I am looking to possibly installing the Sport20 intake like the one available from CorkSport. Is the manifold close enough to the stock one on a '99 1.8L FD-ZE motor? I am wondering if I have to get a Sport20 fuel rail or any other parts to fit the system.

It should work, but why? You'll get more from the intake cam and it costs a lot less.

I am planning cam changes at the same time, but I know they'll fit I was just wondering what was involved in the intake change. As I understand the intake and both cams will net about 170 HP.

I sent an E-mail to CorkSport asking what was in the Sport20 intake kit and what would be involved in the change. They wrote back saying the kit includes everything to make the change including the manifold, gaskets, fuel rail and nuts/bolts.

I wasn't sure as I found a pic of an imported complete motor and noticed that the layout of many of the fuel system components were in different locations.

The stock FS-ZE Jspec engine you are referring to produces 170HP. The cams and intake manifold will not give you 170HP. The FS-ZE engine also has 10.5:1 compression pistons, and a different ECU with a higher RPM limit. I think the fuel pressure regulator is on the opposite side ours is on because the car the engine is from is right hand drive. The most cost effective mods available for the 3rd gen Protege engines (FP/FS) right now are the FS-ZE intake cam, headers, and N2O.

Don't put on the FS-ZE intake manifold you would just be wasting your money. Find another dual runner intake from a junkyard, port and polish it and you will see alot more gains than the FS-ZE manifold....ask any Prober and they will tell you the same.

Good point, but that's after doing the other mods.

Hi guys,

I'm not sure but I think the OEM exhaust is 2'' diameter.

Is it True?

Eric F

The stock exhaust on my '00 ES is 1 and 7/8th inches in outer diameter. The Bosal exhaust I installed is 54mm (~2 1/8th inches). It looks nice, but didn't make a noticable difference in performance. When I find a true bolt-on header for the car, these others things should hopefully make more of a difference. Right now, it appears the primary cat is the biggest restriction to airflow through the engine. Changing other typical bolt-on parts probably won't provide their full gains until the biggest bottle neck to airflow is removed. Once that's done we'll have to see how the stock ECU responds to the increased airflow.

Hey,

Ditching the primary cat...is that the first cat attached to the exhaust manifold? I'd assume so because it's first in the exhaust flow.

How does the system work...would you remove the first cat, and add a header and install a high flow cat in place of the one under the engine?(I think the Proteges have 2 cats).

Also, I'm guessing the stock intake on American/Canadian cars isn't that resrictive by what you guys are suggesting!?!!

I idealy would prefer turbocharging (it's just my style of building power) but there seem to be a lot of complications for designers getting a kit on the market.

All I want is 200 hp (without NOS)

Eric F

Yes, the primary cat is the one right below the exhaust manifold. Only some Proteges have the dual cat exhaust. With that, I would install headers in place of the stock manifold and primary cat, leaving the second cat in place. On a single cat exhaust, a cat would need to be welded in the exhaust tubing just after the header.

RebelRacing

Thanx guys,
I guess I should look at the exhaust first as it is usualy the problem with imports. I'm going to look at some headers and cats before I go spending $$ on cams and stuff. I also like the idea of porting a stock manifold...I'm just worried about passing the "Ontario Drive-Clean" program...much like California!

Has anyone seen a header with a CARB number for the Protege?

Thanx again!
