If you want to do it cheap, do like my friend. Shave of 1,5mm on piston, He has been running like this a few years, 223hp with a tb28 turbo. Or leave it stock, and boost 0,4 bar.
You have unstable ignition signal, or too strong for the ecu. We often see this, then we absorbe(not sure it is the right word).some of the signal. Around 100kohm on the signal
Haha mabey, i didnt think of that when i built my 5e, just took som stock 5e, but friend told me, when he wanted to order, they told him, they had different numbers
20% power loss of 243hp, will be 194,4 hp. 20% is too much on frontwheel drive, when we have FWD on dyno, we can se the power loss, it is around 10-12%
If you are turboing your 4efe, then just use your 4efe mapsensor. Mail salg@turbomotor.dk about shipping or info. http://www.turbomotor.dk/contents/da/d11.html scroll down to mapconv
All standard ecu run very rich on full trothle, when you change the clock frekvenz, you raise the rewlimiter, and change the injector time. So when you change cams, you often want abit more rews, then afr is still on the good side . But tell me about you experince.
I did that on my old 4efe engine, just installed turbo kit, and 4efte injectors, and mapped it with mapconverter(35 pounds) It had 290000km on clock, ran it for almost 2 years
