Stock Rb25 Tb And Turbo Inlet Size

[89CAL]

Hi

Just want a quick answer cause I have been searching and couldnt really find much and want to order some silicon hoses now

Just want to know what outside diameter the STOCK throttle body and STOCK turbo inlet is, or better yet what size silicon hose will slide on properly lol

Thanks

nooone? Im fairly sure for the throttle body I'll need a 2-3/4" Silicon hose but i cant get to the turbo to measure it. someone must have a stock one laying around that they can have a quick measure for me, even if it is only a rough measure

pretty sure the inlet of the turbo is 56mm OD

so a 2 1/4 coupler will fit it.

and the throttle is 70mm and a 2 3/4 coupler will fit.

Dont quote me, but im pretty sure theyr correct.

go to super cheap and ask them to try a few sizes in the carpark, bring an 8mm ratchet with ya to get the hose clamps off.

Just talked to a mate whos replaced all his hoses and joiners and he said

TB = 2-3/4"

turbo = 2.5"

So theres 2 opinions for the turbo.... There a third that wants to jump in and settle it?

yeh my bad, its indeed 2.5"...

awesome, all matches up now so i know wat I need

Thanks for that mate

no probs.

those silicone couplers are pricks of things...

expensive for what they are, and youve always gotta get EXACTLY the right size lol
