Next summer, I want to buy an SSEi with and L67 and 4T65e trans. I am going to all different sites to plan out what kind of mods I will be getting. I'm planning on initially throwing in about 1000 USD in mods starting out.

My question is, I want some nice bolt ons, while having the ability to upgrade in the future, without sacrificing any parts.

So...

If I put on a set of 1.9:1 rockers, 3.4" pulley, CAI as a starter, and in the future I want to put on a cam. Is there a cam on the market that will allow 1.9 rockers, or will I have to upgrade to a different ratio. I know I'll be fine with everything else, but I know that some cams require larger heads such, so will I need to use differnet rockers and maybe port out the heads?

If you plan on doing a cam in the future like you say you are, then don't do rockers. There are currently no cams that are intended to be used with 1.9 rockers. I am sure you could use 1.9 rockers with some cams with the appropriate head work, but it wouldn't be beneficial. I would recommend a CAI, ZZP Modular Pulley System w/3.4" Pulley, AC-Delco 41-932 Spark Plugs, MSD Wires, 160 or 180 degree thermostat, shift kit, and then save the remaining money for a cam swap later. You will need to spend ~$1000 US for a cam swap, so save all the money you cam. Then do a cam, and get headers, and a custom PCM and you should have a nice setup. Then you can do ported heads or an intercooler and mods like that as you please. That is what I would do in your situation.

I didn't realize a cam swap will cost so much.

So basically, if I do a cam, I will be reworking the whole valvetrain and heads?

yes, better to go with the headers to start and pulley, the rockers wont match the cam and there is a lot involved in going that route. You can go inter cooler before the cam and well worth it my opionion, combined with a smaller pulley 2.7"?

nitrous?

No, I'm not interested in nitrous.

I'll probably do this:

180 Thermo
Trans Cooler
CAI
3.4" Pulley w/ belt
Plugs and wires
1.9 Rockers
(Possibly upgrade the trans)
Headers
Ported heads
Larger throttle body

and if I wanna go faster:

Intercooler w/ smaller pulley
Stage 4 M90
LSD

I'm thinking I'll stay with the stock cam.

This look good anyone?

Your list is pretty close to mine,Im looking into headers and highflow cat ,sending out for the 3.4 modular system in a couple weeks.A larger tb then probably a dhp pcm.Dont think im going to touch the rockers. That list looks good too me

Cool thanks.

Will the rockers cause any problems. I know they can really let more air come in at high RPMs. Do you think its a good way to go?

I think the rockers are a good alternative to the cam upgrade, easier to do and doesnt throw any codes. You wont get the performance of a cam though but you will be able to run a bit more boost, say 3.2" with headers and cai?
The intercooler will allow you to run a much smaller pully
