I am a 13 year 944 owner and an engineer that grossly over maintains my cars. I absolutely love this car but my attention has been diverted to an air cooled 911 project.

I bought this car in January ‘08 from a friend in the Metro NY PCA and have put about 30k miles on it in that time. The last 3 owners before me, through 1998 or so were all PCA members whom spared no expense. Includes a 3" thick folder with logs and receipts of everything that has been done to this car since 1994. I have hundreds of picture documenting every aspect of this car over the 8 years I have owned it.

CarFax and New York State title are both clear. No accidents or odometer issues. I am the 5th owner I think; and I know the last 3. Again, this car comes with a New York State title (i moved last year).

All body panels are original and still have the VIN tag sticker. The front end (fenders, hood, bumper) was resprayed at some point. Everything else is original as far as I can tell. No rust or corrosion anywhere. The paint is decent, but not perfect considering the age and mileage. Not a concourse car, but very presentable. The interior is in great condition, the dashboard has 1 crack with a few small hairline ones developing around the vent holes.

All of the bugs have been worked out since completing the engine swap. Along with the street miles it has completed a number of auto-x’s and DE’s since.

The car has good street manors but holds its composure on the track. It is fast and smooth… the LS1 power band is nothing short of awesome in this car. At just over 2500 rpm it is already making 210ft-lbs and at 3k rpm will maintain no less than 310ft-lbs all the way to redline which is set at 6500rpm.

Details of the LS1 engine swap

This entire build was documented here;
http://944hybrids.forumotion.com/t16...ls1-conversion

The donor LS1 was from a rear ended ’04 GTO with 58k miles, it was purchased from a dismantler in PA (I have all paperwork for it including the original VIN from the donor car). The LS1 from the ’04 GTO is the best derivative having the LS6 block. It also comes with the LS6 intake manifold and PCV setup. The engine was taken down short of the pistons and crank; So the rings and rod bearings are original and untouched. Cylinder walls were perfect and bottom end was very clean when I took the pan off.

Every gasket is brand new and while it was apart, I made a few upgrades which have been detailed below. Mostly everything done was to improve long term reliability.

The car was dyno tuned and made 382whp and 348ft-lbs on a Mustang dyno with 93oct. In Jan. 2016 it was retuned for 91oct. 2-degrees timing was pulled to increase the safety margin with the gas available in CA. With this tune it put down 363whp / 349ft-lbs. It’s tuned very well and rides great even at part throttle on the street. No bucking or strange part throttle behavior… it is smooth! The cylinder heads are the stock 241 castings with a basic rebuild. More power is still on the table with ported heads, intake / throttle body and a bigger cam. I opted not to upgrade further because I do believe you can have too much power. The cam installed right now was spec’ed by EPS (Engine Power Systems) for the most usable powerband (and giving you the lopey idle everyone hates to admit they like!).

All engine swap specific parts are from Texas Performance Concepts (TPC); this includes engine mounts / uprights, bell housing adapter, oil pan…etc.

The engine utilizes an f-body accessory drive. One really nice thing about this swap is none of these parts are really one off or unobtanium. Everything is off the shelf stuff.

I am very particular and went through great efforts to make this a clean swap and keep the engine bay tidy. More cleanup of the wiring can be done if your super **** like me; but the car looks great right now as is.

Heat works as normal and has a heater control valve installed. No a/c on this build, but if you were up to the task, it could be reinstalled as everything under the dash is still present.

Fuel Support
All rubber fuel lines from fuel rail to fuel tank have been replaced. Fuel filter as well as fuel pump suction screen in the tank have been replaced.

Fuel system is setup like the original 944 with a return type system.

Aeromotive billet fuel rails
FAST 36# injectors

All battery cables are new

Exhaust
The headers are long tubes from Texas Performance Concepts and were coated by SwainTech. The headers merge into a Y-pipe which connects to a 4” single exhaust (yes you read that right, 4” exhaust) with a Magnaflow muffler.

The car has a very distinctive lopey idle and screams at full throttle.

Cooling
Engine runs very cool at speed and has no issue maintaining temperature at idle.

Radiator is from Renegade Hybrids for LS swapped cars. This radiator is made by Ron Davis and is excellent quality.

Hoses are off the shelf parts available at any autopart store than are cut to fit. I have all the part #’s to make spares.

Spal 16” straight blade puller fan – the most powerful you can fit without modifying the radiator mounting.

Brand new water pump and thermostat

Clutch
The clutch is a Spec Stage 2 setup. Very good street manors and will support well over 600ft-lbs. Pedal is firm but manageable even in traffic. The C5 2pc bell housing is mated to the Porsche torque tube with a TPC billet bell housing adapter.

Spec billet flywheel (great engine response)
C5 throwout bearing
McLeod remote bleeder (can bleed from under the hood, no need to crawl under the car!)

Steering
Power steering is retained with a 944 steering rack. The rack is powered by an F-Body power steering pump which was re-valved by Turn1 to work with the Porsche rack. All high pressure lines on the rack were replaced with stainless braided lines to improve routing around the oil pan. The steering shaft was lengthened to accommodate the slight cross member drop. A power steering cooler is installed next to the radiator.

Brakes
Power assist brakes were retained by retrofitting a 2000 Ford Mustang hydro boost unit. This is a hydraulic brake booster than runs off the power steering pump. The Ford hydro boost unit is mounted to the firewall using a custom adapter plate. The master cylinder is also from the Ford Mustang. All parts are brand new as well; the hydro boost unit is new from Ford Motorcraft along with the master cylinder (not rebuilt parts).

A Tilton bias valve is mounted next to the shifter column to control rear brake bias which shifts rearward with the Ford master cylinder.

The car has excellent stopping power and very low effort is required on the pedal thanks to the power assist.

Body
The only modifications needed body wise was removing the hood latch and headlight bar. The upper radiator support was also removed to accommodate the larger core. Aerocatch locking hood latches were installed. Also a 914 headlight motor was installed on the driver’s side to retain the pop up headlight functionality.
