My cousin recently bought a 88 CRX HF and the previous owner said the engine has been replaced.

I thought that the JDM D15B had vtec. Well, this one is a D15B (no numbers after B) with a 16 valve head.

what kind of 1.5 is this?

 

usdm d15b hf motor
He replaced the engine with a stock engine
88-91HF
88-91CRX-HF D15B6 1493cc
4 cyl, 8 valve
SOHC
9.1:1 c.r.
PGM -FI (DPFI 88-89)
PGM-FI (MPFI 90+)
88-89
62 bhp @ 4500
70 bhp @ 4500
Redline: 6800 rpm
83 lb-ft @ 3000

 

the d15b is not a usdm engine. the d15b6 is.

 

This one has a 16 Valve Non VTEC head, but with a JDM D15B Block. Is this a hybrid or something out of factory?

BTW. it pulls pretty good for some reason

 

it may have a higher comp. ratio. some of the d15s had a higher comp. ratio than the d16s...but anyways. its probably a factory engine, there is so many diff engines, it might not even be a JDM engne, maybe from the UK or somewhere. i used to have a good link. but my comp got reformatted again and i forgot to save them. i will look.

towards the bottem is gives you an idea of just how many different engines honda has made.

this is probably the information you are searching for.

When the DOHC ZC was the top engine, the D15B came in both single and double carb'ed SOHC versions, the dual-carb version delivering as high as 105ps in the CRX 15X. When VTEC became available, two versions of VTEC D15Bs were developed for the EG-series (1991-1995) Civic. One is the well-knowned VTEC-E which delivered an incredible 20+km/l mileage. The other is the VTEC D15B, a power implementation. The VTEC D15B is a very significant engine variant because Honda used VTEC to make it possible to generate as much power as a DOHC design from its SOHC configuration. Thus the VTEC-D15B generates 130ps and redlines at 7200rpm, ably replacing the DOHC ZC design despite having 100cc less displacement and one cam-shaft less !"[QUOTE=kyle h.]it may have a higher comp. ratio. some of the d15s had a higher comp. ratio than the d16s...but anyways. its probably a factory engine, there is so many diff engines, it might not even be a JDM engne, maybe from the UK or somewhere. i used to have a good link. but my comp got reformatted again and i forgot to save them. i will look[QUOTE=kyle h.]it may have a higher comp. ratio. some of the d15s had a higher comp. ratio than the d16s...but anyways. its probably a factory engine, there is so many diff engines, it might not even be a JDM engne, maybe from the UK or somewhere. i used to have a good link. but my comp got reformatted again and i forgot to save them. i will look.</TD></TR></TABLE>
