Ok, im new to the whole honda thing so i need sme help. i recently bought a 88 CRX si with a D15b7 engine, from what I understand this is not a crx engine but out of the 90s civic dx, anyway my first plan was to turbo the engine but then i came across a Z6 mini me head for real cheap and i couldn't pass it up even though i wasn't really familiar with it (all i knew was that it would add vtec). So now i have a d15b7, a Z6 head and a turbo kit. would i be better off just turboing the d15b7 or should i put on the z6 head and turbo that?

 

well, the z6 head will bump up the compression. turbo engines like lower compression. but with good tuning, you can use it.

 

In short, yes you should do both. But you need to spend a substantial amount of time researching. Both parts have their own pros and cons.
