kevlar_Soul Posted March 12, 2009 Share Posted March 12, 2009 (edited) Hello! My name is Cim, and I'm quite new in the lovely Supra business First of all, check out my car: http://www1.garaget.org/archive/18/17626/117607/117607-1246002.jpg It's a J-spec Toyota Supra MKIV TT - TTC from 1993. So here's my questions: 1. I'm going BPU this spring so I will need to fit a restrictor ring to my HKS exhaust. http://www1.garaget.org/gallery/archive/17626/554512_knib7j.jpg My question is: where should I put the restrictor ring? Between the downpipe and the midpipe? Or am I totally wrong? 2. If I install the restrictor ring is it really necessary to install a BC to? Or will it function properly with only the restrictor ring? My goal is to boost around 1 bar or something like that?! Yeaah, thats it.. Cheeeeers mates!! // Cim Edited March 12, 2009 by kevlar_Soul (see edit history) Quote Link to comment Share on other sites More sharing options...
edge Posted March 12, 2009 Share Posted March 12, 2009 You can buy 1 bar restrictor rings but keep an eye for boost creep when the outside air temps lower. Mine was fitted just after the downpipe.

kevlar_Soul Posted March 12, 2009 Author Share Posted March 12, 2009 So I don't have to install the BC if I have a restrictor ring mounted? Right? Quote Link to comment Share on other sites More sharing options...

kevlar_Soul Posted March 12, 2009 Author Share Posted March 12, 2009 And another question for you guys.. If I decide to install a Dawes Device, where shall I put it? The hose between the Wastegate and ? Quote Link to comment Share on other sites More sharing options...

AndrewOW Posted March 12, 2009 Share Posted March 12, 2009 Lovely looking car, and I think someone's already covered the RR question. Quote Link to comment Share on other sites More sharing options...
kevlar_Soul Posted March 12, 2009 Author Share Posted March 12, 2009 Thanks Andrew! It's lovely as hell. The exterior work is perfect, if you take a closer look at the side- and rearskirt you'll see some amaziiiing custom work! Quote Link to comment Share on other sites More sharing options...
Homer Posted March 12, 2009 Share Posted March 12, 2009 So I don't have to install the BC if I have a restrictor ring mounted? Right? Yes, you don't *need* a BC with a restrictor ring, but it is nice to have that extra control. For example, if you set your restrictor size to keep boost to 1.2bar at 5 degree temps, in the middle of summer you might only see 1 bar. The boost controller allows that little more control to bring the boost levels back up once the weather warms up. And another question for you guys.. If I decide to install a Dawes Device, where shall I put it? The hose between the Wastegate and ? They're not really a good idea, you'd do far better to get a cheap electronic BC so that you have some level of in-car control over boost. If you've not done so already, have a read here (click the blue text): bpu Quote Link to comment Share on other sites More sharing options...
kevlar_Soul Posted March 12, 2009 Author Share Posted March 12, 2009 I've read some different stuff about the Dawes, but it worked well on my 1995 Mitsu Evo 3 so I think that I will try it at my Supra to So where shall I put it? Thanks btw!! Quote Link to comment Share on other sites More sharing options...

I noticed the sideskirts etc, and like it a lot, as it goes with the front really nicely IMO. Quote Link to comment Share on other sites More sharing options...

Thanks btw!! By all means try it, it's only a poor mans way of increasing boost. It will work of course, but they're just a PITA in the long run especially if the temps where you are change regularly. Quote Link to comment Share on other sites More sharing options...
kevlar_Soul Posted March 12, 2009 Author Share Posted March 12, 2009 I'll start with the device, just to try it.. Then later on I will consider another option.. Quote Link to comment Share on other sites More sharing options...
