Hello from Telemark, Norway

Hi all,

I am a 32 year old Norwegian, I work as an engineer, and i am a huge petrolhead. I especially like RWD cars with straight sixes:)

I try to do most of the work on the cars myself, but I don´t know so much about EFI tuning, and will try to learn more about this.

My car is a 1987 Nissan Laurel, modified in virtually all areas. Currently running a RB25DET with Vipec V44 plug in, ID1000 injectors and GT3076R turbo with 1.06 AR Twin scroll exhaust housing on a homemade ex.manifold. Its making 470hp and 570Nm at the hubs on a Dynapack.

My goal is to build and install an RB30 engine, and to tune it myself.

Hi JFinken,

Welcome to the forum. That's some impressive figures, what boost are you running to make that?

Thanks Chris.

I`m running 1,4-1,5 bar of boost. It`s a pretty basic setup really, stock longblock and cams, but works quite well. The twin scroll exhaust housing do make a huge difference in the low end of the powerband and driveability.

So not even a metal head gasket? I always keep boost below 1.2bar for safety (paranoia) on stock blocks

No, stock head gasket. It`s probably quite close to the limit though, but i haven`t had any problems with it. I have used it on track but not for extended periods on full throttle. For hard use like serious track driving for long stints a limit of 1.2 is probably more sensible.
