I did some searches to see if anyone has any 0-60 times and couldn't find anything. Maybe a video or someone who used a gtech to get an idea. I plan on keeping this great 4.0 1UZ n/a. In this order will be the mods: VBM,3.76 gears, LSD and TC. I will also do the x-pipe where the stock exhaust comes together into a single resonator and some kind of intake with a true cold extension down inside the bumper behind the headlight.

With a good set of sticky tires can these cars break the 5 second mark???

 

there's really not much to do to "highly mod" a GS4 motor short of FI. I recall members with tc/3.76 lsd claiming 5.3 0-60 times.

 

Yes that I am hip on relative to the motor but with all the aforementoined "mods" to everything else...that amount of expense for the common-man is at least substantially modded. Acceleration performance of course is my topic, not handling or braking. Add these two components in to how much you can spend and it will be highly modded. Other things like headers I had not mentioned, porting the head is another.

 

Quickest MAG time was 0-60 in 5.4 from Edmunds.
We did have a couple GS 4 owners claim sub 14 sec 1/4 mile times with the mods u mentioned.

I will be at the track in a week, stock as a baseline and hopefully see times fall as I add mods!

 

BA GS400 runs high 13's with all you actually mentioned before,
Here's what you want to see:

Thanks 1SickLEX!!
Please report what you come up with. I was going to go tomorrow to NEDragway but it is going to be too damned windy. Look forward to hearing what you get for times. Please post here if you can remember.

 

Thanks LEXSOOS-
I actually read this thread you referenced. I don't think I will ever go for the headers. That I bet shaves a tenth or 2. Though I am more interested in 0-60 b/c a 1/4 mile is a long way and it says "give me a ticket all over it" LOL. I am looking to apply this to the road. It ticks me off those darn IS350s can break into the 13s stock with a V6 no less. My goal is to gtech at anything with a 4 in the beginning and anything in the 13s is a 'feels good' for the 1/4 mile.
