Click on the youtube link people...i think its actually posted by F1?????

Truth is if i could yave my time again with singles on the RB25...TDO6-20G with 8cm if on E85 or 10cm if on 98 The 8cm is really too small but with E85 it masks the mismatch. If 98 you need the efficiency on the exhaust side and IMO need 10cm The 20G was just pulled everywhere. Perhaps if my motor liked boost i would have liked the T67 more. But i had problems with the engine not making more power at 22psi than 18psi...assume its valve springs in my motor. Lol so i reserve to change my mind if with 24psi my T67 had made the 360-370i expected i may have liked it more than at 330rwkws which was only 15rwkws more than what i strangled out of the TD06-20G

Really...pretty sure i was almost at 200rwkws with no ebc or vct

I have ran a TD06-20G with a 10cm housing and 8cm housing on an RB20. Difference in response is HUGE. No difference in power I have ran a 12cm housing and 10cm and 8cm housing on the same TD06-20G on an RB25 and the response is light years different again. 8cm was mega punchy but fell over after 6,000rpm. The 12 cm was laggy and basically the 12cm-20G on the RB25 was the same as the RB20 with 20G and 8cm...so big step backwards. The 10cm was the sweet middle, pulled well to redline but certainly wasnt as violently response in the 3,000rpm range as the 8cm I quite liked the 8cm on the RB25. If my car was purely street I would have kept it as it drove like a diesel truck. But the lack of top end would have annoyed me when driving at the track

I guess they have the active dff so perhaps they try to help dial out understeer by running a higher rear spring rate I used to grab bits off a V8 Supercar guy and when he was at Kmart Racing he told me there was a big difference to how Rick Kelly and Greg Murphy set up their cars. If memory serves me correctly Murphy loved as much bar as they could throw at the car whilst Kelly liked more spring. I ran big bars at one point in time and whilst the car was generally about as quick as it was with the other smaller bars I have run it did handle and feel very different. Not sure porpoising is the ride word but it seemed to feel as though it crabbed around fast corners..just felt odd. With smaller bars it just feels like the car handles what I would say is more natural Russman now runs my old mega bars in his Time Attack GTSt and its friggin quick for a basic car so they obviously work well with the Tein RS setup he runs. But for me I ended up with my ARC bars that generally felt the same at the off the shelf Whiteline offering but are larger diam and hollow so lighter but still adjustable in the rear.

Frankly I would be going DMS or MCA, lastly Bilsteins. But all three would be decent enough things though I tend to believe the DMS or MCA will give you a slightly more focussed result. The critical thing IMO is to decide what tyre are you going to run. The TYRE is CRITICAL. I agree with much of what GTSBoy has stated but since you have mentioned 30% track car its important to remember that your car with such low spring rates and modern semi slicks will quickly find itself out of its depth. At the end of the day you will need more spring and associated damping to handle the grip an A050 will give you. But if you are going to street tyre, even a grippy street tyre like AD08R you wont generate the grip to need higher spring rates. This is full Whiteline kit. Back in the day my car was actually the Whiteline development car, so low spring rates like GTSBoy refers to on near new RE55s This is the same turbo setup just with more boost so 40rwkws more and Tein RAs revalved by Racepace with F7/R5 springs running old A050 tyres The difference in stability is huge as with the lower spring rates and grippy tyres there was simply too much pitch under brakes, squat under power and roll in corners that loaded up the suspension. You can see I spend most of the lap chasing the car with steering input The kicker is I think the Teins with higher spring rate actually are less crashy on the street. In general driving you can tell they are stiff just with how the car rides the bumps but they are actually less crashy over expansion joints and the like because I suspect the Bilsteins valving is more agressive than the Teins.....so dont discount the actual valving of the shock and in turn the ride...its not all spring

Holy shit https://youtu.be/RQmMYTBS_F4 Since when? F1 finally woken up

I am sick to death of him just driving Rosberg off the road...he barely gets a wheel alongside at Barcelona and lunges at a closing gap because he thinks there is a gap and has done enough to be given space but when Rosberg has plainly driven around him is easily alongside and has the inside line for the next corner he "understeers" again into Rosberg. Its crap and robs viewers of good racing. Hell Max showed how its done...amazing job by the young punk

$500 + postage so I can afford more beer whilst on holidays

Oh...and if you dont know who Ben Manion is have a read on his Targa Tasmanis results...on public roads his car hammers...RB20 and hi-flow turbo Not saying they are the ultimate...but you can't say they dont provide great performance when Ben Manion has won early modern and him and Ben Wooster always run competitively in the tarmac rallies in their lil GTSts

Even the Pirelli fella aHembrey said 3 stop is faster on paper but everyone is likely to 2 stop due to traffic and difficulty in overtaking

Well for a long while it was the fastest rwd car in SAU Vic track days. It often nibbled at the back of the top 5 overall. The Racepace GTRs generally quickest. Russman and Richo obviously lifted the bar but i was never going to strip my road car and slap aero on something that is daily driven For years a few of the S-chassis and RB25/30 folk joked that i was running a built RB25DE like i am these says. They didnt believe i was still running a std RB20 as they couldnt match my Sandown times and that place is largely a straight up drag race from 50km/h to 230km/ It got top 15 results at Winton, Sandown and Phillip Island at years of Dutton Rallies....including top 10 on occassion. That was in grids of 100 cars, Evos, STIs, Porsches etc etc Ppl that go on about them being gutless...i get that but also means you dont end up with much of the torque of bigger RBs just giving you wheel spin. It uses all its power and accelerates the car vs going sideways. May be boring but effective. As i said how can you say a car that is quicker than 997 GT3s is shit? It aint perfect...and there are better setups out there. It isnt special either as others have done the same turbo setup and got the same result. Oh...the JMS Onvia made good power but was running a 12cm housing off a rotary...not the correct 8cm housing do is a poor example Thats the trick to a good RB20 dont be a JMS and usecwrong buts and bobs because they are cheap. Use a good quality 80mm exhaust and good 60ox300x65mm ic. Run a proper ECU tuned for your car....its not rocket science but most RB20s are in the cheaper end of the Skyline world and the quality of the mods reflect that...no better example being the RB25 turbo upgrade which i get is economical but ends up not being overly different to my TD06 on the street with regards to power and drivability at 3,500 and is left for dead from 4,200rpm Thats the trick really...get a turbo eith a 60-70mm compressor and a turbine housing that reflects the fact its a small pot 6 cylinder and just use the 8,000rpm Nissan gave you. Hell Nissan gave you a 4.3 diff for a reason...i had a 4.6 diff i was going to install but never did...i reckon it would be the best $500 upgrade going...after all its the road speed where you make power that is important...not rpm

Each to their own. But I give no fux about driving like a retard on the street but I can tell you a 12.9 qtr mile car walked off the line with a 2.3 60ft is never going to be "shit" as you say. A track car with good drive off corners that is just simply quick everywhere is ...surprise surprise its going to be a very quick street car Take Winton that has a load of slow 60km/h corners and I still take them in 3rd. Its even quicker if I rape it in 2nd but I am more about circulating and enjoying it and not raping the car that is largely std and drive it in a manner that reflects my hip pocket Like I said it aint perfect...if you want a street car that drives like it has an LS and allows you to take corners in 4th when it is well within the mental faculty of the driver to actually grab a gear that puts revs at 3,600rpm vs 2,400rpm to drive out of the corner then there are going to be very few instances where a well sorted RB20 is going to leave you wanting. The car makes 200rwkws at about 4,200rpm....how the hell isnt that a quick, fun street car? For me it is. Maybe not for everyone....but if you try to frame the discussion around facts and not...I spent 4k on a 200rwkws RB25 transplant so it has to be awesome because I like it....even though my car is a slow sack of shit LOL, enoough 16yr old punk smack talk in my post to make me right GTSBoy...what is your frame of reference for an RB20? Have you actually owned/driven one with a well sorted setup? I recall reading you own an RB25 powered R32...what was your starting point and where are you are with it?

They are a mega impressive camera. Give them 24 months and GoPro and anyone else that wants to compete will have to offer an equivelant. Meanwhile. I just loaded up on spares for my RadCam....at least I know it in and out

Yeh RB20s are hopeless 260rwkws reliable track car on 98, 270 on 100. 306 on E85. It aint perfect and you can of course do better. But BS to them being rubbish when a completely std engine with bolt ons can bag you the same lap time as 997 GT3s around Victorian tracks!

Sux to be Russian

So Nistune is good with big injectors? A mate had trouble with his 330rwkw SR setup and tuner kept blaming Nistune and the 2000cc injectors (think they were 2000s) No idea if it was fact or just blaming as it was the easiest escape goat. He gave up on cars and being raped by all the Sydney experts so sold the car.

You will love it. Epic event that a car race breaks out in the middle of

I was...now i am only a small chance. Combination if nobody else interested as was only going to be and one mate plus a 3rd who would be working. Also the hiccup is i am going to Monoco so trying to save some cash and hoping to do Le Mans next year. Will see how the year pans out but may do Fuji

Any feedback yet? I need a new camera and dont have many pennies

The car is on blocks still So who knows... I am mainly doing it for strength as the 32 cradle had cracks and long term with the new engine thicker shafts isnt a bad thing. Meant new shocks and diff which sux but everything is new do will be mega. Running GKtech offset diff bushes I dont think the rear is any wider. I think the wider track is from the offset and width of wheels...but would have to check again The mount is neat. I run their gear in my Cossie and gets the job done

So whilst working my way through the suspension re-bushing/bearing everything that could come out I decided to get carried away with painting stuff. Partly so that all teh light colours will show up oil and partly so I could strip any parts I was re-using and inspect for cracks etc. And partly that it will be nice for the car to be clean and neat for the frist 6 months that its back on the road Got some chrome moly pipe cut and threaded to the length I needed for my new front LCAs and had them coated before painting them Going to the R33 GTR rear end meant I had to get a new diff so went for a Nismo GT Pro 1.5 and grabbed a Trust diff cover to give it an extra bit of volume in attempt to keep the rear end consistant over 10-15 lap sessions without going for a diff cooler. Who knows if the extra volume actually makes a difference, a Trust bit is cool all the same. And with the rear cradle about to be all bolted back together and into the car I have the new gearbox cross member to allow me to throw the RB25 box in after givign away my RB20 box to a mate with a 260rwkw SR20.
