Default EBCS vacuum line question

Total noob question here. I'm replacing my stock VF52 with an FP Green. I have a COBB EBCS. The vacuum ports on the FP Green are huge compared to the VF52, so the vacuum lines (boost and waste gate) off the EBCS won't fit. Do I 1) retain the stock vacuum lines and use a step up adapter at the turbo, 2) run bigger lines from the turbo with a step down adapter at the EBCS, or 3) is there an EBCS out there with the same size ports as the FP Green that I can run bigger vacuum hoses with? Would appreciate any suggestions.

You can get a kit with fittings and larger hose from Cobb that should work for this application.

The larger hose and fittings ensure a clean vacuum or boost reference for ideal tuning and operation.

That is hilarious! Thanks so much for posting so quickly!.

I actually asked COBB if they had this very product, here is my question and their response (I left off the tech's name, no need to embarass the guy):

Hello Adam,

Thank you for contacting COBB support! As it turns out, that is not something we have tested in-house before and we also do not offer separate components for the EBCS. Sorry for the bad news. In this case, I would recommend reaching out to your tuner for better guidance.

Let me know if you have any additional questions.

I bought a COBB 3 port EBCS many years ago and it's been working great with my stock VF52.
I'm installing an FP Green turbo and the compressor housing and waste gate ports are a lot bigger then on the VF52. Is it possible to put bigger ports on the EBCS (Do you provide parts for this including the larger hosing?? )

Thanks,

Adam B.

Thanks for the heads up. I ordered the COBB kit, we'll see if it shows.

Purchased the COBB kit referenced by Kermit, arrived yesterday.

Took about 20 minutes to install. Easy set up.

Now to try and shoe horn the Verticooler back in around the FB green.

Looks like its going to be tight.

you can change out the fittings on the EBCS to match the size. you will need a 1/8" npt to 1/4" barb fitting to replace the one where that lines goes. Personally I would just change out the one on the EBCS that feeds to the turbo and leave the others stock size
