What can I do for you?

*Engine management systems
I have tuned Megasquirt, Microtech, PFC, Haltech, and SAFCs (if you want to call that tuning). In my humble opinion, Haltech is the best bang for the buck. I caution against the E6X because of the different reluctor used in that model. Get the E8 or E11 if you can afford it, or an E6k which is what I use.

*Ignition, Oil, and Fuel upgrade tips
Asking about ignition is going to get you a hundred different answers. I was running a single Jacobs Pro Pak on JUST the leading stock coils. Made 497 wheel. I also did this on a single Walbro pump something a lot of "gurus" here will tell you cant be done (they might also tell you I spray alchohol, dont listen to them.. Lies I tell ya!!!) My ignition is now a Jacobs FC1000. Dont need the 2000 because the Haltech already has a rev limiter. I also run 890 primaries and 1680 Ford Secondaries.

I could go on forever about timing, but I run crazy advances. My engine builder saw the map I was using once and about passed out. Probably shouldnt listen to me on timing...

*Tuning responsabilities
Not sure what you mean here.....

Quote:
*A/R ratio's fitting to my needs
Yet another topic of debate. I run mid to low 11s at full boost with a little lean out in the spool up area, but I also run alot of timing. Some people will disagree, some will agree. At the end of the day, its all up to what you. I also run an MSD Knock Box that lets me know when knock is starting. Pretty handy tool if you ask me!

Let me know what other questions you have.

The problem with the original post is that it's too general, and it would take volumes of text to explain thoroughly.

On top of that, "tuning" is different from person to person.
So there are tuning philosophies that differ from tuner to tuner.
Same goes for turbo sizing...

In general, I normal ask HOW MUCH you're willing to spend and what your power goals are.
Since you mentioned what kinda power you're looking for, you still haven't mentioned how much you're willing to spend?

A GT35R is a nice turbo, but it almost requires a custom turbo exhaust manifold (due to the T3 turbine, unless you go with a custom T4 turbine), and it's on the pricier side when it comes to turbos.
You mention autocrossing and road racing...do they have rules governing modifications?
If you're talking SCCA autocross, modifying the turbos automatically puts you in MOD!

Then we need to take into consideration of your tire set-up...
Most "street" tires cannot take more than 300 - 350hp.
Thus, trying to make more than 400 is really a waste of time.
400hp+ will require slicks to put the power to the ground, or you're going to end up just smoking the tires.
You can argue traction control, but that's a band-aid fix when you can just lower the power levels; less power is always a good choice, cause it lessens stress to the drivetrain and cooling systems.

See where this is going?

Wow, thanks guys. I really appreciate it!

I haven't checked this forum in a while because i completely forgot about my thread.... oops.

Well Id like to make somewhere in the ballpark of 400whp, if not more, reliably. I know my post is pretty vague, but basically what I was looking for is people that may have a similar, or general setup with some intel to what I should do.


Im willing to spend the money to make it happen, and I wont cut corners. Im not in a huge hurry to get the car done, I just want to reach my goal and do it up as nicely as I can.
