96 si, using a motor from a 2000 EL(same I guess :P)
problem is, below 3k RPM, the car feels like it has turbo lag, then around 3k, starts to pull well, and feels really good at the higher rpm range, :/ not sure why but I hardly ever spend time @ 5k+ RPM
to give an example, i could easily spin my tires on my 96 CX in the rain, where as on the SI i have to actually launch the car at around 4000rpm to spin the tires
any idea what could be causing it ? maybe VTEC engaged all the time, the cam gear wasnt alligned properly? all stock too

if the cam gear isn't aligned properly than your timing will be off, and all it takes is a tooth or 2 to make the car run like ***.
Pull the valve cover off and the timing belt cover and check that ASAP.

well how did you check the wires and plugs? Do you know what to check for? Was the electrode rounded or not? If you have a fuel pressure gauge you can do a broad check on your fuel filter, if not you'll just have to look at the filter and judge how long it's been in there.. if it looks old replace it. You can also check what andrew said, but usually if the belt jumped a tooth the car will idle very, very lumpy. If it's idling fine, my bet would be an old fuel filter

I changed the plugs when I bought the car, they were fairly warn out, the wires I had the mechanic check during the tune up and he said they didn't need replacing, fuel filter is next! thanks I'll update the thread when thats checked
btw where is the fuel filter located in a 96 SI :P?
edit: could it be the VTEC is engaged early or wired to run all the time? there is no CEL though

i would also check your base ignition timing with a timing light. It could be too far retarded or too far advanced.

how is the ignition timing adjusted on a stock setup?

And the fuel filter is located on the passenger side of the firewall (looks like a black oval kinda) Make sure to use a line wrench (if you have one) for the bottom 14 mm nut, it can get pretty rusty and you don't wanna strip it with an open end wrench. Also.. crack the banjo bolt on the top and the nut on the bottom first before removing any brackets or anything.

Sick of driving, oh so far, to hamilton to borrow tools eh...good.
You adjust the base timing by rotating the distributor until the timing marks on the crank pulley line up with the mark on the timing belt cover....its very easy to do....so easy even c-pos can do it.

It's also could be just your mindset as well bro. Your CX has a Y7 and your SI obviously a Y8. A Y7's intake manifold is geared for low-end/midrange. Around 4K my Y7 falls flat on its face but it pulls pretty good up to that point. So it could also be your perception of the car as well.
