They are very clear that the cage does not meet FIA, NHRA, etc. safety regulations to qualify it as a safety device. Nils, does the Cusco cage you have meet safety regulations? It's also very nice to see someone dedicated to building what appears to be a very balanced car. I hope to one day follow the same path. What is your target power level?
Very good question.
Most of the modifications made to my car have little consideration towards power. The main focus is to have a "realistic" race car for 2+ hour road races. Alot of attention has been made towards cooling, braking, suspension and safety.
With that in mind, I wouldn't mind less hp for sustained and reliable power. For power adders I have a stock sr20det with intake, fmic, dp, bc, walbro fp, exhaust... basically a "BPU" silvia. How much power would that make at 1bar? 250rwhp? 270rwhp? I have no Idea. I do plan on dynoing the car after I set it up, just out of pure curiousity.
To be honest with you, I am not sure if my Cusco cage meets any regulations. It was a impulse buy, based on availability and price. It feels very solid eventhough it is only bolted down, I definitly plan on welding the cage to the car and adding more crossmembers to it.
take care,nils
~edit: I do want to add though that I have seen tension bars and guages in other cars and the Cusco cage I got is alot beefier adn is not adjustable in any way. Once it is installed it isn't going anywhere =)
