t25 to 14b

[peter535]

ok so im gonna change my t25 to a 14b beceause i have one lying around so i was reading that u need a install kit is it the same install kit as a 16g install kit?

 

[xioca]

yes.

 

[97 4G63]

Yes it's the same one you can get it at extremepsi.com thats were i got mine.

 

[peter535]

does anyone have a link to where i can find instructions on replacing my turbo

Try this link or VFAQ.

k thanks for the link but is it the same for a 14b?

Here you go this shoud be all you need. ITs a pretty much straight forward install.

PS.. I would just buy the install kit and but if you on a budget this works very well.

The 14b is just marginally able to handle a bit more boost than a t25 and it spools slower. If you are going to go thru the work of installing a new/different turbo why not invest your hard work time in a bigger badder turbo? There are a myriad of options and some can be had for a very low price.

Like a brand spankin' new Evo III 16G. Seriously.

If he has a 14b he might as well swap it in then focus on his supporting mods. Then he can go for a larger mitsu turbo and have all the lines and j-pipe. It's not like it's hard to do a turbo swap, as long as he uses anti-seize putting that 14b in.

 

[peter535]

i got my 14b for free and i wanna save up money to get a bigger turbo injectors dsmlink and a better clutch so in the meantime i can have something a lil faster than a t25 i read reviews than u can boost it to 18 19 psi thats allot better than the t25 and its only gonna cost me the install kit

 

[spooled_u_1st]

Yes definately install the 14b. Keep installing supporting mods and then maybe jump to 50 trim.

No, seriously though.
the 14B is a suprisingly capable little turbo. cheap, snappy and an easy install WITHOUT having to buy an install kit. if you get a good used turbo, reuse your stock water lines and oil drain, buy a RRE oil feed, hopefully it came with the stock j-pipe, some new gaskets and your done! i think my 14B install cost somewhere around...$65? 55 for oil feed and $10 for a gasket set.
I'll tell you what, I love boosting past my stock turbo buddys and reminding them that "its JUST a 14B, remember?

as for the real reason as to why go with it?
simple.

its cheap.
its easy.
and your stock fuel system can still handle it.
not to mention it makes right around 100 more CFM.


so quick summary.

A bit more boost eh? I think that holding 20psi to redline and flowing 100cfm more than a T-too tiny is a good upgrade, considering it is free. If you don't know what you are talking about, then GTFO. Quit posting false and ignorant posts.
OP: In my PERSONAL opinion, the 14B was a great upgrade from the T-25. I see 15psi at ~3000rpms, which doesn't bother me since I'm fwd and the slower spool helps with traction. But once it hits, it continues all the way to redline, and it pulls alot stronger than the T25 ever thought of. The swap wasn't too bad, took a few hours, but I also was running around to different part stores getting stuff for the swap. I reused one of the coolant lines off the T25 and used my 1G oil drain line and the factory J-pipe. I ordered a ss braided line to go from the oil housing to the banjo fitting on the turbo. I would not use the factory line, as I had to bend mine, and wound up kinking one end, and breaking the other end. That set me back a few days waiting for the ss line to show up.

Not to thread jack or anything, but I was just going to ask a question pertaining to the last post.

So it is normal for the 14b to spool later than the t25? I was becoming erked at the fact it was dumping in at between 3 and 3500 instead of the 2500 to 3000 that I was used to.

The nice thing about the 14b swap though, is with the 14, when I say dumping in, I mean DUMPING in. And it pulls so much harder up to redline. DEFINITELY worth the money I spent on the swap.

Yes, as the 14B has a larger turbine than the T-25. But it makes up for it in the top end. I was reading somewhere that its not turbo itself that cannot boost past 12psi at redline, its the actuator. I think it was RRE that did the article, as they were saying that the spring in the actuator is too weak to hold anything past 12psi.

thats why you, port, port, port!
I flared my Turbine inlet to match an evo manifold and gasket.
ported the 2g o2 sensor housing to MAX tolerances. 2.5mm thickness at every place i could measure.
plus i ported the outlet of the turbo to match the o2 inlet. also flared the 14B wastgate outlet to the bell shape that matches the Upper o2 inlet.
it was a lot of work but SO WORTH IT.
I get full spool at 16-17psi at right around 3200! its so AWESOME!

I'll tell you what, I don't think I even want a 16g with as good as I have this little guy running!

P.S. the stock WGA is regulated at around 9-11 psi. with your stock BCS it is around 13-14.
use a MBC or EBC for higher pressures

No. I've seen 14b actuators hold up to the turbine housing pressure required for 15+ psi of boost. I'm sure that a wore out actator spring could very well crap out. But, a good working 14b actuator has take me to over 22 psi on my small 16g.

I have a 7 cm^2 turbine housing, but I doubt there's enough difference to blow open the 14b wastegate in the 6 cm^2 housing until you're running higher VE at higher rpms (SMIM and/or cams).

That leads me to a good point about the 14b. Upgrading the 14b and really getting the most out of it is rather easy after you swap to it. All you need to do to REALLY wring it out is later upgrade to a 7 cm^2 turbine housing, and you'll be capable of flowing anything that 14b compressor can throw at you. Used 7cm^2 housings go for 50-75 bones all the time.

You have 100 more hp potential w/ that 14b over the t25. It's not the flow that's marginally better; its the slower spool that's marginally worse.

Using the 1g exhuast manifold and 14b seal ring will give you that smooth transition from the exhuast mani to the turbine housing and you'll not lose that exhaust gas velocity so neccesary for spool and good flow. Thus similar results w/out all that hard work.

But if you plan on running the evo3 exhaust mani, then it is definately a good idea to port the turbine housing. A better option to get larger ports and more durability would have been to run a 2g exhuast mani. It has the same diameter runners. and has a smaller exit to the turbo. This leads to less porting and less flaring which will increase volume and slow down gas velocities.

But an evo3 exhuast mani is a great aset to a 16g turbo. So having one now will be good for your 16g upgrade. Just get the seal ring and don't spend the hours porting. In fact If you decide to run a 16g/evo3 mani combination, you can cut a piece of 2 inch galvanized steel plumbing pipe to the correct length, and it will have the proper diamter to fit right in there in place of a seal ring. It will also have a thicker wall that will yield a smoother transition for the exhaust mani to seal ring and then seal ring to turbine housing. The stock seal ring is thinner and doesn't allow for as quite a smooth transition.

Sorry, I should have been more specific. I was actually talking about the T25 actuator, not the 14B. Trust me, I too have seen over 20psi on the 14B, ! (installed MBC backwards, will not do that again. Etched direction arrows with my dremel in the side of the MBC to prevent that from happening again.)

Ah! that makes more sense.

now you can brag about taking your 14b to 20 psi .
