Twins are not for the faint hearted- it did take some fab work and yes you do need to account for extra pipework, oil lines, filters etc but it wasnt too difficult.
For me it was a learning experience, what can a HKS turbo kit from Japan in the mid 80s achieve, I havent turned up the boost yet but I'm very impressed with how the power is delivered and how she drives. I've also got a set of HKS ITBs, with a HKS surge tank that will go on next to compliment the HKS theme.
I'm writting from an iPad at the moment so not easy to attach pics, I'll add some when the ITBs go on.
