Should i super charge my b18A or turbo which one is better in the long run and can i run a supercharger on stock internals?
very few have successfully went with a S/C on a G2, Turbo can make tons more power for cheaper than what it would cost to do a S/C setup. Search on here and you can find the reasons why S/C’s dont work very well for us G2 owners
you have a lot of reading to do before you even consider starting a big project like that. But turbo is the answer for many reasons. Go pick up some books by Corky Bell. He has written books in detail for turbo and SC
NOTICE: First, figure out if you can fit a supercharger, then consider this post.
I may not be able to answer your question, but I hav by really knowledgeable supercharger system engineers and designers. Lots of thought has be some insight of how to make good power with a supercharger setup. This information didn’t just pop-up out of thin air either. So here it goes!
If you can get big boost on a sc setup, but cool it down just as good or better than a turbo setup with its intercooler, then you’ll win. The problem with going the small ass JRSC route is that the blower is tooooo small, and can’t move enough air. After talks with the engineers at BDS, a larger displacement supercharger such as a 4-71, 250, or better yet, a 177, will give you the CFM you need in order to keep up with the turbo dudes. Obviously, you will need to slow the blower down alot since its displacement is anywhere from nearly twice as big to nearly three times as big as the engines displacement.
I’m sure that some would ask something like “Why would you put such a large ass blower on there just to slow it down?” Well, there are several answers to this, which are:
- With the little ass JRSC, you have to spin the shit out of it to create boost, but with the larger case, you can easily or effortlessly make boost.
- Less parasitic loss due to better SC gearing.
- Greater airflow! :dance:
With a larger blower such as the 250 or the 4-71, horsepower numbers such as 400whp should be a starting point when using methanol. When under boost with methanol for toooo long, you may need to start worrying about engine temps getting toooo low. I don’t think too many turbo guys can say that with their intercoolers. Actually, I don’t think that any of them can.
Now to get it to mount onto a b-series engine, it’s not the easiest thing in the world, but there are companies that make it easy for you, so check out the pics:
This last image contains an M62 sc or some other smaller sc (I think), which I think is a little pussy ass, and we need something larger. The only reason that I posted this picture is to give you some sense of how the sc will bolt up to the manifold. You can easily adapt the larger superchargers to this plate since it is just a flat plate with a big hole in the middle of it. Then you will need to figure out a better way to make the pulley drive system fit since it may be a bit longer than the supercharger shown (not 100% sure how much longer).
Then, there are people who may ask why don’t you just go with a Vortech or ProCharger style supercharger? Well, there are again, several answers to this question which are:
- The huge price! And yes, centrifugal sc kits cost an arm and leg.
- Less power!
- Not as bad ass! :dance:
The thing about going the large sc route is that you will need to learn how to be somewhat self sufficient when it comes to creating a final product. You may end up making alot of the pieces on your own. This doesn’t mean that it will be expensive. It means that you may not find some of the needed parts on the market.
NOTICE: I don’t encourage one to use methanol on the street, but if you can conveniently do it, then I won’t hold it against you. Just remember that methanol has corrosive properties, so you may want to swap to a fuel cell instead. Then again, I highly recommend the use of methanol for race only uses. Then you could start looking into fuels like ethanol which are less prone to corrosion, and make if not the same, but more power than methanol.
Hint: SC + methanol = faster than you’ll ever want to go. :rockon:
I hope this helps! I don’t think that you expected this sort of a reply. You’re lucky!
Superchargers are awesome, i have had a bit of experience with them on hondas, first off they just dont fit well on our cars and its virtually impossible to fit without serious mod’ing, also sc on a vtec engine is awesome i would recomend sc on a dohc vtec motor anyday opposed to boosting a dohc vtec, but a sc on an ls wont make much power since its a lower hp motor to begin with, its going to cost alot for small gains.
As for the ls, its a non vtec dohc low compression motor, imo its only really good for boosting or converting to ls/vtec. with turbo you can def get higher gains than a sc on an ls. Personally I have a boosted ls very happy with it and based on these reasons I would recommend that, on the other hand if you had a civic with a dohc vtec and was thinking of sc’ing i would otherwise say go for it
i have been thnking about this where did you get those pics at? i want that manifold.
(supercharger on a DA) = (getting off of your ass and making it work)
Come on people, THINK. Spend a few less minutes a day banging your girlfriend and try to figure out how to make a sc work on our cars. The guys down at JRSC have reassured that they have no intentions of making a kit for our cars. Vortech is toooo damned expensive. I know there’s a way! Even if we could get a supercharger to fit, I wouldn’t want to put that little ass JRSC on there.
Little supercharger :gunright: :bang: :bang: :bang: :bang:

you do know that supercharging your motor is boosting it right?
As long as he can distinguish the difference between supercharging and turbocharging, he should be fine.
its a figure of speech, i was refering to turbo as boost just out of habbit, sorry if that was confusing i dont think it was though…
to make that clear…10psi of turbocharger is the same as 10psi of supercharger, boost is boost duh :shrug:
^ no it isnt. it depends on size and effiency of what is making it.
Supercharging a honda is not worth it. Too much work. If you wanna be a hardass more power too you, but it sucks when ur 12 psi on ur JRSC gets eaten alive by an LS with a 60 trim on 7 psi.
