hiya, there saturday yea in the on/off drizzle.. i like those wheels.. nice. BAM motor is 260bhp region yea from the usual remaps.
The wheels are gonna be for sale when i get back from hols. Also thr Miltek catback, heated leather seats, brakes, probably gearbox prop, diff and rear sponion too. Inbox me if youre interested......
OK, i've done some work on the ratios........and i'm working on the following parameters;- Gear change 6000rpm, 185/50/15 tyres. My comparisons are;- 1) ERF 6-speed 02M from Mk4 golf PD130 TDi 2) GVZ 5-speed 02R from Ibiza 1,8T 150hp 3) AUG 5-speed 020 from stock 8v GTi Golf (for comparison) 4) CDA 5-speed 02A from Mk3 16V GTi Golf I'm going to be powering with BAM 20Vt with say 260bhp (generic remap). Red-line gear road speeds are (1/2/3/4/5/6);- 1)ERF 32.6 58.9 92.8 125.8 156.0(!) 186.9 (!!) 2)GZV 33.0 56.1 80.2 105.5 133.7 N/A 3)AUG 31.4 55.9 75.3 95.9 121.8 N/A - STOCK 8V GTi 4)CDA 32.7 55.5 82.6 104.9 129.0 N/A I realise when thrust = drag, the car ceases to accelerate. The GZV seems to be similar to the CDA but gets longer legs in 3/4/5. The car is for road use essentially and a weekend toy although if I decide to do a 100mile trip i'd prefer to do it at sensible revs on the motorway. Where do I go from here to help me decide folks? MTIA
Not sure where you got the speeds from but i make the cda/dpa box CDA 33 56 83 105 129 on the gearboxman calc with your tyre size. I reckon as a start this will do and you could maybe add a longer 5th to lower cruising revs.
Sorry.......got the last two 'boxes in the wrong order.......my CDA figures are same as yours guv'. [now corrected] tshirt........doesn't the GZV box do just what you said? (although only by around 5mph at top end?)
CDA is about the shortest box you will need on a mk2 20v,i've spent some time in one with a k03s (stage 2 map) and it works very well but has a slightly high 5th as people expect,alot of other boxes use the same ratio's as the CDA but have a 3.3 FD (ala mk4 golf & ibiza) and some of the mk3 TDI use them too with a 3.175 FD (or close enough as its too late tonight) So why not try the CDA figures with a 3.3 FD and see what happens???
Cheers Tommy. I've played with the figures and yes a 3.3FD will lower all the ratios across the CDA box and give higher range for all gears. Thing is.......ideally I dont want to split a box and faff about with FD gears....I presume these are behind the end cap (was going to do this mod on my T4 van). What about that ERF 'box?? (the Mk4 Golf TDi'er) CDA with 3.3FD........36.5 62.0 92.2 117.1 144.0 N/A ERF 6-speed.............32.6 58.9 92.8 125.8 156.0 186.9 The ERF would be rapid off the line.....and then get longer legs in 3rd/4th /5th.......with 6th being purely for motorway cruising? (2250 RPM in 6th = 70mph)
The Shorter ratio's in the ERF doesn't mean it will be rapid off the line as you will probably just be spinning the wheels. In my car the CDA spins the wheels easily in the lower gears so a 3.4FD would be my best choice, as i'm adding an LSD. Although if you just want to get a box with this combo, you can get one from an Ibiza code EDT. Basically a VR6 box that fits on a 4 cylinder. Hard to come by though.
Hmm.....the EDT;- "Code 02J-EDT is Ibiza,cordoba, Cordoba vario 1999> 1.8l 20v-115Kw" Ratios 1/2/3/4/5/FD 3.300 / 1.944 / 1.308 / 1.029 /0.837 / FD 3.389 In gear change at 6000:- 35.6 60.4 89.7 114.1 140.2..........Not shabby at all. Is the EWP 'box the same as the EDT for ratios?? OK, so what about this GLB 6-speed (02s) from circa 2003/4 Golf and A3 FSi 2.0 's? Too big / weighty / RARE ??
Mine's an EWP box and i understand they are the same,as said above though,1st gear is redundant 2nd will not be much better (unless your on track with stickys & a diff) its more about 3rd 4th & 5th. I say this as you say its for a BAM (remapped i'm assuming too) Do you want it for the track or just road? 02S is very expensive and not worth the bother IMHO
Cheers for the feedback. The car is for the road.......weekend blitzes but also for tramming up the motorway the odd time. Don't want to sit at 5000 rpm in top gear at 80mph! Yes, 225 BAM which has already been mapped to probably 260bhp as a guess. Right.......cutting to the chase......the 02R gearbox I mentioned is already here. Is it usable?
BAM lump now extracated from its crippled donor. 02Q geabox looking rather sad for itself......bell housing busted around starter motor aperture, and propshaft drive totally solid! The tranny might be good for someone doing synchro to Haldex conversion, seeing as this one's only done 64k.
Still ultra-undecided.......... > I have an 02R JDB gearbox 5-speed sitting in the garage. Low miles. > Won't find an EDT 'box at sensible money > Have found 6-speed 02M ERR 'box for good money. Originally Leon Cupra 1.8T (ratios are a tiny bit shorter 1st / 2nd but otherwise look ok) > Is a Mk3 16v / Corrado 16v box gonna be too short? Have seen loads of different 'boxes used and on this basis I guess there isn't a "right" answer to the question!?
My 02A is great through the gears, but far too high on the revs for motorway cruising any distance (although great for being on boost straight away to boot it without dropping to 4th )
