Default Project SX4 VVT conversion

I'm planning to modify my stock july 2008 (type 1) SX4 to type 3 (VVT 2009 onwards). If you are wondering what is type 2 SX4 it was mid 2008 - mid 2009 as per SX4 parts catalogue.

Homework that has been done:
1. I was not sure if identifying the delta (type 1 v/s type 3) using SX4 parts catalogue was the right thing to do, but I did a manual scrutiny to identify the changes. I will upload a excel sheet with changes once I'm done.
I need experts at team-bhp to label the mandatory components as important.
In short the functional components with delta are:
1. Cylinder Head
2. Emission Control
3. Air Cleaner
4. Throttle Body
5. Crankshaft
6. Cam Shaft/Valve
7. Cam Chain
8. Oil Pump
9. Engine Electricals
10. Compressor
Will list part numbers and roles for above 10 components shortly.

2. Modifications will be done in stages. After all the parts-to-be replaced are identified, I intend to get the "important and critical" functional components replaced first.

3. Other cosmetic changes will also be done - Type 3 suspension, Door sills, trims, accessories, rear seat head restraint, front "new" grill
I have done the homework for this and suspension work adds up to 6437 for MGA parts 41601M55K52, 41602M55K52, 41111M55K21, 41311M55K01, 41800M55K02 (excluding labour). This is a softer setup in type 3 and should improve harsh ride quality.

REAR SEAT HEAD RESTRAINT - (86401M55KD0-W8R) 514.00 x2 = 1028
GRILLE, RADIATOR UPPER (BLACK) 71740M55KB0-D51 = 2946.00
COVER, RADIATOR UPPER GRILLE 71743M55KB0 = 162.00

* Optional
TRIM FRONT DOOR RH 83710M55KB0-HGT = 2261.00
TRIM FRONT DOOR LH 83720M55KF0-HGT = 1954.00
TRIM REAR DOOR RH 83730M55KL0-HGT = 1884.00
TRIM REAR DOOR LH 83740M55KL0-HGT = 1882.00
(if 4 doors need to be replaced)

I am yet to identify part number for Backlit Steering Audio Control introduced in type 3 SX4 (should be less than 2000 IMHO)

I have installed a sunroof, and at the time of resale if buyer does not want the same, I can replace the whole roof (65111M55KA0) for 4338 + painting cost. Sunroof (WEBASTO 300) costed me 42k including labour, so I would not let it go for peanuts.

SX4 parts manual is 99000M24120-643

All helping hands / suggestions welcome. Please feel free to fine tune the scope and optimize the project.

. This is going to be one herculean task, and I don't think it would be worth the time, money and effort. Why dont you sell the car and buy a VVT model, brand new.

Reliability and resale value is also an issue after the effort expected to be spent on such a build. It will be easier to exchange you existing car for a new model.

In the list of parts, you forgot the VVT badge. BTW in the cost mentioned for replacing the roof, did you account for the headliner trim inside? This must have been cut when the sunroof was installed.

He must be contemplating it for the kick of doing it. I don't assume that he is not aware of the risk he is taking.

As per whatever little I know, you will need to modify the wiring to accomodate some sort of solenoid to activate the VVT at a prticular RPM according to the stock map.Also I think you either need to remap your ECU or source the VVT ECU for the VVT to work properly.

Atleast in case of mitsubishi, the MIVEC activation is done in this way, there is a solenoid which does the activation part and hence the ECU pinout shows certain pins in the loom that are connected to this solenoid.

I Dont know much about Suzuki engines but are you sure the block and head are the same in both the engines ? Shouldnt the VVT one have a slightly different head ? Just wondering.

Okay cosmetics put aside (lower in priority), CAM SHAFT/VALVE related changes are listed here. Ignore above costs, as they are not functional to the vehicle.

DELTA for CAM SHAFT/VALVE

CHANGED:
1. CAM SHAFT INTAKE - 12710-54G11 to 12710-56KE0 (9000)
2. SEAL, OIL (5.5X11.5X9.3) - 09289M05012 to 12934M68K00 - unknown price

ADDED:
BEARING, UPPER - 12737-68GE1 - unknown price
BEARING, LOWER -12738-68GE1 - unknown price

DELETED:
NONE

ECU cost approx id 8,500

Will followup with more components that are crucial to upgrade.

* Regarding economics of upgrade, I might lose more than 3 lacs if I sell my car. I will scrap this project is difference is more than 1.5 lacs (which is highly unlikely - excluding cosmetics, not a priority). I'm taking a risk, but its all MGA parts and will be assembled professionally at a castrol service centre (who has prior experience in engine and head swaps). Regarding sun roof headliner trim price was not included. Thanks for headsup. That situation will only come if i decide to upgrade to other car sooner than expected :-)

Webasto specializes on sunroofs. I guess it will cost upwards of 40k.
Here is the linky: Webasto Sunroofs India, Car roofs Accessories, Company fitted sunroofs, webasto Motherson India

OT: Webasto sunroof was installed by Pratham Motors (Maruti Dealer) as a genuine MGA accessory. It costed me 42,000 (39k is the MRP and 3K is installation charges, done by webasto employees). They have sophisticated devices that does not chip the metal when being severed. I lost my centre lamp however

Hi there,
I own a SX4 vvt 6mos old , Yes the Pick up and ride quality is better than the older SX4 but just marginally.
I was just curious to know the intention behind such drastic modifications that you want to implement.
1. If it is to improve the Pick up and ride quality, its not worth the effort as the difference is only minimal, instead pack another engine like the 1.8l or the 2.0l ones available overseas on SX4, would be an interesting thread, or else, easier would be a new performance car .
2.Engine change would automatically call for few more obligatory changes to improve performance like ECU adjustments, Gear ratios etc etc, Just be careful you are not worse off
3.How would this affect your resale value....
I was just a little concerned about the total value - pros and cons of the whole stuff.
Any ways i would be still interested to know what we end up with.
Drive safe

Devsoftech, I'm not sure if the gains will be worth the effort & costs. Instead, you could spend the same money on a performance exhaust, air intake, head porting & polishing and potentially, a remap. That will definitely give you more noticeable performance gains.

The biggest advantage - I can pull in second gear in city traffic (driving at 10 kmph), marginal improvement in FE (by 2-3 kmpl) and don't have to downshift (Most of the times confused between 1st and 2nd) in city traffic/stop-and-go. Gear ratios are the same (Confirmed as per parts delta). Resale - I didn't think about it, it might not justify my expenses and I might be at loss. Sourcing 1.8 l CKD will be not so feasible. If I would have opted for 1.8, I'd rather want to explore sourcing a scrapped CIVIC engine :-) (that can be a separate thread) Btw, with VVT if supercharging / turbo is done, it will not kill the joy at lower RPMs - The primary issue that only a VVT can solve.
Entire objective of the upgrade is to make it a much better "driveable" car restricted to a budget of 1.5 lakhs. Turbo to stock also will not solve low RPM issue as torque is not crisp.

On a high level, mechanic has told to change:
1. Timing chain/belt -15k
2. Intake cam shaft - 9k
3. ECU ( I have always considered ECU has a mandatory change and accounted for its expenses) - 8.5k
4. Throttle body -2k
5. Cylinder Head - Head Assy, Guide valve (Most expensive piece) - 43k

My take:
5. Oil Pump (new BS 4 and sync with updated ECU) - 18k
6. MAF sensor (sync with new ECU) - 2k

I'm very much confident that I might be able to squeeze in the budget. It might be a well learnt lesson for me, but as far as possible, I will retain same engine part number

Skipping:
6. Exhaust components - Will do once cat-con dies.
