Ebay FD T4 Manifold Review

Wouldn't a fuel cut cause a quick lean condition and that be bad, wouldn't an ignition cut be better, isn't that why its better to have an ignition box with a ignition cut rev limiter instead of a ecu fuel cut rev limiter. A very rich map in boost levels above desired boost pressure and an electronic boost controller with a warning and boost limiter features is good, the warning feature beeps at you.

No, fuel cut means no fuel starting fom the next compession stoke which means no more combustion.
On side note, the stock fuel cut on the 2nd gens was bad because it only cut fuel on one rotor.
Ignition cut is good for a rev limiter but not a boost cut.
Boost limiter on a boost controller won't help u if a line pops off or the wastegate malfunctions. If your relying on that for protection, u really have no real protection.

I wasn't able to fully test fuel cut function of the fuel injector circuits on the PFC due to having issues to get it to reliably enter fuel cut...it was sometimes rather inconsistent.
I should be able to get reliable data on this next Spring when my car is back on the road.

it cuts fuel to one rotor on extremely light cruising and some decel situations, on hard decel fuel is cut from both rotors. during Rev cut the Apexi should be cutting fuel to both rotors, i don't even recall if there is a boost cut with the stock FD ECU as the engine usually is toast before anyone can figure that one out.

I will never brag about having ebay parts on my car but the reality is I do. My intercooler/manifold and wastegate are all Ebay Chinese crap. I have made a lot of power on the setup and have never had any issues.
Intercooler (Greddy Copy)= Fit perfectly no leaks or problems, they did send me worm clamps which I complained about and they sent me cheap t-bolt clamps that had weak threads. Easy enough fix.
Wastegate (50mm copy) = I have had two of these on two different setups. Both of them stuck open the first time the gate opened then I would hit it with air compressor to shut it and it would never happen again. My guess is poor quality coating that needed to rub off shaft. No boost problems. If this ever fails I have the proper tuning adjustments that it would not destroy the motor.
Manifold= Tig welded spacer on to make it clear the FC manifold. Has worked well with no cracks or problems. I did not buy from EMusa, they had lots of negative reviews and the stock photos you could spot many imperfections. I bought mine from a different vendor and paid about 60-70 more than the cheaper options. 2nd manifold I had I can not confirm if it was off ebay or not, but it was the same design, I adapted to t6 frame and had a 60 pound turbo sitting on it with the manifold glowing red hot multiple times, no problems. Neither of these have failed.
All in all, I will never suggest to anyone to run Chinese parts over authentic parts. You have to make sure you have all your bases covered so it doesn't destroy the motor. Not to mention using Chinese parts hurts development and profitability of the companies that bring these great ideas and concepts to us. I am a hypocrite and I went this way because cars are a hobby and not worth the extra debt or financial burden to do what is right.

I am using the same manifold on my car, and people who say that this can't/won't make power obviously have no idea what they are talking about and need to STFU. I don't know why everyone feels the need to review a product that they have never seen or used before, and comment on quality. You just make yourself look like an idiot like Iwan instead of giving useful info such as karack and frostycrowd gave us
One of my friends is making 650+ rwhp on his bridged 13b with an HKS t51r. He's been running several months with no issues with the manifold. Both of us had to port/polish the inside of the manifold but that's really minor. If you all are so worried about it cracking then spend a couple bucks to have a brace TIG welded on. Better than spending $800 on $50 worth of tubing, and a couple flanges that are cheap as well.

i'd prefer the HKS cast manifold over any of the others "stainless" manifolds though, they do work but they generally do crack after a few years regardless of how well they appear to be designed and built. you simply can't go wrong with cast iron for the most part, even chinese made it will outlast the car and do not feel bad about taking sales away from namebrands as most all do not sell manifolds any longer.

No, it wasn't at you.. And yes, i read your post. You have experience with it so you are in a place to talk about it. I apologize that it could have been interpreted as being aimed at you.
Its the idiots who just read one thing on a product and all the sudden are all knowing on the matter when they haven't even seen the product once. They spew BS that makes it a pain for those going through the thread. You gave a good review and unfortunately you got one that wasn't good as the QC is not very good. I read your post and found it informative, and I would be pissed if my manifold looked like that one, but the welds on my were pretty good and it fits a to4r just fine. My friend added an hks t5r with a vband adapter and had no problem, but another one of my friends couldn't get a 71mm Borg on it (granted he has an enormous t6 housing on it).

are you brett o_O and are u refering to mine ? its a t4. If not sorry I dont follow the forum often. There isnt very much of the original manifold left lol. enlarged the wastegate runners, cleaned out the poor cutting on the inside of the manifold , extended the manifold due the size of the borg warner.
which bw is that? and have picture how you extended the manifold?

It looks like he modified the manifold so that it fits further forward? I can't wait to see how your build turns out, it will be interesting to see how our cars compare as you have a bigger turbo, but I have more aggressive porting.
