Middy Engine Choice... Suggestions Please!
Right... pretty sure the next car will be a Sylva J15, so planning ahead. What engine... ???
Can't say I'm all that familiar with transverse engines and boxes.
Looking for a donor engine / box with:
Good Power
Low Weight
Slick Gearbox (preferably with LSD)
Reasonably Priced
The first that springs to mind is the K20 Type R engine, but it's a wee bit pricey.
I'm not discounting anything, so K-series to Sigma to Toyota to Duratec... etc. etc.
What do you think?

3SGTE out of a SW20 mr2?
Should giva a lot of hp for not tooo much money (and you'll be running a stock engine, thus reliable)

Why don't you ask JP himself what he's done so far ?
Honda does sound like a good idea though.
Have you looked in at www.jpsc.org.uk ?
P.S. Good call

My better half drives a honda accord type s with the ka24 engine, 2.4ltr 200bhp which is a little restricted in standard form, much cheaper to buy
than a type r lump and the same size.

how much power do you want ?
Pug Gti6 is 167 bhp with 6 speed box. They are all alloy and can be charged to over 400 bhp.
They are cheap
Down side for a midi is they lean back.
Kv6 from a Zs or ZT 175 and 185 bhp again all alloy and chep while they run

Cheers guys... keep em coming!
I had a chat with JP and he prefers the Sigma as he enjoys the 'balance' benefits. He's open to anything though.

I would go with the designer.
The Sigma is light and that avoids having a heavy lump over the back end with no danger of getting much of the weight over the front end.
Look where you'll be sitting. How much work will the front end be doing ? Now imagine a heavy engine.
I would take a slightly lower powered but better balanced car any day of the week.
In my old Sylva, the seats are pushed way forward compared to a seven and the engine is also way behind the front axle too.

Just thought of the Nissan SR20VE, the 20V version has 204bhp out of the box with dual VVT. They're supposed to be quite revvy (you can see it
as the FWD competitor to the BEAMS SGE) And they go fairly cheap iirc.
There's also a 1.6l variant with 175bhp, if a 2l is too heavy

I'm just a little put off by the Sigma's power figures... seems 120bhp is pretty much where it's at.
The Duratec is not a lot heavier (10kg's), but easy for 200bhp.

Fair enough.
I'll give you that.
Just stick with something acheivable
P.S. 1.7 Zetec S can make much more than 120bhp

Well, it's not out there, it's in here if you like. (See V8kid for details.)
However, I reckon it's fair to say that there is an element of Skunkworks about it as I understand it.
i.e. it doesn't exactly have JP's 'blessing'.

Have you thought about a transaxle? Ive got a midi that im currently in the middle of putting a 2.9 cosworth V6 attached to a UN1 to replace the old
renault engine that was in it.
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.
Kindest Regards,
Richard.

I could use the RS4 V8 engine and 01X tranny that I have, but I reckon the extra 100kg over a Duratec, etc. set-up would completely unbalance the
car.
Besides which... I will probably have to sell it to finance the J15 project

As a data point, I'm using the K24 lump in a project and accurately weighed it. 403 lbs complete, engine, intake, exhaust, alternator, tranny,
and axles.

Is there a front-wheel drive gearbox that will fit to the Mitsi Evo engines?
