Hey guys. I'm new to the LSJ platform (as well as super chargers) and I have some (potentially stupid) questions about this. I read the entire LSJ thread on performance mods and I've read a few on the TVS supercharger. So here are my questions:

I want to upgrade my car for now with just enough modification to make decent power with the M62 blower. I was gonna go with ZZP 3" intake, Bosch 42lb injectors, ZZP 2.9" pulley, ZZP midlength header/down pipe combo with 1.75" primaries, Tsudo Performance 2.5" catback exhaust, ZZP Stealth HE, OTTP Rotating mounts, and a tune. Has anybody had a similar setup with real time Dyno numbers?

My other question is if I was to install all of the above, could I install a TVS blower and not have to change anything major? (Excluding injectors, tune, etc.) Also, would I have to have the head ported and polished, upgrade the springs, and/or upgrade blower components because of the TVS?

 

In order to change to tvs you would need 60# or 80# injectors and a new tune. Also an ls4 throttle body is recommended but not required.

 

Is that that would need to change is just the tune and the injectors? TB isn't a big deal. At least not to me. If I did this then yes I'd put it on just as a precaution. Would I need enhanced cooling components, like a meth kit or E85 or something? I read a bunch of threads that say you do and the a lot says you don't so i don't really know.

 

there is a plethora of threads on here about your same question I recommend u search more and read

 

No disrespect but I do search before I ask. Every thread I have read on this particular forum gives a roundabout summary of what to expect. Nothing too entirely definitive. I mean maybe I didn't search enough, in which case I apologize for not utilizing the search function to its full potential. But I was just kinda hoping to get a more definitive answer on these specifics.

 

If I was you and I knew my goals then I would plan for those and not just the now type thing...So buying 40's and having to upgrade is pointless ..grab some 60's and you be good even for a stg3 tune..

Plan for the future not the past

 

Thanks. Good point. I'll be looking into what I want as a finished product instead of a "temporary high" so to speak

 

Just in case you didn't get the best results, googling your search with "cobaltss.net" at the end may help; that's not to say you didn't. The search algorithms for the site itself is pretty screwy.

Good luck with getting the power you're looking for. if you want a super clean LSJ to replicate, check out Staged07SS. He used pretty damn specific parts, mostly from the GM build book. While it's not the highest hp, his powerband is awesome and it's an awesome setup. (No offense to anybody else lol)

 

there is no magical answer that each mod is guaranteed x results there are to many variables at play that is why you get a roundabout summary thats why the more you read and learn the better the results

 

You would need a heat exchanger, dual pass and option b at least. E85 is its own cooling mod but if thats not available to you, you can use 93. Meth is optional. Depends on how small of a pulley you plan on goin and how hard your goin to run your car. Just as everyone is saying, there is no magical answer. Every car is different. You need to plan ahead and not cut corners. Saving a couple hundred bucks now could end up costing you a couple grand in the future. ZZP has an article about upgrading an lsj that might help you. Just type in "big power lsj zzp" on google

 

Belvedere, I definitely understand the no definitive answer thing. Every car is different and the variables are a huge dependency, especially on a used car. Thanks for the info though man. I appreciate it.

Double clutch, thanks. I'll have to look into E85 because I don't where I could find it around where I live. But 93 will work?

And I have another quick question. I was talking about racing a Mazdaspeed3 on another thread in the Drag Racing section and one of the guys told me to check my SC for a single bolt or 4-5 small bolts on the pulley. I have 4 small blue bolts. There was also a service tag on the front mount portion of the SC itself that said GM H2 I believe. Is this a GMPP S2 SC? And if so should I look for anything else to be sure?

 

4 blue bolts means u have gms2. There is no stage 2 supercharger. The m62 was the only one that equipped the lsj. The only other one out there that i know of is that eaton tested was the h62 but those were never available on a stock lsj and are a rare find

 

About your ported head question, I'd suggest talking to lsjion on here or josh billheimer on Facebook(same person)

I personally think it's one of the best mods you can do besides option b. The ecotec heads are pretty chocked and porting out the exhaust allows these motors to breath better, will make any mod you do that much more potent. Also helps with keeping intake temps down.

Also I'd take the griffin heat exchanger from Ottp over the stealth, griffin has a better core design far as I know

 

I have been talking to him via PM and he may have a H62 actually. He described some things to me and his SC is tagged H62 on it.

I told him to make a thread with pictures, but he may have scored a car that someone strapped one of the 3 h62's too.

Also, his car does have the GM stage 2 kit on it.

 

Oooooooh staged needs to get in here

 

Oh its actually tagged h62? In his post he just said h2. Ive never looked at the tags on my m62 so i figured that was normal for it to say h2

 

Thanks Haven, I will definitely look into the Griffin and yeah a ported head was definitely a must on my to do list lol I read up a bunch more on it and it definitely needs ported.
It was dark when I looked and I was using my hotels lighting to see it but I'm almost 100% positive it said GMH2 on it but I didn't really look close cause I was assuming it was all stock. Doesn't drive like it though lol

Oh and a huge thanks to BlackSSstg2 for helping me out through PM. I'm hoping the assumption of the H62 proves to be true. Not only for the rarity factor, but also for the better performance and efficiency. As far as I've read both those aspects are better with the H62 versus the M62

 

Here are some pics of my SC and the tag under it. Hoping someone can establish by this if it's an M62 or H62

 

That tag is on your gasket, not the supercharger itself.

 

If you're eventually going to upgrade to tvs go with buying the mods for that rather than wasting your money on mods for a m62 set up. Watch this vid of this guys tvs set up. Pretty badass if you ask me.

 

And then there's a cobalt on E85 with an m62 and a 2.7 pulley beating a tvs ion

 

If youre at stage 2, you could go GM stage 3 like me and 07stagedss..it is packed a lot of neat features!

 

e85 is not a coolomg mod and cooling mods do nothing but help recovery

 

E85 burns cooler than gas so your engine will not run as hot. It will help with recovery but more importantly it condenses the air entering the engine. Would you rather have hot air entering your engine or cool?

 

E85 gives you cooler combustion temps and does not help the engine run cooler the engine temp is controlled through the thermostat as for cooling the air charge temp there is know way to measure if it even as time to cool the air charge all you can do is speculate and hope for the time given it does the BIGGEST HELP E85 gives is the octane rating and it really helps keep knock at bay
