to the point where he reverted back to a standard T5

abdr500

iTrader: (1)

realy why what troble did he get could it not be 1 off

JonnyBravo

Its been rebuilt more than once iirc

Constant hassle and as Rich said he is now back using a stock T5.

Bernie is rebuilding it again but that doesn't mean it will last any longer than it did last time.

yea but can some one make it clear what went worung with the box as i am that close to buying one ..ok if not this box what else can i use i know marco is doing one but it never seems to be ready or finished lol

Dan

Not sure if it was the power of Dingy's car that broke the box?

My mate has one in his Saph, Straight cut First gear and semi-straight cut 2nd & 3rd or something IIRC, works perfectly and has been a fit and forget item!

He isn't running 500+bhp though, more like 380ish

JonnyBravo

Tremec box seems a good choice tbh.

If its a big power engine then the Quaife isn't for you from what I've heard.

I don't think Marco has a properly sorted T5 just yet.

Dan

I want this Sequential Mullett T5 to hurry up!

tko thers to much hassel to fit one just want a direct fit realy 500 bhp is all i got wount be going any more

any idea when they will be out

JonnyBravo

I'm sticking with a stock T5 and a 3.9:1 cwp, ideal setup for trackdays and a T5 will take 400hp all day long, using nitrous will be what will kill mine but hopefully as its simply for short amounts of time it will hold together

A mate of mine had to run one in a race car for a bit and he said it was fine until you really start revving the engine hard 8k etc..

The Quaife is only rated to about 420hp iirc although they obviously say that to cover there arse.

All the options are on that thread Dingy started a while back but tbh nothing was cheap and I couldn't justify spending 4k + on a box that IF it goes wrong is going to cost a fair anount to sort.

JonnyBravo

I'd say the hassle of fitting it will still cost you a lot less than a proper allegedly good box.

PM Ryan as he was going to use one in his old 3 door

i more intrested in the mullet Sequential box any one now how much and when it will be ready

JonnyBravo

Bit of a price jump from a Quaife to a sequenital mullet

I bet you wont get any change out of 5k for one, I have no doubt it will be a superb bit of kit though

Sequential boxes are for track or race cars only, why on earth you would ever want one in a road car is beyond me

Ryan

TKO isnt much hassle at all really, few custom bits but the cost isnt much more that a cut t5, and much much much better.

Custom Prop (Easy)
Custom Bellhousing (Think Reyland do these)
Custom Mount.

Cost all in i would guess to be 2.5k inlucinding the box, and as we know that will handle 1000bhp near enough.

ok surley ther is a good gearbox to go in the 2wd cosworth as a direct fit weather it be a gearset or a made up kit or is it just a few of us that keep braking gearbox

Dan

Nope, not at the mo, Marco hasn't really given any clear indication of plans or cost yet.

PM Marco though, he will give you some shithot advice on all things transmission!

does it have a speedo drive and how heavey is it comperd to a t5

Dan

Oh fookin really Ryan!!!! 2.5k all in!? You sure!?

Martin-Hadland

iTrader: (2)

I can do a direct bolt in TKO kit if needed I have TKO's in stock.

Ryan

yes dan, i even had a company lined up to do it

Didnt need a speedo drive as i was running a Stack Dash, but pretty sure they can come with speedo drives, just an optional extra that is blank off on the off the shelf TKO600's

Dan

... and price on box alone mate?

Ryan

think there about Ł1500-1600

Dan

Not bad considering gearboxman charges Ł1400 I think then!

I take it they are a standard H-Pattern g'box?

Ryan

good god you ask a lot of questions.

yes H pattern.

lamb chops

hehe at Dan Dan the question man

Cossiebros

I have the gearboxman T5 in my car. Didn't have any troubles with it with 400bhp.
My brother took it to the ring last year and he said that on the end of the lap, the 4 to 3 gear change didn't go so smooth anymore. But after a few minutes was fine again, so maybe it is caused by heat problems?

We'll see how well it goes with my new 550bhp (hopefully) new engine, which is almost ready

rapidcossie

The box in my car seems to be standing up well....not done many miles really tho.

Will get a proper test this year.

dumped

The other good thing with TKO is you are getting something with mass produced tolerances etc It should definately do as says on the box, not like a small production run aftermarket product that may do what it says on the box imo.

Dingy

My bernie box has been plagued with issues from day one.

They have found a problem with it and its been fixed....

I had the uprated forks etc to...

re-fitting at the weekend with some different oil from millers - quaife recommended....so lets see....

Heat on mine made no difference to the problems....cold hot was exactly the same.


Martin - does the tko kit come with a new bell housing ?

iTrader: (1)

Must admit my box from Gearbox man has been spot on, was a big tooth kit with bronze selector forks, think there about Ł1500 off him, i ddnt pay anywhere near that though

Dingy

Oh an my car is 380bhp on dyno dynamics rollers or 450 or 420 which ever random bs figure you want....

Made 380 on nobles with the t34, then 486 and now 560 at full chat - i know which i believe LOL

Martin-Hadland

iTrader: (2)

Modified T5 on an exchange basis.

Linsay

Dingy, your main problem with the box was it would not go in gear at high revs wasn't it - hope it's sorted, having driven it with both in

Dingy

Yes once your past 5200rpm it doesn;t change gear LOL or didn't...

Will see what the new box is like

abdr500

iTrader: (1)

tko seams to be the one but what about clutch does that need changing how about a good used tko box any for sale

Martin-Hadland

iTrader: (2)

No point in me spending the time to pm a quote for new then!!!

abdr500

iTrader: (1)

yes do a new one as 99.9 % the cost of new will be close to a second hand one and i no what i would rather so please go ahead with new just a estimate price on box and parts to fit and forget

Ryan

cant think of a time i've ever ever seen a TKO 600 for sale second hand

There just not sold second hand, as they dont break
