My friend is upgrading everything on his car from 2.0 to 2.5 but not the ecu. Currently he has a tune for a stage 2 ej205 with stock td04. Mods like front mount and tgv delete and obviously exhaust. He is switching to a 255 with forged pistons, oversized valves. AVCS deletes (wont run on the old ecu anyways) break in will be on a 19t td04 and he will be switching later to a hta68 with divorced waste-gate I believe. Still doesn't have all the parts for the next turbo set up so anything could change.
Lets just do a spec list cause bullet lists are easier then word problems
255 block
255 crank forged, non-nitride
255 conrods
Weisco 100mm pistons
11mm oil pump
WRX oil pan/Pick up/baffel
King bearing set standard size with extra oil clearance
255 heads with upsized valves and AVCS deleats
205 cams
840cc witchhunter injectors with milled fuel rails and parallel fuel delivery
walboro 255
rotated 2.5i intake manifold
DBC TB
custom adapter plate to fit DBC TB on DBW manifold
3" hard inlet with couples to fit 3" turbo inlet or 2.4"
FMIC
Megan 1 piece headers and up-pipe
19t td04
remote ebc
wideband monitoring
I think that is all the important stuff. I am just looking to see if I can find something close to bring the 2L tuned ecu to a 2.5L set up and then get some logging and tweak somethings. Hopefully we can get a full dyno tune when it gets the hta68 since that will be the final version vs the current break in set up
