Are you planning on trying to get this build through a CA smog check?

Good luck on the project, BTW. I look forward to seeing how it turns out.

The AEM has a programmable 0-5v output that could be set to emulate the range of a narrowband sensor.

 

Aren't narrowband 0-1v?

Bosch LC-1 also has a programmable output for narrowband.

 

Yes, but the AEM UEGO is 0-5V and has a programmable output as well, but thats only good for a standalone such as MegaSquirt

 

I don't know what size pulley you plan on using on your SC nose but I doubt you'll need anything bigger than the Walbro 190 FP. That's what the URD V6 SC fuel kits come with, and its working good for me at 10+ psi of boost.

I do recommend running a new dedicated wiring harness for the FP straight from the battery and just use the old FP wiring harness to trigger the relay for it.

I think I would have used a turbo for what you're doing but I don't know the race rules for what you have in mind.

 

Thanks for the info. I am only running a 255 because I have it laying around. If I were to buy a pump, I probly wouldn't buy the 255 because it's overkill.

Could you explain a little more about recommending a new wiring harness for the fuel pump?

And as for SC versus turbo, I wanted to go SC, more as a appeal and project. Between all my buddies that own VR-T VW's, Audi, and Mitsubishi Starions, I'm kind of burnt out on working, seeing, and building turbo motors. At first, i was going to turbo this truck, but figured I'd have more fun building a SC for it, and it will also get alot of looks and "ooh-aah's" at my local meets. I'm pushing for 200CHP.



I got to finish my custom pulley last night, and I will give you guys the low down on it in the next little bit. I gotta get pictures up too.

 

The factory wiring harness to the FP is tiny stuff, add to that 15+ years of deterioration, plus the FP is very voltage dependent, plus a bigger pump needs more amps and you could have a problem. At LEAST check your voltage drop on it.

 

Gotcha. Didn't think of that. I will check it out, thanks for the idea!

 

I haven't made much physical progress lately, so I don't have a whole lot of write up to do. I do have the custom pulley I made already on the truck and ready to go. I do want to just keep this updated cause I don't want this thread to die.

I have been waiting on my header that I ordered. It should be here today. I didn't want to do any more work until I had a header on, because I may be able to make brackets and/or mounts that work around the header. Last thing I wanted to do was create all the mounts using a stock manifold, and then have to switch it up once I got a header.

I was also on the lookout for a diverter valve and a rising rate fuel pressure regulator. I found both but have not got them yet. I'm hopefully going to be going to the junkyard tomorrow to be scouting and looking for a good tensioner set up.

 

Any reason you can't mount the SC on the pass side like the LC kit does? I was just thinking cause of the header being right there might not be a good idea. I want to do this as well with my 22re but at 10.5:1 I can only get away with 7psi max. Keep us updated.

 

You have a good point that has been brought up by many people, because there is in fact a lot of room on the passenger side.

The reason I am not mounting it on the passenger side is because of simplicity. The amount of design that it's going to take is going to be about the same, whether I mount it on the passenger side or the driver side. The reason I decided on the driver side is because when it's all said and done, the outlet of the supercharger will be in the perfect spot for my intercooler. I have the FMI (front mount intercooler) already set up, and with the SC outlet on the driver side, I simply route my piping to one side of the intercooler, and then the exit side of the intercooler is very close to the throttle body. If I were to mount the supercharger on the passenger side, then I would have to pipe all the way to the driver side, and then back to the throttle body.

Progress has been slow lately due to a very very busy schedule, which is also the reason I haven't been on here much lately.

BTW, this motor and complete drive train will be for sale shortly.

 

Why are you selling it?
Swapping to a honda or other toyo engine?

 

My brother bought a 6.0L and supercharged it for his truck (GMC Sierra), so when I swap it in a few months, I'm taking his 4.8 V8 and it's going in this truck. I have about 3 months or longer before this happens though, which is why I'm still going to finish this motor.

 

Progress is being made. Between working two jobs, finishing up school, and partying, I never really have time to sit down and just work on this thing. So, that being said, I threw my buddy some cash and he is fabricating the system for me. He took my truck for a few days. Anyways, got it mounted. I ordered my intercooler piping kit, so I can finish it up. I'm off to the junkyard to piece together an idler and tensioner setup. Once that is on, I can pipe it and it'll be done. I'm hoping engine will see boost within 2 weeks if all goes planned. Got my motor built and now 20,000 miles later I'm finally finishing it...LOL

 

dood, sweet!

 

Just got back from the junk yard. Got the idler and tensioner that I need. I am busy tonight, but my buddy may be picking up my truck again later to work on it. Waiting on my intercooler piping, but the bid is still going so I won't have it till next week anyways. I'm starting to get pumped up! Lol. Too bad it's getting a V8 soon

 

what's done to the motor, internal-wise? how well do you think it's going to handle the boost?

 

Awesome fabbing! I still want to hear how it sounds, though!

 

Big valve head, 6K springs, EB 261C cam, ARP head studs, on cast pistons, and is fully balanced. I have no worries on motor until 300hp, although I will never be there on this motor. Only planning on running roughly 8 lbs of boost.

If I had a good camera to take a sound clip, I would post it up. But I don't, and anything under good quality just distorts the sound and it sounds nothing like real life. It's pretty much a setup that is a once in a lifetime, and in person is the only real way to hear it.

 

This is sick. Im diggin the 2 bike pipes, must sound gnarly.

 

I understand. If you ever get a chance to record it with a better camera, though, please post it up!
