How good are the zisco mild steel ct9 manifolds and do you receive significant gains compared to other manifolds ?

Zisco make amazing products make. Manifolds are strong and reliable, you'll get better throthle response and the BHP gain - depending on your turbo, boost you're running and the exhaust/downpipe.

I'm talking from the Experience here - my starlet used to have Zisco exhaust, downpipe + manifold and I'm well happy with their quality!!! I was getting FULL boost by 3K rpm, running 177bhp on a standard CT9 and AUTO gearbox.... making 14.5 sec using road legal tyres...

dont waste your time on it wait for a while and upgrade to td04 instead you will want to upgrade anyways after that

TD04 on a standard engine? a good way to blow the engine up - pure lottery considering the age of these cars. Oh and forget about a quick spool and full boost at 3K rpm. In my opinion CT9 is good enough up to 200 bhp and is a great fun to drive in city. Where is TD04 is more suitable for the motorways and can be pushed over 200 bhp, but gives more stress to the engine - as you'll be driving at high rpm - might as well buy a Civic. And if you have the money - I would rather go for a Garret turbo...

Plenty of people with TD04 and blown engines - great fun for a month or two and then a complete engine rebuild... even with good management...

ive been running td04l at 1 bar (215bhp) for over a year now and the engine is still going strong, if going td04l do a compression test first to see if you have a good engine to start with.

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.

Hey @Jay !
I’m unable to find any of these exhaust manifolds. Can you help?
 
i've only ever dealt with Sacha/wepr so i'll comment in that regard...i've had both stainless and mild steel kits, very durable items at competitive prices, safe shipping, excellent before and after sales service.

maybe other members can give feedback on the other traders mentioned

Thank you all I spoke to Sacha He explained that in order to get a custom exhaust manifold on the ct9 The water pipes from the turbo will have to be modified such as the oil pipe that it is included in the kit that he sells call Sole with the downpipe. I will also need to change the radiator with a half radiator from a Civic. I will have to buy an external wastegate. The downpipe will have to be welded on the exhaust. The turbo hot pipe will have to be modified. We are talking about $1100 for the parts plus labor to modify steel.
I was hoping I could replace the exhaust manifold without the need to change everything around it. This job is needed to gain a few horsepower without changing the turbo. Is it worth it? Of course changing the turbo would mean getting the engine forged. My goal is to get 180 hp for a daily use.

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 do think you would be much better going for a td04 turbo and kit.
@Jay which td04 kit with external waste gate you suggest? I want a solit exhaust. Nothing that cracks easily.
I read a lot about the td04 and the only thing I don’t like is that boost starts to pick up around 3200/3500 rpm. Ct9 starts pulling at 2500 rpm and the engine does the rest on top rpm. I like the feeling that it pulls low. I don’t like drag tuning that gives everything on top with limiter kicking in and destroying tires. Especially because I’m unable to go 4WD with a Corolla ep85/95 aa it it is only RHD.

the guys here have a ct9 exhauat/doenpipe/stage 1.2.3 ct9 turbo kit that I was considering. What do you think about it?

I bought the SLD speed limiter to get rid of the 112 MPH limiter. Hope it will work without modifying my cluster functions.

What exactly do you do when forging the engine? Cylinder her last rectification with new pistons and rods? More? What parts docyou suggest? Thanks.
 
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

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?3ECC619F-441E-4197-902F-297219050D1F.jpeg

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 ;)

How about a tf035, still quicker spool than the td04 and should see the hp your looking for
I've a tf035 kit there and il be happy at 180/190 hp area

@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.
