Streetwise VVC conversion...IT'S DONE!!

Post  Captain Slow on 2/4/2012, 9:44 am

*Looking towards Matt Parker*

While I've got the head off the Streetwise, my thoughts have turned to a VVC conversion...exactly what is required? It's already MEMS3 (so presume it'd just need remapping to accept the VVC head), it's a 1.4 so I presume it'd need 1.6 or 1.8 pistons & liners? And obviously the (presumably MEMS3) VVC head.

Would the IB5 crumble under the increased power/torque?

Remove the 1.4 and fit the complete 1.8 VVC engine, you can stay with the IB5 box you will just need to retain the original flywheel and clutch which will be more than up to the job of the VVC, remember the chocolate box(R65) has always been the easy route for Metro and Mini 1.8 conversions and if looked after they will last for miles and miles (my first 1.8 was used with a 1.6 R65 which in the end was coping with 190bhp going through it and in total covered about 120k miles, only just started to get noisy) Smile
As its a Streetwise(25) you can use a 25 GTi or ZR160 engine loom and just plug the entire thing in, as the body connections are all the same, and of course just plug in the complete ECU and SCU with fobs if you get a 04 ecu set, or just the ECU and recode the ecu to your current setup(I can do this if you need)
Also you can bolt on the 25gti/ZR160 manifold and cat pipe straight upto the rest of the system without cutting and welding to suit the vehicle like on any other vehicle.

A really easy conversion to do basically and one that I haven't heard done yet Very Happy

btw, did you manage to sort out the fobsd/scu?

Yeah, sorted Matt-the contact in the fobs wasn't good enough, bending the "prongs" some more sorted it! Laughing

Dad has decided just to get the existing head overhauled Sad I WILL do that conversion when I buy it back eventually Very Happy it's pleasing to hear the IB5 will cope with it, that's a massive expense cut out if I don't have to buy a PG1 and linkage.

On a side note Matt-how much sideways movement is acceptable in the pistons? It's burning oil on startup so I'm suspecting valve stem seals (hence the head overhaul) but checking the pistons they seem to have a bit of movement. The bores look in good condition though.

So...the receipient of the VVC engine *may* have changed...

Anyone get my drift here?

Yeah, Dad has agreed to VVC the Streetwise. I'd lost a bit of interest in the 218is as the shell needs quite a lot of work. It'll make a more interesting end product too.

Matt-from what you say it looks like the BCU will need programming to the new (to the car) MEMS3 ECU for the VVC engine? I'm presuming the Streetwise's engine ECU won't run the VVC engine of course, or will it with a remap? (I was planning on getting the ECU remapped anyway once the conversion is done).

Tried replying last night but the site wasn't loading correctly Suspect anyway..

As your dropping the vvc into the streetwise you just need the engine loom from a25gti or zr160 so it lplugs straight into the car and then have the ECU re-programmed to the vehcile, which I can do in about 30 seconds Smile
The original ecu will run the engine fine, it will just be acting as a standard 1.8 mpi as you wont have any activation of the VVC actuators to alter the inlet cams duration making it operate as a solid cam large valve head which will be alittle be more pokey than the original but not quite as good as when the VVC is operating Smile
So if you like you can get it all working and then bring it to a meet and I can code the VVC ecu or pop over to me at some point and I'll do it, simples Smile

Happy days, I'll give you a shout when I'm done! I'll install it on the original Streetwise ECU to get it running.

Yes....my young padowan listened to me......a real street sleeper, mapped should be over 175bhp Cool Very Happy Very Happy

Well...it's done in the sense it's on the road...however Dad has now been bitten by the modifying bug and is requesting a short shifter! Laughing we've also got some 282mm brakes to source as the 262mm solid discs are already going blue Big eyes!

ITG is on order, hopefully arriving on Friday before the rolling road session on Sunday.

A few pictures...they're a bit pants as I'm not especially good at driving a camera.

Spec is so far:
1.8 VVC engine from a R25 GTI, A/C retained
PG1 gearbox, linkage & driveshafts with new Luk clutch
New radiator
Z&F tuning "Stage 2" remap
MG ZR160 springs/shocks

So am I, up until the point it does 120bhp... Laughing

Just noticed it's got a weepy diff oil seal (doh!), I must have caught it when installing the driveshaft. Nice Saturday morning job that will be then...
