Hey whats up. I have been having a problem with my car. I was thinking it was my spark plugs but I just changed them out today and I am still having the problem. It seems as my boost gets to .7 my car supters like there is something wrong with the mixture. I was boosting 1 before. I have a metal headgasket, aftermarket turbine, wastegate, and many others. I also have 550cc injectors and a GTR fuel pump. I have not done any adjusting of the tuning so I dont know what is wrong. The only I have done is used on base gas which made my car run like crap. But since then I have used off base Japan Super Octane and ran fuel system cleaner threw. Any ideas? It seems like this always happens at .7 boost. Thanks for the help...

Well I fixed that problem but I have another one from something that happened last weekend =(

Well this past last weekend I checked all my plugs and coil paks to see if I could fix the spudder problem. Well I sanded down all the igniter plugs in the coil packs so I would get a even contact because before hole was burnt out of them and it wasnt in the middle. I also stretched my springs out to try and compensate for the shorter igniter plugs. Well I drove my car and it was running really good, wastegate was opening and no spudder. Then my friend thought he could fix why my car idles so high and he messed with the trottle position sensor and the idle adjustment knob on the rear of the engine. Well he messed with the idle adjustment and said that it wasnt working right and that maybe the spring inside was gummed up so I tried taking it apart and putting some choke cleaner in it. Before he said he could turn the screw and the idle wouldnt change very much, that is why I cleaned it. One other thing that was done is one of my springs broke in my coil paks so I have a spare R33 coil pak so I just used that thinking it would be alright... Well when I started to drive home after that guy messed with some of my stuff I would drive and my RPM would just drop and I would have to push in the clutch and give it a good steady push on the gas pedal or else it would die.... Even if I was just driving normal it would cut out... So I drove my car to work a couple of days and it would do it everytime I would go to and from work and it would always be in about the same place going different directions to work. Anyone have any ideas? Maybe because 1 coil pak is a R33 coil pak or maybe something else? Please help me.... Thank you =) and sorry about the novel... =)

Also how do I set my idle adjustment right? and the throttle position sensor? Is there a diagnostic I can do on it?

      I agree on doing some better than factory pistons, rods, and oil pump. For anyone using the vehicle on the road, I don't get why everyone wants big cams. The stock cam profile, with some more lift would be mint for road usage. Everyone going big cams and then wondering why it isn't as responsive in traffic, when they've shifted the torque curve upwards an additional 1000RPM. Make torque, at lower RPM. Sure it's not as cool as claiming "500KW" and revving it to 8,0000RPM, but that same torque 2,000RPM earlier... Then you don't need the extremely high end pistons and rods, and blah blah blah.

      Personal experience. Those f**kers burn. And are actually a PITA to put out. Next time I walk down the back, I'll snap a photo of what the inside of the bonnet looks like when that thing ignites. PS, powder fire extinguishers are useless on that stuff too as it's fibrous and when it ignites, it starts to pull apart. And you end up just blowing powder through a sieve effectively.   Like the big thing is, if it's fire resistant, it's job is to stop what burning? The METAL above it? It's just to try keep heat off the bonnet paint work.

      That's more or less what he meant. What it really means is that you do not have to go full crazy on the build. Don't need the best oil pump, expensive rods & pistons, big cams, etc. You can upgrade whatever you want instead of using stock level items, but you don't have to. Having said that - any time an RB is opened up, if anything is getting replaced, I think the opportunity should be taken to do all the sensible upgrades. Pistons, rods, pump, etc.

      February update 🙂 We managed to get the very last 1/18th "Extra Scale" cars stock available from bookstores in Kyoto. These are actually the last ones and will not be restocked again! Hachette Collections Japan have not decided on a release date for these or other models in the series, so for the time being these are all there are available new.  These are showing up on Yahoo auctions at inflated prices already (especially the Celica and NSX) so get yours now at a very reasonable price before they disappear! Stock quantities: NA1 Honda NSX - 1 left: https://www.oemsoko.co.jp/products/1-18-extra-scale-1990-na1-honda-nsx 1973 Toyota Celica LB 2000GT - 2 left: https://www.oemsoko.co.jp/products/1-18-extra-scale-1973-toyota-celica-lb-2000gt 1968 Mazda Cosmo Sport - 2 left: https://www.oemsoko.co.jp/products/1-18-extra-scale-1968-mazda-cosmo-sport 1970 KPGC10 Nissan Skyline 2000GT-R - 2 left: https://www.oemsoko.co.jp/products/1-18-extra-scale-1970-kpgc10-nissan-skyline-2000gt-r
