Right, and when you overboost your car and blow it all to hell because you encountered piston slap, I guess you're gonna expect Lexus to believe that it was a stock car and the ECU somehow screwed up. Right. Bad gas. Sure.

 

They will find out. It's not hard to see that the bolts have been removed/re-installed before. Also, you will have to cut/modify certain parts of the engine bay and area in front of the radiator to fit the intercooler and IC piping. Not too ethical either to lie about a warranty claim.

I have been thinking about developing a turbo kit for the 2IS as well, but the interest/demand is just not there. By that, I mean the people that will really go though with final purchasing.

 

Very true Jeff, people talk all this sht and when it comes down to it, they won't drop the cash for it.

 

Yeah, what it really boils down to is bang for the buck ratio. The IS350 is no slouch from the factory, so there is not really much incentive for 99.99% of the owners to do anything extreme. The second factor is cost-performance ratio. For example a 2JZ platform such as the 1IS and 2GS, you can buy a $5k kit and put down a pretty respectable 400-450whp. Spending $5k on a turbo setup for a IS350 that will net you around 300-325whp safely just doesn't seem as appealing.

No to burst the bubble to you guys here, but I just don't see this ever coming to fruition. It just doesn't make business sense for a company to invest all this money to develop a kit, and then hear crickets chirping when it comes time to order. I think what really cursed you guys is the fact that these cars are pretty quick stock already. The IS300 had a big tuner following behind it because those things were pig slow off the showroom. Not so the case for the IS350.

If you want a good example, look at the 350Z. They have the Greddy, turbonetics, blitz forced induction setups available. They all cost right around $4-5k and look how many 350z's actually have turbo kits...very few.

Anyways, I'm just rambling at this point but I hope I make some kind of sense.

Conclusion/summary: Both the IS350 and 350Z are pretty quick from the factory so most owners are content with that already and see no point to upgrade to FI.

 

Exactly.....What we need is an IS250 turbo/supercharger kit.... nuff said

 

and how is that different from a turbo kit for the 2is? i mean, wouldn't you still run into the same physical and cost limitations with a supercharger kit as you would with a turbo kit?

forced induction is simply not cost-effective, both for the manufacturer and for the retail end-users. everyone says they're interested in one, but very few of these people actually have the means to afford one, and even fewer actually fork out the money for one. as such, a manufacturer has no financial incentive to produce one for us.

i'm not going to hang my hopes on seeing a turbo/supercharger kit for the 2is in the near future that's actually cost-effective, but you can go right on ahead and hold your breath until you turn blue and pass out for a kit that actually delivers on made promises.

 

That makes even less sense.

If you were willing to drop $8000 to add 50-60 hp with a forced induction kit why weren't you willing to spend $4000 to just get a 350 in the first place for 102 extra hp with full warranty?

 

i was ready to drop the cash on it. Had 8k up on the table for the kit and other ****. Then i got screwed over by you know who. So now im out of that game and out of the 3k for nothing. GL to anyone else in the future though.

 

Also working against us (IS250 and IS350 owners) is of course the IS-F. People who have $8,000 in cash lying around for FI are the kinds of people who would probably just trade up to an F anyway.

 

Hmmm sounds like people are expecting very little gain from the turbo kit. I believe elite is actually planning to change the pistons in the engine and lower the compression ratio( see it in the is-f section)So, i have faith that they will be able to produce
more than the so guessed 300whp-325whp. Stay positive guy!!!

 

Got a link for that?

I looked and didn't see anyplace they mention lowering compression on the 350.

I did find a thread where they're selling their 9:1 CR pistons for the IS-F for $1700 a set. This leaves me pretty doubtful that their $8000 turbo kit includes a piston-swap for the 350.

https://www.clublexus.com/forums/is-...n-pistons.html

(and they never answer the week-old questions in that thread about piston shape either)

 

well loboxracer verified that the isf pistons are of the same bore and stroke of the 350, so just use six of em instead of 8 and you've got your lower compression.

 

Except he also pointed out there's a really specific reason for the stock shape of the OEM pistons and asked if Elite had figured out how to engineer around that while making lower compression pistons... and a week later they still hadn't answered.

All of which still ignores the point that $8000 was never suggested to include a piston swap, and including the labor for such you're now likely jacking your costs well above what it'd cost to just get an IS-F instead.

 

Isnt the whole point of the stratified burn to capitalize on the high compression ratio for a more efficient use of the fuel?

Sooo wouldnt it stand to reason that if we remove the high compression ratio we could also do without the statified burn?

 

there's a reason for the realistic skepticism; allow me to repeat it for you (and you can repeat after me if you like):

COST EFFECTIVENESS

if you or any other 2is owner are willing to drop $8k for the kit, $1700 for new pistons (assuming they're fully compatible), and another, what, $3-4k for all that labor... you're already getting past the cost of trading up to an IS-F just to create that much power, and that's excluding any associated costs of reduced reliability.

unless you have that much money burning a hole in your pocket (i doubt many of us here do - including you and i), it's a pipe dream - and an expensive one at that.

if you're asking us to stay positive, for what reason(s)? hope? promises? a few posts and positive feelings?

as much as we all want to see a turbo kit for the 2is, let's exchange wishful thinking for a moment of reality. seriously...
