14b, 16g and a question or two

my97blackgst · #1 05-19-2004, 09:11 PM

Hey Guys,

I was selling my eclipse and the guy backed out on me. So I decided to keep it and do some mods on it. Feel free to correct me if I am wrong. I have found a 14b turbo for $85 and it's in good condition. Also I know I need an install kit for it and it can be had for about $200. So this is an option for me. or I have been thinking about getting a 16g turbo, Is the 16g a direct bolt-on with no kit neccesary? My goal is to go about 330-350hp and that's as far as I would feel comforatble with a fwd. I know the 16g can support that hp range, can the 14b do it as well? I know I need to upgrade the fuel pump, injectors, and some kind of fuel managment and a boost controller for this and get a larger intercooler. How easy is a turbo change to a guy who largest car mod was brakes? And what is the spool range on these turbos? And I have already done intake and exhaust so that's already out of the way. Thanks in advance for the answers.

Cheers
Ben

P.S Also going to do wheels, Is Excel a good brand? I don't need the best, just something that looks better than stock

No, the mitsu turbos like 14b, 16g, 20g all need the install kit or some form of it (custom one, cheaper). 350whp is hard to get to out of a 16g, 300whp or 350 hp at the flywheel might be easier. By the time you are able to get a 14b to perform that well, you would already have a race motor, so no. Only fully prepped 14b's run that quickly.

Which turbo do you need fuel mods for? 14b you might say 190lph pump and 550cc injectors with a S-AFC. 16g might be better with 660's and possibly a 255lph. Not having done a turbo swap before I can't say how difficult it is exactly, but in all reality it can't be that difficult. You unbolt it from the manifold and o2 housing, disconnect the lines and pull it out. Replace with the lines according to which turbo you have (meaning install kit or whatever, feel free to search DSMtuners for '16g install kit' for alternatives). Spool isn't that bad, a 14b might see 3000rpm and the 16g a slight bit higher. You have a new BOV and boost gauge correct?

you have done the support mods first right?

my97blackgst · #4 05-19-2004, 09:50 PM

Cool, Thanks for the reply Joe. And I have done the supporting mods to do this. What I am thinking is for my electronics to go a full apexi setup. Get a apexi trubo timer, safc and a avcr for the tuning aspect of it. I have a 1g bov, boost gauge, air/fuel, and fuel pressure installed already. I was also thinking of just getting the walbro 255lph pump becuase it's only $5 more than the 190lph so why not? As for injectors my thought was 660's. And then I'll get a larger intercooler. I am not dead set on 330-350hp that's just a number I am shooting at. If I only hit 290hp at the wheels I would be very happy. It's alot more than what I am getting right now. Kinda sounds like a 16g is what would suite me best. I plan on doing all the electronics and fuel/turbo mods all at the same time. Not far behind these mods I'll be doing the brakes, the way I figure if I am going fast I need to slow down fast as well.

Cheers
Ben

Make sure you're ready for a turbo upgrade first by doin all the other mods. Boost guage, boost controller, piping, exhaust. stuff like that.

I would suggest the evoIII 16g. quick spooling and high HP possibilities. Just my opinion once you're ready for a turbo.

Import2nr99 · #6 05-19-2004, 09:57 PM

ok, you beat me to it. nevermind then haha

Nstyle29 · #7 05-19-2004, 10:04 PM

i think a lot of people are looking at the evoIII 16g, affordable and high possibilities...what i want to do

BoostedSpyder · #8 05-19-2004, 10:25 PM

Evo 16g!!!!!!

RiceRocket18 · #9 05-19-2004, 11:30 PM

20g!!!!!

BoostedSpyder · #10 05-19-2004, 11:46 PM

Fwd!!!

JoeWagon · #11 05-20-2004, 01:23 AM

You are free to buy whatever, but I would suggest saving money on the AVC-R and going with a manual boost controller. They are as cheap as $50 bucks or cheaper (like mine) and do the same job.

Some people have problems with a 255lph walbro on a stock fuel pressure regulator. I just talked to someone today that said they didn't need it for their new motor. Again, you can read and decide from a search on dsmtuners.

The EVOIII 16g is very close in price to a big 16g, and is a bit better. Quite a few people on this board have the EVO. You could hope for 350whp with that and a FMIC with tuning.

my97blackgst · #12 05-20-2004, 01:44 AM

hmmm....I guess if I don't go over 350whp that 190lph would do good. The less I have to replace the better. I guess the only reason I am thinking the AVC-R is I have always been alot better with a computer than something manual that's infront of me (go figure) The main thing I do with my car is roll on racing from 20mph on up to uh.....fast. And we do stand alone racing (setup a course and see who makes it the fastest with out getting caught :grin

And we have it in classes so all is fair. So far only been beaten 1 time on our road course. Anyway back onto the subject.....I would like to double check that our internals can take 350hp without a problem? And that I should not have a problem with my trans taking this as well (auto)? I don't drag, it's all roll on racing. And what size FMIC that will support 350hp fits "easy" in our cars without moding the front end of it? Thanks for all your answers so far.

Cheers
Ben

Double check the fact that there's a local guy here that ran 11.8 on stock internals with nitrous, and has switched turbos to a 50 trim pushing 44lbs/min on it too. 85k miles. They say 400whp for 2g internals. His experience has taught me that a fast auto benefits from an oil cooler (4 tranny's) as well. I would usually say SBR 2g FMIC kit, but apparently it doesn't fit all too well. There are lots of front mounts, search a little.

I agree with JoeWagon on the internals part....but at that power level can you say....Clutch!

my97blackgst · #15 05-20-2004, 09:43 AM

Hey, Thanks for reply's. Wow....that's all I can say, 400hp on stock internals!!!! amazing..sadly I don't have enough guts to try that. No reason I shouldn't my car has 102k on the clock and runs like a raped ape. So I am sure it could probably take it. You mentioned that an oil cooler would be a good idea, I highly agree with that, But I have a question on that, Don't our cars come with a oil cooler already? or did you mean a trans cooler? Either way it's going to happen, the less transmissions I can go through the better for me. Thanks for all your help so far, you guys are awesome.

Cheers
Ben
