My 2014 Refresh/ 6G74TT conversion

If I had thought about it, I would have warned you on the rear main seal. I have a pic of it somewhere...



74 on left, 72 on right. I didn't know about the water pump though... I used all 72 stuff on mine

seen that before

I'd have just drilled the pan for the new location...

Thanks VR4Man!

Gump, I would have drilled the pan but the wall rolls up right under the bolt hole. Drilling and tapping might be an option, but I don't know if it's worth it. If anything I'll hunt down a 72 TT rear main seal housing for next time.

So after getting the pan on and sealed up I realized I couldn't turn the engine over anymore. The crank was hitting the pan in three places.

One on the top of the lip on the back side of the engine



The other two spots are above the t-case



After taking out some frustration over the whole deal with a hammer and several test fits later they finally cleared.

I am usually a little better researched when doing this type of thing. The TT and AWD conversions went much smoother than this.

that's a PITA. at least you figured it out quickly!

It's getting down to the wire to be ready for NG and I just got the engine dropped in last night. I wouldn't be worried about it but I have to rely on an exhaust shop to do the downpipe. If a vendor sold one for 6G74 conversions I would have just bought one and sold the one I have (Pssst, you! hint hint)

Anyway, there were a couple more things that needed modified before it would bolt in.

I quickly measured the rear engine mount boss on the 72




Then compared it to the 74, you can see the gap at the end of the stick. This is actually deceiving, I had to grind away much more than just that little bit. The top mount bolt's boss is actually where it needs to be (no grinding required) and if you hold the mount up to it you'll see an acute angled gap. That's pretty much what I used for reference. You can see a gap now at the other end.



Judging by the aforementioned acute gap I actually needed to grind a little more, but the measurement taken from the mounts in the car and the brackets on the engine were within and 1/8" of the 26.5 they needed to be. It dropped in no problem, but the support bracket to the rear of the trans doesn't quite line up, so I'll be revisiting this next time it comes out.



I had to make an adjustment to the water line to the turbo, it was too tight for me to trust the hose not to kink so I added a 45 degree dude in there.



The engine to trans plate thing (technical term) needed some clearance to for the rear main seal housing. 45 seconds with the cut off wheel took care of it.



I spent a little bit of time cleaning up the engine bay and hitting the subframe with some fresh paint.



I dropped the engine without the trans because it's a pain trying to get the trans to go onto an engine swinging from a hoist.



Turns out to be a tight fit with the hood



Then used the hoist to pick the trans up and a jack on the floor to level it as I slide it onto the engine ever so easily.






I got the transmission, t-case, axles in, and hubs put back together tonight. I also messed around with the catback, unfortunately I removed and/or broke (and lost) the mount by the gas tank on the passenger side so I'll have to get one from Mitoska.

The car is back on it's wheels and I'm going to take it to the exhaust shop after work tomorrow. They work from noon to midnightish so it would be awesome if they got it done tomorrow night. I'm hoping they work Saturdays if not. Otherwise I'll be finishing it up on Monday and taking it to PA on Tuesday.

Hot digity!

Super excited to do a ride along.

Quick update before bed.

The guy that owns the exhaust shop was nice enough to work on a Sunday, he was extra nice enough to let me help. He usually does GTR/Corvette exhausts and turbo set ups, but of course he'll make an exception to work on my 3000 and take my money.



While he had the down pipe on the bench doing the finish welding I was clearancing the subframe. I also hung the IPS catback while it was on the hoist, I forgot to take pictures, I'll get some tomorrow.



We ended up just adding this spacer and with the clearance made above the downpipe fit great. He wasn't very happy with the aesthetics of these welds, the pipe was very oil/grease contaminated didn't make for pretty welds. I'm just glad it's functional and done.



I towed the car back home and got all the fluids filled, the wire extended for my oil temp sending unit, and all of the accessories bolted up and the belts on.



I moved over to this side and got the slave cylinder reinstalled and then just decided to call it a night.



Going to hit the DMV in the AM to get the tags switched back over to it and get back to work on it. I hope to have it running by the afternoon sometime. I still need to gather things and pack for NG!
