t28 turbo

[creativepunka]

Hey i was wondering if a t28 off a R32 GTR would be too litle for a vtec d16y1 civic? i just think it will spool up nice and quick cause of its size.

It really depends how much power you want to achieve. A T28 on your 1.6 would proberly produce about 140rwkw at 1.0bar at best. The upside is the fact that you would have very quick spool up and great mid-range if that is what you are after. If power is what you want then a T4 might be better.

geez thats one hell of a turbo to produce power at the rear wheels :p

i think the T28 would be fine if you want a cheap street turbo, though i'd go for one of the garrett GT series as they are much better turbos (but will cost a lot more obviously)

Engine is still standard? I think it would be ok, and yes it would spool up quick, but on the other hand it would be spinning hard at higher rpm and therefore the turbo will run hotter. :D

I would recomend the T28 of an S15 (not R32) The S15 T28 is steel wheel and B.B.

I have a S15 T28 on my B20A prelude. U have very little lag and still a healthy whack of boost at top end. I feel it is a very good 'street car' turbo setup.

yer i can get the t28 for free because im swapping a mates gtr turbos over to hks2530s and said i can have em and the stock gtr intercooler(which is goin on my other car). what about a t25g off an sr20 silvia? cause im putting a to4 on a mates car and he said i can have that one too. its just that i can get the gtr one quicker. its just going on a stock engine and dont really care how much power i really make- i just wanna be able to beat a few commodores ;-)

As for a T28 from a S15 being Ball bearing- It is just a myth. The only Ball Bearing t28 turbo is from the high end imports (not sure if they call it the type S), all Australian delivered ones are bush bearing. Many will try to tell you it is BB but don't be fooled.

I was not talking about a 'gtr' I was refering to a 'r32 gts'


And I was tlking about 'type S' s15 turbos.



Sorry about my lack of communicatiom skills.

FastAzNice turbo, You got a spare for me, I am only using a S14 t28, does a great job but wouldn't mind a type s one or GT28.:D

[Weq]

flipmods is correct about the GTR turbo .

[poid]

flipmods GT28's arent that much anyway, $1200 will get you a brand new one ;)

The T28 from a R32 twin turbo will not work as efficient on its own since it is designed especially for a twin turbo sequential set-up, however thats not to say it wont work. If low boost, then go for it, but dont boost it too high due to the crappy ceremic turbine (ewww!). The T25G is alittle more laggy i have found but are smaller in size... not much grunt in the top end. But if ur getting them for free, then they'll do the job just fine.

[creativepunka]

well i got the gtr turbo here but i also got a r32 gtst ball bearing turbo which i have decided to use. I got it real cheap and its in mint condition. what are these turbos called? any pros/cons? so far its a bitch to get oil/water fittings.

[LuKeM]

for a 1.6 civic a t25 would be a much better bet...especially if your only looking at a low boost setup

i have a t25 on my pulsar...and its far LESS laggy than a t28 on the same car......i get full boost by 3000rpm...where the t28 gets full boost by 3500rpm.....

the t25 on my car is much quicker than the t28 on the same car if the boost on both turbos are the same......the reason why the t28 is better ( and that i will be getting one) is because it can handle much more boost than the t25

but i again if your only running a low boost high compression setup......t25 for sure!!

[poid]

i disagree, with the high comp the T28 is gonna spool quickly and will have much better top end. The T25 is too small IMO

When you talk about the boost on both turbos being the same, remember that at the same boost levels the T28 will actually be pumping more air into the engine than the T25 so will make more power. Boost refers to pressure and not the volume of air going in.

[LuKeM]

fair enough....i can only speak from my experience....that being that my t25 is quicker than the same car with a t28 at the same levels of boost

[poid]

what engine is that on though?

[LuKeM]

sr20....the t25 on my car is good for a 150kw atw

so my thought ( correct me if im wrong...im not to familiar with high compression and turbo) is that if a t28 is to big and laggy for a sr20 on only 10psi then it will definatly be to big and laggy for a 1.6 litre engine......if you are gonna boost it above 12psi then yeah go for the t28....if not then t25 is far more responsive

[poid]

dunno how its gonna be laggy on a 2L man, i've honestly never heard of anyone going from a T28 to a T25 on an SR20. On the S15's for example the turbo's are good for about 195-200kw at the wheels.

I have a GT28 on a 2.2L, and while its bigger displacement and a better turbo the fact that i see boost below 2000rpm suggests that on a 2L you'll be seeing boost very early in the rev range

[LuKeM]

gt28 is abit different to a t28...gotta love the spool up time on the GT series :D

all im saying is that if the guy isnt expecting to run more than say 9psi boost...then getting a t28 is useless....its not being used to its potential...its a bigger turbo than the t25 so therefore is laggier......and at 9psi the t25 will make the same peak power as the t28 on 9psi.....but will have less lag....so whats the point?

[creativepunka]

well iv done a pulsar and we went from t25 to t28 to to4 and now i no whAT extreem lag is lol. na t28 on the pulsar wasnt laggy when tuned.

[Weq]

engines have different efficencys and this conributes to lag... t28 on a b16, no dooubt.

That post doesnt make much sense to me. The T28 on a S15 runs only 7psi boost standard, and with an exhaust upgrade alone can get plenty of power to the wheels. Even jacking the boost up to 11psi, you cant even feel the boost kick in, lag-less.
From experience, the smaller T25 from a S13 has more lag, even though its a smaller turbo, but runs out of puff very quickly in the top end. It kicks in hard, but dont be fooled. To me its a cheap and nasty turbo, but not worth the effort!

GTRs uses T28 turbos, but different spec to say S14-15 T28s. GTST use T04 (not turbonetics) which are slightly bigger then the GTR turbos, this may be what ur referring to.

The JDM Spec R uses ball bearing T28s, as to the JDM S14 series 2. Its inconclusive to say that all AUSDM S15 had bush bearing T28s. I know this because when I had my S15, the product code on my T28 refered to a ball bearing unit on the Garrett catelog.

[poid]

i think the last of the S15's brought in had the ball-bearing turbos, but earlier ones didnt (except perhaps the odd wierd one)

dude.....again i can only speak from experience.....FROM experience my t25 is quicker than a t28 on the same car up untill 12psi ( anything above that the t25 is hopeless and runs out of puff....where the t28 can be pushed to 18psi no probs)
in my car the t25 comes on full boost a whole 500-800 rpm quicker than a t28

trust me ive tried and tested it......but this is in a pulsar....as for a civic i really dont know as ive never seen this comparrison

:thumbsup: no worries champ...


ive had the exact same experience with the T25G.. kicks in hard but runs outta puff at the top.
