A little help please (hx35/40) hybrid

I know this has probably been beaten to a pulp, and ive tried searching but not finding the exact information i need. Im trying to build a pretty solid DD with a track tune for weekends. Im somewhat on a budget now compared to when i started the build. motor is a 6bolt 2.3 strocker, head hasnt been modified but i plan on porting and ffwd dks2 cams. i basically need some information for supporting mods for a 500hp goal if possible. the turbine housing is a bep bolt on that i scored on craigslist for 150 new in a box. will this work? or would i be better off with a just an hx35?

Actually you're better-off with a HX40. The turbine flow of the HX35 bolt-on housing paired to your stroker is going to hold you back from making any substantial horsepower (500+).

Im actually glad you answered justin (turbo guru). when you say hx40 is that with a bep bolt on housing as well? or there t3 housing? what would you recommend for the head and cams? and fuel? I would like pump gas for the street and race gas tune for track.

You can use the bolt-on housing, sure. This housing has trapped 139mph on a 8-blade HX40 with a 2.0. The T3 housing would obviously offer better turbine flow but require many more custom-built parts (o2 housing, etc).

Not sure on the head and cams, although Dave gained about 6mph switching to a ported 2G head, CB-spec intake manifold, and Kelford cams this year over his previous unported 1G head. This is on a 2.0 as well.

2.3l and an hx40 go great, Im still on the bolt on housing and a stock 1g intake manifold and have trapped 130+ on pump and meth at 33psi. Im sure thats over 500whp, and im no tuning guru either so there is more in the car im sure

thanks for the input red. what are you tunning with? and what size injectors? ive got an aem ems and fic 880's and i have a choice of either 1g mani or a cyclone. are you still running the stock cams? im also starting to think these injectors wont cut it.

I use dsmlink v3, I would be lost with an aem. I maxed out 850's at 25psi with an 90+ duty cycle, and now run 1150's see about 70% at 33psi. I run delta (hks grind) 272s. I dont know much about the cyclone mani but I know the 1g mani has to go. Just orderd a jmf race mani! My head is also ported with 1mm oversized valves, but its an old port job done by bjs for a 2.0. I dont know how well it matches the 2.3 motor
