Im gauging interest on the last motor I built myself. Its a S5 6 port engine, big SP intake, race ported exhaust(no sleeves). Full spec list to follow. The motor currently has 11K miles, and is running extremely strong.



> Its a S5 n/a block

>

> Inside the block:

> - hardened stat gears, grooved for type 2 main bearings, installed.

> - ecc shaft oil jets modified for more flow

> - TII oil pump and FD rear pressure regulator. Peak oil pressure is

around

> 110 PSI.

> - competition thrust bearings

> - atkins apex seals

> - teflon coolant seals and viton oil seals throughout

> - everything was blueprinted

>

> intake porting:

> - very large SP on the primary ports, large SP on the secondary and

> auxillary ports

> - auxillary port runners have a nylon insert to smoothly direct flow into

> the chambers. 6 port sleeves are not needed, not will they work.

>

> exhaust porting:

> - sleeve removed, race ported exhaust.

>

> misc:

> - shoulder around spark plugs ground off to allow use of shorter plugs

> without needing a narrow wall spark plug socked.

> - The spark plugs are currently all 9's. Anything hotter results in short lived plugs, and a loss in power.

> - oil feed on front iron tapped, for running a turbo. The thread is 1/4"

> NPT.

> - the coolant feed on the rear iron is also tapped 1/4" NPT. If it is

> necessary to run the BAC valve, or you have not done the TB mod, you will

> need to put a nipple in place of the plug to run the coolant line to.
