i have been peicing together a turbo kit slowly. at first i was going to get a holset hx35 and that deal fell through but... i have had a garret to4 hot side ar 1.15 cold .60 and a garret t3 a/r .48 and .30 so i am in the process of making a t3/t04 with a .48 hot and .60 cold. and i was wondering what could i expect out of this turbo. i measured the turbines on the hot and cold side the hot measured 2 and 2.5 in and the cold 2 1/8 and 2 3/4 in.so this leads me to my questions

1. is this good idea seeing that i have the parts that i got for around 50 bucks for both with no shaft play at all and both spin freely.
2. spool times any insight
3. peek hp this can flow
4. what psi will it push??
5. how can i find out the trim?( i tried it and got 64 but i might have it wrong)

this will be gooing on a f22b1 with a f23a head

and pictures

 

Damn, what about that china cabinet lol. I don't know if what you're doing
in that room is, well...damn.

 

just do it and find out. how are we supposed to know the specs to a hybrid turbo your making?

 

i am just looking for insight i am doing it and well see but at the same time it would be nice if someone can help me find out the trim.

 

trim has nothing to do with the housings it is the difference in the size of the exduce and inducer of the turbine wheel and the compressor wheel

instead of trying to explain this to you here is info from garrett with diagrahms and formulas, but it is up to you to find out the trim of it so time to bust out the caliper

trim is 63.73 and thanks for the link i found it last night. and started number crunching. so other than try it out what would you expect to see this turbo do on a f22? i am going to be putting it on later on in the summer and hope it does nicely my goals are 275ish whp do you think it will meet those goals

 

yeah with those trims it should be a pretty decent turbo for mid range power increase and still be able to stay out of boost around town

 

Negative, he is using a .48 turbine housing. that will almost spool at idle on an f22.

it should meet your goals, but its a shitty turbo for that engine. a .63 turbine housing would be better

 

isn't the big 16g a common turbo for the f22 it has a a/r of .48 and a smaller comp i think
