Ok so my buddy bought a crx with a b16a1 engine. Ive had so many problems with this kid ordering the wrong parts because he cant figure out what car the engine came out of.

It a DOHC motor. And i was told its Vtec
On side of block (B16A1 *****) and on side of tranny is a big number but it started with S - 1*******

SO im assuming its a B16A1 with an S1 tranny most likely out of some integra. Can anyone give me any info on this engine or tranny.
Car it most likely came out of?
Did this engine and tranny combo come together or is it a diff tranny then was originally on motor?

AND ALSO can we turbo this engine without modifying internals? Ive been told you can run up to 10psi boost without hurting it. BUT sounds kinda sketchy to me. Dont know jack about honda engines tho. So please help!

thanks guys

maybe that will help?

b16a1 from what i know comes from an civic EF9 or a integra DA6. it is a dohc vtec unless he swapped an none vtec head for whatever reason. the transmission that comes with it is Y1(lsd or non-lsd) and YS1.

yes, you can turbo the engine but with low boost to be on the safe side, 0.4-1 bar. any higher depends on your engine condition.

 

forgot to mention that the transmission did come originally with the engine.

 

I hate these turbo questions.
PSI means absolutely nothing unless you tell us what turbo you plan to use.
A large turbo will be able to provide enough boost to reach your hp goal at a lower PSI level than a smaller turbo which will need to provide more PSI to reach the same hp.

Your hp goal is what matters here... not PSI.
The internals of the engine start to fail because they are asked to go above and beyond the hp that they can reliably provide.
They don't fail because there is some added compression from the turbo.
