Engine Spec Questions
I guess this is my intro thread... hi
Anyways, my friend gave me this link to a calculator. It's technically a thermodynamic flow calculator used to calculate torque with certain input, but it can be used to help match a compressor to the engine using the specs of the engine and one's power goals.
Calculator Link
I'm wondering if anyone has the following numbers for a stock 94-95 1.8 engine:
-Air Fuel Ratio
-Specific Fuel Consumption
-RPM: I'm not sure if it's asking for where the horsepower or torque peaks or where the redline is...
-Volumetric Efficiency
-Max Injector Duty Cycle

What a waste of time....Just go off what everyone else has used and worked with...I'm using a nissan t28 turbo on my custom kit, most use t3's though.
edit: this is for an approx 200whp set-up.

Lol, thanks for the advice... my friend recommended I go there to find a good match, but if that's the general consensus I guess I can just skip it
Anyway, I'd like 200-220 whp... I'm trying to decide between a T25, T28, T3 or depending on my financial situation, a new GT2554R. I'd like to get one of the first 3 along with a BEGi mani/dp just to make things a little easier

Do a search on here you'll find tons of info on those turbo's and similar set-ups ppl have. I have the same goal, approx 200whp, my t28 will putout just over that before it becomes too inefficient (about 220whp). Good-luck

No, the T25 (well, the GT2554, at least) is good for about ~225-245rwhp; there are three people on the Miataforum right off the top of my head that're running in that range with that turbo.
The T28 (or GT2560) will be good for ~275-300rwhp tops. Quite a few folks have run those right up to the brink with their FM II kits.
If my goal were under 225rwhp, then go with the T25 all day long. Above that, T28.

Alright, after speaking to a friend of mine, I'm trying to decide between a 14B and a T3. I'd like to go with the 14B as it fits my power goals, but I'm also partial to the T3 in case the power bug bites again further down the road...
Since my friend isn't very familiar with miata's he wasn't sure about this question: are the flanges for the 14B and T25 the same? I was really interested in getting the BEGi mani/dp combo for the T25 so would it fit the 14B also, since the 14B and T25 are so similar?
