D15B7 HEAD ON D15B2 BLOCK

Does anyone know if D15B7 head w/cam will work on a D15B2 block. Are there
any special timing problems.

 

do you mind saying why? iirc, you're going from a single cam 16v head
to another single cam 16v head, right? what's the objective?

 

To get the car running again. The existing D15B7 burned a hole in a piston
and also spun a bearing. I have a good D15B2 block. The head on the D15B7
has been ported and polished.

 

ok, get with the facts big guy. this is a "2ner" application. would
there also be nitrous involved? if so, what you're seeing is entirely
to be expected and what you'll keep on seeing until you do what you
should have done in the first place - rebuild the bottom end. you need
forged pistons and you need to get everything balanced and blueprinted.

 

"Burned a hole in a piston": Severe detonation

"Spun a bearning": oil starvation

Conclusion: Abused engine; owner is meathead. Or a racer.

 

Its all true, but it still doesn't answer my question.

 

believe so, yes. but you'll toast that block too if you keep doing
whatever it was that blew the last one. to get a motor that lasts, at
least get the forged pistons. that'll mean re-honing the bores. and if
you're doing that, you may as well do the other stuff. not trying to
knock you dude, but there /is/ a reason people pay money to take care of
this stuff - it saves a whole bunch of messing about, and big picture,
money too. if you can't afford it now, use your spare d15, go easy on
the juice, and save up for the rebuild that proper rebuild. btw, most
aftermarket performance components are for the d16's & b18's, etc. get
one of those if you can. hardly anyone bothers with the d15.

 

This is a learning experience for my son. It is good for him to learn these
things the hard way.

 

suddenly, you're making a whole lot of sense!
