Performance improvements (or swap) with few parts?

Postby Giert » Thu Sep 07, 2017 11:31 pm

I know this has been asked a bazillion times, and there's a dedicated thread to what engines fit where and so on. But all of those seem to assume a steady supply of accessible parts to fit everything together. My Siggy's in Europe however. Parts are few and far between.

Even so, there are a lot of really cool builds around this forum, and I really would like to make mine stand out as well! At the moment there is a worn 4G32 in the enginebay, with a 4 gear transmission. I have recently gotten a hold of a 5 gear one, but would like to up the engine performance as well. Getting hold of a used 4G52 in good condition is possible. The 4G54 however was only sold in the Mazda B2600 up here, and significantly more difficult to get a hold of.

The way I have understood it, both of these should be fairly easy to fit, but precisely what parts would be needed, assuming I have absolutely no spare parts on hand and will have to order everything a few weeks in advance?

And further, how much of an increase in performance will I gain, and are there other upgrades that can be done in addition or instead of an engine swap that can be done with relativly few, or easily accessible, parts?

Any help would be greatly appreciated!

First step is find out if your new gearbox has a wide or narrow bellhousing. From there your can work out which motor to use.

Red (311mm) is narrow, blue (337mm) is wide.
