SiCaln Posted July 29, 2011 Author Posted July 29, 2011 Dad sorted the loom yesterday, so got in plugged it into the car and went to start it and it cranked but wouldn't fire, didn't have the HKS ecu connected though so will try again sunday, if not, he thinks he knows which two wires are the wrong way roundSo hopefully car will be firing and ready for mapping, well once I've done a compression test that is...

Sparky Posted July 29, 2011 Posted July 29, 2011 Yay!My care wouldnt fire because there was no base map on my ECU, could be your problem if it hasnt had a map before? Quote
Jozinobi Posted July 29, 2011 Posted July 29, 2011 Nearly there Sime with the ecu side of things.Hyaku Joz Quote
SiCaln Posted August 1, 2011 Author Posted August 1, 2011 Refitted the loom with the ecu attached, it fired first time then stalled - so I'm thinking it's what you just suggested Sparky very happy to say the leastGot a mates comp tester at home just want to do that first before mapping because I still get the blue smoke after a run Quote
Nanglebadger Posted August 1, 2011 Posted August 1, 2011 glad to hear she's firing for you man!your dad must be a fairly handy man with the old wiring! kudos to him!Phil. Quote
shorty Posted August 7, 2011 Posted August 7, 2011 Coming n nice si, when you say sps cams do you mean the speedvison as i didnt think dane ever made cams?? Cant wait to see what figures she pulls. I know we have had a fair few convos about cams so glad your happy with the pull i love my speedvision cams tbh!! Espesialy coupled with cruise springs Quote
SiCaln Posted August 8, 2011 Author Posted August 8, 2011 yea sorry, im silly i do mean speedvision, yea not long now i hope Quote
SiCaln Posted August 11, 2011 Author Posted August 11, 2011 Did a compression test on the car yesterday, all 4 cylinders 130psi - is this a bit low?!Also noticed car has too much oil, maybe this could contribute to the blue smoke Quote
Socks Posted August 11, 2011 Posted August 11, 2011 Did a compression test on the car yesterday, all 4 cylinders 130psi - is this a bit low?!Also noticed car has too much oil, maybe this could contribute to the blue smokedid you run the test when the engine was cold or at operating temps?if it was cold, then no thats not a low result...did you also have the throttle wide open when u performed the test?Your looking for consistency with a compression test mainly... if there all 130 dead on your a lucky man! Quote
SiCaln Posted August 11, 2011 Author Posted August 11, 2011 I had driven for 5mins before doing it, then did it full open for 10 secs - was 130 132 132 130I have also read Speedvision cams do drop compression rates too, spose wasnt that hot running Quote
WallaceGlanza Posted August 11, 2011 Posted August 11, 2011 It is fairly low, 160-180 is around the standard compression. Cams and headgasket may have lowered it? Quote
Socks Posted August 11, 2011 Posted August 11, 2011 headgasket would lower the compression ratio... but wouldnt lower the compression itself, so its still low...id retest si tbh! wen its fully upto temp...might be a leaky valve seat or summink cus it is low!? how much milage is on the bottom end? Quote

If you increase the volume of the cylinder then you will reduce the pressure: P=F/A Quote
SiCaln Posted August 11, 2011 Author Posted August 11, 2011 mileage wise id say its bout 8k miles not much, can certainly re-do it after a long drive Quote
whiteglanzav Posted August 11, 2011 Posted August 11, 2011 If you increase the volume of the cylinder then you will reduce the pressure: P=F/Ayes correct Quote
Socks Posted August 11, 2011 Posted August 11, 2011 but arent you effectivly pumping up a gauge? wouldnt it be same psi if u spaced it 1mm or 10mm?if im wrong fair doo's learn summink new every day. but if uve lowered your compression then 130psi wont be that bad! Quote
Corey Posted August 13, 2011 Posted August 13, 2011 Those cams would definitely lower your compression dude I looked into it before when I had a set also what size head gasket is on it and are you 100% the cams are dialed in? I remember doing a compression test on an engine with 2mm gasket and dished pistons it was 130psi across all 4 runs perfect bomb proof engine really its still running with no problems years later. Too much oil might be pushing some through the turbo seals is there an increase in pressure? Cool project dude nice work Quote
Socks Posted August 13, 2011 Posted August 13, 2011 as i said before... your looking for consistency! so if there all nearly the same your laughing! Quote
SiCaln Posted August 15, 2011 Author Posted August 15, 2011 I realised I had way too much oil like 15mm above the full line! So took some out and wanna check it after its been sitting all day today may need to take some more out, still some blue smoke, but not as dense thankfully - may need turbo oil seals replaced still tho if it proceeds Quote
SiCaln Posted August 26, 2011 Author Posted August 26, 2011 Lot less smoke now, could just need a long run to clear the pipesOne step forward two steps back tho lol, bought a pressure washer got the car all foamy, then when I washed it off with the Nilfisk it took a large section of paint off from under the rear driver's window, luckily just one layer, but that whole side needs work anyway so that will be done after JAE Quote
Nanglebadger Posted August 26, 2011 Posted August 26, 2011 sometimes i reckon if it wasnt for bad luck you'd have no luck at all man!!!!put me right off pressure washers that has!Phil. Quote
SiCaln Posted August 26, 2011 Author Posted August 26, 2011 did a lovely job on the arches lol, tbf tho the paint is 13 years old and it is that bit under the window where all the shit gathers n prob rots the top coat, not too worried tbh it'll get fixed along with the rusty arch and the scratched boot lid area - all that same panel thankfully Quote
SiCaln Posted August 30, 2011 Author Posted August 30, 2011 Things have progressed, changed the 13 year old track rod ends today and have changed to the white wheels, tomorrow tracking will be done and putting the JAM rear bumper back on and this time i'm gna put bumper supports on the bottom of itNot a bad week so far lol Quote
Nanglebadger Posted August 30, 2011 Posted August 30, 2011 sounds good buddy! tis the fine touches that make this ride so pimping!Phil. Quote
