you can get some tunes that electronically lock to max lift, so it's possible kinda - the big thing is.. you COULD set the new ECU up for valvetronic... or you could not and just have it set to max power lol. the stock ECU *CAN* already control it, so the stock ECU can electronically max it out with the right setting.

It's not like anyone entering this sport does it because it's cheap.
Building an e30/36 race car seems to be the obvious answer now but it wasn't back then while still in production. It was only a matter of time folks start moving into e90 territory. And in 5 years when the F-series reaches its end, someone may do the same with that (even though an e46 would be so much cheaper to build). And I'm sure the majority of the reason behind choosing the n52 over the n54/55 is just based on club racing rules but its longevity and reliability are probably huge pluses as well.

would probably be cheaper just to do the 3-stage mani swap and tune... an N52 and ECU etc. can't be cheaper than a couple of grand
yeah an E36 can be made stupid fast for little money, tons of aero and suspension mods, turbo/sc kits/engine swaps
but it's not bad to make these cars quick, full M3 suspension, coilovers... and for 128's, tune and 3 stage, for all N52's... catless exhaust/headers and it's 300hp for plenty of straight line for not too much $ .. 300hp isn't slow by any stretch of the imagination.. and amazing handling.
