Hey Jeff i pmed you but perhaps your pm is full.I want to ask you adout your new flywheel what brand is it?Did you install it?Also you said your new clutch disc is from aisin NVR 250mm.Is it bigger from the OEM ?Your pressure clutch plate is from spec2 right?Do you think that the fsport pressure plate that i have can use this clutch disc?I hope you see it

 

IS curious,he always explained everything and shows us something new.but this time I think something went wrong and he does not want to talk about it

 

I don't know if something went wrong and I doubt it because Jeff has a lot of knowledge about these staff.I just want to ask about his new flywheel because he doesn't say what brand is it.I m also curious if there s a clutch kit such as Fsport that I have now that can handle more power and torque with the OEM dual mass flywheel.Does the fidanza spec 2 clutch kit can be used with the OEM flywheel?Is it better than the FSport?

 

I think the only solution for our manual transmissions is exedy SMf kit but we have to wait for Jeff to say about this

 

Hey Jeff where are you?

 

Working hard in the Lexus parts dept! LOL!

 

I PMed him once seeking help with a fog light issue but didn't get a reply...

He must get hundreds of PMs lol

 

I've been away in Europe for the past 4 weeks, but just got back. The flywheel was from a machine shop in Asia that does the machining for MFactory and some other concerns. They sell their flywheels online through http://www.light-weight-flywheel.com. It's lighter than the stock dual mass (by about 15 lb) and made from chromoly steel. I had looked into the Exedy SMF setup, and it looks like a good flywheel as well, but it was going to be much more expensive and take an indeterminate amount of time to actually acquire the flywheel by itself without the entire kit.

The clutch disc is an Aisin NVR 21-spline 250mm OD, 160mm ID sprung hub disc. Up from the stock 236mm OD, 150mm ID. The pressure plate is a SPEC, though the F-Sport pressure plate would work well as well. The setup should hold up to about 320 ft-lb of torque, which is about what I wanted to allow for some leeway on the 2GR setup.

Overall the setup feels very good, though I find the engagement point to be a tad on the higher side than I am used to/would like. I will likely be looking into adjusting this in the future.

I've updated a few pieces on the car over the last few months, but I'll probably post about them in a bit.

Hi jeff, it's good to hear from you again, we were all worried here so it's good that you came back.

 

Thank you for the reply Jeff.You should come to Greece since you were in Europe .So you think this Flywheel and this Aisin clutch disc with my Fsport pressure plate would hold the power of 3GRFSE engine and my SC kit?This is the plan Jeff although i missed a great engine from Japan and i m waiting for something new to come up.I saw the flywheel and it s cheap compared to spec flywheel.

 

I would potentially get a heavier pressure plate to be sure (check with SPEC perhaps), I didn't want a heavy pedal so I tried to work it carefully. I would contact SPEC and find out if they have a heavier pressure plate just to be sure.

No time for Greece this time, but next time!

Jeff

 

Thank you Jeff for the reply.I have one more question if you have the time.I ve contacted Paul from PPE about headers for my car.I told him I m supercharged and that the car made 270hp and he told me that I should better go with 350 headers.I told him after about the 3GR engine and he suggested the 350 headers.Mathew from OVtuning told me the same.A friend mechanic keep saying me that if I install bigger headers the car will become slower in all RPMs.I need your opinion Jeff .I hope you see it.Next time if you come to Greece I defenatelly want to meet you!

 

^I think the point they're making is that they believe the diameter of the piping of the 350 headers vs the 250 are larger. To a point you want larger exhaust piping; however, too big, and yes you'll start to power (especially down low).

 

So you believe that I should go with the 250 headers?And if I install the 3GR will they be small for it then?

 

IS250 and IS350 headers are the same from the factory. The only difference is the port size on the head.

Headers should work fine, but as to how much they will benefit you, you probably won't know too much until you experiment with them on a dyno.
