I figured id bring this to the attention of the more knowledgeable people of CSS.NET.

I am looking for constructive critisim not negative ******* comments.

Over the winter, i plan to do the following.


GT30 turbo
Vulcan tubular manifold
Some downpipe from a exhaust shop to match flanges
Bigger intercooler
Clutch
Forged pistions

Now..my question is..is the GT30 the correct turbo i should go with..i will be spending lots of money on making my car fast and frankly i feel the gt30 is the best turbo for this build. any thoughts on anything else? will the charge pipe outlet be in the same placement or will i need to have custom pipes/intakes welded up?

thanks for the input.

 

3.5 inch fmic or bigger. also why are you going 3071 and not 3076?

you will have a little faster spool with the 71, but less HP potential. is your goal just HP? also i wouldnt go with a turbo any bigger on a stock 2.0 than a 3076.

 

well obviously its a little bit of both. but at the end of the day the numbers are what i am looking at.

i havent really looked into the 3076, i will check that out. its the one turbo in the 30 series i didnt take a peak at

also FMIC **** i know nothing about..i have a pretty good handel on FI but not FMIC. care to fill me in..with end tanks and so forth..core size..ect.

 

core size for that size of turbo and HP/ cooling i would do 3.5 or bigger. the end tanks would depend on what can fit under your bumper/ crashbeam. unless you dont mind removing the crashbeam?
the dimensions also depend on if your doing the custom IC piping or keeping stock. if you keep the stockers it would need to be the same dimensions.

 

i see

you mean 3.5 inlet/outlet size right

 

3.5 in/out is perfect, i was talking about core size tho. if you make the in/ outlets bigger than stock you could always upgrade your piping in the future and run the reducer couplings in the meantime.

 

okay that helps.

 

you can also run a QTP cutout for reduced lag.

ported head, intake manifold and turbo hotside would also help reduce lag

 

No that's overkill, 2.5" in/out and piping is fine, 2.75" tops. As for the intercooler, get the biggest one you can fit under the bumper.
As for the intake/piping placement it'll depend on which kit you get, btf has a gt3076r kit that bolts up to the stock downpipe and manifold and even uses part of the stock intake.
You don't need pistons, the stock block will handle that turbo just fine.

 

you dont need pistons...but id rather have ALL peices of my motor forged. no weak links

 

hmm...2,800 bucks seems kind of cheap considering all your getting is the turbo..with different flanges welded on

i mean i could buy a GT30 for 1200 bucks..tub manifold for 700..

 

If you are going to go that extreme, there are plenty of 2.0s running around with a 35R. Coming from the EVO and WRX world, I have MANY MANY friends with this setup and it spools just fine.

 

Get the 3076r forget the 71 and the hahn intercooler and intake mani is your best bet. Thats what im going with and it bolts right up

 

Wouldn't even bother building the motor. Not going to be able to push too much out of it. Buddy of mine has a 08 ss with the dejon swap running Vince's custom tune, hence the ability to bypass the map sensors and run more boost. Don't know numbers yet but keeping door to door with a 440whp srt-4 and beating cars like 04 e55 amg's, 02 z06's would be an example of its moving... The dyno and a thread posting, with everything about the setup will be posted by him, when its all said and done. Just trying to remove the pcv line and hammer out a blow off valve issue. Hopefully that somewhat answers so what of your question. Oh yeah this is still on the stock clutch with 20k mi on the clutch..

 

Your going to want to get the 3bar map sensors though... continuous ass raping of a 2bar map isn't going to help things....

Good charge pipes (the fewer couplers the better in this case)
Intercooler (base it off synapse and hahns) SYnapse uses a Garrett core 24x8x3.5" 600 hp
Downpipe and turbo elbow
Look into the Synapse turbo manifold... looks great! But any good tubular maifold will be good.
Clutch
Motor Build, and head work (contact ZZP on that front)
but you are still going to run into a fueling issue.... which is going to hit you in the face at about 400-420 whp

 

Fueling issue is also a bigger deal that people suspect.

I remember reading about when the 350 crank hp solstices were being played with the fuel rail was replaced too.

Even if we gain the capability to turn up the fuel rail pressure making us hit the wall...we still have to consider how much can the fuel rail take before failing

 

True... it's not the pressure I am waiting for... its the injector timing tables...

But the fuel pressure will be nice too... we have some wiggle room with the pressure but not too much!

It's a huge issue which is going to cause some problems with big builds like this!

 

The small turbo can turn this car into a handful already and make the first two gears useless as is.

Why disrupt the balance the car has with the K04(or+)?

It's like getting a modern supersport bike and stretching it.

All the R&D for turning out the window, not to mention the double time the LSD is gonna be doing

 

Yeah... thats why I am just waiting. I have a new snail in the garage... just waiting for some HPTuners help!

 

im not to worried about the fuel table issues. just needs time to be worked out.


and steve are you asking why go bigger turbo?? why do people turbo geo metros..because they can..thats what they want to do..thats what i want to do..i wont hold back to see the power of the LNF and if im the first person to blow a motor with a bigger turbo then so be it, ill buy a new motor.

 

I have a smaller version of your turbo ready to go on... .just waiting for some fuel tables to open up...

Mine is a daily driver so I am a little more easy on my car!

 

99 neon saftied for 800 bucks solved my daily driver issues

 

People have blown **** up with the stock turbo already on the LNF.

Engine, trans, lifters...you name it it's been done already JP.

Turbo swapped 400whp LNF's exist already.

Personally I don't want a high way car...and let's face it...unless you are doing a GRINDED LSJ brake swap like ZZP did, you're not having a drag car.

Not saying highway cars aren't fun, it's the balance of this car is too good to completely take it away with a late spooling big turbo IMO.

K04+ when the stocker gets tired and goes out in a spew of white smoke one day

Win.

 

nah, run a 3 inch IC pipe kit and your golden. it all really depends what you want. why run a 2.5?

 

It's a great choice for street/strip. Our Gt30R stage kits are at full song just over 3K in 3rd gear. Granted it will never have the 2000rpm grunt the stocker does, but making 350whp is effortless, making 400whp really is just boost dependant.
On the kappa chassis we made it happen with ALL STOCK hardware. intercooler, piping, 2.75" exhaust, all of it. 23psi. done.

Do it up OP, dont let anyone change your mind. You'll have fun.

about the fuel system- why would you wait to put on hotside hardware? If you can exceed the stock turbo's output by a great deal as is, you only stand to gain more when you upgrade in the fuel delivery dept.
It will happen with either
1) a reflash (to some degree)
2)an intake manifold change.

neither has anything to do with the back side of the motor.

So like I said- Rock on OP. it's only going to get more fun from here.
Ask 08blackSS/TC (Joe). Or better yet try and run him.....
