14b Is Installed, my thoughts.

[98TsiAWD]

I just installed a ported exhaust manny/ported 14b with 34mm wastegate mod.
DONOT try to file the holes on the oil drainpipe with it on the car like the VFAQ says, this will take you 6-8 hours
Just drain your oil and pull it off the car, and use a dremel to grind the holes closer, this took me about 10 minutes. The drainpipe was the hardest thing to install, hard to get the bolts in because the pipe needed to be bent/twisted a little bit to fit.

The RRE lower IC pipe for a 14b (the L shaped one) is about 3-4 inches TOO SHORT, so you will need a 6" rubber coupling to connect it to the
SMIC.

For the Water feed line, you will need about a 8-9" piece of 3/8" rubber hose, the stock one wont reach anymore.
This is if you use the drain one as the feed, and the feed line as the drain like the RRE hacker/tweaker kit VFAQ.

Those are pretty much the only problems I had with the install that I didnt already account for.
Make sure you have new crush washers for the oil/water lines.

The spoolup SUCKS, Its only ~500 rpms slower, but its still irritating.
But topend is WAY better than the T2smalls.
Overall the 14b is not really worth it, but this way Im ready for a 16g to swap right in. Dont get me wrong, the 14b is WAY better than the T2small, I need to install my 190lph fuel pump and turn the boost up to 16psi, then see what this 14b can do.

Fakin' turn it up dude =)

Oh man, you are going to hate that 16g.

I've never hear anyone say that about a 14b.

Well modded 14b cars are about as much fun as one could have.

I installed my 14b too. I also ported my mani and o2 along with the turbo. Why didn't you just take the die grinder that you used for porting and widen the holes in the oil return. Took me like 5 mins. I agree that it was a PITA to get the oil return to bolt up, thats probably the longest part of the install. But the sucky thing is, my turbo was blown, it showed no exterior signs of being blown, but it is. I sent it back yesterday and my replacement is coming today. I can't wait to feel the difference.

Finally someone agrees with me.

I've done the same swap, T25 for the 14b, what a waste of time, effort, and money.

 

[fastalon]

yea proberly casue u guys didnt have the supporting mods to get the full potinial out of the 14b....like 3 inch exhaust....255 fuel pump and afc..and 20 psi....so b4 u knock the 14b try that...then u will see a big differance...

"I need to install my 190lph fuel pump and turn the boost up to 16psi, then see what this 14b can do."

That says it all right there. Do you know what the difference was between my stock fuel pump and the 255 im running right now? About 3 seconds in the 1/4 mile. Seriously.

 

[Vinnie]

Take a look at my Mods, I have all the bolt ons someone can have including 3" exaust and fuel pump, still not impressive.

I'm not here putting the 14b down, I'm just saying it's a waste of an upgrade, save your money and get a better turbo, plus, by upgrading to a 14b, you don't really know the condition it's on, the turbo is tired and old, I'm just saying it's not worth it, just my thoughts.

 

[Vegas Smith]

Actually it was about 2-2.5 seconds.

I agree, since you are swapping turbos you might as well go with a 16g.

Yeah I know, I need to get DSMlink ASAP, install the Fuel pump and crank it up to 18-20 psi on 92 pump and see how I feel about it then. I hope I like it because I dont plan on modding this 98 any further than that.

 

[98TsiAWD]

Im not hitting full boost until 3400 rpms, is something wrong? The turbo/exhaust manny is ported, 34mm wastegate valve, and a 3" o2 elim. turboback.

 

[nine5raptor]

I start to boost at 1900 and am at 16 before 3k with stock 2g mani, stock downpipe, unported, unclipped 14b, stock wastegate valve, 1g 02 housing (unported).

intake is knn>gm 3.5"mas>brode intake

 

[loreak]

your not even running decent boost, turn it up to 18ish or run it at 20 at the track with racegas and it is very nice

if you think that was a crappy upgrade going from a t25 to a 14b then your going to think going from a 14b to a 16g is horrible, cuz its not that big of a difference.....

it would be like buying a 20g and running 10psi and saying oh this 20g sucks, its not that big of a difference, run it how it should be run and with what it needs to have, then say you dont like it

 

[1994supertalon]

You can go plenty fast on a 14b. Here is a video of a 14b powered 2g running [email protected]

[twenty5psi]

i thought the efficiency of a 14b runs out around 17 lbs of boost?..unless you have other cooling mods then anything over that would be over kill wouldnt it?..whats the efficiency on a big16g?..

 

[pneumo]

FYI a 14b should spool up at 2700 to 2800. When my car was set up with the full porting, full 3" exhaust, and free mods I got it to spool at 2500 in fourth gear. Then I went 12.8 @ 106.5 mph.

So something is wrong with you car. I would suspect a boost leak somewhere, or maybe the turbo wasn't in very good shape.

 

[cucumber]

14B is a great upgrade. I wonder about the ones who have a qualm with it, is it user error?

Think about what your T-25 flows. A measely 300 CFM's. Give or take a few. The 14B flows 400 CFM's or more. The numbers differ everywhere I look. That's alot more power guys. I don't understand why you'd think it's a worthless upgrade. I did mine, and had it put in for less than 50 bucks.

In 2nd I dont hit full boost of a wopping 14psi until ~3300 rpms, in 3rd I hit full boost at 2900 rpms, wtf is it different.
I also notice if I am going 30mph in 3rd and hit it until full boost hits and then it falls off to about 11psi shortly after. But it will hold 14-15psi all the way to redline if I hit it from 30mph in 2nd. Is it just because Im in too high of a gear to push enough exhaust to keep it spooled?

 

[C. Black]

I did the 2G/14b a few years back. It is a nice top-end improvement over the t25, but really not worth your money since you'll more than likely be buying some junked turbo off of Ebay or a boneyard. Honestly, I would skip the 16G also, cause you'll be sick of it in about two weeks (big 16g too). Before I'm flamed **I KNOW THAT THERE ARE QUICK 16G CARS**. And yes, I know that bigger turbos require more $upporting mods, but if you are gonna do it, do it right. Now for LAG......
Spoolup is not an issue, I honestly don't know why people whine about it. If you didn't spool till 6500rpm I could understand, but a 3500-4000 rpm spoolup is NOT laggy in a race environment. How often does your car dip below 3500 in a race??? Do you start your races at a 2500 rpm roll?? If you do, than you don't need a "quicker-spooling" turbo, you need a new driver (or an NA car). DOWNSHIFT, it works.
Remember, you control the rpm, which means you control spool.

 

[Tallen]

umm, you say it sucks. but do you guys have any fuel tuning?....are you poritng it right?

 

[loreak]

installing a 14b can cost less then 200 dollars including turbo, and its an easy swap, you cant even compare that to spending 600-700 for a 16g setup

i installed a 14b on my 2g and i bought the turbo for 125 and bought 30 dollars of parts, i mean it doesnt get much cheaper, how is that a crappy mod, about the same as a shiny intake

 

[C. Black]

Don't get me wrong, if you can't go bigger or money is looking tight for the future, than the 14b can make you happy. Until the $125 turbo blows up, the $10 radiator hose j-pipe blows off above 16psi, the ex-manny gaskets leak like a sive cause you re-used the old ones, not to mention the turbo/O2 gaskets. And your time and labor to pull it all off again, fix it, put it together, blow it up again......
I fully appreciate trying to do the cheap mods, but AT LEAST buy the necessary parts to do it right (like a j-pipe, gaskets, etc). In the end, rigging/hacking will cost you more than you bargained for. Anything worth doing is worth doing right (not that I'm saying the 14b is really worth it, IMO its not). Guys take some pride in your car and quit this ghetto stuff. That doesn't mean you have to have the shiny-intake, biggest turbo, latest core design FMIC, or greatest parts. It means whatever you do, try to do it as professionally as you can.

 

[SPEEDY]

For 2g guys that are swapping to a 14b, you need to remember that your not going to make as much power as a equally modded 1g 14b powered car does, simply because of the larger tb, intake manifold, and better flowing head that the 1g 4g63's have.
