Hi i would like to show my ITB work from start to finish.. enjoy I cut my original GTi inlet manifold Testing angle I made vacum colector for Map and steper motor... to work with oem Ecui instal saab 2.3 turbo injectors (370ccm)

I am putting together an engine (XU10 RGX with 1.9 Mi16 cylinder head) and need a solution to fit the cylinder head to the block using studs. What I have is a set of 'custom head studs' 145 mm in length and a set of Honda F20C ARP studs (170-ish mm in length) which also happen to be M12x1.5. If I use the 145mm ones I will not have enough thread above the waterpump, the washer + nut is sticking out above the stud, this is when no head bolt spacer is used. If I use the spacers on the 9 other ones I will have the same problem (nut sticks out above stud, about 3 or 4mm). If I use the ARP Honda studs, above the waterpump I would have enough thread for the nut to hold but only if I use a headbolt spacer as the stud is too long, for the 9 other ones I would need double spacers because the nut would just fall into a place without thread (socket will be too short also). A specialist told me to always use the head bolt spacers to prevent damage to the cylinder head (ARP washer is not enough to spread the load?). I was wondering if it is safe to put double spacers or if a set exists where I can use 1 spacer per bore and not have studs too long or too short. Does anyone know a way to safely do this, maybe with the parts I already have? I have looked on the forum before and someone mentioned the 'AU6.195-2LB' single stud but I cannot find this part anywhere and I am not sure which stud set was used. Hope someone can help me, I already spent a lot of money on parts and overhaul (and time waiting for a 16v turbo manifold which took over a year to make)

Hi everyone! Some time lurker, recently registered and first time poster here. In early February I bought a -95 405 GTX "style" with the XU10J2C engine in it. Car is driven 160k km and in otherwise good condition. The previous owner said the headgasket needed replacing and exhaust needed welding. So, I've replaced the headgasket which was definetly needed and exhaust is under construction. Today was the first time we test started it and noticed it's firing on only 3 cylinders, 1,2 and 4 (counted from the left). We thought no big deal, we have dealt with similar issues on motorbikes and old volvos before. First we took out the spark plug and turned the engine to see if it sparked, it did. Second we moved over the injector from cylinder 4 to cylinder 3 and cylinder 4 kept working while cylinder 3 stayed dead. We then did a compresison test on cylinder 3 and got 9:1 compression ratio. We checked continuity on the cable to injector 3 and there was continuity with 0,004 ohm compared to 0,005 on injector 4. Voltage to both injector 4 and injector 3 was tested and was all over the place but pretty much in the same range for both cylinders. When spraying starter spray in the throttle body it starts running on all 4 cylinders The injector cables to no.3 are damaged where they popp up from the center of the intake manifold but we assume (for now) that the damage isn't of importance as continuity and voltages are similar. I read in another thread something about some relays that might need changing or perhaps even the control unit itself. Suggestions and where can I find the control unit for the injection system? P.s. I have a wrecked 405 with a XU7JP (LFZ) engine which I can use for parts. Thank you in advance. (pic semi related, it's a XU10J2C)
