D15B7 HP Mods?

By Loaf31
- Tue Jul 22, 2014 11:23 pm #347294 I was looking into some mods for HP for my car. I heard that you can drop an A6 camshaft in and it'll just be plug and play and give a few extra horses?
Also an over-bored throttle body?
If anyone else has any other suggestions, they'd be much appreciated!

PS Not going turbo or doing an engine swap or mini-me cause I just had the head redone.

The A6 and B7 are almost the same engine. If you're going through the effort to swap the cam, you should go aftermarket. Your only other choices are intake, header, exhaust. I doubt you'll want to tear the head off again and do some high comp pistons.
With those limitations, you're doomed to be slow. You've essentially ruled everything out.
Would you consider nitrous? That is the only thing that makes sense under the conditions you're imposing.

Get a good header. I got a DC sports one. Also, reflash the ecu. Go to pherable.net.
Get a custom exhaust made. Maybe a 2.5" to open it up with your bolt one.
Diff tranny will help with gear rations to help with acceleration.

Maybe you can find yourself a rare jsrc.

I'll be doing the Beast7 in a couple months if things go well.

Transzex/MistaBone founded this setup in '99. Nasty_Canasta took it and tuned it. Jomama/Chueyi also has a Beast7 but he messed up his timing at first and had a bad clutch. I wish things went better for him since he's the only one with a quarter mile video; he still ran 16.1 @ 85. These guys are all running IHE as well, but I don't really have faith in those mods and you already have the most important of the three for a mild NA setup.

An Ex/Si transmission won't add power, but it will make the biggest impact in acceleration. Ex = 1-4 shorter(5th same as DX), Si = 1-5 shorter.
