yes, it completely normal for 1.6L motors to make **** power.

it's also normal for dynapack dynos to read 10-15% lower than the dynojet you probably dynoed on.


hey remember that time i said it's probably boost drop? that was cool.

That is because his turbo is WAYYYYY out of it's efficiency islands even making 8 psi at 6800. If the OP turned the boost down to 5 psi peak, it would make what we consider a "normal" looking graph and peak around 150 WHP on a dynojet.

I think the designation for this turbo would be "T-to small". It looks like a TD03-9b or there about in size.

Are you suggesting that his turbo is so small it can barely support 150rwhp at 7psi? Even considering that 150rwhp on a dynapack on a 1.6L is a very common number on almost ever sized turbo thrown at it?

I am saying that I don't think he has a 2554. He doesn't seem to clear on the issue, and I think he has something smaller than the 2554.

Braineack, I really want pictures of his turbo, so we can see if it is really a 2554. I specified that it looks like a TD03 9b because that turbo would only support around 150 WHP on a 1.6. This would explain the boost drop, and the low power. I dynoed a 3000GT on stock 9b turbos (3.0 liter with twin 9b's) on a dynapack dyno and had the same boost drop with a MBC sourced on the intake manifold.

Oh I see what you're getting at. I wouldn't be surprised. I mean it took us 4+ pages to get basic info from OP, it will be another 20 before we actually have his turbo's specs.


By the time we get all the information about this car/build/setup, ND's will be stanced clubricer rust buckets and we will be waiting for the NZ unveiling.

Here's raw rota-dyno numbers from Shueinds last dyno with his SR20 T25 on his 1.8L




and and here's one of my dynos:

Holly ****!

Looking at the results, everyone was thinking it was a 1.6 even though you probably already said it was a 1.8

Now I am even more convinced he has a tiny turbo smaller than a 2554... or the blades are bent to ****.

Here's the only pic on my phone showing the turbo. I'll get a better one when I can be bothered to go to the garage.

The blades all look fine and there is no evidence of any damage to the blades or the housing. There's minimal radial play and no in or out play at all.

looks like a 2554 to me, so explain the similar power output as the one I compared it to.

Indeed, 5 psi begi basic, very little timing, no intercooler, no MAT sensor, stock exhaust, 100 degree weather.

Could be the angle, but the intake cam looks advanced in the pic in post 227. That would explain all of his issues.
