Hey all could some one tell me were to look or know if a 2004 series3 would work in a 2001 series 2 monte carlo and can you inter change non super charger intake/plunum and put on a super charged engine?

 

ok that post is confusing lol

if you want to install a supercharger on a NA engine look up "top swap" and that will tell you what you need and how to do it.

the series 3 wont work in a series 2 car because of different throttle body etc. the block, heads, LIM are the same though

 

The 3800 Series II non-supercharged is an L36. The 3800 Series III non-supercharged is an L26. The engines are near identical (the obvious difference is the aluminum upper intake on the L26). The 2005+ L26 models have forged connecting rods for improved durability, that's roughly the only other difference.

The engines are interchangeable, but you have a couple of options:
Opt 1 - Get ride of the aluminum UIM and replace it with the stock plastic upper intake and throttle body from the L36.
Opt 2 - Keep the aluminum UIM on the L26, get an adapter plate from sites like ZZPerformance | 3800 Performance Parts | Largest Aftermarket Supplier! (rough cost of the plate is $100) and use your stock L36 throttle body or upgrade to an L67 (Series II Supercharged) throttle body. You also have to make a decision about the PCV venting (use a breather, re-route the tube for it, there are a couple of choices).
The original L26 throttle is not compatible in an L36 equipped car (as it's drive-by-ware, and does not use the throttle linkage).
Also, you will re-use you original fuel rail and injectors.

There is a lengthy thread here, with pics from a member by the name of Frank. He has an awesome white Monte, blew the L36 motor and swapped in an L26, keeping the aluminum upper intake.

One additional item. The supercharged and non-supercharged engines have a lot of differences. They have different compression ratios, the supercharged engine has fuel injectors going into the heads, not the LIM (like the non-supercharged). If you are looking to make a non-SC engine into an SC, it can be done, but requires custom tuning (due to compression differences, I believe I've read that you would want to run less boost). If you want to make a SC into a non-SC, not sure it's even worth the effort.
If you search about "Top Swaps", you'll a wealth of info on the topic.

I hope this information helps.

 

Sorry to of confused you I was given a 3.8 supercharged motor but mine is non super charged and I want to keep mine I need a bottom end and I was wondering if I took my intake and plunum and put it on the super charged one and the series 3 I could get cheap if it would work in mine

 

To use your intake you would have to change head's because on the supercharged L67 engine the injectors go into the head.. On the non supercharged engines the injectors go into the intake..

 

I'm not the expert on what you are suggesting to do, but I would say you will run into some obnoxious problems and need some tuning done.

What I'm about to say is without doing the research on it, it's just a shot from the gut....
If anything, I think you would probably be better off taking the Series III supercharged engine, dropping it in. I think you will need a different fuel rail, throttle body and a PCM tune to go with it. The stock trans will hold up, but if you have a 4T65HD, that would be better. If you have the resources to build up a trans or buy one from Triple Edge Performance, you'd be even better off yet.

Just some thoughts.

 

Just get a tune for an l67 with a 3.29 4t65, thats the setup i have in my 97

 

Thanks for all the help Im more old school than new. Im glad I found this web site now I can talk to others that share my passion for monte carlos. Thanks all

 

take the bottom end / block from a Series 3 3800 and the top end from the S/C'd engine (heads, intake, s/c, throttle body, fuel injectors, etc).

combine them together with stock trans

tune PCM with a stock 2001 MC SS file.


thats what i did and it's pretty damn fun.



*obviously there are additional things that must be considered during the swap/install, its a very easy swap to do though


** do not use the s/c bottom end with the 3800 (non s/c) top end unless you are going to turbo it. you will not like the results.
