ok well lets make a part list for what well need for supercharging....im gonna go this route and then twincharge later....GTP i look for you to be helping out on this thread....post em Up and ill update the list

1. SS/SC Blower
2. Intercooler (laminova im guessing)
3. SS/SC Intake Mani.(including cores for IC)
4. Relocation of washer fluid tank
5. LSJ CAI or stock intake
6. Larger fuel injectors
7. Possible high perf. spark plugs
8. Wideband O2 sensor and gauge
9. Boost Gauge
10. LSJ A/C lines(due to intercooler)
11. Complete remap of PCM/ECM
12. Complete LSJ pulley setup along with belts
13. H/E (LSJ, cobra, lightning)
14. LSJ head and cams????( is this really neccessary???)
15. Hardwire of IC into possible ignition system for power
16.


thats what i got so far so help me out on this....lets make this as good as possible cuz im 90% sure im goin this way....

 

bigger injectors as well as hp tuners for tuning the supercharger

 

You need the following (at least):
-LSJ Intake Manifold (including the cores for the ic)
-Heat Exchanger (from the SS/SC, or Cobra, or Lightning, etc.)
-Plumbing/pump for the IC system
-Supercharger
-Parts to relocate washer fluid tank to opposite side
-LSJ CAI (or stock intake)
-Larger Fuel Injectors
-Spark plugs?
-Wide band O2 sensor and gauge
-Boost gauge

Other issues to resolve:
-Relocate the washer fluid tank to the opposite side of the engine bay to make room for the intake tubing
-Would the pulley line up with the LE5 belt system?
-Do you need any other pulleys to route the belt to the supercharger?
-How do you signal the pump to turn on for the IC system coolant?
-Does the LE5 throttle body fit? If not, is the wiring the same for the LSJ throttle body? If not, how can you use the LSJ throttle body with an LE5 PCM? If not possible, how do you fab an adapter for the LE5 throttle body to fit the supercharger? Will this affect the fitment of the intake tubing?
-Tuning needs to be done for the PCM, not the supercharger itself. This means figuring out how to handle boost with a PCM designed for atmospheric pressure (2-bar vs 1-bar maps). How do you control boost?

There's no need for the LSJ exhaust manifold or the SS/SC downpipe specifically. Although, a header would be a wise investment along with a high-flow cat (or just a long tube header) to allow higher exhaust flow.

 

I think you're on the money ppazz1101.

Why can't we see more of you on ecotecforum? lol

 

He would fit right in with you hardcore egine heads over there

 

Si senior.

He's already a member too.

 

Lol... I forgot about ecotecforum. I'll have to check it more often.

 

maybe we could put an lsj ecm in and use its sensors but then ud lose vvt unless its hidden in the pcm somewhere.

Or run a larger map sensor and divide ve tables by the scaling difference...prob best bet

Still thinking over here

NJHK...you've got alot more gearheads here than you think...after hours of comparison, this is what we came up with in Pittsburgh..

Now for those issues...
-Would the pulley line up with the LE5 belt system? Side by side they look to be the same. All LE5s will have to use the complete LSJ pulley and brakcet/belt system. (Dealer supplied if needed)
-Do you need any other pulleys to route the belt to the supercharger? (See above)

-How do you signal the pump to turn on for the IC system coolant? This is ECM driven on the LSJ. However, worse case scenario is a direct activation (hard wire?)on engine start up. If we use LSJ maps flahed into LE5 ECm we may lose VVT but is that a deal breaker?

-Does the LE5 throttle body fit? If not, is the wiring the same for the LSJ throttle body? If not, how can you use the LSJ throttle body with an LE5 PCM? If not possible, how do you fab an adapter for the LE5 throttle body to fit the supercharger? Will this affect the fitment of the intake tubing? The LSJ throttle body and MAP sensor should be used. The wiring for the LE5 can be spliced and matched to the LSJ TB if it already doesn't match. Both are 3 wire TBs.

-Tuning needs to be done for the PCM, not the supercharger itself. This means figuring out how to handle boost with a PCM designed for atmospheric pressure (2-bar vs 1-bar maps). How do you control boost?
LSJ maps and LSJ MAP sensor is the easiest way. Worse case scenario is a standard GM3 bar MAP sensor and then divide ve tables by the scaling difference (not that hard). I know Hahn is using the LE5 MAP sensor to around 9-10 psi but then changes for more boost. Perhaps he is using the LSJ or generic 3 BAR?

The hardest issue in all this is if we go with the LE5 PCM/ECm we could cut and paste LSJ boost/mapping and keep LE5VVT tables (although these are incapable of being modded at the time with HP tuners). This would then solve both issues of HE pump and VVT.

Another issue is the AC lines. These need to be converted to LSJ lines in the 2.4s because SC intake will interfere with the LE5 AC lines.

 

Wow... George I had no idea you looked into it that much.

 

That's cause you are too busy playin with Xmods...

 

If you decide to drop VVT, then using the 2.0 cams and pulleys and getting rid of the VVT actuator would be the way to go. Or, at least re-time the existing cams to the position they're in when VVT is engaged. Otherwise you're loosing a lot of performance if the cam never advances (which is what would happen if you just do away with the VVT actuation with no other changes).

If the VVT on the Ecotec is actuated by oil pressure, and you take out the actuator, you have to tap the hole that feeds the system presurized oil and screw a set screw into it to seal what would become a big internal oil leak otherwise (hard on oil pressure). If it's electrically actuated, never mind.

 

The most simple solution is to swap the LSJ head onto the 2.4 block...then you have a 2.4 LSJ can use all the supporting running gear.

 

ok so with all of this in mind, switching the lsj head, plus cams and what not, would it not just be easier to go with a turbo setup, if not cheaper?

 

For tuning i know Chris at Vector Motorsports has said they they've done atleast one supercharged 2.4 so maybe he could help with this.

 

does anyone know if he is a sponsor on this site...i dont think so....if someone can get me an email ill ask him...or one of you could....just run the idea by him and see what he could do for us.....i dont believe this is going to be a simple Hptuners tune...this is gonna be complex as ****.....so someone help us out on this.....as chris at vector if he can help or like i said get me an email and ill ask.....

 

Well I've watched LSJ swaps on ebay go for $1500 or so on the average with full tranny/sc/long block etc. Only missing thing is the heat exchanger core which you could probably get them to throw in with the swap. Now add that up against the cost of a complete turbo kit .........

 

If you swap the LSJ head/SC/PCM onto the 2.4 block you can use one of the many HP Tuner maps for the LSJ and tune from there. SIMPLE.

If you bolt on all the LSJ SC running gear/SC/Pulleys/IM etc and use a LSJ PCM you can do the same. You may even be able to take a cut an paste from the LSJ tables into the FE5 tables on HP Tuners to get a good baseline in the FE5 PCM for more thorough tuning.

This was not that EASY with subarus, Nissans and Hondas that I did a few years back. HP tuners opens up a whole new ballgame.

Dan (djt1185) or Rob (Fast06SS) is the guy[s] to contact. They can do just about any custom HP Tuners Program.

 

yea well i wonder what kinda of cheap parts they are puttin in that to sell it at that price.....by the way what is this swap your talking about...i have never seen it on ebay???

 

just buy a SS/SC and bore and stroke it to 2.4 ... a lot easier if your loosing VVT anyway

 

The swap is the entire motor trans and subframe from an SS/Sc car. Its usually taken directly ouot of a wrecked car so..I am not sure what you mean by putting parts in? Its the entire factory engine, pcm, tranny wiring harness and usually the whole front subframe with axles and mounts etc.

This is what you usually get for the "swap" including tranny. This one is WAY overpriced for the 2.4 I susually see around $700-$800.

does anyone want to lend me $700? http://cgi.ebay.com/ebaymotors/COBAL...43501196QQrdZ1

 

link doesn't work

 

A very Cheap Supercharger This link should work

 

I don't know if anyone said this yet, but

If you plan to use the SS/SC "intercooler" intake you will need:
A seperate HE (either stock SS/SC or aftermarket)
A seperate pump for the intercooler system
A seperate coolant reservoir

They don't plumb into the engines coolant, they use their own dedicated system for efficiency

HTH, feel free to PM me with any questions, I'm pretty sure I have P/N's for most of what you will need
