I am helping a friend sort out his 420a turbo problems and get his MS2 system up and running.
Little background on myself, I once had an AWD 1990 eclipse 4g63, bigger turbo, MS2 running E85 and all that fun stuff. My knowledge is mostly in the 4g63. The 420a engine is a new engine I haven't been introduced to yet.
I was introduced into this project at a weird time. I don't know if I would have done some of the same mods. It just feels like the parts were pieced together a little wrong but maybe some of the experienced people could give me advice on how to help this project.
Fuel:
It has a 255 walbro in tank, I pulled the hanger and to me it feels like the return line and the fuel out line are way too small. Do people upgrade them and at what flow? or what injector size can these support?
injectors - I was told that it had 700 injectors I am not used to these injectors because they are really skinny. How can I tell what they are rated for? and are they high impedence or low impedence? the last part I guess that I can measure the resistance... I think the 700 are going to get maxed out,
Fuel rail... I am used to having a fuel rail with an in and an out like on the 4g63.... I see only one in unless I am missing something... Is this what the high HP people use for fuel rails? when do I need to upgrade? can it handle 1150s?
FPR- aeromotive FPR was bought because it is a 1:1. I don't know what the stock one was. What is the best way to install this? My eclipse I had a line in and a return line but with one opening on the fuel rail I am kind of confused on how to install this.
Spark
At what HP to the coils give out? I know they aren't rated high. I am thinking I would like to use a 4g63 coil pack and use MS with added ignition drivers to run the coils. Good Idea bad idea?
Turbo
What can I say in that the picture will say it all. I think the turbo is a little big and I would like to use a 16g but this is what it came with. But it will be fun to see what this thing is capable of .
Has a big FMIC to support it and all the hard piping
I think it needs a bigger throttle body, is there an upgrade from the stock TB or is it not worth it
I don't think it will clear the hood...
Bottom end Forged internals so it should take the High Hp and has a lower compression ratio for the turbo.
Engine management MS2 wired up and will be used.
I am just making sure that this car is well sorted out for the person. Is there anything that I may have overlooked or don't know about these engine that I should?
I went over some of the previous posts but it doesn't seem like there are too many people at this level of hp yet on the 420a engines
Thanks for your help!
