Fitting a 1.3 injection engine into an SJ?

[twiss]

I've managed to kill 3 1300cc engines... they can't be that good!

My mate's had a 410 since I put the 2nd 1.3 engine in mine and the 410 engine is still perfect and he thrashes it a hell of a lot more than I do!
Shame about the rust everywhere else

Yr my 1.0 sj with 5 speed box with janspeed manafold and straight threw exshaust with cherry bomb keeps up with my Mates 1.3 sj and I have over taken my Mates 1.6 vit easy

An SJ413 engine would give a 40% power increase, a Jimny engine would give a 78% power increase and a Swift GTi engine would give a 122% power increase. All those options are also considerably lighter than the 410 engine.

These engines will give you more HP, which is great when you're revving the nuts off it, but it's torque that makes a car more driveable, and none of the 1.3's have significantly more torque than any other. So a GTI engine won't necessarily be a better engine - especially offroad, where torque is king. There's a reason why everyone swaps in Vit 8v's instead of GTI engines!

If you're going to go to the bother of putting a fuel injected engine (with ECU etc) into a 410, then talk to Ladaman about his M15a upgrade. The M15 kicks the crap out of everything but a J20 for torque - even beats the 1.6 vit engines (8v and 16v) by 10-15ft/lb, whilst being more efficient.

You'll double an F10a's torque whilst still being under the 1550cc tax limit.

Honestly, though, it's all a LOT of work and expense. Just get the bigger tyres on your SJ and see how she runs before seriously considering anything like this.

ive driven the zuk with the 31's on a couple of times and she really does struggle to pull away, i love the idea of the m15a, but im sure that would be really expensive to buy one? and what gearbox to use? what adapter do i use? ill have a look at his thread again and see if he has said what gearbox hes used and how to make it fit..

i dont want to rev the nuts off the f10a and blow it to bits lol, im not really used to a high reving engine, i suppose ill probably get used to revving it now with the bigger tyres and will see what conversion i can do when im 21... (in just over a year)

Well the 410 and Sammy gearboxes have almost identical ratios apart from the Sammy having a slightly lower 1st so ithe engine will still rotate at exactly the same rpm to give any given speed but just with an engine that doesent like to rev instead of one that does.

If you don't like screaming a F10 that loves it I don't think you will enjoy belting a G13 at the same revs. The top end will be gutless!

Probably why I used to have a top speed of 50mph with my G13

I second this motion. The F10 is happier if you keep the revs up and change at 4/5 thou. From what I gather it sounds like the G13 would rather be up a gear when compared to an F10 most of the time, and if setting off is the problem then you either want an arse-load of torque or lower gearing, not higher.

I think Anton was the one that suggested it a while ago, what about a 1.4 diesel from a VW Polo? A lot of people on here view diesel as the fuel of the devil, but I'm not so against it.

i would like to go diesel, the other thing is what gearbox will bolt to the 1.4 diesel?

F10A engine:
max power = 45bhp @5500rpm
max torque = 54lb/ft@3000rpm

G13A engine:
max power = 61bhp @6000rpm
max torque = 71lb/ft @3500rpm

The G13 will rev higher and make more power at the top end if you get the gearing right.

I suggested the 1.2 3 cylinder ali TDI at some point. The 1.4 and 1.9 are heavy - people who've installed them have regretted it, but the 1.2 (inc turbo etc) weighs slightly less than the G13.

I'm thinking of doing it myself in a few years time, when the 1.2 TDI isn't a brand new, £1500 a pop (without turbo) engine.

120ft/lb and 70hp sounds pretty good to me.

Right now, I don't think it's a viable option, though. Just waaaay too expensive to even contemplate.

A fuel injected G13 swap requires engine, ECU, loom, Sammy gearbox. Pre 2004 jimny gearbox may also work.

A fuel injected M15 swap requires engine, ECU, loom, Jimny gearbox. Post 2004 gearbox (early ones won't do)

I'd say that out of the two options, the M15 would be the best bet - especially if you can find a crashed Jimny and grab the loom, ECU (1.3 ECU's work fine with 1.5's, 1.6's and 1.8's) and gearbox all in one go. I've seen M15's go on fleabay for around £100, which is what any G13 is going to set you back - so I don't think cost should be the decider here (assuming you're careful).
