Attn 300Z folks

[Guest Ponyfreak]

I am looking for some info on the achievable power of a 300Z with a stock turbo. How much CFM will the stock turbine flow? What are the specs of the turbo? post here or IM me at ponyfreak100 Thanks!

I think Brett, at IPS, could answer all your questions.

Brett (aka Renner) may still be on CR; if he sees this, I'm sure he'll provide you with all that data.

i think the best ive seen out of stockers was 360hp. they are juss t25's

Here is the only compressor map I can find for the smaller .45 trim t25

And here is one for the .60 for comparison

The DSM community sees around 220-250 whp on a 2.0 motor at the top of the turbo's efficiency range. The 300z community sees around 400whp at 17-19 psi with a pair of them on a 3.0 motor.

The dsm t25 is a different turbo than the t25 used on nissans.

correct they are the .60 trim

[Renner]

Actually the stock Z32 turbos are TB02/22, smaller then any T25. Here are the measurements.

 

Comp:

40mm minor

51mm major

62 trim

 

Ex:

39mm minor

47mm major

69 trim

 

I don’t remember the exact max flow rating, pretty sure it’s in the mid 300 cfm range though. 380+rwhp is pretty easy to get with minimal mods on a Z32. I think my numbers were 370rwhp and 400rwtq with only an intake, cat back, ecu reprogram and mbc back in the day. Quite a few have gotten low 400 rwhp with them, but they are pretty much done past that. We probably have half a dozen stockers sitting on a shelf down at the shop.

Can a stock block handle 400rwhp? or are you saying your at the turbo's limit at that point, not the engine's limit?

for some reason i thought they were smaller than my stock td04. guess i was right.

The stock turbos are at their limit at 380-400hp. Stock engines usually start running into reliablility problems above 550whp, at that point the stock cast pistons give way.
