It has been said that 230'ish wheel hp is achievable with this turbo on ca18 engine on SAFE boost levels(12psi). max on it is 15 so you can see why i stated SAFE.
Suporting mods consist of;
full exhaust/bolt ons
intake
fmic
and adequate bov
boost controller/wastegate
also i wanted to get an idea of everyones set up here on this ca18 faq. so state what you are running and what problems you had for instalation, weather using ca parts or sr parts. ALSO, i'm asking if everyone who posts here can provide any dyno results with pics if possible.
thanks,

SR T25 = .64 A/R turbine housing .80 A/R compressor housing.
S14/15 T28 = .64 A/R turbine housing .60 A/R T04B compressor housing
I think 230whp is possible with the SR T25. I'll let you all know when I put my motor in. I'll be using the SR T25 as my "break-in" turbo. My power related mods will be--
CP forged pistons
fmic
3" exhaust
Z32 MAF
450cc injectors
