What do you guys think of this??
Well, Im gonna be undergoing a project on my N/A. I think it will be fun to build and have a quick N/A, since no one seems to really modify them all that much. MY goal is to be running a mid-13 second 1/4 mile, and still be steet legal(emissions have to stay). Heres whats in the works so far, just wanted everyones opinion on whether or not you think this will do it for me. Here ya go:
Rebuilt engine with a large streetport
ACT cluth and lightened flywheel
Ported Intake manifold
UR Underdrive pulleys
Removed A/C, P/S
Header(maybe)
High-flow bonez cat
Presilencer
Corksport singe SS cat-back
Pinapple racing 6-port sleeves
Reprogrammed MD race ecu (or whatever they are now)
K&N cold air intake, fresh air headlight cover, cold air box
Slight weight reduction (Aluminum Hood)
I think thats about everything, do you guys think I can achive the times I want, assuming good driver. Wasnt mazdaspeed7's N/A in the low 14's on stock ports??, So I think this should be a little quicker

two: he ran straight exhaust. You are not. BIG difference.
three. You will not hit mid 13's without nitrous, unless you go straightpipe and maybe a brdgeport. Expect mid to high 14's if you can drive.
four: skip the MD ECU and get an S-AFC. SO MUCH better. I'd also skip the headlight air cover.
four: be prepared to ditch a LOT more weight than just your hood. try p/s, a/c, insulation, etc.
five: porting the engine may cause you to fail emissions.
six: there are a few more things you may want to add... CDI box, electric fan, etc.
Just my thoughts...

eh
So you want to make a mid 13's NA that is streetable and legal in every way including emissions? Riiiggghhhttt... a bridge port will kill your emissions, a straight pipe isn't all that legal (gotta ditch the cats, they restrict a lot)... good luck though, you should concentrate on ditching a LOT of weight, that will help the most.

Ya basically tear everything out you don't need. Is there no way to get around emissions or what? If not then you prolly can't have a header so I would just go with a larger straight pipe to the cat and then to the catback. Good choice for saving weight and helping the flow with the single. You could do the TB mod and e-fan. Definitely work on weight reduction though. I think I would be very pleased with mid 14s out of an NA though. Especially one that passes emissions.

Well about the maybe on the header, after reading countless threads on the topic, the general consensus on them is that theyre not really that great, just make it louder, and maye move the powerband a little. I will definatelt at least port the stock manifold a bit though, to take advantage of the porting to the engine. I forgot about the E-fan too, thanks. You guys seem a little defensive about my expectations. This is just my fun little project, its not my daily driver or anything, I just wanted to have some fun and try and make a kiss-*** N/A. I dont want a full -out loud as hell , all out race car, or Id get a bridgeport and straight pipe, and gut all emissions stuff. But thats not what I want to to. If I do this and its as fast as I want, cool, if not, oh well. More mods Just wanted to get your guys opinion, not saying that this is definate and will be "x" fast. Chill out a bit. Thanks.

The header is the key to getting the last 10% of power out of the exhaust system once everything else is taken care of.  If you deny this, you have no clue what fluid dynamics and exhaust tuning is all about.
The cat ends up being a restriction.  The key to making power is running an open an exhaust as possible.&bnsp Go read the Racing Beat catalog - they have the most experience with tuning NA's and exhaust systems.  A true dual gives you the best powerband and highest power gains - this means LOUD.  If you can't live with LOUD, you're not going to come close to cracking 13's short of NOS...
I'd welcome you to try it.  Hey, maybe you're break all the conventions.  I'd like to see how much money your throw at this project to to attain your goals.  Remember, talk is cheap...
