hey guys.. i have a r33 s2 skline running an aftermarket kkr430 turbo with stock comp/injectors. it gets to about 4,500rpm and stutters/cuts, was running 14psi on the stock gate..so i got a boost controller and wound it down hoping that it was factory fuel cut/boost cut?... but it stil does the same thing even on very low boost, was running fine on the stock turbo, wat do yas think the problem could be? maybe just needs a tune with the new turbo? any help would be awesome :D cheers.

The new turbo will be much more efficient than the stock one, so can produce more airflow at lower boost levels.

Best idea is to ditch the stock ecu and get an a/m one tuned, or you could try a piggyback

ok sweet, wat about an fcd? or a tune? or do i really need the stand alone ecu? im trying to save cost here lol :D

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Sorry to hear your HFM BM57 was faulty,  did you contact HFM I would hope they would be at least grateful for the information if there was some sort of manufacturing fault, you would hope they would be sympathetic even if your item was 2 years old if it had never been fitted. May I ask where it leaked from ?

      Cats are called Bella, and Donna...  Like that poisonous plant And I remember your 2 monsters, I remember making a little bit of wee when you let them out... LOL I have already installed cat doors into the laundry where their kitty litter is, and the sun room, apart from the cat doors there's not going to be any permanent mounted stuff on the interior walls (interior doors are cheap and easy to replace) I will get a outdoor cat cage thingie once I finish the landscaping out back... https://catnip.com.au/ The only off limit areas are the main bedroom and the gym room....but, currently the cats are curled up in bed, in the main bedroom with the Mrs.....LOL, the off limits for the kittens to the main bedroom lasted about 5 minutes with Jackie I currently only have 1 free standing huge cat tree multiple level scratching post thingie in the lounge room, but, I will be getting another one soon now that I'm happy with the furniture layout in the back room and have a perfect spot for it

      All of this is making it seem clear that running the Coppermix twin was definitely the way to go, especially in hindsight with how insane tariffs have gotten and the strength of the USD vs yen at the time.

      Who has a Infiniti Q60, Q50 (V37)?

      That sounds like no chance of even importing one for road registering then Now I see why Duncan wants to check LHD rules for Targa...   I wonder how "bolt in" the AWD would be if you got one imported from the US and swapped it to an AUD one
