I'm wondering at what rpm's a '61 would spool a 20g-yikes? As a daily driver methinks a 16g would be almost the largest one would want; sure you might lose some ultimate speed but on the street what is a second when traction is usually the limiting factor anyway.
I too want a stock appearing(sleeper) exterior so have tossed the stock rad and had a custom(honda sized) three core unit made so the intercooler is beside the rad next to the battery where there is lots of room for it and also having benefit of short piping. Another benefit with this setup is the room to place a cooling fan on the intercooler. One problem with this is airflow as the bumper rebar is HUGE and directly in front, so that is removed and replaced with a much smaller rebar(easy to make).

4g63t is strong. you can detonate all day long and the rod will not break or bend. i was dynoing with 40 knock counts and the motor is still going good.

another advantage is, you can make this water to air intercooler by yourself with the right resources.

For absolute power production I think a liquid-to-air setup is the only way to go -- how else can you get air-charge temps below ambient after compression?

Do remember, however, that heat soaking can become an issue with an air-to-water setup on the street. Although an air-to-air IC can also heatsoak, a hollow-cored IC will cool much faster than a reservior full of water. Think about how long it takes a radiator full of coolant to cool off after sprited driving -- we're talking hours here. You're going to be using a relatively small volume heat exchanger to cool the water in the IC, and it can gradually heat up while driving, decreasing performance as it does.

For drag racing it isn't an issue, but for hot-lapping or auto-x, you really wouldn't want an air-to-water IC. It all depends on your application.

I was thinking of doing air to water and using my old AC coils to cool it off.

Like a moron though, I threw it out when I moved.

Making an 11's daily driver out of the 61 will be nearly impossible and it still be a "daily driver". Traction would be a major issue and you won't full spool till 3rd. I'm getting another 61t to build up as this is also my plan.
I'm planning on using oversized pistons designed for the 63t to help gain a little displacement and aid in spooling a larger turbo. I'm debating on using a 2.0 head and Intake manny since I will have a larger displacement. The short stroke will hold together better than the 63t and turn more RPM's without worry. You can do it, it will just take time and money, not to mention good tuneing. Good luck.

my friend turns his 4g63t to 8500rpm. remember guys, we don't have pushrod motor.

True, the valve train is acutually the limiting factor on both 61 and 63, but the short rod ratio of the 61 will handle higher RPM's over a longer period of time with out worry of the bottom end coming apart. The 6 bolt bottom ends are all pretty much bomb proof.

Mysteryman and Nodents, do you have any pictures of your setups?
