Well, I have a similar dilemma actually. However, I do know I plan to use the motor for road racing and auto-X, and I hope to go get a rebuilt, bored, and sleeved B18c from www.importbuilders.com (someone from this site recommended them). The engine will go into a '89 CRX Si. I am planning to go turbo with an off the shelf turbokit. I hope to get anywhere from 300-340whp for my final setup.

Three factors that matter to me are pricing, reliability and performance. I already have some ideas of I want based on what research I've tried to do on these forums, but I could be misinformed, so pls help me out.

On one hand, it seems to me that it's just cheaper to go turbo if you really want to make lots of power and torque. I don't know however, if it costs as much to go all motor (vs forced induction) if I wanted the motor to make something in the early 300whp range. What do you guys think? Does it cost about the same, or is it just really expensive to get power figures up that high with a N/A B18c? I'm also guessing it would be difficult to make decent torque figures without going fi, but I could be wrong

About the performance part, making power aside, I'm also concerned with the engine weight itself. Here's where I'm worried about fi. WIth a forced induction motor, I'm guessing there will be a lot more wieght with the sleeves and the actuall turbokit alone. Maybe the whole setup will weigh some 100 lbs extra. Maybe more, maybe less, I'm not sure. What do you guys think? Would the extra 100 lbs upfront be a huge problem? I'm also guessing an all motor setup ought to be much lighter, so it at least has that advantage.

In termns of reliability, I've heard N/A is a lot more reliable that fi induction in general. Is this true? What setup can I expect to last longer? A low compression, low redline, but highly boosted fi B18c, a n/A, high compression, high redline B18c, or something in between? Which tuners out there offer reliable products and good customer service for fi and n/a tuning? I was thinking about going with Toda Racing for n/a, but for RevHard or ImportBuilders for fi,

Pls let me know what you think, thanks!
