guys/girls I need help on a intake, I want to buy one but don't know which one to go with...any suggestions...

Holla,
JRu

 

why is your post titled 'RIMS'?

 

Well you're asking to open a can of worms...

Here's a few:

RMM
Injen
Weapon*R
Swift Racing
K&N

er, and another one or two I can't remember.

The Swift comes with an ECU which is a good idea, to match the fuel with the increased air flow. Without an ECU, an intake results in some low-rpm response lag.

Some get intakes for the 'flash' under the hood, and for the sound. But if you're getting it for performance, don't expect a whole lot, except for ones with an ECU.

Some have problems with check engine lights coming on that won't go away.

Because of conflicting data, possible lag and engine lights and noise, I'm not that interested in an intake.

 

I just put the SRT HFI w/Race ECU on my GS430, and I'm glad I did, it requires a little more work for installation, but it's the best one for the GS.
Go with the SRT.

 

ok here are your choices, with some pro's and con's:

RMM:

pro: looks good, will work with S-AFC

cons: does nothing for preformance without a chip, and in some cases ( like mine ) slows down the car

SRT:

pro: The real deal, it comes with the intake, a heat shield, and a chip and is one of the top rated intakes for the GS

cons: flimsy heat shield, the ECU cannot be reprogramed for future mods

Weapon R:

pro: looks good, and can be coupled with there own ECU or a S-AFC, and has a very good heat shield

cons: without the ECU the intake doesnt add alot of power, with the ECU the intake is not worth the money, and they dont provide the heat shield with the intake.

K&N:

PRO: well known company for there air filters that comes with a million mile warrenty, will work with S-AFC

CON: looks too plasticy, and has a sorry excuse for a heat shield, does not come with an ECU


Injen:

pro: looks good, and is the strongest stand alone intake, will work with S-AFC

cons: does not come with a heatshield, does not come with a ECU, no aplication for GS400

RS Akimoto:

pro: looks good, and is a very strong stand alone intake, will work with S-FAC

con: does not have a heatshield, there is no aplication for the GS430

This should help you decide, if your going to just get an intake without an ECU then I would go with a Injen for a GS 430 or a Weapon R for a GS400, as for a intake ECU combo, SRT is probably your best bang for the buck, since the Weapon R costs almost twice as much to with there ECU, heatshield, intake combo

 

Can you use the Weapon-R Cold Air Box with the SRT intake and ECU???

 

any problem with the srt/ecu combo with the check engine light, or any thing else???

 

I am changing this thread subject to Intakes, and moving it to the Engine/Transmission fourm.

 

technicaly you could, but it involves alot of work to get it to fit, yur better off making one yourself

not since I got it, I think there were a few people who had problems but that was because SRT sent them the wrong ECU and they switched them for free and no problems since

 

using akimoto funnel ram new IV with WR cold air box, looks and feels much better.

 

All,

I'm a little confused here. Please help.

1. Does an intake without an ECU calibrated for it reduce performance? If so, does it reduce the perfomrance in the low end or throughout?

2. If it reduces performance in the low end, does it increase performance in the mid and high ends?

3. If it increases performance in the mid and high ends, does the increased performance in the mid and high ends compensate for the loss in the low end?

I ask because all the articles I have read on intakes (for other vehicles) state that there is an increase in HP and torque. Here is a link to RMM's website. Check out the claims of increased HP. http://www.rodmillenstore.com/gs_400/intake.htm Also, it doesn't seem logical that these companies would put out an aftermarket performance part that would hinder performance.

Your expertise is greatly appreciated.

Does the Ingen intake only come for the GS 430 and this intake wil not work on the GS 400??

 

MAC,

Whatever RMM claims on their website is not completely accurate.

Remember, 2nd Gen. Lexus GS ECU is different than Honda's. We have OBDII and VVTi. I've heard lots of people complaining about RMM intake. They felt that they were losing power with the intake.

There was an offical Club Lexus Dyno earlier (not sure if Ethan post up the dyno sheet) but he did post up some number. You can use those as your reference. Injen I believe gave out the most gain during the dyno event. If you really want, you could build a CAB yourself for optimal performance.

An intake without ECU recalibration would not produce much gain. The stock fuel map is pretty efficient already.

 

Hey Mike:

You should ask Xavier. He currently has the first generation RMM intake (without heat shield) installed on your old GS400.

Chu...

 

how much did it cost (intake itself plus install)
where did you got it from?

any cons (minuses) with intake so far?
