Was wondering if you tackled anything like this before. Got an F54 with the p90 head 280zx. Wanting to go with the ka24e piston, the 9mm 240z rods, stay with my l28 crank, and go with the 2mm head gasket to lower compression. with my calculations which correct me if Im wrong here would make for a 3liter engine with 8.00:1 compression. At the same time I would want to flow the head but not trim in down shorter. I was also wanting to bump up the fuel injectors to a larger size and go with an aftermarket header and header. currently the car is an NA motor but has a flow master exhaust and cold air intake which I believe will not have to be changed out. what sort of price am I looking at if I leave the car with you as well as if I just bring you the motor. Currently I have 320k miles on the motor so I would also want the bottom end gone through balance the crank and polish it and all new bearings. I was also thinking on going with a stage 1 or stage 2 cam it is a daily driver so I would like your opinion on this. Im also aware that a may have to go with a custom ecu to leave it fuel injected. Thank you for letting me know.
