Re: Turbo---180 hp vs. 150 hp

You can convert the turbo to a 180 cold side and use a 65-66 carb, it'll be a 180 at that point for all intents and purposes aside from the fact that it will spool a lot better because of the smaller turbine. PM me if you need turbo work done.

Re: Carter YH carburetor

Another broke YH, imagine that. lol

Fix: convert to electric pump and return style regulator, set to 1.5 lbs not higher then slightly lower the float level. I hate the YH, it never ever worked right for me.

Marvel Mystery Oil FTW! Put some in each cylinder and see what happens, that stuff is liquid gold for freeing stuck rings.

Re: Ignition timing range ?

Easiest way to think about it: mechanical advance works with engine speed, and is independent of what the manifold pressure/vacuum is doing. Boost retard/vac advance could care less what engine speed is, it takes it's cues from the manifold signal. They both work together to make sure the engine has...

Re: Turbo

I rebuild turbos for members here, if you're having issues drop me a line. I'm working on another members turbo right now, but it will be done this week.

Re: Ignition timing range ?

What is the timing range for an LM Turbo. I know the advance limit is 24 degrees. Once the turbo kicks in, what is the retard range as the boost increases? Advance limit? Not aware of that term, but the 24* figure you referred to is base timing at idle. Then as Brad stated there is some centrifugal...

Octane boost is the devil, only thing I ever got from that stuff is fouled plugs!

Re: Turbo issues..

The housing in your first picture has either been welded or had a sleeve pressed into it, to correct an oil leakage problem resulting from the turbine oil seal being jammed into the housing and gouging it. You should use a later Rajay 310 series heat shield with it since it has the correct size hole...

I have Megajolt does that count? :p

No knock sensing, but crank trigger and mapped advance helps a whole lot in avoiding knock related problems.

Re: Gasoline Opinions...

which modern day gas would be better for an old turbocharged corvair - the 93 octane + 10% Ethanol gas or the 85 octane alcohol-free gas? Define 'better'? If driving cheaply is your goal, the answer is obvious. If you aim to drive on boost at all, you need as much octane as you can get to avoid det...

Re: Ignition timing question

Probably not. Because these engines run so rich, carbon immediately covers up any aluminum flecks that would have migrated to the plug electrodes. Just listen for signs and be careful.
