Pulled the engine, helicoiled another engine case hole for the head bolt (that's 2 of 10 now), and got the head back on. Everything is torqued to 35ft-lbs as per spec. Finally.
The biggest snag is finally taken care of. Now I've just got the cams to dial in (a pain in the ass), some assembly, some parts to bolt on (sprockets, et cetera), clutch, and some creative stuff like my fuel system.
Couple days and it could be all together. Then a tune, and it'll be good to go.

As for the DSM intercooler being junk I disagree. I ran my 91 Talon to a 12.1 @ 110 on a stock side mount at 26 psi. Much faster than anyone expected. And a friend went 12.4 at 108 with a stocker and another 12.6. Mind you all was with the race gas band-aid. But I did run a constant 19 psi on pump all day on the street. Just no 4th or 5th gear pulls or that ****er would heatsoak bad. But I'm guessing your running a smaller turbo at less boost so you should be fine.

Smaller turbo, less boost, and it's now a front mount getting a ton of air. But it is cut down. I still think it'll work.
Got the engine back in today. Took some pictures too. I'll get those up in a little bit. You can see my Vortex aluminum rear sprocket. It used to be 45 teeth, but is currently now 35. The last time I rode it before handing it over to my fabricator was a trip to the drag strip. That night before leaving my house I noticed I was missing two teeth. Still went anyways though. So in the process of riding to the track, making passes, riding home from the track, and riding up to my fabricator's place, it lost 10 teeth.  I'm going back to the stock steel one anyways. Maybe get something even smaller in the future.
Stock headgasket is about as thick as a dime. Actually, a little less. Like a really high quality piece of art paper. The new gasket as it sits right now, clenched between the head & engine case, is as thick as a half dollar. Well, if you give the half dollar a good whack with a hammer. With the gasket, air:air cooler, and fuel running through an ice tank, I don't think predetonation will be a problem.

Say my stock intercooler face is 8 by 8 inches, my duct is about 6 inches long with an opening of 5 by 5 inches. Also make sure to seal up all the sides so the air has to go through the core and not around it. You can see gains of up to %20 in efficiency with a nice duct.
Why the smaller opening?
I don't have much room (if any) to make any sort of ducting or shrouding for the IC, but one of the projects in the next couple days will be fitting my 9" pusher fan to the front of the 8.something inch tall radiator and shrouding it as best I can.

The best shrouds for any kind of heat exchanger always have a smaller opening than the face of the core. This is due to the fact that if there is no ducting present less than 1/4 of the air molecules that hit the core face will actually go through the core anyway. So basically the opening can be 1/4 the area of the core face and not cause any degredation to the cooling affect of the intercooler (or radiator or whatever). Plus with the opening smaller the air in the shroud gets presurized and really wants to go through the core and not back out the opening. That's why it's so important to have the sides sealed.
A nice simple duct for you would be just to make 2 pieces as long as the cooler and about 2 inches deep, then make the side pieces semi triangular like so that one of the long pieces is angled and makes the opening the same length but only half the width.
I'm not around to look at my bike right this second but is there any room to put the stock fan on the other side (i.e. passanger?) of the radiator? A fan in front would be a PITA to seal up against a curved radiator and be a HUGE restriction at speed maybe to the point of causing you to everheat.

Negative. No room but the front. And the stock fan doesn't like rotating the opposite way (pusher style). I've got aluminum sheetmetal, tin snips, and rivets. I'm good to go for shrouding.

Hi guys, I am new here and have been reading a few posts. You guys seem like a nice bunch unlike alot of other forums. Lemme tell you all alittle about my bike.
1999 900RR
MC-XPRESS KIT
PORT & POLISHED HEAD
WEB CAMS
UNDERCUT TRANS
LOCKUP
3-9 ARM
PM WHEELS
MSBC-1 BOOST CONTROLLER.
Never been on a dyno, so I cant tell you the hp. I had a 4" arm on my bike and a dead shock so needless to say, not good dragrace times either.
laser20psi, I have 120 main jets, stock needles, and I run between 1.5 - 2 psi fuel pressure at idle. Make sure you get a bypass regulator that increases fuel pressure under boost.
66droptop I have a mc-xpress intercooler that fits perfectly in front of the radiator. It would be a pita for you to convert over to one now since you basically would have to fabricate all of your plumbing to get it to work. It measures 8 1/2" X 14 1/2"
I think water injection with a hobbs switch will be the easiest way out. But, if you are not running more than 10 - 12 psi with c16 fuel, you will be ok.

How much boost are you running, and on what octane fuel?
I'll be running my fuel through an ice tank, hoping to gain some of the benefits of water injection without the extra hassle. I wonder if it's going to make much of a difference.

On the street, I usually have my boost controller set at 6 lbs. It is easy to do with the boost controller I have a MSBC-1. It is right under my guages, so I can change the boost on the fly.
On c-16 fuel, I have run up to 11 lbs of boost. I have stock compression, and stock rods and pistons, so I am not pushing it. I was planning to sell the bike and get something bigger, but I will get hosed to much so I am planning to keep it. I am going to install some turbo pistons and some rods in it, so I can really turn it up and not worry. But to date, I have seen to 11lbs with no problems.
Those carbs cannot take much pressure. If you have 3 1/2 lbs or more, you would definitely flood the carbs and fill the engine and exhaust with gas. (don't ask me how I know! )
I can't wait until you guys get your bikes running. Riding a turbo bike is like NOTHING ELSE. I have ridden bikes with 40 - 60 hp of nos, and nothing feels like a bike coming up on BOOST!!!!

I think mine are at about 3psi. My Malpassi fuel pressure regulator is doing a hell of a job. My pump is running like it's on meth. I'm amazed at the amount of fuel pouring out of my return line. It's like turning on the water faucet in the kitchen, just minus the air. The second time I started up the bike, I had a kink in the return line (I've got the feed and return line both running to a plastic gas can propped up next to the bike) and my carbs started pumping fuel out of the bowl vents. I about shat myself, thinking all my fuel problems had returned. Then I saw my line was over reaching a bit and was kinked at the bottom of the regulator. Brought the gas can closer, and my problems went away. Phew!

New guy to motorcycle turboing. I'm kind of a long way off on this, but I'm poking around with the idea. I'm rebuilding my f2/f3 basically from the ground up, and my buddy just gave me a T25 of his SR20. I've been doing some reading on turboin the bike, but my main snag is the fuel system. With FI I understand how to manage it, but with carbs I know nothing. I take it, I need a variable fuel pressure regulator? How will the fuel increase in accordance with the boost?
