Ok so just to start ill give yal a little info! I have a 06 base lightly modded I'm getting very bored w/ the lack of peformance I have noticed after riding in a comp g....any ways I have a m90 from a l67 (series 2 I believe) my question to anybody who knows more than I do about these cars (witch isn't too much) from what I've read that's. A gen 3 supercharger and gen 5's come stock on series 3's would I run into any problems trying to topswap a gen 3 on a series 3 motor? I tried using the search function but nothing was found! It I don't need the gen 5 this swap will be happening very very very soon! Thank you for helping me

Your in the same nick i am, You gota swap internal engine parts and electronics other wise car wont run right.

Yeah, you can't put a gen 3 on a series 3 motor. And besides if you only have the gen 3 M90 you wouldn't be able to do the swap anyway since you'll still need the heads, fuel rails, tensioner, harmonic balancer, injectors, etc. If I'm not mistaken you can however swap a gen 5 onto a series 2, but not a gen 3 onto a series 3. Hope that helps out a little.

I stand corrected. haha. However, you'd still need all the other parts, you can't just throw the M90 on the N/A LIM and call it a day. The Gen V blower is more efficient so if you really want to top swap and don't mind spending a little extra cash go that route, but if you want to stay with your Gen III it appears as though you can and it will work, you'd just need to get all the parts together. The heads on all the series III engines also flow better than series II, so again if you want to shell out the extra money then go for it.

That much I know isn't true. The blocks are all the same between the N/A and S/C and thus heads and LIM's are interchangable.

You will need the Gen 5 s blower so your drive-by-wire throttle body will bolt up to it. Look up Morad Parts Company and they can get you everything you need for a real good deal. There is a number on his website so you can call with any questions he can answer just about everything concerning a topswap

See I knew there was a reason you couldn't do a gen III on an L26. Haha.

IMHO, by the time you get heads, lower, blower, and associated parts you are better off saving some more cash and going with a base turbo build. A lot less bullshit with pulling heads and you will work out most of the basic bolt on blower Wbodys. All of my friends with blowers wish they would have just saved the cash and went turbo in the first place.

Victor my only issue with going turbo is its my dd and want to stay as reliable as possible! I have no problem going the turbo route I just want to stay as reliable as possible. If that makes any sence

Ok Then can some one please sticky a list of what is needed for a top swap cause i asked his exact same question 3 months ago and was told to switch the PCM, internal engine components, add the supercharger, and change the exaust other wise it would run.

I have no idea what "internal engine stuff" would need to be changed unless whoever said that was thinking of the LIM and heads, which do indeed need to be taken off of an L67 or L32 engine. The PCM also does need to be changed or the car will run like absolute garbage since the N/A tuning tables are too agressive for boost. As for the exhaust, it doesn't techincally need to be touched to run since the GTP's and GT's all have the exact same exhaust anyhow, but now would be a good time to add headers so you don't get KR when the M90 is added. Now would be the perfect time to do headers becuase you have to take the exhaust manifolds off anyway to get the heads off.

After reading more about this last night it sort of reaffirmed what I thought in the first place that you can't put a gen III on a series III. At least not directly bolt it on. The hiccup seems to center around the differences in throttle bodies as milestone said. The drive by cable mechincal TB's were attached to the S/C or UIM by 3 bolts, but the drive by wire electronic TB's in the Series III were attached with 4 bolts, so a gen III blower would need to be modified I'd assume in order to allow the different bolt patterns. Also the fuel systems are different between the Series II and Series III, but I'm not sure how much of a problem that would cause if you did try to go with a Gen 5 swap on a Series III.

In short, if you have a Series III, just get a Gen 5 top swap and call it a day, or go with Dave's idea and put a snail on it and call it a day.
