Hi all,been around road racing for awhile with open wheel cars up here in Canada,but now getting into a full body car with a partner and our two sons.
Have acquired a 93? Swift that has already been preped and spent time on the track,but needs engine reassembled with thoughts of adding turbo at this time.
I have boxes of parts,I beam ARP equiped rods,race style pistons,dry sump system.
With what I believe is a G13B engine and not having any experience with Suzuki before,whats the best place to source engine build specs,ie bearing clearances,piston clearances,bore specs,etc.
I can and will add some info on what I have via pics and description.
The engine is not my biggest concern though, what I am wondering is about the trans, is the stock trans suitable for road racing a turbo inducted motor?There apparently is a L/S diff with a set of racing gears supplied,is the stock trans strong enough for a L/S diff?
This should be an interesting/fun build and am hoping for some valuable information from the forum to help us along,thanks in advance.
BTW, this car WILL be on the track this year,we are primed and preped to go forward.

Looks like you have a lot of work to do there.

The gearbox is the weak link in these cars, if its NA then you will be fine, don't go aggressive on the clutch, something with a little squish to absorb some driveline shock will help you to not break things.

There are larger gearboxes you can use if you want to turbo it and still be reliable, not quite a bolt on but not too bad, does require a different flywheel, clutch and LSD.

You should look up codyb76 on Teamswift.net as he is in Alberta, has spent a lot of time wrenching on these cars and oval dirt races one, he's a wealth of knowledge especially in your part of the world.

Thanks very much.What do you mean by NA gearbox?And what are the other options as far as other boxes,are they factory boxes just from a different year?

NA - Naturally Aspirated, it's the torque that breaks these gearboxes, remember they were designed the gearbox to mate with 55hp 3 cylinder and 70hp 4cyl engines.
They made the diff a little bigger for the 100hp twincam but everything else is pretty much the same, we call this family of gearboxes "small frame" as they have a 60mm centre line between the two shafts.

The other range of gearboxes is the Large frame which have a 70mm centre line, this means thicker shafts, bigger bearings, bigger teeth on the gears, these boxes all have a cable shifter and came on swift sedan, Aerios, sx4's etc, the general opinion is about 180hp max on the small frame box and roughly double that for the large frame box.

Have a read up on this site, there is a ton of info on the swap, it's worth doing right from the beginning unless you are going to stay NA.
