Need More Power

Postby eastcoaster91 » Tue Nov 17, 2009 4:06 am

Hello, I have a 1990 Isuzu PuP 4x4 2.6l gas/petrol it has 169,000miles, from what i have read up on it that this engine baselines at 120hp so im looking for cheap power adders. Im thinking bigger injectors, k&n airfilter i was even thinking bout finding a turbo, but im not sure bout it have 169,000 miles. i know that these motors last forever like my dads 22r toyota that has 314,000 miles, so if you have any thoughts i would like to know


Thanks Kevin

since you are in the usa and there so easy to get i say do a 350 chev swap out. gas or diesel there both good choices and will pull any thing. the diesel chev respondes to turboing well to.

chevy V6 conversions were popular a few years ago. Some Troopers and Amigos had a 60 degree chevy v6 as standard. Hunt down a wrecked one of those and get the trans then fit a 229 or 263 CI 90 degree v6. The 229 has a carby but the 263 is injected.

If you cant afford and engine swap then you cant afford a Turbo install. To reto fit one you need the turbo, manifolds, intercooler, clutch, exhaust and then a new engine management system with dyno tuning etc.

As Geeves has said there are cheap engine swaps that will give you an immediate boost and still be reliable because the vehicle came out that way from factory.

Otherwise the only cheap power ups you will get will be freeflow intake, freeflow exhaust and good tune up!

All the best
Matt.

To go more than 3 or 4 pounds on a high compression motor you need to do major mods. ie low compression pistons if available plus lots of other expensive stuff.
If you can rebuild the engine with less than 8/1 compression a turbo could be a way to go but without this the gains are not big

Bet you have plenty of parts for a V8 over there.......
I'd just give it a good tune and put up with it, save hard and get a V8.

People Ive known who had that engine in Troopers told me it would do 100mph/160kph.
what more could you want. First time you hit the brakes in one of these at that sort of speed you will realise it was a bad idea. They aint race cars

I like extra horse power as well, but not for high speed, you need it to clear mud tyres, and it's always fun to show who's boss at the lights :twisted:

Anyway there are a lot of things you can do to a petrol engine, like extractors and exhaust, cam regrinds, porting/polishing/shaving the head, intake piping/ bigger filter, and injector re sizing. But that's going to cost and if you later want the turbo, it would need changing.

There are a lot guys in Australia that do the mini truck thing with the Rodeo/Pup, that has this engine and also the Gemini guys turbo them a lot.

Check out the Auora swap and it bolts to the 4L30E trans. Just as long as you don't over rev the engine the trans will hold together/

It is basically the Cadillac Northstar engine built to about 250-260 HP. You can even tos in a Caddy Northstar with 370 but the trans will probably implode or explode depending on how hard you push it unless you seriously beef it up.

Either way, the performance enhancement will need the computer from the car it came from to meet smog requirements just so you know.

I am considering the Aurora swap myself and having the trans built to handle the increased power/torque.

I had an Aurora and it was great on gas btw used to get ridiculous MPG out of mine. HWY was well over 30 depending on how I drove the car.

you mean this engine?

The LX5 V6 is a DOHC engine from Oldsmobile, introduced in 1999 with the Oldsmobile Intrigue. It was produced by the Premium engine group at GM and was thus called the Premium V6, or PV6, while it was being developed. It is based on the L47 Aurora V8, which is itself based on the Northstar engine, so engineers called it the Short North, though Oldsmobile fans have taken to calling it the Shortstar.

It is not a simple cut-down V8. Although it has a 90° vee-angle like the Northstar and Aurora, the engine block was engineered from scratch, so bore centers are different. It has chain-driven dual overhead cams and 4 valves per cylinder, but is an even-firing design with a split-pin crankshaft similar to the modern GM 3800 engines. The LX5 displaced 3,473 cc (3.473 L; 211.9 cu in) and produced 215 hp (160 kW) @ 5,600 rpm and 230 ft·lb (312 N·m) @ 4,400 rpm. Bore is 89.5 mm (3.52 in) and stroke is 92 mm (3.6 in). Compression ratio is 9.3:1.

The cost of building this engine was high, and it was not used in many vehicles. It was said at the time that a family of premium V6s would follow, with displacements ranging from 3.3 L to 3.7 L, but only the LX5 was ever produced. It was entirely different from any other V6 in the GM inventory, and as with the Aurora V8, production stopped with the demise of Oldsmobile.
Year Model Power Torque
1999–2002 Oldsmobile Intrigue 215 hp (160 kW) @ 5600 rpm 230 lb·ft (312 N·m) @ 4400 rpm
2001–2002 Oldsmobile Aurora 215 hp (160 kW) @ 5600 rpm 230 lb·ft (312 N·m) @ 4400 rpm

The 3.5L LX5 was on the Ward's 10 Best Engines list for 1999 and 2000.
