I own a 94 LS integra. My suspension is all set, my brake system is all set, so all I need is my turbo now. I was planning on also buying some lower compression pistons/rods/rings too.

I'm considering buying a newer 240SX and swapping in the silvia motor.

My question is which one will be faster? Should I continue with my Integra, or should I do the Silvia car? I'm not too familiar with the Silvia motor, otherthan the fact that it puts out like 250whp stock.

Please help!

 

That really depends on what all you're planning on doing to them and how much you're going to spend. If I remember correctly, it's more like 250bhp rather than at the wheels for the Silvia. You'd be looking at quite a bit of money to swap the engine (direct from Japan, engine was never sold here). If you put the same money in the Integra, you'd probably have more power. Although, you do have the advantage of rear wheel drive for dragging or fun (power-on oversteer anyone?). So I guess it comes down to this...What's your budget?

Also, since the engine must come from overseas, you're looking at a much smaller number of people who are familliar with it as well as waiting on any parts that you need to get shipped over (if they're stock ones at least), hence more $$

 

IMO-the LS would look better than the 240, power output of both would probably be very close, but it really depends on $$ and tuning.

 

Don't forget, the Sylvia is a RWD chassis which has many traction advantages. The Integra, being lighter and less complex should be more reliable and get better fuel economy. There's also a lot of "science" available for Hondas and a zillion Honda shops should you get into trouble. The parts are also cheap and readily available.

 

You've already gone this far with your LS, you might as well continue. Trying to sell your car to a buyer who's willing to pay a premium for your modifications is very difficult.

That said, my opinion is that the ultimate potential for a lightweight RWD car like the 240SX is much higher than that for a FWD car. (Let the flames begin! )
