JTL · Post by **JTL** » Fri May 20, 2016 2:55 pm

Hi guys Im new here

Just need some advice Im running Carb with a 1.8 block and 2.0L 8v head.
Wanna know if what must i do if i wanna fit a supercharger with 36 dcd carb?

My motor was done recently by myself and runs great. I have increased the bore size.

What i would like to know is :
Do i need to port my head?
Do i need to put a stronger gasket on?
What pulleys do i need?

Will be a waste of time with a carb

drop compression ratio for a start. port head not needed to be able to run it.
pulleys will depend on the charger. no way we can just tell you like that with NO info.
suck through carb setup with charger. yeah really not ideal.

Okay so how much do you guys think it would cost to fit mp9 with management?

I'm already running EFI head?
Must I upgrade My tank?
And what will my end cost be like with tuning and everything?

Honestly you are not supplying enough info for any of the answers you expect back.
But as i said the otehr day R60k to 80k for a properly executed turbo conversion and it will be roughly the same for supercharging.

No i do not have the fuel rail and stuff yet.
And i have a make2 jetta clx

With 1.8 block and 2l ady head
I can get a complete mp9 intake for R1200 and mp9 loom for R400

What i want to know is what else do i need?
What must I do with my original tank replace it, Or can I just fit an inline Electronic Petrol pump?
And how much can i get a management for?
And do i need a three pin coil?
Or will my original coil work? (I have the bottle type coil)
Do i replace my dizzy?

Yes it will but not by much. You will need a new non vacuum distributor. Management will set you back another R4k, gaskets and engineering for the new head will come to the price of a import 2L engine. You will get way more power with a 2L then you would with the 1.8. Much more torque aswell. What is the condition like of your 1.8?

Ok then go for it. Should pick up a few kw's and improve driveability. Fuel injection is better in every way.

Good morning guys, my apologies for jacking this post, Im new to this forum and my question is quite the opposite. I have a Mk2 jumbo, HM block 1600 head (head has been ported and flowed). I would like to change the sub to 2l but keep the head, is this possible or MUST i get a 2l head?
Thanks

Will work fine, get the 2ltr head gasket set, exhaust may need more clearance if it's a long block, rather upgrade the exhaust system so the 2ltr can breath better if so
