I'm about ready to do a head/can swap on my 02 ws6 a4 and I need advice on what would be good things to swap out while I'm already in there???

Car has:
bolt ons(lts,catback,intake, etc)
3.73s w/ TA rear end cover
Yank ss3600 stall convertor
Strange single adjustables on all 4 corners with 300lbs springs up front
SFC's,panhard,lca,lca relo brackets
Nt05R 315/35/17

Parts that will be going in:
Tsp prc stage 2.5 5.3 heads
Tsp torquer v2 cam
675 dual springs
7.400 pushrods
Ported ls6 oil pump
Ls2 timing chain
Ls7 lifters
Lifter trays
Tsp bolt/gasket kit

What other parts do you guys suggest I should change up or upgrade to while I'm already going to be doing the swap??? Any suggestions/help will be greatly appreciated!! Thanks!

How many miles are on it? Sounds pretty complete to me...maybe run a colder plug though. I'm running that exact setup but with a M6 and 4.10's, and love it! I think you will be happy for such a budget combo

The car currently has 31k original miles, what plugs would you recommend, I'm glad to hear that you like it...I'm really looking forward to see what the car makes after a dyno tune....what did your car make after the heads and cam??

Might need to up grade the fuel pump and injectors as well...it will be close. Just thought of that. At the moment i'm running NGK TR6's although i'll be going to BR7's when the nitrous is done. I bought the car as is, but it made 405 on one dyno and 460 on another....this why I don't trust dynos lol It runs strong for what it is though, and will hang with and/or beat others with higher dyno numbers

Cool, I was aware of the pump and injectors and maybe a maf sometime soon...but I'm hopping to see atleast 420rwhp...I talked to a guy at tsp and they said I can make 420rwhp easily with that combo and a good tune

HCI2000SS

iTrader: (2)

Yep, TSP told me 415-430 rwhp with this combo. The stock MAF will be totally fine

Yea they told me that I could make a little over 430rwhp with their 233/239 cam but I decided on the TV2 instead

Just finish my install with the same parts, just make sure you measure the pushrod lenght, I end it up going with 7.35 pushrods. Also I went with the trunion rockers upgrade

Id add a trunion upgrade and bigger injectors to the list

42 IB/hr injectors your car has low miles its unessary to change the lifter trays, unless there ruined or you bought them already.. Make sure you check the pushrod length. If money's not an issue get a under drive pulley. Oem header gaskets and locking header bolts from tsp won't be a bad idea. A longer under drive pulley bolt will make the install a lot smoother, I just used a 2x4 and pounded it on as much as possible so the old bolt will thread in. Also with the oem power steering pulley it's a huge pain in the *** to remove and install almost impossible to get to the bolts behind the pulley without a shaved open end wrench. I went ahead and bought a billet power steering pulley so a socket and extension would fit for easy install made life easier http://item.mobileweb.ebay.com/viewi...d=310671376804
I ordered tsp 7.400 pushrods and ended up going with 7.350 after I checked, lots of shop rags, I used a razor with a push handle to remove the old gasket off the block. Before careful and inspect all your vacuum hoses for cracks or leaks I had to replace couple of my hoses. Craftsman makes swivel sockets if you dont alreay have I used my tremendously during my heads and cam swap(metric) helped out a lot.

Oh yeah oil pressure sending unit behind the intake mani. There prone to breaking really easy I broke 3 of them doing intake cam swap there really brittle. They sell for around 40-60$ plus you have to buy the deep socket for it

LS2 Lifter trays are a good idea. They are much heavier design than the LS1's and you don't run the risk of spinning a lifter.

Why such a high spring on a .595 lift cam?

Injectors are a must, fuel pump maybe but probably not. I didn't need one with 460rwhp.

Thanks for all the suggestions fellas, really appreciate all the help...brntws6 I'm getting the 675 spring because tsp is sold out on the 650 spring so they have me a free upgrade to the 675 at no extra charge, and will the #42 injectors be good? And will they help performance(for example if I don't get the #42 injectors and dyno my car then throw on the injectors will I see an hp gain with them?

You may max out your stock injectors forcing your tuner to pull timing. I am at 80% duty cycle with 42lb injectors on my setup.

Maybe someone else can chime in on that high spring on a lower lift cam. Not sure if it's a good idea or not. I would think it would cause the valves to work harder than they need to.

HCI2000SS

You will not see a gain from bigger injectors alone, unless your stockers were being maxed out to begin with. Plus you would need to have the car re-tuned as well

IMO it is a bit too much spring for that cam. It will put strain on your stockish lifters. Take a look at the Brian Tooley Platinum springs.

Yea I'm actually doing some research and I can't really find some solid answers some say the .625 spring is enough and some say the .650 is the best option but that's not an option right now because texas speed & performance is sold out of the .650 spring and I'm geting a head/cam package from TSP and the springs come included in the package....so now I don't even know what spring to get??? Tsp didn't mention anything about it..they just told me that they were gonna upgrade me to the .675 spring because they are sold out of the .650 but did not mention a single thing about being to much spring or the down sides of it?????

It's not the lift. It's the seat and open pressures. The .675" springs are overkill and will put needless stress on your setup. It's a recipe for premature lifter failure, valvestem wear, and possible camshaft damage.

Damn just when everything was finally coming together, ok so what your guys opinions on the beehive .625 sigale springs??? That's an option as well!

I'm sure that spring will be good since the tv2 has a max lift of 598 or so. Like Predsaid take a look at the Brian tooley springs.
