when I went to the junk yard I got mine off two dodge neons. Make sure the last numbers are 703.

By the way how do you test to make sure the injectors are working as advertized. I think I might have a slight miss after installing them.

Well, gonna attempt to get 5 more on Monday.... if someone could post a link to a rebuild video for the injectors that would be awesome! FYI the caravan injectors are so fricken hard to get out, you basically have to take then entire engine apart lol go for the cars!

Stealing your idea with painting the fuel rail, just btw.

One last thing, where'd you get the k&n filter for your valve cover?
I know this is a little late, not sure if it was answered anywhere else in the thread. However, in case anyone else was wondering about the crankcase breather I believe it's K&N P/N Part #: 62-1220, because that is the only push on one they make.

I've always wondered what exactly is the advantage there vs stock?

To be honest I have no idea, I think that some people use the K&N style filter when they move their air intake or install an aftermarket air intake.

Im about to clean and put the new filter baskets, o-rings, and pintle caps on the injectors and I wanted to make sure if it is ok to clean then using the carb cleaner method with the syringe manifold.

I picked up some syringes at CVS and a can of carb cleaner and read a couple things about not using carb cleaner or using one with no methanol and now am second guessing the process.

So carb cleaner ok or no good?

Ya I just went for it today. Sprayed carb cleaner through them and put new orings, baskets, and pintle caps from the rebuild kit I bought that is linked in the first post of this thread.



My exhaust manifold is being delivered tonight by UPS to replace the cracked manifold that is on there.

I might pick up a 99+ intake if I can get one for $100 or less.

Ill post up how she runs once I get around to the install.

I didnt end up getting a 99+ intake manifold I got outbid by $1 on it. Possibly by someone on this forum... lol

My final verdict on the 703s is totally worth it IMO.

I had the injectors and rebuild kit around here for a while and I should have done the swap earlier.

No it doesnt make the 4.slow necksnappingly fast (especially with my 31s and 3:55s).

I did notice a little bit smoother idle, smoother and more throttle response, I think there was a little power increase, and most importantly it can go uphill and feel like it has at least some power and doesnt need to downshift to gain 2mph going uphill. This was HUGE for me since I live on the base of a mountain range basically, 50% of my driving is downhill going and 50% uphill and I hated how gutless my ZJ was going up a grade but now its a bit better and that makes me happy.

I paid $35 for 6 injectors and a pigtail and I think like $18 for the rebuild kit. I say its worth the time and money for the swap. I was in there already replacing the exhaust manifold but if you are just doing the injector swap it could easily be done in under an hour even by an inexperienced wrencher.

BTW I have 2 extra 703s that have been cleaned and rebuilt with new orings, pintle caps, and filter baskets if anyone needs a couple shoot me a PM.

I recently swapped in the 703 injectors and I'm happy with it. I got the injectors brand new (all 6) on ebay for $80. The swap was super super easy. I have also noticed a smoother idle, but I also recently cleaned my TB and IAC and replaced plugs, wires, and cap. I just bought a 2000 intake manifold off ebay, so when I get home in May I'll install that which im pretty excited about.
