I have a 15TD 4ec1 Isuzu engine on a corsa b with a failing turbo. Should I go for the same model RHB3 or for the RHB4. I would like if someone can give me at when the turbo opens and close for both including the pros and cons.


Thanks

what you could do is go for the same turbo but then use google and search for the turbo boost modification which about doubles the power of your turbo and give the car alot more get up and go

thanks mate for the info. As I have an RHB4 at hand at the moment. I heard it is direct fitment as I also have the manifold to engine. I think that the RHB4 takes a little longer to open and keeps on spooling more than the RHB3. The reason that I don't want to boost an RHB3 is that I am using it for everyday use.

ah right ok, i dont really know alot about the vauxhall diesel turbos to be honest. and i dont think anyone on this site would reeeeeeeeli know about it either as we're mainly petrol based.

Yes I noticed that they are more on petrol but here in Malta we are obsessed with diesel performance lol
