I purchased last year a small port to big port manifold adaptor from T3. Its barely been used, was on the engine for no more than 50kms and still looks shiny and brand new. At the time it cost me $160 new, now all I am asking is for the same back. If you tried to get a new one now you'll find they are ALOT more expensive as the exchange rate has fallen hugely since I bought it.

For those who don't know, these are used in order to run a RWD manifold on a small port in most instances. They can also be used to adapt any other manifold too.

So it'll set you back $160 and I'll even throw in with that a set of big port manifold bolts, studs and nuts which you'll need to swap onto a small port motor to make it work.

Note, that was taken when I first got it, but it still looks the same, its just got a bit of silicone on it which I am cleaning off now.

Located in Wollongong NSW, but I am definitely willing to post.
