hey,

Just got my fmic install and now are able to run 0.8bar of boost (12PSI) but now if 1st gear i get abit of lag the car doesnt kick in full boost tiill between 3500/4000rpm. The car is a s1 rb25det, my turbo has always been abit of "we arnt to sure what it is"

i know for sure it is BB and does look like the front is stock but possable be a hybird with a vg30 or vg20 rear end.

my mods are; exhuast (stock dump), air filter, fmic, bov, fuel-pump, and ebc

is this normal? i made only 212.7rwhp @ 12psi in shootout mode, there is no boost spiking, many similar modded r33 in perth can make from 220 to 240rwhp

thanks michael

id get another dump pipe and a hi flow cat if u dont already have one, i installed mine and it spooled up alot quicker...apart from that not to sure...

i made 150rwkw with 11psi, full exhaust, air filter so id say a dump would help rid that gas quicker...

What ben said, dumpipe will help with turbo spool up and will give you a power increase that is noticable.

You will have to re-set the boost again as it will be different when the exhaust is flowing properly with out back pressure.

Have you got any picture's of the turbo ?

Don't worrie about the car's in perth they seem to have different results to comapred to the results over the east side.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.

      ECU sees many times the speed than speedo does (R34 swap)

      It's needed for rolling idle up, and I think it is a decider on VCT also.

      I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
