Yes - intake changes likely to alter airflow

where can i get a forward plenum for an r32?

eBay or make one.

I've had one made up using a GTR plenum chamber and stock runners with a Q45 flange on the front. Another guy has done it with stock runners onto GTR ITB's (think that was a 25 though, much of a muchness except the 20 runners come out on worse angles). Have had to have a couple of goes at throttlebody placement and head scratching over the water outlets but it has come along nicely, has cost about 2/3 of an eBay plenum so far and I can trust the quality of the material and welds. Results will be posted when engine is running

Edit: not an RB20DET but an RB30DET with an R32 RB25DE head so same same
