This car was bought by my dad when it was new. It was daily driven until 2002 it was stored to a barn for 5 years. In 2007 it was taken in to use as a wedding car in my wedding. In 2010 I decided to install EFI to it and had to make full restoration to it.
The was quite a lot of work to do, but I managed to build up the car one metal piece at the time.
Starting point in 2011:
In 2014:
In the beginning of summer 2019 I was finally able to drive the car with Megasquirt 1 installed with following features:
-Peugeot 206 1.4 engine throttle body with ~39mm diameter installed to 1 barrel intake manifold
-Peugeot 306 1.6 fuel injectors 156cc
-Volvo740/Saab900 fuel filter
-Ford EDIS4 controller and edis coil pack
-QSP fuel pump in tank with 3/8" feed and return lines
-36-1 trigger wheel installed to balance axle pulley
-Volvo740 2 wire bosch idle pwm valve (same as in Saab9000?)
Here is a picture of the throttle body and fuel rails:
And engine bay:
It was fun to drive the car last summer. Better throttle response, better startup, less fuel consumption, milder exhaust fumes and so on..
In the end of last year I decided to fit 7.2 cam, sport exhaust from swedish saabclub modified with larger mufflers and Megasquirt 2 for more precise engine control and sequential injection. And the car works even better than last summer. Exhaust produces less noise inside the car, more power and less fuel consumption.
Continues..

Very nice exhaust Anttik, great work how you turn your ideas with theoretical back ground in real solutions.
Great work, top performance.

Thanks Bonne!
On the last spring I made the 4-2-1 exhaust manifold with correct cylinder pairs: 1+4 and 2+3 cylinders are merged first collectors, where the primary pipes are about 85cm from valve and secondary pipes about 27cm to final collector. According to calculations from A. Graham Bell book manifold tuning RPM should be close to 4500, where maximum torque should be according to dyno testing results.
I made the primary pipes as short as possible, when manifold is located below the engine. Optimally 4-2-1 manifold should have primary and secondary pipes of same length, but I think this manifold has performance between 4-1 and 4-2-1, which should give little bit more low end torque than 4-1. And 4-1 would have less ground clearance. I made the collectors to the left side of the engine, because there is clearly more space.
And the performance of the manifold:
-Small improvement acceleration on 3rd gear in 3000-5000 RPM range
-Most quiet exhaust so far. No noticeable resonances. Not much difference on exhaust sound, but sounds nice
-Volumetric efficiency has improved in 3000-5000 RPM according to EFI mixture re-tuning. This means that fuel efficiency and power output should be improved in that range
I have been planning this manifold for years and it was hard work to weld it, but I am very satisfied with the result. It is simply better. |

Excellent work AnttiK, glad to see it works out fine.
Each time i am impressed by the quality of your work.

Exhaust divider was in use in 2024 summer. Little improved performance with 65cm primaries + approximately 65cm secondary pipe on the right and 85cm secondary on the left. Exhaust header work in progress to find more effective solution.
I have not seen any negative effects on exhaust 2-port solution except it takes more space. Engine sounds happier and mixture seems to be smoother according to 02 sensor readings.

Hi Gareth,
Of course Just give me your email address and I will send the CAD file to you.
I installed the Saab NG9-3 Monroe gas rear shocks to 96. Those were little bit longer than the original 96 V4 rear shocks, but those fit very well to 96 by enlarging the lower bush hole to 16mm and narrowing it. I drove with those about a couple of months this summer and thought rear suspension was too hard for my purposes even though I liked the improved handling on corners and motorway speeds. Then I decided to buy adjustable AVO rear shocks and now the car suspension feels even better |

Hi Antiik,
Project is looking great!
Would you be happy to share the CAD file for your flywheel?
Thanks

Duh! I was forgetting it's F.I. |

Fuel injectors are located in lower part of the manifold so there should be no fuel in the plenum, but probably there will be some fuel fumes in plenum anyway. |
| Derek | Posted - 01 May 2023 : 12:18:36
Good work. I suspect that modern fuel will remove the paint inside the box but it will be gradual and the engine will digest it over time. |

Thanks, I also think that now the total setup is better in every way than the previous version of upper manifold. Next step for the engine will be the cylinder heads with dual exhaust ports, but first I am going to repair at least the driver side door and the probably the passenger side. Already made one repair piece for door yesterday.
The intake runners are rounded inside the plenum. I fabricated the runners first and in that way was able to smoothen the inside of the runners properly. After that the runners were welded to plenum.

Really like the total set up and looks AnttiK, compliments.

That looks even more awesome than last time. The grey paint on the plenum that matches the heater unit visually ties it all together, very nice work.
