What fun your films are, it's great to see some 'sound and vision' here, thanks!

rebuild intake manifold

Wow you're skilled!

I'm very impressed indeed. Thank you for sharing your work with outstanding photos.

Hi hepe75.
What gear box you used original from Dedra or from Delta integrale?
And what clutch you used?



Regard Kiril

I use orginal gearbox(it's same delta integrale) but I change rear differential from Delta integrale, because there is TORSEN and Dedra rear differential not
Clutch disc 228mm(orginal 235mm)

and clutch assembly is 30% more stiff to orginal

Congratulations on the car and the job done! For sure a lot of money and expertise involved!
I enjoyed a lot viewing the pictures! Good luck with the car

and yes, the throttle should be in a different direction than usual

I do recommend that you spend more time on the header and try to improve the ratio of chord radius to pipe ID. Ideally you want a ratio of 2:1 or better - in other words the most generous chord rad you can get. I've tested several aftermarket tubular headers lately from turbo 4 cyl units and the pressure drop due to adverse bends is very high - near 50% in some cases.

I know that this is not perfect, but it has my own manufactured(first one ever) and the target is that it would be better than the original exhaust manifold is

As pre usual practice here my comments are constructive observations and not - criticism.

Without testing the original manifold you have no way of knowing whether yours is better or nor but be aware that it is easier to generate beneficial curvature with a casting than tube (in confined layouts anyway..) and it is a common misconception that pipe will be better 'per se'. It will not be if you have very restrictive bends like your layout has.
