So i am just tired of the many issues that my fuel system has. Frome the tanks to fuel lines to mechanical pump to my carb to my throttle cable. Most of the issues im sure started with old fuel and dirty fuel tanks. My fix is to just remove the whole system and start all over with new lines and cleaned out tanks and obviuosly new fuel. Then i started thinking, why not go with fuel injection. So i went to summit website and researched fuel injection systems and they are not cheap. Of course this lead me to think well why not just replace the whole engine for one of these new gmc v8 that give me alot better gas milage. I can get the whole engine with computer and wiring harness for about half the price as just an after maket fuel injection system. The new engine would more likely be mated to an overdrive auto tranny. So based on amount of work or best bang for the buck what would you guys recommend? The 40 is going to continue to move more towards daily driver with the occasional offroad outing.
Im going to be going away for work and was thinking of dropping it off at ipor and have them do the work for me.
 
^^^What Keefer said! If you want efficiency, and still have the power band for offroad - go with a diesel. Of course, that isn't going to be a plug and play (read inexpensive) swap. Talk to Lance at IPOR and tell him what you want and your budget - we hung out with those guys some at GSMTR and I'll send any business to them I can in the future. Great group of guys there!!

If you go diesel a 6.2 can be had for cheap and has no electronics. It fits the same adapters as any sbc.
 
I agree. Go with a diesel. Yes one of the new GM V8's would do a good job and net you some pretty decent fuel mileage. Probably in the general vicinity of one of the old 6.2 and 6.5L diesels.

Shoot me a PM or e-mail. Just wondering which BN/CO you ended up in.
 
I am looking for reluability but when it comes to diesel swaps. Most shops will charge an arm and leg. They might be justified but i just havent researched it enough to know the price range of someting like that. Honestly though if im going to go to through the trouble and spend my money im going to want newer technology. Hence why i was lwaning towards the new vortec v8s.
 
A 6.2 and 6.5 diesel should be no more harder than a sbc for rebuilding it.

Heck for $800 on ebay you can get a H1 military take out with only 40k on it.

If you go gas... get the 5.3 out of the newer trucks.
 
Those h1 engines would be the last thing i would buy. Even at 40k miles most of those hummers have seen some hell. With zero maintenance i might add. No thanks. Maybe a diesel out of a recked newer dodge though.
It would be convenient to have one type of fuel for both my f250 and the cruiser but i dont think its in the cards.
Anybody know where i can find info or build threads of diesel swap into a 40? Isnt there a shop in colorado that does these type of conversions?

Thanks for the info
 
I would definitely recommend going with a late model GM fuel injected V8 gas engine. It will be much more efficient, more powerful, more reliable, and weigh less than the inline 6 cylinder. I think you'd be disappointed in the power of a diesel, plus you would have to put up with the noise and smell of it.

That being said, there are a few things to keep in mind if you do choose to go with the late model gas engine. It's true that you can buy a complete take out engine with wiring and computer for around $800. But you also have to factor in a new wiring harness for the engine or having the stock one reworked, flashing the computer, possibly a new radiator, possibly running headers because of tight manifold clearance on the chassis. A Painless Wiring harness for the engine runs around $700, or reworking the stock one costs about $300. Flashing the computer is a couple hundred dollars. Nice block hugger headers are $200 to $300 a pair, a good radiator is $200 and up.

I put a 5.7L Vortec into my FJ40 with a Painless harness. That harness was great, everything labeled and easy to install. The manifolds were very tight on the frame, I should have used headers. I am currently putting a 5.3L Vortec in my buggy project. I'm having Jim's Performance in Maryland rework the harness and flash the computer. I'm also running ceramic coated block hugger headers due to tight clearance issues.

Not trying to scare you off, just making sure you know the facts. You will not be disappointed in the power from these engines!
