Since you just have a bolt on 5.0, porting probably won't be worth that much.

Also, $150 is a pretty good deal if the guy knows what he is doing.

To do a decent porting job, you need an air compressor, a die grinder and a bunch of sandpaper rolls or other grinding bits. You also need a place where you can make a whole lot of noise, because the grinding and compressor can be very loud.

Also there is the risk that you could dammage the intake beyond repair. Some people know when to stop, others just blast through things untill something breaks. If you are a competent DIY kind of guy, it shouldn't be much of a problem.

Seth...I just got done doing my Explorer...this also has the same GT40 lower as the Cobra....Theres really not alot to port on the lower....if you look down all your runners you wanna see a straight shot to the head port....check all the ports and you'll see maybe 2 ports that the "curve" in the runner may be a restriction...just lightly grind the sides to "lessen" that curve you see....like i say, Tmoss did my Ex lower and barely touched but a couple runners....

the upper will support your mods no problem....only thing i did was to color around the u/l ports...lay your gasket on there lining up you bolt holes...tape the gasket in place if need be, take a fine point and "scribe a mark around the gasket..remove it...then grind to your "scribe" line to gasket match it....very simple....

Port your TB opening to if its not a clean shot thru...

if you want you can take some sanding rolls and clean up the "casted" finish some....do that all around....dont go crazy removing material...just smoothen them up some...go to standardabrasives.com check out there kit for like 26.00...thats all youe need to clean it up some....
air tools are a must far as im concerned....

the above is prolly not worth alot, other than the fun of doing it....makes for a smoother airflow i would guess....i do this to all my intake ports...send me a pm and i can forward tons of pics on porting...

polishing...screw that..i ain't got the patience for that...

Seth (that's your name, right?),

Tom Moss will do it for $120 shipped, he's doing my GT40 lower right now. I'm only having mine ported b/c I'm getting new heads and a cam. So you may want to wait on yours.

RC , this intake is from 93-97 Probe GT , my brother have 96 and If I get done my intake I gonna try with upper brothers , but this one is too hard to do it

I saw that, I just meant "what is that intake" meaning I have not seen it before, and it just looks strange seeing it on this board.

I became dizzy after reading the opening paragraph, and I had to go take some Dramamine!

Good luck Seth

are this Intake's cheap or what and can I use this spacer for Cobra ,Explorer and GT40 intake and which one is better

 

[yellow5.0cobra]

Dont take too much, as you might just break thru and have a nice hole.

Take your time and dont over do it.


Also why are you so intrigued by the Cobra Intake?
There are PLENTY of aftermarket intakes that are much better than the COBRA. And not THAT expensive(add $90 for t/b elbow)

Guys what is better 94-95 Cobra or 94-95 SVO intake , I think thats same thing but which one looks better and what you think about this one http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=36474&item=2457412708 , is 300-350 bucks good deal

Because if I put aftermatket intake , I have to take out strut brace and mey be cowl hood

 

[red94fiveo]

I don't know of too many aftermarket intakes that won't clear your stock hood (assuming you aren't using a spacer). As far as the strut tower brace, plenty of guys run without one. I think the edelbrock is the concensus intake around here.

 

[yellow5.0cobra]

Strut tower brace?

Unless you do some serious road racing, you dont need it.

Cowl hood?

No. Just dont use spacers.


If you cant afford a new edelbrock intake, you can opt for the TYPHOONS, which are almost identical and half the price. I pointed them out to you before.

 

[YEAHLOH95]

even with the cobra you will still need to replace or remove the strut tower brace it won't clear the cobra they did not come with one .i had a cobra on my car before the trick flow and i really liked it but it did not match up to my new heads as well as the trick flow lower does .

Seth, on the one hand you will not get the same power from porting the lower intake as a pro, but on the other hand you will get a great deal of satisfaction from "doing it yourself" - so, if you want to try porting it yourself use my basic porting guide at:

Thank you tmoss , thank you a lot
Anyway are you the one guy who do port and polishing job ?

 

[tmoss]

Yes I am. By the way, if you want to check out pricing on carbide burs (you need a air compressor and air die grinder to use my method of porting), go to www.carbidebur.com
