Timm Posted October 23, 2008 Report Share Posted October 23, 2008 I picked up a LOT of supercharger stuff for EXTREMELY cheap. Listed as follows. Eaton GenV(5) m90 supercharger Alternator Lower Intake Manifold and L67 Harmonic balancer and the best part.... ALL FOR $80! but it gets even better.... ALL BRAND NEW! ---------------------------ENGINE-UPDATE------------------------------------ My 3800 sII is plagued with the dreaded coolant leak. We just replaced the upper intake gaskets (Under the plenum, and on the TB) We kept the same plenum and I'm 70% sure that's where the leak is. Because it's leaking again......badly. The coolant level in my in the overflow tank drops about 3/4 of an inch each day. I only drive maybe 20 miles per day (Non aggressively). And now my gas mileage is CRAZY LOW! I want this fixed before winter when it gets too cold to work on my car. ------------------------------IDEA-UPDATE-------------------------------- Maybe put my new supercharger on the car? Not have to buy a new upper plenum? -----------------------------QUESTIONS----------------------------------- 1) Will this require removal of the engine from the car? I think it might, just to get the harmonic balancer off. 2) Is the lower intake manifold the same in a 3800 sII and a 3800 s III? (both supercharged.) 3) How much re-wiring will have to be done? 4) Is a new PCM needed? 5) Will a L67 fuel rail fit on the Eaton m90 GenV? 6) Will my TB bolt into the SC with no problems? 7) Are there any cheap (but functional) bolt sets for the SC and LIM? 8) Will this even fit in my car? (Dimension wise) 9) How much (estimate) would it cost to get the aluminium plenum from a series III, and the throttle body adaptor? 10) Should I just get another plastic series II plenum?

Euro Posted October 23, 2008 Report Share Posted October 23, 2008 Well first off let me just say that you're a bastard for getting the Gen V and all of that other stuff for less than $100. Is the LIM that you got the Gen V LIM? If it's not, then you'll have to get it machined to fit the Gen V. 1. Taking the engine out is not needed. 2. the SIII supercharged LIM will fit on a SII 3. Ummmm not quite sure 4. Yes, or just send it to ZZP or someone to get it reflashed/tuned for your setup 5. Yes it should! 6. I'm prettttyyyy sure that it won't. 7. Not sure what you mean by functional bolt sets? 8. Sure will!!!! 9. You won't need a SII plenum, because the supercharger replaces the plenum. The SIII TB won't work with your car, because the TB is drive by wire, and not what we have. 10. See above. I may have missed a few things, and others will chime in. I WAS going to link you to a ClubGP thread dedicated to doing the Gen V swap. However it's not there anymore Quote Link to comment Share on other sites More sharing options...
88red4cyl Posted October 23, 2008 Report Share Posted October 23, 2008 I've always heard that the L36 is a little weak to throw a supercharger on stock, or at least that the L67 had stronger internals than the L36 did... Quote Link to comment Share on other sites More sharing options...
Euro Posted October 23, 2008 Report Share Posted October 23, 2008 L36's are usually quicker when you strap a blower to it. Higher compression ftw. Quote Link to comment Share on other sites More sharing options...
Timm Posted October 23, 2008 Author Report Share Posted October 23, 2008 7) I need the bolts to get the SC bolted to the LIM, and to bolt the LIM to the block and heads. 9/10) If I were to go the other route to get my coolant leak fixed, I'd need a new plenum. Just curious if I should get away from the supercharger idea, and just fix the plenum's coolant leak. Quote Link to comment Share on other sites More sharing options...

Just curious if I should get away from the supercharger idea, and just fix the plenum's coolant leak. IIRC that's like...$90 for the plenum fix, and another $40 or so for the LIM gaskets (might as well do those too while you have the plenum off). While you're at it, do the injector o-rings, thermostat gasket and seal, and so forth. Let me know if you're interested, as I just recently did this whole thing on a 96 Regal identical to yours.

GP1138 Posted October 23, 2008 Report Share Posted October 23, 2008 I do believe Shaun bought an L36 from a junkyard and threw the S/C on it. Might ask him what he had to do. PM digitaloutsider. Quote Link to comment Share on other sites More sharing options...
Timm Posted October 23, 2008 Author Report Share Posted October 23, 2008 There are plenty of guides for getting a m90 genIII on a L36, but not so much the genV... Quote Link to comment Share on other sites More sharing options...

ismellrealbad Posted October 23, 2008 Report Share Posted October 23, 2008 My first response would be say fuck all that n grab an N/A plenum out of a yard and just fix the problem. but since you got that entire setup for 100 bucks.... I recommend trading your giant headache for a smaller one. sell all the series 3 stuff and go get yourself the series 2 replacements Quote Link to comment Share on other sites More sharing options...

(both supercharged.) no, however you will want a LIM that has been modified, because the fuels injectors enter at different locations between the l36/l67. 3) How much re-wiring will have to be done? not much. there is a harness adapter set available. 4) Is a new PCM needed? absolutely 5) Will a L67 fuel rail fit on the Eaton m90 GenV? no, see #2. need ZZP fuel logs. 6) Will my TB bolt into the SC with no problems? no, need an adapter 7) Are there any cheap (but functional) bolt sets for the SC and LIM? no idea 8) Will this even fit in my car? (Dimension wise) yes i dont know if ZZP or anyone else will tune a 96 pcm. i also dont know if they clearance GenV blowers for the conversion yet either. clearancing will be needed for the fuel logs that are needed. read this also. http://www.zzperformance.com/grand_prix/products1.php?id=382&catid=109 Quote Link to comment Share on other sites More sharing options...

I didnt read his original issue closely enough. after which, idk why it'd be the plenum in the first place, but he needs to make sure the leak/consumption isnt something worse before any generation of blower goes on there Quote Link to comment Share on other sites More sharing options...

I didnt read his original issue closely enough. after which, idk why it'd be the plenum in the first place, but he needs to make sure the leak/consumption isnt something worse before any generation of blower goes on there Well I figured the "dreaded coolant leak" is caused by the known issue with early model L36 regals where the EGR stovepipe runs too close to the coolant passages near the throttle body and causes the plastic to become brittle and crack, causing leaks. The new plenum in the Dorman kit on rockauto includes a revised stovepipe that completely solves the issue. I just did this job on my girlfriend's sister's car. It can be done in 8 hours if you've never done it or anything like it before and have a Hayne's/Chilton's manual. Quote Link to comment Share on other sites More sharing options...
Timm Posted October 24, 2008 Author Report Share Posted October 24, 2008 I've removed my intake plenum maybe 3months ago. Yes the gasket was melted. I replaced the gasket and nothing else. I should have also bought the plenum... I can't find any L36 plenum's on eBay... Anyone know where to get one for cheap (That is still good quality?) I think this link http://www.zzperformance.com/grand_prix/products1.php?id=382&catid=109 just killed my dream... :-( Quote Link to comment Share on other sites More sharing options...

I would definitely recommend it. The gaskets even come already on the intake, so you literally just pop it on and tighten the bolts (after you change the stovepipe and a few other accessories).

Timm Posted October 24, 2008 Author Report Share Posted October 24, 2008 Alright, I think I'll just go with the new plenum, for cost effectiveness (and ease, since this is my Daily D.). I've seen used GenV SC's on ebay for the lower $800's. But I'll be happy with enough to get my ABS fixed, New Tires (the ones xtremerevolution has), and a Plenum. Also would be great to have some extra cash to finish my carputer... Man, there's a lot of stuff I could use some extra cash for! I'm not expecting to get $800 for it, but any extra cash would help! Also, that's cool how they ran it all on the same belt. Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted October 24, 2008 Report Share Posted October 24, 2008 I think you made a great choice selling the stuff off. It's not really worth the effort that it would take to supercharge your car, considering it wouldn't be long before the transmission grenades itself, plus you're not taking into account the tuning of it all. Not many people will sell of an off-the-shelf PCM to accommodate what you're doing. You need to add an extra extension to your harness for the MAP as well. The L36 block is identical and strong enough to put up with boost. The difference in the L67/L36 are the connecting rods and pistons (obviously; that's where you're getting your compression from). The cam profile is much different. You would also definitely need L67 heads, LIM, valve covers and fuel rail. A good fuel pump would be in order as well (L67/L32 cars are equipped with a higher-flow fuel pump). You'd also need the harmonic balancer. I'm probably forgetting something else, but I'll post back if I remember. Quote Link to comment Share on other sites More sharing options...

Andrew Posted October 24, 2008 Report Share Posted October 24, 2008 just a FYI. ZZP sells used GenV blowers for $500, so i wouldnt expect any more than that. but for your investment, score!!! Quote Link to comment Share on other sites More sharing options...
