So I was thinking somewhere along the line that since I still have the long block from my 7AFE and the 4age. Im planning to turn the 20V head and mate it onto the 7afe block and make a 20V 1.8L Hybrid engine. 7AGE 20V turbo. Dyno #'s are unknown and im not sure if its even possible, but considering the fact that 4age 20V internals are hard to come by, if not even next to an rich $$$ impossible. So if I do plan to do this, I need a good daily driver car and some funds, but when I have both Im gonna attempt this and see what turns out.
--------------------------
1.) Heres my plans, forged turbo pistons of 1.8L.
+ Using the 1.8 block I can find many support and hardware that will fit this American Block.
+ I get to keep A/C, P/S on the old 7afe engine.
- Using the 1.8L, I will lose those high revving power of the 4age block, but will compensate it with the turbo.
The 1.8L is more of a block made for combustion and not performance, so the Turbo will use it as a power house for HP figures.
------------------------------
2.) 4AGE 20V head, Using Toda's website I can find the short block parts elimanating the need to search for the long block internal parts.
+ 20V head, 3 Valve intake and 2 exhaust. Elimante VVT with cam shaft that will cover the 3rd valve when VVT opens. So I get 3 constant valves and VVT running during the whole operation.
- Timing belt issue, oil issue, what am I gonna do for spark?
----------------------------
3.) Megasquirt EMS, something cheap yet something that will work with the hybrid systems.
+ can be tuned, cheap and effective
+ Spark could be Ford EDIS system.
- hard to build, and no support on hyrbid issues.
- Ford Edis, will provide many failures, or trials and errors.
----------------------------
4.) Turbo system,
+ More power for the combustion of 1.8L
- Must build my own header that will support the 20V head for turbo apps.
----------------------------
5.) Time, wat am I gonna do?? Im in school and must also work!

-------------
What do you guys think? Is it possible. I have the two engines now and when I can find someone who is willing to sell me a complete 7afe engine with everything still attached to it. I will begin my experiment.
But if I can find a daily driver now, I will take out the 4age and see if it will work with the 7afe block.
