What is the highest millage you have seen on a built block. Either yours or someone you know that has one built and you know the specifics on the built and how much abuse it has taken. I am looking at getting mine built at inline pro and wondering how long it will last with 10-15psi using a KINGS V2 manifold, S262 turbo running flex driven on the street with no track use.

 

Too many variables

 

This... It is such a vague question there is no correct answer. A poor maintaince beat motor with 20,000 miles could blow and have issues before a motor with 150,000 miles that was properly maintained. Personally speaking I dont mess with anything over 90-100k. Unless it has had ALOT of major work done like the water pump, oil pump, tct, and those major items.

 

Well as far as build for myself, I am looking at the following things.

Inline Pro Signature Block
Sleeved block
Aftermarket pistons at stock compression
Inline Pro Rods
ACL bearings
New water pump
New Oil pump
Inline Pro TCT
ARP Head Studs

Head will just be Valve springs and retainers upgrade

 

I've been in the car scene for a long time. Like most of us on this board im sure the s2000 isn't the first car you had that you modified. With that being said my personal opinion is that a built block or motor is not going to last daily driven. I have been down this road before and I have had better luck with a stock motor with low boost than a built motor with low boost. The benefit of a built motor is that it can handle more boost than its stock counter part before it blows up. Example, the stock motor wont handle 50 psi for even one pass but a built motor will stay together a lot longer. A well taken care of stock motor can handle 14psi for 60k or more but from my experience I cant even get 20k out of a built motor. I chalk this up to built motors having a loser tolerance than oem and when you sleeve the block it cant cool the motor as effective as the original sleeves can. Like I said this is my personal experience and there are to many factors to get the correct answer your looking for. Hope this helps
