La Prépa Turbo pour les Nuls ! Sleeper de Guerre !

Summary

La vidéo décrit les travaux continus d'un mécanicien amateur sur son projet de voiture, une Peugeot 205 GTI. Il explique les dernières étapes de la préparation du moteur, notamment le rodage des soupapes, le réglage du jeu de soupapes, et présente également la peinture personnalisée du cache-culbuteur. Malgré quelques contretemps, le projet avance et le moteur se rapproche de sa version finale.

Takeaways

• 😀 He is rebuilding a 1.9L diesel engine into a 350 hp turbocharged gasoline engine for his 205 GTI
• 😧 He had issues with piston heights and connecting rod lengths, requiring machining work on the pistons and head
• 🔧 He installed new forged pistons, a 205 GTI 1.9L head and had the head resurfaced beautifully
• ⚙️ He is adjusting the valve lash by measuring clearances and determining the right shim thicknesses
• 🔬 He calculated the required shim thicknesses precisely for proper valve clearances
• 🎨 He painted the valve cover black with slickers and clear coat, aiming for a clean but not perfect look
• 👀 He test fitted the engine and is very happy with how it looks so far
• 🙌 The bottom end is fully assembled, head work is nearly complete - major milestones
• ⏳ He is still waiting on some small parts like shims and an arbor lock piece
• 🚗 The end goal is dropping this built engine into his 205 GTI for big power

Q & A

What is the goal of the project featured in the video?

The project's goal is to modify a 1.9 TD PSA engine block with a 205 GTI 1.9 cylinder head, aiming to achieve 350 horsepower in a Peugeot 205.

What modifications are being made to the pistons in the engine?

The forged pistons purchased for the engine were shorter than the original diesel pistons, leading to an issue with connecting rods being too short. To resolve this, the presenter switched to 306 S16 connecting rods and adjusted the piston height in the cylinders.

What challenges did the presenter encounter with the piston rings?

The presenter encountered a problem where two piston scraper rings broke due to using a low-quality tool for inserting the pistons into the engine. This resulted in an additional expense of approximately 140 euros for replacement.

What is the significance of 'Flat Out le MAN' in the project?

Flat Out le MAN is a professional service that performed quality work on the engine's head, including mirror polishing and adjustments to ensure proper piston displacement within the block.

Why was there a need to adapt the tensioner and timing belt in the project?

Due to the modifications and surfacing done on the engine, there was a concern that the timing belt might be too loose. Adapting the tensioner and timing belt was necessary to ensure proper engine timing and operation.

What is the purpose of developing a new exhaust manifold in collaboration with a company?

The presenter is partnering with a company to develop a new turbo exhaust manifold for 1.9 and TCT cylinder heads. The motive is to create a readily available product for those wanting to perform similar engine modifications, as current availability is limited.

How did the presenter address the lack of compression in the engine?

The presenter resolved the compression issue by rebating the cylinder head, aiming for a volumetric ratio of 9.5. This adjustment was necessary to achieve the desired engine performance.

What was the presenter's approach to verifying the clearance between valves and pistons?

To ensure there was no interference between the valves and pistons, the presenter planned to assemble the timing belt and then check for any contact, considering the modifications made to the engine components.

What challenges did the presenter face while sourcing the correct valve shims?

The presenter encountered difficulty in finding valve shims of the right size. The variety of sizes ordered did not suit the requirements, leading to additional work in remeasuring and reordering the correct sizes.

How did the presenter plan to deal with the issue of the crankshaft bearing seals?

The presenter intended to disassemble and address a minor sealing issue at the crankshaft bearings, as it was pointed out by the person who supplied the gasket set. This was part of ensuring the engine's reliability and preventing future leaks.
