The Heart of the four banger, a couple may know the engine, yes it has become a celebrity quickly since it graced our shores
,
The tear down began but before I go further a run down of what I could see from the top of my head. Car has no ECU and no coilpacks, I am looking at either a Power FC / Vipec / AEM setup for it when the time comes, harness is butchered (already located a replacement harness, thanks Brian), Splitfires already located as well. Engine has Sard 700CC injectors, what seems to be a Tomei Fuel Rail with braided lines, huge HKS Fuel Pressure Regulator (size of a Walbro Pump), Upgraded Individual Throttle Bodies, Extended Sump, what seems to be an HKS T51S turbo setup, HKS bottom mounted cast iron manifold, big HKS external wastegate.
Looking at the block we can see yes the famous 24U and not the standard 5U, so yes this is an N1 block so far, internals will be checked when I drop the sump hopefully weekend. Cam covers were removed and WTF N1 custom cams, what is that engraved 272 9.7 IN and EX
, oh it gets better, removed the ITB setup and I am looking at a match ported intake plenum to throttle bodies to adapter plate to head, the port work is spectacular, and when I look inside the port I can see what looks like brand spankin new bronze guides and no doubt probably upgraded valves. Looking under the cams you can see the area in the head machined to accept the bigger cam lobes, not sure if standard but the RB25 head I have does not have this machine work as standard so I am thinking it was done, the springs for these cams will no doubt be upgraded and more than likely the buckets and shim as well. There are also adjustable cam gears as well.
I will be giving the engine a total refresh with gaskets and seals and cleaning the entire exterior, not removing the head and black at all but just neatening the exterior. Will be ordering a full gasket / seal kit and definitely a replacement silicone hose set for the entire engine as the current hose are in a mess. The clutch seems to be either a twin OS or triple and the gearbox seems to have been opened, maybe to upgrade the stock gears with some upgrade but not going to speculate. The entire rear suspension is fitted with Nismo arms and was told that the diff is too upgraded to either a Nismo or Cusco, so the front diff too may be an upgrade. A couple more snaps but updates will follow soon enough as parts come in, will take some time but should come out half decent at some point. Must say thanks to Navin from D&D for the engine!!!
