I was thinking about doing a swap later on down the road. But I don't want to throw off the handling chracteristics of my Crx so I wanted to stay in the same displacment with the 1.5 liter sohc vtec engine from japan. It comes in the VTI EG4's. I have seen the engine at it's best in Memphis,TN in a buddies 89' HF and his car screams. I can get one cheaper than a ZC and the ZC only has like 2 more hp than the D15B5. So I think it's a trade off. Plus the fact that when I spank on other honda's in my D15 and I'll pop the hood they will **** there pants when they see that it's a D15. And the valve cover looks like the non-vtec D15's over here too. HEH HEH HEH! The Greddy TD04H turbo kit fits on it make me like it even more.
