I have a 1993 JDM Fd3s twin turbo. It has quite a few mods, but nothing major. So stock ecu, stock turbos, no boost controller. I hooked up a boost gauge a little while back and the most it would ever read was 5psi. I figured maybe it was a broken gauge, cause it feels like it has tons of jump still. But back in Jan i was taking it to storage and i had the hood open and it was pretty cold out. And i could actually see white vapor coming up from the drivers side of the engine bay towards the firewall. So im guessing my leak is somewhere around there...Any suggestions would be great. Thanks

 

Hey nick

Under the lefthand side of your batt neer the Stock Blow off valve their is a little 90 degree rubber hose that gets very hot and likes to crack alot - so check this out - you will need to remove most of your left hand side to get to it -

here is a pic of my boost problem i found when replacing parts with silicone hoses

 

Thanks a lot, that was exactly the kind of response i was looking for. Know that i have an idea of what to look it will make it a lot easier. Hopefully its as simple as that.
Now that midterms are done kicking my *** i try to check this out this weekend!

 

Check that but also remove each large coupler between the turbos, intercooler and intake elbow. You must remove them and work/stretch the rubber to inspect for cracks or cuts. You can't see them on the car.

 

Alright thats very helpfull. thanks!
Ill let you guys know what i find this weekend. Thanks a lot.

 

How did it go ?
