Ridiculous project but is it possible

[monstercrawlers]

Hi. I have bought a mk1 lt35 van that my original plan was to fit a om606 in like my other car.. now it has already a very sweet d24t engine in it which after doing some research here looks an exciting engine.. so plans have possibly changed.. so I'm now thinking 12mm pump head. Bit of head work. Large air/air intercooler and probably hx35 turbo... question is how hard is it going to be to see 300whp.. I'm very excited about creating a flying brick and would love to use the d24t but if this power is out of reach I might go back to plan A.. I'm also fitting the volvo zf4hp22 autobox to get rid of the ridiculous gear ratios
