16g or 18g. which should i run?

[marquez]

hey i got some questions on what type or turbo to run on my 99 gst. the current mods are a greddy fmic. greddy turbo timer. apexi afc. apexi boost controller. apexi n-1 down pipe and apexi ni exhaust. and injen turbo intake. i was wondering what turbo would best fit my needs. want to get deep into the 13's. so do i go with a big 16g or a greddy 18g kit. if i do go with the 18g kit is that to much turbo and do i have to beef up the internals to run the 18g. thanks

a Big 16 kit is 1100 around or so.... This is just like the base turbo and install kit... now on the other hand the greddy is 2 grand or so... but it comes with manifolds and a waste gate... to my knowledge from other responses a 18 doesnt need an external wastegate... And I was to pay 2 grand I would rather get an AGP turbo which I am planning to get. But to my knowledge the big 16g and the 18g really have little difference if you search questions on it in some of the forums

but at the same rate the AGP kit comes with everything!! EVERYTHING too and is like 1600.... so for the price it varies from 1100 to 1600 to 2000.. thats a huge increment... but your goal 13 seconds... a Big 16 should reach it...

You can also pick up evo III manifolds for 200 and O2 sensor housing for like 200... If you buy a Big 16G

remember these prices dont include injectors and fuel pumps... here is a chart:

www.dsmtimes.org you can see what turbos they used to get those times.


best luck to you... remember ultimately your car is your own... Don't make a mistake of what people tell you... if you really want something then get it... no regrets... especially a turbo... its a very important choice.

Don't buy a Greddy kit, they are way too much money for not enough gains.

 

[marquez]

will a 190lph fuel pump with 550cc injectors be more than adequate for this set up. and with the turbo, what will get me more bang for the buck. im leaning more towards the big 16g. im not sold on the 18g and the whole concept that bigger is better. let me know what you guys think

 

[BOMEX DSM]

You can always get a Mitsubishi 18g for about 700

 

[Nabyar]

The 190lph fuel pump and 550's should be just fine for a big16g.

Also, a big 16g doesn't cost anywhere near 1,100. I don't know where that guy got that number from.

http://www.slowboyracing.com -- Go to Clearance -- They have big 16g's for 550 SHIPPED! Throw on a 200 dollar install kit from http://www.roadraceengineering.com and you're set to go.

On another note, take a look at how many people are in the 12's on a big 16g versus the 18g -- the 18g is junk and not worth the money.

 

[EvolvingGST]

he has a 2g so he needs to buy an install kit for 300 -.-

and the greddy kit comes with fully mountable kits... So im comparing a kit with a kit. I also added in some loose change stuff... Thats why I myself like buying full kits because its easier than piecing together turbos and manifolds and other stuff.....

i dont see why people put down the 18G my friend got one from FP and he managed in a full weight, 91 octane, supporting mods a 12.4 in a GSX w/ the 18G.

 

[1fast97gsx]

people go 12.4 and faster with only SMALL 16gs.

Install kits are $200 max ... nowhere near $300 and the turbo itself is $550 - $650. That's a max of $850 ... don't know where this guy got $1100 from.

 

[DSMTurboEclipse]

Why not run a 20G? I love those turbos!

 

[crankbender]

Why is everybody knocking the 18g. If you don't have first hand knowledge about the turbo don't say bad things.

Do not let yourself get sold on the "bigger is better" idea. In fact the smallest turbo that will get you to your goals is usually the better idea.

IMHO both turbos are good. Go with whatever you would like in the end that is all that matters between these 2 (kinda like asking if you like the blue or the black DSM better ).

for the money the 18g just doesn't give the best results. for the money of a 18g you could get a 50 trim. i tried both the 18g and 16g and i liked the 16g better spools a lot quicker and is a better overall value. good luck man

Very true. 18g's are just ridicously overpriced for how much you get out of them. Thats why I knock them. If you found one for relatively cheap then by all means get it.

I personally like the 18G and will stand by it, I ran a best of 12.10 @ 18psi with this thing, same boost level I was running every day.

since you dont have any fuel upgrades yet get the small 16g and 550's with a 190lph pump you will need a safc or something to control the injectors. Many people are running solid 13's with that.

 

[umiami80]

GET THE AGP for that price, you'll like it. You'll never have traction, so might as well have topend and midrange. Save for a LSD as well, best 1/4 mod you will EVER have.

 

[papifry]

you guys are are all arguing over which is better... 16, 18, or 20g. I have to replace my turbo because it is blowing oil into my intake and the highest I can go is 16g, so here is the question...

Considering I am running stock everything except for an intake upgrade, 3" mas and a translator box, which is the best next step?

16g-big or 16g-evoIII?

Also, will both of them bolt onto a stock 1g exhaust manifold?

I don't see a reason to not go with the Evo III 16G. You probably won't even creep with stock exhaust. But get it ported just to be sure.

Yes, they will both bolt right up.

 

[papifry]

EVO III it shall be.

So I wont need the $200 install kit that you guys referred to?

 

[ShapeGSX]

The turbo will pretty much bolt right up on a 1G.

 

[papifry]

Great!!
Thanks!
