HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

LS Engine sourcing

Post  endrnet on Sun Aug 16, 2009 12:33 pm

Anyone have suggestions on where to source an LS motor, and the risks associated with the various options?

Promarengine seems to have LS1/6 longs for around 3k chickens, a new crate from Jegs is about 5.7k chickens. I've seen various [more dubious] engines in various states of mileage and/or disrepair on ebay and craigslist. Those cheaper alternatives might "work" but might have problems that would eat my project time and add costs that are not predictable.

I'm not interested in a stroker or crazy HP engine, my focus is reliability and maintainability. I had a stock C5, and the 944 is several hundred pounds less curb weight -- I don't need any more HP/TQ than a stock LS1 to be *quite* happy with the result.

Thoughts?

PS, I am not soliciting for offers or offering anything for sale (forum rules), just discussing the various options that exist for my... 944 LS swap project. Maybe everyone buys crate engines, but their cost would probably delay my project by many months while I hide some chickens from the wifey.

Thanks.

I don't have a good source for the engine, just want to give a little advice. Make sure that you get one that has not sit for a long time. I have numerous motors that I have dealt with that have sat and few problems happen. mostly stuck injectors and other sensors. I did get one from a junk yard "That was just pulled", The guy's at the yard had pressure washed it and filled 2 cylinders full of water. Then the "just pulled " motor looked like it had sat for a year and rusted holes in the cylinder walls.
Just my 2 cent's

Chickens? ..... All the hookers on craigslist take roses. Are chickens the same thing?? lol


Also, I believe it just depends on what you want out of your car. A crate engine is nice because its brand spankin new, but the downside is you have to then buy everything separately. You need the acc. drive kit, wiring harness, ECM....

A pull out engine might have some miles (or a lot depending on the one you buy), but everything you need for the engine is already on it. These are all over the place. Ebay, craigslist, LS engine forums..... LS1's come out of the woodwork.

I still haven't actually decided on my route either. It becomes a tossup between a pullout and rebuilding it, or just starting from scratch. For your needs though, I would think a low mileage pullout is by far the best option. They're all over Ebay right now. Some with 25k miles, and $4k.... no contest.

I forgot to add, Unless you have money to spend. Buy a complete pull out. When I say complete, I mean one with ecu, wiring, accessories, and every nut and bolt you can get. If you buy one without, you will spend a ton of time and money chasing parts. Trust me I have been there done that! No

Promar got back to me and pointed out that without a core, it's another ~1k. Which brings the "discount option" of a reman LS1 within 1.8k of a new crate (and the reman won't be as fully dressed). And I saw an LS2 on ebay, new crate, from a dealership no less, for 4k, which is the *same* price as the reman LS1 with core charge.

I'd say that the LS engine market isn't very efficient in the economic sense. I think you're right, a pull out or new crate is the only practical way to go.

This one has my attention. GM LS3 480 for 6500. Shopping around seems to make a big diff. Jegs and Scoggin Dickey want about 2k more for the same pn. The pedal, harness and ecu kit is about 1k. This doesnt have any accesories or mounts. What do you guys think?

Your gonna have to loose the pan and exhaust manifolds. Some guys use the manifolds for emission reasons. You still need the maf and o2 sensors and alt. and mt. Starter also. A pull out might end up more economical if you hear it run. If you go pull out, think about time to build for warranty reasons. I've been working on mine since june. Hope to fire it by labor day.

944ls,
Remember that the little pieces will nickle and dime you to death. Heck, you might look a round and find a low mileage complete wrecked car for few more bucks.
When you do your conversion there is a lot of little things that are needed that no one ever really talks about. Hoses (all, not just radiator ) bolts, brackets, wiring related things, and many more. all these thing eat away at our budget.
Now, if you have no budget then your in great shape!
Very Happy

I understand about the nickle and dime and "nobody really talks about," items. I keep hearing that ECU/PCM and wiring harness can kill budgets, but every time I hear about a gadget like that I look it up on ebay and find that they are available for very reasonable numbers. Certainly nothing pricey enough to overwhelm the 2k price difference between used/new.

Lots of people seem to be parting out wrecked cars, but the LS sourcing itself seems to remain the "big decision." My concern about a wrecked car pull out is the same concern about a used car. Who drove it, how was it driven and maintained (after all, the guy/gal wrecked it). With new-manufactured motors within 2k of the pull-out/reman, it seems silly to take the risk on the core of the project. I'd rather have a NEW engine, and get reman accessories that are bolt-on easy-replacements if they suck, than try to save 2k and maybe need a bunch of engine internals machined and balanced in order to have a reliable motor. Perhaps I'm underestimating the list of "stuff" that a crate engine "also needs" to run?

My friend in the know about motors say that nothing will beat the power and reliability of a fully blueprinted engine where you send 50% of the parts back because they're 1/10,000th off spec. He also tells me that if I'm not doing major mods to internals, the sense of it is nil, go crate. What do you guys think?

I did see a couple other acc packages, maby truck vett or fbody I am not shure what fits best. I will not need a ps pump but would like to have ac. I have no idea what alt and compressor will work with the ecu. Custom fab mounts are not out of the questian either.

As far as the Throttle by wire, I would nix the throttle body and get on from an F body. Way cheaper and cleaner install than all that harness. Just a quick cable setup and your done.

Drive by wire is a lot easier than it looks/sounds!! Works fine and allows you to have cruise control without a whole lot of cables and pulleys. Just make sure you have good electrical drawings (check out alldatadiy.com). I was a little intimidated at first, but I am happy staying with the DBW setup. If you have questions, feel free to ask!!

The GMPP website listed a local dealer selling the LS1 crate for 1k less than Jegs, and the 5.3 long block for 0.8k less than promar reman of the 5.7. The LS1 pricing mystery deepens.

Engine Sourcing

Post  968gene on Mon Aug 31, 2009 6:43 am

I used car-part.com and found several L33's within 3 hours of me. I purchased a 2007 complete pullout with harness and computer for $1,700. It has 6,000 miles. I found two others with less than 12,000 each. This engine has been referred to as the "baby Z06" because it has an aluminum block and uses the same head casting, but different valves. In the 2005-2007 chevy 4x4 extended cab trucks, it made 310 HP stock. An ECU reprogramming and it should do much more. Add a cam, headers, etc., ...well the hot rod magazines are full of 5.3 truck engine stories pushing 400+HP. MUCH cheaper than a LS1 build.

Hmm, it seems there are several of those near me, albeit with more miles. 30-40k miles and ~1k chickens.

I am liking the selection of L33s in my area. Will the accessories work in the 944? To my understanding, a Camaro accessory package is what I should be looking for, but by all means, the L33s are definitely cheap enough and will do what I am looking for.

L33

Post  968gene on Tue Sep 01, 2009 2:14 pm

I feel this is the best-bet engine for the 944 swap. I had to pass on the 6,000 mile motor and go with a 11,000 mile motor for $1,250. I pick it up Friday!
I am getting the truck harness (everything under the hood install) and I will run the F-body accessories. It should be a bolt-on kit type install. The yard I'm dealing with will let me pick what I want to go with the engine.

Yep I just found an L33 with 10k mi on it at a local salvage for $1300 (including the $100 core charge). The poor truck got rolled down a hill or something.

Where is anyone getting performance parts for the L33s?

Heads swap from an LS1, but do the cams?

L33

Post  968gene on Tue Sep 01, 2009 4:54 pm

the L33 shares head castings with the Z06. The cam is hot as well. change the intake to a LS6 along with a larger throttle body and a dyno tune and your done. maybe add a set of beehive springs for high RPM sprints. think of it as a 327 cubic inch Z06.

Most, if not all, LSx performance parts are interchangeable. On my L33, I've swapped in a Z06 cam and valve springs/locks, LS2 intake manifold, TPIS 90mm throttle body, and Melling water pump. Have larger injectors waiting in the wings, but that's for a much bigger performance part still under wraps (no, not a turbo).

I would advise against swapping in LS1 heads. The LS6 heads on the L33 are great. They have the cathedral intakes and D-shaped exhaust ports which flow much better than the LS1 ports.
