I have a 93 FD with an apexi, sports cat, 3inch system, sports air filters, std map.battery still in front.
I am just about to pull the rad out to fit a replacement fan after the river side fan burn out after my last track day.
Given the rad is 24 years old it seemed sensible to replace it before it fails and it will help with future track days I think. I know Koyo are popular but would prefer to buy British - are these any good - http://radtec.co.uk/products/283/RX7-Radiator.htm
Replacing the rad reminded of v mounts which, when combined with a tax rebate, woke the sleeping 'MustMod' monster.. so.. is a v mount necessary if running remapped twins?
If I mod then I will need a new downpipe with the remap, any recommendations?
Will this increase exhaust noise?? I run 97db @5000 rpm so I am close to track day limits and on track is where i want to stay.
Then there is the part of me that has left the car largely standard that questions whether the remap is worth the inevitable engine ware - is a 10% power gain that noticeable anyway..? I know I cant drive the car to its limits, so making it faster will only increase my error margin.. (SHUT UP! says MustMod) ..
Advice, thoughts and meanderings most welcome
