Yeah, too true. That was the idea of finding out... Briant (the owner/builder) wants to machine one up from scratch, but simply wanted to compare the standard TB42DE flywheel, to the RB25DET they bought to throw in the car. Most of this is R&D, because the RB motor will likely be copping the GQ's FS5R50A transmission. He's a machinist, so making the components is not an issue for him. Thanks again Elite/Daniel.

Guys, thank you very much for your time! I do find it interesting that they kept the same flywheel from RB20 through to RB26 though, on all models. Strange indeed. But I guess they knew what they were doing, and that's all that matters. See I hail from the Pulsar mob... SR20's are commonly used, and there is a distinct difference in the variants, from RWD to FWD/AWD and GTiR. GTiR is commonly known as the black sheep, because 99% of it is different to other SR variants, and thus usually not interchangeable. The flywheel & clutch is one of those things... Ours are around a 215mm clutch, and the GTiR is around 245mm. Then of course, the flywheels are different to compensate. So I figured maybe there might be a difference between models in the same fashion, but obviously not. All the same - I got the information I was after anyway, so thanks again guys! Rick.

Not necessarily, things aren't always engineered from an aftermarket point of view, they're engineered to a torque rating. Every manufacturer wants their vehicles to see out the warranty without paying out the nose for ongoing factory recalls, so things are always engineered or over-engineered to withstand a minimum specification. The 'X' amount of extra power & torque from the 2.6 litre, plus the increased load on the drivetrain from an AWD format, means generally they'll install a larger clutch, to compensate for that. So the flywheel will be larger, respectively. That doesn't necessarily mean it's heavier, of course. But they could have just provided the same flywheel for all models/variants, but I don't know... that's why I'm here!

What about a standard RB26 Flywheel? I'm going to assume they're physically larger, hence heavier?

Thanks guys, cheers for that!

Hey guys, I've had a bit of a look around, but I can't seem to find a definitive answer. Would appreciate something from the tech-heads preferably, but anything's good so long as it's accurate. A couple of clients/friends are building a GQ Patrol for the SA Offroad Champs, and the vehicle is going to have a mid-mounted RB25 in it. Under the regs of the sport class they cannot use the standard motor, and would prefer to run a forced 6 cylinder instead of a V8, so the motor is going to compiled from an RB25/30 combination, as the motor must be < 3000cc. More to the point, the car is being built to a spec is mindful of their budget & class. That's not the current concern though, currently they'retrying to sniff out some information regarding the factory RB25 flywheel, because the motor was an automatic from a Stagea half-cut. How much does the factory flywheel weigh? No need for suggestions on aftermarket options either, the guys are machinists amongst many things, and will be manufacturing most of the components themselves for the vehicle build. While I'm here too.... This is unrelated to the topic title, but - What is the torque/power rating of the standard RB26/GTR transmission? Cheers in advance for any help, Rick.

Bump!

Bump..

Hey guys, Item: 2x Hankook Ventus HRII 215/40R17 Performance Directionals. Location: South Australia. Website: Here. Item Condition: Brand New. Reason for selling: Unwanted/Unneeded. Price and price conditions: $320 ONO + Postage. Extra Info: I bought these probably around 3 months ago. I bought only 2x for the front at the time, cause I needed them in a hurry to put on the car for some tuning exercises.. had the intention of using them for a long time, but I no longer need any 17" street tyres now. Genuine sale - have changed directions with the car, which runs semi slicks prodominantly, and certainly not 17" ones at that.. so I really don't have any use at all anymore for 17" street tyres, thus - I need to sell these on. I would have kept them and used them otherwise. They are 215/40R17 in specification, and are Hankook Ventus HRII, which are their top of the range street performance tyre apparently. For the very little amount I used them, I found they were a very good all rounder. Was quite pleased with them, for a so called cheaper tyre. Sadly for me, I'll lose alot of money on these.. I have quite literally only used them for around 600km's, which included a trip to the tuners, and trip to and forth Mallala for spectating a Modern Regularity round, and the trip home. Whilst in use, they were used only for very light duties, no fast drives or the like. So these are practically brand new, despite being a bit dirty from everyday weather. I paid $190 each tyre, so I thought $160 each for pretty much brand new tyres is an ok deal.. I got these cheap too, they usually retail for around the $220 mark. Price is negotiable, but please be sensible with offers.. Would prefer to sell locally, but can arrange freight at buyers cost.. Any other questions - please feel free to ask! Pictures: Cheers, Rick.

Legend! Thanks..

Hey guys, Anyone have any wiring information on this AFM? It's a 3-Pin plug.. I'd assume it's just as follows:- - 12v - Signal - Ground Pretty simple to understand, but just wondering which is which? ---------- I previously had a J30 Maxima AFM in the car, and they use a 4-Pin plug The 4-Pin plug is as follows:- - 12v - Signal - Ground - Signal Ground So yeah, just wondering if someone can confirm this for me. Thanks, Rick.

Looks like you beat me dude..

Dooo Eeeet.... Beat Peter this year!

Yeah joined ages ago.. never post. I'm sure you do, now that you just bought an R32..

Yeah.. it was actually posted up, and in full swing back in october. I've just been a bit lazy with promoting, and I thought it had already been done here on SAU by another member of the PGA club. He had posted up about it, like 3 days after the last one was over.. The reasoning for that was because he had planned ot have it earlier in the year on a permanent basis, starting by kicking right off with next year to begin with! The only thing is, because this one ended up so late in the year, and because the next is ending up so early in the year, they have become real close together.. But don't be fooled... we promise a fantastic day will ensue! Rick.

Hey guys, The PGA-SA Interclub Dyno Day is on once again! Topic from previous day can be found here:- http://www.skylinesaustralia.com/forums/Pg...ay-t225222.html Just trying to get the word out to all the clubs. Last 2 days were a reasonable success, and a number of you bloke rocked up last year to show off some pretty tidy machines, and put out some pretty impressive numbers, which was awesome to see! The turn outs have been pretty good, but this year we want to make it huge! We had and do have a number of sponsors for the event, and hence prizes & awards on the day. There is also talk of a 50 entrant extended day, and a show & shine on the primary school oval adjacent GWW, but confirmation is yet to come. Link to official webpage, is below: http://www.dynoday.info/ Link to thread on our site, is below: http://forum.pulsar.org.au/showthread.php?...454#post1549454 Hope to see some more of you guys attending or entering once again!! Cheers, Rick.

Tell me something new!

Yeah I know what you're saying.. but sometimes it's just too convenient Once again, great to see the response from you guys!

I don't think that is a good idea anyways. The spots filled up within a couple short weeks last year, and this year they look they are heading in the same direction. Paying on the day would only be an option if someone pulls out at the last minute, and they offer their position to you. Alternatively you can pay via credit card, or have a money order sent. Money orders are generally safe, no money is physically lost or stolen. Only catch is it costs you $2 or something for one.. also, Lynette may not accept M/O's, so it is a good idea to contact her first. Rick.

As above guys - call and speak to Lynette. You can either get her to fill a form out, or fax yours through. Payment can be made via cash or credit card, she can do that all for you over the phone or via mail of course. Also agree - awesome response from you guys. Seeing other japanese candy on the rollers on the day, adds to the environment.

Wow! What a response from you guys, which is awesome to see.. Damo - It is a competition with prizes, etc.. but feel free to enter just to get a number for your own piece of mind. I know of a quite a few that did so last year, just for that reason. Myself being one. Please by all means enter, it was great to hear some RB burble on the dyno last year. Rick.

Hey guys, Just trying to get the word out to all the clubs. Last year was a reasonable success, although it was held on the same day as another large Adelaide event. The turn out was pretty good last year, but this year we want to make it huge! We had and do have a number of sponsors for the event, and hence prizes & awards on the day.

Cool, ta

Ahh, you are a champ mate! Yeah I'm well aware of testing the components, that is all ok. Main thing I wanted aside a diagram (which I've got now, hoorah) was some specs on the units. The unit is actually going onto a Pulsar, running a GA16DE+T (1600cc) ... Currently I am running the standard 2.5" AFM, but those are only believed to have a range of around ~3.4 volts, and so commonly run out of puff around 140kw or 12psi. I'm planning on an upgrade in the not so far future, consisting of an S14 BB T28, meth/water injection, and 15psi -hoping for around 160-170kw atw. I could have gone straight to Z32, but aside the fact I picked this unit up for $50, I really don't need it at this stage, and so I believed an RB20 AFM was to be suffice. Luckily for me, I picked up an RB25 as a bonus. So in hindsight - I really needed some specs on them, to ensure they were going to be suffice, and it looks like it will. One last thing, how much boost can you run through them before peak? As mentioned - they'd be able to flow 15psi easily enough wouldn't they? Thanks again mate, Rick.
