here we go
supplies used in this project

here we have our shity used stock intake from egay

look at the chip on the top part of the im opening

60mm stock im opening

we establish our goal excuse the flower shorts it was hot this weekend

intake straped down and ready for the grindage


time to dig in

i found this drill bit in my garage made the grindage go faster its 36 grit

time to go to town with the drill

keep in mind im doing this as evenly as possible constately measuring

took a pretty good chunk outa her

take down all uneven surfaces to reduce friction

keep in mind im using a 36 grit sanding wheel i only used one the whole time which suprised me

almost there

our established goal was too big for this intake so 63mm will have to do

more pic of polished finish soo too come

i got a little lazy wit the pics and i didnt take pics of the polish and cleaning process
after i got to my goal of 63mm with the 36 grit sanding wheel i used a 60 grit sanding wheel on the dremel to smooth it out and then i used 120 grit sanding wheels to smoth that out....during the smoothing out of the intake i took off as little material as posible since i had already reached 63mm

remember the chip on the tip part of the im opening ....it is no longer there


the poilshed finish is no work of art but it sure is smooth trust me




i cleaned up the runners with 120 grit sanding wheels just to smooth out the roughness and then polished them



i used intake system cleaner on the whole intake and then a wire wheel on the drill and steel wool to get to the hard to reach places to clean the exterior of the intake

sorry about the huge pics

dek1mfk

looks good, does it measure the same all the way around?

Did you put it on the car yet? If so, did you notice a difference? What size throttle body are you using with this?

rockofcali

yes its almost the same size all the way around no its not on my car yet ima put it on this weekend ...gotta get ta school and work ya no lol
heres the tb im using i forgot what i ported it too but i no its not big enough so ima see if i can over bore it to 64mm in my eng rebuild class

update on progress

mrnicolas

just to let you know, that is not a chip on the intake manifold. that is supposed to be there from the factory.

I have two different year ls mani's, so I guess I need to look for that.

how much would this actually help?

It looks like you just ported the outside edge of the throttle body, is that what you did?

Im going to be installign a turbo kit in a few days, do you think doing this to my gsr manifold would benefit me at all?
It's a stock manifold, and I'm not tryin to make a billion horsepowers

rockofcali

that tb is tapered to stock im trying to see if i can bore it to 62-63mm if not im going to put the intake on my car and use that tb till i get a bigger one, porting an intake is almost pointless unless u have a bigger tb not too big tho too big will mess up ur air valocity unless its boosted even then u dont want it too too big

Yes that "notch" is def there stock, but what point does it even serve?
It only looked like it catches "gunk" in that spot, and nothing else.

Do you think the current hole for the TB mount is centered where the old hole was? I can see from this picture that it is not perfectly round.

I would be extrememly difficult to do that well with the equipment that you used.

rockofcali

can u rephrase that question i dont understand wut ur askin....the tb hole hasnt moved anywhere....are u askin ff the tb bore lines up crooked with the im bore? if thats ur question then yes but that dont matter b/c the tb bore is smaller then 63mm

Dogginator

That was essentially what I was asking. Ideally, the TB bore would match the IM bore. A matched bore minimizes the flow restriction.

rockofcali

yea i no that but its not really restrictive if the tb bore is smaller then the im bore.. im pretty sure the stock tb bore is 58mm while the stock im bore is 60mm

looks pretty good
