hello buddy
for you any G series will be a good idea
i have done G15A /G13b
currently i have 4efte in my car
and client car is running D15 turbo setup
any honda setup is recommanded for project not a daily runner
4efe/4efte/7afe G15/G16 are happy engines and can be used as daily runners
if you want perfect match then K6 manual is best option for power and economy
4efte/D15 /5afe /D16/G15/G16 they are need same level of work and same level of budget ....
where as K6a is cheaper but work is same as any other engine
Regards
