Hi everyone!

So I just finished the courses! And now I'm in the actual Work Examples of the Course mainly focusing on the 4G63 engine because that is the main reason I bought this course. I have an 97 Eagle Talon Tsi FWD Automatic and I really like that the build in the video is going originally my main goal was to just build a complete stock engine but since I'm doing a complete engine overhaul I might as well just do everything all at once.

Or what do you guys think? With that being said it would be amazing if I could get all the parts listed in the video so I can just look into them and get them. I want it to be a street build in case anyone is asking!

Thanks!

You're fortunate that there are some very eperienced chaps here for that engine.

It would help them advise if you could clarify a few things,though, such as...

the obvious is the power level you'd like?

What are you looking at doing for the transmission, if keeping the automatic it will have torque, power and rpm limitations as stock, and may need some work for any significant increase in and of the afore-mentioned. I know Shota has used an auto' for sprinting, but don't know the version or what he's had to do to it.

With an auto', depending on what you're looking at using the car for, you may need to balance available torque converts' stall speeds against the lower rpm torque and boost building characteristics. If it's just for "rolling", or as a quick street car with a bit more zap, that won't matter as much, as you'll rarely be making hard starts, especially with stickier tyres that could handle a lot of torque.

Another factor is your budget - there is an old expression "how fast can you afford to go", which in this case may also come down to what you want/need to carry over.

When you've got the basic idea on what you want to do, you can then look at sorting out the parts required - with some there may be months of waiting - and I'd suggest looking for, at least a short block but a long block is better, to start with because if you use that as the base you can source the parts required to bring that up to spec', not only does it minimise down-time for the car, but it means if there's a problem with what you have, such as it already being bored and the new pistons not being suitable, or bearings being the wrong size, etc, you aren't out for what you'd already bought and won't have the additional down-time.

Forgot, there are some variants of that engine, for different markets and applications, so it may help if you have any more details on it, specifically, as some of the US versions are quite different from what they will have in their domestic markets..

Ok sounds good I think what I am going to do is just disassemble the engine completely and look at what was the issue for it failing on me. I believe that it was a head gasket blown and I have a whole thread dedicated to this engine in DSMTuners.com

As for the transmission I am going to just rebuild it as well because the people in the forums have told me it's best to just keep it automatic due to me being such a novice. Which I completely agree with them.

For listing parts I will just look into it when I make sure the engine block did not go soft or heads as well.

What do you guys think?

Hi. In my opinion the wise decision would be based on the goal of your vehicle rather than just copying the spare parts list. There are plenty of parts combinations that fit the best for every purpose asvlong as you know what you want to get from the engine. 4g63 is well known engine and everyone would be happy to help you with most efficient built...

Yes that is what I was thinking. I think I will just rebuild it stock for now and just make sure it runs good for a year ir si and then decide down the line if I want to actually put performance mods in it.
