turbo ordered! only a matter of weeks before this puppy goes in.

presure2 or anybody thay had a hand in supershannon's set-up. do you think there was room for the internal wastegate? it's cheaper than a tial wastegate, then the flange for the extrnal can be blocked off (saw a block-off plate on atpturbo.com for $10) and then I don't think the oil filter and oil cooler would need to be relocated. thus saving even more cost. just a thought. or perhaps having an external wastegate flange welded onto the manifold to put it in a different place? there's a manifold from 935 motorsports that looks like a stock manifold, but is t3 flanged and has a wastegate port out of the top of the manifold. it says that a 90 degree adaptor is needed for the wastegate to get the hood to close, but I think it just might be able to fit on out cars without an adaptor. here's a linky: https://935motorsports.com/catalog/product_...roducts_id=1478

i wouldnt trust a turbo that big NOT to creep with an internal gate.
creep is something we CANNOT have with larger turbos, creep = death to the 5s.
the manifold you posted would work, i dont know about closing the hood, without an adapter.
again tho, with how the WG would be positioned on that manifold, i would be concerned about creep.
im tellin ya man, dont try to cheap out here, i know you dont have a lot of money to spend, but this is one of those critical things, that really gets important the larger the turbo is.
boost control is going to be crucial to your setup, i wanna see this beast make great power AND last more than a week or 2.
dont you already have the relocation parts from your 5sfte?
i would keep my eyes PEELED on mr2oc and alltrac.net, and the supraforums for a used gate, if money is that tight.

so, turbo was shipped today, but it's gotta come a long way before it gets here so it might take a while. also ordered a CT-26 to T3 adaptor off ebay. I think I'm gonna wait for those two to come in, and then I'm gonna head over to ATP turbo, which is about 45 minutes from my house, to pick up all the remaining flanges, gaskets, oil lines, and a tial wastegate. I might be able to use my current feed and drain line, but they might be too long. I'll have to wait until the adapter and turbo get here.

also, I do already have the oil filter relocation equipment, but I'm thinking the lines will be way too long now. I think my hose ends are re-usable though, so maybe I can just cut the lines and re-use the hose ends.

still waiting on parts. anyway, anyone have any guesstimates on the amount of horsepower I'll be making with this turbo? I ordered a TiAl 38mm wastegate with a .7 BAR spring, which is 10.15 PSI, and I won't be taking it any higher than that anytime soon.

also, the highest horsepower 5sfte I've heard of is Shannon's at 240 WHP. but I don't know if people have made more than that with mr2's or camry's or whatnot. anybody heard of anything higher?

10 psi is alot to start with on that turbo.
mike colon made 515whp...

515 WHP? on a 5sfte? 5sgtes don't count. I'd like to see a mod list on his car.

His fully built.

I heard of someones being 750whp a couple years back... don't know who's but I think it was an mr2

it was a 5sfte not GE.
it was FULLY built, with acell EMS IIRC.
thats gonna be what stops you more than anything. tuning.
again, i would DEFINETLY get a 5psi spring, and the 10psi spring.
with the 5psi spring, your max boost will be ~11psi .
ive seen 3s dynos of ~270whp @ ~15psi or less. so your gonna have to be carefull of how much boost you run initially.
and PLEASE tell me you have a wideband, and are planning to hit the dyno as SOON AS ITS INSTALLED?!?

I've got an AEM UEGO wideband. but I was planning on tuning it myself with that for the time being. I got my ct26 tuned pretty good by myself. it stayed between 11.2 and 11.6 through-out the RPM range at WOT up until about 4500 RPMs, it dropped to about 10.7 or so.

anyway, I want to tune it myself for now and then perhaps have it tuned professionally after I get the water-methanol injection. tuning is $150 an hour here.

im not saying to pay for tuning, im saying tune on a dyno.
where you can get easily repeatable results over and over, without endangering yourself, or others in the process.

dunno if they'll let me tune it myself on their dyno. I wish we had a load bearing dyno at school. all we have is the one for smog tests... apparently they do have one, but when they were expanding the auto lab and decided to put an actual class room in, they didn't have anywhere to put it except over top of the dyno... so apparently there is a perfectly good load-bearing dyno underneath my feet everytime I go to class and it just kills me to think that it's being wasted. anyway, I should ask turbohoses how much it would be, but it would probably be more than modacar since they mostly do high end cars like ferarris, nobles, porsches, lotus, and lamborghinis... but I'll ask

I'd like to see the street brawler kit on a 5sfte. Ball bearing turbos are awesome, but think about the wheel spin from a insanely fast compressor spool. I have gone back and forth with the street brawler kit & GT3071R. It all comes down to acceleration characteristics. I think the street brawler 46 trim would be the way to go. Thats what I'd like to put in my car. You'll still have great spool time, make excellent power, and have the potential to make more power over the potato.

got a bit of a noob question here,

what is the trim on turbos?

cos i've found a few t3/t4's that im likin the look of, one says its .50 trim and the others .57. i'm after some good mid rpm range boost, not insane tyre frying kinda stuff.

whats considered too big for say around 10psi on a 5sfte?
