thank you very much. RB family has been helpful and also was a source of inspiration.

i will test different A/R s on the exhaust side, different cams and try to find the best combo on my Dynamics. BTW you Aussie people have a wonderful Dyno, and i am also a lucky owner of dynamics dyno as well.

dyno dynamics are ok but if your serious there is only one dyno and that is DYNAPACK..... far less hollywood, far more accurate and repeatable (especially at the kinda power you are talking 800hp and up) and no harder/longer to setup than a roller.

fkn sweet cars BTW i would love to drive that twin turboed bimmer.

Not harder or longer to set up then a roll on dyno??? lol

Ill stick with the rollers.

HP on dyno's is Hollywood full stop regardless of the type.

Nice setup on the M3 :)

I'd be having a look at what borgwarner/airwerks have to offer. They do a 91mm turbo and a few other sizes between that and the gt60 sized compressor which is huge.

Precision has a range of 91 - 94 - 98 - 101 mm compressor wheels but i want to stick to Garrett.

A 98 mm falls between a Gt55 and Gt60, but i insist on Garrettt.

Thanks mate.

I drove the 2.8L twin 2871 for 10 kilometers, then we decided to change the ex manifolds, and i fabricated tubular manifolds. as it is a hobby, it took some time. And a bigger intercooler is in place.

first minutes engine did not pass over 5000 rpm. I was shocked. Boost was 3 psi. Then i realized the ECU had a safety rpm cut at 5000 rpm. Removed the limiter.

During that 10 kilometers test drive, it was like sex driving twin 2871 2.8L

Now, with the 3,2L and 3,9L capacity, the feeling (power) may be amazing, assuming all go well.

Dynapackk, more time involved for wheels etc.

But you guys should be proud of Dynamics, what a consistency and quality.

    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
    • Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
    • Hi All, putting the engine back together and everything is perfect except have this plug left over.. any ideas what it is for and where it goes? Is on cold side under the intake plenum *note not a stock plug, as everything has been modified Cheers
    • Sounds like a misfire. Check fuel pressure and don't even think about going into boost while it's like this unless you enjoy engine rebuilds.
