I am looking to get my turbo on, I have done all that is needed to prepare for it on my 420a engine and fuel system I just need to pick to right turbo for my talon and make sure that I am not forgetting anything that needs to accompany the turbo installation. I have done the fuel pump, will be upgrading the fuel lines, not sure what size ID to get but was going to get custom ones from a local shop unless someone knows cheaper. I also have the IC and piping, bov, wastegate, 420a nt to turbo manifold ( cheap $150 ebay version, cast ), I have turbo timer, boost controller, boost guage. I will be upgrading the FPR. I need opinion on what other guages to go with besides the oil pressure guage and the temperature guage. I also need to know what fuel system I can go with that can be handled by the stock ECU, or if not the stock ECU what I can upgrade to ( like the MSNS but something thats AVAILABLE ) and also what I can do as far as the ECU to control all the vehicles peripherals. I have done some research but need direct links to products and opinions from people whom are using such or have. I am most interested in links to garrett turbos but do not want to buy one worth $700, am looking to buy a lower one around $500. I am willing to take links to any good turbos t3/t4 that have been proven to work for any of you. 1996 eagle talon esi is the make, I just cant find any deals on ebay and every site i visit do not specify 420a turbo, so i hesitate to buy from them.

thanks all!
 
Nobody mentions a turbo for the 420a on their sites, because their are no 420a turbo's. Considering the manifold you will be using, any t3 flanged turbo will work for you.

You will also need to have a downpipe made to connect your turbo to the rest of your exhaust.

Don't forget to have a fitting welded to your oilpan for the oil return from the turbo.

MSNS has been available for many years, I don't know what makes you think it's not available. People have been using MS on their 2gnt's for a long time.

The stock ECU can't handle any boost, so you will have to trick it into not seeing boost with a Missing Link or a FCD.

For fuel setups, you have many choices, including the primitive 12:1 FMU, SFMU, or PortFueler. You will need a larger fuel pump, regardless of the fuel setup you choose. Get a 255, since they cost the same as the 190.

Get a boost gauge.

$700 is not a lot for a new turbo - if this is too much, look into eBay knockoff t3 turbo's, or reconsider the entire turbo project.
 
egt gauge i also suggest and a a/f wideband gauge. Like locke said msns is the best way to go if you really want to high boost and willing to learn how to tune alot. But if your just running like 7-9 psi you wont need to tune it besides getting a 12:1 fmu. What are your goals and is your engine stock?
 
If you are woundering about the fuel lines. you can use 6an ss line if you wont to upgrade but its not required. what are your goals for the car as far as boost and hp. Do you hae any engine work or are you still runing stock internals.
 
By fuel pump hopefully you mean a 255 pump.
Fuel lines, you should use -6an.
Your fuel setup, I would suggest a 12:1 fmu or a sfmu. Its up to you, a sfmu is by far better but more expensive. With the sfmu you can control idle/static fuel pressure so you can use bigger injectors.
You will be removing the fpr, not getting a new one. (Replacing it with the fmu or sfmu).
I think you said boost gauge.. but you will definatley need one.
Msns is availble, Im guessing your referring to Pnp Ms. Which no one knows when its going to come out, so I would say for now just go with the fmu/sfmu.
Portfueler is good, but its rather pointless unless you have a way to pull timing. And its expensive, $1000....
For turbo, just search for a t3 turbo.
Like Locke said dont forget your oil lines.
 
I was definitely talking about the PnP-MSNS system, not the one that is around now. I just dont know how comfortable I am with attempting MSNS but I suppose thats about the only good option. I will go with it I think. Appreciate the info on the turbo didnt know most of them will apply and didnt want to buy one blindly. I do have the fuel pump 255 walbro.

What are the benefits to cons of going with the smfu versus the portfueler? from reading it seems that for boost 12psi+ I need smfu or portfueler. I am looking to boost 15-20psi on the strip. factory engine with rebuilt forged internals, crank balanced and polished, all good stuff put in. the top half is tuned and ported and polished. Nothing in the head is new aside from 1 valve and the gasket and the valve head was shaved to make it flat. I have been assured by the ship that did my lower internals that the car can handle safely 400whp with a factory head. is this true? I am most of the way there I am just wanting to order a quality mid grade turbo around $700 thats not going to crap out on me and will last longer than my transmission so to speak. I am upgrading alot of things as described in my first post. also does anyone have diagrams of how they welded on subframe connectors? and I need to know what size steel pipe to use when custom fabricating the internal rollcage. thanks much I will post pics soon!
 
The head, holds up good. Most people up at 400whp upgrade it anway though. And only one person has had complaints on the transsmission, as long as you have a good clutch and a lsd, you should be fine.
A sfmu allows you to control static/idle fuel pressure allowing you to use bigger injectors. This will allow you to run a little more boost, but it is still rather limited. Portfueler however adds 4 injectors that only spray when under boost. So off boost your "stock" so to say... and under boost portfueler kicks in and will allow you to run 20+psi of boost. Portfueler cost about 3 times as much though.
This is all fine and good but running that much boost you should pull timing, just ask 1slow97. He ran around 20psi and didnt pull any timing, he never heard any knock, but it was there and now unfortunatley its toast. (He hit 385whp)
PULL TIMING, not many people do it, and its not talked about much but when your running that much boost your going to need to pull timing.
So my suggestion is to start reading about Msns. For about the same price as a sfmu you can have a parallel ecu control fuel and ingition. You can now control injector pulse rather then messing with fuel pressure and you can pull timing (keeping your motor safe) along with many other things. Just get some large injectors, 1:1 afpr and the appropriate Msns setup.
