im looking to stay with the stock rear gear ratio 3.97,the car weighs in 3400lbs with the toyotav8,im going to diet it down to 2900lbs when its lsx converted,the doors are heavy. hoefully i should start working on this by next month . im looking for ideas ,opinions, and interesting information that i would benefit.

 

Doing this same swap for a friend

 

got any pics?

 

Ditch the LS6 cam if you're planning on keeping those short gears and not having overdrive you are gonna need alot more RPM than what the LS6 cam will support..... The LS6 will be done more or less by 6k. I switched from the LS6 cam on my stock LQ4 motor to an Ed Curtis/FlowTech Induction cam and gained a little over 100rwhp at the same boost and a TON of graph making power all the way to 7k. 60lbers will support a little over 700rwhp(750ish) with raised base fuel pressure. Those 3.9X rear gears are gonna suck without OD with boost. For instance with 3.73's my mustang ran out of gear right at the 1000ft mark on 28in tall tires at 136mph making only 655rwhp....

 

i might have set of 3.34 gears, you have good points... il cha t with u soon,thanks.

I am building a Lexus IS300. Here are some quick ways to lose weight:

If your seats are like mine then they weigh a ton
Sunroof was around 35 pounds I think
My doors are cut down to just the skins
The rest was a bunch of small stuff.

I have gutted my car and it still weighs 2920 with half a tank of gas and no driver.

 

i was workin on it today, CLEANIN up the engine bay .
-all the cruise contral.
-ac crap.
i havent gotten into the interior yet,im thinking of slappin in a ford 8.8 rear with adj coil overs anit roll bar set up.

those 3.90 gears might hurt the spooling time

looks like a cool swap

 

Yeah, I have a full roll cage and race seats in the car now. I am still collecting parts for my swap so no engine bay work to speak of.
