I wish I could remember exactly as I was originally to provide the engine and use a JWT ECU or SAFC to tune.
Justin suggested a front mount with an AEM system and he was going to get an engine from his supplier because he wanted to be confident in what he was working with.
I believe it was around 5g’s but just give him a call and ask him about the set-up he had in mind for James’ G20. You can go a much cheaper route using the existing ECU, but Justin doesn’t like to do anything half-assed. Both his S14 and his drift car are evidence of this!
