1.6 Vitara Motor in Sierra???

[Reedy]

I know this may sound like a silly question to some but I can't remember for the life of me if a 1.6lt Vitara motor (block) is a straight bolt in fit to both the head and gearbox on a 1.3lt Sierra??????:crazy:
Any help will be great!!!!!:thumb:

pretty sure they are mate, it's been done a million times. Might need a adapter or something perhaps but it's doable. try Suzuki Parts and Service Specialists based in Australia (http://www.suzisport.com)

Check this before doing, but i think the 8v bottom end bolts up to the 1.3l gbox & the 1.3l head bolts onto it.

Ive just put a 16v in mine, you have to use an adaptor to bolt the 1.3l gbox to it, I dont think the top end is interchangable

Why use the 1.3 head? Is it just so that you get to use all the same manifolds etc?

[GRPABT1]

It's higher flowing I think, possibly because of the smaller chambers, also could be for more compression. Ideally you would want a twin cam GTi head.

Thanks guys!!!!!:thumb:

The reason I'll be using the 1.3lt head is because I might be getting my hands on a 1.6lt bottom end in good nick but with no head and so on!!! It will also be handy with if I can use my extractors and standard manifold as I have a 32/36 Webber and a 40mmIDF Webber sitting in me shed that have adapter plates to suit the standard manifold which would go great on the 1.6!!!! It's just that if it is not a straight bolt on fit to the gearbox I will just rebuild the 1.3 as the poor old girl is getting very tied and I need to be able to do it over a weekend as I need it to drive to work all week and I also dont have the money to waste on adapter plates!!!!:(

So is the 1.6 block a straight bolt in fit??????:crazy:

On a side note, be aware that the 1.6 block is taller therefore the air intake will rub on the bonnet.

No it wont.
The only suzuki motor that's tall enough to rub on the bonnet is the vitara 1600 9 even then you can get creative with the mounts to loose some height.
A 1600 with a 1300 head, 1600 single point, 1600 multipont from a baleno, baleno 1800, will all clear the bonnet. Even a 2 litre motor will fit under the bonnet of a non-bodylifted zook.

According to Suzuki's data the 1.6 8v and the 1.3 8v heads have the same size chambers (32.2cc). I have never come across anyone who has disproved this yet. The 1.6 also has a larger exhaust valve (32.5mm compared to 30mm) and intake valves (36.6mm compared to 36mm) which has been shown to be a good mod on the 1.3 head. The 1.3 ports are slightly different though.

The Vit sohc 1.6 16v head will outflow the dohc 1.3 16v head unless the 1.3 has been subjected to some extreme porting work etc.

Almost, the drivers side mount needs to move forward 23 mm- you can get away with a flipping the rubber mount and using a piece of plate with a second hole drilled in it though...put the engine over the hole and it'll become clear.
The 1300 starter motor needs a bit ground off it to clear the block.
Theres two extra mounting points on the block that aren't on your bellhousing ( roughly at the quarter to three position if youre looking at the clutch.)
You can weld two tabs to the bellhousing, bolt the lot together and drill the tabs. Alternatively if your a good shot you can drill the boss on the block and tap into the bellhousing, a decent sized bolt will still be required.

Use the 1300 starter, flywheel and clutch plate.
If the motor came from anything except a vitara, you'll need to use your sierra clutch cable bracket, drivers side water jacket (the thick pipe that runs out the back of the water pump) and a carbied vitara rear water neck.( the one under the dizzy.

If it's vit motor the dizzy will work, otherwise you'll need to sort the dizzy out- a right angle drive, a hole in the firewall, a late 80's astra dizzy (theres a couple of others) or you can use a late model baleno with coil packs on the rocker cover.

You'll need a fuel pump and a a thermo fan.

For what it's worth I wouldn't bother with a 1300 head on a 1600- not when you can get a late model 1600 baleno motor for a grand- no carby, coil pack injection, good power from a stocky, well behavied, no modified head gaskets, computer does all the work no carby and did I mention NO CARBY.

There are a few things you need

1600cc bolt-in (http://www.puresuzuki.com/1600cc_bolt-in.htm)

[GRPABT1]

Just another thing in case nobody has told you, get the beleno or twin cam gti motor cause there is no carby... just in case you haven't been told that 3 times already. lol

:thumb: Thanks guy's!!!! With the intake rubbing on the bonnet that is gunna bo no dramas as I already have a 2" cab lift!!!!! As I said I was going to run the 1.3 head cos the motor I am looking at is just the bottom end and I was going to do the head work on the 1.3 head myself to flow better!!!! And also running a carb suits me better as I have a few different types that are lying around that will suit so there is less expence there!!! But anyway I think I will either rebuild the 1.3 or go with the other idea I had and put in an L20B Datsun motor running an auto box, I've done me measuring and it will fit nicely. I just thought the 1.6 Vitara motor was straigt forward by the way some poeple say but if I need to start modding things I might as well go the whole hog and do somthing different!!!!:thumb:

[zauronus]

i have this conversion in mine, i wouldnt go there if i did it myself, personally im looking at a 4agze conversion in the near future, so not worth the hassles in my opinion

I think for ease and cheap fitment and bang for buck you can't go past a G13b with boost. A motor can be had stock for $1000 tired, $1000 rebuild, sc12 toyota supercharger for $500 re-built and there you have it. That would give you enough power to start breaking driveline components if you give it heaps.

[scrimegour]

tho can you do that fit a charger to a sierra engine ? wouldnt it destroy it ?

[GRPABT1]

The GTi gurus reckon up to 6-7psi is safe on a stock GTi motor with 10:1 compression non intercooled. I would do a rebuild with some head work and maybe a thicker gasket to drop the compression ever so slightly but not alot as I like to run some static. Then I would use an intercooler with about 10psi and a blowoff/bypass valve to vent boost on idle.

Also I'm pretty sure the stock sierra 1.3 runs less compression than the GTi so it would suit boost even better.
