Picked up a small 16g, 2g exhaust manifold, 90 turbo ecu, and a small FMIC. So much for waiting.

Made some good progress today. I installed the FMIC, removed the air conditioning, replaced the two broken pieces for the gauge bezel that I have had forever, removed the power steering cooler, modified the core support for the intercooler pipes and removed the stock fans in lieu of two 10" slim fans that are on the way. Those will be set up as pusher fans. I also cut the front bumper and front bumper cover to clear the intercooler.

I also cut the four longer brackets I needed for the rear suspension on the truck.

I have some parts on the way, but it may be late september early october before this is 100% complete as we may be heading to World of Speed in two weeks at the salt flats. I need to make sure I have enough money for the trip and bills.

The intercooler came out just a hair over 1/4" lower on the driver side. I was just going off the bottom of the frame rather than the floor like I should have. But after I cut the bumper cover it warped(was warped) pretty bad. It kind of curls and is higher on the driver side. It looks a little goofy, but the intercooler is pretty close for eyeballing it.

Waiting on parts still. I did receive my knock senssor connector. Mounted my new 10" fans today. They are off and old a/c connector. They switch on with the ignition. Also painted the brackets I welded on last weekend for the intercooler.

The ecu came in yesterday. Still waiting on my manifold. But Jaysmirage gave me a turbo mirage bov, a 1G bov steel flange and a 1g O2 housing today. I also got the oil return fitting for the bottom of the turbo as well as the oil feed fittings for the top of the turbo and oil filter housing. I got all the fittings on the turbo and mounted the O2 housing as well. I cleaned up some old crusty weld for the studs on the O2 housing and rewelded them a little better.

I am suppose to leave for Bonneville next week. I need to make sure I have enough money for the trip, bills for the month and some emergency money. But I think before the end of september if things continue to go well at work I can be fully turbo charged by then.

Well I certainly have not forgot about this car. I just have not posted as I have been busy with work and "vacation" at World of Speed in Utah.

But I have made a lot of progress. I have wired in the knock sensor, swapped ecu cases and installed dsmlink, installed and wired in the wideband, installed and wired in the MAP sensor, wired in the IAT sensor, built the exhaust, installed two 12" fans, installed the turbo, installed the oil feed line for the turbo. I am sure there are a few more things, but I am getting close. Oh and I removed the PCV to vent the valve cover with a straight through barb.

All I have left to do is build the intercooler piping, install the injectors(high impedance so no resistor pack) and order the couplers and clamps tomorrow for the intercooler piping. I hope to have the car running no later than wednesday. This will be a pump gas only car so we can take it anywhere any time. But I am close and excited as I have been playing with two other automatic turbo dsms lately.

I'll be the first to say it. That exhaust is going to flow horrible and be loud as sh!t. Why didn't you go with a traditional to the back and dump it at the back seat or something?

Well it won't be loud as this is a tame little N/A 1.6L being converted. But I am sure it will flow like poopoo, but I was not going to budge on a few of the ideas I had going into this. While it is not perfect, it came near what I had in mind.

I wanted to be able to change the oil easily, take the downpipe on and off easily, service the oil feed and return lines easily, service the alternator easily and not hang down super low. I based all of this that I wanted the exhaust to go out the front bumper. I went out the fender before and would have loved to have done it again, but keeping the power steering and alternator in their stock locations that just was not going to happen with a stock manifold and 16g setup.

That and this being a small 16g car pump gas car, I am not looking for uber power here. That and the exhaust is only 2.5".

Why do I have to be like everyone else? That is the point is to be different, right? But I cannot stand exhausts that exit under the car. I hate the loudness of that and the drone. That and I did not want a full exhaust as a straight pipe all the way back makes a ton of noise as well. I am happy with it in all its ugliness. I have worked on a few that came out below the front bumper, and I did not like them. The look and flow did not concern me. I really had to have it pretty much like this. I just wish I owned a few more tools to make a few of the bends smoother.

Fixed - I'm with fastvtgsx. Your car but, :vom: on the exhaust

Yes, being different is welcomed; if it's innovative and offers an alternative to the norm without a sacrifice in performance or safety. There comes a time when you have to realize that certain things are done a specific way because there has been years and years of design that has been iterated on by some of the top minds in the world. The best concept has already been proven and the method(s) used to implement that concept are being dialed in to the point where without new advances in materials the edge of optimization has already been reached.

An exhaust is a very complex system when you get down to it.

Plus at lower speeds with the O2 sensor so close to the tip of the exhaust (that points forward by the way) you are going to get grossly incorrect readings because of the inflow of fresh air. The car will not only sound like poo poo it will run like it too.

Pointing forward makes no difference and I am quite certain it will run just fine. People will find a way to bitch at something I do unless I go and buy someone's part and be just like everyone else. While I am subject to criticism posting this stuff, I truly don't care. You could tell me time and again, but things aren't going to change. We have been running short exhausts for a very long time and have never had issues with our readings. I am no engineer, nor do I pretend to be one. This is what works for my car and what I need to be able to work on it. You build your car how you want and I won't tell you why you are wrong and who invented the internal combustion engine. I could give two shits.

I could have done I nice swooping exhaust and likely made it near the location it is at now, but it was no going to happen and ground clearence stay acceptable. George had something sort of like this on his mirage and it came out underneath the bumper cover. It was horrible and burned his bumper on top of that. Not so good looking on a white car.

I would be glad to show a video of how horrible this car runs in the next few days. I am always glad to prove the experts wrong and show them automotive engineering is not as complex as they think it is.

We can't know if we like it without clicking the link and seeing it. :lol:

Don't take everything so much to heart dude, if it works for you then so be it. No one to please but yourself like you said. I've welded up plenty of ugly shit, as long as it works, who cares. I was more concerned with the 90* turn that exhaust makes like right after exiting the turbo then anything else with the design. If it doesn't turn out so great, then you can always modify later.

Crunchy has a point with the o2 sensor, if a small exhaust leak at the o2 housing can screw up the reading then that location can definitely effect the readings as well sense it's so close to the exit. At WOT it won't matter but at light throttle and low rpm it might cause some problems.

I just wish I could get away with a exhaust like that in my area! Even if it is only 2.5" that things gonna be retarded loud to surrounding traffic. I for one love a wide open exhaust especially on a turbo car. I say "your car" "your build" but a little constructive criticism never hurts. :wink:

For someone who truly doesn't care about criticism from others you sure make a quick jump to such an extreme aggressively defensive attitude in your responses. Personally I'd prefer to see you not buy someone's part and make your own, but to take some time and not just cobble anything together. Another 2 hours, a few more pieces, and rotating the "tip" so that it had some protection from incoming air and this could have been a well made piece.

In open loop (WOT) it will run just fine because the exhaust flow *should* overcome the incoming ambient air. In all closed loop operation (idle and part throttle) it will run pig rich because the additional incoming clean air will be read by the O2 sensor as a lean condition. This will make setting your true Global on Link difficult because you will be perpetually correcting for a condition that can't be overcome because of the front facing exhaust and proximity of the sensor to the tip. To overcome the lean condition at the sensor you may end up dumping an absurd amount of fuel into the engine. I don't think I need to explain what that will do.

Is this going to ruin your engine? Not so much. It just won't live up to it's potential. I guess I figured you high altitude guys would be scrapping for every bit of performance you could get to offset the less O2 dense air.

Again, not trying to start fights.

Well I am not going to hold my tongue for anyone. And seems as you guys are so observant and all, that is the Wideband, not the factory o2. So you just wasted who knows how long in your life typing that crap up. The car is going to run just fine. Amazing how people think the world will end if something is not the same way that everyone else has done something since the inception of these cars. My car just might implode and kill me and everything around me for a piece of steel being out of place. OH NOES :roll:
