dont waste your time on it wait for a while and upgrade to td04 instead you will want to upgrade anyways after that
Hey @Jay !Getting back to the initial question, you will notice a slight power increase in most aftermarket CT9 manifolds due to the improved flow of exhaust gases compared to the more restrictive standard item. Also expect a better spool up and power band as well. So long as you choose a reputable fabricator you should see a higher degree of reliability too.
WEPR, Zisco and Racetech are all common options, if you bang the maker into the search engine there should be a few feedback threads on here to read.

@Jay which td04 kit with external waste gate you suggest? I want a solit exhaust. Nothing that cracks easily.I do think you would be much better going for a td04 turbo and kit.
What exactly do you do when forging the engine? Cylinder her last rectification with new pistons and rods? More? What parts docyou suggest? Thanks.For the parts and labour involved that's pretty decent value to be fair.
You could compare it against converting to a TD04 kit. Basically the same job, just add a turbo to the list. Stacks more potential.
So long as you don't go silly with boost there will be no necessity to forge and you should be comfortably in the 180-200 bhp region. Can always forge up and throw more boost in at a later stage if you get bored.
I hear you Blitz it’s practically impossible to find. When I drive this car I like to feel the boost add 2500. The 4efe would start pulling at 3000 RPM. I would rather get the manifold with the external wastegate and a hybrid stage 2 CT9 kit with the oil line for the turbo and the modified metal water pipes. It’s OK for me to go to the shop and fix the hot pipe. It will also be OK to modify the FMIC pipe. The Corolla has more space between the engine and the radiator. I don’t think it will be necessary to change the radiator. What do you think?i've always had a soft spot for the ct9 turbo, especially a good hybrid ct9 unit.
i guess you'll have to shop around to see who is making a stock replacement exhaust manifold and matching downpipe...i'm kind of surprised wepr doesn't offer that option
and i can understand you wanting to keep as much stock as possible--radiator, oil pipes, water lines, etc...
the racetech one looks decent from the pics, however, its external wastegate with half radiator...they do have options there though...., but i would suggest that you specifically inquire that everything else will be stock fitment, apart from the manifold and downpipe,,,the last thing you want are surprises when trying to fit up
whatever you do, avoid those cheap knockoffs
if you could find good condition JAM ct9 manifold and blitz downpipe you would be covered it seems, but that's like winning the lottery nowadays
@SKINY I want to find more information about the turbo you were talking about. @Jay I have been driving tonight lower RPM and I like the pleasure to feel the boost at 2500 RPM. My actual dream would be the 4WD from a Corolla ep85/95 and that would help to enjoy A powerful setup. My problem here in Italy that nobody has experience with this engine. All I have achieved with this swap was my hard work and all the information I got from you people. I spent a lot of money and right now I enjoy working engine with the working air conditioning. My tuner wants to set up rhe Det 3. I got enough information to do it by myself and save the money so that I can bring the car just to be mapped. But before I have to change the exhaust and I still haven’t decided the ride to turbo for my need.I would tend to agree. You have a bit more elbow room in there. Can you measure the distance between the cylinder head and radiator just for comparison?
As for the CT9 versus TD04 debate there's countless pages on the topic here. Can't really add anything that hasn't already been said however if the difference is only a few hundred $$ put your money on the horse that's got longer legs
