I am looking at going to a 3" exhaust and maybe an intercooler on a rd28t and then a dyno tune to get a bit more grunt. it is a 95 model so just mechanical pump. The question is will it be worth it or am I going off track. I have seen a couple of intercoolers that fit the rd28 but they are the air to air type and I think that won't be of much help in the bush when there is now decent airflow , I would think a water to air a better choice but just want to get some input as to weather I am off the track or it is worth the money and effort. Any guys that have tried this combo I would like to hear your thoughts. Cheers
