Well i fitted the larger laminova today and after some swearing at the hit and miss AN10 fittings that sealed fine before and wont now i managed to get it to seal properly. Remade the joint about 5 times and was about to give up when it stopped leaking on the last attempt.
First impressions are that idle pressures are unchanged and on the low side. 14psi at 800rpm but with aircon on they can bump up to 17psi with just 100rpm idle speed difference. Straight away thou i noticed that at 3000rpm i was hitting 85psi much easier and quicker compared to the medium sized cooler. During the vtec crossover oil pressure now stays into the high 70's and sometimes hits 80psi. On my last tuesday on track i was lucky to get 70psi once the oil had warmed up.
IMO i would not fit anything other than the larger cooler on the S2000. My testing shows that the medium sized cooler restricts oil flow alot and in the longterm this cant be a good thing. The larger cooler is designed to handle flows larger than 60 litres per minute where as the medium one only can handle 40 litres and then starts becoming a quite big restriction to oil flow.
Ignore the cable ties they are temporary until i make some brackets, just incase anyone is interest the cooler is mounted on a 15mm foam which stops any of the oil pump pulses being pushed through the chassis and into the cabin. If you have ever rigidly fitted a air to oil cooler then you will know what im on about! It also lifts the cooler above the chassis rail edges on the front cross member. Steel rubbing against aluminium wouldnt be a good idea!
There is more than enough room to fit the larger cooler, its abit close to the AC lines on a RHD car but nothing that cant be overcome with some clever placement.
The OEM cooler plate uses 13mm ID water hose so you need some hose and a 16mm to 13mm silicon reducer on each side of the laminova. Luckily i managed to get some 90 degree angles with the reducer built in which saved making more joints.

I am thinking about upgrading my S2000 with a laminova heat exchanger.
What model is this exactly? C43 largest version?
Will it fit into an OEM S2000 with the original air filter box?
Laminova says: "Coolant flowrates > 80 l/min: No restrictor is normally needed. Coolant flowrates < 80 l/min: A plug or a restrictor can be used."
Does anybody know the coolant flow rate of the S2000?
Did you use any restrictors?
Thank you for your help.

You need the larger cooler, if you use the smaller one it will result in massive pressure drop during vtec. The larger one is fine and you get oil pressures almost the same as if it wasnt fitted.
Mounting is down to the individual, running the oil lines will be a problem with the factory airbox. As for coolant flow rates the oil pump flows nearly 60 litres a minute at 6000rpm. Im sure that i read that the coolant pump flows nearly 150litres a minute at 6000rpm but you have to think in my case that the laminova is not fitted directly in the flow of the main coolant. The flow the manual talks about is in the main radiator hoses which is quite a big diameter. I opted for the restrictor that causes the vast majority of the flow to go around the outside of the laminova.
Im sure you could do a very good job of mounting one with time but you also have to consider the AN10 hose lengths and the bending radius of the hose. In my case mounting it on the cross member seemed the best solution.
