Wez Posted January 15, 2015 Share Posted January 15, 2015 For log manifolds the rare Arnout manifold is regarded as one of the best, it has the largest internal area, decent wall thickness and a large wastegate port, think its been used on motors pushing 800hp with newer turbos.

JamieP Posted January 15, 2015 Share Posted January 15, 2015 Hks manifolds seem to crack a lot, there is one in the forsale section now that's cracked and been repaired. I'd go SRD or whiffbitz manifold. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 15, 2015 Share Posted January 15, 2015 The Arnout ones are great, someone mailed me the other week saying they'd found a great condition used one. If I was doing one for myself i would want to try and find one. The Chinese copies are of unknown material spec and the material around the (small) wastegate port is narrow, there may be issues with gaskets blowing out. Again, personally, if I used one of those I would mill a U shaped groove around the wastegate port and drop a copper / asbestos O ring in, like the stock Toyota manifolds use on the manifold to turbo interfaces. I see loads of Trust manifolds that are cracked, too. Quote Link to comment Share on other sites More sharing options...
mellonman Posted January 15, 2015 Share Posted January 15, 2015 Well the next question is going to be the manifold - anybody have a recommendation for a log manifold? I've got to admit, the Japspeed tubular actually looks brilliant at the minute, it's all braced etc. to prevent cracking - it's just the price that worries me. I have bought one of the race spec ones a few months ago when I cracked my xspower one, being that its of similar design so I dont have to change my down pipe and other parts of intercooler piping and induction piping or wastegate , So I wanted the best I could get once I recived it I was suprised how well made it was ,3mm thick to stop the cracking ,mandrel bends, braced but as chris says that will only stop the left to right movment not the up and down or front to back. The welds at the T4 flange where ported so to speak being that all the welds where cleaned up inside to give a smooth delivery to the turbo, I have not fitted it as yet but looks well made to me I can get more pictures if you like Quote Link to comment Share on other sites More sharing options...
98HT Posted January 15, 2015 Share Posted January 15, 2015 I'm a big fan of cast manifolds, especially for your powergoals. Arnouts manifold would be my nr.1 if you can find one. The modified SPA manifold by FSR is also really good and proven for well over 900whp. A little cheaper are the treadstone manifolds. Make sure to get a genuine one! Needs a little bit of porting at the wastegate area, but nothing serious. Very well made. Quote Link to comment Share on other sites More sharing options...
Tsia Posted January 15, 2015 Author Share Posted January 15, 2015 I'm half tempted to get Whifbitz kit minus the turbo, it seems to come with everything I need so it'll save hassle in the long run, and I can fit whatever turbo I choose on to it. Seems to be the ticket right now. Quote Link to comment Share on other sites More sharing options...

Nic Posted January 15, 2015 Share Posted January 15, 2015 Another option if you want a cast manifold is the Powerhouse Racing kit, if you want to source your own turbo then it may be worth asking if they can supply the kit without the turbo. http://www.powerhouseracing.com/p-4795-phr-street-torque-turbo-kit-for-toyota-supra-tt.aspx Quote Link to comment Share on other sites More sharing options...

Tsia Posted January 15, 2015 Author Share Posted January 15, 2015 Odd question - does anybody know the six digit SKU for the S362? Most of what I can find is 'S300' along with an SKU. I've managed to find the one for the S366, but not the S362. Quote Link to comment Share on other sites More sharing options...
James Posted January 15, 2015 Share Posted January 15, 2015 Reading through this makes me want to swap out my T88-34D for something smaller and faster spooling. I'm only running 1.3bar just now, so something like a GTX3582 (always wanted to know what that'd be like on the VVTi ) would probably be a good idea Quote Link to comment Share on other sites More sharing options...

I can't remember the exact figure, I probably never looked, but full boost was certainly before 3500rpm. I would imagine a GTX3582R + Log manifold + SMIC + VVTi would be pretty crazy Quote Link to comment Share on other sites More sharing options...

You would be better off selling your kit and buying another. Quote Link to comment Share on other sites More sharing options...
Supraleeturbo Posted January 16, 2015 Share Posted January 16, 2015 I haven't read through the whole thread but if you like a kit with all the bells and choo choos the Id say go for an Hks kit Quote Link to comment Share on other sites More sharing options...
Ric Posted January 16, 2015 Share Posted January 16, 2015 Isn't your car 200-250km plus? Id be looking at other things before changing to single turbo i think? sorry if thats wrong Quote Link to comment Share on other sites More sharing options...

Sukhy Posted January 19, 2015 Share Posted January 19, 2015 Good information in this thread. I was thinking of going the 67mm turbo route but now with everyones opinions on it, I will go 62. Quote Link to comment Share on other sites More sharing options...
Luxluc Posted January 19, 2015 Share Posted January 19, 2015 Good information in this thread. I was thinking of going the 67mm turbo route but now with everyones opinions on it, I will go 62. Serious mate. With the latest turbo technology, a 67mm turbo is a good choice if you want 800-900 bhp. If I was after 600-700 bhp, I would certainly go for a 62mm unit.

Sukhy Posted January 19, 2015 Share Posted January 19, 2015 Yes as my goal at the moment is for a quick spooling 650 - 700hp, that is what I''l go for. Quote Link to comment Share on other sites More sharing options...
