Again, an issue is if the injectors are boost side, you will need boost pressure+fuel pressure to keep the same fuel pressure relative to the injectors. A special boost referenced regulator is required.
The thing is, I've always planned on using a secondary fuel pump for this project anyways. It will be an either an in-line deal that will be controlled directly with the Megasquirt (MS) system or seperate from the stock fuel system all together just using the MS system. The stock fuel system will therefore be untouched in the latter matter. I forgot too, the MS system reads 2 bars...Good news for the project.

The only thing with using the TBI system...Well, I could still use that system I guess...

By the way, I would love to just hack the stock ECM and forget about the expense of a MS system and all, but as of now, the only person willing to help with that needs my car in-garage (yeah, like that's going to happen) somewhere far from my state. I have priced an EPROM reader/burner and EPROM programmer for this but it will cost near $1000.00 extra than I have right now.
