Xcessive intake mani in a KA 510

[nustad]

I have an S13 KA24DE I'm rebuilding and installing in my 72' 510 4dr.  Just wondering if anyone has used an xcessive aftermarket KA manifold on a 510 swap and how it worked out.

Are you going turbo?

[EastBay521]

don't do it unless turbo

[nustad]

No turbo.

[DISLEXICDIME]

Are you doing high comp?

[nustad]

Nope. Just rebuilding to stock.

[datzenmike]

Only reason is if there is a clear improvement in mileage or performance. (or both) Talk is cheap and a maker can claim anything they want.  So before shelling out your cheese make sure your not buying into the hype.

[nustad]

Hmm. I take it no one has done this yet.

[datzenmike]

Nope. Just rebuilding to stock.

 

From what I see of them they are designed for running motorcycle carbs or throttle bodies. This wouldn't be stock. Is this your aim? If so, we have a thread on R-1 carbs and manifolds, surely someone has thought of running this on a KA-E or DE

Not interested in motorcycle carbs or tb's.  I was just going to run the excessive plenum/intake instead of the stock.  I think the excessive looks cleaner but in pics on a 240sx it looks like the plenum is to far forward (towards front of engine) to route the intake on a 510.  Pic -

I just found this pic of a godspeed manifold in a 510 which from what I've read is almost identical to the xcessive.

Looks like there could be an interference issue with the upper inlet on some radiators.

[Laecaon]

Why bother? Its WAY overkill for anything but a turbo motor. It flows so much better that its better suited for high rpm and forced induction. Sell your piece of art, and make some money.

 

You would probably be better off with the stock mani and the Z32 Throttle body.

[Just Joel]

Looks way cleaner IMO but I've always hated how the intake rakes across the engine bay.

[datzenmike]

The stock intake is curled around and down to lengthen it. Long runners take advantage of the free torque from the ram air effect at lower RPMs.

Here is how I am going about it.

i have a xcessive manifold that i will use on my 510 getting the KA24DET  i still have not fully installed it but i can say that if you are not planing on making over 300hp to the wheels dont bother with it mainly do to the fact u will need to get a top feed fuel rail, the stock injectors/rail will not fit on it . and use bosch style 14mm top feed injectors. so you will need some kind of managment for them.BUT the xcessive manifold fits  better on a 510 going N/A. the throttle body is about 1 inch pushed forword and about 6 inches up higher then stock location. so it will fit with custom air intake. but with turbo from the TB to a FMIC is so close it makes it a problem. i can see why in the pic the guy decided not to use a Ic.     

[DISLEXICDIME]

if you Go THE God Speed Rout Make Sure you Clean Up All The Flashing INSide THE Manifold AND around where the injectors seal

[datzenmike]

Here is how I am going about it.

 

I would route that intake pipe away from the hot rad air and run the air in from in front of the rad. I know they run better with a long pipe between MAF and throttle body so run it straight out past the rad, elbow and ten across the front of the rad and to the MAF. EFI will compensate for cooler denser air and give more free power.

[nustad]

Thanks for the input going to use stock manifold for now.  

[HAM8URGER]

Here's mine

 

 

Mocking everything up it appears that we are going to have to make a custom pie cut pipe in an "s" shape or curled shape running from TB to IC. It's going to be tight but should work

[Stoffregen Motorsports]

That's going to be tight. Are you going to have to trim the plenum to relocate the throttle body? Looks like it from here.

[HAM8URGER]

It' should fit. This angle is deceiving. Worst case scenario we will have to weld a 90 directly to the TB.... Not that big of a deal

[DISLEXICDIME]

Do your ic pipe in a downword spiral
