Engine Spec

This is an early draft of what I expect the Slowtra's engine to be. This is Stage 1 btw.

Engine Assembly
Pistons: Ross custom forged.
Cylinder Head: Stock
Head Studs/Bolts: ARP
Conrods: Custom, steel forged. Supplier TBD
Crankshaft: Stock
Crankshaft Big End Bearings: TBD
Headgasket: Stock is MLS steel but not good enough for the boost & power level I'm aspiring so it'll be either the Fel-Pro Permatorque MLS or Ajusa 3 layer MLS. Might get both for R&D since these don't cost that much
Cylinder Head: Stock
Cams: Stock
Valves, Springs & Retainers: Stock

Turbocharger Assembly
Escargot: Borg Warner EFR 6255/6258 i.e. equivalent spec to Garrett GT2860/2871R/GT28RS except tricker and faster spooling. Details in upcoming post
Turbo Manifold, Downpipe and Exhaust: Tonnka
Turbo oil and water plumbing : AN fittings with braided hose
Wastegate: Check EFR Internal
BOV: Check EFR CRV (Compressor Recriculation Valve). No ricer spec sounding BOV please.
Boost Control: TBD

Cooling System
Oil cooler, sandwich adapter plate & fittings/plumbing: TBD
Intercooler: Garrett
Intercooler piping: Tonnka
Intercooler connection: Possibly Adel Wiggins if budget suffices else constant tension hose clamps
Water Injection System: AEM or Cooling Mist
Radiator: Koyo or Mishimoto Automotive
Thermostat: TBD
Hose Clamps: WRC spec constant tension hose clamps

Fuel System
Injectors: Deatschwerks 600cc
Fuel Pump: TBD. N16 runs similar config pump as the GC8 Impreza WRX
Fuel Pressure Regulator: Tomei
Fuel Rail: GT Auto
Stainless Braided Hoses with AN Fittings

Induction System
Throttle Body: Currently stock but who knows
Intake Manifold: Currently stock but who knows. The Golden Eagle prototype on Vios Turbo looks dangerously tempting.
Intake Manifold Spacer Kit: Outlaw Engineering
Airbox + Air Filter: ITG Maxogen if budget suffices else it'll be K&N

Engine Management
ECU: Haltech but then again Bro Mr Vios Turbo is now playing with Autronic. Tough call!
Wideband O2: TBD

ok I had a read of you spec list and I can see 1 problem
The N16 ECU has a lot of CAN-BUS incorpated into the car. I don't think you can just swap it just like that.I know in the UK the N16 Phase 2 (Face-lift model) you can't just swap it over. best thing to do is have a look at the gearbox too see if there is a speedometer sensor also have a look for a throttle cable. if it does not have a throttle cable good luck with the modification as its going to be hard

also the N16 Fuel Pump is the same as any other nissan fuel pump the S14 and the K11 uses the same
fuel pump and the N16 uses the same fuel pump too. get a Walboro 255 :-)

I have done a lot of research into the QG15DE as I own one but the engine is a waste of time.
it is sittin on my drive dead as the timeing chain gave up (common fault) SR20DE for me :-)

Bro,

Sorry to hear about your engine. All N16s in MY are Series 1 and use the a throttle cable with conventional wiring. Worse case it is not an issue to rewire the entire car complete with my own sensors :) Just takes more time and money.

Thanks for the info on fuel pump. My engine builder is getting one for me and it will probably be a Walbro.
