Which turbo to get???

[noodles025]

Hey guys I'm just wondering what size turbo would suit my DOHC ZC best???
I only wanna run about 7psi to start coz of the stock internals but eventually when i build up the engine a bit i will run about 10 - 11 psi.

The car is just a day driver and i just wanted something that spools up nice which will handle the extra mods later on.

I can get a stock skyline turbo (rb25det t3/t4) would this be ok or would i need something smaller???

Any help would be great...

Cheers Ash

i would think that a turbo from a 2.5L would be pretty laggy on a D... check out homemadeturbo.com and see what others are using. I have a 14b on my z6 and 8 psi by 4500rpm is fun....

[noodles025]

Yeah the lag was the only thing i was worried about cheers for the help mate

14B or T3 (60 trim)

if you go with the T3 you could always upgrade the compressor side to the T04, and have a T3/T04 later on down the line.

[Jcazz]

T3 42.48......or a T3 Super 60 with .42/48.....i myself iam thinking bout the super 60...check out the guy that just dyenoed his civic with a super 60!! pulled off some awsome numbers!

[iceblue200]

what about a mitsubishi TDO4H 14G turbo its not a bad turbo kinda small but the power delivery is sweet and smooth but its a good place to start anybody with experience on mitsubishi turbos give your opinion please as i am thinking of putting one on my D15B with stock internals and running 8psi

[lsturbohatch10]

14b and 14gs are good turbos for a hmt setup. although, if you already have a turbo manifold, i would just go ahead and get a t3. if your planning on using a cx or hf mani, then i would go with a 14b or a rb05.

T3 42.48......or a T3 Super 60 with .42/48:TU:

[noodles025]

Thanx everyone for your help i think the garrett t3 will be the best option unless someone can show me some figures that suggest the 14g is better. Any advise on where in Australia i can get one that isn't a knock off???

[drunkinmaster1]

garrett turbos all the way. theyre soo much easier to upgrade and find parts for.
the 14b isnt a bad turbo, its just harder to work with. and the upgrades to the 16g turbos arent that significant upgrade over what the garrets offer.
watch out for some of those skyline turbos. some of them have ceramic turbines that have a tendency to snap off at no particular time or boost level.

gt28r small efficient, and ball bearing quicker spool.

[siregcivic]

im using a garret t3 .42 .48 off a saab.. low end in 1st and 2nd is kinda worthless but when it spools 1st gear at 5k it hits like a frieght train and the funniest thing waiting for the boost and when it does.. i dont wheelspin whatsoever.. maybe for just a second in 1st.. its nice

[commandoBear]

rb25's have two small t28's with ceramic wheels and there junk. i allways wanted to run a t28 nissan turbo off a s15 or a gti-r on a d series. fast spool and capable of 15psi and you can rev pretty high with that turbo.

[primercrxSi91]

t3/t4..thats whats i would get..my opinion tho

[98_4drCivic]

gt28r small efficient, and ball bearing quicker spool.

disco potato FTW!

[ryan89crx]

gt28r small efficient, and ball bearing quicker spool.and costs more than my complete kit...

[clockstick]

and costs more than my complete kit...

hey you pay for the good my friend... you just gotta have hook-ups so you can get the Brand new turbo for $650, with garrett warante.
it is just about perfectly sized for a reliable street turbo on stock internals. 220 whp at 9 psi, and you will get that 9 psi by 2800 rpm. Now that sounds pretty good to me. But he didn't say he was on a buget!

[Clutchmaster]

t3/t4 stage III with a 57 trim

[The_Acid_Beaver]

At least a GT28. All the other turbos are cheap, but they are so outdated by the new GT series that it is not funny. Clockstick makes a good point: spooltime. Having more power available earlier in the powerband makes the car more easy to control, especially with the newer electronic boost controllers. (OH, but those are too expensive, too!)

But he didn't say he was on a buget!i dont consider buying a $1000 turbo for 220hp very smart. a $75 t3 would accomplish the same hp goals. i get full 12psi by 3300rpm, fast enough spool for me and im sure im right up there with you in hp range.

thinking that you HAVE to pay out the ass to be boosted is just ludicrous

[commandoBear]

thats why you just buy a t28

[ryan89crx]

thats why you just buy a t28t3 > t28

[AJxr]

ebay 57 trim, or .48 .60 t3

your just paying for the name at that point

[ryan89crx]

your just paying for the name at that pointnot necessarily, the gt28rs is a GREAT turbo. i dont mean to sound like its bad or anything.

but for most people's goals, its not the right one. stock block D motors dont need a $1000 turbo. if you are spending that much on a snail, why are you still rocking the D? if your motor is built, its too small.

stock block - t3 60trim is a great, cheap choice IMO
built motor - t3/t4 50 trim, fast spool, and HUGE sweet spot in the compressor map right around 300hp

sorry I don't want to seem like I am spewing things out of opinion, But volumetric efficiency for streetable goals as well as reliability, along with heat dispertion and loss rates... the GT series turbos are better by alot than the stock t3 turbos. But if I were to build a big hp beast I would not be in the GT series turbos my RX-7 has a td07-25 turbo and makes nearly 500hp out of 1.3L engine.... so I could have gone with a gt35/40r turbo but that would be a waste at that hp goal.

Now I have calculated to the best of my abillity to which turbo size and trim is best suited to a stock d16's exhuast port velocity, VE, Efficiency amoung other things the GT28R is perfect for a streetable turbo that is just as good if properly setup as a stock turbocharged car with all of the reliability of a OE Turbo car. But hey I don't mind spending some money on something that I will get back. But that is another story all together.
But if you are on a budget and don't mind "MAYBE" having a few problems using an old used turbo that's design is about 10 years outdated then Ryan89crx is absolutely correct you can make the same HP at a little more rpm for boost with a larger turbo than the gt28r.... but then again to each their own.

[Dweezil]

watch out for some of those skyline turbos. some of them have ceramic turbines that have a tendency to snap off at no particular time or boost level.

Actually they like to go around 1 BAR, or if they make any contact with the housing. If your in Australiam try to find a S14 SR20 5-speed with as many options as possible, or a S15 spec R, Either one is a ball bearing T28 that's good for about 300HP.

[greasemonky50]

14b set-up i currently have one set at 10 psi on a stock a6 block and i run 13's. its a good set-up and its good for daily driving since i spool around 4000 rpm.

[93delsolvtec]

i would say go for a t-25 or td05h from a dsm. there great turbos and cheap. they spool up quick and have the potential of 15-18psi without spiking
