In the process of installing an Ed30 2.0T FSI lump into my Lotus Elise 111R.
The intention was to keep things sensible and go for 300 bhp Stage 1 level of tune. Now though we are adding a ProAlloy chargecooler and therefore it would be silly not to up that to 350 bhp.
Someone on here very kindly suggested we upgrade the diverter valve to a revision d unit which I have done :happy2:. I am now looking at fuel pump options and from what I can see the two best options are:
- APR pump which replaces the entire unit from what I can see but costs £750 :surprised:
- Autotech pump which simply replaces the internals and costs a more reasonable £359
Which should I go for?
And what else should I be looking to upgrade on this engine?
Thanks very much in advance- any advice massively appreciated :drinking:
-
i hava the autotech upgrade and its running fine for one year and 15.000+ km ,didnt try the apr pump so cant judge is it better ,but you cant go wrong with autotech
-
Thanks for this :happy2:
What kind of power are you running?
-
I was runing 344 with OEM pump ,now runing 357 with autotech pump and RS4 valve ,need to get it remaped for the pump ,so I presume it will be around 360+
-
Thanks Dario :happy2:
Would anyone have the part number for an RS4 valve? Is that something that should be replaced as well then?

The part number is 079 130 757 mate and should cost around £35 from your local audi dealer. Its not an essential item and is really only worthwhile if running Stage 2+ software. Basically it just helps maintain fuel pressure upwards of 130bar giving your injectors and fuel pumps a little more headroom. It may also help to lessen the dreaded 5200rpm flatspot that some people have experienced.
A 2.0Tfsi engined Elise eh? . . . . sounds like fun :grin:

Thanks very much for that- really helpful :happy2:
I am looking to go with the Autotech components for the fuel pump- just can't bring myself to spend that much on the APR one.
The car will be pretty special when finished. PSR Automotive in Bishops Stortford are doing the conversion for me and naturally we are keen to make sure we address any weak points now while the engine is on a stand. They are just fitting a proalloy chargecooler and radiator at the moment.
I will post a thread when the build is complete for anyone that is interested :driver:

Nice one bud..... i look forward to seeing it :happy2:

Once again thanks so much for the tips to date :happy2:
One other thought- at what stage are you guys upgrading your clutches? At Stage 2+ levels of tune, is it one of the components upgraded as a matter of course?
-
i run Helix SmF kit,chatters a bit ,but you live with it :D
-
Is there an alternative upgrade clutch that doesn't chatter?!
-
Not sure you would need a uprated clutch with the weight of your Elise, it being around half the weight. :wink:
Also if your charge cooled then, Revo 2+ software with SPS switch would be my preferred engine map.
Also inspect the cam follower regularly, they are mostly fine on UK engines but there is a few instances of them failing with big bills. And for the price of a replacement it's cheap to replace. :happy2:
Catch can maybe.
and you will need a LSD diff for sure
Also keep your eye on the oil level, a fair number of these engines drink more than George Best.
Apart from that the German over engineering means they are pretty much bullet proof. :pomppomp:
I cant imagine how ridiculously fast this car will be a 2+ Edition 30 is very fast already never mind losing half it's weight. :laugh:

Thanks Top Cat :happy2: Is that your Type 72 in the photo? Are you on Seloc?
I am making note of all the great advice from the is forum- can't tell you how useful it has been.
Just following some of your points-
Is there a specific catch can you can recommend? This one has been suggested:
http://dubtek.co.uk/index.php?main_page=product_info&cPath=22_32_33&products_id=477
The car won't have a LSD initially- I can see that I will have to be gentle on the throttle as I am guessing it won't be hard to break traction in the car once done! The garage doing the conversion have done a couple of other 2.0T FSI conversions in Elises so I will ask them how the others got on!
Is there anything that can be done now to minimise the risk of issues with the cam shaft follower? I am pretty sure I have seen some uprated components on the Forge website?
Obviously I don't want to buy parts that are not needed but if these little components can be fitted now and they don't cost too much, I am naturally keen to fit them.

The pcv revamp that you linked does not include a catch can as it merely fixes the weakness of the oem pcv. It has the same weakness as the oem pcv in terms of carbon and other gunge deposits on the inlet valves .
If you're after a catch can to minimise these deposits then bsh do one http://dubtek.co.uk/index.php?main_page=product_info&cPath=22_32_33&products_id=478 as well as Forge (more expensive) http://www.forgemotorsport.co.uk/content.asp?inc=product&cat=260305&product=FMMK5CTC . Both do the same job so it's up to you on how you want to spend your cash.

Thank you very much for this- How expensive are Forge components!! :happy2:

It's in the link I posted above, £338.34...

The cam follower can be changed easily when you uprate the pump they are only about £25 and its a 2 minute job to fit it. :happy2:

Nice one :happy2:
Which is the recommended uprated cam follower to go for??
Sorry- all these questions!
-
I dont think there is a actual revision, though they did start making them tougher about 5 years ago now. You just need to ask for a cam follower for the TFSI 2.oL engine. Any Audi or VW dealer will supply. It looks like a ickle thimble, the top part takes a battering, and in severe cases disintegrates sending metal around the head and sometimes throughout the engine.
If you look down this page there is a picture of one that has given up the ghost. The guy had to have an engine strip down and clean.

This is very rare though, lots of modified engines on here and no more than a handful that i can remember having catastrophic failure. Hundreds in the US though.
If you get it checked on each service you will be fine. :happy2:

hi
sorry to butt in , ive got a question....
whats the up side?
is it worth installing one these valves if your running a max'd out ko3 set up?
is there a down side?
are there any problem that it can cause?
a little input by some experience would be appreciated.....
thanks
:happy2:

Hello all, just a quick update (after all this time) to once again say thank you for all the great advice you have given me and that the car is now finished! It is being MOT'd tomorrow and put on a rolling road Wednesday when the SPS switch will be calibrated/added. I am looking forward to seeing what kind of power it is producing- I was taken out in it (on private roads) and first impressions are very good- my god it shifts!
Once I have the car back I will post up a more detailed write up with some photos. The 2.0T FSI is the perfect fit for the later Toyota engined Lotus Elises/Exiges with their larger engine bays. The catch can is hard to get to though (through the wheel arch) so I hope I don't need to empty that too often?!
