0.78ar t4 turbine housing...

[renxun]

A 1jz wid 264 cams, if given a t04R 2.5"turbine wheel,coupled wid 0.78ar t4 turbine housing how far would it takes roughly to spool up to..err.. lets say 1.5bar? would wanna "agak" where would the powerband range be...

im building 1 for d coming drag. i hv 0.58,0.68,0.84 but dont have 0.78.... and im wondering if anyone willing to sell me a used unit so that i can experiment it.?

0.78 and 0.84 not much difference i guess... if i were u, i will use .84 since u have it already..
6cyl 1jc should be ok using it for drag race.. even my 4cyl using 1.01 now... the trend now is big turbo for big hp.. just my 2 cents... good luck..

i think 3000 spool up and 4700 full boost,the turbo big or small depend your use in drag race or daily drive,1jz fuel cut at 7000rpm wiz stock ecu?if your engine rpm can set more highly is better...
