I'm gonna share some pictures and info about how to do it. Few years ago I've bought 3.2l bottom end (BDB) with only 3k miles on it (comes from Audi A3 test car). Yesterday I found 3.6l BLV head from 2010 Passat (30k miles). The idea is simple - R32 with big port 3.6l FSI head. FSI head bolts right on the non FSI block. However there are some oil ports which has to be welded shut. I'm not gonna use the FSI injection system so the injectors will be replaced with ss adapters to block the holes. My idea is to fabricate an adapter plate for standard injectors and run the engine using ME7.1.1 ECU (either MK4 or MK5). Anyway the adapter plate for standard injectors is the most important part on this project because I'd like to use it on supercharged 3.6l fsi engine to add fuel.
good that it fits, any reason why you just wouldn't use the full 3.6 engine though, 3.6 has to be better than the 3.2?
...I could say: because I can, but there is more than that. I'm very curious about the gain from big port head. Complete 3.2l bottom end was only 200 Complete 3.6l head was 160 All I have to buy is the 3.2 head gasket, 3.2l head bolts, 3.6l upper chain, I have complete 3.2l wiring and ECU ohh and R32 injectors (because I supercharged MK4 R32 last summer) ...I have CNC mill too so fabricating parts /adapters is easy I love MK2 Golf At the moment I'm focused on the tech aspect of the engine. Once it's done I'll either find a customer for it or a MK2 chassis to install the engine because I's gonna take a week to tune the ME7.1.1 ECU FSI has different cam adjusters and those maps has to be properly tuned
I have this: It comes from 3.6l Skoda SuperB, same part number as Passat R36 intake mani - without variable-lenght system.
Nice will be keeping a eye on this to see how you get on Is the mk5 and mk4 ecu going to work with the new head or you have something up your sleeve
The cam adjustment system is different on 3.6l because it can make up to 42* overlap. That is why 3.6l FSI has no EGR And I'll rather use MK5 ECU because the runner length compensation is done by cams (like in 3.6). I'm sure it will work, but as I said before it may take some time to tune. Cam position sensors on 3.2l and 3.6l head are the same (030907601E). I'm quite sure it will work fine.
The mk5 engine has more overlap than the mk4 on the cam adjustment doesn't it I've been told I'll have problems with this when I fit the mk4 ECU in my 4motion It as a mk5 bub engine I guess I'll soon find out I have all the mk5 part s other than a ECU So if it comes to it I can go down that route
Yes it does. Cam adjusters are different. I've been there already Last year I was told to wire R32 engine from Audi in MK2 Golf. I had no idea about engine code so I took ME7.1.1 ECU from my workshop and did the job. I got some timing sync fault codes and later (after 2 days of research) I realized that I'm running Audi TT 8N (like MK4) engine on Audi A3 8P ECU. I replaced camshafts with adjusters (from MK5 BUB) and all fault codes were gone.
I thought 3.6 was different V angle to 3.2. Also could be worth checking the cc volume of the head vs stock if it's FSI.
3.6 is 10.6* (non FSI VR6 - 15*) but it does not matter. The cc volume is in fact different but I'm gonna take care of it.
So does the head gasket all still match up ? Look forward to seeing this progress - cant believe you found the block and head so cheap! I hope this is getting boosted
Yes the R32 head gaskets is a perfect match. I guess I was lucky It won't be boosted. The MK2 I've bought today is only FWD OK. Progress: all extra oil return lines were welded shut and the head is almost ready for install ...I could not resist and I bought myself (today) '91 MK2 Golf 1.8 GT for 200 The dealer claim the engine is dead because the oil warning light is always on. Yeah, right, it is really hard to kill 1.8l RP engine ... the connector on the sensor was lose. Except for that it runs perfect. OK, I got MFA, power steering and rear disc brakes
I'm about to shut the FSI injector holes. Some parts has arrived: - R32 head gasket - R32 head bolts - 3.6l head chain guides - 3.6l upper chain Still waiting for 3.2l ECU and wiring
Subscribed! I like the manifold - The runners looked stepped to provide resonance at higher RPM or am I wrong? I'm thinking of investigating (when I get my next pay rise) whether I can easily put a 3.6 bottom end in the Bora (it has a MK4 3.2 BFH running on an ME7.1.1 ECU) - Is this likely to be relatively straightforward conversion?
They (VW) changed the design - modified duct geometry and kept high torque and power output on the 3.6l fsi engine. However there is Touareg variable intake manifold that works on the principle of resonance charging and provides highest torque numbers more info you can find in SSP 360. You can swap the entire 3.6l engine incl. ECU but swaping the bottom end only ... how you plan to weld a cast iron block
