I am planning to build a race car engine for my 280zx endurance Chumpcar racer. It's all amateur hobby racing and nothing professional, still it would suck very much if it breaks during a race. I am doing this 50% for power and 50% for reliability. I am a beginner hobby mechanic.
I got all the OHC Nissan books
- 100% for 10hours without blowing up several times a year.
- Usable range 3500 - 7000 RPM (To keep cost down and keep some reliability)
- 200HP crank (but 250 would be fantastic)
Engine will consist of the following:
- Megasquirt fuel only (can't do timing due to race regulations)
- Race camshaft (Schneider 284-92F is a good candidate, 284/292 (236/244 @ 0.05"). 488/.504 lift)
- MSA Headers
- F54 block
- N47 head (worth spending $650 for a Lonewolf porting?)
- Some exhaust (2"?)
I have a F54 block that comes with pistons but no head. This is what I plan to do:
1. Replace piston rings
2. Replace main and rod bearings
3. Replace all gaskets
4. New waterpump
5. New oilpump
6. New cam springs
7. New rocker arms
8. Should I get new pistons (block comes with pistons)?
9. Should I get a new Timing kit?
Is there anything I should add to my todo list?
Does the cam make sense?
Is there something that is specially hard that I should leave to a professional? First time I ever mess with engine internals.
I am not super tight on budget but forged pistons is way out of my budget.
