  • Skyline Engine MODS Database

    I noticed that although the forum is full of alot of info, a newbie really has to search through alot of posts to find what some of us assume is quite simple info...especially about our individual setups.

    I nopticed that we do not have one of these:

    I was thinking that anyone who wanted to could COPY/PASTE the following template to use and we could get everyone's info in 1 place so that we could compare, or newbs could compare without alot of questions, other than perhaps PM's to those who they are interested in setups by ?

    Here's what I was thinking:
    MAP or MAF's:


    Last Dyno Update:

    I would assume that we all don't need Dyno sheets, as a 300-350 HP claim on stock turbos should be believeable, but to have sheets where applicable and ofcourse, as an option, but not manditory unless you are claiming 500 HP on stock turbos and s stock bottom

    MODs ? thoughts ? Sticky ?

    I will go first, feel free to add, but let's keep this clean and to the point (advice that I myself have a hard time with most of the

    July 13, 2008 Update:

    New ECU Installed (PowerFC D-Jetro w/FC Datalogit). First Dyno Session complete and LOW Boost Tuning (turned down boost from 1.05 BAR down to 0.6 BAR) w/MAP build from scratch.

    Car peaked out @ 300 WHP / 260 ft.lbs of TQ. Tuner pulled timing and richened it up a bit till next tuning session. End result, a SAFE 297 WHP 231 ft.lbs TQ on 0.6 BAR of Boost. Only lost 30 ft.lbs and 40 WHP with nearly 8 lbs LESS boost.

    Next session (late July 2008 Possibly) will be tune for 1.05 BAR of Boost.

        Cool idea JD74.

        Wingnut's post should be an example to follow. Great work!

        Let's get a bunch more, keep chitchat to build threads, and we'll probably end up stickying this.


        VEHICLE: 1989 GT-R
        ENGINE: RB26DETT, 88mm bore, CR=8.7:1
        MILEAGE: 127xxx Kms
        OIL/WATER PUMP: Nismo/OEM
        OILING SYSTEM: Tomei Orifice, Tomei pan baffle, Greddy oil cooler and filter relocation
        INJECTORS: 600cc Nismo
        FUEL SYSTEM: Bosche 044 in-tank
        TURBO SETUP: twin GT2860R-5
        MAP or MAF's: MAP
        INTAKE SETUP: HKS hardpipes with Apexi Power intake
        INTERCOOLER: HKS aftermarket
        VALVETRAIN: JUN 264/264 9.7 mm lift - adjustable gears - Now degreed - intake was off 3, exhaust 10
        HEAD WORK: Intake mildly ported and left rough, exhaust opened up about 15% and polished, combustion chamber polished
        EXHAUST: HKS dumps, Tomei DP, 85 mm HKS Priest
        BOOST LEVEL: 1.2 bar = 17 psi - Blitz Dual SBC Type R
        ECU SETUP: ViPEC Speed Density
        CLUTCH: ORC series 700 twin
        COOLING: Greddy aluminum rad with electric fan

        Note linear torque increase from a respectable 150 ft.lbs @ 2500 to a slingshot-like 325 ft.lbs @4300 rpm, relatively flat plateau to about 6500 rpm and only modest drop in torque up to 7500. This is without any cam timing tweaks and with everything pretty darn warm.

        The car feels very alive on the road and willing to rev til you shift. :drive:

        Nice conservative tune intended to let me have a ton of fun without making rebuilds my hobby.
        HP: 390 RWHP
        TQ: 330

        Boost 17.5 psi
        HP: 525 AWHP
        Tq: 425

        I thought it was fast before....

        Updated dyno chart below. Torque comes on earlier, stronger, and falls off less. Power was still climbing at 7500 rpm where we quit.

        Old dyno chart for comparison.

                    The thread title is engine mods. It would make some sense to add power train, because that's part of how the power gets to the road. Suspension would also fit that category. Let's keep focussed on power train with suspension details.

                    The main reason not to get into non-performance mod description is to keep the thread clean.
