Turns out I have to replace my lifters after I got it to the shop to do rockers. So having to pay a lot of money thought I would add some power when replacing parts. It looks like I have a couple bad lifters so a new set of LS7 lifters from Texas speed is looking like a great deal for 139 a set. The 98 WS6 is stock other than the trunion bearing upgrade for the rockers I just did. Future mods could include procharger but nothing likely till next year unless I am lucky.
Texas speed is recommending there 224R cam with push rods and beehive springs (said can use the stock retainers) for about $600 and then the LS7 lifters.
Whether I can afford to buy the better timing chain and oil pump right now I am not sure, but would like. Texas said they were optional especially on a low mile motor but they sounds like a good thing to do as long as the motor is apart if I can swing them, plus good oil flow will help durability for any motor.
To have had something go wrong at 40K is not encouraging. Motor not really running very poorly. Just found some (5) bearings during an oil change and assumed they were from the rockers. When I took all the old rockers out though all bearings were accounted for. I had heard a tick for about two seconds twice when on a steep incline and a slight misfire on occasion. Very subtle. But if the lifters have been damaged I am assuming either it is damaged or is just a good time to pay for an upgrade as long as the labor is not much more. At least get a more powerful motor when I am done paying.
The motor has 40K miles on it.
I realize I will have to have this tuned somewhere which will add to the cost.
It is in a shop a State away from me and time is limited...this was not planned. So I am wanting to do as much as I can as long as the labor is going to be the same to tear it apart.
Budget minded suggestions appreciated.
This is an A4 car BTW so Texas speed said with stock converter to stick to the 114 LSA rather than 112 on that cam...though I believe the GM hot cam has 112.
I had seen a write up in car craft 2009 where they used the GM hot cam and got 49Hp with a cam and spring kit for 415 bucks. There was a dip in power at certain RPM's but I don't think they had it tuned yet.
I see all sorts of other things possible including deletion kits. Money is just limited and I only have so much time they will allow me to keep my car at the shop or I would have planned this differently.
