x-flow engine transplant
Chris71 - 21/8/07 at 04:44 PM

Can anyone give me an idea what's involved in swapping a 1300GT crossflow for something a bit more interesting (probably a 1700 corssflow on twin carbs) the car I'm thinking about doing it with is a Sylva Leader if anyone can tell me more about access.

I've been playing around with the Vulcan website and it seems a 135hp twin carb'd 1700 is about £2900 as a turn key unit. That's more than the car would be worth..... has anyone got any other suggestions?

Why not get a Zetec from a scrap Mondeo for a hell of lot less than that?

Wouldn't it be better to go for a more modern all alloy engine, less weight means more zoom/bhp?
£3k for a x-flow seems a bit daft to me. any particular reason for this choice?

Although I am a keen x-flow owner, I must agree with the above - either buy a stock 1600 x-flow and do it up yourself while spending as little as possible, or spend the big money on something far more modern.

My preference would be for a Toyota 4-AGE - it's physically a small engine that fits well in place of a x-flow, but gives heaps of power straight out of the box (130BHP?) and has scope for plenty of improvement.

Otherwise a Zetec is cheaper, just as powerful and tunable, albeit a bit bulkier (but you will spend quite a bit on bits & pieces to make it fit into a seven).

Have a work with joelP about his zx6 transplant, it cost him pennies.

I have fitted a zetec into a Star / Leader chassis before and can give specific advice if you want.

(I will more than likely be doing it again soon as well).

Just had a look at the RAW Engineering site. Just over £2000 + VAT for a checked-over, complete and ready-to-install 4-AGE.

An added thought - a Zetec is easy to connect to a Type 9 gearbox - the Toyota can be made to fit, at a price. Alternatively you could use a Toyota box, but they're not too common, and also expensive I believe.

Mulling it over, a Zetec is probably the best choice!

Indeed it is. Fits the Sylva chassis better than it fits a Locost chassis.

Zetec is best bet --- or K16

Or if you really want bargain basement without having to deal with electronics a 1600 CVH can be found for pennies -- lots of hot bits around for them.

I would think a 1.8 zetec out of an Escort would be the most rewarding (cheap!) way to go...

Some bike carbs and Megajolt, sorted

Freshly built 1600 Crossflow currently on ebay for £650. CLICK HERE

Easy swap with 1300. All you need to worry about is the extra 1" of height and the slightly deeper sump.

there is always the bay of E; £ 300 should see you with a overbored 1600 in good condition; antoher £ 100 for the carbs, £ 30 for manifold. £ 30 for cam etc.

If you wait and search long enough, £ 500 would be all you need to spend on the engine. You won't get mega bhp but should be up around 20% on what you have in the standard 1300.

I agree - it is silly money (more than the car is worth....) and I'd never pay that much for it - thought it'd be about a grand for a reconn'd engine ready to drop in!!

The cross flow idea is simply because I don't have that much practical experience with engines and I wanted a straight forward swap. I'm told 1300 to modified 1600 crossflow is only a couple of hours job! I also don't have much in the way of facilities here.

However my father has a full on workshop. What's more he has a lightly tweaked 1600 cross flow (in bits, but complete), atleast one zetec (2.0 I think too) and I have a pair of spare CVH's for my Quantum there I'd forgotten about

For SVA reasons he's earmarked the earlier 1.8 Zetec for his Stylus, but the 2.0 is free to a good home (well, me) as are the others.

Mentioned this to a bike mad colleague who's now trying to convince me I should stick an R1 engine in it too! The think is, I've heard people say before that 150hp is about the limit for a live axle Leader, so I'd be looking for 130-150hp, as little weight as possible and a nice simple installation!

For a cast iron lump (or boat anchor as the BECers call it), the crossflow is pretty light. I managed to pick up my engine (minus flywheel) off my work bench and put it on the floor by myself (engine lifter wouldn't reach it!). Almost soiled my pants with the strain mind

How does the 1600 Fiat twin cam compare?
