The boosted ls/vtec build is finished!

[boostin4fun]

Well my cheap ebay turbo manifold finally bit the dust! It lasted for almost 1100 miles. So that is probably a new record for the longest lasting SS Autocrome manifold, lol! I recently got a new MPRD equal length turbo manifold for less then $300. My friends have used the same manifold and it holds up really well for its price.

Here are pics of the new manifold with the turbo bolted back up. I had to replace the turbine housing because a bolt for the down pipe broke off. I tried to use an easy out to get it out and that broke off inside the bolt. So I was basically screwed and just ordered a new housing, that was alot easier .

Since I have to make a new down pipe I decided this is the time to upgrade the exhaust all the way back. I was running a Greddy evo2 exhaust before which was way to restrictive for my setup. So I purchased a 3" bend kit for a civic chassis and decided to build my own. I also bought a universal Apexi world sport2 turbo muffler with a 3" inlet and some 3/8 bar stock to make custom hangers to make it all work. Here is what it looked like to start.

All I have left is to make the new down pipe which will be 3" also. I have to buy an accord slave cylinder so I will have enough clearance to squeeze it in. I also got rid of that FMIC it was way to big. I ordered a new Greddy intercooler which is sized much better for this setup. I cant wait to get it all together with a new final tune.

Well I finally got the exhaust all done and put back together. I never did receive the smaller Greddy intercooler I ordered. It was coming from Japan and still hasnt arrived so I am using the old huge one.

Here are some updated pictures with the new manifold and exhaust.

The bigger exhaust significantly leaned out my old map. I have drove it for about 100 miles since the work and have a pretty good street tune on it right now. It is between 11.2-12 AFR in boost all the way to red line. It pulls way harder then it did before. I dont know what kind of numbers I am making but very likely 300whp because I am already at a pretty high injector duty cycle with 650s. I am running about 12psi and I am thinking of going for 14 or 15 and getting some 750cc injectors. But then again I am pretty happy with it right now!

You're a great inspiration man. Great job. Enjoy the rep.

I am glad you like the build. I need to come up with a camcorder so I can get some video footage up. Maybe I can talk my sister into letting me borrow hers.

nice build i only wish i new half as much as u do about hondas man

 

[boostin4fun]

Yep I definetly outgrew the 650cc injectors I was running. I was at almost 50 psi of fuel pressure with 90% or slightly higher duty cycle. So I put in some 750s and turned the fuel pressure back down to 44psi. Duty cycle has gone done quite a bit so I feel alot safer.

im in the works of doing an ls/vtec turbo build as well and wat i would like to know is how did you get enough oil to run to the vtec head and the turbo..thanks by the way nice build

 

[boostin4fun]

You can do it several different ways. Some people like to buy the sandwich plate that allows you to run lines from it. If you want to go that route I would get this sandwich plate because it is afforadable and well designed Generic Oil Plumbing Kit On my setup I have a t-fitting installed where the oil pressure sending unit is, that is where I ran a line for the vtec conversion. There is another plug in the head right by the water neck that is brass colored or maybe it is brass anyways, I ran a fitting from there to supply oil for the turbo. I have had this setup together for sometime now with absolutely zero oiling problems. Either option will work well.
