Mark's 1G Winter Projects

With your Magnus V3 or without? :-( Mine still hasn't shipped.

Nope, I wish I was. They said that I will get it next week, again.

You are a fukin rip! I'm very very impressed how you got everything back together so quickly, nice work! Got any carnage pics?

Also, did you have to yank the motor completely apart or did you just yank the timing components, pull the oil pan off and leave the pistons in the block?

Just took apart what I needed to. The oil pan came off, removed the front case/oil pump, and unbolted the mains and rods. Remove the spark plugs and then pushed the pistons down in the bore. Then I just swapped out the crank. It was about a 3 hour process with the motor out of the car, cleaned all the main and rod caps, gasket and bearing prep, and installation.

Kind of cool, I primed the oil system with the engine on the stand, using a drill on the oil pump with the pan full of oil. I keep the turbo drain line on the pan so oil didn’t leak out. To my surprise the drill on high speed was not enough to prime the system. The oil filter was too much of a restriction to pull oil into the pump. I removed the oil filter and spun the pump and it pushed oil out of the filter housing, spun the filter on and continued spinning the pump for about 3-5 seconds until I saw oil coming from the turbo oil feed line. Primed. So I doubt that the oil system will prime on a new motor from just turning it over, like people think it does. My drill spins the oil pump much faster than the starter does turning the motor.

Only made one pass had a BOV weld/material fatigue issue. More than likely due to my welding, did this like 6+ years ago.

Lost some boost to a leak, assuming this started to crack in 3rd gear. Then at the 8K mark in 4th gear it let go. It was still was a great run. The launch was a 1.61 60 foot. I was very happy!

Thanks! My wife and I had a great time this weekend. I knew you could get that 11 second pass! I was not around for the final. I passed the green party machine on the way home, I ended up calling Jim. If I'm not mistaken he told me that you won the stock appearing turbo class. FTW, Great job!!

Nice work Mark! Cannot wait to see what it runs with that intercooler pipe fixed!! Nice Seeing/chatting with ya again this weekend!

Yes always a good day to get into the single digits, and hang out and BS all day.

I had a chance to peak at John’s logs at BIR and noticed that his 2.0 spooled a non BB 4202R faster than my 2.3 powered PTE BB 4276R, it also had better boost recovery between gears. Now thinking something was incorrect with my setup I built a boost leak checker, fixed the IC pipe and tested the system. The throttle body leaked so bad I could not even build positive pressure in the system!
So now for my update, I ordered a Magnus manifold months ago, it arrived about 2 weeks ago and I immediately started fabricating new piping and others. I could not fix the boost leak in the TB so I purchased a Wilson TB and welded my v-band to it. The car now spools the turbo over 500 rpm quicker. The power comes on very hard and the recovery is better between gears, still not as good as John’s, as I have lots of IC piping and a 6” thick IC to fill up on every shift.
