Kev.O Posted March 12, 2010 Share Posted March 12, 2010 Its cast rather than tubular welded. Much much cheaper to buy but not shiney and pretty lol. Not sure at what level it becomes a restriction but I believe it is at least 600-800hp. Would be fine for your application I think they come in at around £300. I was planning on using one more so for the torque advantages. As Scott correctly pointed out, much cheaper, see the link below: Treadstone Using this type of manifold will probably require some fabrication of the downpipe and wastegate pipework.

Scott Posted March 12, 2010 Share Posted March 12, 2010 Good find Kev, I hadn't tried hard but I did have a browse for a cast manifold for the 2JZ. Didn't find anything. Saved that one to my favourites Quote Link to comment Share on other sites More sharing options...

Saved that one to my favourites It's also the same one that dandan has used for his single install, though he did enlarge the wastegate section from memory.

RobSheffield Posted March 12, 2010 Share Posted March 12, 2010 I personally am waiting for Dandan to map and check his cast manifold before i spec my Supra Quote Link to comment Share on other sites More sharing options...
SupraHuman Posted March 12, 2010 Share Posted March 12, 2010 Check out the OBX Racing manifold Lee, I got one fitted and they are excellent. 321 SS with ltd lifetime warranty. I have a HKS 50mm wastegate, awesome combo. . Priced @ $699 you just can't go wrong. http://www.obxracingsports.com/products.php?pk=1032 Quote Link to comment Share on other sites More sharing options...
JamieP Posted March 12, 2010 Share Posted March 12, 2010 just need one i no will go straight on with my other stuff You will be lucky, xs manifold sits straight where most decent manifolds sit at a slight turn to the engine, meaning ic pipework and downpipe will need modding to install. If it was me id wait till Ryan has checked it over, could be something simple and the current manifold is fine. Quote Link to comment Share on other sites More sharing options...

L33 Posted March 12, 2010 Author Share Posted March 12, 2010 Ok guys thank you How did you find all those? I spen about half an hour last night typing in different things in google with no such luck! Hopefully ryan is having my car the last full week of the month so will go careful until then! He did mention some thing about it not holding boost when on the dyno or some thing like that! Was only briefly mentioned Quote Link to comment Share on other sites More sharing options...

Lude Posted March 12, 2010 Share Posted March 12, 2010 from what i can gather there is no point having a EBC on a Supra, unless you want to run stupid boost, or you still have the decats in. i have mine double decatted, which turns the boost up stupid high. ive got the restrictor ring in the exhaust, so doesnt go above 1.2Bar (does go to about 1.3bar tho) get a restrictor ring. (i have a SAFC for the extra fueling the 1.2bar boost requires, which i admit isnt the best way) Quote Link to comment Share on other sites More sharing options...

Homer Posted March 12, 2010 Share Posted March 12, 2010 Lude, it's a single turbo and therefore *needs* an EBC. Bpu rules do not apply Edit -BTW, the OBX ones do look good. Had a good look at one a local chap had bought and though it wasn't exactly HKS/BL/etc standard it was a different world to XS power. Welding was clean and entry points at the collector were even and well finished. Good VFM if they can be shown to last. Saying that, I'd personally go for the Whifbitz one anyway.

L33 Posted March 12, 2010 Author Share Posted March 12, 2010 As mentioned I'm single turbo Double decat too with no restrictor rings I need to be able to raise the boost to 1.5+ Quote Link to comment Share on other sites More sharing options...

Homer Posted March 12, 2010 Share Posted March 12, 2010 Going back to the original issue, what happens if you turn the BC off completely, do you see variable boost then? It could well be the wastegate exit hole size that a few others have experienced, but best to rule out the basics first. Quote Link to comment Share on other sites More sharing options...
L33 Posted March 12, 2010 Author Share Posted March 12, 2010 I haven't tried turning it off yet, I will tomo as I have a long run to a meet. With the controller off what kind of boost levels should I expect to see? Does the usuall tt boost level still apply even tho I'm single? 0.8 bar I think it is?

JamieP Posted March 12, 2010 Share Posted March 12, 2010 Depends what waste gate spring you have. Quote Link to comment Share on other sites More sharing options...
Scott Posted March 12, 2010 Share Posted March 12, 2010 If you have a 1bar spring in the wastegate actuator then you should see 1bar. If the folks here are correct and the wastegate port is too narrow you will see more though. Quote Link to comment Share on other sites More sharing options...
JamieP Posted March 12, 2010 Share Posted March 12, 2010 The tial 44mm comes with a .6bar iirc, if you want a stronger or weaker spring let me know, i have a couple. Quote Link to comment Share on other sites More sharing options...
Homer Posted March 12, 2010 Share Posted March 12, 2010 As Jamie says, it'll be dependant on the WG spring rate. If your previous lowest run at WOT in 2nd/3rd was 0.8, it would indicate you have a 0.8 bar spring (edit - or lower). However it's best practice not to assume anything when troubleshooting issues! If you turn the BC off and see if you get a consistent result it will help diagnose. Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted March 12, 2010 Share Posted March 12, 2010 I hope its something simple mate, you are having a real challenge with this car and you seem very patient, anyone thinking of going single should read your threads first as a must to give them an insight to the ups and down and costs involved Quote Link to comment Share on other sites More sharing options...

New quality parts and somebody that knows what they are doing installing them for trouble free motoring is the only way to go imo. Quote Link to comment Share on other sites More sharing options...
L33 Posted March 12, 2010 Author Share Posted March 12, 2010 Cheers for the help guys it would be nice to see the light at the end of the tunnel I will try and see what happens tomo I don't really understand the WG stuff tho? Why is there different spring sizes? What's the benefits of different sizes? And not quite got my head around if the manifold is causin a restriction why it would over boost? In my head I'm thinking restriction/blockage would cause under boost as can't release? I no this is wrong but don't understand why I have been patient that's why I've had so many problems/been ripped off and walked all over but hey I have my car back Quote Link to comment Share on other sites More sharing options...
