420A Injectors for a 420A Eclipse...

[2gawdttalon]

Hey guys i got a issue i was wondering if id be able to run stock injectors from a 7bolt motor in my 420A if not what are some good injectors i can use. Anybody know any good sites for cheap motor rebuild kits for the 420a im looking to throw a 16g on it if anyone has any input on that let me know too all the help would be appreciated. Thanks guys for taking the time to read this and replying back with input. Thanks again.

I would recommend www.cimotorsport.net for motor parts. You can built a motor on thier site piece by piece and buy it. As far as the injectors go you can't use 4g63 injectors on a 420A without a resistor pack because turbo injectors are low inpedence and 420A has high inpedence. Even then they still won't work as well because turbo injectors are peak/hold and 420A's use saturated injectors.

I don't know much about injectors, but I'm sure I might be able to help you out on the rest of your question...

As for your turbo kit...I've been able to find a turbo kit for the 420A from Hahn Racecraft for right around $2400 for a Stage 1 (Hahn Racecraft 420A Turbo Kit). Another good place for a 420A turbo kit is from Slowboy Racing (SBR 420A Turbo Kit)

As for motor rebuild kits, you can also find those from SBR for around $500. Hope this helps.

How were you intending to tune your 420a if you used larger injectors?

SAFC won't work in boost on a 2gNT. You will need an SFMU.

You realize the stock 420a can only handle ~8ish psi, yeah? And the stock injectors can handle at least that much. You can boost with stock injectors, and a 12:1 FMU, to about 8psi on your stock bottom end.
