Getting car to run

[burnout 180]

Alright i have my turbo in but now their is a problem. When i pass 5k in second gear or any other gear but first. when boost begins to come on strong something makes a pop sound and it is as if i let off of the gas and i go no where at all. Acceleration completely stops. anyone have an idea of what is causing this.

Also what are the lines that are connected to the stock turbo used for? All of these lines come off of a square gray device with i think three plugs connected to it. i believe that this is the distributor. I thought that these were vacuum lines but i feel no vacuum coming from them.

are u sure your hotpipe isnt popping off? check to see that its tight and that u dont have any small boost leaks.

a distributor has nothing to do with the turbo. distributors feed spark to the motor and are completely independent of the turbo. not too familiar with CAs but i know it wouldnt be a distributor. are you sure it isnt an oil pickup or anything for the turbo?

[jt15833]

yea just check all vacuum lines and even though this wouldnt stop acceleration completly exhaust leaks make nasty noises and can really hinder performance on turbo cars. not 100% sure what you are talking about but in automotive terms the distributor is an ignition device used for distributing spark, us with ca's are lucky enough to have coil on plug however and not deal with distributors or wires.

the vaccuum line for the turbo comes off a grey box with 3 lines coming out? sounds like a boost controller, if you dont have the control module for it, and youre running about stock, then trace those lines, see where they go. Then run a new line from the manifold to the wastegate actuator (or if you have a stock turbo, just run a hose from that nipple on the compressor to the wastegate actuator)

remove extra vaccuum lines and plug them to start troubleshooting

This is what i was talking about. What is this device and what are these lines for? Where are they supposed to connect to?

I'm trying to get my car running on my new setup.

either something factory or aftermarket, either way its not needed. vacuum is real simple on this motor, you can find nice diagrams if you search the CA board,but basically, all you need to hook up is the

fpr / butterfly - both of these should be t'd off of the smaller nipple on the back of the manifold (facing firewall)

wastegate - nipple on turbo

brakebooster - use the larger nipple, also located on the back of the intake manifold facing the firewall

boost gauge (optional) - use the nipple right behind throttle body pointing towards the passenger ( on lhd car) side fender.

That' s the factory boost cut solenoid.

Unhook it. Most of us dont use the solenoid at all.

[silvia_ca18det]

just run vacum line from your TB to your wastegate! dont need to go to that solenoid! its useless and makes engine bay look ugly

[jt15833]

tb to wastegate is kind of innacurate, id go closest source to the turbo which is the actual nipple on the turbo. if you had a decent leak causing your tb to see say, 12 psi while the turbo was actually working at 14 psi that may be harmful in the long run.

[burnout 180]

I was going to use this vacuum in the back of the TB for my wastegate, MBC and BOV is that alright?



Also I have the vacuum with the MBC on it connected to the nipple on the side of the wastegate however i still don't know where i'm suposed to connect the nipple on the top of the wastegate to.



P.S My turbo doesn't have a nipple on it.

[jt15833]

yea if your turbo doesn't have the nipple you can use the throttle body one. as long as there all hooked up and theres no leaks in your intake system, there wont be a noticable difference in performance

[burnout 180]

i still don't have my vacuums right. so i took some pictures and if you could tell me the which vacuum i should hook the following up to:

Top wastegate nippleside wastegate nippleManual boost controllerBlow off valveboost gauge.

Here are the pictures i numbered the vacuums so you can just refer to the number.First this is on the back of the intake manifold.This is number 2 again on the back of the intake manifold.This is on the side of intake manifold near throttle.Number 5 is right below throttle body.

Please help me i just want to get my car running again.

Scroll a few posts down and you will find a vacuum diagram. I find this to be the simplest diagram to understand.

[burnout 180]

I couldn't get my boost set at 10 psi with my MBC so i connected it directly to the vacuums without the MBC and boost is now going to 12psi.

This means that my wastegate has a 12psi spring in it right?

Also if it does have a 12psi spring in it this means that i can't set my boost to 10 psi using my MBC. For me to set it to 10psi i would have to get a weaker spring correct?

Finally i have my boost gage connected to the nipple directly below the throttle body and at idol my gage shows no vacuum is this right or do i have it connected to the wrong nipple?

And would running 12psi until i can get a weaker spring on my setup damage anything? What would it hurt?

[burnout 180]

Can someone at least tell me if it would be safe for me to run 12psi?

That' s the factory boost cut solenoid.

no it's not, there's no such thing. it's the hot start solenoid, it's normally connected to the FPR, but you don't need it.

if it's connected to the actuator then you'll have problems
