hi have been building a 2.5 type r for the last 2 years
lookin for advice fitted 20g turbo and gettin it remaped just wondering
whats the best injectors to go for thanks ihave also upraterd pump

 

I would say at least 550 but the bigger the better really. If you go for 550 you could end up running them at say 80 percent but if you went 700 then you would only be running them at say 60 percent which is better for the injectors and will then make them last. Also bigger means if you end up looking for more power in the future you will not have to sell out for bigger injectors all over again..

 

i saw the other day a 2.5 fitted to a sti v2 running standard 380cc injectors, it had been mapped but will have to see how well it goes.

 

To make sure you have enough fuelling available for the 370-400bhp potential of the 20g, then I'd defo fit 740cc ones.

550s will probably be a bit marginal...

 

thanks for all your help gr8
