Is the gt28 water an oil cooled?

Im getting my turbo from a company called HyperGear over here in Australia. So while their not genuine GT series they are the equivalent to the specs just no Ball bearing.

The turbos a sleeve bearing and i can choose whether i want to run water and oil OR just oil. Im thinking just oil.

Like yourself, ill eventually switch to MR2 tranny but mean time ill stick with stock gt. I think ill go gt2871 because they already spool great on mr2oc.com guys cars + .2 capacity would be pretty good torque curve. But i dont know about upper rev range, eg. FE head. This is somehting i havent really researched yet but i cannot see the FE head being an extreme limitation. I want the car to make about 220-240FWKW which the GT2871 could make however, it would be on its upper limits, whereas GT3071 could make 280FWKW but means increase lag, etc... but thats just too much power.

As mentioned, the car will be used on weekends with some track time: stripped interior, full suspension setup etc...

I just think ill got GT2871 and if the time comes that i need more power then ill go GT3071...

i like the 2871 but ive heard of creep issues with the internal gated one.

yup. without a doubt an internally gated '28rs is gonna creep on a 5s.
the 3071 will spool faster than you would think.

the 5S-FTE should actually spool a little faster because of the torque the engine makes. the longer stroke of the 5S will help with the spool

And this time remember to put on a BOV.

Definitally will I have a cheap ebay one thats why I took it off.But I guess I need a good one whats a good one to get? the hks one?

Haha ok. Yea the HKS SSQV is really good.

i dont get this thread.
seriously.
you ask for help. people try and help, you do the totaly opposite anyway.
youve changed the title of the thread what, 4 times now?
again, i will suggest that you use the search button here, and on other 3sgte based sites, use google search, to do the proper research about things BEFORE you post, that way, when you DO post, it makes some kind of sense, and you can provide proper details about what it is that you want to do with your engine, so that you dont have to make 15 diffrent posts in a weeks time about basicly varitaions of the same topic.

Well you said dont make new threads so I used a old one. I have not been oline for long I just got a pc last year I am not a pc person so I dont know how some things work. As far as you say I ask for help and I do the total oppisite what does that mean?

im not trying to be rude here, just trying to keep board clutter to a minimum.
what im saying is that by doing a little bit of research BEFORE you post, you can often find the information your looking for without posting at all, as is the case with 99% of the posts youve made here.
not that posting is a bad thing, in fact quite the opposite is true.
however, you need to understand that alot of the stuff your seeking answers to have been covered MANY times here over the years, and you just need to look around abit to find it.
we were all noobs once, gotta learn this stuff somehow!

what i mean by asking for help and doing the opposite is, youve posted here about which turbo to get, what turbo does what, and how this or that turbo will spool.
once we gave you are opinions, you went ahead and bought a turbo that is terribly matched to a 3sgte, and with the large housings and small a/r are just going to spool slow, and make less power overall than a properly matched turbo to your goals and setup.

Ok I am getting mixed opinions on this turbo, Your the first to say not a good turbo. 2 members on here that was the only 2 to give me there opinion besides you said thats not a bad size turbo. Intake .60 ar & .63 ar exhaust. Also I am a member on mr2oc and many people on there aid its not a bad turbo. Sure It will have lag but will have a great top end, atleast thats what I got from the whole thing. Also I see a few people on the other site that run these even bigger. I figured the gt35 with .82ar was big so this was smaller and good enough for me. What rpm do you think I will hit full boost on the gt32? IIt should not be to bad as long as I hit full boost at 4000k I like top end better my car spins to much when launching so this turbo might even it out?

gt32 deal fell through maybe for the good. I decided to get a ct20b from Jim hope I am on the road again soon an I just ordered a new bov

donald, your turbo will be shipped to you in a couple days.

CT20b was the best plan.. only get the Gt35 or GT32 if ur building a weekend car.. had GT35 installed couple months back.. and I was replacing and breaking things every other day, i went back to stock since and im happy.

I installed the turbo but it wont boost past 6-7 lbs and boost is hard to build its very slow. I was thinking when my old turbo broke maybe it tropped a code or I am in low boost? I did not reset the ecu do you think thats the problem is reseting the ecu a must when changing a bad turbo? I might have bad hose going to the turbo to the acuator I will change the tommorow and reset the ecu by pulling the fuse. Also noticed the wastegate flap is not shut firmly its shut all the way but theres alittle play. Will this cause my problem also? It dont sound like the tubo is spooling up fast nor a big amount. Any help would be great thanks

sounds like your wastegate is stuck open, or you have a major boost leak.

It's also always a good idea to reset your ECU anytime you change anything major. That being said the ECU only keeps you in low boost mode until the next time you turn on your car - Presure2 is most likely correct. Reset your ECU and check for leaks everywhere.

no boost leak I tested that for about 3 hours sunday and found none. I mad sure I had all new high quality clamps and couplers and have as less connections with couplers as possilbele most of the pipeing is welded together or is solid pipe with out many couplers used. When I installed the new turbo to my old acuator the flap seemed to be a little loose maybe the flap is the problem

do u have an aftermarket downpipe?
