Affordable High Performance Sedan

I was in the mood to create a sedan with V8 engine. The car is intended to be a somewhat affordable high performance sedan. I created it in less than 30 minutes. What do you think? Any suggestions to improve the car? :slight_smile:

The engine is a 5.7L turbocharged OHV V8 using Direct Injection.





Here’s the engine. I hit the 3 file attachment limit in my previous post.

Is a twin turbo affordable? I personally would remove the turbos and, expand the engine or move the camshafts to the heads fitting a long stroke crankshaft will boost power, efficiency, and will improve RON rating slightly as well.

Manche raises a good point there, I believe. Your engine not the best ratio or price/performance and you could maybe play around with the tail of the car a bit more… I am sure you can come up with an exciting back end!


Good point. I tried recreating the NA version of it. This time with with OHC.

Definitely better! Now look at the service costs per year…would you want to pay that? :slight_smile:

Thanks :slight_smile: Any idea on reducing service cost except moving to standard intake? It still gives me $2000ish service cost per year.

I think that’s fine, a performance sedan with a big V8 is never gonna be really cheap on service costs :wink:

check that out… I accidentally sumbled upon a way to make good Ohv engines… who says that undersquare blocks are obsolete?
