Main engine specs as below..
Brand new 200 block with new Cosworth pistons and Farndon rods. 8.5 to 1 comp ratio. Standard crank. Ported/polished 4wd head with Kent CW7 solid cams and solid lifters. New valves. WRC spec head gasket. ARP head stud kit.
Garrett GTX3076 turbo on a Peter G tubular exhaust manifold. Swedish intake plenum with a 77mm throttle body. The engine runs on ethanol fuel and has a fuel system made to suit including 1500cc injectors.
The engine uses a MoTec M400 ecu.
Any thoughts on expected power on these specs would be much appreciated.
Cheers,
Gav
Sounds like it will have plenty of power with that specc, 1500cc injectors are the biggest I have heard of on a YB, mine are 890cc and chuck in loads of fuel. MPG is obviously not a priority. What State in Australia are you in as I know the rules on modifying cars varies from State to State. Is it going to be a track car or road car? If a road car you should suprise most Aussie performance cars for sure!!
