Hi there,
I'm currently rebuilding my 1990 740T (B230ft) and as things tend to do, it has become a lot more involved than expected. One of which is the fact that the turbo appears to be too far gone to be rebuild-able. As you may know, the TD04-13C turbos are hard to source and are expensive. I remember a few years ago seeing an ECU upgrade for turbo red-blocks on IPD's website and was looking for it as I've now come across your posts here on turbobricks. If possible, I'd like to modestly upgrade my turbo but know that I may not be able to be successful with my stock LH 2.4 system. I am quite familiar with tuning standalone ecus as I've been playing with my turbo charged Miata for many years. My Volvo is my daily driver, so I don't want it to be too crazy but am very interested in what you have to offer. I just got my stock injectors flow-matched so hopefully I can stay with them. Your post has blown-up to 80+ pages now so it isn't feasible to sift through it all to figure out if you can for sure help me or not. Please let me know your opinion as to where to go from here.
Thank you SO much!
What planet are you from where a 13c is expensive or hard to source?
The "modest" upgraded turbo is a 15g typically from a FWD car. You'll be fine with stock lh2.4 & it's standard injectors until you start turning the boost way up or you have a special need for aftermarket EMS. Also if it's your daily stay with lh2.4 but if you already have experience with a standalone, you do you
