Turboing my 420A... just a few questions.

[VelocitàPaola]

I was thinking Stage III because I'm going to be turboing, but I may be wrong.

Stage III is a good choice, but I wouldn't install them until you are actually boosting.

Well, I was going to order everything at once and have it all put on at the same time. Is that alright?

 

[baxsom]

That is not a problem, there is a guy (blackmagic) on 2gnt that went from a completely stock engine to a Hahn stage 5(forged internals, portfueler, 20g) all at once. You just have to make sure and keep the wastegate set to not allow any boost until the motor is broken in.

If you are going to do the forged internals anyway, consider just going straight to at least what is considered stage 4. This is basically stage 3 with better fuel control.

What exactly are the Stage IV and Stage V components?

"Stages" aren't universal standards, but here's one way of defining them...

I see, so if I contacted Hahn via telephone/e-mail, I could place an order for a Stage III? That's what I'd like, but I'd rather have the Greddy e-01 EBC, could they replace that part or just take it out altogether and then I buy it elsewhere?

chz i got the crane cams stage 2 sticks i had to have the head flow-en and the exhaust upgraded the cams helped but i got the mean v8 idle, hoping adjustable cam gears will help.

I am trying to find the best turbo kit for the 420a and am almost certain I'm going with the super 16g and upgrade to the max without going to a 20g unless I'm not happy with the whp. But the hahns stage 2 kit comes with some sketchy parts like the fuel pump ect.
So dose anyone recommend a different kit that comes with everything like internals and pipeing ect. Was looking at the T4 but still would prefer a 16g just with a walbro pump and the 2 1/4 inch exhaust seems weak. what is better eagle or Je or crower pistons / rods looking for complete kit.

 

[cHz]

I'm probably going to get Wiseco pistons and Eagle rods and get a 3" turboback made at a local shop. I'm probably just going to get the Hahn Stage II and buy missing link, bigger inj., fuel pump, etc.

No, and that's one of the main complaints from people who opt to go the pre-made kit route: they tend to exhange quite a few kit parts for something better. If you want to select most of the parts that go on your car, a custom kit is really the only choice.

What? WTF

JE makes pistons, Crower and Eagle make rods. Eagles are fine rods, but Crowers can generally withstand more power (they're also about $300-$400 more)

Hahn's a great company, and they try to meet your needs and work with you as much as possible; but they generally aren't very receptive to customers trying to modify the contents of their kits. After all... they have to make money too. The worse case scenario is that you have to buy a few upgraded parts, and you're left over with some original Hahn parts (which you could easily sell).

 

[cHz]

I'm not sure exactly what all components I need if I want to build my own.

Turbo
Injectors
Fuel Pump
Exhaust Manifold
FMIC
IC Piping
BOV
Gauges
Boost Controller
Air/Fuel Controller

I know all the main things, I just don't know the little things.

You shouldn't need injectors for basic 8 psi setup.

You will want to invest in some sort of fuel management (ie FMU, SFMU, etc.)

Also downpipe will be needed, various flanges and gaskets... Wastegate setup (internal, external). Basically GSGOINFAST has all the components in his writeup. Take a look at that and compare that to your list.

I plan on running more than 8psi, probably double. I'm going to be buying cams, cam gears, rods, and pistons as well. I just didn't put that in the list because they aren't part of the actual turbo kit.

If 16psi is your ultimate goal, I think that there are much better things to spend your money on than cams and cam gears.

What you're looking for is a "stage III" setup: a rebuilt bottom end; an upgraded exhaust; and your basic turbo kit with a FMIC and some sort of upgraded fuel management (S-FMU would work great).

Right. Well assuming I have enough money for everything, which I most likely will, is there something better to purchase besides cams/cam gears if I already have everything stated?

Axles, Quaife LSD, wideband air/fuel gauge, under drive pulley.

The list goes on.

Are there specific Exhaust Manifolds I need to buy or will ones from a 2g turbo fit?

You need a 420A turbo manifold. They're custom parts that need to be bought from a fabricator or a company that specializes in 420A turbo systems (Hahn, Street Source, etc.). Furthermore, it needs to have the proper flange for whichever turbo you choose to go with, and a wastegate flange if you decide to go for an external wastegate setup.

Everyone has their own opinions on manifolds. Chris has the Star manifold from SBR, and Xavier and I have the Street Source (thestreetsource.net) manifold. All I can say is that I enjoyed doing business with Mike Hart at the Street Source and I think my manifold is great.

I say stay away from turboing ## car because you dont know even the basics

Do yourself a favor. buy all your fittings and tees and gaskets and flanges your going to need and get them out of th way first, because it will suprise you how much they actually cost.

2. http://cgi.ebay.com/ebaymotors/T25-...hZ019QQitemZ8071589399QQrdZ1QQsspagenameZWD1V

thats just 2 flanges and thats over 40 bucks. good gaskets get expensive too.

That's bad advice. Just make sure you read all you can on how to go about doing it and what exactly you need. It is a great experience that you will learn a lot from.

Here's a list of products I made so far...


AEM Wideband UEGO Controller
HKS SSQV BOV
GReddy PROfec e-01 EBC
Hahn 390cc Injectors(bigger?)
Hahn FMIC w/ Piping
JE 8.6 Comp Pistons
Eagle Rods
Autometer Boost/Oil Press/Water Temp Gauges
GReddy Electronic EGT Gauge
A'PEXi S-AFC II(necessary?)
Short Throw Shifter
Garrett T3 Super 60 turbo
Turbo Manifold From streetsource.net
3" Turboback Exhaust
Crane Camshafts(money permitting)
Pilot Cam Gears(money permitting)


Now, I know I'm missing a few things. Where can I buy a Vortech S-FMU? I don't need an upgraded fuel pump or fpr with that, correct? I know I need flanges, gaskets, and oil lines. Can someone recommend me where I can buy like sets of these as well?

You can get an SFMU here: http://www.vortechsuperchargers.com/products/fuel/fuel_fmu.html Also get the adapter kit for 4an line.

Then go here to figure out how to setup the SFMU and find out exactly what parts you need to run the return line if you have the 96+ fuel system:http://www.2gnt.com/nuke/modules.php?name=Sections&op=viewarticle&artid=82


Yes you need a new fuel pump. Get a Walbro 255 for $100 new on ebay.

No you don't need a new FPR you will be disabling the stock one if using an SFMU

oh Yeah, your probably gonna need some 440 injectors if your gonna be running 15-16 psi

THe SAFC is not the easiest to use on our cars, but it seems the majority of people running on a built motor with an SFMU and bigger injectors have it to tune a bit better than the SFMU can tune alone

That is a standard FMU not a Super-FMU

If your gonna have a built engine and run more boost than you want the SFMU because it is adjustable. Still nowhere near as good as MSns or the Portfueler, but definetly usable.
