Silicone Reducer/joiner Size (Rb25Det)?

[Torques]

I would like to change the pipe joiner in the picture with a silicone part.

Would anyone know the correct diameters?

I have a rough estimate of 67mm -> 62mm but can not find any straight reducers that size.

Any ideas who is selling these?

Cheers ..

I would normally do a 2.5inch straight and give it a slight stretch over the aluminium cross over side

[blah_blah]

Thats a 3inch to 2.5inch isnt it?

2.75 to 2.5

2.75 to 2.5

It's 2.75 inch on the t/body. 2.6 inches on the crossover and 2.4 inches on the od of the intercooler pipe

I'll measure one when I get into work

Lol sucks to be me

I measured mine at night with the old hoses still on, thought it was 3 inches on the t/body and then 3 to 2.5inches to the intercooler pipe.

And I just ordered my silicon hoses for it yesterday.

She'll be right...!

It's the Aussie way!

Hello there,

Thanks for the answers.

Yes, I tried stretching the 2.5'' I have but the joiner won't give in that much.

(which speaks for the quality of the part)

2.75'' seems to be the closest to the OD of the intercooler side then.

(still it sounds a bit wide ..)

I gave up looking for the right size so just went to wreckers and bought like 10 stock ones to have in case they break.

Turbo smart 2 1/2" went over mine but no chance at the throttle body

Hmmm .. thanks,

But it looks as if your piping is different?

#As for the throttle side I had no issues sourcing a joiner.

(I can look up what I used if you want ...)

It's been a while but ->

A 63mm joiner does the job.

It's a bit of a compromise, but works.

One side of the Nissan piping is 60mm, the other 66mm

The length is 76mm.

Cheers
