:h elpme:I am researching and wanting to know if any of you have built a 4b11t. I have a friend that has a whole engine that I am getting his engine from and it has a little bit of marks in the cylinder from a piston ring scratching it. So my questions are as follows.
As I understand that the OEM bore and stroke is 86mm by 86 mm, what is the biggest bore you can give these engines?
If I plan on just going to 88mm by 88mm, what would be my liter size?
What do you think is the best rods to use in a 1000hp build?
If I plan on building the bottom in so much what upgrades would I need on the top in?
I have a lot of questions but let see what answers I get back on this first.

My block had minor scratches and 0.020 over bore cleaned it up nicely. Just get a 86.5mm pistons or 87mm and give it to the engine builder so they can bore in accordance to the piston they have. I did 86.5mm manely pistons and, manely rods and UCL rod bearings. Car has done 1000 hard miles now and running great so far.

You are correct...
I would be happy with 500+, I just want to have the insurance of a very strong engine. I am on a budget so it will not be built in a month but I just want to do a lot of research to make sure I know what I talking about.

How much did it cost you altogether?

Pistons, rods and rod bearings, gaskets kit Parts were around 3k including accessories such as the 3 gauge pod, 2 AEM gauges and Snow performance stage 2 meth kit. Labor and machining was around 2k. Double checking the tune and adding another map for Meth as well as dyno time another 1500 including Cobb and VP M1 5 gallons.
So total was around $6500, but without all the accessories you can do it for $4600.
