ok my friend wants to get a b18c ... and put it in his del sol ..... now i thought that was a great idea but ... then now he is talken about gettin a drag gen turbo ... will this engine be able to handle this without some mods on it ... will it give him alot of trouble ... or should he get a diff engine .. i mean the compression is so high on the type R ... i didnt know if the b18c1 would be better to get and redo the internals ... for low compression then run the boost up on that drag gen .... or even maybe get just a non vtec and totally redo it all over ... ... oh also he plans on runnin a 75 shot of zex ... i need some replys fast please ...

FACT: high CR + high boost = MOST POWER
FACT: most Honda enthusiasts have no clue what they are doing when they turbocharge a car, and when you mix high compression with a dimwit, or a person without an endless bank account, they will blow the motor.

Deduction: I would recommend that your friend does NOT turbocharge the B18C5 motor. It will make the most power, and IT CAN BE just as reliable as any other, so long as it is tuned exceptionally well...but for the most part, it is not a good idea for someone who is not a pro tuner. I would recommend he go with a B16A or a B18C1. He will not have to lower the CR at all, just get ample fuel and spark, and have the car dyno tuned...and he will be fine.

Well... then y do i always hear about gettin lower compression for a turbo ??? and my question is would the engine be able to handle it without any trouble

The reason you always hear that a lower CR is better is because in a way, for most street cars, it is. A lower CR allows the tuner more room for mistakes made when tuning. The lower your CR is, the more room you have for imperfect tuning. But, on that same hand, you car will be slower with less compression and equal boost. Think about it, why is it so important for NA race motors to have high a CR? Because there is no forced induction, and a higher CR, done right, in conjunction with a few more factors, makes for a better, more powerful motor. Now, add forced induction to that high CR equation, and what do you have...?...and even faster motor. But, on that regard, you really have no room for mistakes, so it is not as easy to take care of, and it is harder to tune perfectly. So, the motor CAN handle boost, but it will take a lot more time, care, and money in order to make it run perfectly.
