Has anyone ever swapped this?

Yeah my reason for steering clear of the vr6 was wiring. Since I discovered how nice a carb works, I will only use that. Contact 034motorsports. They are very helpful. Tell them what you're doing. They have helped many people in the past. They will know exactly what to do. You might be able to keep your stock trans and use a bellhousing adapter plate. That's something that's easy to make with a CAD program and have a machine shop cut it for you. But you will run into issues with a custom flywheel+clutch setup.

OBD1 and 2 is easy to identify. take off the valve cover, is there two sprockets or 1 per cam? 2, obd1, 1 sprocket, obd2. You will have to use a custom vr6 flywheel that will mate up with a rx7 clutch if you use a rx7 trans. if you use a audi trans, modded vr6 flywheel with audi clutch. There's a lot of things you can do without on the motor, Secondary air intake system can be deleted. the wiring harness for the motor is very simple. it has a big connector that connects it to the rest of the wiring of the front of the car. AC is easy to delete. You just take it off and go to napa and get the right serp. belt.

2 Sprockets per cam...I actually have the engine completely apart right now but I could build it more towards turbo or N/A at this point (cant decide...) I'd like to keep cost down on this so retaining as much RX7 as possible would be great. I recently lost my job too so until I get another one, its all planning, tearing apart, and cleaning haha
Forged rods is what the OBD1 motor has along with a forged crank.

What was your power goals again? The OBD1 motor is better than the OBD2 motor. But for the life of me I can't remember exactly why. Just turbo it. You don't need a huge turbo. GT35 is too big. Buy a head gasket spacer. Just do gaskets on the motor. Don't tear it down to rebuild. It has plenty of life left. Many people start to turbo these around 100k. You're not even close to that yet. Just make sure you have reliable tuning, either standalone or c2 and keep your temps down. That motor is like donkey. It will hold up.

I'll look into some popular tuning software with the VDub guys. My friend has a stage 2 WRX and he uses a UTEC and I like the layout of that software, so something similar would be cool
I know these engines will last forever, Only reason I took it apart is because it had been sitting for years so It had gotten a little wetness inside the cylinders that I'm just gunna either hone out or get it bored
I messaged 034 Motorsport and I'm just waiting for their response now..They'll see "VR6 and RX7" in the same sentence and be like wtf kid... lol

I take that back. Inline sixes are second only to 3 and 4 rotor engines in my own personal opinion....which this thread did not ask for but it's a public forum so you're getting my 2 cents anyway.
Inline six=like a bawssssssssss.
Buy ****, make it happen and dont bitch out like every other person with an idea they'd like to piston swap their rotary car.

i dunno my triumph had an inline six and it only had like 85hp-
you guys that hate this idea just have no creativity and think the only good swap is one that someone else has already done. the vr6 a bad *** engine.

VR engines seem to have an uncanny ability to spool massive turbos with ease, a mix of the capacity and the great flowing head I guess.
Ive seen a R32 motor running a massive borg warner S400SX3 (S475) see 15psi under 3500rpm and see 600+@wheels and similar torque at that boost level too.
If they arent crazy tall, and can be bolted to a RWD box easy, and a sump wont be a big deal, they could be a good call over here in the UK- They cost peanuts here, I've bought a rusty but complete Mk3 Golf VR6 for £100 with only just over 100k on it in the recent past.

Bah. Shows what i know. I'm just trying to start a fight apparently. I hate vw for personal reasons.
I love old school 13b powered beetles that do wheelies though.
Vr6 motor is what? I could google but this is YOUR thread so go ahead and make it awesome.

I had plans to do it, but decided to scrap the idea after buying a ton of parts for it, mainly since I couldn't find a local place that would make the bellhousing adapter.
Here's a thread I started on vwvortex (I guess I deleted the pic, it was of the T2 trans sitting on a vr6 engine to determine the thickness of the adapter)

Just going to drop this here:
http://forums.vwvortex.com/showthread.php?2876938
VR6 Corrado using a Ford T-5 transmission. The owner says he built a custom adapter plate but the clutch/flywheel setup is still a mystery. It originally only piqued my interest because he used so many Conquest/Starion parts [why I'm not sure, there are so many better/easier-to-find setups for cheaper].
I had considered this swap for my Starion actually, but the one-off machine work required to get things to bolt up would keep it from being worthwhile to me. The stock turbocharged forklift engine in mine will produce 500lb.ft. with relative ease, and so long as I can still get bearings for it, it'll stay.
