turbo isf?
So now that these ECUs can be tuned is there any reason why someone couldnt successfully run a turbo setup?
just curious, I know ive seen some turbo setups in the past on these cars before anyone could really tune them but seemed rather pointless, surprised nobody has tried getting RR to get them a custom turbo tune and crank the boost up on one of these cars to see what they can do.

Considering the supercharged cars with the stock 6.5psi of boost are breaking ringlands, cranking up the boost seems like the last thing most people want to do unless they are built. Also I think custom tune would be pretty pricey from RR if they were willing to do it at all.
I dont see why they would charge any more to tune a turbo setup vs a supercharged setup or even a NA tune really.

Because tuning for a particular individuals setup is different than their tunes they build off their own cars and distribute to everyone. Most people prob don't advertise their supercharged issues but there's been multiple engine failures and even a supercharger failure that I know of. Sure its uncommon but for the amount of supercharged cars it's actually concerning enough to me that if I ever were going boost I'd just build preventatively but then you're looking at 20+k for a mod.

That sucks but I guess thats the stuff you can run into when boosting an engine that was not designed for boost.
Definitely hard to justify the cost to build and boost it. I thought maybe we could get away with 8-10 psi on these stock engines and make some good power but I guess not.
its weird that so many people seemed to run 100-150 shots of nitrous without engine issues over the years but just 6.5 pounds of boost is killing them

N2O is seconds. Boost from a supercharger is all the time.

The part number for the pistons in the RC F and GS F is different than the IS F. The ring end gap spec is different for the IS F and RC F compared to the GS F (GS F is considerably tighter). What exactly they changed with the pistons only Toyota knows, but I did think it might be interesting to fit GS F pistons and rings into an IS F engine. Of course if I were going to all that trouble, I'd be a whole lot more likely just to swap in the GS F engine instead.

And yet, all you have to do to get boost is push a little bit on the throttle. With nitrous you have to go WOT and be in the window (on any modern system) so you're looking at seconds with N2O vs. as much as you step on the gas with the S/C. There is a dramatic difference in the amount of stress on the engine between the two models.

I think he just meant you will be getting into boost and seeing higher stress levels way more frequently with a boosted setup rather than nitrous setup.
But ya, technically you can drive a turbo, supercharged or nitrous car and never use boost or nitrous lol

I dont have any issues with those ringlands after my SC kit installed by myself. The cars runs like crazy fast. Especially with e85 blend. Do i track my F? nope. I do spirited driving always. As what rr racing said those who suffered fron ringland failures are F that was bit up before the install.
I was there when josh run his SC F at 11.11 (as what i remember) in the strip. He put a scope to compare his engine vibration to mine and mine is more smoother than his.
My plan is to have the os giken and track this car after i stabilized my resto project.

Motor was not designed to run boost, I don't see the point running turbochargers on an IS-F, unless you take the motor apart and beef up everything.
That will be the tip of the ice burg... you'll have to figure the hotside exhaust manifolds, wastegates and intercooling. You're talking BIG $$$$$$$$$$$$$$$$$$$$$$$.
I'd rather go with a different platform if you want to run boost, something with an iron block and/or that was already turbo from the factory.
Good luck.

Not sure I agree with that. Plenty of cars that didn’t come factory with turbos that are monsters when boosted. Building a motor to run boost isn’t something that’s that crazy now a days. Money is part of the game no matter what platform you’re using. I’m a bit surprised there isn’t any big builds with our platform yet now that there’s a tuning solution. Not saying it pays off but it’s feasible now and there’s always people willing to blow the money.
Yep I agree with this. People will build anything and ive seen some half *** attempts at a turbo ISF over the years on youtube and such before tuning even existed. Just figured now with tuning available someone would do it.
