kpr Posted August 15, 2013 Share Posted August 15, 2013 ok, the stock setup. 1 line comes from turbo - goes to actuator 2nd port on the actuator - this goes to the boost solenoid via those metal pipes out of the boost solenoid - goes to the plastic air intake pipe basically that whole setup above is junk if you mess with it. so flag that whole setup. run pipe from inlet manifold or intercooler pipe as i said. directly to the actuator. block the 2nd port on the actuator if it has one ( i take it you have the adjustable one installed). you can adjust the arm on the actuator to adjust boost, shorter = more boost . longer = less Quote Link to comment Share on other sites More sharing options...
ep82-toy-let Posted August 15, 2013 Author Share Posted August 15, 2013 I never put the other actuator on, as some one told me it wasn't nessesary? I cant see a second port on the factory actuator. so ill just get a nipple welded to the intercooler pipe and see how I go. Quote Link to comment Share on other sites More sharing options...
kpr Posted August 15, 2013 Share Posted August 15, 2013 ah yeh, try that to start with then. if that doesn't work i'd switch to the new actuator. factory ones are known for being weak. the factory actuator definitely has a 2nd port. thats how the hi low works.

ep82-toy-let Posted August 15, 2013 Author Share Posted August 15, 2013 ok sweet, will give it a try, if not ill fit the new actuator, the new one only has one port. cheers for your help...... if all else fails, ill revert back to top mount intercooler lol, atleast I know that setup was working.

ep82-toy-let Posted August 16, 2013 Author Share Posted August 16, 2013 had a think about it, and have decided to bite the bullet and just buy a electronic boost controller. easier Quote Link to comment Share on other sites More sharing options...

mjrstar Posted August 16, 2013 Share Posted August 16, 2013 ok, you can adjust the arm on the actuator to adjust boost, shorter = more boost . longer = less Technically yes...... I'm not trying to be a pain in the arse on this but given the actuator stroke of probably 8-10mm adding preload really isn't a great way to raise and lower boost, and depending on flow rates and valve flapper size you can very quickly end up not being able to effectively control boost... you could very quickly lose 1/3 or more of effective stroke and end up boost spiking / creeping.. Anyway personally i'd avoid any more preload than just enough to firmly seat the flapper.. to be clear I am all for cranking boost levels up - and if your hardware is up to the task even a simple boost bleed tap can work pretty well...

ep82-toy-let Posted August 16, 2013 Author Share Posted August 16, 2013 well, I just braved the pouring rain to have one more stab at it, and nows the time were the "face palm" would suit haha, had it on the rong hose, it wasn't the correct one for the turbo pressure, I was lookimg around and tucked away down the back of the manifold was a small black hose going into a small black box, rubbed the dust off the top of it, and guess what it said? "turbo pressure" lol, so tee'dit into there, havnt gone 4 a boost yet as theres a car in my way but Im hopefull! fingers crossed. there was a black restrictor thing on the pressure line also, I left it on but would it be better to take it out?

kpr Posted August 16, 2013 Share Posted August 16, 2013 thats the map sensor, the one i said not to plumb it into. change it back before you drive it. as you will likely lean out if the stock boost control starts to bleed air out Quote Link to comment Share on other sites More sharing options...

ep82-toy-let Posted August 16, 2013 Author Share Posted August 16, 2013 only reason I did that is I watched a vid on you tube, mighty mods, they did a starlet and used the same pipe they tee,d into it to get a pressure signal for a electronic boost controller Quote Link to comment Share on other sites More sharing options...
kpr Posted August 16, 2013 Share Posted August 16, 2013 that is different though. would be for closed loop control or gauge readout. how you had it boost solenoid would be bleeding air off the map signal. map sensor directly tells the ecu how much manifold pressure /boost engine is seeing and supplies the correct amount of fuel for example you have: 6psi actuator boost solenoid bleeds off 4psi boost from boost signal line, once manifold pressure gets to 10psi, actuator sees 6psi and opens as normal. map sensor also sees 6psi so actual boost engines seeing is now 10psi. but you are only getting fuel for 6psi = lean air fuel ratio Quote Link to comment Share on other sites More sharing options...

eke_zetec_RWD Posted August 17, 2013 Share Posted August 17, 2013 Take it to a shop and if they can't fix it all in a hour then there's other shit wrong. 1 hour of professional help will be cheaper than a melted motor. Quote Link to comment Share on other sites More sharing options...

flyingbrick Posted August 18, 2013 Share Posted August 18, 2013 Nah fuck that man. You rule for giving it a go- researching and learning. We all started with no knowledge. You need to find someone who will show you how it works, point out any issues and get it going as good as it can. Surely someone here on OS can oblige?
