f13 on c20xe?

[AlanH]

i have recently came across a 20 8v powered nova in a local breakers, it is running an f13 gearbox, i'm told these gearboxes run standard nova driveshafts, is this correct? and if so will it fit onto my c20xe? i'm planning on running my f16 close ratio box but i can have the f13 with shafts so would like to use it to get my car running until i come across a set of conversion shafts cheap. if anyone has any for sale pm me. the engine is not for sale but if anyone is planning to build one of these i could get the wiring harness and e.c.u. very cheap so pm me if ur interested, although it is far from the tidiest job i've ever seen, the ecu is just left dangling under the steering column. the car does run though so wiring works. can also get inlet, throttle body, a.f.m., head and all other ancillaries for a very good price.

F13 box is a pretty common Nova box found in SR's, GSi's & GTE's etc and yes they do use standard nova shafts/C.V's

As for wether it'll fit an XE, i honestly dont know, but ive got good money on it not fitting lol

[AlanH]

it doesn't look like a small block gearbox tho, and the f16 on my old 2.0 valver corsa originally came from a 2.0 8v so was thinking it would bolt on the same

[coombsey]

when i brought my redtop i had a f13 on they had redrilled a 8v fly wheel 6bolt and my xe has 8bolt you can have a xe fly wheel redilled to suit the f13 clutch so it will fit the box will get a pic up of the fly wheel the holes are aboy 20mm long by abou 12mm wide
it will fit if done properly i opted for the proper way f20

Anways, an f13 on an xe won't last long.... (13 denoting the maximum recommended power that it'll handle ie 130 bhp)

so if im using an F16 it isnt ideal when im running 170bhpish????
dont suppose 10 brake is worth ripping my engine apart is it?

Is that true? First time iv heard that. cool

[Stanley]

I seriously wouldnt **** about with a flywheel IMO.

I cant quite believe how much of the gearbox is missing :shock:

[John]

/\ Holy cow! I can't even imagine what would have happened if it had entered the cabin!

The ratings are used by vauxhall as a guide to the maximum power they'll handle that's all. I've seen an f20 on a 250bhp let last and last after mucho abuse, and i've also seen a tb'd xe running aprrox 190bhp kill many an f20. A lot depends on how good they are before being fitted i suppose, and how well they've been looked after.:)

[Mike]

Holy fcuking sh1t!! I have never ever in all my years of fecking with engines seen that happen!

[Stanley]

Its actually a notification of the amount of 'torques' (cant remember whether its lb/ft or NM) it can handle:wtf:. Not power...

i.e. 130 lb/ft

[John]

Sorry yes i stand corrected it's in nm iirc.

[Lee-170]

with a f13 on a valver you have to space the clutch out and re-drill the flywheel its fast but be warned my mates valver asta has gone through 3 f13 boxes in the last 4 weeks

[Adam]

You would have to be a f**king nutter to go diy drilling a flywheel!
Seriously, just take a look at those pics, thats the best case scenario, the worst being the flywheel shoots off in the other direction and swiftly removes someones head.



You can do f13 by swapping the fly/clutch, but i cant remember which fly you can use. But as said, the box will be stressed, and you'll have to run a small block clutch, so it'll be slipping in no time.

[R1CH]

Sure i've read somewhere you use somekind of TD flywheel (1.5 / 1.7 ??) not sure on the flywheel tho.
Can't see why you'd want to tho really, an extra ?150 or so on some shafts and you can fit a propper F20 box.
There was a local laddo to me had a F13 on his 16v Nova years ago, was quick off the mark but topped out about 120mph, think he got thru a few box's as well.

[Steve]

I went to see a 2.0 8v that was up for sale, that was also running an f13, bearing in mind that it was only a 130bhp engine.It seems to work but as others have said if its only temporary is it worth messing about with?

If you have to use the car straight away then it might be worth doing, but otherwise wait till you can run it properly on an f16 or f20.

[AlanH]

wow!! those pics have made my mind up for me! and 120mph kinda defeats the object of running a c20, think i'll leave the 1.3sr in for a li'l while till i buy some shafts and run my f16, dont like the idea of the flywheel destroying all my bodywork, or me for that matter. thanks for the advice guys.

[General Baxter]

bollox to using a 1.7td fly, its bloody massive and i could hardly pick it up lol

alltho i jammed just over 400LB through a std F13 WR, std gm clutch, lasted about 4 days lol

[Paul]

The last two numbers denotes torque not power.

[saloonwoody]

Modify The Pressure Plate And The Inside Of The Bellhousin , Iv Done This Many Times On Big Blocks And Never Had A Problem With It :)

Oh Yea Your Gonna Need A Grinder ;)

[Philsutton]

Cant understand why people pikey on a F13, for the sake of some shafts. A flywheel that weighs 6kg or more spinning at 6000 rpm has a stupid amount of energy, the old mini's are the best for it when people skim them with a grinder only for it to go through the roof.

[Stuart]

FFS AGAIN I'll explain the F numbers lol.


early boxes were allegedly rated in NM/10 eg F10 takes 100NM of torque (on a continuous basis, but not sure how long for)

BUT its now just used as a number to id the boxes.

Its worth noting that the F10 and F13 contain the SAME internals (bar gear ratios of course), meaning the "torque" rating that the F number may represent is utter crap..

agreed with Phil though, why be a total gypo and think you are saving money and effort, when you can EASILY fit an F16/20 box which is intended to be used with the 20XE

[General Baxter]

Oh Yea Your Gonna Need A Grinder ;)


?50 per lightened fly wheel, no warranty's included lol

[James P]

if your guna do a job well then do it propely. u can get cv that fit on nova shafts now for ?60 each. just do that and keep the f20 gb

?60 each :eek: where are you buyin those from!!!!!

[AlanH]

found a set of 1.6 16v tigra shafts for ?50 quid, just need mk2 cav inner cv's i believe then i can use my f16 box

What on?
They wont fit a nova.

[AlanH]

yeah bit of a sh*tter, thought they did. now need a set of 22 spline nova shafts if anyone has any for sale? knocked things back a bit, was gonna start puttin the engine in once i'd put the new rings/shells in it but pointless with no shafts

[Adam]

Goodluck!
Rare as fook.

And when they do come for sale there mega expensive lol

Could buy some "proper" conversion shafts/hubs instead.

[James P]

nova gte shafts aint that rare. phone up some vauxhall breakers. scrappies etc

[James P]

oh yer and you get the 22 spline hubs from chris ashley. have a look. v

why buy over priced gsi/gte shafts when cheapo TD ones are the same lol

[James P]

dout there different in price.

[AlanH]

150 quid for used shafts is a bit steep tbh, been offered a set for ?100 so think i'll go with that if i cant get a set of td/gsi etc. ones

[Philsutton]

what idiot sells them as TD when they are the same as GTE anyway regardless of whether they came out of a TD lol

[craig green]

I'd go with the F20 tbh.

I'd use an F13 on an 8v but not an XE. The temptation to rip the tyres up at 7k rpm is too much for a lesser box IMO.

honesty is the best policy lol

[AlanH]

yeah i no, luckily thanks to waterboy i hav a set of gsi ones comin on saturday
