Turbo technics spec

Postby Dansta » Sun Sep 23, 2018 8:16 am

Hi folks.

Does anyone know the turbo spec used on the TT single kit (2.8)? I would like to know the turbine A/R and Compressor A/R.

I did email TT but didn't get a reply.......

All I seem to get able to find is that it was a T3.....

Alternatively, if anyone has fitted a T3T4 hybrid, what A/R worked for you?

Thanks Andrew. I already have this document and it does not provide mreo detailed turbo.specs......... but it does help with some of the wider elements of the turbo setup.

Thanks for that. This. That is a lot of boost you're running. I appreciate you sharing your specs.

I'm only going as high as 12psi probably. Cheers.

Is there a list of parts anywhere for viably replicating the TT conversion or would it need several parts fabricated from scratch these days to do any turbo installation on a Cologne ?

@Not_Anumber The link Andrew 2.8 put at the top gives a good list of the parts needed.

Ultimately the 4 most difficult items imo will be the manifold, cross over pipe, vacuum cartirldge and enrichment block. I managed to find a really cheap Efi 2.8 so I've moved away from mfi. I also managed to find a Turbo Technics manifold on eBay so I just need to fabricate the cross over pipe. Everything else like intercooler etc I will just sort out as I require. I might go for an oil catch tank instead of the vapor pressure valve thingy quoted in the TT spec. Happy to discuss what I'm doing in more detail if you PM me.
