It's a GT28RS (I'd put on a more up to date G25-550 or Borg Warner EFR 6528 if I were building it today). Intake manifold is custom CNCed and tig welded, and the fuel rail is likewise custom. Turbo manifold is a basic cast log manifold. Engine management (both spark and fuel) is done with a megasquirt 3. Intercooler is a custom core designed to fit behind the spider front bumper- a GTV would probably demand an air/water intercooler due to packaging constraints. I can't claim credit for the base turbo build- I bought the car from A. Georgi on the forum who is responsible for the getting the turbo running.What are the specs for your built motor? Any head porting? Can you remind us what turbo you're running and your induction?
Head was a bone stock Bosch 2 Liter (no VVT) with stock cams. For version 2.0, I'm having a head built with 1mm oversized valves, some porting/bowl shaping, and some street performance cams. Turbos don't really need head work to make power, but I'm hoping the head work will outweigh the off-boost power loss from bumping down the compression to 8.5:1 and help with spool. Unfortunately, the head work is the main thing holding up the project. It was supposed to be done at the end of last summer, but my head builder had some health problems and other setbacks. I'm also having the chassis painted while the motor is out.
Bottom end for 2.0 will have JE Pistons (8.5:1 compression), O-ringed Darton liners (sold by Wes Ingram), Carillo H Beam Rods, balanced crank, windage tray, Gordon Raymond oil pump, Alfaholics "Rally" billet flywheel and clutch.
