Any experience on 20v on throttle bodies?

Does anyone here have a car running a normally aspirated 20v 1.8 4cylinder engine running on throttle bodies? Any information or contacts would be appreciated.

Thanks

 

Mad20V on here has a 2L 20V on throttle bodies - only one I know

Cheers

Rob

 

Speak to Matt or ChrisP @ Designa Dubs, Chris was going to put Throttle Bodies on 1 of his jettas that had a 20v

 

How dare you spread such rumour......
I WAS going to be doing it, problem is I scrapped the car, but have still got the engine mind, tho what the hell I'm going to do with it?

 

nice sig btw!

erm... I'm the guy Matt's talking to about swapping it...

(although judging by that autosignature of yours I'm having second thoughts... )

 

Out of interest how do you get a 2.0 20v engine? From memory VW never produced a 20v 2.0 ?

 

Ah, so thats you!

They did produce a 2L version of the engine, speak to matt some more, he'll tell you the details, of what are the pick of the bits

Ignore the sig, I was under the influence of a touch of booze, and a bet that I wouldnt do it

 

the 2.0 litre engine is an n/a unit and all alloy - engine code ALT

tt

 

I just knew you'd remember the engine code (that I couldnt)

 

only cos i've got one sat in the corner of the workshop back home

tt

 

I'm reliably informed that these ALT engines are quite hard to get hold of and a tad expensive [:^(]

Chris, as soon as I hear back from the MSA scrutineers as to whether I'm allowed to use your engine on tb's in my class I'll let you know.

Quite looking forward to the noise the engine will make

yes they are hard to get hold of but mine was less expensive than many 20V turbo engines

tt

 

Just heard from the scrutineer, I'm allowed to use a 20v normally aspirated engine on tb's in my class as long as it's a VW one.

 

excellent news

loverly noise

 

Better check the regs for having to use a block of same material as std -
2L 20V is an ali block and as such would not be allowed unless your car
was fitted with a std ali block, which it wasnot.

I run in class 3b, mod prod upto 2L, and regs are pretty free

free gearbox
free cyl head
free intake and exhaust
free engine internals

but what is stated is that the block must be of original type fitted by the
manufacturer (or a derivative thereof) but must be of same material as
original

Change the block and you go into sports libra......and will loose.

Rob - Granted the 2.0 is an alloy block, but the 1.8 20v isn't an alloy block I'm reliably informed, which is the one I'm planning to swap with ChrisP. (I'll stick with the 1.8 for this year and bore it out next season if I feel adventurous) Interestingly the rules have been changed recently regarding engines in the class 10 Category D - Modified Production Sports from 1400 to 2000;

rule 12.5.1
'The engine block must be externally identifiable as that fitted to the original model or specified option and it must remain in the same capacity class as the original car or the manufacturer's specified option for the model and engine. Modification to all components is permitted'.

12.5.2
'With the exception of any engine fitted to a vehicle complying with 12.1.2, it must be of a make and type produced in at least 5,000 identical units and fitted to a vehicle originally available through the normal commercial channels of a vehicle manufacturer'.

I had this explained to me by a scrutineer, basically the rules mean that you can put any engine from the same manufacturer into your car as long as it stays in the same 1400 - 2000cc capacity.
If I were to fit a Vauxhaul twin cam to the car, even if it was under 2000cc that would move me to Sports libre. But if I was to move to a 2000 twin cam that came from a VW that would be OK.
Apparently this way people with Midgets run K-series engines, and Escorts can run Zetecs etc. in the Modified class.

 

Hi

I run in mod prod myself so are very familiar with these regs. 12.5.1 and 2 have been pretty much like this for the past few years as far as I recall. You are right that the 1.8 20V is an iron block - I would not advise going over 83mm bore with it though so to get your 2L you will need to stroke it as well. I, and the scrutineers where I race, would not agree with the statement that you can put any engine of same capacity class from the same manufacturer into your car - it has to be externally identifiable as the same line of engine - abf is passable as kr or 9A I would say (and a common example up here is NA cossie yb in Mk1/2 escorts, passable as the cossie block is a derivative of the pinto that was originally fitted) - Of course this is just for mod prod - road modified you have to keep the original engine but it can be modified and std is original engine std.

Personally, I think its a bit thin saying that a K-series is a derivative of an A-series and think the Midget example is taking the urine - and should be sports libra

Cheers

Rob,

Hi, I also was bemused by the Midget's running K series in the sprint series, as you're right it's a far cry from the A series engine, but I'm reliably informed they do run them.
Anyway I plan to stick with the 1.8 20V as it is easily identifiable as a derivative of the original block. The only thing I'm not certain of is what sort of power I'll get from it, Matt thinks around 185 or so, but I'm yet to speak to someone who's had it measured...

Carl.

PS
According to Matt at DD you combine a Mk3 crank to bore & stroke the engine to 2.0 - anyway that's for future tinkering

Rallye - nice manifold, but no description...?
