2g 14b turbo tight budget

[jasjasbinks]

Hi, noob here. i have a 95 2gst a/t stock. i also have a 14b turbo and plan to put it in my 2g. Problem is i have a really tight budget and a 240-250hp goal. below is my super budget setup:

boost gauge
manual boost controller
after BOV (recirc)
stock injectors 450cc
stock fuel system
stock smic

given this setup, will i hit my 240 hp goal? i plan to boost 14-15psi. Is it worth it or should i just sell the turbo back and stick to my t25?

Thanks in advance! let the flaming begin!

If you get your 14b on there and want to go further he's what I would do and in the order I would do it. First I think you should get a datalogging setup. Learn and get used to looking at your injector duty cycle, knock... things like that. That way you can see if you are running out of fuel and know what to look for. Then get an MBC, a boost gauge, and a 1g BOV. Try turning it up a bit at a time and do some datalogging. Once you see about 85-90% injector duty cycle and some knock, then it's time to upgrade your fuel system. I'd go for a used EVO9 pump and some EVO injectors. The EVO9 pumps are better than the 8's. But for your power goals the 8 would work just fine. The EVO8 pump has a relief valve that starts cutting fuel around 23psi. Once your fuel system is set, then I'd get an SAFC or something similar. Do some datalogging to find out when your car is pulling timing or adding it, when there's knock...and adjust fuel accordingly. You could probably get it tuned somewhat ok doing that. But I would for sure get a wideband at the same time as an SAFC if you can. Tha'ts what will really help you dial the car in. Then get your intake and exhaust. If I was on a tight budget that's the order I would get things in. Good luck.

I dont mean to hijack this thread, but how much boost can I run safely with the 14b on stock 2g fuel system?

Even though we all have the same cars there is no set number that works for all of them. There are way too many variables. Even if someone had a 2g with a 14b, a stock fuel system, and the same supporting mods and was running 15 lbs with out any problems, that doesn't mean that it would work for you. You would need a logger and/or a wideband o2 sensor to answer that question. I would only run moderate boost levels until then. That's the only way to do it safely.

will there be a difference from the t25 on stock bcs and the 14b on the stock bcs?

Not cool at all. Your noobing it asking questions that can easily be found by doing a search. Compressor map maybe?

hi dsmtuners, sorry to revive this thread but i just want to thank you even though i haven't contributed anything to this community. at long last i was able to install the 14b. the following is what is installed in the car right now.

motor meter boost gauge
greddy bov (copy)
14b turbo (not ported)
manual boost controller
walbro 255lph fuel pump
stock smic

i must admit that there is a night and day difference between 14b and t25. lag increased a little tiny bit, say from 2500 rpm to 2800 rpm. boost is wild ass crazy! with the t25 installed, boost gauge was hitting .9 bar (12psi?) and then drops to .6 to .7 bar as i go closer to redline. with the 14b, boost hits 1.2-1.4 bar. some belt like screech occurs when i floor it so, i avoid it. and now, my boost doesn't drop.

i know i need to do more readings, but is this a classic case of boost spike/creep? will my 255lph fuel pump be able to handle 1.2 (roughly 17psi i believe) safely without a fuel reg? i tried to turn down the boost but it still hits 1.2 and maybe a little more than that (couldn't keep my eyes on the boost gauge for long)

feel free to flame me. but before that again, thank you. 14b is definitely a worthy upgrade from the t25. it is like i have to get to know the car all over again. it really pulls and it scares the sh*t out of me.

btw, i nailed the boost issue with my faulty boost controller. i put it back to stock boost till i get a decent boost controller. thanks dsmtuners

Get an aftermarket fuel pressure regulator to go with the 255 pump. The 255 will give the stock fuel pressure regulator problems. If you'd gotten a 190 pump or and EVO 9 (or an EVO 8) pump, the stock fuel pressure regulator would have been fine and the 190 & EVO 9 pump can support roughly 350400whp.

Get a datalogging setup and a wideband oxygen sensor too.

thanks flash, saving up for an afpr. the 255 pump sure is noisy
