alright........... let's update.
ok, bought a smallish intercooler to keep the stealth look.

there is room to go bigger if i want but for now it is looking ok. intercooler "installed"

all is well so i purchase a silvia aluminium radiator, 40mm thick triple pass. sweet.

looks good.........
from that angle. have a look at this

the crazy angle is caused by the drain plug fowling on the chassis rail. do i need the drain plug? i am about to cut it off.
heres the drain plug

and in place...(please excuse the hack angle grinder job down there)

ok, so next step is to cut off the drain plug and the radiator cap. and get it blanked with a TIG. ill then drill and tig overflow into the side of the radiator and run it to an overflow tank with the radiator cap attached.
either that or ill just drop a hole saw through the bonnet [88]
more cutting required to get the intercooler and radiator even further forward. then its mount gbox time. booyeah
