    the 1.8t VAG engine is a common swap into all kinds of smaller cars,I went to Brands hatch to watch a track day and a local VW meet was on as well
    must have been 40? 1.8t swapped cars,polo breadvans/coupes/estates,mk1/2 golfs, mk3 golf estates,audi 80 and lupos
    watched them leave and surprising how rapid they were,most of them lit up the first 3 gears and limiter bashed into the distance
    cheap power but traction or lack of it is an issue

    Doh, didn't realise what you were thinking of mate. Yeah VAG 1.8t every time, everything you can think of has already been done. Makes life easier.
    Loads of cars doing ten second quarters with it.

    1.8t in an Elise would work for me.

    the Ibiza would work out ok and probs uses the much stronger 1.8t 'box , the polo has a weak gearbox (another 4 speed low power box made into a 5 speed)
    see lots of gti ones cheap with dead gearbox's, common fault is the selector shaft seal leaks at low miles(its very low in the casing as well,another design flaw)
    and unchecked the box runs slightly low on oil and 5th is starved of any oil as the casing is badly designed for oil feed to 5th
    and they soon get noisy and break, tbh there are not many fwd 'box's that cope with big power like 3 times the stock engine makes
    some fwd Hondas (turbo drag cars on slicks) can handle power and then the same car/gearbox can fail at stock power randomly
    I like the 1.8t in an elise idea,just getting an elise cheap is near impossible imo,they don't crash very well(more shatter into bits)
    and 2nd hand clamshells are stupid money anything attached to lotus is tbh,
    cheaper alternative (but 250kgs heavier/less sharp handling) toyota Mrs (mk3 Mr2) are really cheap

    Yeah, Elise 1.8t was a good idea ten years ago. I guess it stuck with me.

    Something else that would be silly and easy, LSMX5

    Can't be Sunny 120Y. 120Y was RWD.

    Can't be Cherry 100A/120A as that was in sump like Austin Mini gearbox. (as Datsun A series was derived from a BMC A series)

    Nissan Cherry N10/11 in 1978 was FWD it only had E series engines derived from the A series. The Sunny B11 was first FWD sunny in 1981 also with E series engines. Then came the 1982 Stanza which had CA16 engine - that would have needed a new bell housing but none of them made more than 100bhp. Mid 80's they made the T12 Bluebird with CA18T with incredible 129bhp (same as Silvia), that was possibly the limit for the gear box.

    Without sounding like too big a prick, there's a shed load of nonsense in this thread....

    The strongest front wheel drive box is p11-144 one, will take abuse easy enough and there's been the odd one ran in excess of 350-400bhp. DependIng on power goals there's plenty of engine options, over the years plenty have turbo'd the standard DE, gtir swaps and more recently VE+T set ups too, but sadly the rwd ones won't just bolt in.

    Gtir boxes range from fine to fragile depending on how you drive them. They aren't some ancient fragile box, the gtir box isn't a fwd box either, it could have been stronger but some survive for years at 350bhp, some get launched relentlessly and don't last at standard power. I'm certainly not aware of Nissan spending money building a rally car that couldn't even finish a single stage.....

    it was well documented/reported back in the day that the group n cars had gearbox problems and I thought common (ish) knowledge
    cars didn't finish the event because they ran out of spare gearbox's
    and if it wasn't a fwd 'box with a transfer unit for the rear drive what gearbox was it based on ?

    Your only looking at Nissan as a uk company, they produce a shed load of models we have never had over here and that's likely where the parts originate from, U12 bluebird shares the same gearbox for example. They did produce a gearbox that was essentially a front wheel drive box with a transfer box but that wasn't used in the gtir or any turbo application, it was used in cars with 4x4 and an sr20de (p10 t4). The parts bin was well used in the U.K. Market but once you start looking at the JDM models it's way more widespread

    So did the gearbox suffer from a weak casing and under-sized bearings like Andy mentioned or was the design perfectly fine but the end user a total animal?
