Interesting FAQ i found

How much will the car weigh?
We have not weighed the converted S13 in stock form yet. However, the specs should be very close to the S14 information listed below.

The aluminum GM LS1 and LS6 engines are extremely light power plants. With the complete removal of the KA engine and transmission, the project car's final weight is less than the total gross vehicle weight of a stock Nissan 240SX. The LS1 T56 combo is 128 pounds lighter than the KA four cylinder it replaces.

The final weight of the car is listed below. The car weighed 2,742lbs with a full interior and atleast a 1/4 tank of gas. This results in a F/R ratio of 56%/44%.
LF: 737
RF: 815
Total Front: 1,552 lbs
LR: 620
RR: 570
Total Rear: 1,190 lbs


How will it handle?

The converted car should handle better than the stock car due to the weight reduction. Our customers should expect their vehicles to handle just atleast as well as it did prior to the install.
How fast is the car?

Depending on the level of engine modification, our customers should expect even a stock LS1 conversion to perform better than a C5 Corvette Z06. All of this for less than 1/4 the cost. Most of our stock LS1 240s will run between an 11.9-12.5 second 1/4 mile pass. The range is based on track conditions and driver ability.
Our shop car has gone through a wide range of performance parts. Be sure to check out our media section for videos. We've built everything from 11 second daily drivers to our soon to hit the track 7 second RX7 monster. Stay tuned for progress on our shop S14 240.
How difficult is the conversion?

We have gone through great measures to build custom pieces for the 240SX. Our engine subsystems (cooling, fuel, hydraulics, etc) are built specificly for your model year, and the installation is very intuitive. However, we will provide instructions for parts that need explanation, and we are also available for phone and email technical support.
How much will it cost Hinson Super Cars to complete the conversion for me?

The cost for turn key cars is discussed here. Please review the page for your turn-key construction questions.
Where can I find an engine and transmission?

New and used engines and transmissions can be bought through HinsonSuperCars.com. Alternative sources are the classifieds section of LS1.com, LS1tech.com, and EBay.
Will I still be able to have air conditioning?

A/C is available on turnkey cars as an option. We do not offer mail order A/C services because the high possibility of damage to the lines during shipping. We feel it is in the customers best interest to find a local A/C shop and have them mate your RX7 and GM A/C lines. With this approach, you will have a warranty under one roof.
Does the car still have power steering?

Yes, all H7 cars will use the stock 240 power steering rack. However, many of our customers choose to remove power steering for a better feel of the road.
Will my stock 240 cooling system work?

No, you will need to upgrade to a larger radiator to ensure great performance for years to come. We offer a ready to install cooling systems complete custom built radiator, new single HD Flex-a-lite fan, all hoses, clamps, condensor mounts, radiator shroud, and more. These cooling systems are standard in our turn-key builds. More information available here.
Will the real end handle the extra power of the LS1?

The stock VLSD 240SX rear end is a solid piece. The rear end is strong enough to handle the duties of daily driving, road racing, autoXs, and drag racing. However, a very high horsepower LS1 can break rear parts when launching on slicks, but this is a problem all drag racers face in any type of car. If you plan on running 9 or 10sec 1/4 mile passes, there are aftermarket setups available for installation to strengthen the rear. Check here for more information.
The KAAZ and chromoly axles carried us in to the low nine second range in the RX7. If you're interested in going faster, we can build your car up to NHRA 25.5 specifications or install a custom built solid axle rear end. Contact us for pricing.
