Hello World,
Has anyone successfully been able to pair(dial in) a modified 914 L-jet system with a 2200 or 2258?
I am looking into doing this for my street car and am aware that the AFM will need to be modified. I have a 52mm throttle body with a modified throttle actuator so the operating arm will work with the L-jet and will fit the stock plenum seal.
Will I need bigger fuel injectors than my new 2.0 injectors? If so, which ones?
What else do I need?
I did a Google search using key words, but was not able to find any previous threads on this topic.
Any advice or thoughts would be appreciated.

What's your budget?

You'll start running into cost benefit tradeoffs with larger displacements in a type 4 above 2 liters. Just saying and yes from experience.

I've seen short stroke 2.0 type IV's with L-Jet just smoke the tires on a 914...big bore short stroke engines just pushing the limits of their VE's.

To get that same efficiency in a type IV above 2 liters will take more dollars on a log log curve above 2 liters.


Good luck....anything is possible.

It seems like the 2258/2270 is the sweet spot for a bunch of different reasons.
Piston size is staying within reason at 96mm, so the jugs are not super thin. You can still have a well cooled engine with cast cylinders. 2258 is a combo that I'm getting more familiar with (seeing that I am now driving one).
