Inliners International Forums General Discussion Engines 292 engine build advice needed

Ok a few comments:

1) unless you plan on running sequential fuel injection later MS3 is overkill. MS2 with extra code will do fine for what you want to do. If you decide to run sequential now check Tom Lowe's thread on his turbo 292 - the 292 intake ports need to have dividers installed to do sequential. The TBI could be used as a throttle body for seq. injection if you remove and block the resulting hole where the fuel comes in. This would give you the needed TPS signal. You will need to run a BBC TBI to get enough fuel and boost reference the regulator if you run boost. Use a TPI type pump.

2) if you keep the boost low (8 psi or so) AND tune carefully then you can run the cast pistons BUT you must keep the engine out of detonation. 9:1 is fine even with boost.

3) which ever way you go do make the change to fix the quench problem - 0 deck the block and run the mls gasket(check piston to valve clearance first..).

4)MS can do boost retard - and activate a water/methanol injection kit under boost.

Too bad you didn't stop here earlier. There are other options that are less costly than rebuilding 60's vintage engines, that make 275/290 HP in stock form for $2000 to $2300 complete with 4sp OD transmission. But you have already spent your money.
