Hi all I bought a coupe and "apparently" it has a hybrid turbo on her, and on top of that I found two turbos in the boot how do I tell what has been done to the turbos
If the turbos still have stock compressor housings then usually the only way is to open them up.
Remove the compressor cover and measure the diameters of compressor's inducer and exducer (the inner and outer diameters). Tell me what they are and I'll calculate the trim for you.
