Swift 1.3 DOHC into a Samurai

[Jeremiah]

because the gti bottom end is filled with high quality forged parts-crank rod and pistons. sami stuff is cast and cant handle any real rpm without the threat of throwing a rod out the side of the block.

Oh... well so much for being lazy / cheap then  I've been eyeballing the 1.6L upgrade myself... how does the DOCH handle the low RPM stuff?

[Cy-Zuki]

Velly Interesting!

Ditto above - OK so it revs but what is the torque like compared to normal Sammi engine?
I suppose the next question would then be: what is the torque compared to a 1600?
I would imagine the torque would be less than the 1600 and may be even less than
our old friend the Sammi???

Am likely to be mahoosively wrong, I'm just guessing.

i cannot speak for lxer96, but i know my gti powered samurai has far better low rpm pull than any 8v 1300 i have ever had.  please note that i run carbs not efi. 

[lxer96]

It simply outperforms my old 1.3 8v in every way.  Where my old engine would kinda sluggishly chug along, this one doesn't stay in the low revs long enough for me to notice a loss in torque if there is one.  The throttle response is 10 times better.  I also have a 1.6 8v Sidekick and the GTI in the Samurai feels alot more powerful.  Might have something to do with weight though. 

GTI  100HP@ 6000rpm 83.2ft/lbs @ 5000rpm
1.3 8v 60 HP @ 6500rpm 76 ftlbs. of torque @ 3500 rpm
1.6 8v 80 HP @ 5400rpm 94 ftlbs. of torque @ 3300rpm
1.6 16v 95 HP @ 5600rpm 98 ftlbs. of torque @ 4000rpm

There's a swift in my hood for $700 *drools*

[lxer96]

Just to add, it also passed GA emissions today!

[ka4yqi]

All right on the emissions. Did they look under the hood? Right now we dont have to be inspected, but its coming.

[lxer96]

Nope.  I'm hoping that the "1300" on the valve cover will throw them off since it's still a 1.3l

If anyone else wants to do this swap I have 2 running GTI motors still in the cars with harness and computers that I may sell.

What condition are the cars in?

[ZukiJon]

You have to be at 5000RPM to go 85, even with the DOHC?

5K is nothing for a GTi, I had one in high school and used to spin it alot higher

[Jeff@TheQuadShop]

One is totaled and the other is disassembled.

They make peak power at 6500 rpm with redline at 7000.

I know for a fact it'll go over 8K and hold up, but it really isn't making much more power if any at that point. I was hard on that car, and it never gave up. I was a kid, whatdya expect, I had fun but know better now. I'd love to have another as a DD.

I have one as a daily driver that is super clean and has the rare Suzuki 7 spoke alloys.
