620 sr20det

[Datsunsr20]

Hi guys, 

 

Recently purchased a 620 truck and wanting when everything is ready change the engine. 

Ive a sr20det out of an s14. My main issue is what needs changed from the gear box back to make it work. 

 

Axel need changed? 

Just the differential? 

 

Any help or links would be great! 

 

Thanks 

Phil

I offer mounts to make this a bolt in swap fitment wise.
You need to flip the center link and shorten the stock driveshaft for the longer SR transmission. 

 

My mounts, I have engine mounts, transmission crossmember, alternator relocation, fuel pump and MAF brackets.

 

Center link flip

Do you know what lsd would be best to fit?

There isn't really a goo option for the stock H190 rear.

 

Early Toyota 4x4 axles are about the correct width and have a large aftermarket following.

For the cost of a ultra-rare used Datsun LSD, you can do an entire Toyota axle swap and have your choice of limited slip, Detroit, air or electric locker or even a spool. Gear sets for an 8" Toyota diff cost about $200 and bearing kits around $100. Disc brake kits are available too, but most are junk, though there are a couple kits that work well and have a price to match.

Id imagine these parts aren't available in the uk!

Id need to know which axel is needed too? That might be hard to get!

Early Toyota 4x4 trucks and 4 runners up to 85. 

Later year axles can be shortened.

Good info here - https://www.roundforge.com/articles/toyota-axle-widths/

 

Edit - this is info for north American vehicles. European vehicles had different names and more models to choose from.

WMS is "wheel mount surface" so when it says WMS to WMS, it means as measured from those two surfaces.
