hey guys ive recently installed a b18c into my eg hatch but ive decided i want forced induction. I cannot decide which is better and more reliably friendly. Which wolud be better supercharging ( constant power ) or turbocharging. Also if i ran a either what would be the most boost that my stock engine could handle safely for everyday driving? Also it has to be around $2250 so take that into consideration. TIA.

turbo, on sc you're limited on how much boost you can run by the pulley and you can only go so high.

go turbo. easier to upgrade down the road. that is going to be tight on that budget, but you should be able to piece something decent together. i wouldn't go more than 10-12psi tuned well for stock internals.

I would go turbo, but if you like that wine go for the s/c

I would buy a supercharger if you want reliable power. Turbo makes more, but if you're trying to put together a turbo setup on a little over 2 grand, I wouldn't expect to get much out of it.

As far as boost goes, I wouldn't even bother boosting a high compression engine like yours. I think 6 or 7 psi is about as much as they can safely/reliably take on stock internals, probably more if you want to push your luck.

i wouldn't use a supercharger on a 4 cylinder and expect good results, its a knife with two edges. In order for a supercharger to be efficient the engine needs to make decent power already, b/c the engine has to turn the supercharger via a belt. But in order to be able to take a lot of boost (especially on a dohc vtec) you need to drop the compression, but if you drop the compression the engine, out of boost, will be slower, thus making the supercharger less efficient down low. But if you want the engine to not be slow out of boost and spin the supercharger quicker off the line the compression needs to stay up, but that makes higher boost levels a lot more dangerous, b/c you're cramming a lot of hot air into a higher compression engine.
I'd say turbo the biatch, you will be happier with the results. I know a few people that supercharged b-series engines and totally wished they went with a turbo b/c the results were crap.

a turbo kit+ dyno tuning is well possible for around 2grand

Zeeman......i couldnt stop laughing when you said..."I'd say turbo the biatch"..lol...i agree...turbo all the way....yeee

alrite well then i guess boost is the way to go... as far as the compression would u guys reccomend getting new pistons and rods?? if so which ones wil be good? also how much whp can i expect on stock internals for a b18c on boost? thanx a lot for all the help guys.

chris_si98

you can be up around 300whp on stock internals.. anything above that i would recommend to start building it.

yeah man, go with the turbo...

here is the best advice. build the shortblock. nuff people say stock internal will withstand this and that. i can tell you str8 up, i don't know of anybody (o.k. 1 person) who has lasted more than a few months boosted on stock internals. turbo is like crack. one hit and its over. and for those cars that make 300whp on stock internals have some very good equipment feeding that stock motor. the problem is when boosted, the motor makes so much more power and your on it probably 75% more. you know quick balst to the store....8grand psssssshhhhhhhhttttt. hmmmm...let me pass that rig....8grand pssssshhhhtttt. you feel me? its addicting. as a reslut, you've increase the amount of abuse that your motor usually see with an additional 100whp. lol, g/l man.

not going too far with that much money tho with a turbo + tuning. Double that amount for an alright setup

imported_GHT

so how much should i be expecting to pay for the parts, and the tunnig?

chris_si98

thats a very difficult question to answer..

but anywhere from $2000-4000

turbo.....

I know lots and I mean LOTS of people running stock internals without issues. It's been said a million times, it's all in the tune.
