Building a K 160 Sport engine to beat a Honda...

[Scottish Scrutineer]

Stu and KingK, you have my interest. I like the principle of avoiding the need to change the engine type. This could be very interesting, especially the cost per hp.

Good luck with the project Stu.
Im not racing you, I could barely keep up you in your vx

[jimbo]

I too am interested to see where this goes, as I've always wanted to keep the K. Not sure why, just have a soft spot for it.

Good luck with this project

Sounds good, looking forward to this one

cool, lets see how far we can get with it...maybe beat 220bhp?????

engine will sound good too - promise you that!

Stop getting distracted by the internet and get building.

Excellent stuff. I'll be saving up over the next year or so for engine imrpovements. Like so many this thread will provide a great reference to which way to go for that extra power, either engine conversion or working well on the K. Good luck and I hope it's successfull.

So to define this project;-

To be clear, this is NOT designed to be a blog about building the CHEAPEST 200bhp K series engine.


IT IS a blog trying to build a

1/ totally reliable engine, that will give years of reliable road use free of any risk of so called "HGF' failure, or any other issue.

2/ as best torque as is possible out of a simple wet sumped, 1.8L engine, on OEM plenum and 52MM TB using existing Sport 160 cams, to keep its description as a 160 Sport engine but also DEMONSTRATE WHAT IS OR HAS BEEN POSSIBLE WITH THESE SAME PARTS TO ANYONE FOR MANY MANY YEARS.

3/ to achieve as best possible power with these limitations, hopefully well over 200bhp and aiming for 220bhp - We will see what we get, but I will publish a software projection as soon as I get a trace of the 160 cams to feed into the software.

4/ to use only those King K parts that I deem essential to build a reliable engine, [bar airfilter, exhaust and diffuser, see below[

those parts being; -

a/ a modified OEM water pump with underdriven pulley and KingK design impellor,
b/ a KingK two piece steel, wire eroded oil pump, and oil pressure regulator.
c/ King K valve spring seats and oil seals - because OEM type are now extremely difficult to find in OEM quality.
d/ KingK oil rail and long bolts
e/ King K long colsibro valve guides to support valve better.
f/ King K windage plates and separate sump baffle.
g/ bespoke steel 80mm bore liners - for long life, and I no longer trust available cast cast iron liners.


All other parts will be OEM ie 160 Cams, unmodified VVC type plenum, 52mm TB, or commercially available for many years - valves. but also crank, rods, hydraulic tappets etc.


The exceptions to aid engine performance will be;-
KingK exhaust tuned to 160 Sport cam,
KingK air filter holder and resonant chamber.
a KingK diffuser between OEM TB and OEM plenum of the same kind I ran on my BTCC engine.


The engine will otherwise be blueprinted and machined like a generic KingK engine.

By publishing the build, projections, costs, weight and results I hope this will clearly demonstrate that a totally reliable, similar in performance [I hope[, 50/60kg lighter and also possibly cheaper than the DIY "Honda Conversion" project on another thread on this forum, that will maintain the handling balance, the originality and therefore the long term value of an S1 Elise.


I shall start another thread, about a similar project, for a KingK plenum engine.

This engine will be identical in purpose and in build method, and many parts, however all non OEM parts used will be of my design or specification, and the performance generating parts - ie valves camshafts and cam profile, plenum casting and single TB will all be new KingK designs and production, with the single expressed purpose of achieving the best possible power and torque, as well as reliability - for a road and track engine and have the clear beating on track and on the power trace of the 240bhp na Honda K20s.

OK, taking this at face value...

if we are going to get into a comparision, I want to see it dynoed on TDi's Rotatest so that it can be a verifiable, no arguement figure.

(Quite happy to cover the cost of the dyno time if that becomes an issue.)

Also, just to be clear, we are talking a STD K block, Std crank, Std bore, std head (as in NOT VVC/VHPD/Vulcan/other big valve/port one)?

[campbell]

My understanding is that a standard S160 head will be used as is supplied on a 160. Could be wrong though.

I think we are talking two different engines here the 160 that he hopes will compare with a honda mainly due to his lower weight to power , lets face it a 1.8 vs a 2.0 a 5 speed vs a 6 speed I think he has quite a way to go

And the second one ,his own bespoke engine

however I cannot see any reason why his bespoke engine should be limited to bore ,head type or even gear ratios in order to give a fair comparison as long as its within the honda conversion price

Excellent stuff Stu. I always liked your Sport 160.

What I don't follow Simon, is how come you need to build one for Stu to prove a point. Why can't you just point everyone to some of your engines out there in the World just now. You've suggested several times you have built loads so why not be more forthcoming about cars you've recently built engines for or even any race series they are competing in as that's the ultimate test of any engine.

Moreover, you have an Elise don't you, so why haven't you built a Super K for that?

[douglasgdmw]

Looking forward to the updates, although I have the technical nouce of zero.

However to be a true Stu conversion the car has to be Scandal green like your 1st one
