AMMFab Ported Long Runner Manifold, 2.0L / 2.4L NA DOHC
Model Number: 221115-LONG
If you have a 95-99 Neon with a 2.0L DOHC engine or 2.4L swap with all the bolt ons, high compression pistons, head work and or cams, this is the one magic item you need to complete your build.
Back around 2010, we had a high compression 2.4 engine with cams and long tube race header in one of our Neons. We had the 2.0 DOHC stock manifold with throttle body and were making 170 hp and 170 torque at the wheels with no tuning.
With swapping over to this manifold, because its optimized for horsepower and not lower end torque like the 2.0 factory DOHC manifold, we gained serious top end power. We saw 194 wheel hp and torque was unchanged. Instead of power nosediving after 5500, we saw a much higher plateau. It was very much worth it!
These are made out of stock 2.0 manifolds that are cut, and then welded to new lower aluminum manifolds. They can be used with stock throttle bodies however you really should use a ported stock, or a 60mm tb with this. You'll also need the longer 98/99 Neon throttle cable for this as well.
No tuning needed, bolt it on!
Map sensor location is on the back of the manifold
Other vacuum ports on back of manifold for your other vacuum needs. Either use a brass nipple from a hardware store, or block off unused ones.
Ready to install, just buy a new intake manifold gasket!
No core needed, buy this manifold outright!
AMM can take a LONG time to make these, this current batch took almost 1. 5 years from when we sent them to him for us to receive. So, its kind of a big deal for us to have these in stock. If you ever wanted to get one of these, and don't want to wait 1.5-2 years to get one done, this is your chance.
