EleCtRoN Posted December 22, 2017 Share Posted December 22, 2017 I came across this manifold https://www.japspeed.co.uk/toyota-supra-2jz-rs-tubular-manifold.html Anyone that use it? Seems to be a bit better than the typical chinese ones. Link to comment Share on other sites More sharing options...
Mike2JZ Posted December 22, 2017 Share Posted December 22, 2017 I'm running one on mine and have used a few on singles before. Can't tell you how effective they are in comparison to an expensive manifold, but so far I haven't seen any crack or have any issues with boost creep etc. For the money I think it's hard to find anything similar.

EleCtRoN Posted December 22, 2017 Author Share Posted December 22, 2017 Nice! What downpipe do you run in your setup? Link to comment Share on other sites More sharing options...
Mike2JZ Posted December 22, 2017 Share Posted December 22, 2017 Nice! What downpipe do you run in your setup? Japspeed downpipe. Again no issues with it thus far. Sometimes requires some modification depending on exhaust setup, but usually they bolt straight into place to work with the second cat/decat.

EleCtRoN Posted December 22, 2017 Author Share Posted December 22, 2017 All right! You got any pics on the manifold and downpipe fitted? Would be interesting to see how it sits with clearance to everything around it. Link to comment Share on other sites More sharing options...

Would be interesting to see how it sits with clearance to everything around it. If you check in my build thread you should see some photos of it installed on mine. But mine is for a 1JZ head so the positioning is slightly different to the 2JZ manifold, but you should get some idea of clearance from it.

mellonman Posted December 22, 2017 Share Posted December 22, 2017 I have one on mine way better then the xs power one I had before , a lot more robust I did do a little porting on mine to make it spot on but other then that cant fault it for the price ,it wont be as good as the billet inlet flange type but good enough.

EleCtRoN Posted December 22, 2017 Author Share Posted December 22, 2017 Do you use the same 3" downpipe from japspeed as Mike2JZ? Link to comment Share on other sites More sharing options...
Mike2JZ Posted December 22, 2017 Share Posted December 22, 2017 Here is a decent photo of them both install together. The only difference on 2JZ is that the turbo mounting is a little further forward and is twisted a little to the left. Link to comment Share on other sites More sharing options...

Supra-love Posted December 22, 2017 Share Posted December 22, 2017 Very interested in this for my single build next year! Looking old like a good bit of kit and people seem to have good feedback for it! How long has everyone been running them without issues? Is anyone using the 3” cat back they sell also? Can’t find any tube vids of it on a supra! Link to comment Share on other sites More sharing options...

Between 1-2 years now of use across different builds, no negatives to report as of yet. Never tried their 3'' catback system. Link to comment Share on other sites More sharing options...
evinX Posted December 22, 2017 Share Posted December 22, 2017 Good to hear their manifolds are fine. But dont for one miniute think their control arms are of the same quality. Just a friendly reminder on the topic of japspeed. Link to comment Share on other sites More sharing options...

Ill definitely go with one of these then along with the PTE 6466 or similar. Link to comment Share on other sites More sharing options...
mellonman Posted December 23, 2017 Share Posted December 23, 2017 same been running mine for about 2 years , I made my own 3.5 down pipe to fit I gained about 600rpm spool from my previous setup Link to comment Share on other sites More sharing options...
Supra-love Posted December 23, 2017 Share Posted December 23, 2017 (edited) same been running mine for about 2 years , I made my own 3.5 down pipe to fit I gained about 600rpm spool from my previous setup Nice mate, Was thinking of running 4” downpipes (which you can make me if you like) and 4” single box cat back with my setup to aid flow and spool. Edit- just purchased garage whifbitz 4” single box cat back and the 4-3” adapter. So I can now do away with the tanabe medallion. Question - will the car need a new map with this upgrade? Forget about the japspeed 3” one now! Edited December 23, 2017 by Supra-love (see edit history) Link to comment Share on other sites More sharing options...
