So for around the same price I can either get a used complete lsj supercharger kit or get full bolt ons. Which would be better? The sc kit would be really restricted with the stock le5 parts would it not?

 

Supercharger.

Don't waste your time with bolt ons

 

+1

 

Welp looks like I need to give mongo a text/call

 

this / thread now make an new SC build thread

 

Don't know how relevant this is, I have an LSJ and run a 2.8 pulley. lately I have been driving with my AERORORCE Interceptor set on boost reading. I notice most of the boost is typically under 8 lbs.

I was thinking to myself this is why it is a popular upgrade to add the SC to the 2.4

I think as long as you don't go too wild on the boost your 2.4 will hold up very well and the upgrade will definitely be worthwhile.

 

you might make 170whp with full bolt ons. you'll make 225+whp with the supercharger kit alone. Not too hard to figure out where you should spend the money first.

when I install my supercharger, I'll do a CAI and mid length header at the same time, just so I dont have to keep having it tuned.

 

Sold lol going sc first but I'll probably get a cai with the build then do headers dp and exhaust later

 

I would rant about how boost pressure doesnt cause engines to explode, but im just gonna let this one go.

 

I really wish I skipped the whole bolt-ons deal, I would have saved so much $$$ if I just went straight to forced induction. The only thing it was remotely worth it for was autocross, but still kinda pointless.

 

He's actually very accurate.

Cylinder pressure is almost always what ends up killing LE5's because the sleeves fail first. Boost is the most directly correlated parameter to cylinder pressure. Yes spark advance will increase cyl pressures, as well as high IAT's, but nothing as much as air charge pressure.

 

Turbo swap

 

s/c it. my car took 10k miles on a 3.1 then 30k miles on a 2.8 before the clutch finally started slipping under boost. was running 14.0 @100 on the 3.1 and bad tires. car has 115k miles on the stock motor too

 

So glad I went SC. It will wake your car up ridiculously over stock NA engine.

 

What makes you think a LE5 running 8psi and making 225hp with a supercharger is somehow as dangerous and a LE5 running 8psi on a properly sized turbo making 275hp? Horsepower is directly correlated with cylinder pressure, not boost pressure.

 

I regret not boosting my base model when I had it, instead I went for full bolt-ons.

As you can see, I no longer own that car and bought a boosted one instead.

 

I agree, not really the point I was making though. Maybe I didn't spell it out that clearly.

I guess I am talking from a daily driver/ reliability point of view.

I know that a number of folks on the forum have pushed the stock internals to some pretty impressive numbers with supporting mods. (which is very cool BTW)

I also know from first hand experience on my LSJ that if you start pushing things and you don't know what's happening with Temps, timing etc. you start blowing things up. Which is i am currently quite happy sitting with about 250 HP /232 TQ

That first blown engine made me a bit HP shy I guess.

I was simply talking about bang for the buck on a conservative SC setup .

My choice would be SC before anything else.

 

Or you could just save and buy Mike's LSJ-T and call it a day.

 

Oh yeh I know exactly what you are saying, just a common myth that's been going around for years that PSI somehow directly correlates to motors exploding. We have this indepth conversation every other thread on the HT forced induction forum. lol

 

I'll tell you this, going from NA to SC is a big difference. I'm impressed.

 

Yeah I get it. I learn more every day


In all my reading I can't believe I've missed that discussion.

Guess I need to read more.....

 

i drove mine everyday. proper tune, keeping it cool, and flowing is what is keeping mine alive

 

Would I be able to run a meth kit on a supercharged 2.4 if so how beneficial would it be?

 

It'll raise the octane lower the intake air temperature and thus make more power. It's definitely beneficial but if I were you I'd stay away from it seeing as yours is a 2008. The more things you do the closer you are to the 250 whp mark and you're just asking for trouble there.

 

Very very true
