Lower compression allows more boost before detonation and less severe detonation when it does happen.For more power and better drivability, obviously.
This whole turbo = low compression line is BS.
My 93 Ranger had 9.4:1 compression. It was stock. I ran 18 psi on it for a long time.
On Merkur XR4tis one of the BEST mods is to raise the compression.
I was assuming that this guy has an older non dual plug head 2.3 engine. That would be 9:1. With a dual plug head and those later hyper pistons it would be 9.4:1. Any stock 2.3 turbo engine would only have 8:1.
"The one thing the Merkur XR4ti needs is more compression", Jack Roush.
But the number one reason to want higher compression is that I've done it and it works, and it costs less. Listen to those who have done things successfully. Not those who parrot what other talking heads on the internet say.
congratsYou do not need forged pistons. Depending on the year of your N/A engine you may not need to change them. I know for a fact, from my own experience, that 93 ranger hypereutectic pistons will stand up to plenty of boost. These would be a higher compression which is what you want anyway.
You should tell us what year engine you are working with.
You mean intercooler, heads are the the sameBTW, the "best mod" on an XR4TI engine is not to raise the compression, it is to swap on the head from an intercooled Thunderbird turbocoupe
