$1000

[1badturbo]

OK here is the deal i currently have an intake exhaust,boost control,safc,RC 55's,uicp, bov,
front mount and 255lph pump,the car is a 2g gs-t with 177k miles it still runs strong but i came across $1000 and would like to know what turbo i should go with i don't go to the track to often so the goal is not 1/4 mile i do allot of roll racing street highway so i want a turbo that pulls strong up top some lag is OK but not allot and i don't want to boost more than 20psi on the stock bottom end and it doesn't have to bolt up to the stock manifold but i would like it to for ease of installation please help

Any kind of 50 trim or 20g is right up your alley cause anything bigger and you won't be as effiecnt on 20psi and anything smaller isn't really a highway or roll turbo. Of coure there are vartions like a gt12 or gt13(ball bearing turbos) but for the most part you need something 50 trim or 20g size.

I agree with ^ 100%. I would take the extra $ and also add an afpr. If you are running on the highway, it might be beneficial to increase fp just a little to make sure the 550's keep up with the demand.

 

[1badturbo]

what type of 50 trim (model number and manufacturer) like slowboy or scm61 by percision

 

[Slippi84]

No the scm61 is more of a race gas turbo and thus is made to run at like 25+psi to be in it's effeciancey range. I don't want to see you end up like some kid with a wasted turbo cause you went big cause everyone else was doing it. If I were you I would look into the new BB 50 trims from PTE. I just picked up the 60-1 model which is generaly the next step up from 50 trim even though there are other sizes in between. A BB(Ball Bearing) turbo will spool about 300rpms faster average and be slightly more effecient than a non BB turbo. You add those two things to the PUMP GAS KING 50 trim and you have a great DD mixed with a turbo that will pull on just about anything your likely to see on the street on an average day.

turbos to check out :
RS49tBB
scm5031BB
GT12(from SBR pretty much BB 50 trim or there abouts)

 

[1badturbo]

how about the SCM-3231E

 

[Slippi84]

Sure it's a 54 trim which is right up your alley to. Just don't go any higher than a 60 trim if you don't want to run anyth8ing higher than 20psi and even a 60 trim is pushin it. Any reaqson fo only 20 psi??

 

[1badturbo]

S Any reaqson fo only 20 psi??

stock bottom end with 177k miles

 

[Slippi84]

Miles aren't always a indicator of engine state. I won't lie though I wouldn't be pusing a 177k engine much either. I know people that do but I wouldn't take it past like 23psi without some other supporting things to make sure everything was as strong as possible.

 

[1badturbo]

thats what i said but several people have siad "you seem to think that 20psi is all our cars can hold" but they cant seem to understan that not everyone has a built motor

 

[Slippi84]

truu story 90% of dsm guys don't make over 500hp and a stock motor that's been rebuilt to factory spec with arp studs and mls hg will hold 500. sounds like a lot of ppl not trustin Mitsubishi parts.

so a 7 bolt will do 500 hp with refreshed oe parts

 

[Slippi84]

wooooooooo a 7 bolt i don't knwo about 500 my bad i was talkin bout 1g's. I mean i think 7 bolts are slightly weaker than 6 bolts crankwalk aside. I know guys gave put up numbers with them too though. I would do more research on 7 bolts but trust me witha 50 trim and what you want to run your stock 7 bolt will hold in good confition of course.

 

[1badturbo]

so how much power do you think a stock bottom end 2g would be able to hold and no crank walk in 177k miles what are the chances that ill get it now

 

[TOPSECRET]

I think a 7bolt will hold about 400hp mileage may be a good thing if it has'nt crankwalked by now it probably won't. My 1g has 220k and Ihave an evo16g 3" full exhaust and make decent power without worry. Oh and my car gets driven hard daily rode hard and put up wet you can beat a 4g63 they love abuse. Of course I do all regular maintinance use mobil synthetic oils and all factory mitsu parts. If you take good care of them they'll take good care of you.

 

[1badturbo]

now when you say 400hp is that whp or cank hp and thats good to know about the crankwalk since i dont have buch money to sink into th car

 

[Slippi84]

You should be able to get away with 400whp just do a compression test make sure everything from plugs to type of oil is good before you do it though. By the way I don't remember what your goal is but 400 will get you into the 11's so that should be fine for a DD

 

[1badturbo]

i did some dyno searching and didnt find anyone that posted 400whp with a 50 trim they where all 60-1 or bigger so what type of power would i be looking at with a 50 trim and 15-20 psi

 

[Slippi84]

Mor like 320-350whp with a good tune I mean while people say the 50 trim is real good for pump and everything which it is I think they exspect it to put out loads more power than other turbos that aren't great on pump.

 

[Stapl3]

Sure it's a 54 trim which is right up your alley to. Just don't go any higher than a 60 trim if you don't want to run anyth8ing higher than 20psi and even a 60 trim is pushin it. Any reaqson fo only 20 psi??

Trim is just a ratio. It is by no means an indicator of turbo size.

A 14b is a 55trim.

 

[kraka]

Trim is just a ratio. It is by no means an indicator of turbo size.

A 14b is a 55trim.

How is that?

 

[Stapl3]

Trim is the ratio between the diameter of the exducer and inducer fins on the compressor wheel. Trim tells us flow characteristics of a wheel, not size.

Do the math for a 14b, and it's a 55trim. The SCM61 (huge) mentoned above is a 56 trim. A turbo like the SCM32 is a 54 trim, but smaller than the well known "50 trim". Trim #'s mean nothing.

"50 trim" is a slang term in the DSM community.

 

[Slippi84]

If you know that it's slang then why you gonna play semantics with me. HE SAID WHICH TURBO TURBO before I even said 54 trim and how many people you know refer to a 14b by trim. But you are right and I correct myself.

 

[12's]

A local person put down 457 whp on a stock 7 bolt block. For turbos, I have a frank 5 60 trim that would work nicely foe you. It spools about the same as the 20g and 50 trim but it pulls harder. I would want $600 for it. It only has a few thousand miles on it but uses an external wastegate.

You said don't go above a 60trim implying that trim was an indicator of size.
