- I just bought this car from another member on this site. He did an amazing job building the car! The very thorough build thread can be found here.. http://www.dsmtuners.com/threads/bkrathwohls-galant-vr4-1228-2000.499214/
I plan on completing the finishing touches on the car and driving it! He had it dyno'd at 319 awhp last fall on 93 octane. I may look to switch to E85 in a few months to see how much I can get out of it!
Update
Flashback to 2018... I found out the reason that the car only made 319 hp on the Dyno. The tuner couldn't go for more power because it would start knocking... I did the switch to E85, turned up the boost and started tuning. That didn't last long - I quickly developed Rod Knock... I parked the car until I could source a new engine and swap it out...
Upon reading back in the build thread, I discovered that the engine had rod knock before and instead of a proper rebuild, new rod bearings were installed... No wonder that it failed again...
I sourced a new engine from my friend. My most excellent friend gifted me (and my wife - a wedding gift!) A running 6 bolt with a 2g head. The engine had previously been rebuilt with eagle rods, and wiseco pistons, arp headstuds, balance shaft delete, and 272 cams. I had no time to install the engine though...
Flashback to 2019... I removed the donor engine from the parts car and removed the blown engine from the Galant...
Flashback to 2021... I was having trouble finding time to work on the car, so I enlisted another good friend to install the new engine for me. I worked out a deal with him. He installed the engine and I paid him with the rebuilt 1g head that was from the Galant - it was a win-win situation!
We got the car fired up, but there were a couple of issues. One - there was a small oil leak from the oil pressure sender and two - the idle was surging very badly. There was a bad idle surge with the old engine as well. Thinking that the throttle body needed some work, I decided to source a non-Turbo throttle body... Still having trouble finding time to work on the car, it sat in storage for two more years...
Fast Forward to August 2023...
The oil leak is fixed - the sender was just loose! A few turns to tighten it up and no more leak...
The Non-turbo throttle body is installed. This along with some tuning and more importantly - changing a wideband setting in dsmlink, and there's no more idle surge!
Now it's time to dust it off and start driving it!
