Thread: Side feed or top feed

I'm putting back together my avenir motor just need some advice what would be better side feed or top feed.

Both are good. Most Nissan guys tend to go side feed due to the simple fact that the OEM fuel rail can be used. Now with top feeds you have way more options and the injectors are usually a lot cheaper in cost. Only down fall is a custom fuel rail is needed unless you buy a off the shelf brand rail.

I for one prefer top feed injectors.

What about a GTI-R fuelrail? Or am I saying something completely stupid?

It will only work on the Pulsar manifold.

Ok cool I'll go top feed, but what modification will have to be done to it?

You will need a fuel rail. I would go top feed as well. They tend to have more options.
