I bought the following for my 92XJ with the HO i6: http://www.ebay.com/itm/150986520459...S:3160&vxp=mtr

One of the best upgrades yet.

I have heard that you can use injectors out of a ford 5.0 and it will give you more power.

Just in case you hadn't planned on it, I would replace all of the injectors at the same time. It is likely that just the action of taking the fuel rail off will cause others to start leaking as well. There are many good replacement injectors that you can get for a reasonable price, one option of which is the Neon 703s as mentioned above.

For a Renix DD Bosch # 0 280 155 746 from a Volvo 960 2.5L & 3.0L 1991-1998, or # 0 280 155 702 works good.

Nah. Smoother idle is about all you get. Mileage doesn't increase either.

The HUGE issue with the REnix era injectors is that they can leak fuel externally from a seam, spraying raw fuel on the manifolds resulting in fires.

The later injectors don't have a crappy seam like that and also have 4 holes in the tip rather than one like the Renix and atomize the fuel better.

Programbo here on CF is quite knowledgeable on which injectors to use for which application and supplies refurbished ones also. No guesswork.

I would upgrade the injectors. 4 holes vs 1 hole. There is misconception about more power and better fuel mileage. I don't think either of those are increased. I do say that the throttle response is alot better. Better throttle response can feel like more power but its not.
