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 …

1987 944 Turbo --> LS

Post  chrenan on Thu Oct 20, 2016 10:25 am

Hello everyone!  Glad to be here, I've run a 1987 944 Turbo as a street legal track car for the last 9 years.  It's been good to me and I've got it setup to be a perfect dance partner.  I've kept up on engine maintenance over the years, rod bearings, head gasket, fresh head and turbo etc.  A driver side balance shaft leak and a few others have been getting steadily worse, so I really need to pull the engine and address it.  That prompted action on an LS swap that I had been considering for a few years.  But first a little bit on the car, and the pieces that will remain after the swap.    

Front Suspension:

400in/lbs springs
Racers Edge Camber Plates / High Strung 44 Control Arms with monoball bushings
Ground Control coil over / Koni Sport
30mm front sway bar

Rear Suspension:

650in/lbs springs
Elephant Racing Poly Bronze Bearings / Solid torsion carrier mounts and monoball bushings
Ground Control coil over / 30 series Koni
19mm adjustable rear sway bar

Weights:

Corner balance:

818.....810
782.....747

Cross weight 50.4%

Total weight 3157 including half tank of gas and 215 for driver (2942 without driver)

Brakes:

Front:

996 GT3 4-Piston calipers on 330 Cayenne rotors
Pagid Orange pads
944 Turbo Cup cooling ducts and 968 air spats

Rear:

Stock 944 Turbo calipers and rotors
Pagid Black pads

Safety/Interior:

Heigo bolt-in rollbar
Cobra Evolution GT halo seat
Scroth harnesses
Momo Mod 07 wheel on NRG quick release

Transmission:

Stock 944 Turbo with added Quaife TBD

Steering:

Factory manual steering rack

Wheels:

993 narrow body fitment Hollow Spokes - 8" front 10" rear (no spacers)

I found an engine locally that had been used in a hobby vehicle and then removed.  It was a 2008 build by Turn Key Engine Supply, a 5.3 litre aluminum block with an LS1 intake and their standalone harness (5-wire hookup) and MEFI-5a ECM.  So me and my 6.0 LQ powered 2500HD went to get it.  I gave the engine a good cleaning and wipe down, pulled the pan and valve covers to take a quick look, all seemed OK.  The headers have been sold and the LS3 style (I think) water pump will also be sold.  I pulled the crank pulley to replace the seal, I'll do the rear main seal as well and likely use a fresh oil pan gasket.

I placed an order with Kent at TPC for all the major pieces to make my life easier when it comes to the swap, two nice pieces of the puzzle have arrived...

Nice. Is there any more info on that radiator & fan set-up? I didn't see anything on the TPC website.

Thanks,
Matt

Not much in the way of more info sorry. Kent had it listed in the email he sent me with parts options. It comes with a modified lower bracket (which I haven't received yet so no pictures) to mount it. Fans and shroud shipped with the rad. My engine isn't big power, but being a track car I'd like some extra cooling capacity.

I talked to Kent about getting the radiator on his website. He's working on updating everything.

The price of the radiator kit is $749.

If you are running a stock LS engine, then the factory turbo radiator is plenty adequate to cool your engine. If you are building a higher horsepower engine, then you should consider the upgraded radiator that TPC sells.

Progress!  Engine is pretty much ready to be pulled. Bellhousing, clutch and flywheel are off the back, torque tube pulled back as far as it will go. Job for last night was to pull the engine wiring harness, came out clean with no wires cut.

I would be interested in buying your 944 engine and wire harness if you are selling it.

Thanks for the offer. I'm a long way from you, I'm in northern Canada. But when I'm ready to sell I'll let you know.

Edmonton area for me. Not northern by Canadian standards, but definitely northern when looking from Texas Wink

Coolant temp sensor arrived that fits the existing threaded hole on an LS head and works with the stock 944 gauge.

This little puzzle piece also arrived, M16 Male Metric Straight Thread x M18 Female Metric Straight Thread Adapter.  According some info posted on the board, this will let me run the stock 944 oil pressure guage off the opening behind the LS intake on the top rear part of the block.

Installed the swap oil pan and pickup last night.  

Shot of the inside of the swap pan, each corner of the sump has a trap door:

Put the LS on some storage legs so I can work on the back of the engine. Pulled the old rear main seal and installed a new one, used a couple "special tools" for the job. Next job will be installing the adapter and pilot bearing that fit in the back of the crank.

Installed the pilot bearing adapter and pilot bearing this evening. Used a little Loctite 609 to hold things in place.

Looks like it's going to be a killer build! You may want to check the depth on that pilot bearing though. First time I installed my engine I didn't have that seated properly and I beleive it was throwing off my clutch measurements. Mine looked very similar to yours currently the first time, and the second time it was much closer to flush.

Maybe someone wiser than me czn chime in with exact measurements? I just didn't want to not say anything and have you up the same creek I was!

Thanks JP, appreciate it!  That's exactly why build threads are so useful, I appreciate the extra eyes checking the work, you're all way ahead of me in knowledge.

Do you mean the pilot bearing doesn't look deep enough in the adapter <or> the adapter doesn't look deep enough into the crank?

I've added some pictures that hopefully someone can check.  

This is measuring how much the adapter sticks out from the crank:

[You must be registered and logged in to see this image.]

That measurement is just under 11mm:

[You must be registered and logged in to see this image.]

The next two shots show a straight edge against the pilot bearing in the adapter.  It may be more flush that it looked in the picture above.

Hey, no problem. I've used this resource a lot, so I try to pay it forward when I can! Also sorry for the late reply, work had me out of town.

I'm referring to the depth of the adapter into the crank. But I just checked a photo I had of when I did mine right the second time and yours looks almost identical. The first iteration of my car, the adapter was about 13-14mm out of the crank, and the pilot bearing wasn't completely seated into the adapter either (dumb I know).

Anyway, looks like you're good to go! Sorry to hold you up, but in my mind the adapter was seated further into the crank than in reality. Attached is my pic for reference.

Thanks for the confirmation, really appreciate it. That first picture I posted had weird lighting and a bad angle, it definitely made it appear that things were sticking out further than they were. Love the value of this board, wouldn't think of taking this project on without the knowledge here.

Made some aluminum brackets and spacers to place the oil cooler. This is the same one I ran on track with the stock engine, it's from an RX-7, fairly big dual pass and has a built in thermostat.

I needed to flip the mounting location so the connections were on the other side to match up with the LS.
