turbo choice last time ill ask promise

[trevor_zr600]

the project is a midmount turbo rx-1 i am at low elevation and am at the last step in the process i have two turbos on hand a gt2854 from a simons front mount apex kit supposably his big hp kit and also i have a 16t mitsubishi which turbo am i better off going with i would like the most available power and i realize that the 16t is journal bearing being slower spoolup but its on a midmount it cant be much worse than my old rearmount was .

what kind of boost numbers are safe from each turbo i know when i worked at the yamaha shop in town we had an older 310 mcx kit on an apex and it had the 16t turbo so is it really possible for that little turbo to push that much air for those big numbers or was it a selling feature


which would you go with

the 2854 has a tiny compressor on it.. not ideal at all, need a 60 or 71 on the thing to push the kind of air your gonna want to make any decent level of power.

the 16t is also a little on the tight side exhaust side for my liking. they run them on the rear mounts as you have a LOT more heat/pressure loss in the long rearmount header system and need a tight exh side to spool.

I dont like either that much at all, personally, i would sell the 16t and get a bigger intake side for your garrett, its not terrible expensive and then you would be setup perfectly.

 

[trevor_zr600]

how does the 2854 work sso well on the cpr front mounts im just asking because i would like to use one of the two that i have but if not possible then i wont

make your t16 in to a t19 for $400 any bigger turbo and you will have to do your engine up.i have a used mcx box with 310 mapping if you need one.it will work with a t16 or t19. run the write clutching and you will not notice a difference between t16 and the garrett. my brother run a garrett i run a t19 there is no difference between the two.

turbos

boost mod ,that is not true .i have a friend here with a an apex with a rear mount mcxpress with a 19t and he has a 121 track that cant even keep up to my rx1 front mount powderlites that has a 144 track an a garrett 2860 turbo.the garrett turbos are better than the mitsi turbo imho.2860 turbo is still bigger than a 19 t .

 

[boost mod]

your are comparing a front mount to a rear mount not a turbo to turbo.
my brother's sled is a rear mount powder lite dave made the kit for him 2 years a go and we are both running 17 psi and we are dead even the one how wins is the first to hit the gas.

 

[boost mod]

if your friend is using a 121 track he is probably spinning to 70/80 km if he is using mcx clutching he can do a lot better they are well know for to much weight in the heal. makes for leg which is mistaken for turbo leg.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>
We are running 174 so both sleds have the same traction. The weight's we use have lighter heal so the rpm comes up quick and get you in to boost quicker.<o></o>
You probably are right that a 2860 can make more boost than a t19 but unless you are going to do your engine up they can not stand much more then 17 psi.

 

[boost mod]

it must be my spell check adding the faces sorry.

 

[trevor_zr600]

Fern wanna sell my your 2560 or 2860

which would you go with

I have a GT2860 boondocker kit on my apex and a GT2854 Alpine kit on my Nytro.
I like the GT2854 way better because of its rapid spool up and instant power.

Boost numbers running 10000 to 12000 feet:
GT 2860: 20 plus lbs
GT2854: I have run it all day @15lbs

Just depends on what you want at the high end.

I wouldnt use anything that touched cpr ever again on my sled. Did you get a header from Impluse? Or you making your own? What are you planning for fuel tank/seat? Like was said, bigger 28 if you wanting to break the 15lbs mark. Under the 15, the GT25 series work fine.

 

[steveo10]

2854 is a lot more vulnerable to giving you more issues. when you plenty of boost to the 2854, it could get ugly, unless your planning on running very little boost.

2860 dont spoil much slower and can take the abuse.... go with what whats

 

[trevor_zr600]

I'm at low elevation and will only ever want. No more than 14 psi

 

[trevor_zr600]

Which one would you choose if 14 psi was my maximum I wouls want to run

 

[M5-]

I would run the 28 preferably with a new 60 compressor side but even with the 54 its a better turbo because the exhaust is much larger hence way less heat buildup. You really want to swap out the 54 housing for the 60 housing and wheel because at 14 lbs the 54 is flat out making more heat than power and the 60 won't be working near as hard which will save repairs in the future. Listen to what people are telling you here its cause we've all been there and the 60 IMO is the smallest I would ever consider for 14 lbs. Its all about CFM not PSI.

turbos

i ran a 2554 ,a 2560 and a 2860 .the 2560 is perfect for what you want to do trevor .it is good to about 15 pounds and spools fast.i now use a 2860 because i drag race my sled a turn the boost to 18 pounds and this turbo likes that,huge difference.boost mod the sled with the 19t couldnt even keep up when we were already doing 90 to 100 mph .i also have a friend here with an rx1 rear mount 16t and it is even worse .i think trevor would do good with a 2560 for spool up at the boost he wants.i notice when i turn the 2860 down to 10 pounds not as good as the 2560.but i like to turn it up to drag race so that is why 2860 is nice .that is my experience with these turbos.thanks

 

[rx1 fern]

turbo 2560

i would sell the 2560 ,but not the 2860 .i have a new 4 tube header coming and i am putting the 2860 on it .thanks.the turbo is like new condition with bigger accuator and wastegate ported and ceramic coated with very low miles .

You could try these guys on Ebay or Alamo in Calgary.

If reliabillity is any concern go with the T16 it will do all you need,

after that fuel dellivery and clutching will be the difference.

If you want more just upgrade it to the T19 $400 for the upgrade is not bad.
