It's on the list Claire!



Any idea how much bigger the 2.5 is over the 1.8? Or is it just a case of bigger bores in the same block?

All three engines share the same block and heads - they just change the bore , stroke and rod lengths .

Fiesta st150

Why?

Supposedly a Duratec

Comes with a beefed up gearbox

Someone is already doing it into a J15 (so problems worked out)

Its a Ford so the tuning parts will be easy to get and cheap.






If you will ignore this and go for something more powerful. Then don't go bike engine, Tim Hoverd (google him, as his diary is mega) is doing that and it has involved undoing lots of the design (one of those if you want to end up there, then don't start here things).

Best of luck, I anticipate that we won't be seeing "J15 chassis with all the expensive bits at knock down price" in the "for sale" section (shame as I could be tempted, although I will never sell the one I have).

There are loads of options, but all depends if you want to have to make or buy an adapter plate.

V8's are even possible and adapters are available off the shelf. IT all depends on what your target power figures look like, and how much space you have.


You'll not fit one in a J15 (at least not without moving the rear wheels back a foot or two, redesigning the chassis and remoulding the bodywork).

Getting a Sigma to anything much above 130bhp costs a lot of cash, if a duratec fits then it's the obvious choice simply as it's a lot cheaper for the same performance.
(K series definitely fits do I don't see why it wouldn't).

Duratec V6 - fairly light and compact. I just saw an ST200 complete with gearbox and ancillaries go for £350

Or take the same gearbox, flywheel and driveshafts and bolt it to a Toyota 1MZ-FE 3L V6.

As a few have already mentioned, the h22a, 2.2 vtec from honda, at least 185bhp up to 220bhp (type s prelude import). What I don't think anyone else has mentioned is that afaik the '93-'96 prelude chassis type bb4 (lightweight) was regularly specced with a VSD from factory. Might be worth looking into, and the best bit is they can be got for under £500. The chassis' rot like nothing ordinary leaving behind a very entertaining engine ripe for inserting into a kit car. It also has an excellent gearbox as well.

take a look at this on pistonheads if you don't believe me: clicky

Suggest you follow Jeremy's suggestion to use the Sigma for the following reasons.

1. Balance / light weight
2. Great shifting feel
3. "New US Fiesta" will provide more aftermarket parts.

The ultimate solution however especially for LHD is to have Jeremy modify & extend the chassis for a Hayabusa & chain drive. This is a much more expensive Car due to the custom work and parts.

do people know the weights of some of the suggested v6's as I would have thought a ST 200 or 220 would be the natal chouse as its all ford parts asuming it fits and does not weight to much.

have you decided on an engine to use?

Well...........the flywheel is just 3 1/2 kgs , about 2 kgs for ally front pulley's , small alternator (dunno - maybe 4 kgs ?) , then two sets of bike throttle bodies - maybe 4 kgs ?
So - about somewhere around 125 ish would be my guess .
The Duratech V6 may make more power , but it wont rev to 8000 , is close to 50mm bigger in all directions , and weighs some 40kgs more !

The last 1.8 (K8) I bought cost me £50
As they are only fitted to front drive cars , Mazda 323 / 626 and Ford Probe are where you will find a gearbox .
