I just picked up my 93 with a newly installed b230 fd. I had always planned to do this myself, but the original engine was done, and with 2 young kids and a house that needs a lot of work I just did not have the time. I was just going to get another b230 put in, but the shop had this b230fd with only about 30000 miles on it.

So now its in the car and it is working fairly well. I am wondering how much it should boost. I have the 240 turbo boost gauge from my dead 240 turbo and the boost on this new engine cuts off about halfway into the yellow range. Thats roughly 7 to 8 psi. Is that normal? My old b21ft cut off just at the red zone, around 11 psi.

It is using the original computer with the yellow injectors so I may have fuel delivery issues at high boost but it does not feel like I am running out of fuel. It feels like the wastgate opening.

Its going to be a nice engine. Much easier than the old b21ft. It has a water cooled oil cooler so you don't need the hoses and the extra rad to cool the oil. I puts the oil filter in a much easier spot to get at as well.
