did you win that turbo sharingan? when the bid with shipping got around 100 i gave up, sence that brand new knock off is just under 150 shipped.

PS Byakugan > Sharingan IMO lol

Yea, I talked to the seller and he gets a fairly regular stream of decent sized turbos. He's actually building a twin turbo stealth/3000gt now. I'll pick up the turbo some time this week and take measurements. According to the seller the housing looks "ported" and he estimates it could accommodate a while size or 2 larger....we'll see.

Lol, I personally agree, however when I made this account the byakugan wasn't even out yet.....yeah.

you guys are retarded the final version of the sharigan can't be beat by anything, anyone try using a s-trim wheel on the stock housing instead of the v-trim?

sharingan 19

iTrader: (16)

Perhaps...but I with the byakugan you could fight backwards and never expose yourself to mangekyo....lol

Anyway, anything would be better than the stock wheel, so I can't see why the S-trim wouldn't work.

cutting off the chakra points with 64 plams trigrams of the "gentle fist" style would render any jutsu useless FTW.

I guess what would be the "best wheel to have" between the H and V trim wheels. i was thinking the H trim would easily produce 300hp and have a stock like response.

...only problem is getting close enough to use gentle fist when a mere look in the eyes could lay you up in the hospital for weeks...

Ha! the stage 1 makes 300hp, and that's just a larger wheel in the stock housing. The knight sports turbos are good for 320+ and I think they use v trim wheels (in a T04b housing ). So I don't think it would be unreasonable to shoot for 350 on an H trim wheel.

if i can get a set of tail lights im watching for around 150, ill b ordering the ebay t04b and take to hybrid it. I'll be taking some measurements to verify the trim of the ebay wheel. so far all the ebay t04b turbos seem to have an inducer just slightly larger then a v-trim, but smaller then the H-trim.

neji can flash step, and he can see almost 360 without focusing and 360 with a small amount of effort. he doesn't need to look at you to see you.........

Good luck on the auctions, I was looking@ ebay turbos too, but some if them seem kind of sketchy about their sizing. For example the list in inducer as 50mm exducer as 70mm them call it a 70trim or some other bs. Hope u find a legit seller/company.

Personally I would rather have a byukugan, its more useful in everyday life and gives your squad a tactical advantage. However, in one on one combat the sharingan reigns supreme.

i also got the ebay to4e compressor housing and wheel and made it fit with the original s5 turbo. making it fit was tricky but doable, i grinded down the housing a bit, used 2 exhaust manifold gaskets and a steel spacer i got made at a machine shop it was about a 1/4 inch. it all fit nicely actually. the spacer went on the twin scroll part note that youll need two gaskets there now. i still have the spacer in my garage somewhere lol

I'll prolly just buy a sketch turbo. i mean the worst (smallest) it could really be is a v-trim right?

RotaryRocket88

iTrader: (7)

V-trim is not the smallest. I've seen a ton of T04bs on ebay that have smaller wheels, such as the 48mm S-trim.

Has anyone found a turbo that comes with an H trim wheel? I can't seem to find any information on them much less find one for sale. What did these things even come in?

i wonder what the ht18 flows in lb/min. just to compare side to side.

sharingan 19

iTrader: (16)

It flows ****...that's what lol. 35lbs/min maybe? I'm sure there's a calculator that could figure it out somewhere, I just don't care to look.

I not'm sure what this turbo is, my guess is that it was a v-trim or u-trim before the comp wheel contacted the housing. The turbine wheel looks fine though. So now I'm on the lookout for an h-trim wheel (or maybe a v-trim if its cheap) and a shop to machine the compressor housing...

Nosferatu

Size wise and the fact it's 8 bladed, most likely V-trim. Although the specs I've seen for V trim are 2.180" for the inducer ,yours is 2.056". I have a BW/schwitzer V-trim T04B sitting here like that one that's also smaller then the specs I've seen in the turbonetics catalog. Maybe there's a couple of varients of the V-trim wheels, the compressor map is labled V-1/V-2 ? Otherwise haven't a clue .

sharingan 19

iTrader: (16)

Its a u-trim. I measured it again, but this time using the shorter set of blades and it was 53.94mm, unlike the taller blades, these hadn't been folded in on themselves from rubbing the wall of the housing.

Also measured the turbine wheel inducer was 73.35 exducer was 61.03.

I figure if I have to machine the housing its not even really worth the effort/cost for a 1mm increase (u-trim --> v-trim) so I might as well just go for the h-trim (+4mm). Only problem is h-trim wheels are damn near impossible to find, much less for a deal. So I was wondering how an h-trim on the stock turbine wheel would compare to a v-trim on the p-trim turbine wheel I already have?

Nosferatu

Never heard it called a "u-trim" all the turbo houses i've seen (bullseye, etc.) selling the bw T04B turbo call it a V-trim and it's specs are 54.2mm/67.6mm (which seems pretty close to your wheel) .....I don't know why you would be bent on picking up a H-trim unless you had the compressor housing for it....If you have to machine the comp. housing then why wouldn't you just grab a 60-1 wheel, specs are very close and the wheel is easily available?

sharingan 19

iTrader: (16)

U-trim is 54.X mm
V-trim is 55.X mm
H-trim is 58.X mm
...so either the listing is misleading or their measurements are off.

Yeah, that's pretty much what I was thinking too. Looks like I'll be building a bnr stage 3 type turbo then because if I have to pay for the hot side to be machined too (plus shipping) then I might as well just send it to bnr and get a stage 4.

On the lookout for a 60-1 wheel....

Nosferatu

the specs are correct and it's probably not misleading as garrett calls them "V-1 / V-2" wheels, someelse coined them U-trim ...makes sense to call them that though.

Fleebay has lots of 60-1 wheels for sale.

ebay t04b is coming on friday. i'll be taking some pictures with my mic after i pull the cover off.

I think V1 and V2 refer to the 6 and 8 blade variants of the V-trim compressor. I listed them both a few posts up, and that info came from a number of sources. The U-trim term is something I've heard from a former Garrett dealer for the 54mm inducer, but 1.5mm smaller is a totally different compressor map than the V1/V2 55.3/55.4mm wheels. I have both an 8-bladed U-trim and an 8-bladed V-trim compressor with measurements matching the numbers above.


I machined out the housing on my turbo to go from U to V-trim, but only because it could be done at no charge to me. I was quoted $200 from a local turbo shop to do the same job, which was way more than I was willing to pay.

Going with a larger turbine should increase top-end similar to using a higher flowing compressor, so maybe an H-trim with the stock turbine would behave a lot like a V-trim with a P-trim turbine? There's so little info available on turbine sizing that's it's hard to say without trying it.

scratch the hybrid turbo for me right now, took the car on the Eway last night with the W/B and afc neo and would get 12.9-13 @wot twords 5K rpm even got to 14 at one point and detonated i think but luckly the engine seems fine. so im chaning the fuel filter to a 300zx TT and swaping my regulator with a new one i had laying around (i've had feared that the regulator might have been acting funny). along with the s5 alt swap (system voltage would dip down to 11.5-11.9 with the taurus fan on according to the neo) hopfuly one of these things solves my fuel problems because i was @ 40% positive correction and still no change to the afr up top.

sharingan 19

iTrader: (16)

First of all make sure your wb is calibrated correctly. Those numbers look way too high for a stock turbo@any reasonable boost level.......what were u boosting anyway? Recently my wb started reading high in low->medium boost/ high rpm situations (but not low->medium boost/low rpm). However it pulls hard and runs great. Turns out all but one of my dp bolts are broken which is apparently allowing extra air in and making my wb read lean.

Next, tii might wasn't to check your injectors, you can toe in all the correction% you want, but if an injector isn't opening its useless. At this point in time no stock injector should be trusted.

I actually came across a thread where someone asked brian@ bnr about the p-trim turbine. He said it would kill spool when paired w/ the smaller comp wheels (i guess that's why only the stage 4 /60-1 gets thee upgrade). Which makes sense considering the larger diameter and greater weight of the p-trim turbine wheel.

Since I'm looking for response and this is going on a 100k+ stock port motor I'm just going to find a 60-1 wheel and use the stock turbine (w/a slight clip). That way I'll only need to have the hot side machined when I upgrade it for the motor I'm slowly building in my room, lol.

I'm posting this from my phone and don't see your specs. If you have an rtek you should be able to tweak it with the neo and it should not be leaning out like that with the stock turbo. If you have th stock ecu I believe the afc correction starts to cause timing to advance. I could be wrong on that, but I believe I read it somewhere on here.

Setup is s4 Rtek 1.8, (4)720cc injectors, walbro 255, custom front mount, neo, 3" turbo back, s5 turbo, s5 jdm engine core, and trailing plugs in all 4 positions. engine is stock port and i also premix 200:1 (still have s4 OMP). see avatar for pic of car....

changing the filter helped a little, but the AFPR is acting funny and it was a cheap old ebay one so i've got a spare to replace it with tonight. along with the system voltage drop in the previous post so i'm swapping to the s5 alt.

I'm also getting some low rpm load ignition breakup, i'm thinking because of running the trailing plugs in the primary position to help prevent detonation. but that sounds like another ball of wax.

WB was calibrated that day.

i think i should be able to drowned the damn thing in fuel all the way to 8k if i wanted but idk??? if the regulator and getting the system voltage up doesnt solve the problem i'm going to take the secondarys out and have them rebuilt and flow mached.
