This build started with the purchase of a 1991 Nissan 240sx Coupe in early 2014. When I first got the car it had a full Nascar style cage with a completely redone wiring harness(done very nicely with a diagram).
My plans for it were uncertain until I talked to some of my friends. I wanted the build to be unique, but I wanted something reliable, like a tank, and parts that were cheap and you can find them everywhere.
I went with a GM motor. A 3.8L V6 – the 3800 which we got at the junkyard from an 2005 Pontiac Bonneville. The cars they came in were not so great, but the motor themselves were very solid and even came supercharged.
After mocking the engine in the car we saw that we needed to get a different oil pan since the stock brick-style one made the motor sit way too high. I ordered a front sump Holden Commodore oil pan from Australia which helps it all clear the front subframe. Several small modifications will need to be done to accommodate the new changes as well. I also got a T5 world class transmission out of a 2002 Camaro, which bolts right up. Then my husband and I made up engine and transmission mounts to finally get it mounted in the car. The engine mounts were all custom, but we used the stock 240 trans mount with metal spacers to have it mount just right. Later, we ended up buying some rubber bushing washers, so that the vibration of the V6 wouldn’t be so harsh.
At first I had plans for a 3800 Supercharged motor… then a turbo… then just naturally aspirated. But then that changed with a small trip to the junkyard. We found a car with it’s entire front end burnt to a crisp. But a jewel laid on top of it all – a 2007 GTP supercharger. At first, I was unsure about it, but we took it off and it really just needed a little cleaning. I was very excited.
I did need to do some upgrades to the engine itself with ARP head studs and the best intake manifold gasket money can buy plus the gray gasket stuff XD.
Nothing too exciting was done to the interior. Just a stock dash and I did end up doing my own gauge cluster and switch panel. A head unit and sub are also on the list to be added 😉
