Need some help

[MaKaPhiLLy]

ok i have a 97 gs 420a with J&E pistons, crowered rods n valve springs, bigger injectors, fuel rail, obx fuel pressure regulator, under drive pulleys, aftermarket cam gears, msd wires, and a obx intake... I have at TD04 turbo and im wanting to boost it and i need some help on a few things...will i need a different ecu or anything and where are some good tuners around Central Pennsylvania..i was thinking GodSpeed near State College but my friend said hes not sure if he'll do it and i want it tuned to its best any ideas?

I dont have experience in non turbo to turbo cars, The only thing I could really think of...A Mass Airflow Sensor and the link to connect it to a tuning program (preferably DsmLink) so it can read the MAS.

Now that you have all this extra air coming into the engine, you will need a way to monitor it and tune it.

Im sure there's more but I only really know about the 4g63T's.
So my apologies for that, but ay...I tried to give you what I know

What's your compression ratio? If you are built with low compression, then I would suggest getting MSnS. For that you'll need tuning. Drop a little more knowledge on what your overall goals are and I can help you with more info.

With all those mods (especially bigger injectors) and a stock ECU, your car must be running like poop...

With that modded of an engine, you should definitely go with Megasquirt. Do a little research on it, it's one of the best options for the 420a platform.

DSMLink is not an option unfortunately.

Here's a nice writeup on how to install it, too- 2GNT.com - MSnS_INSTALL_(parts/wiring_only!)

OOPS I tried though.....
But along with tuning programs, wouldn't he need to upgrade his MAS also?

I also found it pretty weird that he has no current way to tune, or even monitor anything for that matter.

The 420a motor doesn't have, or need, a MAS/MAF.

Ohh, ok....I'll just go back to the 4g63 section where I came from

It doesnt run like poop sometimes it will cut out when you get into it at low rpms but not all the time but ill have to get me the megasquirt then hopefully it will work

thanks for all the help guys
