Several weeks ago I brought the engine to a friend to give me some much needed assistance finishing everything up. I might have been able to bolt it together and call it good on my own, but I had way too many questions to feel comfortable doing it on my own.
One of those things that concerned me was some wear on the cylinder walls. It wasn't as bad as I thought it was, but finding stuff like this is one of the downsides of buying a used engine. Most likely this was caused from not letting the motor warm up before driving it.
Anyways, here's where I'm at now. It should have been finished yesterday, but I'm at a crossroad. To use or not to use....

Made some more progress today. Got a fitting welded on the oil pan and finished inspecting everything for the bottom end. Oil pump is installed and the pan is back on, should finish up the rest tomorrow.

ok dude good answer...
big turbo doesn't mean jack until you get over 14 or 15 lbs of boost. it doesn't matter what kind of turbo you're running, it depends of the manifold boost pressure.
all i know is, he's starting with around 120-130 whp stock, and at 10 lbs of boost, no matter what injector size, AFR, or turbo size, it should only put down around 200-220 whp.
of the knowledge about boosting 1.8's that i've gained, you would need a built bottom end (idk about post '98, mine's a 97, but i think they're the same bottom end. if not, someone tell me the difference) and over 15 lbs of boost.
the only difference i could see with his car would be having a different tranny, or an lsd. but, idk what kind of advantage that gives you on the dyno.
someone please enlighten me.

Looks great. Every time I look at one of you guys build threads it reminds me of how much I can't wait to find another engine and start a real build, not just a stock rebuild.
Just a slight thread jack. I can't say I recall seeing anyone on here who has built a bottom end lately use aftermarket main caps. I suppose that is because ARP studs are all one needs for a "bulletproof" bottom end? Though my bottom end is stock, I still kind of wish I had use ARP main studs. Probably not needed though, as Im sure the rods will give long before I have any worries with caps or bolts.

i'm not threadjacking you *******...just want a brief explanation on how he thinks his car made the power it did.
and jayl, i would start a new one, but i'm too new to do so i think.
so excuse me and never mind. i'll just keep reading you guy's stuff wondering whether it's bs or not.
