Where to buy a good and affordable turbo kit for a 5 liter V8 in a '83 Camaro? And about what kind of gains can I expect with what budget? Or are there maybe other, better ways to improve my cars performance and be able to seriously take on all of those European sports cars here in the Netherlands? I saw a lot of kits on e-bay for around 1000 USD, but somehow I doubt they are very reliable, what do you guys think? Thanks in advance.

Thanks, man, for the affordable superchargers.
What kind of gains am I looking at there?
Do you have personal experience with those?

How about turbochargers?

 

Dont know. I am a N20 guy. you get what you pay for. I would look for used stuff and maybe expect to rebuild.

 

Used stuff? Where could I find that? Like on craigslist or something? Sorry, I'm not an American ;P

 

No great short cuts to real power, not to any great degree.

 

The Wynjammer superchargers are significantly less expensive than the 5000+ USD kits I've been ending up with on Google though.

And hopefully much better quality than the 1000 USD kits that are abundant on E-bay, but I don't have difficulty in believing that.

What kind of gains am I looking at though, Topradman?

And better fuel economy with a supercharger as Wynjammer claims, is that even remotely true..?

Plus another question, would it make a big difference to tune a 5,7l instead? (to first swap the engine for one a tad bigger) I just want to make sure I can outrun those Mercedeses and BMW's definitely, and not miss out on any performance, yet I don't have an incredible budget or such either.

 

Not familiar with the Wynjammer but if fueled right ( injected ) and around 9-10lbs boost with Procharger, I was still getting 20mpg highway and 450+ rwhp but that was in the infancy of my project (P1SC). Also still had 700r4 trans, 3.23 rear gears and a taller rear tire. I have put some Procharger kits on that picked up about 2mpg highway when driven for mileage but that is definitely with your foot out of it however that part applies to any vehicle. As far as power, size does matter. Bigger should always give you more. I personally prefer the larger engine but there are definitely some guys on here with 305's that are kicking *** too. I would choose the 5.7 over the 5.0 any day my self. ( I'm sure there will be some rebuttal to that comment though ) I have not personally built a blow through carb set up for myself yet either so a lot of variables to consider. I would assume that through an aftermarket computer you could dial down for fuel economy more efficiently than with a carb. My current setup uses a FAST computer that holds more than one tune to pick between for economy or power but that kind of extra will work contrary to a budget approach. Again, I am not familiar with the Wynjammer set up but I think if the parasitic loss is similar to a Procharger or a Vortech, boost will be boost and if you can get yourself to the 8-9lb mark, you will be happy with the results. Anything much past that and get out your $$$$$. With a good set up, I would say you could realistically pickup about 20-25hp per lb of boost but again, a lot of variables with cylinder heads, air plumbing, headers, etc....

 

I wonder how much radial load alternator bearings can handle. I have read about cranks breaking due to belt tension force. The small pulley on the SC means minimal tooth contact.
Looks like a piece of alum spun on the lathe to hold two bearings. Drop in the bearings and new shaft, bolt on turbo compressor and comp wheel and go. Anyone do the pulley size calcs to see what peak RPM it spins at?

As for effiency (BSFC), reading this may help:

Thanks for the replies, you guys, it's still a tad complicated but thank you.
And the answer seems obvious, Junkcltr, thanks.

So as for Wynjammer having good supercharger kits (and Edelbrock, super awesome but also way too expensive), I'd really like to know where I could buy good suitable and of course affordable Turbochargers as well?

 

You could easily go with a ebay turbocharger and increase your horsepower. The issue is going to be the efficiency of the turbo itself. It will not give you the maximum power available, but you will benefit from it. The ebay intercoolers (cx racing, etc.) will work just fine. A wastegate from Turbosmart and a BOV from wyntonm or emusa (from the reading I have done) will work just fine as well. Then it is just the piping and either v-bands or couplers and the turbo/hot/cold will be done. You then need to make sure you have enough fuel and proper spark. I would venture to guess for $1500-$2000 USD (don't know exchange rates or duty fees) you could put together a turbo kit. Then once you get bored with that you can upgrade your turbo to something more efficient and make even more power. Then the vicious cycle of wanting more and spending more will start to perpetuate itself.

 

Thanks for your reply.
So the Ebay turbochargers should work just as well and could be worth a shot, good to know. But what's the next step? Is there a trusted brand or place or something I could get them from? I might want to skip the Ebay option in that cycle if the difference in price isn't too tremendous.

 

It is always a tradeoff between price vs skill.

A quick way to make HP is to get the ebay "GT45 single turbo" kit at $675. Throw an offer of 500-550. Cut the driver's side header a bit or just use your stock manifold and make a new cross over pipe.

Should be good for 600 BHP.

Then you need fuel upgrades. Injectors, pump, and ECM/reprogram. I would get 42#/hr or bigger, 255lp hipress walbro, and MS-II ECM.

Altogether around $1500. Run it, if the manifold cracks get it fixed.

 

Thanks, man, that's pretty clear. I'll see what I can do and hopefully the Camaro will be a match for all of those European sportscars here. Perhaps this thread can be of use to others as well and maybe I will update with progress once I get to it.

 

Couldn't have said it better myself.

 

Be carefull with the ebay crap!!! Not trying to advertise or other, but those manifolds are very fragile and do crack easily and frequently. Better get a welder along with the manifold or you will go broke repairing it; heard stories, seen pictures and seen it myself.

Ebay turbos are acceptable, just dont try to break any speed record or you will end up breaking another thing.

I have never used an ebay wastegate, but if you get one make sure it is of an acceptable quality. A stock valve on the wastegate can cost you your engine and turbo.

Ebay intercoolers are OK, I have used them and work just like the real McCoy. Just make sure to air blow inside before installation.

DO NOT USE EBAY(no brand copies) EFI FUEL REGULATORS!!!!!!!! I personally had an engine fire when my cheap *** brother decided to use one on his road race wide body Mazda RX7/VG30DET cause in his own words; "it's the same thing as the genuine ones". Long story short, the regulator leaked by itself and one of the cheap hoses it cam with(rated for EFI) blew up which caused the fire.

 

Really gotta watch everything that is super cheap. Not worth an engine, your car or your life. A lot of side show snake oil out there, do your homework for sure ( course I guess that's what you are doing with this thread )

 

Found some sbc turbo headers at CX Racing:
