My_XR6_Turbo Member 282 Member For: 20y 8m 26d Posted 29/05/17 11:58 PM Share Posted 29/05/17 11:58 PM Hey guys, got a couple of questions regarding the turbo wheel size. #1. Can you fit the 84mm or 86mm turbo wheel by machining the original housing or do you need a different housing? #2. I've been reading about the wheel size and the larger you go the more lag it causes. So whats the advantage of the larger wheel and how do you get around this lag? #3. Is it worth putting the large wheel on it or is it better to put something only slightly larger?

You wouldn't fit either to a stock comp housing, you would use a matching or machined 0.7 housing. #2. Apples to apples a bigger wheel flows more air. Primarily wheel design and weight affect spool time when comparing comp wheels. After that engine design and other bolt ons combined with tuning affect it. #3. "Is it worth it" is entirely subjective. If you are only driving in a 60 zone and never anywhere else then you'd want a smaller turbo. If you are solely drag racing and nothing else then you'd want a bigger turbo. Of course there are people who will choose anything in between because of their preference.

Or is it not the done thing? Seeing how cheap some of the billet wheels and covers are makes me curious Link to comment https://www.fordxr6turbo.com/forum/topic/93258-84mm-86mm-wheel/#findComment-1640128 Share on other sites More sharing options...

I've used a gtx wheel in an older style 0.7 housing. You should get your turbo balanced after any rotating mass changes. Just search the forum, there's bound to be more examples. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/93258-84mm-86mm-wheel/#findComment-1640134 Share on other sites More sharing options...

All these highflow floating around atm are exactly that Link to comment https://www.fordxr6turbo.com/forum/topic/93258-84mm-86mm-wheel/#findComment-1640147 Share on other sites More sharing options...
turbotrana Member 2,586 Member For: 22y 29d Gender: Male Posted 30/05/17 03:28 PM Share Posted 30/05/17 03:28 PM I put a Billet GTX wheel on stock front cover and goes great. I also didn't bother balancing mine and its fine. Those billet wheels are very well balanced to start off with. I think your major hurdle is removing and installing without buggering things up. You really should use a proper torque wrench for the job as many stuff up the turbine shaft by over torquing. I would do this if it was a good virgin and unmolested turbo. Then you can take the risk that runout of the turbine shaft is good. Otherwise if molested a bit hit and miss and best left to the pros.

NathanB Member 136 Member For: 11y 11m 4d Gender: Male Location: Melbourne Posted 30/05/17 11:04 PM Share Posted 30/05/17 11:04 PM Would you then recommend if doing it to then get it balanced after it's been re-assembled? And is that just the Chra itself? I did read that thread turbotrana where you did yours and it got me interested. If you look up billet gtx 3582r wheel you'll see that mamba and kinugawa and other Chinese suppliers sell the wheels and also comp covers with backplates. Probably 400-500$$ all said and done.

Expand It might not need balancing after fitting another wheel but you should check it. I paid $100 to get mine checked and fwiw it didn't need balancing. It was a genuine gtx wheel going onto a fairly low km genuine garrett core so that might have had something to do with it. Cheap parts may not have the same results. You won't know if it's safe unless you check. Have a read of this. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/93258-84mm-86mm-wheel/#findComment-1640161 Share on other sites More sharing options...
