ok so I'm figuring on the Skunk2 Pro series 1 or 2's

I'm leaning more towards the 1's because they seems the best for stock compression USDM motor.

Heres the questions that I can't really find a definate answer to.

Now If I go with the Pro series 1 and I do in fact upgrade the bottom end down the line(type S pistons and researching crank options especially the H23 crank and rods) this will raise the compression will the series 1 be obsolete at that point?

Would it be better to get the 2's I know they won't work as well with stock compression as the 1's but if/when I do up the compression finally they will really shine.

I probably won't get around to the bottom end work for quite while so I'm really leaning to the 1's and if anything I can always swap out(prefer not too) to the 2's if they will really produce that much more power.

which plan sounds better?

Go for the pro series 1's then upgrade to the 2's if really needed when compression is raised.

OR

Go pro series 2's run them on stock compression for a little over a year probably

OR

Go for the pro series 1's and keep them in even after compression bump because the gains with the 2's aren't going to be that much more and probably just in the higher end?

Supporting mods at time of install w/ stock compression will be

AEM CAI w/BPI in stock CAI location
SMSP header
Magna flow highflow cat
Greddy SP2 catback
S300 tuned
w other stuff (homemade grounding kit) but thats the major stuff

other engine mods I would get before working on bottom end:
NX wet kit(for sure)

maybe
IM and 70mm TB port matched

I'm thinking option 3 but would like others opinions

This is for mainly a street car, that sees the track like once a month.

As always thanks for your time and knowledge

 

bumping up

any help would be apperciated

 

If you're going to build it all up eventually then I would just get everything together and do it all at once. Don't just build the head, tune it, then build the block and tune it again, then swap intake manifolds, and retune, change the header and exhaust. and retune...

Just assemble everything and swap it in and tune it once and call it good. You might want aftermarket pistons if you're going to run the Pro2s

I'll probably stick with the pro1's seems the pro 2 are a little more gear for a car thats mostly track and some street.
