what have you done with stock FI and performance mods?, quest for a killer D-jet 2056cc motor Options

[realred914]

what are the trick mods for performance power when building a D-jet motor . it is a tired 2 liter that will be getting a big bore 2056 piston kit.

what are recommendations for valves, porting compresion , etc....

will be a driver car 91 octane gas, , have SS heater exchanger, and I do want heat.

what can be done during rebuild to beef up the power????

My recommendation is
Raby cam and lifters-(9950 or ?)
Porsche swivel feet
CR 9 to 1
tight Deck ht 0.40
42x36 valves w/HD springs
Raby new 914 2.0l heads
balanced everything


115-120hp with Djet and SSI HE's

thanks for the info, what is done to a raby head? i got my stock 2 liter heads and plan to rework them with new seats and weld any cracks. does a raby head have additional work done on it?, if so what?

First of all we don't rebuild any OE castings, the majority should have been disposed of 25 years ago. All heads that we offer are based on NEW castings.

For details on what separates our cylinder head program from the rest, follow this link, then each head offering- I even have flow charts for all the offerings.

Or if you want to just build the best stock FI 2056 you could just buy my full engine kit that has heads and the entire combination as well as all machine and balance work complete.

No technical info on parts selection was found on these powerpoint presentations.

i am looking for specific things to do on a 2056 engine. I am told i have to pick the compression , valves sizes and such first, before ording a cam.

I am looking for direction in picking these things as I have not purchased anything except main bearings at this point, so I am open to all the options

I t would be nice to have some suggested parts list that would be compatable with the correct cam and such, thats what i am looking for.

anyone?
