veedubdude Posted January 25, 2008 Author Report Share Posted January 25, 2008 Well today saw the start of the major engine work! Ive managed to get everything ready for the block to come out tomorrow for when my mate arrives. The 8 gearbox to block bolts and then its onto the important part - stripping and rebuilding! So, this is how it went: With a bit of luck I'll have pictures of the engine built back up with a first coat of red paint tomorrow night!

Blackrat Posted January 26, 2008 Report Share Posted January 26, 2008 you gonna run the nitrous with the turbo ? nitrous and turbo go together real well, like hand in hand Quote Link to comment Share on other sites More sharing options...
veedubdude Posted January 26, 2008 Author Report Share Posted January 26, 2008 It depends what the engine maps too, I will run nitrous eventually, but I dont want to stress the internals out too much! Plus I'll be running the standard 75bhp gearbox for now....... Anyways, more pictures from today! Very productive day, and tonight the engine now has the new internals in! Need a few gaskets I forgot to get to fully build the engine back-up, but overall extremely pleased! Cheers! Quote Link to comment Share on other sites More sharing options...
veedubdude Posted January 27, 2008 Author Report Share Posted January 27, 2008 (edited) And another quick update - got the block masked and painted today! Still got a lot or prep work on the head and the gearbox before painting them so the whole things looks sweet, but here's how it went: (One thing I would say though, first I used spray-on high temperature paint from Halfords, after it turning out very dull I read the label and it turned out it was actually a matt finish! D'oh! So ended up painting the block by hand with some other high temperature engine stuff, and this has come out b-e-a-u-tiful, even if I say so myself ) Edited January 27, 2008 by veedubdude Quote Link to comment Share on other sites More sharing options...
Blackrat Posted January 28, 2008 Report Share Posted January 28, 2008 is that paint gonna stick ?couldnt you have found a brighter colour ? Quote Link to comment Share on other sites More sharing options...
veedubdude Posted January 28, 2008 Author Report Share Posted January 28, 2008 Yeah the paint should stick no probs! It seems extremely well stuck on!The photo's make it seem a lot brighter than it is, its a just plain shiny red! Quote Link to comment Share on other sites More sharing options...
veedub1955 Posted March 14, 2008 Report Share Posted March 14, 2008 Just a quick word of advice, dab a bit of engine oil on your con rod bolts before tighteningthe threads can bind and give a wrong torque reading and could be 2 loose, oiling them gets rid of this Quote Link to comment Share on other sites More sharing options...

veedubdude Posted April 1, 2008 Author Report Share Posted April 1, 2008 Small update: nothing is really getting done at the moment due to the last few weeks of uni eating up my time! However, I have had a bit of an idea about mapping today. After talking to stealth racing, Ill need an additional plug-in module to control the MAP sensor and prevent the engine going into limp mode... on top of that, mapping is going to be a nightmare - well, if it goes the same as the last 1.4 turbo they did!But talking to one of the chaps over on uk-mkivs awhile ago that has converted his 1.6 to a 4motion, the engine looms simply unplug and plug into the firewall/ECU for each engine... So, my plan is to lose the 1.4 loom, and run a 1.8 Turbo loom... along with ECU, and clocks... Which will also add a MAF sensor to the engine, and should prevent any problems, plus be a lot easier to map!Other plan for now is to run the engine Ive built up with some cams if I can get hold of them, whilst building a new engine up with forged internals, diesel crank, etc etc with a custom manifold for a KO4, instead of the originally planned KO3... Basically go the whole hog instead of half way! Quote Link to comment Share on other sites More sharing options...

veedubdude Posted April 3, 2008 Author Report Share Posted April 3, 2008 where you getting a diesel crank to fit ? Im not sure out of which engine, but I was specking to advanced autosport about internals etc. and he said the crank can be taken out of a diesel engine. If you're interested, talk to Erik there OLW - Im not buying any of the major parts yet, as when the golf is back on the road I need to look at my polo before I start getting the bigger turbo stuff finished - Just out of interest how much do you want for it, and you got any pics? lol Quote Link to comment Share on other sites More sharing options...

If you're interested, talk to Erik there He told me that also, I think it may have been the crank out of a N/A Diesal engine, but it was some time ago I have forgotten which engine it was.

Blackrat Posted April 3, 2008 Report Share Posted April 3, 2008 i remember looking at the diesel crank dimentions and thinking damn thats a perfect fit ......then the penny dropped ... the diesel crank is 3 cylinders .. duh so if you plan on welding on another journel i still dunno where you gonna get oneon the old skool vw engines that is possible , as the blocks are the same on the diesels Quote Link to comment Share on other sites More sharing options...

veedubdude Posted April 3, 2008 Author Report Share Posted April 3, 2008 (edited) Right, the AVY stroke is 86.9mm, so that puts the 1.7 SDi crank in the correct reagion. It gains the extra 0.1 litre with a slightly bigger bore by the looks of it.The 1.7 SDi is AKU engine code btw.Now the hunt is on to find one, to see if it actually fits.... lol Edited April 3, 2008 by veedubdude Quote Link to comment Share on other sites More sharing options...
Blackrat Posted April 3, 2008 Report Share Posted April 3, 2008 i cant be arsed to look for my catalogue , but when i looked at other lupo diesel engines none of them would fit .. but you deffo onto a winner if that crank fits !! get one !!

ArosaMike Posted April 5, 2008 Report Share Posted April 5, 2008 Will the big ends not be completely different? Diesel big end bearings have to be a lot bigger? Or were you planning on using diesel con rods too? Quote Link to comment Share on other sites More sharing options...
veedubdude Posted April 15, 2008 Author Report Share Posted April 15, 2008 Well, a bit of an update; I decided to get my arse into gear last week and get the engine back in for spring fest, running without the turbo, but with the nitrous up and running instead. Unfortunately for me I managed to make an amateur (read: stupid) mistake. To cut it down:Got everything back in... everything together, ready for the custom exhaust. Out of curiousity if it'd start I tried it; but it wouldnt start on just the 4-2 manifold, and after talking to a few garages it was agreed it was probably the backpressure; so I got the car on the transporter to MIJ performance for a full exhaust from 2 part mani back. After its done... nothing, just popping alot of flames... bit gutted by this point, but because the injectors had been swapped out for bigger lupo GTi ones, it was assumed the mixture was completely out, and hence wouldnt start. Went up there and swapped the old injectors back in... Still nothing, apart from popping alot less flames. They run the diagnostics and it comes back with a cam / crank sensor problem. They test the sensors but its not them, all readings appeared normal... They came to the conclusion that I'd managed to put the belt on 180 out, hence the flames etc. I couldn't understand how, as I knew all the markings lined up... That's when I suddenly realised I hadnt checked the pulley notches where the same on both cranks... Wasnt happy at such a stupid mistake so got the car home and inspected the timing belt... Physically measured TDC with a nice long screwdriver... everything spot on. Now by this time Im head scratching, and pretty gutted its still not starting... So since Id done the engine work myself, I start to check all the vitals needed for the engine to start... fuel/air, compression, spark, timing. Plugs getting wet, and the compression was 185 - 190 on every cylinder. So its something to do with the spark, now with my engine running seperate coils I started to look at where the information for the spark timing was coming from... the cam / crank sensor. And thats when it hit me. In the minor 'rush' Id had the weekend before spring fest to get the engine bolted back in while a mate was here to help me, Id forgotten to set the oil seal/crank sensor wheel to the correct point to correlate with TDC. So the ECU is 'seeing' the cam/crank sensor is completely out of sequence and not letting it start; cutting fuel / spark. Looked through the sensor hole while turning the engine, and the 'missing' tooth is sitting about 270 around the engine sequence. Which explains the flame popping, as it was igniting as it came up pushing the fuel out of the exhaust... What an idiot, when I realised Sunday evening I was absolutely kicking myself! Ah well, you live/learn and I wont be doing that again! So the engine's got to come back out so I can line the crank sensor wheel up, and then #fingers crossed# she should be up and running, and ready to be remapped. This is more for my own sake as I keep losing the sheet Ive written down with the spec on, but she'll be running: Lupo GTi inlet mani, TB, injectors and fuel rail. Lupo GTi, balanced, lightened and knife edged crank. Original 1.4 flywheel, lighter than 1.6, and will be balanced. Lupo GTi rods and pistons. ARP big end bolts. Stainless steel 4-2 raceland manifold, with full stainless steel exhaust and bolt in/out decat/sports cat. Full custom remap. Blocked EGR valve. Approx. 30 shot of nitrous to start. Im hoping for 130 after the remap, 160 with the nitrous. Seen as Ive got to take everything out again, Im also going to invest in the gearbox fix kit, and a new sports clutch. I may also invest in some new cams seen as Im going to be running this engine N/A for now, but havent decided whether to or not yet! If I do Ill be looking for 150 without the nitrous after a full map! Pics to follow... Quote Link to comment Share on other sites More sharing options...
veedubdude Posted June 10, 2008 Author Report Share Posted June 10, 2008 Thought Id update this thread again - got the engine out again, and rebuilt it onto the new block! Now running cast iron (from a lupo GTi) instead of the standard aluminium! Also got some new cams in her from the lupo sport 1.4 100 bhp engine, so Im looking forward to seeing how these go compared to the older cams! Anyway, waiting for the cam carrier sealant to set then I can time her up, and #hopefully# get her back in tonight! Alot more detailing work to be done, but this as she stands at the moment: Quote Link to comment Share on other sites More sharing options...
dubsy Posted June 10, 2008 Report Share Posted June 10, 2008 looking good hope the cams run ok for you should see some improvement. I think there is about 4 lupos out there now running with different bits of my sport engine in them its great! Quote Link to comment Share on other sites More sharing options...
