E99 turbo conversion
The start, I converted my e99 to new style turbo. I installed bellowed up pipes, I used the .84 exhaust from e99 and the 1.0 compressor from a 2003 van, the old turbo had a ww and now I use the compressor from the 2003 van. Of course I had to install a taller pedestal, I'm still using the stock exhaust, and removed the ebp gate, I have super chips tuner, and napa 6637 air filter.
As e99 setup with tuner, exhaust temps would hit 1200 wot & 20 psi, and at 70 mph I would have 3 psi and 300-500 exhaust temps. Idol is 300 degrees,
New set up with tuner, wot is never over 1000 degrees & 25 psi, 70 mph is 600-800 and 5psi, idol is 400 degrees,
Now the question, I thought that temps would be lower? Are the higher temps ok? Should I have changed something else? I will be doing 4" exhaust next, but I don't want to hurt my motor running higher temps. My goal for this project is better mpg, not power. Any suggestions would be appreciated.
