Title: Engine swap
Post by: Haribo! on 15 October 2010, 16:28
Well, I was thinking of changing my 8v engine for a mk3 2ltr job.

Volksmania have a wel running 2ltr 16v corrado.

Just to make sure I know I get the right bits, I only need the engine and downpipe yeh?  ive got a 16v back box already so i could get the middle sections if needed if its worth doing, if not can I still use my standard exhaust?

Can I use my current clutch and gearbox or do i need to faff about with that too?

Do i need anything else?  mines a 90 spec mk2 8v gti

C'mon bud, you've been round long enough to search on this.

The 020 rod shift is "made of cheese" - change it for a cable shift with cable clutch 02A
ABF's like to breathe, so the free-er flowing the exhaust, the better

Quote from: rubjonny
get the loom and ecu with it, run it on proper abf managmanet then dont need to change your fuel pump. zaust wise you can as above fit the 8v dp to the abf/kr manifold, but waht i would do is use an 2.0 8v or 16v MK3 downpipe and cat bypass pipe, then a std mk2 16v exhaust system will bolt straight up. the cat bypass will have the lambda probe hole in it as well

I search every time, but not everyone asks the same questions, and as a result, you dont always find the answers your looking for, in fact, I very rarely do. When I dont, I make a new post, its not a bad thing, just ads more info to the archive

I wasnt planning on changing the shifting system, I was gonna use my 8v box with my mk3 5th gear.

The info I was looking for is more like what else do i need, like drive shafts for instance?  apart from the actual engine, what do i need?  most of the people who have posted about this before have all seem to either have known these things already or have gone with different options, liek the different gear box for example. whereas im gonna need to know which clutch etc I need to use.

I do know how to search things, I just dont find it as useful as asking directly what it is I want to know, instead of what other peope wanted to know, youve been here long enough to notice that surely? :p

I didnt come across that one, the info i had found said i didnt need to change the loom. see this is why I like to clear thigns up

Saves alot of time and money.

You will need the loom / ecu also I would agree with Ben on the gearbox front.

ah see, now it sounds like too much hassle, if it was engine in, engine out, I might have done it.

I think I was just having a moment of speed greed anyway, I changed my 5th gear cog to save petrol, and then I go on about a bigger engine? madness.  I must grow up :p

Sorry to hi-jack but how do you change the 5th gear cog?

5th gear is usually the last cog on the casting so it can be done in house without gear box out I was pisssing about with the Rallye, wanting better ratios upto 5th gear and used a VR6.
You will need some gear pullers though.

020 box can just cope with standard abf power, any more and asking for trouble. also depends how you drive it, lots of wheelspinning from lights and slamin thru gears will kill it.  if you keep old box all the old shafts and gear setup will work, just change clutch for new MK2 8v sachs one and fit the old flywheel.

BTW Corrado engine is 9A which is k-jet based so will require a whole lot more faffing to swap, change fuel pump and lines etc.

to answer your original question, the 16v manifold will bolt onto your exhaust downpipe no bother.  however if you went 9a/abf using the oem management you would need a lambda fitting, when i do em i use mk3 downpipe and cat bypass as this has your lambda fitting in and fits straight on no clearance issues.  you will need a mk2 16v exhaust tho as cat bypass is larger bore than mk2 8v, or a reducer.  you may have to cut the cat bypass down dependin on make, miltek ones fit straight onto mk2.

abf is the way forward if you go 2.0 16v, better managment as std than 9A and newer engines too.

Is that because the old one blew up :laugh:

I'm not speaking from personal experience, just quoting the default replies on ABF swap's, DH being the author of the "cheese" one.

 :laugh: no it didn't blow up it's just all being transferred into another car due to terminal rot in the old one.

Yeah I know it's a default reply, just thought I'd offer the opinion that they can last ... how long I will soon find out :tongue:

020s are a bit pot luck, you see em blow up with far less power put thru and the odd one takes loads of power and holds up fine. g60s do liek to munch thru 020s but as i say it comes down to how you drive em as well.  know a chap with a g60 mk1 and hes forever goin thru them. touch wood mine has been going strong for the last 5 years, but it was a very low milaer 16v box from a town car so in great condition to start with.

if you plan to drive it round tracks on a regular basis or are danny_p then dont use an 020 box  :grin:
