Thought I would add a few of the most common ECU pinouts and wiring diagrams, as I've managed to get a PDF writer working as well as a copy of Autodata. Unfortunately due to the file limits it's one per post. So lets start with the 306 S16, Bosch Motronic MP3.2. 306 XU10J4 wiring diagram.pdf

Yes that's right. Essentially a total novice with high performance petrol engine building attempting a full build. What could possibly go wrong!!! Anyway! The last few weeks have been fantastic for both me and the 405 really. Today I picked up the next round of parts for it for 2019. Being as I can insure it in January the plan is to build a second engine for a later date. And this is it. What I've got so far is 1 complete s16 engine with a knackered water pump that I bought for 80 euro. a xu10j4 iron block from an s16 that has been bored, decked and honed to 86.5mm 1 mi16 cylinder head with unknown regrinds. 1 damaged Gti6 head that I may or may not knick the valve guides out of for the mi16 head Kent cam pulleys Wossner 12.5:1 high compression pistons Pts sump baffle Pug racing 4 branch exhaust manifold Jenvey 48s Spoox aluminium crank pulley(ordered) Obviously I'm missing valves, valve springs, lifters, rockers, conrods and a crank to name but a few. How ever the complete s16 engine can donate what's needed provided its in good condition. Once I get a chance to measure the cams it should help me figure out what lift they are Valve wise I want to go bigger 36.25mm intake and standard exhaust. But in all honesty I think I will leave this idea for a later big valve lairy 290 degree head. For the moment I'm think 1 piece stainless valves of standard size. Crank shaft leaves me a few options. Stay standard, go with a 88mm Hdi crank or an xud11 92mm crank. 88mm Hdi sounds like the best option to me here as they are easy come by and forged. Conrod wise I'd think pec forged rods might suit my application and keeping cost in mind. But if anyone has any suggestions for better quality rods in a similar price range. New or used I'm open to that. Hoping to make a start at preparing the head tomorrow with a mild port and polish just to tidy it up. I may even hand polish the outer casting to 2500grit no performance gains obviously but it will look the the job. Might give the block the same treatment. Since this is my first major engine build any advice is hugely appreciated, what's best practice, what tools to use What fasteners are best used and where to get them. What gaskets and seals should I use Has anyone got a service manual for an xu10j4, xu10j4 and a dw10(for crank specs)

hello i've bought a car last year with multiple problems like overheating, water inside the engine oil and no engine oil pressure... somehow i manage to solved the 1st 2 problems...but the last problem puzzled me...no engine oil pressure...(only 2 Bar on the gauge). for the last problem, i've changed an oil pump, eng. oil water cooler & a pressure switch...but to no avail.. i figured out maybe the engine has gone an overhaul before..that the crankshaft spacer might have been wrongly placed which make the oil pump gear to slip hence giving so little pressure. i would be appreciate if someone out the can point out to me the correct position of the spacer on the crankshaft...outside the oil seal plate or inside?? please advise.... thanks

Hello everybody, Geoff Clements (jorg) is offering a Stage one PeterT inlet cam for a S16 engine... But it's missing the injection timing tab... Since i have a 205 running a standard citroen ZX 16V engine (similar to the 306/405 ones) i would like to upgrade it to take this cam (should be a straight fit) Can the tab be exchanged between cams? How to set the 'timing' / 'position' to the tab? Can this be done by someone with some experience of rebuilding engines? (I've done a rebuild of a S16 head and a complete TU5J2 engine) Would like to give this some more power: > i know the 'dip' shouldn't be there, but this has been overcome as i later discovered the valves on the ACAV system were not closing completely as the rod ends on the vacuum diaphragms were not set to the correct length
