As title says, i got a t25 with a .48 comp and .48 exh. I also have a t3 with .42comp and in the exhaust flange it says 36 with the number 2 above it! want to know what turbo is gonna be best for my d16z6? want to eventually push about 15psi will the t3 spool up fairly quick? Thanks for any help

 

t25 is too small. T3

 

thanks for the reply dude, any ideas on when the t3 will spool or what psi ican get it to run?

 

anyone else?

 

t25 if you plan on autox'ing, t3 if you plan on dragging. t3 will have better top end, but t25 will put a lil more power inthe lower rpms

 

do you think some where in between might be a good idea? like a t28? how much power do you think im likely to lose down low using a t3? any ideas when it will start spooling?? thanks for the help by the way

 

YOU WANT LOSE ANY POWER WITH THE T3 CAUSE IT'S NOT TO BIG AS LIKE MY T3/T4 IT DOESN'T SPOOL TILL 4500, YOUR T3 SHOULD SPOOL AT BOUT 3200 SOMEWHERE AROUND THERE, THOSE T28 ARE GOOD FOR ABOUT 250-300HP,BUT T3 MORE HP ON LESS BOOST

 

THE T28 IS ACTUALLY A T3 WITH T25 EXHAUST SIDE.BUT I HAVE A FRIEND WITH A D-SEREIES WITH A GREDDY KIT THE GREDDY 15G IS BIGGER THAN A T25 AND AT 15 PSI HE DIDN'T EVEN HIT 250HP

 

I had a nissan t25 on my z6 for while. spooled up only about 200 rpm faster than my 50trim t3 with a .63 a/r standard turbine side. I can make 11psi at about 3000rpm with the t3.

It is even better than the t25 for auto-x too. Taching out 2nd on an auto-x course is kinda hairy but it is WAY faster than the t25. nice brakes are key

 

t28 is the best of both worlds.

Bailhatch brings up a good point that his t25 spools up almost as slow as the .63. One thing to keep in mind is that you need to figure out the exhaust housing... too big of one and you'll spool too slow and too small of one and you'll poop out the turbo.

T28 are nice, but the biggest problem with them is... Try to find one for a good price!

 

thanks for the input guys really appreciate it, think i will hook up the t3 instead of my t25 just to see how it goes! got nothing to lose as i've got both sitting here! think its going to be very tight on the block tho, gonna have to get some rods and pistons first tho! anyone know somewhere cheap? thinking eagle rods and not sure on pistons yet? might try some vitara pistons.
