hey guys im looking to put a lt4 hot cam kit in my 94z28 a4 i already have cai and catback...do i need new lifters and what else should be done to help the cam work better and produce more power im looking to build a reliable z but still push more then stock..the car has 105k on it what else should be done to help overall performance..thanks guys

 

If you indeed have a 1998 z28 that will be an LS1
The hotcam was designed to fit the LTx series engines(93-97) and is not cross compatable with the LSx series engines.

 

Get a better cam

 

Ain't nothing wrong with going with the LT4 cam. There are a few people here that have used the LT4 and have gotten mid to low 12's using this cam with very minimal work. As for you're question, I'd use a new set of lifters and a new timing chain. All the bolt on's will help performance so keep that in mind, as for gaskets Idk if they still recomend the impala head gaskets but those would work and help bump compression for more usable power.

 

I'd recommend at least some headers. What rear gears does your car have?

 

if i do get the hotcam kit...should i get diffrent springs cus i see all u guys saying that u should if u have a lt1 and are getting the hotcamm kit....if so what springs would be a good match for that cam kit...thanks agian for the help

 

pretty much any spring rated for .550+ lift assembled on LT1 head

 

if you are purchasing the hotcam KIT as you said in one of your posts, you will get the springs with it... the kit comes with LT4 springs and GM 1.6's... and those springs will do just fine with that cam

 

I see he edited his post due to youyr response, which was the right thing to do. However they do make a hotcam kit for the LSX as well.

 

ya i di edit it haha that same day i was looking at my buddys 98 camaro and i ended up putting in 98 instead of 94 haha...thanks for the help guys

 

yes, but he stated he was looking to put an LT4 hotcam kit in his 98z28... lol

 

Yeah I see how that could be confusing now that I reread it lol, my post not the original response. There would be no confusion to that, two different motors and the correct response. I was trying to say that they make a hotcam for the lsx engines as well as the ltx engines, for some odd reason I took it as it said only hotcams for ltx...my bad and I apologise.
