head swap...

ok i have an 86 b2000 carbed motor and i more than likely will be picking up a newer b2200 tomorrow it has a blown head gasket and i was wondering if the head is no good and it is fuel injected would i be able to swap my 2.0 head over to it with out having any problems????

Yes the heads are the same the lifters are whats different. I would use the lifters out of the 2.0.

im so happy i made the swap. i wrote a techie on it as well if you need some pics and info on it.

cool that was the only thing i was worried about was if its fi that it wouldnt swap over but thats good so if i just swap the head over i see gains or at least smoother performance?

no the hydro lifters are definetely not an improvement of mazda. ask anybody in this forum and they will tell you the same thing. i made the swap to solid and couldnt be happier. the hydros were a very poor design and always leak down and wont hold pressure. you can buy brand new ones and in some cases are right back where you started in a matter of weeks. if you have access to the solids do the solids hands down.

Justin,

You are entitled to your opinion, just as anyone else is.

Anyone in the forum, includes me, and I don't agree that solids are better.

I don't know what your experience was with your system setup, but you cannot tell me that "hydros were a very poor design and always leak down," because neither part of that equation is true.

Poor maintenance causes problems with any vehicle.

Maybe that happened with your truck before you bought it.

You also cannot tell me that valve lash at 12 thousanths of an inch provides more valve lift than a hydralic lifter will at zero lash.

Or that a valvetrain will last longer due to less ramp collision.

You probably cannot even tell me why a low reving, low horsepower (80-85) vehicle like a B series truck, i.e. utility vehicle, needs self-imposed slavery maintenance to optimize performance that the factory spent lots of dollars to attempt to minimize. It probably cost them money on the service side as well, as those who only get their vehicles serviced at the dealers were no longer needing adjustments done.

Why don't you go back to kettering ignition. It gives a longer coil dwell.

How often do you have to get out the toolset and adjust your rockers?

Ever burn a valve because you let a clearance get too small and you will get a glimpse of why hydralic lifters are an upgrade.

well yes point you have made are very reasonable. i guess its all in what you plan for your vehicle. for me i dont mind taking the extra time every now and then to adjust my rockers. i like the fact i know im not gonna have to listen to it tick all the time or not get any lift when the lifters are collapsed. if your not mechanically inclined or dont have the time to maintain the solids then the hydros are your best bet. the reason i hate hydros is because i went and bought a few new ones and they collapsed within a few weeks of being installed. as for the dealers losing money. i see where you are coming from. but at the same time i believe the early miatas and our trucks were kind of the guinea pigs for the new design to see how they were going to work and used the failed design to improve later models.

haha well i wont have to worry about the swap because it fell through =o\ anyways how exactly do i adjust my lifters because i do hear a slight tick noise and i dont wanna grenade my engine i am too poor for that haha
