How would this run? Mainly curious about timing, as i have a SAFC2 to get dyno tuned im just wondering what my best option will be, i am running 370cc injectors.

Do anyone know the timing maps for the 25DET and the 25DE ecu's? I can obviously change the base timing, and the A/F ratio's, just wondering what would run happiest (as obviously running an RB25DET ecu would make life easier with the injectors etc). Since the RB25DET is lower compression, i was thinking timing might not be too different, and if it is, maybe theres more down low, meaning i could up the base timing so i can get more low end before it maxes in the top end.

few specs on engine, its Don's old engine, which is an R33 S1 RB25/30 with 1:1 RR FPR, 255 & 8.3mm cams, VVT, 10.5:1 CR, 6800rpm limiter, peak power @ 6000rpm, peak torque @ 5000rpm, dyno'd with 150.9RWKW with the safc untuned.

Im putting thermo's on it, replacing the dodgy molestered press bent 2.5" with full twin a 2" mandrel straight through system (equiv to about 2.85" pipe), New larger extractors (the secondary's are whats joining to the twin pipes, they will never meet up [completely seporate] should sound lumpy), also making up a decent intake, Y piecing the twin TB's into one large pipe, feeding to the front with a proper enclosed CAI.

Asked in N/A section a week or so ago, no relpy's

      What should I do next to hold the head on

      By MBS206 · Posted

      When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?

      Chris' Toyota Mark ii JZX110

      Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.

      new 1.5 LSD issues/concerns

      If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
