Are si's worth turboing?

tuning is your friend, if you want 300 reliable horsepower, I would change a few things to the engine
300hp your gonna want a new bottom end w/ some stronger rods and so forth, and some headwork, you have to figure thats close to 100% over stock, so yea your gonna need some other things, but not impossible, and it would be cheaper to do boost than n/a, and krazie said it best GOOD TUNE!! 
btw: i'll let ya know if its worth it or not here in the spring since i'll be boosting
btw: i'll let ya know if its worth it or not here in the spring since i'll be boostingAt 300hp your at your limit and it won't last very long. I was asking myself this same question a few weeks back and it will come down to what you reallly want in the end. The way I saw it for me atleast was that a turbo will be faster than all motor duh but the thing is I really like how all motor feels when vtec kicks in not that boost doesn't feel nice. I just figured I can get a longer life out of my engine if I stay all motor than if I go turbo so that's what it came down to for me but yes it is defenetly worth going turbo on an si you will be very happy guaranteed.
any b series motor can reliably be boosted to 300 whp on a bone stock longblock. its all in the tuning. a well built kit, a good condition motor, and a good tune are the keys. you do NOT need a built motor for 300 hp. to all who say he does, go do some reading at evans-tuning.com and other forums where people actually have experience with high boost honda's.
Personally. I like well done all-motor cars. haha. N/A is best. If you wanna turbo get a b18 or something. LS engine. I've heard they respond much better to boost than a b16. I've heard b16's arn't totally repsonsive to boost. lol. I dunno. I think the sweetest engine would be a really well built d series or a b18 non vtec. 
However boost is the cheaper way to go for alot of power!
However boost is the cheaper way to go for alot of power!turbos are great but there is a reason honda has never made a turbo engine. maybe becuase the sound of the all motor makes them jizz but i think that a B16 reving to 10K with some ITB's, stage 2-3 cams, springs whole deal.... is the hottest s**t. turbo is sick but why did you buy a honda if you want a turbo car. hahaha J/K.
http://forums.evans-tuning.com/ read up. there are MANY of his cars making well over 300whp that have been on the road for several months, even years. and hes one person. there are many, many more over on honda-tech, hondaswap, etc. just because theres no one on clubcivic making that doesnt mean they dont exist.racerx661 said:
That's a pretty good site and I serched thru it and found a few who had done it. But me personally wouldn't do it. It just seems like your pushing it too much to me, I mean your pushing double the whp you originally had. What I couldn't find but wanted to find was how many miles they had on their set ups.handlebarsfsr said:
again I like to see a reliable one....meaning daily driven (atleat 40 miles a day)...b16 STOCK bottom end cant take it....to obtain 300 whp you would have to be running around 16 lbs of boost, 3 bar map, etc...... the engine cant take that much pressure...it will blow...when we build cars we either use hondata (if we wanna be cheap), aem ems or motec...we our buddy shawn tunes our cars...handlebarsfsr said:
When it comes down to it I think we have a different definition of reliable-
yes 300hp in a stock b16 is possible, I never stated it wasnt, in question is the reliability

you really didnt click that link did you. people running 300+ are more like 8-10 psi, using the stock map.

and heres some food for thought too. http://forums.evans-tuning.com/viewtopic.php?t=2860
they are usually tuned with uberdata/crome/neptune, all free tuning programs. you seem to misunderstand the basic concept of boost- that the hp is only there when you need it. if you drive 40 miles a day on the highway, you may not see boost at all the entire drive, unless you ask for it. having a boosted car also means putting premium gas in it, and changing the oil often, and making sure to have proper cooling upgrades. a responsible owner, with a well tuned car, can have a 300whp b series last for years. heres a few threads i came up with.
