EF not performing to potential.
Okay so I ran my car a few weeks ago, and out of bout 12 runs, my best was 15.2.... In the 1/4
So anyone out there have some times of their ef or other with a Ls swap?
Mine is a b18a, and has 402 crower cams, I/H/E, blox intake mani, billet 68mm TB, accel wires, NGK iridium plugs, and a ysk1 trans.
And just so everyone knows, I'm not bragging about that 15.2 time, frankly it seems very low for what I have done to it..
I use 94octain every fill up. it does NOT have adj cam gears. header is half smashed on the bottom on one of the two tubes. (from bottoming out)
The compression probably isn't the best, cause when I had the head off I could wiggle the tops of the piston a little bit lol not sloppy though.
Not sure where to go from here, there are no codes one the ecu. The TPS and MAP sensors are good. So I'm left scratching my head... Just curious if anyone has kind of the same set up as I do and what kind of time your running?!

Re: EF not performing to potential.
1.) What do you expect, you are not even tuned.
2.) You obviously have a tired engine - the weakest B18 at that. They need major head work to benefit using those cams as well as a compression bump.
3.) Running higher octane than you need absolutely doesn't benefit you in the slightest. You should read up on octane and it's requirements.
4.) (Sort of goes with 1-3.) If you were tuned you could potentially get more power and/or utilize your setup better with the fuel you run.
5.) You should always have adjustable cam gears to time the engine perfectly - on our engines it makes a bigger difference if the LSA is off than on that nasty SBC, SBF, ect... Aftermarket cams are almost always ground off centerline. Also, it makes an even bigger difference if you have either the head or block milled.
6.) Maybe you can't drive for crap? Post your time slip...
