gt28r...three quick questions
this is the turbo im getting this spring..ive searched and couldnt find responses to these questions specificaly.
1. Do they have to be water cooled.Im not to found of having to run coolant lines
2. For those who have them,are there creep/spike issues with them..i have these problems with my 15g and i want to bolt a 3 in downpipe to the gt28r and dont want lots of problems like i have now
3.It has funky inlets and outlets,do the pieces to bolt charge piping and inlet piping come with it or where can i get them.
other than these questions,it seems like the perfect turbo for me

Re: gt28r...three quick questions (second edition)
yes they have to be watercooled... if not the bearings will prematurely fail, i have talked in person to numerous garrett engineers, because the bearings are stainless and not ceramic they expand faster than the steel they are housed in... water cool to the turbo or watch it die a quick painful death

i read this whole thread..some (like yourself)said it has to be watercooled and others said that if you let it cool down and change oil often,that it doesnt mattter.....either way, i need a new radiator and while the coolant is drained im going to go ahead and do it.

Re: gt28r...three quick questions (second edition)
dont listen to them... im buddies with the people that made the damn things in the first place.... only thing letting it cool down does it keep the bearings from coking on shutdown.... not lengthen the bearing life. water cool it.... or find another turbo

AFAIK cooling the turbo off after the engine has just been running allows the heat stored inside the turbine to exit. If you don't cool the turbine down the heat will transfer to the chra and damage the bearing system.

Re: gt28r...three quick questions (Si Shane)
Yea but its not the right way to do things.... running water lines keeps the chra at a certain temp, it wont let it fluctuate too much.... not running them allows chra temps to skyrocket to near exhaust gas temps... not good

1. you already have your answers. (WATER COOL IT thats way too much money to halfass it)
2. Majority of internal wastegates will have those types of issues with large exhaust. Go external.
3. depends on what you define as funky show us the pic of the one you are looking at.

yea,stock bottom end untill it blows..im hoping for around 230-240 at around 8-9 lbs
here is a picture of one...you can see where i would need a flange like piece to connect the charge piping to....i still would like to know about spiking issues with this turbo,if so, has anybody welded the flapper shut and ran an external wastegate?

Re: gt28r...three quick questions (second edition)
With the power your looking at why not get a non BB t-28 they still will support 270whp your engine should be ok with those power levels BTW. Tell you what I'll sell you mine ill include the intake pipe off my s14.

Re: gt28r...three quick questions (Churbo)
as usual..i agree with wantboost...and this question just keeps popping up.
i just dont understand the big problem with people and running the coolant lines.
i purchased a gt-series "install kit" from jeff evans, its all fittings and stainless lines, make the install very clean and has really no chance of causing any problems.
the only thing i can say is just keep an eye on your radiator overflow tank, as the high temperatures of the turbo seem to play some sort of role in "stealing" a little coolant

Re: gt28r...three quick questions (wantboost)
just to clear things up a bit:
1. Garrett only makes stainless steel BB chra's
2. water must be ran to radiate heat from the stainless bearings, as they have a very high expansion rate with tight tolerances.
3. your Garrett turbo's warranty is void if it is a BBchra and has been ran without water.
we've had 2 customers return their GT series that were ran without H20, and the result was a snapped shaft...
the water lines are very simple to run and can in most cases be t'd off of existing lines.
hope this helps
feel free to PM me with any questions

I thought Garrett does not warranty any turbo that are being used for racing/offroad purposes. When my GT28RS failed due to a bearing failure (it was watercooled of course), they simply told me they do not warranty anything unless the turbo was a factory turbo replacement. Well, we all know that Hondas never came with turbo, and no factory car ever came with a GT28RS. Can you shed some light on this? Thanks

I think there are gaskets that block the waste gate from opening which you could use... but im unsure, so make sure from one of these other guys
