I had a cracked exhaust housing (the welds only actually) with my DOM3, but we welded it ourselves (preheated and all) and it held up better then before
After welding done right, they are definately worth keeping imo.

dom3xtr's with 8cm now available huh? should help reduce lag and still make 400whp with proper supporting mods.

07 with only 17k miles stock block/clutch running 93 no meth with tgv's deleted, inlet, 70mm cai, id1000's, gs ebcs, aps tmic what would the realistic numbers be with a 3xtr and 4xtr? car will be daily driven but i want more through out the entire rpm range especially on top

Are most people still running an IWG with the Dom 3? I'm planning to do a Dom 3.0 XT-R on my V7 swap sometime, as soon as funds allow. I was planning to get 1000cc injectors, just to make sure I'll have plenty of fuel, and keeping it IWG for now to save some money. Any EWG funds I'd have at the time will most likely be going to a clutch haha I have an Exedy Stage 1 now, but I doubt that's going to hold the Dom 3.0 CT-R power levels.

I have a dom3xtr, my boy bought the dom4xtr. not much difference in terms of driveability. If you want more power, do the dom4xtr. I'm going with the Dom5xtr next time around lol.

386/363 21psi, 2.4" inlet, 10cm hotside... 23psi, im sure it could make 400whp. EL headers may put me over 400 too.
on the dyno it seems to spool kind of late, not going to lie, but on the street, spools way sooner, I want to say between 4300-4500. dont think of it as a bolt on turbo, think of it as a 30R. people say the XTR's spool late, they are bolt on... but still big turbos (dom 3, 4 and 5). now if you are going from a vf39 to a dom3xtr, you might be dissappointed at first lol. i know i was at first, because it spools later, but you will have wayyyy more top end and when u put your foot on the floor, the car will MOVE OUT.

if you still are not sure, I believe the HTA green from FP, makes similar numbers and spools a little sooner. i went with blouch because their customer service is supposed to be second to none and blouch has two options 8cm and 10cm (8 will spool sooner)

DOM5
i would say check out some dyno videos. you wont find much on the Dom5. i've been looking for the longest. whats crazy is, the dom5 came out two weeks after i bought my turbo lol. i probably wouldve gotten that. i just asked Blouch about the dom5 last week. they say it should put out close to 450whp.

i' sure if you got the 3" inlet then you would have seen better numbers as well as tgv deletes. 4300-4500 really isn't too bad imo because i drive around town without boosting, i shift between 2800 and 3200 just for economy and to keep noise and speeds down. essentially a dom3xtr 10cm with proper supporting mods nets you at minimum 375 with the boost turned down low, right? so its safe to assume a 4xtr would net you about 400 at the least amount of psi. of course a stock block might not hold up very long to a 4xtr, even the 3xtr is pushing the stockers limits. the 8cm housing should combat the low rpm lag and start it a little sooner but do you think it will take away from the power all the way to redline? will overall hp/tq suffer drastically due to the small housing? i honestly don't think i'd regret going for the 3xtr, however i just dont want to regret not getting the 4xtr for only 100 more. stupid stock block is holding me back from big numbers. however knock on wood shes an 07 with 17k original miles and both leakdown and compression are perfect, practically no blowby in the tmic and the clutch, tranny and diffs are perfect

You will lose some top end power with the 8cm housing. I'd say you should be around 350whp at around 20ish psi on almost all dynos (some will be higher) largely depending on the dyno, altitude, and octane used.

I loved my dom three, even on the 2.0L. Was reaching 20psi by 4600rpm (even at altitude). 30psi by 5k. Very very fun car. I'm excited to see how much quicker it will be with the 2.5 that's being built.

I can't imagine going any smaller than the Dom 3. Honestly, if I knew I would end up going 2.5l anyway, I would just got the Dom 4.

I do not think the 8cm will cause ur torque to suffer. if anything u might get a little more than me because of the quicker spool. most people with 2.5L's have hp and tq numbers that are closer. my tune was on the conservative side. if you do E85 or race gas your numbers will naturally be higher... and yea with the 3" inlet and tgv deletes, my numbers may be a little better but I wasnt sure i wanted to do the tgv deletes so i went with the 2.4" inlet.

^ what he said lol... i couldnt imagine doing the 2.5XTR after having the 3.0XTR. I would say Dom3XTR or bigger lol.

yea i def recommend a hard inlet. the newer perrin ones are supposed to be pretty good but with a hard inlet u dont have to worry about collapse under high boost at all.

got a quick question for you gurus, on the ej257 with water meth 50/50, Dom 3.0XTR with PE800 injectors with an aggressive tune to around 450whp, would you say to change a WALBRO 255 pump to a bigger pump?
