St215 (caldina Gt-t) 3sgte into a St185 Celcia, Vacuum Lines help

[90CelicaGt4]

Hi Everyone,

New to this forum, Hoping someone can help with this. So I have put a St215 3sgte into a St185 celica Gt4 and i have these two vacuum lines open. Does anyone know what i need to do?

The engine currently will run for about 1 minute and then it will slowly fade off and stall (revs will drop). I'm thinking it maybe these lines open?

By the way these ends are just under the throtle body
Please help

Welcome to Toyota Nation! I just had a look at my brother's GT-T and from what I can tell, the larger hose goes to the airbox and the smaller hose goes to the factory BOV. His hoses have been blocked off because he's running an aftermarket BOV and a custom cold air intake, but that's where they led to previously.

Yes, sorry, was meaning that his hoses have had a screen placed over the ends of them so that it can still breathe but can't suck in foreign objects.

We were going to use a mini filter but it was cheaper just to use a stocking and tie it on with a cable tie . From memory we did that with the two larger hoses, but used the line for the original BOV as the vacuum line for the aftermarket Blitz BOV

No problem mate. Don't use the nipple on your CAI piping as your vacuum source. Make sure you use the original BOV vacuum line.

Here's a pic of which hoses are which - The only one you need to connect is the BOV vacuum line to your aftermarket BOV:

the one you your pointing to is the big hose eh that went to the bov not the the lil one in front eh the bigest hose that went to the standed bov
