10vt into my 80q(the Bandit) :: motorgeek.com

Well here goes nothing. I have a 91 80q that I am looking at doing a 10vt swap into. I already found the doner, its a 5kq avant w/ MC1 turbo already chiped to 14psi (or so I was told) . I know Im going to need the engine, ecu, and wiring but not sure of what eles. Also other than needing to fab a down pipe and intercooler piping, is there any other fab work or mods I will have to do to the car its self? Ive been working on cars for a long time but this will be my first audi swap. I was told by people on other boards to ask the guys here at motorgeek because there were plenty of guys who knew this swap well. Any info and advice you guys can offer would be great. Thanks in advance :thanks:

plans for the winter
MC1 turbo swap
Rebuilt 01A
res. delete w/ stebro rear exhaust
5 lug swap
Delrin CA bushings F&R
Alum subframe bushings F&R
g60 up front
B&G s2 springs
& what ever eles pops up :-)

Any body? Ive been looking through old theads now for three days, and cant really find much as far as the small parts.
-Should I use the 5k's MC mounts or the 80's NG mounts?
-What clutch, PP, and flywheels setup should I go with?
-Should I use the 5K's exhaust mani, or should I look for the "upgraded" 200 10vt mani?
-Should I use a k24, k26, or possibly a k24/26 hybrid?

Im looking for and advice and sugestions you guys might have
Thanks again

I have not done a 10vt swap in like five years, its been all 20vt's and v8's, but the other little thing you are going to need is the passenger side inner tie rod end for the B3 chassis with a 10vt. The waste gate placement on the 10vt interferes with the stock inner tie rod. I'm pretty sure I've bought a couple from 2 bennet over the years but someone here probaly has one kickin around. See if you can get the down pipe from the doner car because with a little modification you can use that. The 10vt exhaust mani is known for cracking so check out the one on the doner car if its cracked, which it probably is, ask around here for a good one. I would go with a k24 from an MC2 I've always had better luck with these over the K26. What made you want to go with a 10vt? is the doner car real cheep? 20vt's and V8's have really come down in price and then you don't have to deal with CIS and you'll have more power!!

Niether, use Mustang Energy Transmission mounts.

-What clutch, PP, and flywheels setup should I go with?

- Pop the pilot bearing out of the crank and use NG or 7A FW and Clutch. You can resurface your current flywheel and get a 7A disk for the cheapest route. The 7A disks are bigger. Depending on future mods, you might go with aftermarket

-Should I use the 5K's exhaust mani, or should I look for the "upgraded" 200 10vt mani?

If you can find a 2 piece manifold that would be nice, but minimal gains really.

-Should I use a k24, k26, or possibly a k24/26 hybrid?

Run whatever turbo the chip was built for, if it will do either, go K24.

Im doing a 10vt swap because Im picking up the 5k avant for a steal at $250 because a tree fell on the rear. As far as a V8 swap goes, im working on a 4.2/01E(6spd?) swap into another B3 with a good friend of mine. Im doing a ton of work for him and in return im getting a ton of parts, so Im almost going to get this done for free

. I also saw in a few posts about the manifolds cracking so I guess it a good thing Im a machinest,welder, fabricator. :thumbsup:

Thanks for your Help :cheers:

Why use the mustang mounts? Im getting a set of 034 street density B3 NG mounts for free. would it still be worth it to get the mustang mounts? For the clutch, I should reuse my NG flywheels with the 7a disk. What about the PP? Should I go with a 7a on that too? I think the chipset was designed for the k26 (dont quote me on that). I pick up the doner next weekend, time permitting, and hopefully have the shell in the yard the weekend after. As soon as I get to talk to the PO again I will find out where the chip came from.

Thanks for your advice on the "cheap rout" thats the way im going for now :-)

Yes, 7A PP.

One thing, If you are going to run the MAC ignition, you will need timing pins in the flywheel. I can't remember if the 7A had the same pis or not. If so, get a 7A flywheel as well.

7a has the correct pin, I have a 7a flywheel for sale, as well as lowering springs if you are interested.

So the NG FW wont have the pins? Also, did you get the mustang tans mounts for the old fox bodys?

If I would need it, how much shipped to 17403?

mr_aj_johnson · **Posted:** Thu Oct 20, 2011 9:03 am

50$ plus whatever the usps flat rate box costs

audifreakjim · **Posted:** Thu Oct 20, 2011 9:12 am

I searched, there are lots using them here. I have had mine on for 7 years and they are still going strong.

1980-95 Mustang 5.0L V8
1979-86 Mustang 4cyl
1979-84 Mustang V6
Transmission Mount

OK i will do some research to see if i can use the NG FW with the 7a clutch & pp as well as work with the MC ignition. I will get back to you asap

Thank you again for all your help. I will look into them. Other than power was there any other reason you went 20vt?

audifreakjim · **Posted:** Thu Oct 20, 2011 9:58 am

From a design and engineering perspective, the 20v is better in just about every way. Packaging, maintenance, flow, combustion chamber design, etc. The 10vt is great bang for the buck, but if you start thinking bigger turbo's, just go 20vt and don't waste money on the 10vt.

mr_aj_johnson · **Posted:** Thu Oct 20, 2011 10:17 am

You can use the ng flywheel. You will need to add a timing pin, and have it resurfaced to accept the larger 240mm disk

I had thought about going 20vt but I couldnt pass up the deal I got on the 10vt doner. I figure I will play with the 10vt, and when my other 2 cars are paid off (2 years) and can afford to go bigger, I will upgrade then. I dont plan on getting rid of my B3 anytime soon. Its just too much fun and I love that 5 cyl. sound. :drive:

How hard would it be to locate the timeing pin on the NG fw? I am a machinest (not a machine operator) so I think I can do it. I also have 3 NG FWs so if I manage to mess 1 up it wont hurt. But any advice you might have would be great too. :-)

mr_aj_johnson · **Posted:** Fri Oct 21, 2011 9:11 am

pin is 8mm by 20mm or so. Can be purchased from dealer. Use the flywheel from the 10vt engine as a template and put the pin in the same place on your ng flywheel.

That doesnt sound like it would be too hard. Thank you for all your help with this. It looks like I will have to wait till next weekend to pick up the doner, so I have another week of research to do before its time to start. :-)

Well it looks like its gonna be another month or so till I can get the doner.

With the sudden 10"+ of snow that fell on sat. and then melted on sun. the guys property is a mud pit. :frustrated:

looks like I will have to do some of the other work to the car before I can get the swap done :frustrated:

Well thanks to rs4tech i have managed to come up with some of my parts that I needed. I now am the proud owner of the 5 lug convertion hubs, g60 calipers and correct 5 lug rotors, and a new race spec rear diff mount. I didnt want this to take this long to start but i guess all things come to those who wait. As soon as I can pick up the doner car I will post pics of it.

DE80q · **Joined:** Fri Oct 14, 2011 4:56 pm **Posts:** 4611

well FINALY have date nailed down to pick up the doner. I will Be picking it up on sat the 28th. I will post picks and parts out thread as soon as I have it. As long as it does not snow or rain untill then I should have it YAY!

DE80q · **Joined:** Fri Oct 14, 2011 4:56 pm **Posts:** 4611

Well, its been a long wait but I finaly got my doner 5k. Its in much better shape than I had antisipated and almost feel bad about hacking her up

But with the damage done to the roof from the tree its pretty much scrap. Im going back over tomorrow, hopefully, to start stripping the old girl.

mr_aj_johnson · **Posted:** Mon Jan 30, 2012 8:52 am

Take a ton of pictures! it will really help when you get to the point of "where did that wire go?"

DE80q · **Joined:** Fri Oct 14, 2011 4:56 pm **Posts:** 4611

I have quite a few pics already but when I actually start to pull the engine I think the camera will become attached to my hand. This is going to be fun! I think.

DE80q · **Joined:** Fri Oct 14, 2011 4:56 pm **Posts:** 4611

I have a question for you guys. Has anyone run a light weaight fly wheele on an mc1 while still running cis? cant really find much info on this. Thanks in advance.

Quick updat on progress, Im pulling the drive train from 5k this weekend, weather permitting. I will post pics soon
