After a load of research and a quick chat with Red16 from passion ford.
Have conculded the best option would be......... RX7 FC3S 16" fan Civic Rad 92-00 Pics from Red16's build    My only real worry is the fact that the civic rad might not be able to handle the load form the RB25DET. Not sure what i can do apart from possibly install a 2nd radiator somewhere or two oilcoolers to help bring down the temps a little.

I would of thought the rad is never going to get cool air mounted like that, you may need to duct air into and out of it. Neat looking rads though

The celica gt4 (94/99) charge cooler can handle a good amount of power for its size, its a common upgrade on the mr2s when you start going towards the 400bhp mark
Just means another rad and water circuit though

When using a ST205 GT4 water/air charge cooler (or any higher BHP charge cooler) you need quite a big radiator to get them working properly, like smal car size... A lot of the MR2 swaps use a Rover Metro radiator! plus there's the extra plumbing/complexity to consider
... For simpicity's sake a nomal air/air intercool would be the way to go. Top mount may be an option if you don't mind having a big bonnet scoop. The later 3S-GTE's in the ST215 went back to using air/air topmounts

But there must be reason why top mount air/air intercoolers are often called "interwarmers" - especially in car like Roadster, which rather don't go at high speeds, because of aerodynamics.
So - I think water/air intercooler could be very good way - small and efficient.

Big thanks to Skov for the great price on the fuel sender. If anyone wants a standard 1.6 mk1 mx5 fuel pump give me a shout!
As you can see a nice Walbro 255lph RX7 GSS342 33911-3 fuel pump. All i need now is the plug for the sender lol
