Calling all Boost brothers....what's next?

[LightningGa]

I don't post here much but browse all the time.
But it's almost that time again....time to tear into the car for the 2010 season.

Just looking for opinions on what I should do next.....here's what I have done already:

- Eaton M62 Magnacharger Supercharger Kit
- Custom 3” Aluminum Cold Air Intake
- Caspers Adjustable Fuel Pressure Regulator
- 28LB delphi trailblazer Injectors
- S&S Ceramic Coated Headers w/ High Flow Cat
- SLP 2.5” Mandrel Bent Cat-Back Exhaust Piping w/ Magnaflow Muffler and Tips
- LS1 MAF Sensor
- PLX Wide Band O2 SM-AFR + DM-5 52mm Gauge Combo
- Greddy Oil Catch Can
- Hayden Transmission Fluid Cooler
- Deleted EGR System

I plan on having the upper and lower manifolds port and polished as I should have already done this years ago when I sent everything out to be powder coated.

So in your opinion what should I add next and WHY???

This is on a 2000 Grand Am w/ 3400.

swap the m62 for a m90...

[Mars]

Upgrade Valve springs
R42LTS plugs, gapped small
Tunning
I would get meth injection for sure with that blower

that's all, tune it up.

Injectors might be a tad small...

I would go back to the stock 00+ fuel pres regulator and tune with software instead of fuel pres.

^^ , 3500 top end swap. And/or a cam.

Route the charge pipes to an IC, then back to the TB.

R42LTS plugs, gapped small

something i've come across before: for every atmosphere you add, cut the gap in half. good idea?

ex: 9psi and a .060 gap being .037 and 25psi being .021

Or keep the stock gap and go with high energy ignition coils and wires to maintain good light off at higher rpm. Maybe shrink the gap a little but not too much. Not sure if polishing is a real benefit to a blown motor which has different flow character than naturally aspirated. Maybe a cam upgrade would be a better investment there instead. Bump the compression ratio up and add alcohol injection, that should improve your BSFC and give you more power and efficiency at the same time.

Forgot to mention I'm already using NGK TR6 spark plugs and I custom tune with PowrTuner software.

Swapping the m62 for the m90 is not an option on a Grand Am....it's only been done by a few by swapping out the 3400 for the 3800.

I think I'm going to upgrade the valvetrain like many have suggested already since I'll already be in there when I get do the P/P mani's.

Probably won't do the 3500 top end swap and I wanted to stay away from the alcohol injection for now....no room in the trunk for a tank.

Injectors are not maxing out yet so they're fine and everyone i know that is running this S/C set up is using the afpr as it raises pressure with boost. At idle it's set at the stock pressure.

Engine bay is really tight so trying to add piping to an intercooler is almost impossible.

Thanks for the suggestions so far......looks like I'll have about $800-1000 to spend including the cost of the P/P.

[IsaacHayes]

Ahh yeah that's right that's how that kit is routed. It's the RSM/ZSPEC centrifugal setup that can be re-done to use a front mount IC. (though no one has yet that I know of).

Looks like 3500 top end and or cam are the only things left really...

* P&P the blower (know the L67 guys get good gains from it)
* Springs/Retainers (reliability)
* Rockers or Cam (more power)
* LSD (better traction)
* 3500 Top Swap (should yeald more gains then P&P 3400 intakes)
* P&P Heads (more power)

Sell headers and S/C and go turbo? lol it will make more power if thats honestly what your looking for? hell you might make money after selling everything and still make more power.... Turbo's are much more efficent and don't strain the trans as much.

What else is done to the car? Suspension?

Looks Sweet BTW!

Relocate the battery and you'll have room for a small'ish air-to-water IC. You won't have room for a big one but it'll still be better than nothing. I've seen it done on an Alero.

Thanks for all the suggestions.
Keeping my current S/C setup.

Yeah....I know exactly what setup your talking about.....definitely a tight fit.

[RedZMonte]

It will be a tight fit but you could like he mentioned run a Air-To-Water intercooler. you can get them very comact. might take a few slight modifications but will be worth it... And you can up your boost as well. Ive seen a Alero as well local to me with a A-2-W cooler.

Alot of different shapes and sizes:

Being an owner of a highly modified L67(sorry ben). If I were you I'd really try and get an intercooler. If not then you should do heads & cam.

What kind of boost are you seeing? What size pulley is that? You have any knock with your current setup?

[LightningGa]

What springs would you guys suggest from Wot-Tech?

[BlackJack]

What springs would you guys suggest from Wot-Tech?

That would directly depend on what size cam you're running (or going to run later) and which heads. You really should discuss that with Ben.

There's a natural order of progression. You have to decide on what your total end result is going to be, then purchase your parts in a logical sequence. Otherwise, you'll be spending money on redundant parts all the time. Good luck !!
