14B ported / polished head install results

[dfresh702]

Just got a 14B and a OEM 2G ported/polished head installed. Boy does it run smooth... Going to have to get used to the 14B not spooling as quickly, but it sure does pull more in the top end.. Pushing around 17-19 psi, and it actually holds at that psi longer. Excited to see what i can squeeze out of this thing.

Next Project:

fuel pressure regulator
650CC injectors

Will post results when complete!

nice...but a 16g would've been a better choice, kinda surprised the 14b holds boost up to 19psi. what injectors are you running? 450ccs?

 

[dfresh702]

Stock injectors i believe.. Walbro fuel pump as well.. I was surprised too... I need a boost controller lower it down to 16 psi..

well get you a 16g soon, youl get tired of the 14b soon and if i were you id get the fp exhaust manifold, gonna make it spool a lot faster...

 

[dfresh702]

Thanks man i will definitely look into that manifold.. Can you usually find them for a good price?

also, i have a custom exhaust mani.. i just need another slim fan for it to fit. im sure that will help with the spooling issue

14bs are definitely a worthwhile upgrade over a t25.
If you're looking to squeeze a little more out of the turbo, look into finding a used 7cm turbine housing for cheap.
Not sure if i'd bother with any custom manifold and slim fan setup for it, a stock 2g manifold should be plenty..
A 14b is capable of getting you in the 12s on a full weight street car with minimal modifications, especially with e85 nowadays.

Fixed. The Fp manifold provides it's gains further in the rpm band.

honestly bro..the fps are nice, but for your set up, the 2g manifold ported out would work well as well, much better if the o2 housing is ported out too, i done all that porting on my gsx and it does make differences on spool up times

?? why would a better flowing manifold make a turbo spool up slower???? i use the fp manifold and i noticed quicker spool times.

I'm pleased that those were your results. However this is acknowledged by Fp and experienced by many members here. It's not even so much that it "hurts spool" it just doesn't do it any favors so that we can reap the benefits later in the rpm band. If you want to debate this or something go ahead and start a thread. I'll be there.

okay...then why is it a better manifold? if it does nothing much out of the ordinary...why would someone pay 250$ when the stock ones are not bad...

OP, sorry this is getting off topic. We look forward to your future results.

An excellent question. In the beginning they were only $175. They also offered equal to or greater than the performance we were already enjoying with evo3's 2g's and ported 1g's and the owners of the latter were also faced with cracking of their 20 year old manifolds, especially when ported.
The price could not be beat for a great step forward - providing tubular benefits into a small, cast design that exhibits OEM longevity.

But why ever upgrade your mani, after all, the stock 2g mani has gone 10's now for years and years? Lots of reasons to do it and lots of reasons to just save the $250.

my 2 cents as well...i had a stock 2g ported and didn't notice that big of a difference, my spool times could be affected because i have ported out almost anything i could possible..including the head,and intake manifold....

^ im with this guy, if you were trying to milk a Evo III 16g or something for every last drop, yea ok upgrade the exhaust manifold. But if your like me (1g guy) I got an EVO III manifold for example, the difference in flow of it and the FP unit isn't significant enough to justify the upgrade..Besides I like heatshields and what not, which is a much easier affair with the OEM Evo manifold.

Just port your 2g manifold, (gasket match it) to a 7cm2 housing, port your O2 housing, get a good exhaust on there if you don't already have one, open up the waste gate passage a little to help with any potential creep issue (don't forget to port that part of the o2 housing) and your good in that area. Get some Evo 560cc injectors an SAFC (can't believe im recommending that thing) a walbro 190lph fuel pump and do the rewire, and your pretty much set for some fun. Course a FMIC and ducted air box would help nicely as well. But in a nut shell there you go an affordable setup thats offers plenty of DD fun.



Now SURE you could take it a lot further than that if you want more power, for instance #### the SAFC go with Link or a 98-99 flashable ECU so you can really tune it right, 255lph pump, AFPR, short IC pipes with a nice FMIC kit, ducted air box or low mounted air filter in the fog light/SMIC area, full 3" turbo back, tubular o2 housing, etc. etc. etc. but theres really no need for any of that on a 14b car. Would you make more power, yea a little but again not really worth the cost for a 14b car. If you later want more power, then do all that in prep for a larger turbo and enjoy.

I'm running the evo injectors with safc and a 2g maf..pretty good combo for 300-320whp plus...on my 16g...plus I'm auto...

A buddy of mine said that the 95's are the only model to come with an eprom ECU.. He has link that i may buy (if my ECU is already eprom).. i have the walbro fuel pump, just need some injectors.. gotta get the boost controller hooked up as well.. I already have that manifold, and i figured a nice slim fan may help my baby cool down quicker.. what do you all think..?

looking forward to the results

You will still need to get your ecu socketed
I wouldn't swap to a slim fan unless you are going to a larger turbo that makes a slim fan necessary... The stock fans are plenty capable of keeping the coolant temps in check...
Before you do any "tuning" of any sort, get a wideband

 

[dfresh702]

Ok thanks.. so before anything else, i need a wideband.. anybody know where i can get one for a good price?

Shit, I'd say the OEM fans out flow most aftermarket units. Slim fans, kind of suck

Slim fans suck? I run two eBay slim fans with no shrouds and my car will rarely get to 200. Car runs at about 185 and that's not light driving either.
