2003 Diesel engine swap.

[Wanganator]

i have in my possession a 2003 5 peed 4 door 4x4. i also have a 98 3.1 liter isuzu trooper turbo diesel with around 60,000 miles on it. im kinda feeling a diesel conversion is coming. i already did it on the trooper. i know every thing that has to be done already, the radiators inlets and outlets are in the right place. the power steering res is on the correct side. and i got a shop right down the street that will build the adapter plate. the air cleaner is on the correct side. ill have to re route the clutch line, extend starter electronics , modify throttle cable, and get a rpm modulator from dakota digital. alternator on diesel is on top of engine too (no more stupid dead alternators)! !

specs on 4jg2: 95.4 mm bore x 107 mm stroke
112 hp at 3,600 rpm
192 lb·ft at 2000 rpm
(pump has been turned up, but these are stock specs)

specs on vg33e: 91.5 mm bore x 83 mm stroke
170 hp at 4,800 rpm
202 lb·ft at 2,800 rpm

isuzu gets about 27 mpg on interstate with 31x10.50x15s. nissan weighs less than the isuzu. with that diesel and the high gearing of the gas nissan transmission we are talkin some serious fuel mileage.
what do yall guys think?

Sounds cool. You should check Colorado's diesel emission testing to see what's permitted if you haven't done so already. A small number of states have started testing car and light truck diesel emissions that they used to expempt.

Sounds like a real cool idea!! Good luck!!!

check emissions first, but it sounds cool.

lots of people talk about engine swaps, but few actually do it. i'd like to see this and it sounds like you have the parts and ability.

[Kamikaze]

That would be awesome if you managed to do it.

well emissions isnt a problem cause my truck is registered in bowie county, texas. as long as a diesel has a muffler, it passes. The trooper is registered there too, iv put over 10,000 miles on it since the swap, no problems at all. But i think id rather sell the trooper (only post-91 european spec trooper in the usa) as a whole, then just buy another 4jg2 without transmission and transfer case. and i sure do appreciate that gas is only 3.50 and diesel is a whopping 4.30. im gonna do the sea foam thing and see if i cant get my mileage back. its at 17.8 now city or interstate. stock tires. i need 21 consistently to make it worth keeping the gas engine.

Illegal unless you can prove that engine came in 2001-2004 Isuzu troopers.

It's a Federal EPA thing.

[Wanganator]

speedfoos its been registered for 2 years now, saftey sticker every 12 months. emissions and all, no problems. may be illegal in big cities, but not anywhere im ever gonna register it.

[speedfoos]

I don't doubt that you've been able to make it work and have been able to get it to pass emissions locally, just pointing out that its a federally illegal swap. Wouldn't be the first, won't be the last.

Have you ever heard of anyone actually getting prosecuted for this?
