I wanna this to be streetable so don't tell me to get a T3T4.
So which one would you pick and why? On the same motor B20 with pertect tunning with hondata.

* which whould spool quicker?
* which is capable of more power?
* which will last longer (if both driven the same)
* what are the possile up grade to both of them? ex: t3----up to a t4?
* which has more top end?

 

ttttttttttt

 

why would a t3/t4 not be streetable?

 

what type of turbo is the 18G? T25 or T28 or non of those? i'm not turbo smart. i know that T25 is stock turbos and T28 is better than T25 and are very good for street

 

18G is the biggest of the lot. It would be real good for a B20 but if you got one of those BB T28's that would be pure sweetness!

 

18g /w TD05h(like greddy) housing is probably bigger. It spools quick and has good top end. If your planning 400+ hp, dont get any of these. Get a t3/4 or bigger.

I might sell my mainfold and turbo, if you intrested. I don't know how much I want to sell it for though, quote me a price.

 

how about comparing the 15g to the T25.. which is the best of those 2?

 

those are both small turbos..i wouldnt chose neither if u wanna make anywhere near 400hp..

this thread is weird to me..i always thought t3/t4 was the "streetable" turbo and a t4 is when it starts to get "unstreetable"..differnt folks, differen strokes

 

The 15g is the same turbo that comes with Greddy's D16 kit, it's bigger then T25. The T25 is same turbo on 2g DSM's, and I know the 1g DSM turbos are bigger. AKA 14g.

 

The 18g is made by Mitsubishi, I would say a little larger then a Garret T3.

Put one side by side, the 18g with Td05h housing looks as big T3/T4, but of course performs very diffrent.

You are right, but keep in mind the "smaller" Mistu turbos like the TD05-14B, TD05-18G, TD05-16G etc are going to have more low end oomph since the Mitubishi motors are not the same as a high-revving Honda engine. I think the 16G is a damn good choice for an SOHC!

Although, once you look at the price places charge for them I think you'd be more interested in a small T3.

naw, i think the 1st gen dsm turbos, the td05-14b, are smaller than the t25. you want the 1st-gen td05-16g's, those are bigger than the t25.

 

T25's are smaller, I compare the two already. Goto homemadeturbo.com they so too.

damn know one seems to answer all of my questions... hauuuunnn. please read my questions over.

 

1. The t28, because it is way smaller
2. The 18g, larger turbo
3. Depends on how much you are pushing the turbo, i think since the t28 is smaller you will max it out sooner, so the 18g will be harder to max out of the two.
4. i think you will have to get another turbo, there are not many upgrades, but not sure on this one.
5. the 18g will have more top end on higher boost.

Summary, if theses are your two choices, get the 18g, the t28, i think personally is two small for your motor.

hope that helps

thanks for the reply ..... anyone else

 

20g would be much better, cost nearly the same as an 18g.

 

20G is pretty hefty.

14B is WAY better (bigger) than a T25. The DSM guys with T25s don't swap 14Bs on there to get a smaller turbo.

 

in terms of size and flow (from smallest to biggest)

1) T25 (2g dsm turbo)
2) 14B (1g dsm turbo)
3) 15G (greddy d16 turbo)
4) 16G (Mitsu EVO turbo... i think it might be the big 16g... not sure)
5) 18G (greddy dohc kits)
6) 20G
not quite sure where the T28 fits in though... i think it might flow more than a 14b... not sure.

EDIT: out of the turbos in the topic title... 18G would be better

I've been doing search on the T28... not that much info but some one did say alot about it coming off a s14-s15 and the pulsar sir. They said somthing about the T28 making more than 320hp can someone verify if this is true or not?

 

Ok guys the T28 which is a modified T25 mitsu turbo looks just like a stock T25 on the outside the only difference is that the inside has been modified with some porting and different wheel sizes...
And this turbo has propelled by friends 99 full weight gsx to a 12.2 @ 114mph at 21psi and 110 octane which in all probability means that he is pushing somewhere in the range of 350-400 whp..

I would go ahead and say that this is a very good turbo for your application, as fahr as spool up his starts at about 2500 or so...

I will continue with the 18g next... stay tuned..this post will be updated

That's true. You can find t28's from JDM Sylvia's SR20DET. As for HP, I believe a blacktop S15 SR20DET pushes 247hp stock.

BUT, do not mistaken the t28 as the same turbo family as the DSM's t25. They are not compatible, meaning the t28 won't bolt up to the same manifold.

ForcedPerformance.com has a turbo that might look pretty good for your goals. They take a stock t25 from a 2G DSM and rebuild it with FP spec internals to come up with the FPBig28. It's good for 11's on a FULL WEIGHT 99 GSX, so that says alot about this turbo's potential.

BTW, a 14B is bigger than a t25.

 

tttt

are you sure that you i can use the hks manifold for the T28? I swear someone on this form said that it would work without any mods.

 

i think the T-28 uses the same turbine flange as the T-25. if it is, then the T-25/T-28 will work with the HKS manifold. The thing is... the DSM T-25 won't fit the HKS manifold. the HKS manifold is a standard T-25 flange (rectangular). The DSM T-25 uses a Mitsubishi flange (circular).

 

Well I really don't know what the HKS manifold flange looks like so here is a picture of the turbo exhaust flange from Forcedperformance's website...
