Will I need a machinist for these H-Beams
 
So what began as a simple DIY build has turned into some real fun for me.

I have a garrett T28 off a nissan Rice-14 in the area, still figuring out what to do with manifold/DP/intercooler.

So I was aiming at new rods for 200hp just for shits and giggles and so I can have an excuse to pull off the head to see the condition of the cylinder walls for any scoring I could hone out.

I've been reading on the Belfab/ETD rods and although they are great for the price, will I actually need to find a machinist in the area to hone them down to spec? It isnt the quality of the product im questioning, but the consistency.

I know from many a honda engine that Carillo rods will fall right into place, but they are so damn expensive.

So bottom line. What are the chances that I can just seat the ETD/Belfab rods perfectly fine and not have any problems?

FYI, most aftermarket rods are made to be too small so that they can be custom fitted/machined to the components that are being used to put the engine together. So in short, yes, they will probably require machining.

My Eagle H-beams needed to be machined.

Even the mortgage-priced carillos? I thought that was the point of spending that much? Although to be honest, It probably is fair because the clearances on a 93k motor are going to be much lower thant he bearings associated with these new rods spec'd to stock size

Do the ETD/Belfabs have the notch to squirt oil to the wrist pins? That must look badass in action. My friend with a Jetta build has rods with those and I got a bit jealous.

Who here has used them without a bit of maching and found success? I think its like 200 bucks in this area to have rods worked over
