Honestly, the N* isn't justified unless the blower inlet is ported. Likewise, it's all money. I'd love to have an intercooler and ported heads, etc. I elected to build it up all around, since the engine is outside the vehicle. But I'm pushing it right now with all the money I've spent, and I've still got $500 to throw at a PowerTuner and MPS when I get the cash next month or so (I just bought a laptop for my classes well... which kind of helps with tuning ). Do what you can with what you can afford. You can always add more later, but you can't get the cash back if you need it.

Hey dudes!!! I'm in the process of doing the top swap. And I just got the install kit, the ss MPS with ss 3.8 pulley and all the good gaskets from zzp. I'm going with the GTP heads so I dont need all the other stuff zzp sells. I'm also running GTP LIM, injectors/rails and 72mm TB with a P&P blower, front PEM and 3" "off-road" DP LOL sshhhhhh LOL. I'm going to try and run the 3.8 pulley with the stock L67 TB and with out the pem and DP till I get the rest of the parts. I'm running 94 octane and have a tuner. I should be ok running the 3.8 for now right?

Wait, so are you doing the SS, but doing the heads too. thats more of a top swap. shouldnt you run the L67 S/C pulley and not the SS.

Unless you are just going to do the top swap...and not do the harmonic balancer? i think i understand, but i dont think ive ever heard of anyone doing that way.

Good luck. And let me know if you have any questions about it.

If you have a tuner, then the only way to tell is to scan it. 3.8 might be a bit small. maybe you should go with a 4.0 or 4.2 if you are going to be on the stock DP and manifolds.

Is your u-bend out of there?

OK I have any of you look at the kit the W Body Store offers. Will this take care of all of your needs for a top swap

http://www.wbodystore.com/grandprix/w-body-store-supercharger-conversion-kit-p-157.html

that kit, if you add the install kit, will take care of everything you will need, but it is overpriced

that it is overprices....the choices for the unexperienced is a top swap which includes heads or the ss kit which just changes the upper intake manifold...... blacknredgt check the information listed in the zzp ss kit page be carefull yournot mixing the 2 up......also does ne one know if with the mods i have and just had my engine rebuilt if i purchased 1.7 rockers do i need to change springs or ne thing and is it pretty easy to install onto the puchrods?

are 1.7's ok with your cam?

im not sure thats wat chico sugjested its a very mild cam so im lookin for advice i have no idea

NOt good, I would email the place you are getting you Rockers from, and tell them the cam size you have jsut to make sure its all good.

yeah, too much lift=bad news

most guys running more extreme cams (XP) cant run anything higher than 1.6's without mod'd heads

His cam has a very mild lift thats why I suggested 1.7 rockers it would give him a lift about 507 which would require better springs ,ideally a cam change would be his best bet but the rockers would help if he retains his current cam,by the way gteisele you did ask for advice on a N/A setup not boosted so if you plan on gong FI I would suggest a different cam .Chico(Pops)

gteisele- i would probably say run some 105# springs and new retainers if you are going to do it.

That is something that is no fun in the car. You gotta keep the valves from falling.

Eh, I did the springs on the car. Not a big deal. Just buy the air adapter, you plug it into the spark plug hole in the head and run your air compressor, just a few psi will hold the valves up just fine while you change out the springs.

I dont know squwat about what lift to what cam yet so I cant be of any help there. But I did alot of research and I found that if you get the gtp heads you dont need the modified LIM or fuel rails. all you need is the custom standoff and pulley and the SS MPS with SS pulley so you dont need to pull the crank pulley and all that stuff. I also just got the install kit from zzp and asked for a 73mm L67 TB gasket instead of the L36 that comes with the kit. and I made sure I was geting the right tune with what I was running, and just emailing in my bin. So I am running half top swap and half ss m90 kit

Of course. if you do the L67 heads, then you need the L67 LIM and fuel rails. you are doing the top end swap.

But why are you doing the SS pulley? just so you dont have to remove the balancer?
