  1. My turbo is a ways smaller than a GT35 but I can tell you going from 98 to E85 made stuff all difference to response. If anything it is slighlty worse. What is better is just how much torque the car makes, but the sensation of when it boosts does not change. I think the GT35 is simply too big a turbo for any 2L unless you are going to have valve springs and oiling, PS and water pump pullys all geared so that you can pull 9,000rpm as the thing is unlikely to start making +250rwkws until after 5,500rpm. Also, since you are looking at running a gob smack of boost I think you are better of going for a smaller turbine and compressor and driving it harder with a larger A/R turbine housing.Whilst the GT35 has a good sized turbine, pushing that air through a 0.63 housing may result in a peaky powerband that falls over up top. Better to go a smaller turbone and compressor with a larger A/R turbone for a similar power level but generally better torque band and better cylinder filling/exhausting If you are going to run that big a turbo I also suggest you run a plenum. They seem to genreally further hurt response but they do tend to help the power in the high rpm range over 7,000rpm
  2. I was in the Brabham stand too and thought it was Bottas going off...though it was Pastor who finally beached it. In other news after looking at the Mazda stand I want an RX7 SP rather badly. Would look sick next to my Sierra ..and on other other news...Webber had no KERS for the first half of the race. So sorry Mark for abusing you from the stands for not being able to get the job done on Button
  3. I think you will find an amazing number of drivers who win in Aus go on to win the WDC. From there the constructor that wins in Aus normally goes on to seal the deal Stoked Kimi got up and made it easy. Made flying my Lotus colours today a lot easier. Shame that Webber, Dan and Romain all struggled.
  4. Well have to take the good from the bad and it seems that Albert Park was pretty hard on cars so going to focus on the fact I was fortunate to not have made it as it may have broken the car more than it already is About to head in...going to be a lottery dip. Funny, when Webber was in a nowhere car I loved wet races as it gave him a chance. Now he is in a car that is in the hunt I hate wet lottery races
  5. Looks like its going to get cancelled. Perhaps Sunday morning Q2 and Q3 ? Glad I decided to go put a new loom in the car today rather than go stand in the rain
  6. Look forward to the DNFs. If they make the distance it will be ahuge accomplishment...if they place then be rather mega
  7. Yep, all looks period
  8. Boost response wasnt really any different between E85 and 100. On 98 it used to start spooling at around 3,000rpm. At 3,500rpm generally had about 5=6psi in it and would make about 18-19psi by 4,200rpm
  9. Well thanks to the scumbag crooks that tried to steal my car the other week I am now not able to do the full speed laps around the Albert Park circuit and it appears I have pissed my money into the wind ... oh well. That is life with cars I guess. I bet Webber sux balls this weekend just to rub salt into my wounds. Kimi will probably blow up and Roamin take out Dan in the first lap.
  10. That could coincide with the R32 RB25s and makes sense.
  11. Yeh, my old R31 had these rocker covers on the the later model R32 engine it had. I left them the std R31 colour and just rubbed back to ribbed tops. I think they woudl look better if they were the std R31 colour rather than lipstick red...but meh. By the time they are covered in blow-by wont be able to tell
  12. Yeh, will be interesting to know. What the guy was telling me made sense as the RB25 didnt really spring up in any Nissans until the R32 GTS25 which was a mid cycle thing from something like 92. So means that Nissan were using the RB25 block in a car before the R32 in a late 80s export market car. Be interesting to know what sump is on them as I guess the RB26 was around so that is closer to RB25 family of blocks!?!??!
  13. Are you sure about the DNA of the engine. SOme lads in Singapore and Malaysia ran them in their drift scene and looking at them in KL (around Puchong) they told me they were RB20Es with different internals, not RB30Es? And with a bitsa car there is a good chance its an NA R32 RB25 that has been turbo'd due to loom compatability etc
  14. Weren't the factory RB24s SOHC and carbie? RB24s actually use RB25/26 cranks so they are not actually using an RB20 crank and have the same stroke. They cant run the same bore so at 81-83mm bores thats where you lose the displacement R32s did come with RB25s. They didnt have VCS and were NA with visually identical manifolds to an RB20 so ... Also, RB25s head wont be able to be used on an RB24 bottom end. Not without loads of custom work so not going to happen so need to be RB20 based heads
  15. How do you find the front brakes? On paper should be ordinary but results often dont translate from paper to reality
  16. And to think she is now tarnished with bits from its dirty easy sister. I feel so unclean. But when it goes bang will gladly throw it in the skip for being so inferior to a std RB20
  17. Well its not a 20 crank:)
  18. Std head just serviced...std cams for now and some baseline results with 20G before i try new turbos and cam combo
  19. Its a DEI product and can get it from Speed shops like Revolution Racegear As for the engine it maybe has a few more cc, ARP head bolts, Eagle rods and Arias pistons
  20. You can easilt use the wrinkle paint as your base then put a colour on top. I have mine in red. I may end up going over it with a deep maroon with a bit of gold pearl through it as the red is just a little bit bland and straight forward and woudl like to go to the colour similar to what was on the original R31 rockers.
  21. I I am at work today but its a waste of time...my brain is already in Paris drinking cans and hitting on French girls with hairy armpits
  22. Well after abusy few months with a new job/project and slowly re-wiring the Sierra and rebuilding its engine...I put it aside to do a few weeks of rather intense work on teh old R32. Its now just about ready for a full years of track duties. So did some re-wiring. Re-sprayed the engine bay....did a load of other minor tweaks...and then put the 20G backl on for the first round of back to back tests provided the new engine isnt a shitter and craps itself on run in The new heart Re-sprayed and DEI'd up engine bay Sitting in the tarted up engine bay Tucked away in the corner with her older sister until I get back from Portugal in a few weeks
