I wasn't really planning on replacing the headers, but since I'm taking it all apart anyways, it sounds like it would probably be a good idea to add it to the list.

Do any of you recommend sending your intake manifolds or the hot side of the turbos to Extrude Hone to have them polished? Then possibly to Swain for the ceramic coating? I've heard that the ceramic coating helps keep the heat down....can also be done on the exhaust manifolds and increases the flow efficiency. I saw the video clip from Extrude Hone and it looks like a great process that may have merit.

I would be willing to rent your LM-1 unit to establish baseline A/F numbers on my stock 930. I am in Atlanta.

Bill, as I said earlier the K27HFS will produce less heat at the same boost pressure than the stock K26. If you are not on a budget then yes, get a B&B IC as well.
I really need to get a LM-1 and an adjustable WUR as I also have a modified fuel head from IA. More £££/$$$...

Yeah, I really don't have a budget. I know that's bad, but when I come up with an extra grand or so then I start looking around for a part. I'm not planning on installing anything until I have all the parts collected. Cause I don't want to take everything apart a bunch of times.
Too bad I don't have more set aside cause there is a B&B intercooler in the classifieds section, but it's too much considering I just picked up a new K27hf. Back to intercoolers, I kinda got the impression from threads, used prices for OEM intercoolers, etc, that they were about useless. But you are saying that the are efficient enough to handle all the mods I've been talking about? So what would be the point of upgrading to a larger intercooler? Maybe I can skip it all together like you say.....

Intercoolers are free horsepower. They also allow you to run higher C/R or boost by cooling down the intake charge while easing the threat of detonation or engine knock.
The stock 930 intercooler (USA '78/9) will hold back a modded engine and not allow all the horses to run free. In my opinion a good aftermarket intercooler is the 2nd most important item to upgrade on a stock USA '78/9 930, the 1st item being the heat exchangers. If you are going to mod your car in stages here is how I would do it: #1 - Headers or Euro Heat Exchangers #2 - Aftermarket Intercooler #3 - Turbo #4 - Cams #5 - Higher Boost Spring (up to 1.0bar) #6 - Go into the heads/engine and start over at #1

Intercooler improvements will never gain HP - they prevent the loss of HP.
A good rule to live by, FWTW.

Isn't that what I just said? "The stock 930 intercooler (USA '78/9) will hold back a modded engine and not allow all the horses to run free."

I didn't plan on #4 or #6 as of now, and 'm going to run a .8 spring instead of a 1bar. Has anyone heard anything about these headers? Ebay Item #:160038627855

For short bursts of speed on the street, you might not be nearly as concerned with buying a larger IC than if you had, say, a local autobahn or track days in mind.
For your use, the turbo + headers and a good AFR may be enough. And a pull fan under the stock IC is a good idea. You live in Michigan.....get headers with heat
