I run jenvey throttle bodys on my 3dr cossie with a modded manifold for als and a plenium i made at work.The complete in let kit from jenvey cost about a 1100 notes that includes 2 fuel rails to run 8 inj and all the bolts linkages cables and so on. i have 48mm throttles and the plenium is made with a f1 hart 415t design in mind and they made 999hp on the dyno way back so the design is tryed and tested and it can work out alot cheaper than some of the other options. There is a spacer that you can put in a std cossie inlet which can be used to gain another 30 hp so ive been told.
