Single Point Vit Injection\Supercharger

[rammer]

Im dead keen to supercharge the stock carb 1.3, ive got everything else sorted and have the right tools and the right people to get it done, BUT.... how hard is it to fit the single point vitara inj., what is involved and what extra\other parts should i source for the blower application.

I believe the entire vit tbi manifold just bolts on to the 1.3.
So wiring up a computer and the plumbing is all.
Should be fairly easy.
But I have not done this myself, so its just 2nd hand info...

I have turboed with the 1.3 tbi setup was easy and very effective done a lot of kms with this setup. I have seen quite a few tbi setups around now. The inlet manifold bolt's strait on so wire it up away you go, that easy. Other people on the board have run a supercharger through them.

tbi??? me no unnastand??? also is it the whole manifold that bolts up ( to the side of the block) or just the throttle body etc? also do i require some sort if new fuel pump, either in tank or inline? just wanna get it right 1st time so as not to have the rig in bits for too long. can anyone think of anything else

tbi = throttle body injection = single point

yes whole manifold does bolt to side of 1.3 block

but I don't know if you have to use entire manifold from vitara, but guess you do.

efi needs a higher pressure pump, so I guess tbi does, but dont know, sorry

may do this conversion myself one day.

tbi means throttle body injection. you wil need to run an electric pump either intank or external i run a vl commodore pump. also you need to get an 8v injection manifold and throttle body. the 16v inject are different to the 8v and wont work unless you swap too the 16v head

[Santos]

I've thought on this and played around with some different configuration

Wouldn't it be ideal to change the whole top end? After all a 8v G16A head would have bigger valves as well as cams designed to take on almost 25% more air into the combustion chamber

(This is crude i know but just so you can understand my reasoning i have provided the following equations

1.3L = 1298cc
1.6L = 1598cc

1.6L(1598cc) - 1.3L (1298cc) = 0.3L (300ccc)

Therefore
300cc/1298cc x100 = 23.11% )

Which would probably be more ideal for Forced induction, you could even add a thick copper plate gasket to lower the compression when you swapped the heads. Can't hurt.


But seriously what Supercharger would you use...?

The toyota one with the electro-clutch would be good i suppose good cause then you would have idleling issues as you could have a missile toggle swith to get 'boost' (Ricer run ricer, ricer run! ) you could also rig the switch to trip a short in the ECU into running the mixture at it's richest setting. A 1200cc per revolution Supercharger (hey i read it ok, don't be hating) like this would probably mate well with a 1.3L

The suburu mini super on the other hand is small and easily tucked out of site it's suppose to fit to a 600cc but designed to work up to 8000rpm ( i could be wrong here but everything i read on Kei class japanese cars points to motorbike rev rages) so with the proper gearing you could probably have it doing the same amount of rotations at 4000rpm


Anyway hope it helps i looked into it from a theory point of view last year when trying to way out most gain on a second zook for Frazer Island

and as Christover says it's all second hand knowledge but i like to share as it's a long way off for me (Tequila is still a little Cultus greedy)

Valve sizes

Sierra 1.3 8v

Intake 36mm (4)
Exhaust 30mm (4)

Vitara 1.6 8v

Intake 36.6mm (4)
Exhaust 32.5mm (4)

Vitara 1.6 16v

Intake 29.2mm (8)
Exhaust 25mm (8)

There is some info on the 1.6 8v TBI to 1.3 swap here www.suzukiinfo.com/

Firstly, Santos I can definately see what you're saying about the 8v head, the extra flow capacity would definately be benificial in a forced induction application, but I had never heard of fitting an 1600 8v head to the 1300, can it be done? Not that I dont trust ur vast zookiological knowledge I'd simply just never read of this before.

Secondly, I would more than likely go with the little scoobie blower, purely for the ease of fitment, small size making it easier to conceal from the "you know whos", and the minimum outlay ( hard work gettin thru the week on trainee real estate wages). I read in another post that Sam used this blower, pushing 20 pounds out of the little thing into his motor, this also leads me to beleive that if i am only to run my planned 6-7 psi, it could be done quite easily and be no so detrimental to both motor or charger, I will be keeping intake temps to a minimum with a front mount 'cooler and running the new caltex 98RON fuel so all should work well.

Thankyou very much to all who have replied as any advise, whether 2nd hand or not, is better than what i had.

interesting... i think i might use this info

The heads are interchangeable .. I had a 1.3 head one a 1.6 block bolt on swap ..

[ca18escort]

Also remember that because the engine is a 4 stroke that the intake is only once every 2 revolutions hence the 1300cc will only realy be 650cc per revolution this is why the subi charger works. Now just as a point of reference from the information that I have the subi charger is an AMR 300 which means it is only 300cc per revolution. You can get an AMR500 but they are from the Nissan March super turbo engines and are quiet rare. The SC12 from a 4AGZE would be the best setup from a boost point of view. Not that I am doubting Same but to run 20psi using an AMR300 on a 1.3 zook engine you would have to run the blower to around 4.8:1 ration which means if the engine is only reving to 4000rpm that is just a shade under 20,000rpm which in my limitied experience will see it at the very least melting the teflon off the lobes.

The other option is that he means 20psi absolute which is in fact only 6.3 psi.

Thanks Love_mud,

How much should i expect to pay for a 1.6 head? Cant forsee it being a cheap purchace!
Where can i source a 1.6 tbi setup from? I have decided I might get this sorted and running as a first step. Might be a good idea.
After this is done the rest is the easy part, mechanical I'm sweet with, electrics s**t me to tears.
Also Im not really that keen on the stocker ecu running the whole shebang, i want to try to get this setup to last as long as possible, be reliable as it can be, but also make the power that i am after what aftermarket cpu do you guys use\recommend.
Looking towards a fuel and spark cpu only. microtech?? haltech??
Or alternatively will the stocker suffice.

ca18 escort can you please explain what is meant by ABSOLUTE

[-Mick-]

std ecu would probably still fuel it on mild boost... ie 5psi

[ca18escort]

You have two scales of measure the first is absolute - this is where you say that atmospheic pressure is 14.7 and anything about that is boost. The other is guage which assumes that atmospheric is 0 psi. The only difference is that you have to add 14.7 psi to the guage reading to get the absolute reading.

talk to mud4b as he had the scooby supercharger (i think he had efi as well)
