What kind of pistons and compression ratio are you planning to use?
And what about the fuel system? I know for sure that there are few people here who are interested in converting the single point fuel injection on their E15 Galant turbos to a multi point injection and manifold.....
Well, that´s what I´m doing in a way, or the other way around, you might say. I have a the 4G63T engine from a galant -86 with a compression ratio at 7,6 it also has the oil cooling under the pistons.
I use my cars stock multi point injection system with 4 extra injectors controlled by pressure swithes. I have tested this concept for several years in diffrent versions and I can strongly recomend it.
My first turbo conversion was on a -87 Galant with the 2.4 litre engine. I left the multipoint injection system in the car and mounted an -85 4G63T-engine instead of the 2.4. I also mounted an intercooler from a saab 9000. This works very well if you run about the same turbo pressure as in the stock 4G63T -85. With the IC you can run higher with out having to worry too.
That concept is not so complicated to do yourself. The engine I´m running now is a bit more complicated, but the "inside" of the engine is the same as the mid-eighties mitsubishi turbos.
Last summer I had 1.8 bar in turbopressure for a while, and the only thing that broke (that time :-/) was the intercooler from an saab aero. If you look up in the sky a cloud free night you might still see pieces of it in orbit. Well thats it for this time folks, it´s friday afternoon and soon it's partytime. If you have some questions don´t hesitate to ask, either here or on our new forum in sweden.
