Mate your cars set up just keeps getting better and better, sounds like you've thought it out well, Hopefully we'll see more then just 2 Skylines in the HPI RWD 2400cc and over Street Drag Challenge soon :D it would be very nice to see 4 of us in there :P

Buster, There are a few cars in Perth already that would make the lists but they don't seem interested in sending there results in. If I get a decent time then I hope to make the list:D

I have a very distinct plan on what modifications I want to make, unfortuately I'm restricted by budget at the moment:(

Would you mind telling me what the other cars are and some details please, are they on the forum? I'm mainly interested in the 60ft, mph and ET as it amazes me what our cars are capable of with the RB25 and not 3L bot ends or RB26 transplants

We don't have that many really fast GTSTs that go to the drags here, high 11's low 12's is about the best of them on street tyres

Can't remember the figures off the top of my head, but I know Got Boost is taking his R32 GTS-t powered by an RB26 down, He's already run a few 12's on snow tyres on a crap track. He'll be taking his Nitto's down on the fully prepped track and hoping for a low 12 or high 11:D

Most of the RB25 powered cars are just starting to move into the 350rwhp area, so we should start to see some good times coming out soon:D I hope to be one of them:D

Hi Steve- SST and GTS-t VSPEC, com'on lets start an ECU debate, you guys reckon I am wrong and don't know what I am talking about. I'm ready to prove otherwise.........

Oh why are you getting a 2 way diff, when drags only go one way?

Sydneykid, I may be way off line here hehehe but I wsa under the impression that a 2 way diff lets you put the power down better as its more like a locker diff and a 1.5 way fiff is better for track work where you go around corners

When I'm warming my tyres up sometimes one wheel stops spinning which makes me think the same thing is probably happening as i'm launching and changing gears, So surely with a 2 way diff this wont happen and it will help me with traction?

Nope Buster, a 2 way diff works the same (ie; locks) with power on as it does with power off (as in under brakes). A 1 way diff only locks up on power on, but free wheels on power off. A 1.5 way has around 50% the locking on power off as it does on power on.

So for a drag car we would only use a 1 way. For a rear wheel drive circuit race car we would use a 2 way (helps prevent the inside rear wheel locking up on corner turn in). We find a 1.5 way the best on a front wheel drive circuit race car as it allows a little slippage ender brakes accross the front wheels which assists the turn in.

Hope that helps

OK guys; lets get this ECU debate started, last time I looked WOlf hadn't released the plug in 3DV4 for Skylines. I had heard it was out in beta release, but there were some in field problems. Hence it is not on the their web site. Let me check..........

Yep, they still only list S14 200SX.

mmmmmmmmmm?

Don't get me wrong I am not picking on them for not releasing it until it is perfect. But Power FC's are available.........

Sydneykid, We're not trying to pick on you here, just trying to highligh the facts. I've had the Wolf 3D ver 4 plug'n'play in my car now for many months, they are just releasing ones for GTR's in the next month or so. Steve-SST knows more as he does alot of development work.

I found this on there website, hope it helps:D

We have just released the start of our brand new range of Plugin ECU's.

Nissan GTiR SR20DET

Nissan R32/R33 GTST RB20DET/RB25DET

Nissan S13 180SX SR20DET

Nissan S14 Series 1 200SX SR20DET (76 Pin Connector)

Nissan S15 200SX SR20DET

Delco V6 and V8 1988 - 1992 (Manual)

Mazda 1.6L MX5

The main reason I bought the diff was due to the fact that my current LSD open wheels under high power, therefore having the power going through two wheels with no slip should improve my 1/4mile time. My car is not a drag car, and I'm hoping to also do some circuit work and drift work in it, in which case a 2-way diff is an advantage:D

No Steve sorry it wasn't just aimed at you, as I know you will race and have raced in the past, theres plenty of people I know with big power though that don't race or have raced and just can't get the times because all they've got is a dyno sheet hahaha and not a well tuned car with good midrange/useable power  

Your a lucky guy though getting a fully prepped track to race on, Hopefully soon with the new drag strip being opened in Sydney we'll get a fair go too and more then 3 runs a night/fortnight

Buster, you should come for a drive to QLD. Willowbank opens in 3 weeks with the new track (its been re-surfaced). At times you can get up to 6-10 runs on Wednesday night.

Rob77 was going to the strip on wednesday night.

Does anyone know what happenned there...?

Yeah, I dont want to talk about it too much it was a costly night. On the way home went sideways through a roundabout cos I just didnt see it and locked up the brakes. Luckily it seems my wheels need an alignment (steering wheel vibrates when doing highway speeds), but I decided to put the 18" rims on the rear, so I spent $700 on rubber., as one of the 16" rim tyres was shredded when I hit the kerb... came out of it pretty lucky I guess, could have hit a pole or damaged the control arms or other suspension bits. Hence all my time slips are not on me as I removed them just incase (insurance). I didnt go through insurance in the end cos all I needed was a new tyre (oh my sideskirts stuffed, but they are only $100 each). Anyway, my quickest TS was 111mph, my quickest ET was 13.888, I kept dropping off on power between gears, I couldnt get any traction (combination of badly prepped track and street tyres) and my best 60' time was 2.6seconds (I think, trying to remember). I'm thinking I might have to buy some slicks and try those on a fully prepped track. I hate to say it but kwinana seems to be getting a bad reputation. Anyway a costly night... been pondering selling the car anyway, as if I hit a pole I might not be here today :)

Oh I have to add the car drives so much better on the street than the strip. And I'll post more details about my ET's when I have the slips handy. I found the best way to launch the car was drop the clutch at 3500rpm, although I didnt get a chance to run again and try 4000 or 4500rpm :)

5 or 6... from memory my 60' times werent improving a great deal, but I managed to wipe 1 second off my worst time, which was a 14.7... anyway, when I have all the time slips at hand, I'll post the full details of my best and worst runs. I found it interesting that I went a full second quicker yet much didnt appear to change on the timeslip.

    • @soviet_merlin Thanks mate!  Nothing too major but will hold me up for a while. I've got lymphomas to get taken off the back of my neck and the middle of my spine which always conjures scary thoughts!  It sounds worse than it is. Yeah great, conjuring more rabbit hole deepening , just what I need! 🤣  
    • I'd argue the F50 kit I got is very good value. For ~2k I got the calipers (refurbed condition), adapters, pads, brake lines, rotors, and top hats. I think you'd be pretty hard to get Evo/GTR/350z brembos + the additional hardware for similar money. Used market for a pair of front calipers alone I've seen tend to run anywhere from $1500-2000 depending on condition.    That said, something like a GTR or 350z brembo is a lot easier to adapt to the Silvia. 
    • Is there a significant price difference between the Evo/gtr/350z brembos vs the F50? Looks amazing.
    • I was actually being a tightarse at the time LOL... My OCD is tickling me into running a 2nd 8AN Teflon hose all the way down and removing the 2x OEM hardlines. My other side of my brain is telling me to run 2x hardlines front to back (also acts as a fuel cooler, so win win).
    • As I mentioned in an earlier post, I had some trouble with the Silvia's brakes dragging back in 2023. I managed to sort it out then, but the same problem came back to bite me late last year. Just take a look at the picture – I had a feeling the handbrake was acting up again, and I was right. Anyway, I'd been wanting to upgrade to bigger brakes for a while. Not that the Silvia's brakes were bad, but it was more of a "want" than a "need", you know? It was funny, though – at the time, I couldn't find any Evo Brembos, 350Z Brembos, or GTR Brembos for a decent price (of course, tons of them popped up online after I already bought my kit!). I ended up going with an F50 Brembo kit, which came with adapters, brake lines, 330mm rotors, and top hats. The F50 Brembo caliper was used in a few other cars too, like the FPV. I also decided this was the perfect opportunity to ditch the Silvia's ridiculous rear brakes and that awful handbrake (some of you were definitely right about that!). I picked up some R33 calipers and all the necessary bits – rear drums, backing plates, and new hardware to refurbish the calipers. Of course, it wouldn't be a project without a few hiccups. Turns out the brake master cylinder was playing up and basically (to put it simply) keeping the brakes engaged. I had it overhauled, and after some adjustments, everything was working again. The whole process took a while, as you can imagine. To top it off, the front right wheel bearings were shot and needed replacing too. This is a rare occasion where I'm posting an update while it's all still fresh! These pictures were taken just this afternoon.
