hi all
was just wondering the best way to get a good top end out of the c1j?
my mates tungy seems to top out about 120 and he was awfully disheartened when yesterday a metro went past himthe metro has got one of them vvc engines in though to be fair..
it seems the engine has more to give so my guess is gearbox? do you think the clio 1.8 16v box would give a better top end?
thanks in advance.

jb3 out of the 16 valver or clio / diesel gearbox that will give you really long gearing , or jc5 from megane /laguna/ 172 but you will need to check how compatible they are with the gtt speedo cable
whats the difference between the jb3 and the standard gt box gearing wise?? how much top end would you gain as im sick of sitting at 60mph at about 3k. (dont like doing long distance revving that much).
GT's are not about top end.if you havent beat it by 80mph odds on your not going to.
jamie, is your mate the dude who brought the bits off me.. If so tell him to drop by, im sure hes only running about 10 psi, we will spend some time on his car and show him what the gtt's really about, or failing that he can come for a blast out in mine..
I had a play with a lad called paceys metro vvc.
I got a Clio 16v ox in the campus at the moment, these are shorter ratio then the standard 5 JB3 box, i get less mph per revs so my engine is reving more at 70mph then it would with a standard gt box in.
If your after top speed then its prob not the way to go, to be honest if the car is capable of reving abit higher than standard it will do more than 120mph on the standard box.
The 172's JC5 is also shorter. The standard GTT's JB3 is about as tall as it gets as far as I know.
yes true,but im not only thinking of top end im thinking of a lower rpm when cruising at either 60 or 70 mph not to mention mpg, atm with 195/50/15's at 60mph my rpm is 3k and at 70mph around 3.5k, just sounds very revvy when you on the motorway and cant be good for wear and tear on the rings ect, also ive found when sitting at 60 mph my engine is deciding whether to boost or not so it jerks as its trying to boost but not if you know what i mean, so by using a longer ratio would hopefully cure the jerking as id be sitting well below boost at 60mph.Originally Posted by Adam 005
My tungy done 130mph on the datron timing gear at brunters on the 2 mile straight, standard engine 1bar boost (144bhp fly).
Ive no idea what spec your mates car is but it must be low on powerHeavily tuned gtt's pull pretty well at top end, i imagine the van is good for a gen 140 although i have never tried
are you going by speedo or satnav as my speedo is way out when doing 70 on speedo its nearer 100
my 5 is good for 130mph at 5800ish rpm with R11T box fitted running only a bar of boost
Mine was on the datron timing gear which i believe uses gps? done it three times back to back in the tungy no probsare you going by speedo or satnav as my speedo is way out when doing 70 on speedo its nearer 100
Jays raider done 130 on satnav for about 6 mile on the autobahns, engine at a similar state of tune. Gtt's blowing up at high speeds pah its a myth

on a standard box and 16" wheels I got a gps 138mph at 7000rpm
on the r11 box it does a gps 128 at 7000rpm
neither of which I'd ever do again, they are too unstable at high speed
Mines ive had to 120mph on the clocks ....mines running 10psi ..no idea what box im running ...the previous box ive had 130mph on and it was still climbing through the revs(ive no idea what gearbox that was lol)
For top speed jamie ud be best going for a diesel box from a clio 1.9d ...as said tho you will need more than standard boost to get there tho
so would that be the jb1 gearbox bassj?? whats other peoples opinions on this box??
Punch it Chewie...

Was that on axel stands
right, done a lil research,
clio 1.9 d box final drive-3.29 top gear ratio-0.80
r5 gt std box final drive-3.73 top gear ratio-0.76
any boffins out there can you work any sums out with these such as differences at 60mph??
he's running around 15psi now and clattered the mighty metro upto 100mph.. it just didnt want to go past about 125 ish.. like i said the engine felt it had loads more to give..

i would be veryif i got over taken by a metro no matter what engine it has in it
i would be very
agreed!
Taken from the comments:
'.....and has had alot of money spent on it!'
He obviously doesn't know the owner
Who's car was this then?
whats the point in racing. the 5 gtt is about 0 to 100mph and how fast it gets there. leve it to the pod and track days and save your car licence.
it was at a private strip
thats ok then. but like i said the 5gtt was built as a fast sprint car. not a top end car. if you havent beat the car by 80mph then you wont beat it mate. simple as that.it was at a private strip
the 5 killed it round our local sprint course also... hmm...
hopefully it will have abit more top end when its cammed?
thats good mate my 5 running 26psi and its so fast up to 110mph but it top end is only 128mph for that much psi you would think it would have a big top end but its not the case.
yeah... like you say... the 5's all about getting you there quick lol.. 26psi
Whats rev's was he taking the engine too?he's running around 15psi now and clattered the mighty metro upto 100mph.. it just didnt want to go past about 125 ish.. like i said the engine felt it had loads more to give..
i couldnt tell you to be honest. i will ask him when i see him next.
With 22lb of boost i can get my van off the clock quite easily, approx 140 on gps (flat out on track). Its all about selection of parts and setup, loads of boost doesnt necessarily mean a lot? ..
thats the game...if theres grass on the pitch lets play!!!
after watching this link i found another vid of a r5 but this 1 is a r5 beating a ferrari

seen that before,is it an mr2 though
thats the real deal is that.seen that before,is it an mr2 though
the vvc metros are a force to be reckoned with
I've seen 136mph from one of my 5's . I was in the slip of a vw golf gti at the time going down hill. I was doing 6700rpm i recon on a standard box and the heat sheild got that hot i had to spray water on it to stop it smoking!! ( private road )
well my 5 will be ready in the new year with a few tricks under the bonnet and im going to the rolling road day that blunty is organising in cheshire. so its make or brake for the old girl.
but as a few have said its mainly about the 0-100......
all about the element of surprise....
gta love the 5's!!
There's a metro round my way striped out with a 1.6 16v k series under the bonnet.a total wepon
There's a metro round my way striped out with a 1.6 16v k series under the bonnet.a total wepon
BUT........its still a metro
Never had a speedo working or working well enough to see how fast i was going. lol
Maybe im only doing 40 and the 5 just makes it feel fast?
BUT........its still a metro
id get a closer ratio box in there, legally u can only do 70mph anyway
my bros r5 (markeyturbo) used to out accelerate my old corsa (2.0 16v throttle bodies 250bhp) to 100-110 but after that the corsa would leave him for dust lol
As I know you only have to change the 5th gear (from a Clio 1.8 16V) to get higher top end and lower rev @60.
dare i say it, but you have a lack of power. my gtt on standard gearbox would go off the clock no problem....
I was gonna say something similar as i have seen J's car go off the clock on 15-18psi, 0-100 is pathetic, you can do this in most cars.
It shouldn't be a problem for anybody with a GTT engine and gearbox to get into the 125mph + area. I am not saying it's stable or legal at that speed, but it is easily done.
after years of sports bikes ,cossies and an r32 that gose to the limiter no probs
i can honestly say the 5 in three figures scares the **** out of me
the speedo drops to zero after about 90mph so no idea how fast its gone
but its fast enought for the rear spoiler to fall off
180 on the gsxr no probs 100 in the 5 feels faster than the bike
Every gtt i have driven at good speeds has never felt unstable or scary, unless its a total sh*tbox with knackered suspension or steering its fine
