    • Massive thanks to all who have shared their knowledge here. Taking the time to post up the info is appreciated. Its saved me a few headaches and now hopefully on the right track. Ive a spare Evo1/2 pipe sourced and winging its way to Morrison...

      Mine has a MD300201 stamp. I removed it by myself, so I am sure this housing is taken from a stock EVO 2. I think yours is a EVO 1/2 housing. I had a couple of EVO 2 housings more before and IIRC they also had a 201 stamp. The EVO 3 O2 housing...
    • @DSMPT Can you make out the part number on the Evo1/2 outlet? Is it MD300200 or MD300201Amayama is telling me it MD300200 is the outlet for both the Evos. So CD9A Evo 1 and CD9A Evo 2/3 which isnt definitive.Mine is MD300201 which is starting...

      EVO 1 and EVO 2 have the same O2 housing/down pipe, but EVO 3 is different. Besides the EVO 3 O2 housing flange angle, here is the port size comparison. You can see that the EVO 1/2 O2 housing have a larger inlet port diameter than DSM and the...
    • The Morrison setup is going to be the best scenario, but if you are encountering boost creep, you might also do well with an enlarged wastegate port on the stock turbine housing. I bought a 7cm turbine housing with a 34mm wastegate flapper valve...

      I don't have the EVO 3 O2 housing anymore, so I can't take new comparison pics. But I still have the EVO 1/2 O2 housing, so I took some pic with DSM O2 housing. The last 2 pics are old pics I took before. Left is EVO 3, Right is DSM.Left is...
    • Mine is an EVO1. The EVO 1, 2 and 3 differ from the DSM units which as I can gather is what's indicated above. Hence the need to find a stock frame to compensate for this adjustment.Evo 123 Turbo units are all the same, Evo123 Down Pipes are...
    • +1 to JNZtuning, Josh is very knowledgeable and they've been my go to for well over a decade.Where it meets the downpipe. Old RRE pictures of the angle difference between evo3 and stock dsm o2:
    • miller_63 reacted to DSMPT's post in the thread Wastegate Fitment Query. Evolution 1 with Like Like.
      Please note that EVO 1/2 O2 housing and EVO 3 O2 housing are not the same. The flange angle, outlet port size and 2 studs center to center distance are different.
    • Hey, do you mean the outlet of the 02 housing where it meets the Downpipe? Or the outlet of the Turbo frame?
    • Bump.Still on the hunt for a stock OEM Evo 1/2/3 O2 Pipe. Anyone please! You will get it back once Morrisons have the template.
    • Aw lads, they just look unreal!Desperate to find a stock Evo 02 Pipe to ship to ye....still looking! Ill bounce the thread up again.....
    • If anyone reading this as a spare OEM O2 Evo 1/2/3 Pipe and is willing to part with it please let me know.I need to source one for Morrisons Fabrication, shipping from Ireland is extortionate. Prefer to find one in the US from someone willing...
    • I thought they already done an evo 3 system for some one, maybe i was wrong then. JNZ tuning is a DSM original company thats been around for ever. they know alot of builds and do builds themselfs so might know about the fitment on you E3 o2...
    • Been speaking with Morrison's, they would need the OEM 02 housing elbow to replicate it. Adding in costs exporting that from here to US.Who are JNZ, forgive my ignorance?
    • I've emailed both Punishment and STM on these kits and not one response received from them at all which is a little disconcerting.All I'm querying is the actual fitment on an Evo 1. How close or how far off are they likely to be! Would love to...
    • A combination of porting and smoothing the inside of the hot side + running an external gate solved my boost creep issues on my EVO 3 16G turbo. I also did not want to pay so much for an aftermarket O2 housing so I drew and cut my own stainless...

      If you want something as beautiful as it is functional, Morrison Fabrications has something for you. Just tell them what wastegate you want to use.https://www.dsmtuners.com/threads/new-product-testing-dsm-stock-replacement.526288/...
    • I run a FP manifold and a hybrid 16G E3 also, 2.5" DP and 3" DP back and I dont creep! But i did heavily port my turbine housing and im using a punishment racing o2 housing. I want to say you might not need to go external and just port your...
    • Thanks for the input everyone, has anyone who fitted these noted any difference with the stock downpipe exhaust....is it going to need butchering to fit?On a side note, just how loud is a downpipe screamer. It certainly would make life a lot...
