the sawtooth build thread Options

[sawtooth]

Wanted to start a build thread for my na suby conversion. The car is my newly acquired '73 2.0L fi. It is very clean, appearance group, 2nd owner, 88K. I currently use it as my daily driver.



I want to do a suby conversion because I believe the overall package will have the performance, drivability, and dependability I'm looking for.

EDIT: I've changed motor selection slightly and am also taking a bigger plunge by going with a suby trans, see Post #49.

I'm so much more excited reading your thread after buying one. I will be picking your brain soon. Did you do anything to your motor? How are you getting the 220hp? I thought the 2.5 was like 160 stock. I still have plenty of research to do there. Your cradle is looking good man. I will need to hit you guys up for some info on that bad boy. If I can get 200+ out of this motor I will be thrilled. (IMG:style_emoticons/default/drooley.gif)

Hey Jamie, I just got back from taking another drive this evening. Too much fun, exploring the power band a little at a time until I gain more confidence in the whole setup.

So the 2.5 is 165hp with the stock ecu. Here's what I have over and above that:
- EMS Stinger instead of stock ecu. Outfront uses this computer in most of their suby dune cars and they say they can get well over 200hp with the stinger.
- Equal length header which is proven to add 10-15hp wheel HP by guys at nasioc.
- Cheap but effective high flow intake which really helps open it up.
- I'll also be doing cams which can add another 15-20hp
- I also have an ACT 12.9lb chromoly flywheel and exedy clutch setup. While this doesn't add any hp, it certainly brings the power on much faster.

Matt Monson describes this setup in the Suby Fever thread here. See post #2 where he says 225 is very attainable with this motor, that is with the stock ecu just doing cams intake and exhaust. The stinger adds even more tunable potential. So when I do the cams I should be close to 250chp at that point may be too optimistic but we'll see.


More than happy to share anything I can with you, just let me know what you need.
