Hi boiler. Purdue fan? Thanks for the response. It was you, or you were one of the ones I remember. One of the posts I read through was the one where you had your nice box opening of the 28R from Garret. Pretty box. I believe there was someone else with a black civic in their sig who was running a GT28, or a 25? He was very helpful in this forum as well. Anyhow.
As for the turbo's, where I would be getting them from, what specific kind, either ATP or Dezod. I should've referenced them instead of being vague.

Now, even amongst those, there are differences between them. I suppose dezod and ATP simply spec them differently for their own sale. The two GT28R's are identical, except the ATP one has the option of a .48AR turbine, but that option is only available on a T3 turbine housing and loses the internal wastegate. I believe with the .48AR/T3 housing option, that should bolt up to dezod's log manifold. However, the standard 64AR from both dezod and ATP will have to mate with the HKS T25 footed flange. I prefer the .48 for the faster spool up time. What's the downside to turbine AR's? If I understand the compressor side, the higher AR tends to take a while to spool up and compress the air, but ultimately can compress more air. The lower AR is more responsive in getting up to speed but has a lower capacity to compress and flow the air. Is there some kind of trade of like that as well on the turbine side? As for the 28RS, ATP has the identical one as Dezod, but more turbine wheel options. They have the same .86, but also have .82, .63, and .48 available for T3 turbine housings. It seems the .48AR for the 28R has to be used with an external wastegate, hence why I would like to use it with the dezod manifold, since it has a bolt for a 30 something mm wastegate and will mate with the T3 housing. for the 28RS it seems that even the T3 housing option uses an internal wastegate.. or atleast on the website it doesnt state it requires an external wastegate. If that's the case I can still use the dezod manifold and just get the block off plate.
Also, I suppose either way I would have to get the downpipe custom fabbed. Big boo there. I would still purchase the charge/intercooler pipes and try to get those modified instead of fabbing totally new ones. I expect the routes to be similar, although not an exact fit. Like anything is ever an exact fit..
As for the motor, I have forged rods, would need pistons, sleeves, and I'm debating a block guard. That will be done BEFORE the turbo. I'm a big stickler on planning and doing things in the order I need them. But I know I can't plan out every last tie, grommet, hose, etc, hence the desire for dezod's kit minus the turbo. And minus a few other things.
Another one of my worries is the fuel system, would a walbro pump and srt4 injectors be sufficient to support 250 hp? What's their cieling? I know RSX engines will most likely lock if I try to use those. I would like to keep the fuel system simple with just those two upgrades and managed by standalone, not interested in converting to a return fuel system.
Anyways, I know this is more of a paragraph than a question, but if you or anyone could just kind of verify what I've said is correct or incorrect. I apologize for the essay. Hope I didn't ask any questions that've been already answered, but I did search rather thoroughly.
EDIT: Also, I tried searching for this but couldnt find anything relavent. Log vs Equal length runner exhaust manifolds? Advantages, disadvantages, comparisons. Aside from price ofcourse. I'm po' right now, because I just finished building a new gaming rig, but I do have a steady job and financial aid checks galore, and I'm a patient man. That being said, I don't mind waiting to save up to get a more expensive manifold IF it's worth it, aside from the fact that its pretty and I can call it medusa and pet it when not hot.
Also TFNAFF, thanks for responding, you helped me out with my other questions as well. That is a nice turbo, but it doesn't seem like I would use that to it's full potential? Couldn't I get Disco Inferno and achieve the same results I desire? 250-300whp? I say that now, but a year or so from now when all this is done.. I'll be wanting more..but the 2860 and 2560 seem like good starting points for now. Although I'd like this to be a one time, meticulous, done right installation, especially if pipes will have to be fabbed. So I don't plan on changing anything later on.
Also, did the two of you custom fab your downpipes? I presume you did, just wanting confirmation.
