Default tips for my mod list?

i have the exhaust done to it already. i have my general ideas ofwhat im doing next. however, i would like a little guidence, i have read the guides and stuff like that on here. i just wanted to outline my upcoming mods, and see if there are any extra tips, brands to stay away from, stuff like that.

ls1 lid conversion
aluminum driveshaft
373s
cam
1.6 or 1.7 RRs (everything else that goes with cam upgrades)
shift kit
tune (i know for sure im doing it through pcmforless)

i will be redoing my exhaust after all this is done, i currently have a 2.25 exhaust with flowmaster muffler, so that will have to go after all this is done (will do LTs ory, and cat will be staying off). this will all be done over about a year or so. im mainly doing this cause i want to know about like what my results may end up being, if im missing anything, and things that may just be a waste of time.

(car is a '94 Z28 A4)

I'd redo the exhaust before RR's. But I'd definitely go with the 1.7's. And unless you're actually having the trans rebuilt, I wouldn't bother with a shift kit

Do full exhaust, then stall, gears, and some suspension then tune

well i was going to wait till i had all the parts in my hands, then when i have about 2 weeks of down time i was going to do everything, exhaust being the very first thing.

you do make a good point on the shift kit

what would be good for the suspension, cause it is starting to get squeeky, should i just redo it all?

Don't get an aluminum driveshaft. Just get your stock steel one balanced. save the money for something else.

How much does balancing cost? I picked up an aluminum one off ebay for $100...no more vibrating my whole car like a ************ past 75 MPH with my 4.10 gears. It's also significantly lighter and been proven to show 1.8 HP and 5 lbs of torque gains. Don't believe me? http://www.ws6.com/mod-1.htm

Every last bit counts....especially if your upgrading a known stock part that has issues. JMO

yeah i thought the alum driveshaft would be a fairly good investment. but if balancing offer around the same benefits may just go with that

Yea, but if you go that route you don't get the extra 5lbs of torque....the HP torque gains are because of the lower weight/inertia (physics here) of the ALUMINUM driveshaft....NOT balancing....all the balancing does is stop the vibrations. Why not get the extra torque AND fix the vibrating

Again, people miss my point COMPLETELY....why spend money on balancing when for that same money you could have UPGRADED to something better in the first place. The OP was the one who brought up alum driveshafts...If it were me I would do gears and alum driveshaft at the same time as mentioned because the vibrations do get worse with gears. Suspension and converter would be better mods for now anyway as others have said.

The problem is that you're not "upgrading". The stock alum drive shafts from the LS cars tend to break pretty easily when adding torque. So why not just get your stock steel shaft balanced and not worry about breaking anything.

Takes a lot more torque than a stock (or mild) LT1 is capable of to break one..replacing the old u-joints however is a good idea.

The stock ls1 driveshaft can only handle like 500hp??? or somewhere around that right, the lt1 is better for higher hp it can take it........

For suspension at least do lower control arms and torque arm at least

Do Lt
gears
torque converter
cam
intake
ewp
RR ( but I have question about RR, 1.7rr will they work with stock heads or do u need to do anything to support it? If some1 is doing a 383 and gets there heads ported and polished would gettin 1.7rr work and benefit well? ) sorry not tryin to hijack thread, just have always wondered....


And There should be a more updated mod list sticky b.c of all us newer lt owners
like in stages and different routes should to go with if you are wanting to do the different routes there are

i am going to be doing sub frame connectors, and suspension work, tires and all that, i did not include that on here because everyone knows that you need a good tire and suspension set up. i am going to be doing the tires really soon, im getting a set of z06 wheels, 17s all the way around, maybe 9.5-10's in the rear, im going to start looking at tires when i get them.

i do have a few questions about the torgue arm and sub frame connectors and all that.
im not looking for the cheapest brand, the way i see things is you get what you pay for. so my question is what would be the best brand to use, what would be the best set up for a DD, but also do good on the track.

(i made this thread knowing there are similar threads, and there are threads about proper cam to use and all that, but some seem to be from awhile ago, and alot of the local shops ive gone to, have said to just spray it, or boost it, which im not looking for)
