Help me to choose the turbo please!!!!

[VRMAN]

I agree with CorvetteBoy and that was the point I was trying to make. You can hit that goal with a 16G but that is the hard route to go. Hard in that it takes the most supporting mods, most boost and most tuning knowledge. Why strain everything to the max when using a 60trim or similar turbo will take a lot of stress out of the project. I'm so tired of hearing "well Super X shop made 388whp on a 16G" yes, that's great. And 3,210 average Joe-Dsm's made 275whp on their 16G setups and are all disappointed that they aren't that shop because they just don't have the parts or dyno time to extract every last effecient psi out of the 16G. YOU CAN HIT THAT GOAL BUT IT'S NOT EASY, STOP PRETENDING IT IS. Good luck with whatever you choose.

Im not trying to say its easy, im not saying its hard. It takes comonsence and bolt ons. Like i said i made 303awhp on pump gas at 20psi with the small 16g. ALL bolt ons plus comp cams 100's and an afc. Nothing more, I leaned it out to 11.5:1 on the dyno and thats what the car made. I through in race gas, turned the boost up to 25psi and leaned it out with the afc to 12.4:1 and made 338awhp and then went to the track on these settings and ran a 12.1@112 with my full weight 2g awd. The way my car pulls right now on the evo 16g at 20psi is just how my car felt with the small 16g @ 25psi on race gas. Sure my butt dyno can be off but im going to say its making around 320awhp right now. And in a few weeks ill tune it for pump gas and post the results for you. Granted when i do that ill have a dsmchip chip in my eprom ecu so that adds a bit to the mod list.

Secondly im not trying to start a conflict, but i see too many people go to 50trims right away and not do the job right and make numbers a 16g can. If you get a 50trim and you are happy with 300whp there is somthing wrong. And like i said before, it can be done on an evo 16g you will be at the limit on pump gas doing it ill agree. But its not as difficult as your caps locks make it out to be. Just takes some time, reading and some gerneral knowlege of tuning for a good afr and timing curve.

The good old 20g gets my vote. 20g with a tdo5h exhaust wheel clipped 15*-20*. It'll spool almost as fast as a 16g but rape it on the top end.

Do some research if you don't believe me.

Here's a topic on it from almost 3 years ago 20g with an 18* clip

I think both sides are correct:

1. I don't think it is too terribly difficult to get to 400 hp on an evo3 16G with cams, SMIM, huge intercooler or WI, high rate springs, with a fresh block revving to 8500 rpms or so.
2. I would not do it. Your poor turbo would be spinning at such high rate that she wouldn't last. Why buy a turbo and blow it up? Get a 20G or something that will be turning at under 100,000rpms for most of its life.

It is possible but not practical.

Jeez, if you can't hit at least 300hp with an Evo III 16G, then you sure as hell aren't going to hit 400hp with a 50-trim.

The same supporting mods benefit vehicles with any turbo.

My car isn't all that extreme.
6-bolt 1G engine with 2G pistons
HKS 264/272 cams
Evo III 16G
18" RRE/Griffen FMIC
2.5" custom IC pipes welded up by me (cost all of $60)
1G BOV with gus mod
ND660cc/min injectors
DSMLink
ACT 2600 clutch
3" turbo-back exhaust
K&N FIPK
Hallman MBC
Walbro 255

All of that in a 3350lb (with driver) 2G will get you into the 11s if you run race gas. Frankly, most of that stuff should be installed before you even upgrade your turbo.

I know what someone will say, though. "But you ran race gas!"
If you don't run race gas when you are racing, you are leaving a whole lot of power and SAFETY behind. Again, this applies to any turbo.

On pump gas, I run 20psi daily and it is more than enough power and torque for me. The turbo spools up so quick that if I floor the throttle from a roll in 1st, I'll bark the tires (AWD). On my current snow tires, the car is downright scary when you hit the gas.

 

[CorvetteBoy]

That is very impressive Shape, have you ever ran your car at the track on pump gas boost levels before?

 

[ShapeGSX]

No, my time at the track is limited, and therefore valuable to me. So I try to run my best when I go. That means running race gas. The time is worth more to me than the $25 in race gas that I might buy.

Amen to that
