Hello. New to this forum but on many others. Long time car builder having built an S14 silvia using a RHD clip back in 2002. Hard to believe that was 17 years ago!!

Current project is the worlds greatest Z31 with a naturally aspirated RB, an R30 Skyline that is at the port now waiting to go on a boat, a 95 D21 Nissan Hardbody that I did an 87 Pathfinder front end swap and a full Weistec built Mercedes E55 AMG.

The Z31 is the main project that I started in October of 17. I picked up a super clean 56k mile 86 300zx. I also picked up an N/A Rb25 that I immediately tore down. NOS RB26dett head that has been fully modified. Custom machined combustion chamber with massive Superrich valves, Tomei beryllium copper seats, Supertech guides, Supertech dual springs, Ti retainers, Tomei cams, Tomei gears, full port and polish, RB26 ITB’s sent off to EFI Hardware in AUS for larger butterflies to 49mm, new seals and all fresh cad plated hardware. The block was bored to 87mm and the head stud holes enlarged to accept the 26 head. Custom made 11.6:1 CP pistons that were created using a 3D scan of the combustion mold. The pistons were then WPC treated and the domes ceramic coated. Nitto 77.7mm 2.9L stroker crank and Nitto H beam rods.

The suspension upgrades include an S14 rear subframe swap, Parts Shop Max adjustable arms and drop knuckles, Feal coilovers, Cusco strut towers and sway bars. Wheels are RS Watanabe.

Body work includes shaving the side markers, trim and antenna. The front has been converted to Kouki, JDM carbon front lip and the rear Kouki bumper will be shaved and shortened.

Dapper sequential LED tail lights, JDM fender markers.

Interior is stock other than brand new carpet, real JDM Bride gradient seats with carbon kevlar backs and a Renown steering wheel.

The overall goal will be my restomod version of an S30 Z432 only in a Z31 and painted 920 Nissan Safari gold.

Engine bay has been fully shaved and all seams stitch welded. Should be a beast with 300 rwhp and 10k redline.

Here is the vision render.
