Hey wats up guys and gals. First off I blew the bottom end of the short block a month ago. I replaced it with the 02 protege NA short block. Everything on my blown block was swapped over. Dropped the motor in 2 weeks ago. Everything checked out good. The problem is evertime I give it half throttle, boost very slowly picks up for 1 second then feels like another hard pressure is keeping it from boosting, like a vac line is plugged up or pend. But if I accelerate very slowly to ride the boost, it picks up but not @ its full potential. Loosing 2/3 of boost power from the way it should be.
My setup is hard pipes relocated MAF sen.( 5 in. Away from throttle body) Using 1G gs-t bpv converted to BOV. Joep FPR and FCD, removed both flaps( forgot name vric? ) in int. Mani. Was Port/pol. too.
Everything else was converted back to stock.
I think my boost vacuum lines are hooked up wrong. I hear no boost leak from hard pipes and couplers.(checked 2wice/day for 2 weeks), Feels like Something is restricting the turbo to spool, can hear turbo spool, but late response and not as loud when barely half-OT. same result when its wide-OT but worse. I'm thinking vacuum line is hooked up wrong. The front end of car was replaced from collision from 1st owner so I don't have the vacuum line diagram from under hood-side diagram to make sure. running VERY LEAN in all gear and rpm. Sound like a very small hisss. Sound near throttle but can't locate vac lines. Help please. Any info would help. Don't want another boom too soon. If ur car runs right, take a pic of vac on int. mani(close up) And tell me where it leads to. That would help out so much.. Thanks guys n girls.
PM me is much faster for my to reply but either if fine.

Are all your vac lines connected on the intake mani? Check your VICS/VTS.... I know the top one if its stuck closed it will make the car feel gutless.

damn it, i have the vacuum diagram bookmarked on my other computer, and i remember it took so long to find on here since mine was removed as well. ill try to find it for you.

Stealth- yes all my vac are hooked up to my IM. But I feel like there's a leak under the throttle near the int. manifold. Everytime u have the hood open and let it idle. I can hear it but not very loud. But to the point where u can hear it. I blew into my wastegate today with the car was off. It was like blowing a balloon. (Its open). It stuck open 3 days ago that's when the turkey started. But I was already having problems with the vac not being hooked up right

Thanks for the diagram yudkib check your Pm . I think imma re-route my T's for my boost line source for a stronger, faster response.

 

[3.5familia87]

Does anyone know the best boost line source to tap in? I hear a lot about the brake booster line but I really don't want it to interfere with my brake system later on down the road. Or having 3-5 T's on same vac lines. This might help solve my problem also if I was to T at the wrong vac line.

 

[justanothermp5]

tapping the brake booster doesnt effect your brakes at all, invest in a vac block
thats the best way to get even/good vacuum to all the s*** you need

and it could be a boost leak, my car was doing sort of the stuff u mentioned when i had a few leaks, make a boost leak tester and see if you have any

edit: heres how to make one

J.A.MP5- yeah a leak is what I thought also to begin with. U can actually hear it when my car sits and idles.
sounds like an air brush right Below the intake throttle body manifold. I don't know if that's normal or not. But from what I remember, i've never heard it before unless its the both flaps I removed?

- On the brake booster line, which one do I tap? Cause I thought I saw 2 vac lines. Unless the bottom line is for hydraulic only. And how much is the Vacc Box?

 

[yudkib]

ive got home made ones for $25 shipped, with fittings. if you go with a major company like vibrant, expect to pay double that for just the block, plus another 20 or so for fittings.

 

[3.5familia87]

Is there any photos of the vacuum box. I'm definently interested. How many vacuum line's can u hook up?

 

[yudkib]

how many ports do you want? $25 comes with a total of six ports... assuming you tap your break boost, the BB in and BB out would be two, leaving you four accessory ports. additional ports are $3 each. click the vacuum block link in my signature, theres a pic on the first page... the ones with the flat faces.
