Thrustyjust Posted October 2, 2005 Posted October 2, 2005 Is the K series a good alternative or not very tuneable? The K is very tunable,but to break the 200bhp is very costly and with the others,a lot easier.They also have issues of liners and sealing,so can be more tempermental.Ask my neighbour,who's standard road cars just had a new lump,as the liner seal went.

Blatman Posted October 2, 2005 Posted October 2, 2005 Thermal shock is the enemy of the K series. Sort the plumbing and it'll be fine BUT it's a 1.8, so it's hits power/reliability laws of diminishing returns sooner than a 2.0l would. And no, you can't make a K series a 2.0l with a rebore... Quote
Mark Stanton Posted October 2, 2005 Posted October 2, 2005 And no, you can't make a K series a 2.0l with a rebore... But you can make an ashtray, paperweight or coffee table from them 200BHP region from a 1600VX is easier than a K and still retain reliability Blue torch paper lit ................waits for fireworks Quote
Blatman Posted October 2, 2005 Posted October 2, 2005 Would that be the fireworks from a 1.6Vx engine that lives in the Middle Lands somewhere Quote
congorobot Posted October 2, 2005 Author Posted October 2, 2005 Tempermentality is not what I am looking for, so looks like K series is out the question then. Looking at the pictures of engines for sale on ebay I am left wondering about the intake manifold side of the engine. The air intake plus other bits look massive! How are they made to fit under the bonnet? Does this require buying new (and expensive) throttle bodies? Quote
Blatman Posted October 2, 2005 Posted October 2, 2005 You ditch the standard inlets and fit either DCOE Webers or throttle bodies. A pair of DCOE's plus inlet manifold and filters should cost around 500-600 quid all in if you're careful. TB's will cost you well over 2 grand all in. That includes roller time. Quote
congorobot Posted October 2, 2005 Author Posted October 2, 2005 Was reading in practical performance car about building throttle bodies from scratch. They had done it for a x-flow for about £200. Hell of a lot cheaper than £2000. Was really wanting to get away from carbs but not sure that I am aloud to spend 2K with a forthcoming wedding! Quote

PPC built a plenum system for their crossflow, not throttle bodies... Single throttle and a big box o'air. They did however do a feature on building throttle bodies earlier on, however the feature on using bike throttle bodies is the most interesting. Latest issue. pick a set up for around 75 squid. They're big enough and come with fuel rail and injectors, and custom manifolds are available. Quote
Blatman Posted October 2, 2005 Posted October 2, 2005 The caveat being that you have *lots* to learn about ECU's and set up in the mean time The bike TB/megasquirt cheapness is offset by having to spend lots and lots of time fiddling/faffing, which is fine if you have the time and some already existing skills in fabrication or electronics, or the time to learn...

Tis true, i've tried using a megasquirt and fell at the first hurdle... So we stuck the carb back on as we didn't have the time to sort it, which was unfortunate... But what if you fitted something like an emearld ECU you'd have less faff as they can set them up for you... I think injection is the best idea, it may take a bit of time to get it working, but you could argue that it's only the time you'd spend faffing with carbs every couple of thousand miles... Quote
chappers Posted October 3, 2005 Posted October 3, 2005 What's the difference in power between the 1.8 and 2l? My 1.8 zetec with 130 cam/jenvey throttle bodies/Raceline exhaust (with Cat) pushed out 157 bhp at Northampton Motorsport, whereas Adam1330's very similar spec car with a 2.0 with jenvey throttle bodies/Raceline exhaust (without Cat) pushed out 177 bhp. So I would guess there is roughly 15 bhp difference between the 1.8 and 2.0. I'd get a 2ltr if I had a choice even if was a few quid more expensive. Cheers Kev. Quote
