What Fuel Injection Conversion Kit To Get?

Postby TheFlamingHips » Tue May 14, 2019 5:24 pm

Hey all.

I have a 1990 GW and I'm looking into getting a fuel injection kit installed. I did research online and ended up more confused than anything. I have very limited knowledge about the motor for the GW so any help would be appreciated.

I've noticed fuel injection kits range from $600-$3000+. I've seen Howell, Sniper and Holley talked about lots. I also noticed Team Grand Wagoneer dot com was expensive but seemed to include lots of gear I'd need?

My questions are:

What are the best fuel injection kits for a 1990 GW?

Do different kits do different things or are they all doing the same thing? If so, why such different price points?

Would you suggest I get a professional to install this with my limited knowledge of motors, carbs...etc or is it an easy install?

I'd need it to be California legal as I live in LA. Do all kits offer CA legal options?

Cheers in advance.
Ben

Fitech or Holley

Have a mechanic do it with an in tank fuel pump.

I think Howell is the only California certified one but I don’t know I don’t live there and the others may have been added...

Howell is the only bolt on kit that is California legal. You can make other kits legal, but you have to go to a referee station to have it certified.

I can’t understand why California doesn’t make all FI kits legal.

Seems it would make too much sense to have more safer, greener and more efficient vehicles.

If they really cared about clean air and the environment. I’m just saying...

You really should vote them all out.

1: CARB is not voted in.

2: There are valid reasons for having at least some certification for EFI kits.

3: CA is not the only state that requires the kits to be legal.

EFI certainly can be cleaner than a carb. But it can also be less clean. It all comes down to the programming. But the main reason every kit isn't legal is because they have no provisions for EGR or vapor recovery. These are both important when it comes to emissions.

The big issue is what it cost to become CARB certified. If the cost was less, there would be a lot more legal turn key options.

Thanks for the info guys. It's really helpful. I found this Howell one that says it is Cal legal:

Would I still need to take this to a referee station to have it certified?

Nope, CA legal w/ EO# sticker = normal smog testing and NO referee visit.

'88 GW (aka Babywag) '90 GW (aka JunkBucket) both fuel injected.

As babywag said, just a normal smog test. The whole point of having it be certified is that you don't have to jump through any hoops.
