Hi I'm 17 and looking to swap the inline 4 cylinder engine to a v8 chevy smallblock in my s2000, I would just like to know the complications I would go through or if it would even work, any feedback would be great.
Do you
have the same problem?

I hope you're joking. There isn't room for a larger engine. You'll have to use the transmission, flex plate, starter, drive shaft, Engine Computer, wiring harness, exhaust system, gas tank, fuel pump, emissions vapor recovery system, and fresh air intake system that are matched to the new engine. The instrument cluster won't communicate with the Engine Computer so none of the gauges or warning lights will work. The old transmission won't bolt to the new engine, and you'll have to figure out how to make some kind of engine mounts. The power steering pump and hoses are different so you'll need the pump that fits on the engine, then you'll need the hoses that fit the pump, but they won't reach or bolt to the steering gear.

Before you even look at these things, a GM small block V-8 weighs over 100 pounds more than the same size Chrysler V-8, and the Chrysler engines weight at least double of the engine you're removing. The front of the car will be flat on the ground and dragging. Your wimpy coil springs will have to be replaced with something that can hold up that weight, and you won't find such a spring to fit on a strut. Have you figured out how a rear-wheel-drive engine and transmission is going to turn front half shafts?

The radiator will have to be tripled in size and capacity. That means doing away with the head lights. You'll have to shoe-horn in a radiator fan, so the grille will have to go. Your Air Bag Computer won't communicate with the GM Engine Computer.

Even when a serious and possible modification is considered, in particular, altering ride height, you have to understand the front-to-rear brake balance has been very carefully designed for the height, weight distribution, weight transfer, and options list for the specific vehicle. Lawyers and insurance investigators love to find these kinds of modifications on the other guy's cars. They will convince a jury that you were partly at fault for the crash when their client ran the red light because you were less able to avoid it, and they will be right.

If you haven't figured it out by now, you can dream of installing a Chrysler 340 muscle car engine, or a Chevy 350, but leave it at that. If you want a fun engine, buy it in the car it came in. Anything you can dream up, someone else who has experience in engineering, welding, and fabricating will have already done it if it is possible and practical. There's lots of hot rods out there with 340s and 350s, but no Hondas.
