Which turbo size is bigger?

[White_Gst]

I've done a little searching before i decided to post this and the results kind of helped but not really. I was wondering if somebody could give me a link or something that will help me find out the turbo sizes from smallest to biggest. i'm going to be doing a turbo upgrade this year and i want to make sure i'm getting the right turbo. i know some things but the difference in sizes isnt something i'm fimiliar with just yet. right now i'm running the stock turbo with the side mount and that's going to get upgraded. however, i don't want to buy an intercooler that doesn't fit the turbo upgrade. i know that bb bo's are better than anything but i'm weary about saying that because of hybrid turbos. anyhow, can someone help me out with this?

Here's a link to the various Mitsubishi turbos and some specs:

Why don't you give us a horsepower goal, and we can help you choose a turbo? Although it is hard to go wrong with a 50-trim.

Also, Ball Bearing turbos have been very over-hyped. You're looking at a few hundred RPM's quicker spool, but huge cost to rebuild, and high initial cost.

thanks ozz. that link was very helpful. black94tsi, i'm don't have a hp goal just yet. i'm still in planning mode. the reason why i asked if i could get the sizes in order from smallest to largest is going along with my i/c upgrade. for instance, i don't want to buy a greddy f/m kit and its not compatible with the turbo upgrade. trust me, greddy is supposedly only compatible with greddy. but i saw a complete turbo upgrade from Turbo Specialties for 3g's and i was thinking of going with it. here's the thing, i bought the car and it had been modified a little and i dont know why the guy gave it up. there's no engine damage to it because the dealer had to bring back up to specs before it left the lot and i wouldn't sign any other paper work until it was done. bottom line, if you check my cars profile that's why i don't know much about the mods that have been put on it. but i know some money was put into it before it was traded in. i mean, its a 97 with 84k on it. moving right along though, i plan on upgrading the turbo this summer and i'm not sure which one the engine will handle. i know the 18g is the most common to get, but i've been searching more and apparently the 20g is better. of course the numbers tell it all, but i don't want to blow the engine before i even get started. therefore, i'm asking all these questions while working on the suspension so i'll know what's keeping the car stable.

Well in all honestly its the 16G that is the most common along with 50trims. If you plan on gettin a 20g is that because you want to stay mitsu turbo or because orf hte upgrade3 line since you can get a BB turbo for as about as much a good 20G unless you go with the TDO5h 20G its around 900 and a good turbo but its all in what you WANT for the car i have never heard tha sayin greddy only for greddy but i have heard it on other parts but not for our cars im not sayin that its not true i jsut have never heard it is all. I run a EVOIII16G right now and i love it its a Great turbo but the SBR GT14 is in my near future BB is the way to go if you have a little bit of money to spend

i don't care if the turbo is mitsu or not...i just relooked at the TS upgrade and the 25bb turbo sounds nice and the complete kit is 3g's. i'm not sure if i want to spend that much. then i relooked at this link http://www.vfaq.net/DSM/mods/10faq.html and it says that the 2nd gens come stock T-25's. now if this is true, why upgrade? is this a better turbo and if buying the non bb TS upgrade, which comes with T25, be pointless? I guess that brings me to ask are the T's better than the G's or visa versa?

okay here is the story line your car comes with a T-25 which is smaller than the 1G 14B turbo that is factory. okay the reason to upgrade MORE POWER the t25 is Quick spoolin but runs out of TOPEND and a decent up grade for you is to get the 14 b from a 1g talon or eclipse ball bearing turbos are the SHIT they spool super fast and are more efficient than most turbos and how much are you willin to spend if your willin to pay 3g's for a turbo upgrade you are FWD drive like me and you said you were investin in SUspension youll need it and for the turbo the hybirds are great turbos here is how the list goes from smallest to largest
13b
t25
14b
small 16g
big 16g
EVOIII 16g
18g
20g
and then on the the hybrids which there are many variations on these too many to list but a great deal would be to get a 50trim granted
DO you have to proper Fuel mods to support a 50trim they are reasonalbly cheap and a killer pump gas turbo

 

[SnowWhite]

No, don't go thinking that the t25 that comes stock with our 2G's is big at all. In fact, it is probably one of the smallest turbo's out there. a 25bb is not the same as a t25. And a T and the beginning or a G at the end doesn't make either turbo better, it just means that it is either made by Garret or Mitsubishi.

 

[White_Gst]

i knew it was too good to be true. so i guess the 18g turbo or going for the 20g would be the better bet? liquordrunk said he likes his evoIII16G and i was going to do a little research on that. i guess you could say that i'm looking to upgrade the stock turbo to one that pulls even at top end and has a quicker spool. i've noticed that my turbo kicks in around 3500rpm but dies shortly there after. i really didn't pay too much attention to that until i read that comment about the stock T25 is actually smaller than what i imagined. however, it does pull hard before it dies which is another thing i noticed. my mechanic said he churped in 3rd which is somewhat amazing to me. i can usually get it to burn tires from start and some of 2nd. i'm waiting until i get better tires before i really give it some gas....thanks for all the help..especially liquordrunk and snow white. that was the info i was looking for...but between the 18 and 20...which is the better to get as far as less lag goes?

 

[liquordrunk]

it all comes down to how much money you want to spend imo a 20 is not worth the money if that is what you want a 50trim is much more reasonaly priced to produce 400whp with proper supportin mods of course but goin with an 18g or 20g is a good choice i would go with the 20g tdo5h it is internally gated jsut as your t25 is if you oppted for the tdo6h you can get it internally gated but it will run you around 1000 and there in lies the questions why by a 20g internally gated if you can buy a 50trim for 800 which will produce more HP and reasonalbe spool around 3500-3800 even the 20g with extewrnal waste gates is like 900 but if you would like those the 20 tdo5h is a great choice quick spool around 3400 on my friends 97tsi talon engine is all stock and he has about 120,000 on the motor..... then again 18g or 20g 20G al lthe way! more power and more fun
so what all mods do you have so far and what are the supsne and tranny mods you plan on doin

Mitsu T25 < Garret T25

right now i just have the venom fuel rail system with upgraded injectors. for suspesion, i have to check the brand springs i have on there because i honestly don't know. i put on a stillen fsb the other day and the car handles almost like a champ. i still have to buy the rear sb and the sway bars. i want to buy another exhaust because the apexi that's on it sits about a 1/4 inch off the ground and there's mad scrappage on unleveled roads. the front scrapping doesnt bother me that much but the exhaust wasn't ran correct and the guy i took it to said that's how its supposed to be ran. so i have to figure out which exhaust to get in order to avoid this problem.

 

[liquordrunk]

WELL YOU ARE DEF GONNA NEED A CLUTCH and how LOW is your car?
your gonna need some sort of fuel control also SAFC II, a data logger, a new BOV since you have (factory) sucks ass, unless you have one already and with the turbo prolly an install kit!

 

[Jeff_Jeske]

My advice is dont get anything smaller than an EVO16G.

I have the FPBIG28 with all supporting mods. I am flowing 34LBS of air which is Big16G territory. I am disappointed.

I have ridden in EVO16G powered cars and they spool just as quick but produce much more power up top.

Also dont go getting small injectors. I got 550cc's thinking they would hold me over for awhile but honetly I was stupid. There is no reason not to get 650+ right off the bat.

Amen! I still have my 550s sitting around and nobody wants them. :thumbdown

 

[White_Gst]

i guess i'll start looking for bigger injectors than 550's i'm pretty much working on suspension now...i already have rims and tires but it's rainy/snow season and i'd rather wait to put them on so i don't run the risk of anything. but i guess i could ask what exhaust is best for 2nd gen clipses? the apexi isn't working for me because of how the pipe is run from the cat back...it scrapes on uneven ground which means no highway driving in this state...
