Sounds good for a 4 banger straight out the head lol good work man

[Billzilla]

Have you got something to straighten the airflow before the airflow meter?
Mine also used to idle nicely but drove like crap until I used a bunch of drinking straws to remove the turbulence in the inlet.

Nice work. Congrats on hitting this milestone. Yep, down hill from here.

[garvice]

Thanks for the kudos guys.

Bill, no I haven't got anything yet, though I am thinking of building an air box which will take air from behind the valence. Can build a straightening vane if I need it, will probably do the plate type though as it'll take up less room.

Hanging to see this car complete. I'd love to do some similar mods to my 510 but I couldn't bring myself to cut it up, would be easier starting with something like this.

[garvice]

Hey rollin, thanks mate. Yep it was easy starting with a shell like this. But now that I've done it, I wouldn't have a problem doing this sort of work to better cars. It's all just metal so easily fixed if you stuff it.

[tim510]

have you looked at a 240Z centre console to sit on top of the tunnell?

[garvice]

Haven't thought about that, was going to just carpet it. But I do have one in the z so might give it a go.

Well been a while since I've done much on the car and updated this forum.
I decided that instead of building new headers, that I would just modify the ones that came with the halfcut. Problem with the ones that came with the halfcut was that they basically came into two collectors right where the steering linkage sat. So I started by cutting out cylinders 1/4 to drop the bottom collector. I discovered that the top collector then missed the linkage in most of it's range, but still hit it in the locked position. I also didn't like how close the pipes were to the rubber bush of the steering linkage. So after rerouting the 1/4 collector and spending a bit of time on modifying the headers, I decided, stuff this and cut all 4 headers off close to the flange to start again.

I built a 4 into 1 collector and started routing the pipes from the head to the collector, only to realise that this was very hard to get the angles right. So for the third time I cut the pipes again and started at both the collector and the head at the same time so that I could get them to meet better. I didn't do equal length headers, but I did get them reasonably close in length. I also used some stainless 308ss mig wire but decided I would just use the standard argo-shield light gas that I had. It worked, but it did create a fair bit of splatter. Welding wasn't my best on the headers and my flapper disc was worn out when I was doing the final welding late last night/early this morning, so I didn't bother grinding all the welds down. I'll probably regret that latter on as some are near impossible to get to now.

Well all those words are basically explained in the last photo below.

Didn't want to use the extractors that came with the engine? They are 4-2-1 and will probably work better than a 4-1 in most cases.

[garvice]

Didn't fit Bill, it was this or log manifold.

Bugger.
They fitted in my Sprinter, I wouldn't have thought the engine bay in a 1600 would be a lot smaller ... ?

[garvice]

Mine came with jasma stainless extractors. The 2 into 1 collectors were under the frame rails. They would have worked if it wasn't for the steering linkages. In respect to engine bays though, that sprinter engine bay looks massive in comparison to the 1600 engine bay.

Can I please buy this for cheap cheap when all the hard work is done :D
