Kinda, the TD04 is very similar to the VF-11, however it probably has better flow and a higher PSI rating (?). Basically, it was newer in design and manufacture....and there are a lot of cheap ones out there should this one kick the bucket.
The boost is still below 10psi with all tuning/mgmt at stock. According to everything on the internet, injector upgrades are not required until the mid-teens PSI. There is a built-in fuel cut that should kick in at around 14psi that needs to be circumvented if running a MBC approaching that number. I would like to upgrade the fuel pump at some point just to refresh the old one since it's not an expensive mod.
I am planning on running in this config or maybe up to 12psi for a while, so no engine management for me. There is somebody selling a ECU upgrade that basically is plug and play and is theoretically mapped for either mild upgrades like mine or more. I'm not so sure that generic mapping is a good idea, and also I do not know if the ECU retains the ability to learn with that plug-in. I cannot afford the pricey standalone management out there, and frankly on a car this old I'm not sure it's the best idea unless I want to do a lot of wiring. I'll slowly research it however while I work on suspension.
