[crash_ndie]

is it worth sticking to the f13 or going up to a biger box?? any1 got a clue bout that graph is that any good???

[chimp007_uk]

What mods had you done to the engine to get that power from a 1.6 8v?!?

Torque and power cross in the correct place 5250rpm.

[crash_ndie]

erm everythink, hi lift cam port polished 3 angle ground valves arp bottom end pistons dubble spring valves lighten balanced oil pump, 45's throttel bodies thats just what i remember got full list at home. that ok then???

[chimp007_uk]

Thats cool lol sounds about right, as said best way t check a power and torque curve is correct, they should cross at 5250rpm :)

Have you blown the gearbox or something?

[Pistol Pete]

Fooking jesus..thats some good power from a 1600 8v. Whats wrong with the current box? Maybe go to an F15??

[crash_ndie]

blown a hole in me last f13 cr but this 1 seems to be holding out ok but last time went pod it spunn all the way up to 3rd an pulld **** times on 1/4 mile, just wondering if a diff box will help, id go with a quiff but aint got 1200 quid laying round just yet

[Pistol Pete]

I'm not that genned up, but would an F15 be stronger then? Gearing might be different also.

[crash_ndie]

they runn big block drive shafts dont they? its going to be a track day car to so dont want to much speed low end ither???

[Pistol Pete]

I *think* F15's come on GTE's/GSi's....so shafts shouldnt be a problem.

[chimp007_uk]

F13's on gte's probably gsi's and corsa's run f16 i believe.

F13cr will give the acceleration, and low top end 117mph ish

Thought about quife internals?

[crash_ndie]

like the sound off that then!!!

[mikey14sr]

F13cr's were fitted to both GTE's and GSi's.

F15's come from corsa 1.4+1.6 16v's, they're a little bit stronger than an F13 and the ratios are a little different.

F16's are big block box's (1.8 +2.0).

I am guessing that modding the diff cover by drilling & tapping a thread so a plug can be fitted to speed up changing the gearbox oil would be a good idea, then change the oil after every hard session, ie. pod, or track day.

this should help the boxes survive a lot longer.

I like that idea :)

I like that idea :)

sometimes old fashioned thinking is better...

[crash_ndie]

any ideas what the differance it will be top end and acceleration between the 2 box's ????

pics or GTFO...

45mm TB's on a fairly normal specced 1.6 8v.... somewhat overkill and pointless. Either someone fisted you for the build, or you are blagging :D


Those portable RR's are less than accurate so dont worry.

as for boxes, I'd say a decent condition F13CR with a 4.18 FD would be ideal for all round. Top end will be about 125mph on 15's wheels and a 7500ish rpm rev limit, and acceleration will be spot on.
