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 …

Nope. Well... its a 6.2 liter engine. Laughing

This threads "issues" are just things that one has to solve when NOT using a "kit". I sold most of the RH kit away and bought the parts that are necessary off-the-shelf. The only thing that I am re-using from the RH LT kit is the uprights.

If you have an LS kit, you probably wont see any of these issues. But I didnt want anymore RH kits; didnt want to pay that premium.

Cool! Thanks for the clarification.

I've got my car gutted to the bone so I was just going to go the LS3 crate with factory controller route. I suppose I'll just make my own headers and use my RH kit for the rest.

As with the harness modification, I was internally convinced that I could not do this mod myself and was anguishing over how much it would cost to have done and who would do it.... but then Greg did it and so I gained a bit of ball mass and went for it. Thanks Greg...the more you post, the more they start to outgrow my shorts.... Laughing Laughing Laughing

I bought the Moroso 20140 steel pan from summitracing. With the manual steering rack, I found that the required notch to be made was less than the power steering cars due to the fluid lines. I used a piece of 16 guage steel sheet from Lowes ($12) and 75:25 CO2/Argon to MIG the notch. To form the notch piece, I used a C-clamp and two pieces of 2x4 as a make-shift brake. After welding the piece in, I turned the pan over and welded it from the inside of the pan for added insurance against leaks. Finally, I ground down the welds on the outside and decided that stripping the pan to have it re-zinced was silly and so simply hit it with chassis-saver (por15) and then a quick shot of silver topcoat. For a show car, a re-zinc would be nice but this car is NOT a show car! Cool

NOTE: Make sure to bolt the pan down in all 4 corners to prevent warping under heat. I did not so this and the pan had a 1/4" warp in it afterwards. I had to heat the pan up with oxy-acetylene and bolt it down to regain flatness; which worked nicely but would not be necessary if I had simply bolted it down prior to welding.

The entire process from first cut to topcoat of silver took only roughly an hour and a half including re-flattening it and making TWO notch pieces (first piece was too short-I didnt account for the bend radius initially-silly me). So dont be affraid to do this yourself. I am by no means a good welder or metal working type....but its easier than one may think.

However, if you do not own a welder or just dont want to or have the time, I have recently found out that 944v8s.com sells the pan WITH the notch already done!!! Not sure if 944v8s' pans are re-zinced or what though...good question. Regardless, I had already ordered the pan before finding this out... C'est la vie!! I believe that I am doomed in that every time I need something, after I get it and modify it, someone offers it already done. Sad Laughing Moreover, Greg has informed me-in a manner that made me feel like I was an idiot for not intuitivy knowing already-that his pans are all bolted to a jig to prevent warping. So, youll know that when your pan arrives, uncharateristically to that of RH quality (PORH), it will be flat, true, and with at most ONE dipstick hole. Laughing Laughing Laughing (if you dont know to what Im referring, this was seen on PHB in that RH commonly sent out warped, sieve-like pans and in atleast one occurance a pan with a dipstick provision on both sides of the pan. Laughing

Glad to help Arthropraxis. Thats exactly why I posted it. I spent sooooo much time searching for the right part at the right price that I decided to try and spare others the pain. Very Happy But, I believe this can all be avoided by checking out our boards saving grace, 944v8s.com, and its full kit. The price is perfect and alot lower than RH and dare I say....better quality and a HUGE customer service program!

I already orderred most of my kit from 944V8s. That list will help with the odds and ends like fuel fittings and such. Most of those items I don't even know the correct name for so I spend hours searching here, the old site and LS1tech. I have learned a lot, but still so much more I don't know.

Hey,

Looks good, I'm about to do my oil pan too so those are encouraging words! From a vette to a 944 back to a vette, that engine's had a pretty good life. Razz

I bought a custom pickup from moroso and the oil pump is new. This LS3 had 2000 miles on it when I bought it. LS oil pumps are not like LT or pre LT oil pumps.

just curious, on the manual brake setup. How much of a difference does using the wilwood master have on the performance of the brakes compared to just running a stock master?
