I grafted one onto my 1.6 sohc (mazda) and it makes boost fast at as little as 2500 in second gear. I'm only running it up to 6 pounds, stock internals and all. Yeah, I was surprized to say the least.
Show a pic of the intercooler with a tape measure so I can get some sense of dimensions.
I'm running a "Coolingmist varicool II" right now to control the top end.

Boosted samurai FTMFW! I seen one here mud riding one that was on 35's, 10 PSI w/ WI. Not even four-wheelers could go where he went. He ended up breaking both new front hubs and got stuck. We pulled him out and he ------- drove in 2WD out of this valley that I don't think anything else before him has ever left out of without 4WD or a cable pulling them up. He was in 3rd gear boosting moving forward about 1/2 mph up that hill. I thought he was gonna light the tires on fire. Was the coolest ---- I've ever seen. I've always wanted one to build and boost. They're sick.

sweet are you running a pressurized regulator so fp stays ahead of boost? any 1:1 ratio works and the book torbomania by bob tomilsone written for turbocharging aircoold vw has lots of stuff how to prep a carb for blow throw (tahts where i started boosting before hmt old school air cooled )

I have the regulator, and am working on getting it installed and setup still, worked on it tonight a bunch, got the msd 6btm installed and mostly wired, still need a few bits and pices to finish that part up. Got the fuel lines bent and installed to the rear axle but still need to pull the tank and get a through fitting for the return and get a bigger feed tube in the pickup.

The bike carbs are gravity fed I'm pretty sure, so I need to be spot on with the fuel pressure. So I'm running a 5/16 feed and a 3/8 return line. This will make damn sure that the fuel pressure regulator will be able to control pressure properly. I just don't want to have a issue with too much fuel pressure at low loads. I'm running a inline pump from the ranger as its pretty low flow. I'll let you know how it works but anyone have a pump in mind that you think would work ok?

The manifold ells are the vibrant schedual 10 stainless ones. I have a bunch of the manifold flanges too so if you know anyone who needs/wants one. I have about 40 bucks into them. I also have a bunch of the ko3 turbo flange still if anyone is looking. They are both 3/8 stainless water jetted.
As far as cracking goes I know it will eventually but am hoping to get some miles out of it. I am a servicable welder, I can tig ok and mig allright. I'm no pro, but my stuff usually doesn't randomly explode. Aluminum still kicks my *** every now and then, my consistancy is in need of work, but I'm getting there. The inlet plenum turned out better than it should have concidering my abilty, but I'll take it.

As far as the boost threshold goes, that would be great if it lit early, but my real reason for the turbo in the first place is freeway driving to and from the wheeling areas, i'm tired of hills kicking my ***. This is truly one of those few times were the turbo is being added because of need not just want. Anyway, thanks again for the help and warm fuzzy ----. I got some great action shots from the last wheeling trip I will try and post here in a bit.

I'd be interested in a couple of those k03 flanges. I'd want one of the 3 bolt, going into the turbine, and the 3 bolt flange going out of the turbine (for downpipe). It's a 3 bolt out of your turbine no? I know KKK also has a 4 bolt k03/k04 as well as the 3 bolt. The downpipe I fabbed coming out of my k03 is a 2"od, but it looks like you maybe did a 2.5" hole?

Actually, the outlet on this turbo is a strait 3" opening. Its almost the same a standard 3" 3 bolt header flange. I got my 3 bolt flange from vibrant. It was 18 bucks I think. The turbine inlet flanges turned out pretty nice. Pm me your adress? I will post the actuall part number from vibrant tomorrow. I had to file the holes out about 30 thou. and I think I needed to drill the holes out to 7/16 but it worked perfect. I don't run any gaskets, I just made real sure the flanges and head were flat and clean. No leaks so far. I got a bit more done on the sammy tonight. Still got to drop the tank and do the mods there and mountthe pump, but I am closer.

Here are some pics of the manifold I built to mount the carbs to the head. Its simple but it works.




Like I said, simple.

looks sweet why is that hose there .. circulate water throw the intake manifold .. per heat sorry cant really read right now..

fastspec2

No, not preheat, the water flows throught the manifold before the t-stat houseing. The tubes are because I made the manifold on a peice of ---- ***** drill press that wouldn't drill a stait hole toave it from the nippon trash heep, so I ran the water externaly instead of drilling the passages internally like was my first idea/desighn. Currently I have access to a decent cnc machine and have solved that issue, so I can make new manifolds with the water passages inside instead of the tube arrangement. Either works, and the external tubes looks way more hmt.

Those are mikuni snowmobile carbs man. Webers aren't that good and they take a lot of time and preparation to pressurize and get ready for boost. These mikuni's are far easier to use.

Nice build dude.

Smith-02

don't tell him or me what carbs he doesn't have. i posted webers because at the time of posting i did not see he stated what they were (look like sidedrafts anyways)

now ---- off and post something other than trolling useless information
