[pandersson]

Hello. Im from sweden and wants your helps. I have a ford capri and   buy a Rover 3,5 engine. Can i use S10  T5 Gearbox and a bellhous from tex V8 tuner to fit ? do i have to modify input shafts length?. Im very thankful for your helps.

Best Regards Peter

Peter, I know the S10 has a lower first gear and shifter location is about 8" forward from Camaro. Bellhousing depends, early had Chevy pattern, later had Ford pattern. D&D can do both.

Peter , what year Capri?

[pandersson]

Ok thanks for answer The Capri is a yellow mk3-79 with x-pack and Rs wheels. are s10 gerbox a good way to go?, i have seen picture when people build forward shift link. i think Cosworth sierra box are dificoult to find here.

Peter, The S10 shifter will be too far forward. It is at the front of the tail housing. There are ways to go back, but usually only 3-4 inches. There is 8" difference with the Camaro.

The biggest problem is WHICH S-10 trans?  World class or non-world class? I4 (with the small input shaft) or V6? Early (with the Muncie bolt pattern) or late (with the Ford bolt pattern)? The shifter location is the easiest problem to resolve, as all T5 tailhousings swap.  There are three shifter locations available - the S-10 (furthest forward), the Astro van (about 8" further back but least common tailhousing to find), and the Camaro/Mustang (furthest back).  The I4 and small V6 transmissions with the 1" input shaft are to be avoided.  The input shaft is weak and first gear is so steep that you'll have to shift before you get across the crosswalk. The Muncie pattern cases bolt to the aftermarket D&D bellhousing.  The Ford pattern cases (GM switched to this in the mid-90s) require an adapter plate that D&D sells.  The Camaro applications rotate the trans 15 degrees, so the shifter hole will be angled if you install the trans "straight up" with the D&D bellhousing.  The Mustang tailhousing fixes this.  FYI, the late 90s T5s used behind the 3.8 liter V6 in the F-body cars came with a factory hydraulic throwout bearing, but these are the Fort bolt pattern.

I think you confused the Astro van shifter location with the Camaro/Firebird, Joe  The Astro van shifter is only a bit over 2" back from the S10.

Also, the Camaro/Firebird shifter hole is straight up.  Only the tailshaft mounting pad & shifter itself are angled 17 degrees.

Many thanks for your answer, wich tranny is best way to go to have good ratio for normal use, ive have seen know from junkyard they have Camaro trans 13-52-065-922 box and olso Mustang Tremec T-45. is one of these better way then S10 trans? for my 3,5l Rover

[ex-tyke]

A Camaro or Mustang tailstock will have the desired shifter location.....but you'll have to let us know the gear ratios of these transmissions, and also the rear axle ratio and tire size you're planning on using, to know if the transmission is compatible from a performance perspective.
Some of the T5 transmissions used behind 4 or 6 cylinder engines have a numerically high first gear ratio and don't work well with the MGB 3.91 rear axle ratio, rendering first gear performance essentially useless.

[MGBV8]

13-52-065-922 is the casting number of the case only.  It will not tell you what engine was used or the gears ratios.  Look for one with the ID tag still attached.

Any reason you just don't use a Rover 5 speed?  Seems like that would be an easier cheaper option over there.

[pandersson]

yes i have not think about it, but wich car gearbox modell from Rover is the easiest way to fit 3,5l and are the  bellhousing  pattern the same? adapter?

[tr8todd]

Sd, but you can probably pick up one on Ebay.  Rimmer bros just started selling new bell housings for cheaper than what used ones were going for.

[roverman]

I just went to Rimmer website. I could not find the new RV8 bell housings ?  art.

Is this the one you're looking for?  Rover v8 to  LT77/R380 Gearbox.

Peter, is your 3,5 motor  from a manual trans car ? If not, you need to source the flywheel and clutch package as well.

There are two Rover gearbox options: the older LT77 and newer R380.Both look the same, R380 is an uprated version of the LT77. There are also different versios of the LT77designated by a suffix letter in the gearbox serial number. LT77 was used in several cars, Triumph 7 and 8, Rover SD1, Sherpas, Morgans etc. R380 was used in MG RV8 and Morgans.

I have had a Triumph TR7 LT 77 for 20 years. It is most likely a Suffix A box (weakest version) but has worked flawlessly. I bought and rebuilt a R380 box years ago but it is still waiting for the LT77 box to break :-)

2 things to note: first; there is also a 4WD version of the box with transfer box. This is not the same thing as 2WD box. Forget it.
second: there are two types of 2WD boxes: passenger car box with 3,3:1 first gear and then the commercial version with 4,something 1st gear ratio. Not the best option for a normal sized car.

Hope this helps.

Don't forget about the pilot bushing.

[pandersson]

Ok thanks for answer. I think after reading that a LT 77 box for SD1 are the easiest and cheapest soloutions for my capri projekt, where in uk can i find / advertisiment after a box ?
