Hello club Lexus members,
I have had my 07 is350 for 3 awesome years now and I love this car to death. Only thing that's a bummer is its lack of modification possibilities for the engine. I have heard 1000x to "just upgrade to an IS-F" so please save that comment.

My is350 has the joe-a intake, LMS true duel exhasut, which sounds nice and is a little tiny power gain, but after two years of the same mods I'm looking for a change. I have done a little reasherch on other options for power gains and it seems like besides spending a few grand on a supercharger my only other options are the PPE headers and a 50-75 shot of Nitrous oxide from a company like Zex with there universal kit. They both cost relatively the same amount but I'm not sure how install would be on either product. I was wondering if anyone had opinions on NOS and for that matter who could install a kit to properly in Southern California (Orange County) without me having to worry about my engine blowing up . Or how people have liked a set of high flow headers on there car

Any help would be appreciated folks.
Thanks,
MATICCIS

Bump for some help!

Depends on what you want man.

Headers -> 15whp always on, all the time, no maintenance, safe, foolproof.

Nitrous -> 50whp or more, only available at WOT when activated, have to refill bottles. More dangerous, but if installed correctly and with all the correct failsafes, can be safe as well. If you go this route, make sure to have it installed by someone who knows what they are doing, and don't cheap out on the kit.

I'd go the header + NOS option personally.

maticcis

Gotcha, for headers would you recommednnd any other company besides PPE?
Also what nitros oxide company would you consider buying? And what would a complete "safe" kit contain?

That's the plan sooner or later, I Justine to take my moving slow and enjoy each one

when shopping for nitrous or looking for a shop to instal it you might want to avoid calling it "NOS" if you want to be taken seriously

Also, spelling install correctly would help with being taken seriously as well.

Headers: PPE, OBX (PPE clone)

Nitrous: I've seen a few guys running ZEX blackout kits. You'll want a wet kit for our cars. As far as building a safe kit, thats a rabbit hole and I'm not a nitrous expert. A couple off the top of my head are a WOT trigger and fuel pressure cutoff.

I'd go with PPE Headers and maybe get a midpipe or have a custom one made. There's also the option of getting some carbon fiber parts. Lighter rotors and calipers, wheels.

maticcis

I do not see the spelling error but I appreciate your adivce a lot. It sounds like I should just go with the safe bet and go with the headers and see how I like them.


I'm thinking headers are the right choice as well, and I already have a full cat back exhaust, but what rotors would you suggest going with?

headers all the way. No danger of blowing up your engine. If it has to be one of those 2.

Good suspension mods will help with your feelings too.

I wasn't referring you, I was referring to Sylvan not spelling install correctly. His post was rude and unproductive, IMHO.

As far as Rotors, the only thing that will really help are 2PC rotors. Expensive and rare. Thought about getting some Enkei RPF-1?

Or even better, if you're just looking for more of a fun factor, get the F-sport Rear sway if you haven't yet. Cheap easy mod that you can actually feel. Improves high speed cornering and makes the car more "tossable".

maticcis

Aahh, yea I see. I just tend to not pay attention to the rude people, as there tend to be a lot of them on these types of fourms.
But! As far as the enkai's I already have a set of rims that I enjoy so I haven't thought about a new set of shoes yet .
The sway bar is a great idea for handeling preformance and That may be the route I end up taking, I was just going into this looking for some engine preformance gains.....but I guess this is just the wrong car for that in the end

I always thought dry nitrous setups were safest? I know for a fact that they tend to be easier to install though!
But safety wise, headers. Labour cost is a potential speed bump as I'm assuming you won't be installing them yourself?

srt1

Arent shorty, or any, headers need to be CA compliant???? If so you're outta luck, unless you got that hook up man.

maticcis

Aftermarket headers, intake and exhaust are all "for race use only" but let's be honest that's bull**** haha its for my daily use. The only thing I could see being an issue is that since I have a true duel exhaust already with no cats or resonators that getting the high flow headers will make my car smell like smog everywhere I go


Correct, with something like headers I would rather get someone to do it correctly they try to fudge it myself
