I am pretty near completing the design/deal on a cam driven SuperCharger kit (DIY). It will mean installing a set of race cams, the intake cam having a Hex drive which will run the SuperCharger. To complete the install I will need to finalise the mounting bracket, move the coolant tank, decommision the EGR valve and measure/cut the blower to TB pipework After that its ECU and Injector work.

After that its ECU and Injector work.

Funky monkey!

What do you need to tweek with the ECU to work with a supercharger (out of curiosity) - does it need to know about the boost hardware?

The stock ECU configuration will work with a SuperCharger but you should monitor the fuel system to see how it is performing under boost conditions.

So the idea is after the SC install to determine are the stock injector performing OK, can the stock injector delivery be improved, should I/dare I add Extra Injector Controllers (EIC's).

Some useful information HERE

Speedster, I'm sure that there are a number of members here that would be very interested to hear more about your project! Which sc are you thinking about using? Can't wait to hear more! Rob

Which sc are you thinking about using?

I reckon so too
I am trying to contain myself till I get the actual kit and a clear installation strategy

I am going to use a RSM Racing Vortech SuperCharger Kit. RSM are bolting these onto 2.2 Ecotecs in the US and Canada.

To quote from their site
60 HP gain, complete bolt-on install. Kit includes
Supercharger, BOV, FMU, all brackets and oil
lines, air intake pipes, silicone adapters and
filter, all bolts and accessory belt, installation
CD. No extra parts needed for the install, and
works fine with the stock engine/transmission.

Obviously the kit does requires some custom work to attach to the VX220 e.g. its going to be cam driven.....

[Robski]

Sounds interesting! How much work is involved in changing the cam shafts on the vx? Also, I presume that the 60bhp gain is on the standard lump so with new cams should be more.... ...and then a remap..... the bhp starts to stack up! From my reading on the subject the inlet manifold is a major weakness - Ricky's experience with the Delta kit which uses a modified stock intake manifold. Does the kit come with a new intake manifold? If not, perhaps sourcing a GM one designed for their sc engine might be useful..... Good luck with the project and let us know how you get on! Rob

[Ricky2772]

So now you are using the Hitec kit, based on the 2.0 engine?

Is that a dynoed 218 HP? I know you have the Komo-tec backbox and a exhaust manifold that would give something over the standard stuff.

Also, have you considered for ex the piper 266° cams. Or is the wise way to only increase the pressure?

it's the delta kit optimized by Hitec (extra injectors repositioned, ECU remapped)
yes, 218 dynoed by hitec.
so far the power is well enough for my needs and skills...eventually I will resort to a smaller diameter charger- pulley

Ricky2772 some Q's 4 U
Where where the Extra Injectors placed?
Does the replacement manifold you are running with have provision for them or did you have to cut it?
What size Injector did you select?
What are you using to control the Extra Injectors fuel delivery? I assuming your not getting any puddling. Any details on the amount of fuel you are delivering on the standard and extra injector?

Not a lot is you are proficient with a socket set and are nimble fingered. If this is your first bash at changing cams I would suggest either get somebody who has experience to help or pay your trusted local engine shop.

Also, I presume that the 60bhp gain is on the standard lump so with new cams should be more....
...and then a remap..... the bhp starts to stack up! 

Correct, but you need to remember the stock engine has its limits and you do have boost and fuel system ceilings. A remap should def. be done.

From my reading on the subject the inlet manifold is a major weakness.... Does the kit come with a new intake manifold?

That depends on your objective. The stock manifold will happily deliver fuel for 200+ and before you reach its limits of around 280 something else in the engine is going to give. The kit will utilise the stock manifold. Of course changing to an purpose built manifold is sure to assist. I will be spending my hard earned cash on the initial SC set-up Like to see the manifold on the 2L SC unit though, to see if it actually does differ from the Z22SE

(extra injectors repositioned, ECU remapped)[/quote] Ricky2772 some Q's 4 U Where where the Extra Injectors placed? see pic Does the replacement manifold you are running with have provision for them or did you have to cut it? originally plugged into the plastic manifold, not anymore due to detachments and potential disaster... What size Injector did you select? ask delta. What are you using to control the Extra Injectors fuel delivery? the additional ECU unit.

Piccy of the 2.0 ...clearly a metal inlet?!

[#2177]

yes, aluminium, all of that is used by the HITEC conversion. #2177

meaning.......... it bolts right onto the 2.2 Ecotec, correct?

[vocky]

Sure does

[speedster]

If you had the choice would you swap out the 2.2 Ecotec for a brand new SuperCharged 2.0 Ecotec or SuperCharge your 2.2 Ecotec? Wonder what you could bring a 2.0L SuperCharged Ecotec up to. Its 205 horses in standard trim, if I remember correctly

It would be nice to think the engine swap would be simple, but the ecu, clutch and flywheel will all need attention to work in the VX. I know at least one guy with a speedster who has bought a wrecked saturn ion redline engine (the 2.0sc) to see if he can fit it.... We shall see how it turns out!

You are correct, the std 2.0sc engine has 200bhp, but more importantly, 200lbft! Swapping the sc pully will up that a fair bit, too!

Cheers, Paul.

[speedster]

Thanks Paul, Looking at options and doing the maths..... till somebody figures out the swap, rather than buy the tune shops expensive SC kits, wouldn't it be cheaper to but a brand new 2.0L SC in a crate and use it as a donor for the 2.2 NA i.e. take off all the necessary SC components and attached them to the 2.2 in the NA? Why would I pay 4K GBP for an SC kit when I can get a 2L SC in a crate for around 4K USD?

If you're thinking about doing that, why not buy the SC from a wrecked car (saturn ion redline, or cobalt ss) in the states? Would be cheaper still!

Cheers, Paul.

[paulf-cam]

In case anyone is interested, i'll post this < link > to a sweedish guy who has swapped his 2.2 for a SAAB LM850 turbo engine from a 9-3 (i think).

This is another engine which is based on the 2.2 lump and will drop in - lots of interesting pictures even if you can't read sweedish (i can't either)! Thanks to Dude for showing me this...

Note the huge boot modification to accomodate the crazy big exhaust manifold ;-)

Cheers, Paul.
