Well so let's make a plan. Or try to. If I was going to just build something, what would be smart for me. I'd like to try to use as much of my existing stuff as possible, but not so much I'm gambling terribly.
Since I am going to have to spend money where I didn't really intend to, it looks like I will be draw through for a while. Or I can blow through one of my Holley's.
Here is what I have :
Stock 1600 that as far as I know has never been apart.
HD single valve springs. Probably less than 10 miles on them
Chromoly pushrods. Same 10 miles
TD04-13T Subie turbo
350cfm or 500 cfm 2 barrels or 390 cfm 4 barrel
1 3/8" tube for header (not built yet)
So what are your thoughts. I'm not looking for a drag car. Just as much grunt as I can get for my $$ spent.
Of course I will need a better trans sooner or later, but I would have anyway before I found these problems. So let's assume it will be next on the list.
I don't really have a budget in mind but I'm a tightwad!
Also most of my driving is going to be around town. Most roads here are 50mph. Some places tons of stoplights and some more open. No way I will ever take it on the highway/interstate here. Just too dangerous!
Bang for the buck?Leave the crank and cam alone and maybe step up to a machine in 88mm p&c with some nice heads? Change the cam to get more from the heads? Put a CW crank in, or maybe a small stroker? What are your thoughts?
I will probably put this on the other site just to get some other opinions too.

I would get some opinions on replacement heads and move forward on your carbureted turbo. Have you changed annular boosters on any of these carbs to get it to meter better? I would roll the dice with a pair of heads like these and check them over before installing. https://www.kustom1warehouse.net/Dual_p ... 01355c.htm

I haven't changed to annular boosters on them yet.
And those heads are a good option, my only hangup is they are $195 cheaper than the coveted Panchitos. That doesn't seem like much if the CB's are good as everyone says. That is both opened up to accept the machine in 88's. I don't see much reason not to get 88's if I am buying new heads anyway. The extra cost to have them opened up for that is minimal. And HD single springs in both. That is of course unless the CB heads are just too much for this. Their website says they will work with a medium 1600. I would think a turboed 1600 would be considered medium?

If you open up the case you are going to be prone to do work or replace marginal things which will expand your project and may not other wise be needed until down the road.The info I have gotten on CBs is they have bad valve seats. I believe the bigger heads have bigger chambers which is going to eliminate the squish effect which will make the combustion process for a carb engine even worse.
What are your power ,MPG and drivability goals? A 1600 is going to be a gas sipper at idle and around the town cruiser. I'm pretty sure that 1600 mahle kits are much lower priced then their big bore offerings.

I don't care about mpg at all. Of course the more power the better. And I don't want to have to wring it out to drive it.
And yeah it looks like the 85.5 bore is about $100 cheaper

It sounds like you should stay on coarse with the 1600 at this point. Maybe you could try to find used heads locally and if that does not seem reasonable get some decent stock or just a step over stock new heads.

I pulled the short block apart today and threw it in the parts washer. I was amazed how light the block is on these once you get the crank, cam, and fly wheel off.

Do you guys think it would be foolish for me to bolt my case back together, throw the cylinders and heads back on and put it back in the car to start building my header. I figured right now empty it would be light enough it would be easy to get in and out while its empty. I haven't ordered anything yet so I could be moving forward with something. Keep in mind I will be getting new heads and p&c. I don't "think" they would really be different, but you never know I guess. Thinking it would be close enough for mocking it up.

Not foolish at all. I built most of my intake the same way. Cheap jig.

The ease of putting it in and pulling it out is what is really appealing!
The engine builder at work is going to check it out and measure everything tomorrow. So I should be able to get to tacking it up this week. And I can start ordering my parts is the case checks out.

Also, is there any good reason I shouldn't build it into a 1915? The machine work on the case will cost me nothing. And I have to buy heads and p&c anyway. I see tons of guys building them NA with stock cranks. Doesn't seem like there would really be any extra cost involved. Just different selection of cam, 40x35 head should still work fine, turbo should still be fine. Header tube I bought might be iffy though. 1 3/8" has to be borderline, but I'm not planning on spinning it much over 5000 rpm so it may work.

Unless you are trying to build a motor to fit into some kind of envelope, like a mouse motor, then build as big as you can afford. The 1915 has the benefit of allowing you to run big heads if you want. Pistons and cylinders are really close in price either way. It will be a little bigger and could make a little more power.
