel rations checked already had that done on the last dyno run was around 10.5:1 i think it was which was WAYYYYYYYYYYYYYYYY to rich.

ewen do you have your car here today let me go have a look at the tacho :)

Definately starting to sound like a chipped ECU. Thats what the japs do, advance ignition timing like crazy and make the car run overly rich so it doesnt detonate. Keep in mind though, they use 100RON fuel, we use 98RON. No 180 speed cut definately means speed wire has been cut or the ECU has been modified.

    • Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in? 
    • @Duncan I can try  and thanks i did not thought about VIN and part numbers for 33/34. @GTSBoy yeah it looks like iam gonna do that  
    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
