Anyone run a DOC Race twin scroll exhaust manifold? Looking to see what the fitment is like the only thing I can find is 1 guy running a DOC Race manifold but it wasn't a twin gate manifold.
Having trouble finding quality NA-T exhaust manifold and fitment info ...
I looked at it I was back and fourth on it so much and talking to quite a few people who had one and just wasn't happy with it. What finally turned me off on it was someone had one for sale on supraforums I asked for a close up picture of the collector it was the first picture I could find of the suprastore collector and I wasn't impressed.
I rather just pay more money buy a manifold once and be done with it.
Here is a pic of the collector only one I was able to find
I'm talking with induction performance now, the plan is to have one made through VWR but there will only be an IS300 there in a few weeks for them to mock one on.
I agree we do need a thread for all the manifolds that fit
Yea thats the suprastore manifold collector I got the picture from a guy selling a suprastore manifold because no one anywhere I looked had a picture of the collector.
That looks a lot better then the one I posted. The plan with induction sort of fell through the car VWR was gonna use to test fit isn't available anymore. I don't wana spend close to 2k (CAD) and have something not fit.
Any suggestions I'm running out of time been looking for long time. My harness came in and injectors should be here next week so were gonna start getting the car ready.
If I can't find anything I might just give the suprastore manifold a go.
So I was contact by Juan Figueroa asking if I was still in the market for a manifold he offered a DOC Race twin scroll twin gate like I'm looking for. He assured me it would fit in an IS300
Although after some extensive research I came across this thread about DOC Race. Juan said he has sold many of the DOC Race manifolds and never seen or heard anything like the thread below though. I think I'm gonna pull the trigger on this manifold.
Post #63 specifically but the whole thread is a good read really.
I almost pulled the trigger on a DOC Race manifold a couple years back it was a steal on Supra forums I just didn't have the cash at the time. The quality in the pictures looked awesome. I never looked into the performance results after that though.
So just to update: almost 8 weeks later I still have no new manifold. I kept getting promised it would ship out this day and days later nothing over and over so I got a refund.
It's not Juan's fault but I wish he would have kept me updated. I kept having to chase for answers.
Trying to get my hands on a BP Autosports manifold from a guy off facebook now...
Turns out an internal wastegate EFR B2 frame on the Suprastore manifold won't work in an IS300. So I need to change to an external gate housing and therefore need a new manifold too.
Issues arose with the Suprastore manifold when I went to bolt up the turbo and none of the studs were totally square on the manifold flange. After contacting the company and them telling me to try so many different things rather than admitting it was a bad manifold. I ended up just drilling out their holes but I was trying to avoid that or get anything (even an apology out of them). So I'm trying to not buy one of theirs again if I can help it.
