sorry to go off topic chip

martin do you still have the 20vt rover ? i cant believe that some of the zr owners aint doing that conversion instead of the t series turbo. iv noticed a couple of guys that have 20vt converted r5 gt turbos and tbh if i was going for 250-300bhp this is the way id like to go.

anyway back onto topic id defo look at the k04 turbo if your looking for 280-300bhp maybe can yield a bit more with the jabba manifold etc

Agreed, I want to be able to map it myself freely and I alreay have the aftermarket, I just cant see the point in the hassle of trying to get the immobiliser off etc when I can just whack it on an ecu I actually like mapping?

Plus I would quite like to use the ECU for a screen used as a dashboard which I can do readily with an aftermarket ECU, and not with the OE one.

Yes, I have two now... The original yellow ZR and I bought a customers ZS track car which I haven't had chance to try out yet.

brilliant mate , i actually here the zs is a more capable performer on a track not sure how true this is though

Martin, I assume you are on the rover gearbox are you?

If so, whats involved in fitting it to that engine, as its got a LSD so potentially a good box for me to use seeing as I have to have shafts made anyway?

Turbo Transit

Theres plenty available for the ME7.5.

Theres even tuners doing software that allows you to tweak and modify their maps yourself. (Eurodyne Maestro 7 is one that springs to mind)

Some tuners are also doing "MAFLess" tunes, which while i dont understand fully, seem to use the wideband lambda as the primary source of fuelling info?

Yes using a PG1 uprate box, I will get some pics up..





What happens if you don't fit rods..

Chip

Kevin, But what advantage do any of these standard ecu based setups off me over an aftermarket ecu I already have so costs me nothing but a few quid to make a loom and will map myself for free anyway?

Just to note all seat's fitted with this engine were on fixed term servicing so 10k or 12 months

Martin, that box fits up there nicely, I assume the equal length shaft bit is standard rover?

I know you arent a trader, so I will go and look on your website to see if I can find a price for the conversion parts to fit the vag engine upto the rover box, and i'll update the thread if I can find that info.

500 + a donation to the VATman sounds pretty reasonable in the grand scheme of things.

How much do the LSD boxes tend to go for martin?

They are quite a light box IIRC?

Gets me the two things I want most out of a box, the LSD and the Equal length shaft all in one fail swoop, and the change on the VAG boxes isnt great and from what I remember of those boxes they change quite nicely?


Whats your honest opinion of the PG1 box overall as one for a conversion like this Martin?

Cable clutch and rod change I take it?

Martin-Hadland

iTrader: (2)

LSD boxes go quite cheap, they are indeed light and because theyve been around forever there are loads of gear and diff ratios to be had.

Clutch actuation is by cable or hydraulic depending on the model the box comes out of but all the bits are interchangable.

There are basically 2 types of PG1 box... the std one that's fitted to the lesser powered cars 1.8 4 pots and the 'uprate' box which is fitted to turbo and V6 models... That's the one to go for.

Btw, turbo shown in those pics is a K04

pg1 is a really good box i had one fitted (lsd type) on my old 192 bhp n/a mg zr

Cable clutch would suit me TBH as that is what the pedal box in my car is for, but its nice to have the option to upgrade to hydraulic later on.

Sounds like the ideal box, and it looks like it will fit the space better than a VAG one will!


Whats the change like? I assume you are happy with it on Morris?

Actually, just realised the elises I have driven had those boxes didnt they? If so, it was a great change compared to most standard boxes

Martin-Hadland

Gear change is nice, Porkie even remarked how nice it was once

I started with a ZS180 V6 box as I had a new one sitting there (they have no lsd as std) , added a Quaife ATB , swapped the belhousing for a 4 pot one (straight bolt on), changed the final drive from 3.9 to 4.2 and fitted steel caged bearings and it hasn't missed a beat yet ... Which is amazing as about 5 people shared the car at Bedford last time out.

Chip

Well porkie is a hard man to impress with such things, so if its good for him its good for me.

Sounds like a good solid set of modifications to do to the box, have been having a read around and seen people doing similar with the elise's

Have certainly seen your car taking a beating and if Lee "I have utterly no mechanical sympathy" Manning couldnt break it then thats a good sign too.


Is that equal length shaft in your pictures a standard rover item?

I ve linked a spreadsheet that clubgti put together for the 1.8t engine variations,

Also it would be worth looking on Seatcupra.net as the have an excellent technical section I would definitely recommend looking at Badger5 sections on their

Yes, fitted to MG ZS 180 models.

smithy20vt, thats fucking superb, thanks mate!


Martin, nice one, thats a plus point versus any of the VAG boxes too it would appear as they dont seem to be available to suit those.

Chip

With regards to the engiens listed as VVT, what sort of VVT system is it? Im not really bothered about having VVT so can it be simply disabled to leave a fixed cam timing?

rs-tuner

iTrader: (1)

The later 2.0 t fsi engine has equal length shafts so do the diesels.
I don't know if they fit tho

Martin-Hadland

iTrader: (2)

It's an emissions thing Chip, left disconnected it's fine.

Martin-Hadland

iTrader: (2)

Not all Fsi's have equal length shafts... I have one here that doesn't.

smithy20vt

VVT on 20v's is for emissions use.... there is no performance advantage in having it as std (AFAIK) but..... it has been used on custom maps to improve spool time on larger turbo's (as seen on the monster 750 odd bhp lime green Mk2 Golf) and Custom Code do a 'VVT Attack' version of their software but I haven't seen any results of what effect that has as yet...

Sorry Chip Martin beat me to it

Here is JBS (Custom Code)s new VVT Attack map http://www.jbsautodesigns.co.uk/prod...vvt-attack-18t

Thats interesting, will have to find out if they fit, although TBH im quite sold on this rover box idea now, especially if its lighter like I suspect it is as weight that far forwards really does bother me (weight in the drivers seat im fine with though before some funny cunt says it )

Chip

iTrader: (3)

I will definately never want over 400bhp anyway TBH mate in this car, there would be no point at all, and I doubt I'll ever go past 300 realistically.

Interesting reading none the less though.

36kg for a PG1 box without oil in it apparently.


Anyone happen to know a reliable source for the weight of the vag boxes?


Engine weight for one of the AGU/BAM etc engines would be good too, including all ancilleries preferably if anyone can help?
