Custom 5SFE Intake Manifold Project Options

[doory100]

Finally getting the intake welded together. starting to look good!!

the velocity stacks I made don't look to bad...

[doory100]

I have run into a problem. My intake fits but the plenum is right against the fire wall. I have not welded the plenum onto the intake just yet. Im wondering how far from the fire wall it needs to be? Im about 2 days from scrapping the whole intake project!!

Depends how solid your mounts are. Get a big wad of Playdo or similar modeling clay and put a big wad on the back of the intake manifold touching the firewall with some cardboard under it (so it won't fall out) and go for a spirited drive, see how much smoosh there is and then add 20-30% to that figure and you should have a distance.

Not sure how close yours is but this was the 3sge in my corolla, I had a rear solid poly mount and a front rubber filled poly mount. It never hit. Also you can maybe put a stopper on your motor mount if you don't want to damage the manifold or maybe change the radius slightly.

Here is my new clearance.

I'm modifying the intake and I need some thoughts
Is this to big or should I go with this ?

[Bitter]

Do some math on plenum volume, runner length, and the RPM you want peak power to be around.

[doory100]

Went with a new plenum!! Looks awesome!

[doory100]

Does it matter where the breather spout is located? Example: after or before the TB?

[rdyzz]

Kinda cause one provides just filtered air while the other provides vacuum.

[doory100]

I have found a use for it

I have been looking at a similar thing for my project build, but was thinking about a side feed centre feed inlet manifold.......if that makes sense, a bit like the one in this picture, but with the inlet part veering off to the passenger side.



See if I can figure out a way of doing it......need to break out the calculator.

hopefully it will be painted by tomorrow

please delete this thread. the intake was a bust!!!

[richee3]

No need to delete it. How was the intake a bust? Let's keep this thread open and keep bouncing ideas around on how to improve the intake.

[doory100]

the pipe and the TB together were inches away from the distributor. It was not on the car and i forgot it was going to be there. plus it should have been closer and taller. I really wanted the 2.5" TB and the intake to work. I just dont have any time to go back to the drawing board.

[rdyzz]

I would still keep it in case you do have some time in the future. Its also nice to have something that only needs slight modification to have work.

[doory100]

Is this a waste of time or should I go for it? The runners look a bit to long! TB does not clear the firewall

[doory100]

Intake is done and ready to go in tomorrow... I hope!!
Going to repaint the intake body after the Celica stencil dries.

Using this weld to add pems for the bolts. Works incredibly well.
