£250 for a second hand kit.
(largest possible) water cooler on the front, hoses from front to back, a water reservior, and a big pump. 
it gets heat soaked, because the stock pump stops whan you idle. there is not enough water in the system and the water cooler is too small. Once your water gets hot, is can't really cool down anymore...but they had about 6x the times of the water cooler 
You need a full sizes LARGE water cooler in the front. And if you want to go to the track or drag race it, you can even drop some ice to the water tank, and your intake air will be cooler then the air outside! No air to air cooler can offer that, ever! As a rule of thumb you want around 20l/min of water. Probably the easiest way to do this is to use a shurflo pump, only trouble is you'll have to run slightly higher water pressures (around 1bar). Alternatively buy a st205 second hand kit. As the water in the system heats up the water will find a natural operating temperature dependant on the size of the pre-rad and its rate of heat transfer to the open air. This will be dependant on environmental conditions as well as the pump speed, layout of fins etc. Its safe to assume that the heat loss from the reservoir is minimal compared to the pre-rad so its size will not really aid cooling. Therfore the reservoir serves no real cooling benefit. However that said it will take longer for the water to heat up using a large reservoir. This could be beneficial for the odd drag run. Keeping the water as cool as possible until the actual run. This can be wired in on a bespoke system though by simply tapping into the throttle position sensor, and using its output voltages. with mods i currently have. Can you not configure the st205 CC to run all the time? or is it not worth it?[quote="Jimbob"]Your looking at £250 for a second hand kit. I'm also running a minimum of 1.5bar. It's all fully documented with pictures, too....original rad boot mounted, two whackin fans, although you only need one, and a pump from a caravan. And does it stay cold - you bet it does, stone cold! And it has no problem with 1.4 bar. Ive removed the swirl pot cos you dont need it - and ive removed the water resavoir cos you dont need that either. The porrf of the pudding is sitting in the drive...as they say! I piped mine up with half inch copper then lagged it - nightmare job but brilliant once finished., more of the charge cooler pump dont last long if use constantlySFLee wrote:the problem I am looking is the pump

1.2 bar? Not sure how good the st205 one is can't be much more than that? Dunno try the GT4OC[/quote
In terms of flow and pressure drop, from my calculations, the ST205CC should be WAY better!
I'm just putting the finishing touches to my ST205CC install, and I'll be logging both coolant and air temps, before and after the CC, so no one will be able to dispute the results.
When I'm done, I'll write a list of things I did and parts needed.
can't wait for this to happen.
The air to air brigade don't mention that much, oddly enough

It's used every day too. 9 runs down the pod in june proved it doesn't heat soak as my 8th run was my quickest and i didn't turn the car off between runs either. As allan said really, all you need is pipe, the celica throttle body isn't essential, but it does make it a neater job, a pump of some sort and the cinquecento rad. It doesn't have to be this rad, you might find something that fits better, but after god know how much research, this is the one i found to fit the requirements best without resorting to a custom one. I used 1" clear pvc pipe, smaller would be easier if you still have the aircon though as i've removed mine and the pipes now run where the ac pipes used to be.
