Another NA ZX question... c'mon... you know you love em'

[Guest CarGuyChuck]

I've used the search function, but since it's a bit primitive, it gives the same results as searching for quantum physics on the internet and getting "Smart girl sluts...CLICK HERE".. Anyway, I am planning on keeping my 79'ZX naturally aspirated, and the engine is finally about to give out. It's just the valve seats, they are leaking, so I need to finally bring the car up on blocks to get them replaced, and I was going to do a few more things while I was at it. Can I use the N42 head on my car, even though it's not one of the 80's models? Also, does any specific company make piston kits and such for a little more power? I plan on finding something to tweak the ecu, but I haven't been able to find anything so far. I am going to add a 60mm throttle body, and a new air intake and exhaust while the car is up. I would really like my Z to go 0-60 somewhere under 6 seconds. I have seen a few na cars get there, and if y'all could tell me how it was done I would be really appreciative. Well, like I said. I did use the search function, it just didn't really give me what I was looking for. Thanks again for all the help in the past.

don't know about the n42 head but if you shave the current head which will raise your compression, larger throttle body/AFM, bigger exhaust pipes, add exhaust headers while your at it. This should get you started in the direction your wanting. Don't know about pistons and such either!.

MSA sells pistons and a whole shit load more.

Yes the n42 head will swap onto your block. All you need is the exhaust manifold and just bolt up your intake mani. If this is wrong please correct me i got this from a site can't remember where.

Shaving your head is NOT a good way to increase compression. shaving the head requires shimming cam towers which raises teh cam position, which then calls for thicker lash pads - all this modification (depending on the amount you shave your head) will make it hard to get a good cam lobe wipe pattern, since your looking at pistons, go this route...pay a little for headwork then get some custom domed pistons to fit your head to increase compression. A lot more stable and a lot more reliable.
