i also thought about carb cleaner, will give that a bash also...cheers :)

Its brand new oil and filter thats in at the mo....so cant be that. I'll give the thermostat a try....and will look out for a 13 row mocal or something. Anybody else any pointers towards the hesitancy? injectors? anything else? Just seems to splutter a bit in low revs and when its past a certain point its perfectly fine

Ahh....thing is my last engines bottom end went due to oil starvation or pressure and was about 124....just abit worried o be honest. Is it worth getting the mocal oil cooler to pt mind at ease?? And any idea on the hesitancy??

Hi guys needing a little help.....got another rado 2.9 engine fitted! and its runnign quite nicely, getting a few wee teething probs with it though! Dont think anything too serious but defo needs sorted. First off, does anyone know what VR's oil temp should roughly run at?? I have a feeling i am sitting a bit high! Normal town driving isnt TOO bad! Sits around the 110 degree mark, but i have been keepiung the heaters up full blast!!! But on duellers and motorwas etc, it seems to creep up quite high! 70mph will sit around 116 degrees and around the 80 mark was on 118 and at one point 120...i didnt go anything over that and just kept at 70. I was too scared to go faster than 80 because i just kept thinking the oil temp would keeping creeping higher and higher. And that was the prob with my first rado engine when the bottom end went So what do we think here? duff oil cooler? is a Mocal required?? I dont want to have to go down the route of paying the prices for a mocal! Another wee prob is that it feels quite hesitant in low revs and on half throttle.....sort of stutters a bit. Could that be fuelling issues? remap required?? Cheers guys, phil

Ok i'll pass that onto peter. Thanks guys i'll see what he throws up...fingers crossed! :) We put it on vag com and couldnt get a connection for some reason :S Oh and james what you reckon to this??? http://www.edition38.com/forums/index.p ... 30596&st=0 Comment 19 and 20?? im very sure with the obd2 you need to use the full loom and ecu as well to make this work.they have different versions of software in the ecus.later ones run an updated motronic system.if its a late obd2 they only work with one ecu number and that ends with the numbers 256 and has no letters after it.these engines were produced from 96 onwards. the posistion of the sensors are the same thats why both cams i.e sets from a 2.9 will fit a 2.8 only difference there is on the end of the cam gear it has a drive gear for the dissy and on the coilpack its a magnet that is picked up by the CPS very sure the number you want is 021 906 256 and no letters at the end for the ecu.ecu software systems Look at the golf vr6 95 onwards its different to the corrado.hope this helps Thats what a lad is saying on ed38? whats the story behind that? Cheers buddy, phil

Ok thats fine then......well the original loom and ecu are being used, but the donar sensors are being used at the moment as they have not been changed on the 2.8 to the 2.9. The crank sensor is the oriniginal sensor of the donar 2.8 engine....NOT the original sensor to the 2.9 rado engine. yeh i dont reckon its the engine either....definitely electrical/sensor based. If the sensors are incorrect, will this show up on vag-com? And basically prove the problem?

God, i am getting a conflicting view on ed38..... http://www.edition38.com/forums/index.p ... try1106311 This lad reckons since i am using a late 98 obd2 engine that i need a late 98 ecu to match, as the ecu numbers only correspond to certain engines :? but i am more entitled to think it must be more straight forward than that! You reckon swapping over the 2.9 parts and basically just using the 2.8 block and head that this will solve it? Cams and sensors? anything else?? Sorry if your getting frustrated :? I'm just a 3rd party trying to pass on info :( frustrating myself also! Thanks, phil

Aw Great!!! So you cant use the obd2 engine with the original obd1 gear! Brilliant :( I cant be bothered at the moment running obd2 cos it means having to gather parts and shortening and lenthgthening the loom etc etc! So is this a case of fully converting over to obd2, or finding another corrado engine (or rebuild mines) and sticking with standard. I just dont understand what massive differences there can be between the actual engines of the 2.8 and 2.9? At the moment, the obd2 2.8 engine has its original cams and sensors etc....do i need to replace these from the 2.9 obd1 engine? Surely there cant be a massive difference between the engines and its just a little prob holding it back?

:lol: :lol: :lol: So you do reckon its the sensors....ok tell me what needs rectified then. Is it the fact it is the obd2 block, head and sensors? Do the senors differ on the 2.8 and the 2.9? Just tell me what you'd do and i'd pass that on :) Thanks buddy :)

Found out, my corrado was coilpack, along with the golf engine gone in, so doesnt look like that. When the guy is adjusting the timing, he locked it half a tooth out and it kicks into action but obviously wont run properly......when timing is spot on, it wont even fire up.....just turns over and wants to! Tried various throttle positions with no added success. Compression testing done....all was fine and within limits. What we are reckoning is that maybe, due to using a 2.9 obd1 ecu with the 2.8 obd2 engine that the cam sensors are in a slightly different position to what they are on the 2.9? The ecu is getting a signal but since the positioning of the sensor is different, it wont kick into action. So now what? Whats best? A change of ECU to the golf 2.8? alter the cam sensor postion? What you guys reckon??

Thanks buddy great help once again, i'll pass this onto to see if this has all been checked and if any of it is of use....i dont have a pic of the doner engine, but this is my one...well the 2.9 Can try get you a pic of the donor engine mate

Mate, i'm not entirely sure what set-up it is.....sorry if this sounds thick, but between the differing obd1 & obd2 set ups, is one dizzy and the other coil?? If so, what do i need to run to be compatible with the 2.8 engine but still run with the original obd1 rado 2.9 gear? Cheers for the reply again dude, this is all stuff i can take to him to hopefully get it moved on a bit. Someone over on Ed38 said that the timing sensors are different between the coil and dizzy? could this be having an effect bud?

At last, a proper answer!! The head gasket was done, apart from that thats about it apart from the engine being apart. Oh and new 2.8 chains were put in. The engine came from storm developments, so i was strongly hoping they would be a pretty reliable source. He just wanted to check the timing to eliminate, but it was checked and at the correct setting. The mechanic specialises in VW's....not VR's, but VW's in general and he really seems to know his stuff. Yeh, obviously not coil if even a timing tweak starts it. Fault codes, will get in touch with him to see if he has Vag-com to check, its hard keeping regular contact due to me bein offshore alot. I'm fairly certain the covers were taken off the 2.9 and put onto the 2.8, as for cams, fairly certain these werent swapped over, original 2.8 cams are being used. I'm sure of it!

Hi guys, right....well just when i got my corrado, he bottom end went on it so i immediately set about lookin for a replacement to put in while this one was being rebuilt. Thing is, i was led to believe the OBD2 engine would drop straight in and run perfectly fine, i found a good deal where i got a 2.8 VR engine from a 98 golf with only 48k on it. So i went for it with the low mileage being peice of mind! The guy putting the engine in has it in but when the engines timing is at TDC it will fail to start, but when the timing is advanced, it kicks into action no bother at all, but obviously has a complete lack of power due to the timing being out. So he reckons its either compression of the pistons or something to do with the ECU...any you guys got any theories cos its really starting to get quite depressing! Feel like i should just go and shell out for another corrado engine instead! Really wish i had stuck to just going for the 2.9!! Is there any way, that its not reading from the ECU? Compression? I'm not very engine adept, someone mentioned it could be the coil? Any ideas?? And if anyone has a good running 2.9 VR engine and would like to swap for a 48k 2.8, get in touch. Cheers, phil BTW, its all original 2.9 peices, all OBD1 apart from the fact its a 2.8 engine

Nice one lads, think i am going to go along the lines of Junkies set up. The sub in the middle, but will be angled up the way and then an amp either side, all on custom plynths ets so it flows together :)

No thats perfect guys, keep them coming! Helps me get all those ideas rolling in my head :D

The corrado deserves to be rear wheel :D

Alright lads! Thought i would stick this in here as i think it will get the most recognition to be honest. Does any one have any decent pics of nice, subtle installs into the boot of a rad? I'v got all my gear and i'm pretty stumped as to how i want the install to look :S Any help would be awesome guys :D

Whats the best oil to use in a VR6 mate?

I dont liek it :( Looks far too big imo...looks ok in the first pic, but the 2nd one just looks far too empasized. All imo of course :) ah just noticed on ed38, you were just tryin them on off the mk4

right since this engine is just a temp thing i am going to leave it OBD1 for simplicity. The 2.9 will be getting rebuilt and put back in anyway, so its not a major deal. Aslong as the power is still roughly similar. I'v hear that the later VR6 engines are still stated at 174bhp but tend to push out ALOT more, nearer the 200bhp mark :D

And so if i am to go OBD2, what is everything that i will need? Loom, ECU, MAF, lambda, and throttlebody? Anything else and will that all drop straight in? Only thing is, as standard these engines are meant to produce 174bhp...not so keen on that considering the 2.9 pulls 190bhp as standard! What parts would i be best using from the 2.9 to use on the 2.8? Obviously the inlet manifold and the injector rail? What else? @ Bigpants baby, i might take you up on that....what mileage is the engine?

Fuck sake i am uber confused now!!!!! So if i was to use an OBD2 ECU, surely i would need the OBD2 loom to hook on to that ECU or the connectors wont hook up? I'm not massively bothered about future mods etc because the 2.9 is going to get rebuilt and then put back in. Aslong as i will still see my 190+bhp, with the throttle body and inlet manifold from tthe 2.9? sorry to be a complete noob,but whats the MAF?

Yeh thats right buddy Not got any of my own photos of the rado really yet since the engine went on me the day i got it :( Will get up in a couple of weeks while the new engine is being put in while i am offshore! Its the hardest thing in the world buying a new car like this and not being able to drive it :(

Speaking to storm, they are leading me to bleieve i can just change the injector rail, inlet manifold and throttle body and it'll drop straight in and hook up to my original loom? This true? The engine is from a 98 mk3 golf
