Hey, I was just wondering that when I rebuild my engine that if I should give it a streetport or not. I was planning on taking it to Stage III on Fc3spro.com's site from mild to wild. It didn't say anything about getting a streetport in any of the first 3 stages so I was just wondering. I mean, if I do have to street port it, I would want to do it when the engine is getting a rebuild. Thanks Jordan

Do it. It's not going to hurt anything, in fact it should improve your mileage (and performance of course). Just make sure you do it correctly and get some templates and take your time.

is this car a turbo?

because if so...Im going to make you aware that the TII's motor on stock ports is capable of approaching and in some cases exceeding 500hp with turbo and fuel upgrades...so you tell me, street port or not?hehe

If the car is N/A - porting is *pretty much* the only way to really increase power...

edit:
streetporting gives you better fuel mileage? are you sure? (genuinely asking, because the logic and science behind it would point otherwise....)

DragonRx7

If you get more air in on the intake port it should increase the performance of the same amount of fuel. I've read it in a couple of places about the effectiveness of a streetport utilizing the fuel more efficiently and therefore increasing the mileage. Of course this is on a mild to large streetport. Half bridge, bridge, peri and j-port is going to suck up more gas in those situations.

True, but getting HP numbers that high will be easier with porting.

I say port the bitch so that later you don't regret not doing it.

My engine is streetported and after passing emmisions EASILY with it, I wish I had gone with a larger streetport, half bridge or more.

Ok thanks guys. Also I was wondering if I would get more HP with the same performance upgrades without a streeport compared to the same set up with a streeport? Would it be easier to achieve say 250 HP with a streetport compared to not having a streetport?

DragonRx7

With the same mods on an engine with a streetport and without a streetport, the one with the streetport will produce more power.

JFR

Cool, that makes sense. The only real thing that worries me is screwing up the port job or doing poor. But with a template I guess it would be fairly easy. So, say I give it steetport. Rebuild it all and get it running. Could I just leave it stock with a streetport or do I have to accomodate for the new port job with other upgrades as soon as I do it?

You'll most likely need some fuel upgrades...

And uh, you need to do some practice porting on dead manifolds beforehand. Screwing up good housings is mehhh :|

If you're worried about it, and don't have time to learn properly, send it off to have someone do it (Like Kahren...= ownage porting)

JFR

Like larger injectors, better fuel pump, etc? I dunno though, I'm still contemplating wheter it's really necessary to streetport it or not. Well I know it's not neccessary but you know, first rebuild, and I don't need tremendous power. Unless there is really a huge difference of power between a ported and unported motor with similar mods.

Port it.. Upgrade the fuel and air delivery too and you will see the difference..

Denholm

what, specifically, do you upgrade i nthe fuel system?
walbro pump and bigger injectors? or what?

Denholm

But yeah - on topic - I'd say port it.

If you can get a GOOD port job, do it. Do it wrong and you can actually hurt performance... Also, templates only help with the inital shape, then you have to go in and smooth it all out and make it flow well.

JFR

Well, actually if the template is just for shape, then smoothing it wouldn't be too hard. I'm can work pretty well with metal, but I guess how well the port comes out, will it show.

streetporting is only going to gain you anywhere from 5 - 25 horsepower depending on who does it. but it is worth it... if your planning on modding it farther... any little bit helps... nad for the extra $300 to port it... why the hell not

JFR

Yeah, I think I'm going to do it. Now that I think about it, its nothing to get all wracked up on... a little grinding, a little sanding. Not a big deal at all. Just got to be careful. I also read on it so I think I will be good. "Don't forget to bevell the edges so the side seals don't get ruined." Alright thank you everyone for responding, my questions have been answered.
