14B vrs. T-25
 

What are the differences between the two? Thanks!

Re:14B vrs. T-25
 

14b is bigger but there both too small to make any good power.

Re:14B vrs. T-25
 

OK. As far as installation and stuff are they the same though. I know the 14b has the flange going to the charge pipes but are there any other physical differences. Thanks!

Also sorry for posting in the wrong place the first time. I was in the chatter fourm and that question just sort of popped up so I posted.

Re:14B vrs. T-25
 

flanges are different.

Re:14B vrs. T-25
 

the exhaust housings are identical between the two, so the turbine inlet and outlet flanges are the same

Re:14B vrs. T-25
 

Difference: 14b is good for a 1.5 or 1.6 (----, we've even put em on a H22VTEC & H23 Non-Vtec)... T-25 is good for a 1.2 or 1.3 litter motor (like a suzuki or geo metro) DO NOT USE 1 T-25 ON A HONDA!

Re:14B vrs. T-25
 

OK. I geuss a better way of putting my question would be. I have been planning on using a t-25 in my setup. What if any differences would there be in things I would need if i switched to the 14b as it seems like a better option.

Re:14B vrs. T-25
 

I dont know, ive got a t25?? I mean it was used on a DSM 2.0??? So why not? i think its a good turbo to start with, plus most parts fit the 16G for future upgrades right???

Re:14B vrs. T-25
 

Here is a good link for picking a turbo for your engine, although it does use the T25 for any 1600. I'm sure that will raise a stink with some folks....

Re:14B vrs. T-25
 

OK pretty much what I'm trying to ask is weather there will be a problem if I've already orderd parts with a t-25 in mind (adaptor plate, oil lines), if I instead decide to use a 14b since I found someone who will give one to me for probley 20 bucks. Sorry for not being to clear on this one. But thanks for the replies they sort of convinced me that that is what I wanted anyways.

Re:14B vrs. T-25
 

could someone also compare the 15b to the others?

Re:14B vrs. T-25
 

power drops after 6krpm w/t25

Re:14B vrs. T-25
 

sounds like you're going tho use the t25 any way so just go for it. It's not gonna make huge power but it will work.

Re:14B vrs. T-25
 

on a d-series, power doesnt drop off with a t25. if you want a very fast spooling turbo that can hold moderate boost levels, the t25 is a very nice choice. i personally dont understand why people are so in love with huge turbos. instead of making your power curve smoother and broader, it seems like people are wanting something more like a vtec multiplier. i guess its preference

if you switch from a t25 to a 14b, i think you need to change the oil feed... but im pretty unsure of that. you would also need to change the piping going from the compressor to the ic, as they have different outlets

Re:14B vrs. T-25
 

Yeah I'm just pieceing a kit togeather now so its not like I would have to change much. I may as well do the t-25 though. It seems to me as if their a little less available but thats ok. I'm only gonna do 8psi on a stock d16 so big power has never been the goal so turbo size isn't a huge concern to me. I'll just keep on the lookout for a deal on a t-25. Or just go steal the one from the ricer elicpse that goes racing by my dorm every night. ;D

Re:14B vrs. T-25
 

either turbo would work good on a stock internal'd d series. the oil and coolant lines should work good on either turbo as they both use banjo bolts for connections. you may have to bend the lines slightly if anything.

and who says the 14b can't make good power? i've seen it make over 300whp and run the 1/4 mile as fast as 11.7 seconds.... i wouldn't call that exactly slow.

Re:14B vrs. T-25
 

I've try them both. First the t25, after 14b on my b18b. The T25 spool soooo fast. On the Highway, at 60mph, the boost is instant like -12, bang, 6psi(my t25 was set at 6psi). Full boost at 2200rpm...a lot of tire spinning at the spot light. On a rainy day...omg! But at the drag strip, after 5500rpm the power go down.
14b: Slower spool, like 3500-3800(I dont really check it). On the highway, in 5gear you need to go to 120 to begin to feel the rush. I dont feel any lost of power at rpm.

Verdict: On the street the t25 is a beast. The 14b is better for maximum power(versus the t25, we are not talking about t3/t4 here...). If I would redo it...hmmm very hard question...if you like to downshift and like rev...14b..if you like low-end torque..t-25.

Re:14B vrs. T-25
 

I do like to rev, but quick street power is really the most important to me. T-25 it is. And also I think the Oil outlet for the t-25 and 14b might be different. From what i can tell from some reserch i've done one has a 44mm bolt spacing and the other has a 38mm. I didn't quite understand the thing though so i might be wrong

Re:14B vrs. T-25
 

ive got a t25 on my d15b2 and love it.. i seem to boost later than most, i hit 8 psi closer to 3500 rpm.. but its still a very good turbo

Re:14B vrs. T-25
 

I know the oil return for my T25 was 44mm. I just ordered some nice lines from stealthmode. ;D

Re:14B vrs. T-25
 

So what about the 15g turbo they put in the new z6 greddy kit?

Re:14B vrs. T-25
 

the 15g (and the 13g, in fact) are for high flow and low boost. because the 15g is bigger than both the t25 and the 14b, it will spool slower.

Re:14B vrs. T-25
 

I would never get a t25. Good for quick spooling but can't hold the power in the top end. I quess you could say its good for starting out but you'll be wanting something better trust me

Re:14B vrs. T-25
 

T25's are considered t2 small for a reason.I ran a t25 as my first turbo on my old crx.It spooled quick but seemed to lose power quickly.Since my crx was auto i chose the perfect cheap turbo.A fully ported and clipped 13g out of a auto 1g dsm.I ran 1 bar and whupped some ass. ;D

Re:14B vrs. T-25
 

The new greddy 15G ( and the 13G in fact ) are TD04 turbos, and will spool faster than a 14B... The 14B is ( of course ) a TD05 turbo.. The TD05H-14B is the turbo outta group meantioned that can support the most power...

The greddy TD04-15G is VERY small !! The inlets and outlets are just pitiful... The wheel is "bigger" than my WRX TD04L-13T, but the WRX turbo can walk all over the SOhc greddy turbos...

There is more to a turbo than its compressor wheels size, the housings are a big factor too...

As for the question about the T-25... I say rock the T-25 !! It'll be so much fun driving around with quick and almost instant boost, but after you get "owned" by a lot of other cars that you "think you should beat", you can switch over to the 14B and kick there ass ( but you'll always remember the good ole days, when torque was just a 16% throttle away )..

TD04L-13T is the best mid-ground IMO... 10psi+ at 2700rpms and not even a hint of power failing off... The 2.0L WRX runs it at 14ish PSI, so you know its just chill'n on a 1.6L sohc civic making 10psi ( in my case ).

My 3.0L stealth is getting 2 TD05H-14bs ( 1.5L times 2 ).

Re:14B vrs. T-25
 

at what gear do you get the 10psi at 2700rpm? i'm getting it at 4300rpm also using a wrx turbo.

just curious, my downpipe might be wrong or the wastegate.

Re:14B vrs. T-25
 

2nd gear... I gotta keep my eyes on the road during first, or I'd prob. be parting out a wrecked turbo civic, hehe.

4300rpms is WAY !!! WAY !!! too slow of a spool for a wrx turbo !!! I have a 2.25'' DP, stock 1.5'' cat-back, AND 8.4/1 compression !!! And I still get lightning fast spool !! Sounds like your wastegate isn't quite sitting on the turbine housings...

Also...The WRX turbo is a little hard to work with as far as mounting, hehe...

Re:14B vrs. T-25
 

yup i have the wastegate pulled hard already, have a 2.5" downpipe also :(

whats your boost with just the wastegate and no controller? I only get 6.

as for the mounting, yes, its very hard to fit it in :(
