If depends on how well the turbo charger set up is engineered. If it is well thought out, with mild boost (7PSI) you should be in the 220 HP range. With wild (15PSI) 300 HP. That is with a few tweaks and care.If the system is not well thought out. The engine will end up toast due to lean ignition, engine ping, or thrown rods.Before you get too far down the road, better ask yourself what you are going to do for a transmission. The stock unit may not be able to take it.

an LS motor is the motor to turbo charge for hondas, you wont be able to do a cold air though as the intercooler replaces the intake, with a good catback, the right exhaust manifold for the turbo (i like ramhorns but you lose ac and ps with those) the proper waste gate, proper tuning and fuel management you can crank out a good 200+ hp on stock internals, a cat back would be necessary because you want your exhaust to flow more smoothly, but kinda correcting what you said, a cold air intake will not turbo charge your motor. Keep in mind a turbo is not something that is cheap, it will require a new fuel system, hondata or something similar for tuning, dyno time, possibly a new head gasket depending on your engines condition, and if thats the case, replacing all the gaskets is not a bad idea, on top of replacing your head bolts with arp head studs, it wont hurt you either to upgrade your intake manifold, and get a bigger throttle body, your looking at anywhere from 220-250whp on a stock b18bCritic is refering to a Greddy turbo manifold (turbos replace the header) there are multiple designs depending on waht you hope to achieve, if you want to keep your power steering and AC you would go with a standard log style cast iron manifold, they look basically like a stock but they dont offer proper boost management (not all cylinders are hitting the waste gate) There is another style, not sure of the name i have no expierience with them, that basically looks like an aftermarket header, some of these still allow p/s and ac some wont, the biggest difference is that the waste gate will measure off of 2-3 cylinders oppose to just onemy preferred and the best for races apps is the ram horn, basically its a 4-1 header with a turbo flange, this usually, if not almost always eliminates ac and power steering, but it gives the benefits of an acurate boost reading (all 4 cylinders pass through the waste gate, regulates your boost alot better) something final that just occured to me, ebay turbo kits, are a good stepping stone ( 800 bucks for an intercooler, cast iron manifold, and a turbo) just keep in mind, that you will need a new bov, waste gate, and the turbos are usually hit or miss. I specify a cast iron manifold off the ebay kits just because the other stainless steel manifolds are weak metal, and will crack and break open under low boost

For sure DO NOT LISTEN to "old man dirt", obviously from his answer he knows little about forced induction and certainly is not aware of the formula for calculating incremental power gain from forced induction system. "ron z" has got it right with decent engine preparation, performance exhaust-catback, PLUS i would most highly recommend you install a greddy performance header...you can install mild boost turbo.This on stock - non forged internals should allow you to run 6-7lbs boost putting you just shy of 210hp....serious improvement.If you are on a budget once you have enhanced your engine as above , you can achieve the same blast/performance with a nitrous kit.it creates no greater stresses or heat on an engine than forced induction & is far cheaper.regards, engineer, fan of forced induction/owner of a supercharged car

Yea dude, definately. Boosting an LS is the way to go. Being that their non vtec, spooling up doesn't clash with the vtec kicking in. Also the transmission are PERFECT for forced induction. The gearing couldn't be any better. GSR and other Vtec motors generally have shorter gearing meant for acceleration, not top speed. Non vtec has longer gear ranges with more top speed, and boosting them help the turbo spool up for a longer time before needing to shift quick like in a vtec tranny. Good luck with it, you'll definately get some power. The blocks are good, but I'd work on the head, replace rings and seals and get it into shape before you boost and blow something, other than that your good to go. I'd boost at a safe 15/16 psi, no more than that without other upgrades like cams, fuel rail, throttle body, and other high end upgrades

Turbo that integra! Make sure you get an intercooler for your turbo. It doesn't really matter how much HP it has right now, it really depends on what type of turbo you get. Make sure you read upon the turbo you choose and mess with the PSI of it, so you can maximize the performance of your turbo. Don't go too overboard because the turbo will go beyond the efficient range.
