yea...i have been using mobil 1, but i was thinking of changing to royal purple just because...idk if its better at all...then i want it lol, (the only reason i would use royal is b/c amsoil isnt really available around here)

 

Ahhhh, update 3/24/09: Due to a problem with my daily, I had to put money into that and ended up not buying Jcats kit. I still hope to get at least what I need to get a low boost install by mid summer and hope to hit my 400whp mark by end of summer. I talked to a guy on clubna-t who has a shop in nj (which I will be in in june) and I might have him piece a kit together for me.

 

Will is300 premade piping fit the gs?

 

kind of...i used a is300 kit...just had to cut a little here and there and use some extra couplers

 

What would the closest be to fit the gs? I would like to make the least amout of cuts and all as I can.

 

seriously...its not a big deal...just get a good hack saw and its really easy...i would just get a good size universal kit from ebay and you will be fine

 

can someone tell me if all i need is:
2 x 90 Degrees Mandrel Bent Pipes
2 x 75 Degrees Mandrel Bent Pipes
2 x 45 Degrees Mandrel Bent Pipes
2 x Straight Mandrel Bent Pipes
2 x 90 Degrees Blue Elbows Couplers
6 x Straight Blue Couplers
16 x Clamps



would that work?

 

Order the universal kit Mark sells with the piping, couplers etc...it has enough to do the whole thing.

 

As far as my tranny, should I get a 6 speed swap to hold the power or upgrade my current tranny? which would be better and more cost effective?

 

I'm assuming you haven't priced out a 6 speed tranny swap since your asking this question as it isn't even in the same ball park price wise.

You will be looking at about $8000 to have the 6 speed swapped in properly.

 

YIKES! never mind hah. I didn't expect it to be that much.

 

Also, I went with the fi/c due to I found a shop that will do the tuning for me and they have been successful with not throwing cels

 

Not throwing CEL's on what type of car?

 

according to the owner, a wide range of cars.

 

Take anything a shop says that doesn't specialize in your make/model with a grain of salt. A "wide range of cars" sounds like someone who is trying to make some money. If they had experience with your particular model he would have said "I did a turbo Gs/Sc/Is" etc... Each car is different, just because they can get it to work on a 2001 Integra doesn't mean it will work on a 2003 Gs get what I'm saying?

The reason I recommended the F10x and SRT is that the F10x is proven to work and work well on YOUR SPECIFIC APPLICATION. SRT isn't that far from you and they only tune Lexus so you know for sure you will have no problems with the tuning/installation. Taking it to someone who doesn't know the "ins and outs" of your exact vehicle and setup is always a 50/50 chance of disaster. Not to mention the fact that if they can't get it to work right you are going to be paying them to use your car as a guinea pig IF they can even figure it out, at that point you could have had a proven setup with a refined tune and been done with it.
