I hear ya!

So 100 kpa is equal to 1 atmosphere roughly, at sea level. Going from the previous post about making power in lean burn, you can make the same power running 22:1 AFRs @ just over the atmospheric pressure, slightly less than 1 psi, as you can in running in vacuum @ 14.7:1 AFRs. And with these benefits -

Incredible!

I may have found a turbo - 240sx Oem Nissan S14 SR T28 ballbearing turbo

It is a turbo off of a Nissan 240sx, comes with the t28 ball bearing turbo, which is in excellent condition, oem manifold, oem turbo elbow, intake inlet, and steel braided oil and coolant lines. $250.

Maybe good, maybe no? Here are the specs. It could be either of these.

S14 Zenki (1993-96) Black-Top T28:
Compressor: T-28, 60 trim 60 mm 0.60 A/R BCI-1 compressor in T-04B housing
Turbine: T-25, 62 trim 53.8mm 0.64 A/R turbine housing.
Stock Boost: 7 psi
Safe Boost: > 13-15 psi After that The Turbo is past it's efficiency
Max Boost: 17 psi
HP Ratings: 250 - 260 RWHP
Type of Bearings: Journal Bering


S14 Kouki (1996-98) Black-Top T28:
Compressor: T-28, 60 trim 60 mm 0.60 A/R BCI-1 compressor in T-04B housing
Turbine: T-25, 62 trim 53.8mm 0.64 A/R turbine housing.
Stock Boost: 7 psi
Safe Boost: > 13-15 psi After that The Turbo is past it's efficiency
Max Boost: 17 psi
HP Ratings: 255 - 265 RWHP
Type of Bearings: Ball Bearing

From what I understand about turbos (which is very little), this is quite a small turbo. It is smaller than the FP Red you mentioned earlier in the thread. Does that mean it will make boost easier and I should go with one slightly bigger?
I think that would be a very good choice. Also keep in mind on my Talon my other small turbo or high pressure turbo is a
13g TD04-13G-5cm2
40mm IND comp/50mm EXD comp
41mm EXD turbine/47mm IND turbine

In lean burn you will have a time delay because it takes some time for the heat to stack up at the turbine.
