NW Side. 290 & 6 area. If you arent part of it, join the Facebook group... "Club Lexus - Houston" and roll into Hot Import Nights with us next month. We have a great group of people and cars that help make Lexus a scene in Houston now.

 

Quick update: Gauges came in, but PLX didnt mention i need an 8v converter to run their boost module with their new DM-6 gauge... minor setback while i wait for that small wiring piece to come in now. Wideband just needs the sensor welded in and the rest is wired and ready. Dyno runs still to follow after i get the gauges put in.


Side note: Did a quick run from ~40-100 against my gf's IS350 (F-sport intake, custom true dual HKS exhaust) and have to say we were pretty evenly matched!

 

Good choice..

 

Most nitrous now a days doesn't require a button to activate. It will automatically activate at a certain RPM. I was in the same boat as you. I wanted extra power for drag racing and the additional daily power and thought nitrous was the most feasible option because of cost and WHP yield.

Anyways, I would be interested in some dyno # and time slips.

Found this pretty sick supercharged IS250.

 

When heyarms takes the SC to dyno i'm going with him. 350 F sport exhaust intake and ppe headers! Lets see how the #'s compare =)

 

The word for people who use a button to activate their cars nitrous is pedestrians... (eventually anyway)

 

Good stuff man.

 

So I'm guessing, based off the numbers you said in your first post, that installation was like ~ 1500??

 

Not at all. The numbers I provided was $2300 (for JUST the Procharger blower), and the rest of the odds and ends added up to make a grand total of ~$4k for the complete kit, not including install. Installation was done with a friend, but I also paid him because that's his day job.

Update since I'm posting... PLX 8v converter was lost by USPS last week... so I had to reorder the damn thing, it'll be here tomorrow. Boost/wideband will then FINALLY be installed later this week if my shop can weld it in for me. Dyno to follow. Sorry for the delay to the ones awaiting some numbers. I'm ~1500 miles into being boosted, been pushing it pretty hard, well, as hard as you can with daily highway driving, and trying to keep up with my F buddies last weekend before and after a car meet haha. Feels great, no issues

 

So would putting a 350 engine into a 250 engine be more feasible when considering power, cost, and labor?

I've thought about supercharging but after seeing someone put an isf engine into their 250, i thought about the possibility of swapping a 350 engine..

 

Pretty cool stuff!!

 

You'd need the transmission too... (they're not the same)

And you'd want to have an 09+ 250 so it has VDIM (as the 350 did, and the ECUs would likely expect)

I'd be surprised if it's not cheaper to just trade your 250 for a 350 though, unless you get a good deal on the parts and can do all your own labor easily.

How is this possible? That supercharger giving you 120hp to make up the difference or she was taking it easy on you?

 

Where's your 120hp number come from...?

Headers, full exhuast, 7psi = ~300hp at the crank (my GUESS, and very liberal at that, so dont flame that). Her IS350 with f-sport intake and custom exhaust is 315-330 at the crank i am assuming (again, an assumption). My power band with boost is very likely to be shaped different than a N/A is350. That would be my only answer for you, that her max whp is higher, but my power band may close the gap at the speeds/RPM's we were at.

There's nothing to gain from me lying, if youre assuming that. The is250 is slow, we all know that, and we all know that boosting gives a marginal gain of ~40-70whp. Again, sorry for a delay with the dyno runs.

 

Looking good heyarms, what happen to those ECU tuners in Houston ? havent heard from them . Any up date ?
