I am in the middle of stripping down the car so that I can replace a blown top end on my 95 Z24 w/ 2.3 and std trans. I have been searching around and can not seem to get the answers I am looking for. Since I have to replace everything for the most part, I want to get some more power in the process. I already know that I should be looking for the head with the #086 casting because it flows the best. I wanted to upgrade to HO or W41 cams but do any of those come with the hex drive for the power steering pump? Could the stock cams just be reground to the profile of the W41 and would I really see a 30+ hp raise without changing anything else besides the cams and EPROM? And lastly it looks like my car has a cam position sensor on the intake side, from what I read it should not if its a manual trans for my year correct?
Thanks

The 95s only used the cam position sensor on the automatics. None of the HO or W41 cams have the hex drive but you can buy the hex piece from GM and have it installed in one of those cams. The stock cams can be reground that much but you will need lash caps since the base circle is so ground down. Your 95 has ballance shafts like the 2.4s. Its a transitional year thing. That hinders your power making and the oiling system isnt up to the task of reving as high as HO cams rev. Also you would need a custom eprom as 95 is obd1.5.
In my opinion you would be better off to get a pre 95 2.3 from the scrap yard and freshen it up...snatch the power steering setup along with the engine. It will work in a cavy with some minor bending of the steering lines. And install your cams in that engine.
That would be a baaaaad idea to put on a 2.3. the compression ratio would be like 7.5-1
2.4 head on a 2.3.....BIG NO NO...
Your very option would be an engine swap. Remove your LN2 and swap in the LG0..... of coarse rebuilt and add W41 specs.

Im 99% sure I have a cam position sensor on mine. Im only working with a hayes manual so I could be wrong. If you are standing at the front of the car looking into the engine bay there is a sensor on mine all the way on the right hand side of the intake tower in the back side (middle near spark plug holes) just before the PS unit. Looks like a cam sensor. I was reading more on cams, found the exhaust cam from a 90-94 HO 2.3 motor on the shelf at autozone for $102. It has a slightly higher lifr, its also referenced in the sticky for the 'secret' cam. Would keeping the intake and swapping in the HO cam make much of a difference? I would spend that kind of cash for 5 hp gains!

Just swap in an LG0 for the best gains possible out of the Quads....then rebuild it to W41 specs including an LSD for your tranny, raise your compression a bit, then BAM you have a N/A beast

an HO cam definitely wont hurt. Many have mixed those cams and had good success. Be aware though they mix up HO and LO at placelike those, if it is a pre 95 LO cam it wont yield much gain since the only difference between that and your cam is .15 lift. That sensor you are describing is a different sensor in the tower, the cam sensor would be on the front right of the cam tower.
