don't you have a 185 ata?
what upgrade is the cs/rc rad? jus get a golpher alu rad of ebay.
fit a fuel cut defender for 330 at the fly.

..no feckin way. your be maxing the injectors at least even with 540's fitted and the fuel maps will be way way off. (and besides your need another ecu to run different injectors.)
how are you goin to optimise the afr's and tvis on the rollin road? piggy back or stand alone ecu? why would you need the fcd if your going this route?
1. metal headgasket upgrade
2. intake upgrade and sparky plugs
3. exhaust (including de-cat pipe) 2.5" should do
4. 205 charge cooler or front mount intercooler
5. 205 tubby or bigger
6. stand alone ecu and bigger injectors
7. mapping.
and jus for fun

8. blown ringlands

9. full rebuild with forgies
10. tvis removed
11. 205 intake cam or pair of bigger cams
12. remap...lol
