14b turbo on b18c1 ?
 

I am piecing together a turbo kit for my 95 integra with a b18c1 engine in it and i have the opportunity to get a free 14b turbo off a first generation eclipes in mint condition and i was wondering if that turbo would be able to hold 5-8 psi till readline, i know that the t25 wont hold it but since the 14b is a little bigger i thought it might hold boost till redline

This should answer your question.

How to read it

First you need to do a couple calculations.

To get the Pressure Ratio, you use this formula:

PR = (14.7 + pounds of boost) / 14.7

so, you want 5 for min and 8 for max

( 14.7 + 5 ) / 14.7 = 1.34
( 14.7 + 8 ) / 14.7 = 1.54

Now you calculate your NA airflow rate using:

AFR = (engine size in cc * .061) * RPM * .5 * Vol Eff / 1728

so plug your numbers in and get..

(1800 * .061) * 5000 * .5 * .80 / 1728 = 127.8 CFM NA

*Volumetric Efficiency changes depending on a few factors. 80% is just an average. You could take that to 85-88% with a GOOD intercooler.

Now, multiply the NA ratio * your PR to get the AFR under boost 127.8 * 1.54 = 195.71

so, look at the compressor map and see that PR 1.54 intersects 200 cfm in the highest efficiency area. This is good. So to answer your question, a 14b at 8 psi will be extremely well balanced for your engine.

Then it's just a matter of plugging in numbers and seeing where they end up on the map.

I have absolutly no clue how to read that, can someone explane what that means so i dont feel stupid

Re:14b turbo on b18c1 ?
 

means that turbo is too ------ small...

thanks all i wanted to know :)

Care to elaborate?

Re:14b turbo on b18c1 ?
 

you put the RPM at 5000...???????
A B18C1 goes up to 8000+ ::)

Re:14b turbo on b18c1 ?
 

sure...i have a 60/63 (bigger than a 14b) and its still too small for my B18A...i would hate to have that turbo on my car...

Did you miss this part?

I'm not going to do all the work..
