turbo spec..

what are some good turbo spec for the 2g eclipse 4g63 motor..
i mean like

COMPRESSOR:
-Wheel- ? Trim - ?Inducer / ?Major
-Housing- ? Inlet / ? Outlet - ? A/R
TURBINE:
-Wheel- ? Trim - ?Major / ? Exducer
-Housing- T04 inlet / Insert type outlet - ? A/R

can some one fill in the question marks and or explain what the trim\inducer inlet outlet, wheel trim housing should be??

for example the specs for the HKS T04E

COMPRESSOR:
-Wheel- 57 Trim - 56.3 Inducer / 75.0 Major
-Housing- 100 Inlet / 60 Outlet - 0.60 A/R
TURBINE:
-Wheel- 62 Trim - 74.1 Major / 58.1 Exducer
-Housing- T04 inlet / Insert type outlet - 0.70 A/R

just wondering

thanks

anyone??

How much horsepower are you looking to flow?

just 400-450 hp at 20-24psi and around 325-375 @ 14-18 psi..

thnaks alot

help please :bigthumb:

20G, the only spec you need. Diameters don't really effect flow as much as you would think, blade layout does.

You definetly dont need a 20G for that HP, a Big 16G will be enough, for your requirements

A 16g would do it but not by someone asking the above questions :wink: The average guy is better of doing a 20g or a 50 trim, since with average tuning those number are possible. Then with more knowledge and expereince he'll be able to do that at the wheels :wink: On the 20g I trapped 119 mph, which is about 430 HP for cars that weigh what mine does. 50 trim can do that on pump with good tuning. Thats just my opinion though. 16g is a decent turbo, but 95% of poeple who upgrade to it dont keep it for a year before they want more. I borrowed one for 2 weeks, ran 12.0 at 114 on heavy 2g and gave it back :biggrin: Spools real fast though...

a 16G will never make 450 hp, ever ever.

so 20g it is..

thanks again..

A 20G will make 400 no problem. A Big 16G will, you might have to actually spend some time tuning the car :rolleyes:

tunning the car isnt a problem.. i plan to tune it anyway.. thats the only wat to bring out the full pontental of the car..

I never said it will do 450, but 400-450. ;) But lets look at this. If the general rule of thumb, which has been around since we were all in diapers, is 10 hp per pound per minute of airflow, why is so hard to believe that a 16g will do 450 crank HP? I find the 10 horse per pound/min relates to whp more than crak hp, and I got my 16g up to 40 lbs min. Even at only 15% loss, 400 whp is still 470 crank. I got 47-48 pounds/minute of my 20g, and traps at 119 at only 45 lbs suggesting 440 wheel hp based on the calcs and on other poeples traps vs dyno pulls, like Dre. I dynoed 380 WHP a while back with 38 pounds per minute flow. So I stand by my last post. I'll be dynoing again with the new turbo at 55 pounds per minute, so well see how it relates then. Sorry if this post is an incoherent ramble...

no if i am correct the 16g will spool faster then the 20g right?:confused:

if it does does a 20g take a wile to spool? i heard that it start around 2500-3000rmpz..

thnaks

I have found the 14b spools at 3k rpm, the 16g around 3200, and the 20g around 3500. I used a TDO6H 20g and even that spooled by 3700. A TDO6H 50 trim I ran last year spooled by 3700 as well. Now my TDO6H with GT30/40 hybrid compressor wheel spools by 5k in second and 4500 in 3rd/4th. Anything up to a 20g isnt even worth calling lag. When you shift boost comes right back. And if you floor it and dont get boost, you're a fool for flooring it before 4k rpm anyway, downshift already... :biggrin: My current turbo though will require no lift shifting to ET well. Seems that after the 20g is the jump off. Everything up that point IMO spools plenty fast. In fact, I now believe the 20g is the ultimate street/strip turbo. Big enough to make great power, but spools fast enough for fun on the street. Just my observations though.

The 20g is still a quick spooler...not much slower than the 16g I replaced.

so if the 20g seem so much better then the 16g, it makes more hp and spools the same if not quicker.. then why do people sill buy 16g's?

is it because the 20g takes more modification to fit then the 16g's?

thanks

They are both direct bolt ons, but a 20g requires more supporting mods. I wish I would have skipped the 16g personally, though I did have fun with it.

by supporting mods you mean:

fmic
intake
exhaust
550 or better injectors
upgrade fuel pump
b.o.v.
s-afc or sumthing like that.
upgraded plugs and wires

is there anything else?

The 16g will benefit from all of the same mods above as a 20g will. The main difference is the expensive external WG. You can use an internal on a 20g, but there are very people who can really make it work. Even a 16g with a 34mm flapper WILL blow open. On my SBR 50 trim with 39mm flapper, forget about it. You need a very large actuator to have any chance of making it work. And most people arent comfortable with thier lowest boost being 19 psi. Even though on a 20g or larger you can run 19 psi all day. In fact on my setup I had no trouble running 25 psi daily. OTherwise its the same mod list as one would want for maxing out a 16g.

so if i go with a 20g, i need a external waste gate. wo whar is the lowest psi i can run for the wastegate to work efficantly?

will8-12psi be acceptabel b\c that is what i want to do 4 daily driving..

thanks

You can run crazy low boost on an external, but why would you want to?

to put less stree on the motor for daily driving.. with supporting mods i want to run only 10 psi daily and 18-20psi ..

so im a little confused. what was 95gsxracer talk about with wastegates?:confused:

thanks

Keep your foot out of the throttle and you'll be fine. I have no idea what your second 'paragraph' is referring to.:confused:

Friends dont let friends run 20Gs at 10 psi. I cant let that happen :lol: Get a 16g if those are your goals. 10 psi is absurd. A 20g hasnt even entered its efficiency range yet at that low boost. If a motor can withstand repeated runs at 30 psi, why run it at 10? 15 is more reasonable but still a waste of a 20g. But to answer your question, with a 20g the only way you'll ever get boost that low is with an external. And you would naturally have to request a 10 pound spring.

but running higher then 18psi daily wont ware your motor down alot?

that is what im worring about. if i do run 18psi everyday on a big 20g what will happen to my motor. considering that i run stock internalls.?

but you are right "Friends dont let friends run 20Gs at 10 psi":iceslolan

I run 20-23 psi daily on stock internals. Except when my IC pipe blows off (ghetto rigged SMIC LICP)...then I run 0:tongue:

but what are the long terms affects off running that much boost on your motor, wont it casue added stress on the motor? and cause things to ware faster?

Its not like the gauge is pegged at 20psi the whole time. This is what I think you are overlooking. I don't fully spool the thing every time I take off or anything, just when neccessary, or when I feel like it. You can keep the boost where you want it with a little gas pedal control. I usually keep it under 10psi the majority of the time. This is more than enough to get me into the flow of traffic.

i gotcha ya now!

:bigthumb:

light foot saves motor.. yes i was forgeting that if you have your boost set to a cretian psi doesnt mean that you constantly make that psi...

thanks for explaining that!

I have always run the highest possible boost before knock on all my motors. Never once did it cause any premature wear. Sure it will wear faster than pussyfootin around on it all day, but these motors are strong. Thats why we mod these cars. Stock internals do 500 WHP all day with proper tuning. A little 16g or 20g at 20 isnt going to affect it all that much, unless its a junk motor to start with. :smile:

I was considering a 20G in my planning for future upgrades, but I look at my friend, his best was 12.7 last year, most likely going to hit low 12's this year and planning for 11's next year on his Small 16G. I'm thinking all I want for now is low 12's, so I will probably go with a Big 16G

I actually liked the 16g I ran. I borrowed one from a friend for two weeks, after I shot the turbine wheel of a borrowed 14b out the exhaust (the track officials were thrilled). In that short time I managed a 12.0 at 114.x, on a fat ass 2g. :lol: Spools quick and will make the power if you are set up for it, and are willing to max it out. The 20g did the same times with much less effort. But I also already had the external so that wasnt an issue for me. Eiterh way best of luck :smile:

95 GSXracer maybe when i get my gsx we can meet up and race of sumthin.. your cars sounds nice.

best of luck to you landoawd..

and thanks for all the info..

I need all the luck I can get...I'm a DSMer :)
