Hallo, like some one know from another post here i am buliding a escort with s&j engine block 2.34litre, efr9180 and aiming att 800 maybe more.

ealier the car had 500whp and i used a t5 with quaife/gearboxman parts in, i was happy with that had no problem and seemed solid. but i gues with that more power i wil have now it will brake some time if i get good grip.

aso what alternativews is it for a trans that will do 800+++ other then tko600.

i also considering building the car back to 4x4 and then what options is it for that power and diffs etc to make it hold. not a milionere eather so that in considuration to

stevieturbo

What sort of usage ? what tyres ?

And as important...what sort of ratios do you need ?

And if you're talking about a 2wd gearbox first..and something you can then use with 4wd...you're really limiting your options and a TKO isnt going to lend itself in that direction without lots of custom fabrication work.

With such flexibility in mind, buy a Samsonas. They've adapted their "RWD" sequential gearbox for various applications both rwd and 4wd although the transfer box section is quite bulky.

Photo of it in an R33/34 type Skyline application in the foreground and in the background as a more generic rwd application.

But yes it is expensive, but it will give you the flexibility to chop and change at a later date. Tractive may offer something similar ?

Or for more conventional stuff there are many strong boxes available in the US although a lot of theirs feature a 1:1 top gear if that would be ok for you.
The video is a few years old but still very informative.


The photo is their own transfer case housing, they've also done it with Skyline parts, I thought I had a photo but cant find it

Caddyshack

one of the skyline box conversions might do the trick but it's gonna get expensive to have a skyline box built up for that power and adapt the bellhousing. I believe Reyland used to sell a newer style box, was it sequential? He had his own bellhousing and with the skyline box you can have full rear wheel drive and selectable and ecu controlled 4 wd, down side in 2 wd is you are still dragging around the whole 4x4 setup if you chose to fit it all ready.

stevieturbo

No factory R32/3/4 boxes were sequential.

Some guys used the OS Giken box for those conversions and all are 4wd and still required the Nissan transfer box at the back.

henning850

It is a road car rhat will be used everyday true summer and also on trackdays and so on. So road legal tires wheel be used. 18inch 225mm. Butt tginking about going up to 245 in the back.
I dont nees to have the option to shift from rwd to 4x4 it whould be cool hehe., i wil go for one of them, the plan was only rwd but now as things get alot more power and tork then i planed i am considering to convert back to 4x4 for better akselerasjon.
Iff 4x4 i wil gear wveryting down for fast acelarasjon and easy playing around. But the car should do 260km/t+ many long tracks to wmtry some gears in hehe.

I

If rwd and bomb proof is you goal then ask Rod what box he has. I don't think anyone has put as much torque on the road as he has in a yb powered car and his transmission has been fault less. He has a tko but not sure what type as there is a few

Caddyshack

That's right, Reyland did the os gicken kit, I think it was Ł10k back in the day for drive in drive out.

Caddyshack

With around 800bhp you will get immense wheel spin on 2wd, have you seen the videos of Rods doing speed runs? I would be 4wd for sure.

ajamesc

I was there that day mark got it wrong a few times and got it right a few times. When it was right it was still fooking fast even while leaving some black lines lol. I'm sure they don't suffer to bad on the road in gear

henning850

Thats my consern too, and now i only have the t5 with all quaife in it. So thinking cheaper sell that as new and buy a 4x4 trany and build it back to 4x4. But i gues there are alo to do with diffs to make them hold to ?

Havnt seen than, link to it ?

Caddyshack

I think most of my setup is good for 700bhp, I have the supra diff and cover in the rear on 6 degree beam, oppliger close ratio box (rated to over 700 bhp) though you prob wouldn't need the close ratios? And quaife front lsd. The weak point on mine being the 3.9 crown wheel and pinion up front, if that breaks then its Ł3,500 r n d diff.

The tyres will have come on a bit since Rods high speed runs with the Cardigan on.

Caddyshack

Here are some links...this is bruntingthorpe and it is quite a grippy runway

Caddyshack

"Beaten fair and square by a bloke in a cardigan"

henning850

Okwi, no i think i whould want the wide ratios on mine, then this is a kit he sel for the t5 and the mt75 or does him sel them complete. I think 4x4 is the way to go if i will se around 800 ponies
Alot of work to build on for supra diff ? And that front diff that dont crack 3 times a year is it posible ? It wil mostly go on the street and fast around tracks etc i am not that spining out tires inn 3minuts types and tap the clutch all the time.:P

Caddyshack

The oppliger kit is Mt75 4x4, you might be lucky as he is working on close ratio 6 speed and I expect that would still have Same top speed as standard.

Supra diff is not hard, I used a 6 degree beam from MK and the beam was adapted to take a supra diff with MK cover and MK bladed adjustable Anti Roll Bar. I have the weir spring kit. The front is the weak point so you may need to consider options such as r n d. Bara motorsport can help advise.

henning850

See what oppligger answear

But supr diff i will defintly go for, are they many difrent type and when to go foe ?

And to 4x4 even if you using 3times the money for 4x4 you stil praying to dont brake anything , and if you want somwtging crazy good that maybe will hold i think that wil be for next winter upgrade and drive rwd until then, but a good rwd ttansmision i will need i

Too crazy for road car ? Hehe :P think that 4x4 will be way to expwnsive now att the same time with the dnginw and so on. But the quaife with gearkit i have will break so need somwthing��

ajamesc

Tko your not break it you just need the right model number

ajamesc

I remember it I was there lol when it hooked it got some pretty impressive 0-100 times for rwd. I seen Rod say on here a few times out on the road on the move he doesn't really suffer from grip issues

stevieturbo

How many miles are on his ? of road or hard usage ?


If the guy is seriously considering 4wd, then the only sensible option is to go 4wd right from the outset.

To start with a 2wd box then try and adapt later...just seems silly. Although with the right 2wd box it would be sellable to recoup costs to go 4wd.

A lot of guys have put good power through standard R33 GTR boxes ? So on a budget that would be an option, or worst case buy a set of internals for the R33 box ?

value for money....simple old RWD box, a T56 Magnum is hard to beat though. I'd go for one of those long before any of the 5 speed TKO's

Even in the UK this seller seems to list them at a sensible price, but they're around $3k in the US. Being US made it should even be easy to get some sort of bellhousing adaptor to move to a T5 type fitment ? as these things are used on all sorts by everyone.

https://www.roadcraftuk.co.uk/index....product_id=734

ratios would also be a bit nicer than some of the TKO's and internals a much much better design, so the Magnum will shift much much better than any TKO.

stevieturbo

Samsonas Universal RWD box would be cheaper and I've no doubt also stronger.

Samsonas sequential a little more expensive ( depending whether Quaifes price includes or excludes VAT ) and Samsonas has a much much higher rating.

I think the Tractives might be a little cheaper ? And again a well proven and very strong 2wd option.

I'd be choosing either of the above long before Quaife.

henning850

no no not that crazy to build something rwd that i can converte later, thats crazy. i been just back and ford on 2wd or 4x4, but the more i read and cheeck i see that is no money for a solid 4x4 system this year, so then i keep it as a rwd as it is only need a bit stronger transmision.

har for norwegians with english and have the full meanings og thing corect telled ;P


Thanks, gone look them out

Caddyshack

There are quite a few different supra diffs, I went for the 3.9 from a non turbo supra. I think there are other ratios though. The other way is to spend Ł3000 or more on a ford 9 inch diff, those are proven in motorsport and do not break.

stevieturbo

9" would be overkill for that power.

Just buy and fit an 8.8" IRS although Supra is probably easier as people already do conversions

Mark V8

I think you and Caddyshack are talking about two different 9 inch diffs, the American live axle one and the Ford motorsport one that fits a near standard beam.

but back to Transmision, a box like this will hold the power, but the car wil go many miles to true summer do a trans like that need often repairs and overhauling etc ?

Paul_RS

iTrader: (4)

You'll want a proper diff rather than some Supra one. What I gather from talking to a few people is the Supra diff isn't really any better than a health 7.5" diff, plus it costs more to build by the time you buy all the add on kits needed for them to be fitted an not explode. If you are 2WD already I'd use your existing diff if it's in good condition.

Barra now does a front diff that is his take on the old R&D item.

As for sequential boxes a Quaife 6 speed one will be something like Ł10/11K plus VAT


That's what this car has with 500bhp.

If you go for 800bhp you'd need to talk to somebody like Rod, but I suspect you are into 9" motorsport diffs etc

ajamesc

You must be kidding if he has torque no 7.5 inch diff will last. A friend of mine broke 3 standard diffs then fitted a quaife that just lead to breaking the c.w.p.
He now runs a supra diff that has given no issues other that teething problems with the mount to the floor but that now seems to be fine. I had a gripper in mine but again stripped the teeth off the c.w.p supra now but obviously not tested yet as mines in bits. Ford 9inch is serious money but again rod has another option that seems un breakable with the Daimler option he has

Adam-M

Useage is the most critical part in your decision, if you want to use the power in normal road conditions then it's a no brainer going for 4x4.

Fullflush

You want to speak to Andrew Gallagher.

The car is 1000bhp, gets used harder than anything and is reliable (and 4wd) - all unlike Rod.

henning850

no no, for now the most critical part is to find more then 2-3 people that have the same ide of what working and not working lol

Caddyshack

Lol, yes, I meant the Ford version, I didn't know about any other.

bj928

the t5 was available back in the day as a 4x4, it was fitted to jeeps, i believe the cj7, also, there are people out there converting the t56 and tr6060 to 4wd as its something i have looked at with a previous project i was working on.

Rod-Tarry

Sorry Andy but what 'Rod' did is not relevant in 2017. My box was fitted in 1999 & the 10.5" Diff in 2002 great back then but ancient History now. This new generation of big YB builds will move on from what us old timers did. Wish this guy well & its good to see big Power is still being sought after that's rare these days.

ajamesc

Still relevant two the people actually doing it rod fook the haters

Adam-M

From the pic you posted on your engine thread it looks like you already have a 9" rear diff?

stevieturbo

Yes that will hold the power very easily, and it will go many many miles without needing any work done.

They're in Lithuania, so no need to buy from the USA.

And they have a dealer in Norway among many other countries.

Or cheaper still, you could opt for their universal H pattern gearbox, but the sequential would be more fun for racing.
