R33 Jerking

[skyline33]

A friend of fine has just installed a massive FMIC but after the installation took place the car seems to reach a boost cut and dangerously jerks around the 4000rpm. the cars is an auto has a pod + exhaust nothing else was changed apart from the intercooler the car is running standard boost (car has never been boosted).

Also what we have done is blocked off the hose that used to go into the intercooler pipe.

Any ideas??

Not the wee little hose that goes to your boost solinoid

its the hose that is coming out of the T connection going into the standard intercooler piping

Hey Guys,

I take it you installed a FMIC Kit (possibly a Hybrid). Great kits but they failed to provide one thing the nipple on the pipe in the same position as the stock one.

I did not take a chance with mine as figured it must have been there for a reason, so I got a local welding place to put brass nipple mounted in a peice of aluminium and drilled a hole in the pipe and aluminium welded the whole thing in so it created a seal.

Attached the hose to it once installed and got on with enjoying my new found power.

get this done dude. If you want pics of mine just pm me.

Cheers,

J-Flash
