I too, am budget minded but only so-so with the wrenches, and not nearly the time (to many expensive hobbies).
I agree that a V8 engine swap would be the easiest way to gain performance.
Simple questions I would like to ask (not pissing on your thread)
1) Will you need a new ECU and if so, would it be compatible with the wiring harness, sensors etc..?
I would need to get the ECU and engine wiring harness with the V8 engine.
2) I assume you have a 6 speed manual transmission and it will mate to the V8?
I have an automatic. The automatic should bolt up but still trying to verify. The automatics should handle the power.
3) Will Limited suspension be able to handle the extra weight and speed?
yes. Only 130 pound difference. I will also be adding my own brake kit to the car which is much better and light than the SRT big brakes.
4) Will the differential handle the extra torque?
yes it will
5) What other mods do you think will be needed to accommodate the exhaust manifolds (or headers) if any. Will you need to modify the frame etc..
Stock exhaust manifold should work or C43 or C55 manifolds will. Keelman headers are also available if all else fails.
6) Do you have a good digital camera for pictures?
No, not yet still having to use the one on my cell until my digital get back from Olympus.
Rentech, AMG and Startech know all the answers to the questions around a V8 Swap and none of them are talking. they would rather sell the conversion for astronomical prices. I have done what appears to be much more complicated swaps in the past. Next time any of you are at a car show look at the brand new Corvette engines and computer controlled transmission in the '30's street rods. It isn't hard to make this work as long as you have the original harness and ECU's to go with the engine.
