Forced Induction (SC or turbo) installation advise needed

I’m in the process of installing an LMS Super Street Super Charger kit and have some questions regarding “what else” I should do to properly align the kit. I have two local shops willing to do the work.
Even though I’m a GS300 I’m posting this to the IS forums as well since I know a lot of folks have this set up on their cars.
If you all could chime in, I’m looking to see if my approach is correct and the estimates I’m receiving are realistic for the kit (running 6 pounds boost).
Kit install – 8-10 hours
(seems realistic for the mounting kit, IC, piping, SC, etc.)![Thumb Up](https://www.clublexus.com/forums/images/smilies/thumbsup.gif)
Fuel Management
There seem to be perceived deficiencies in the LMS iManage. Do you agree that the best move is to go with a GReddy e-Manage? I think this offers a more reliable and holistic management system since it manages fuel and timing, not just fuel.

Fuel pressure regulator
Is this needed? If so, is there anything better than a Synapse Engineering FPR (Part #SC004)
http://www.boostcontroller.com/index...category%3D232
Upgraded fuel pump (Walbro GSS342 In-tank fuel pump) and custom fuel return system
Do I need this? My understanding was that at 6 pounds, everything could stay fairly stock with no upgrade needed.
Dynometer Tuning
I realize this is an absolute must for the vehicle to run correctly. Does $700 sound reasonable for tuning?
Thanks fellas!! (and ladies)

Kit install time will take a little longer. Just the hardware will take 8 hours then you have to add the time for wiring etc...
E-manage is an Ok start but if you go up any in boost you'll need to toss it out. With the GS300 you can run a 255 fuel pump and 440cc injectors and the stock computer can control with little issues. At that point you will need a cheap A/F converter ( Apexi AFC) to tweak the WOT settings some. This is the easiest setup with the closest to stock drivablity you'll get ( for that boost setting)
As for the fuel pressure reg. - The GS has a returnless system and does no have a return fuel line. Their is no FPR. Also you will not need to do a return system for the GS until you get @ 15 lbs of boost but at that point a head gasket + studs are needed to so; adding a return will just be part of the next step to higher HP.
DYNO - seems about double the price it should be but it also depends on who's tuning. I've always done it myself so it may be cheaper just for that reason.
Good luck and start saving for the next step items. Once you see how easy the GS handles boost you'll never stop!

The SC should be aligned properly once bolted to the adpt plate. The crank pulley should bolt right up and be right in align with the rest with no issues.

They are supposed to have done a baseline dyno yesterday and are going to do a dyno when complete later this week. Should be interesting.

Baseline for the GS300 is 225hp at the crank, somewhere around 180-190 at the wheels. My car dyno'd 188hp/196.62tq.
Now - 285hp/254.08tq with the PMS SS SC. You and I weren't communicating properly. Send me your e-mail.

Ok now I'm really lost LOL. This was a GS300, but yet you post in the IS250/IS350 Performance section, while looking for IS300 comments? ![Uhh...](https://www.clublexus.com/forums/images/smilies/1387914497.gif)
Anyways, don't get me wrong the gains are amazing, but you are so going to get moved LOL
This is an entirely different motor. Thanks for posting though, and have fun with you newly found ball of joy!![Big Grin](https://www.clublexus.com/forums/images/smilies/biggrin.gif)
