succesful K8 turbocharged @10 psi!!

[2RotorsNaDream]

Damn I used to know this one back when I had my RS. Its a B-series engine but I dont remember which one exactly. Do a search its easy to find out I just dont remember off hand. Sorry.

[VizualXTC]

The RS has a B6 engine either a SOCH or DOCH, either way, a B6. <p>Batt: Sweet man. I'm glad to hear that you finally got it done. I've been waiting. Throw a G-Tech on that beast or get it to a dyno, and tell us what kind of power you're puttin down. I imagine close to 200WHP. That'll be nice. I'm givin up on my friend who is supposed to be gettin me a turbo, so I should be pickin one up this weekend, gettin ready to piece my turbo setup together. I do have one question. I forgot how you are getting the oil from the turbo to the pan. Did you mount it high enough that you still have it gravity fed? or are you using some sort of a pump? Where did you get the larger injectors from? Did you try runing stock injectors with the Walbro pump? You should IM me or email me and we should chat about it again. Also, if you need me to host pictures, you know where to send them. Peace bro, Hell of a good job btw.

Saweeet Bottsai! Can't wait to see some more pics of your progress!

ha ha ha, thats funny

[BATTOSAI]

Hi guys!
first of all I´d like to thank everybody who has helped me and gave me his support ( you know who you are!!) and all the other guys who show interest on what I have been doing.<p>I´sd like to explain a bit more detailed how I planned my project:<p>First of all, I don´t like those setups where the turbo is visible from the engine compartment, as I think that it´s harder top keep the heat out from elements such the distributor, intake tubing, hood paint, and electrical connectors. So I opted to use the space where the oil filter assembly sits. I had to build two flanges with the same shape than the assembly and interconnect them using 8mm inner diameter oil tubing. I actually have the oil filter beside the power steering reservoir. As soon as I had the room for the turbo, I figured the exhaust piping routing. I cut the stock "Y" pipe past it´s union and build the system from it. It goes around the oil pan, passing under the belts, and then rises up to the point where I was able to fit the T3 turbo. As I had to pass the downpipe between the front cilinder bank and the oil pan (is where I found it better) I had to enlarge both Y pipe arms about 3 cm, so I would have more clearance and won´t drop the piping to the ground.Then I built the downpipe with the flexpipe to the stock flange of the catback piping( Now I´m working on building a larger diameter catback system as stock looks thin) I fed oil to the turbo taking it from my oil filter relocation kit. I tapped from the line which come out from the engine, and wired to the turbo with a 3mm copper tube, which looked very comapct. I used the stock drain line of the turbo and routed it to the oil pan where I had previously added an oil port above the oil level. I have enough drain force to take the oil out, as if I stop the car and take the line out, it looks empty. For the fuel system I bought a vortech FMU, a Cosmo Racing AFPR, an Apex'i s/afc , a set of 220cc/min Kl injectors and a Walbro 255 lph fuel pump. I had trouble with the AFPR ,so now I was reducing the fuel flow with the only help of the S/afc, which causes a small bog if you stomp on the throttle hard. Otherwise, on idle, part throttle and full throttle I have a good a/f ratio. To monitor all engine vitals, I have installed a A/F ratio meter, the vacuum/boost gauge, an EGT (exhaust gas temperature gauge), and fuel and oil pressure gauges.
I have the intake tubing made with aluminium tubies and stainless elbows connected altogether by connecting hose which can stand up to 18 bar. I use an intercooler that I purchased from my local junkyard which has the same size and look than the one used in the mazdaspeed protege!. I installed it in the well that is below the drivers side light, cutting some metal and using the fog light port to fed it with fresh air ( i know it´s not a good setup, I will go to a FMIC setup. I use the other fog light port to keep the air filter fed with fresh air. I use a blow off valve out from an audi ( don´t know the model) which was adjustable, and it makes a nice WHOOSH! take my foot of the throttle!
Well, you can see that if you put all the items on the table, I haven´t spent too much money, but I had a lot of work putting it alltogeter!<p>I´d love to take it to a dyno, but I had a small leak on the radiator, which caused an overheating, and now my vacuum gauge reads 15mmHg at idle, which means low compression, so first of all I ´d like to fix it before it gets worse!!! <p>
Feel free to ask me the questions that you want, I´ll reply them pleased!<p>[ September 18, 2003: Message edited by: BATTOSAI ]</p>

Here is the link where I had some pictures of my progress (courtesy of VizualXtc Thanks Ryan!)<p>http://www.mx-3.com/cgi-bin/ultimatebb.cgi?ubb=get_topic&f=19&t=000498<p>As soon as I won´t be so busy I´ll take detailed pictures of everything!

[mrspanky79]

I would suggest changing back to the k8 injectors. I put in the kl injectors when i did my tubor and to get them to run right air/mix i had to drop the fuel pressure to 35psi the lowest I could get it and it still runs rich at time, under boost verry rich. And after a year of running it like that I know have lost compression in two cylanders. When you get too much fuel in there you wash the oil off of the cylander walls and burn out your rings. Go with some kind of secoundery injector set up so you only get fuel when you need it under high boost.

[BATTOSAI]

Yeah, that´s right. As soon as I have my actual problems solved I want to go with the kl injectors, 10:1 fmu calibration (now 12:1) and narrow the injector pulse a bit on the midrange with the help of the S/afc. With the setup I´m developing on a Kl engine I will be using two set of injectors with an electronic control system. I can´t get more than 5 psi with the K8 injectors without going lean, and actually I am running 10. It´s true that I didn´t test the K8 ones with the Walbro 255 fuel pump, but I would need quite a high pressure to achive the fuel flow needed.<p>[ September 18, 2003: Message edited by: BATTOSAI ]</p>

nice, how many hp do you expect

[BATTOSAI]

It´s hard to tell how much horsepower do I have. I am using the stock clutch and I suppose that it doesn´t hold the power very well. I haven´t riden many powerful cars, but I can say sure that it has at least 180 hp ( 180-132=48 ,it would be a fair amount!) but seeing the results obtained from the BP brothers that get 200+ at more or less the same boost makes me think that maybe a few more. Now I am a bit on low compression due to an overheating (the vacuum gauge reads 15mmHg after that happened, before 20mmHg, but I will take it anyway to the dyno. I am sad to say that I won´t expense more money on this engine, as it has quite high mileage, and I received a Kl engine which I want to rebuild it's bottom end. If I get mad, maybe I´m replacing the head valves for ones bigger, but I´m not in one of my best economic moments! What I must get for sure is a clutch, I was thinking on ACT, but I must investigate a bit more on other brands and their result. If anybody knows a good deal on those items for the Kl I would thank any help possible.

[nope-mx3]

could you please list everything you have done?

wich parts, wich mods for the turbo setup to work.
would be very helpful

[BATTOSAI]

Man, I think I explained the best I could some lines above! if you have a more detailed question I´ll reply it pleased!
Thanks for your interest
