Engine Build Opinions Wanted
So i'm going to pick up a block here about as soon as I find one locally or reasonably and work on acquiring loot for it over the next several months, Maybe drop it in the hole this winter while i'm bored, I plan on painting the car while it's out anyway.
Goal is pretty simple and straight forward, 250hp, rock solid reliability.
So say you had a 2k budget, and a 3k budget, What would you do for each?
3k is really as much as I can conveniently budget for this without getting too much more **** from the s/o about the car. I would rather keep it closer to 2k, As I have 2k set aside for paint supplies, new seals etc.
---------------------------------------------------------
"Why are you looking at that dumb car like that?"
"Thinking about his new engine this winter, needs more zoom-zoom you know?"
"For ****'s sake blah blah blah money blah blah that ******* car blah blah"
"Would a trip to the Bahama's like maybe shut you the **** up so I can finish thinking?"
".....Are you ******* serious?"
" Yes I'm ******* serious, when's the last time I made a joke about money?"
"That would be sweet!"
"Gee, wouldn't it? Now how about pissing off for a bit,eh?"
...and then she pats the car on the way by like 'good boy'
--------------------------------------------------------
I'm secretly planning on scrapping the greddy setup after the learning curve and building something better and spring that on her as were about to board the flight. She'll be too excited to say anything but 'whatever fine'.
So 2k budget 3k budget how would you spend it???

There are better turbo setups to be had, for sure, but maybe at first keep the Greddy, make 250whp on it, then change to something bigger/better. I'm curious to see how much potential can be unlocked just by doing some headwork and maybe swapping cams.
Also, while the engine's out and the bay's being painted, have the brake booster and some of the other little hardware (like the brake booster's hardline) sprayed. No one hardly ever does it outside of hotrods and VWs but I think it's a nice touch.

What would you recommend be done as far as the head? not much on oem 'type' stuff. I'd rather spend a bit more and get some quality 'type' stuff instead. Not really sure what the machine shop will run yet, I've always built rotaries. When I did machine work I just got out the air grinder and started porting.
---------------
Depends on which route I go with the bay, Still undecided. There's something to be said for the simplicity of a flat/matte black too. I know i'm going to strip off everything that will unbolt. Car will be better than new when done.

Wait...you have the 1.6, are you going to be building a 1.8.
As far as head goes, depends on how much you want to spend, I would at least do some unshrouding and blending, even if you do it yourself. Just get rid of all the casting marks, smooth things out, enlarge the runners slightly, match the IM to the head, maybe a valve job, a better valve-train, cams, etc. if you feel like dropping the money, probably not worth it on the greddy...maybe stick to the first few things I mention until you are ready for more powahs!!!

Well, it is, but that's where you get your power from, the block you build to be able to handle it. Figure out how much you want to spend and stick to it. You can do some of the headwork yourself man, just get you some good rotary tools and take it easy.
I wouldn't spend much on a 1.6 rebuild though, I'd rather source a 1.8 block, build it and strap a 99/00 head to it...300rrwhp.

I didn't even bother with a valve-job, however it was lapped like crazy and the head was milled at least
find my post "headwork ftw" or something to that matter, and it has a lots of info and before/after comparison logs.

When I get around to building my motor I will be using these.

I'm also considering getting the Pro-Gram forged billet steel main caps w/ the Main Bearing Support Plate. But I'm going for high rev and bulletproof.

For the OP, if 250whp is what you are after then you can reach that on a stock motor reliably IMO. You just need to focus your money on things like cooling, and tuning.
