Garrett T28

[locote]

What sort of power are ppl acheving in hondas with these turbos.
i reacon they are a great all round turbo, 350hp is achieveble on sr20's
can same be said for a b18, with the right compresion?

[joyride]

u talking about the s15 T28?
see my sig below, i was (reason: sold car yesterday) running one on a 1.6L toyota

[ProECU]

Dont expect to make the same power as the sr20's as those motors have larger displacement to begin with.

I'd expect to hit around 220-250whp on a B18 at around 8-10psi

The same turbo on a B16 will make around 200-220whp @ 10psi

[10KRPM]

These turbos max power is about 280-300hp.

Max boost they can run is around 17psi......and thats at the limit.

[locote]

i only ran 12psi on my s15 and made 280rwhp,
but it was tuned,
id run 6-7 psi on low boost every day driing, and use max boost at drags or ______.

yeah u guys know when. ha ha

i was told by the tuner t28s will happyly run 18psi, but they arent as efficient.
would u recomend a bb turbo?
i was thinking maybe buy a used t25 of a u12 u13 bluebird and highflow that my mate did that and was pulling 320fwhp on 14psi on a u13 sr20det.
turbo can easyly do 24psi but his injectors and intercooler werent large enough,
only cost him 800buks to get turbo rebuilt and t25's are cheap as chips, they just a bit laggy, but on a non lsd fwdr might work to ur advantage.

thats wat i think.

please correct me if m wrong

[russs]

the t28 is a good turbo. it will one day be in place of my t25 on my sr20....

make sure u get the s15 bb t28. the gtir t28 i would get, as it is a simpler bolt on than the s15 t28. As i think u may need to turn the compressor cover the other direction to suit front wheel drive cars...

[alta'd n13]

a t28 is a good choice of turbo and can run up to 18psi+.
as russ has stated though the s15bb version of the t28 would require rotation to suit a fwd application unlike the GTi-R version of the same turbo.
the only thing is that the t28 will give the same result as the t25 more or less and you won't reap the rewards of the t28 over the t25 until in excess of 12psi of boost.
if you are planning on running less than or at 12psi i would recommend just going for the t25 as its a cheaper alternative and will give the same result more or less

[locote]

so a U12/13 t25 would suit my b18b and have the compressor facing the right way( driver side)??? and just get it highflowed later on

[ProECU]

Dont mean to sound arrogant here, but do yourself a favour and step up to a T3.

The spool will come in a little later, however you will be making better power at redline, and your fuel economy will not suffer due to a very early spool.

[locote]

theres lots of t3's out there, i have seen so many of then with different a/r ,
what a/r would suit a b18b enought to flow over 300hp at front wheels,

[ProECU]

the super 60

[GSI-PSI]

or even better, get the higher powered gt28r with the bigger mouth cos it will spool up quick and have awesome top end aswell

[locote]

gsi-psi would you be able to show me some photos of under your bonnet???
wanna c wat ur set up looks like

just a little teaser.

Ud probably want to run a larger .82 A/R though for a DOHC vtec.

[locote]

wat turbo is that mate??

[Weq]

gt2871r .63 a/r with t3 exhaust housing

[LVNIT]

gt2871r .63 a/r with t3 exhaust housing

You got it..? :D

[GSI-PSI]

thats exactly the turbo im talkin about.

[locote]

post some photos GSI PSi

[Weq]

You got it..? :D

yep. she is off getting some cooler piping done atm. If u want some cooler piping for ur setup, PM me for details.. Ive got a pretty sweet deal happening. it will be a boltin kit, aluminium.

[GSI-PSI]

Well here are a few pictures of my turbo and log manifold as requested.

sweet

[superR]

which is the better turbo for a b18c turbo coversion the T3 or the GTiR T28....im prettey sure that they are both bush bearing? or can you get bb t3's

[saxman]

oh can I play too?

hmm interesting studless manifold setup. what are the advanatges of that??? :P

[saxman]

I'll see your big ass turbo and raise you a one off carbon intake plenum to feed boost through cbr 954rr itbs AND a really dorky little skateboard

saxman ....you must have one rad tuner. Quad throttle bodies + turbo + god knows what else.

I am my own tuner... I wouldn't let anyone else touch my engine

[superR]

wish i knew how to do it all......... woulda saved me a shit load....... what sorta power output you getting?

[Lyle_Style]

Just spend a little more and get a GT30 R for like 1300

[saxman]

wish i knew how to do it all......... woulda saved me a shit load....... what sorta power output you getting?
new turbo set up is still in the works... need to sort some stuff out on the downpipe and then I'm off. Realistically looking at about 220-230whp... mind you this is on a stock internalled D16z6. I was making about 190whp on the old turbo set up on this engine... going for something now with a power delivery more like an n/a engine

[locote]

saxman what do you think of these ebay kits like ssautochrome, i heard their only weak point is their turbo manifolds are to weak and need strengthning, any thing else that you heard??
cause apparently ythey sell like hot cakes!

they are BY FAR the absolute biggest pieces of shit ever to be created.

the manifolds crack... a lot... sometimes with parts just falling off... due to way too thin of metal and using different materials for the flanges and runners.

the turbos are rarely balanced and some have just split in half

the downpipes are generally 2"... despite being advertsided as 2.5"

the wastegates very very very rarely come with the spring that they're advertsided as coming with, and the diaphrams on them are known for breaking after minimal use

there's question about how well the intercoolers flow

so basically, if you're lucky enough to not have the manifold fall apart on you(I'm not talking about prolonged use... I mean people have these things fall apart after half an hour of use), you some how get a turbo that's balanced correctly and doesn't blow the seals after the first use, and you can deal with having WAY too small of a downpipe, you run the risk of the wastegate overboosting suddently(assuming it boosted to where you want in the first place) and blowing your engine.



the moral of the story? They sell utter shit for a cheap price, so lots of people buy them thinking "nah, it won't happen to me"... and then it does... long after they've already left good feedback on ebay.

DO NOT, for ANY REASON, purchase a turbo kit(individual parts or a kit) by the likes of ssautochrome, stone mountain racing, obx, xs power, or anything that resembles there parts.

[locote]

ok. thats what i wanted to hear:)
thanks
what you think of the REV HARD kits??
these are like 5 times more expencive than ssautochrome

[saxman]

don't go off the ssac for prices on turbo kits... compare similar ones.

revhard isn't bad, but like all turbo kits, you're going to want to get some sort of engine management on top of what you get. personally, I'm a big fan of the put a kit together yourself following.

[alta'd n13]

yeh definitely worth putting something together yourself. that way you get all components to exactly what you want for your requirements and you wont need to upgrade anything until you get more boost hungry or something of that sort.
get a custom made steam pipe manifold to ensure no problems with manifold cracking unless bad workmanship is involved.
also try and get a turbo flange suited to probably a nissan t25 type flange as there is a very large array of aftermarket bolt on turbo upgrade options available for this flange unlike other flanges from other manufacturers which will require adapting for future upgrade.
the main point though if not already done is to prepare the car for boost before it actually has it eg: brake upgrades, tyre upgrades for traction, suspesion sorted out etc etc. i know this seems pretty obvious but it is a major factor that alot of people tend to neglect.

is this manifold any good???
i can get a garrett gt28R for 1100$$ new from a shop here in perth is that a good start??

[alta'd n13]

i realise ebay is a good source for bargain performance parts but personally i wouldnt recommend buying things such a turbo's through there. better to inspect in person when it comes to turbo's especially.

im interested in what sort of boost you are looking to run and what sort of power you are looking to achieve because that turbo is a relatively large item for a front wheel application

[alta'd n13]

also in reguards to that manifold it only specifys a 100hp gain which will equate to something like 60ish kw. the gt28r will be too big of a turbo for that manifold and i would say it would be prone to crack on big boost from a turbine such as that.
best bet if you wanted to run a large turbo of that nature is to (like i said) get a custom steam pipe manifold made for you to ensure quality of manufacture

best bet would be to get some prices from the site sponsors or advertisers as they would be a bit more reputable than alot of the ebay dealers

[locote]

well im chasing 300+ fwhp eventualy.
id be running minimal boost on turbo till i get management and rebuild motor.
looking at 8.5 comp ratio forged pistons, stronger conrods, pos metal head gasket.
ive got a set of stage 2 crower cams and cam gears and springs and retainers on the way. and looking at tunning with link EMS or wolf.

that manifold is crap

[alta'd n13]

i would personally recommend a stinger ems management for your requirements.

if you are looking for 300fwhp you will be in the 150-200 fwkw quota.

for this requirement i would recommend the custom manifold, first and foremost you want something that is going to perform before it looks pretty. if you wish you can get something polished afterwards but imo steampipe with a nice HPC coating will suit your requirements better.
for a first stage i woul say to you to go for just a t25 turbo froma u12 or u13 sr20det engine as it will suit the front wheel manifold setup alot easier and will require less modification. the t25 is a very good all round compressor and will get you on boost with minimal lag on your early stages. the t25 can push a pretty easy 12psi out of it and is good for a pretty easy 150fwkw on a sr20det engine setup which would normally push around the 75fwkw in n/a form.
if later after your rebuild you require more boost an easy swap to a t28 will require no further dump pipe or turbo flange modification. the t28 will only really be useful to you over the t25 once it surpasses the 12-15psi mark so on your factory internals will not be of any use to you and will only create a bit more laggy response on your early setup.
i feel the t25 will get you to your goal with very little difficulty or if not a normal t25 try and get your hands on a gt25 which would be also an excellent turbo in this situation.

hope this helps you out mate. any further info dont hesitate to ask

[locote]

i know a high flowed t25 can do the job, but they lag too much.
my mate got 320fwhp on his n14 with a u12 sr20det.
but he lags all the way to 4000rpm

[EGB16A]

forget a t25....
if you must, get the t28.... but take pro-ecu's advice and step up to a t3.

[alta'd n13]

i cant see how a t25 would lag on a u12 sr20 running that much boost. the only reason it would be lagging is due to the high flow. going with a bigger compressor such as a t28 or t3 is only going to make the problem worse.
what size cooler plumbing was he running on the sr? must have been around 3inch plumbing or with an extremely large cooler core creating the lag not the turbo itself

[EGB16A]

check out the bang for buck thread (sticky at the top of forced induction thread).

It has recomended turbos for various budgets. none of wich are t25s

[locote]

2.5 inch plumbing, stock u12 cooler front mounted but. he could only run 14psi max due to injecors maxing out made 320fwhp,
lagged as in didnt hit 14psi till 4000rpm but started making boost at 2500-3000rpm

the gt28r looks like a much better turbo than t3 at a cheaper price as it is in special atm, t3 is like 1900 to 2200 new, they got a couple of gt28s for 1100 they are normaly over 2gs!!
all i need is a manifold that wont break.
i was thinking of just getting a cast iron 1, but who sells cast iron b18 manifolds here in aus??
i know i can gett 1 from ebay for like 500 but its from the usa, but its cast iron last a life time

[saxman]

that manifold is an ss autochrome manifold. They may not be saying it is, but any manifold that looks like that is ssac in one form or another.

a t25 will not lag by any means on a b18... you're looking at full boost at like 2500... You can't really compare how a turbo performs on a similar displacement engine meant for a turbo, as there are a lot of other variations to consider. Typically, an upgrade turbo for a nissan engine would be a good starting turbo for a honda. the gt28r isn't a bad turbo, but I would go for a gt28rs if at all possible. It is a much better turbo. T3's aren't going to lag much either. I've set up several b16a's with t3 60 trim .42 .48 turbos, and they're seeing full boost(9-10 psi) around 2800-3000 rpm.
If you buy from the states, T3's can be had for quite cheap. There is a seller on ebay "down2turbo" that sells freshly rebuilt t3's using brand new garret center sections. They work great and are quite cheap. They can be had for about $375 US. I've personally purchased about 10 of them from him for different cars, so I have plenty of personal experience with them. I also have one for my car.
