This isn't for a honda, but it's an I4 and I don't know where else to look, so I hope you guys can help me. My bud is building a 2.3 Turbo motor to swap into his 91 N/A mustang right now. .30 over JE pistons, crower rods, stock crank, all balanced and blueprinted. esslinger aluminum head, NX wet kit, and a diesel powerstroke intercooler. He'd like to make atleast 400 RWHP on pump gas, and 650+ on race gas. Tranny is a 3-speed auto. Anyone have any ideas on what would be a good sized turbo for him? He was thinking that he might need to go for something big like a T66 to make the horsepower at the strip, but not spool so good on the street.

And does anyone know if you can rig up a nitrous kit to stop spraying once a certain amount of boost is reached? Could you rig up a hobbs switch like this?

 

you can definately use a hobbs switch to stop spraying...
but if you build your motor strong enough you dont have to quit spraying!

 

get a t61, its the most flexible ebst engineered turbo below the t70 family there is. The compressor map is to die for. <in my best barbara streisand voice>
