ok wen i finally get the rest of the cash to build my motor i want nos and lots of so how much would it cost to run say 300-350hp (to put in not use) and what times could i expect from this on a 250rwkw 12 sec falc

You would be very game putting that much n2o into what sounds like a fairly mild/hot clevo or windsor.

plate or injected n2o?

what bottom end?

Eb on Nos has run low 13's with 100 h.p jets.. Auto & slicks..Kit cost $1500...I would recomend an upgrade of fuel pump either inline or upgrade existing, higher flow injectors.Colder plugs and run with some retard timing..Say 6* advance instead of 10* to be "safe"...

well it will be built to handle a minimum of 200hp nos if im gunna spend the money and built a motor itll get done the way i want it done thus 300hp nos, and itll be built to run it repeatdly

Yep can be done imo. But have to start with bottom end up especially top notch pistons etc and better rod / bolts ..The inlet seems to be a restriction on power too esp e.b/e.d in this case 220 they seem to hit the wall ??? Assume inlet ?? As it didn't make much more power with bigger jets...

Solid bottom end obviously is the go.

And if done properly, and the n2o (even 300HP) is setup safely, no reason why it wont last.

go for it!

The std bottom end is the same as the old 250 atleast the rod bolts are...Crank though ballanced better will fit previouse engines...

so how much would a direct port wet system set me back, and would it be safer,easier to run or tune if the motor is run by an aftermarket cpu like microtech or the likes

single port wet system from oznos about $700, plus extra jets, splitting block, pipes and connections (what ever they are worth...)

Known problem with single port wet system is that intake manifold was only designed for air, so vapour (petrol) may have a tendancy to puddle or condense on the bends of the intake runners, which means you could back fire through your manifold.

i read a few posts a while back that oznos isnt all that great ive never had it so i cant complain or compare, and can you get a nos system that sprays over the piston or not, thats what i thought direct port was
