Everyone gets excited over a bung. But OEMs use technology to sort it. I love mine. Actually adding a bypass into a baffle when it's closed. Lots of work that though. But valve on its own does help. 1 Quote Link to comment Share on other sites More sharing options...

I did think about this, will have a chat with my exhuast guy and see what can be done, he needs to properly sort out the manifold/exhaust join anyway so whilst he's at it... 1 Quote Link to comment Share on other sites More sharing options...

If the capital has gone that is what loans are for, cards too! Failing that beg, borrow & steal. It is an investment after all. Must be a good feeling to be where you are now with her.

Herb Posted November 11, 2021 Share Posted November 11, 2021 When thinking about a supercharger… have you actually thought about creating a plenum around the throttle bodies? I don‘t know if that would be even possible due to tight space? Quote Link to comment Share on other sites More sharing options...

Must be a good feeling to be where you are now with her. Ha I've already convinced myself that I was spending the appreciation on the car to do the ITBs. Yeah super happy! Even just doing something not many people have done is really satisfying. I'll drive it for a while as is and see if I'm craving more power, then see how I feel. I'd be tempted to go full send on NA and do bottom end stuff as well as port and polish etc, there's definitely more gains there! 18 hours ago, Herb said: When thinking about a supercharger… have you actually thought about creating a plenum around the throttle bodies?

I think the space is just too tight around the bulkhead end unfortunately, it's tight enough just getting a sock on there Quote Link to comment Share on other sites More sharing options...
Noz Posted November 13, 2021 Share Posted November 13, 2021 (edited) I polished my throttle body (there's a lip on the inside) and the Y branch. This is really nasty. It's worth doing the Y branch and hitting the dyno. I sold it to Herb I think. Sure he said he had better mid range just off that. Without even doing the head. The only thing on the bottom end I would do. Is a self build with a stroker crank. Otherwise I cant see there being any benefit performance or for longevity. Assuming no issues calling for work to be done on it. Edited November 13, 2021 by Noz (see edit history) 1 Quote Link to comment Share on other sites More sharing options...

Assuming no issues calling for work to be done on it. When you say Y branch do you mean the inlet? If so I obviously don’t have any of that anymore so there’s no gains to be had there I guess an ultimate goal would be 100hp per litre NA, so to get to that 300hp mark, but that might be a little too difficult, you never know though, maybe someday!

Eightdip Posted November 15, 2021 Author Share Posted November 15, 2021 Also, I’ve managed to put on the socks, and they actually don’t seem to hamper performance/sound which is great news! Lets see if these ones get eaten by the bodies… 3 Quote Link to comment Share on other sites More sharing options...
Eightdip Posted November 18, 2021 Author Share Posted November 18, 2021 Finally managed to get the car to Oulton Park yesterday, and good lord was it worth the wait. Just listen to it Also managed to rip one of the filters already... 1 Quote Link to comment Share on other sites More sharing options...

Eightdip Posted December 25, 2021 Author Share Posted December 25, 2021 Merry Christmas all!! I've finally done a wrap up on how much the ITB build cost TL;DR: it's a lot... 1 Quote Link to comment Share on other sites More sharing options...
Mike2JZ Posted December 25, 2021 Share Posted December 25, 2021 Nice video, nice to know how much it costs. I don't think thats a bad investment given how unique this car is now. Think I'd prefer this over an ebay spec NA-T 1 Quote Link to comment Share on other sites More sharing options...

Think I'd prefer this over an ebay spec NA-T I just wanted a bit of transparancy really, there's already a lack of information out there about ITB conversions, which is the main reason I started this thread and even the channel, but there's even less info on how much it'll actually cost. I thought this would all serve to put people off the idea but if anything most of the comments on the channel are people looking to try it themselves!

Herb Posted December 25, 2021 Share Posted December 25, 2021 Nice info - thanks for the transparency! The sound clip (fly by) at the very beginning of the video is just absolutely glorious. No turbo car can do that for me (no offense here - just personal preference). Quote Link to comment Share on other sites More sharing options...

Eightdip Posted April 24, 2022 Author Share Posted April 24, 2022 Long awaited update! Took the Supra in to SRD to be fettled by the man, the myth, the legend @mike2jz The lads balanced the throttle bodies, and Mike generally worked his magic to eventually get 245whp, which could make it the most powerful NA Supra in the UK? Low bar I know but still a cool clickbait title nonetheless... It was crazy to know how much power the filter socks actually sap, looks like I do indeed need a new solution for filtration! 4 Quote Link to comment Share on other sites More sharing options...

mattdavies Posted April 25, 2022 Share Posted April 25, 2022 Watched this video last night. Its a great build. How does it drive after being at SRD ? Maybe look at the BMW E45 M3 style airbox or similar for ideas Quote Link to comment Share on other sites More sharing options...

Maybe look at the BMW E45 M3 style airbox or similar for ideas Cheers Matt! It seems so much more refined now after the guys did their magic, before it felt a little lumpy in general which I assumed was down to the cams but was likely the bodies out of balance and everything that Mike worked on ecu wise. Genuinely feels like there's more power through the rev range too which is always good Yeah think a custom airbox is going to be the way to go eventually, which seems a shame as it would hide the bodies! 1 Quote Link to comment Share on other sites More sharing options...
Noz Posted April 25, 2022 Share Posted April 25, 2022 Great video. Also great to see the Mike making a lead appearance. I've never seen an NA with more HP. Look forward to see more updates. Would love a video on feedback how it drives now. Quote Link to comment Share on other sites More sharing options...

The only one I've seen with more is Brendan Taft's in the US that makes about 280hp, presumably at the wheels as that has head work, equal length custom manifold and runs on E85 Driving video will be next up, don't want to give everything away at once keep the people coming back for more!
