Iam asking this for my Dad.

Bike engines ahve already been looked into and not ruled out so this for car engines please.

He has an early MK locost chassis car. They are not overly generous in the engine bay height department. There is a x-flow in there right now. We have been looking at engine conversion options. Zetec and red top etc being the usual suspects. It would appear that the height restriction is a limiting factor. The aim is for a reliable 160ish BHP and loads of fun with possible future upgrades.

OK - admission no. 1 - i know nowt about Toyota engines.

Does anyone know the dimensions of the 4A-GE from bottom of sump to top of rocker cover and to top of injection plenum (assuming they have one etc etc).

Any good links to sites that show what is needed to fit them into a little 7?? and later how to tune them easily for a bit more power (i dont mean steel this that and the other, just like cams, porting, fuelling etc).

I guess the other question to ask is;
Any other Toyota engines the same size as the 4A-GE but bigger capacity / power / budgets?

Other makes of engine that are mainstream, not mega bucks and similar dimensions to a x-flow??


If the conversion comes off there may be a complete 1700 crossflow package coming up for sale. Do a search for darrensdad if you need some details.


Thanks in advance,
Darren.

XE and zetec will go under low bodywork, just compromises ground clearance a tad, but no more than a BEC with low bodywork (bike engines are tall too with the carbs on! )

My XE is fitted under the Stuart Taylor bodywork with no bulge and that is caterham height i.e. lower than any other locost.

wouldnt a rover k be a better engine for height ?

Can't help with dimensions, but I have seen a 4-AGE engine in a Locost - it's a very compact package, comparable with the x-flow.

If you want some pictures, have a look at Rob Lane's web pages - there are several there showing his 4-AGE installation.

cheers,
David

Not sure if it's entirely accurate, but this site has all the dimensions of the popular engine choices:

Hi

Converted a crossflow powered Striker to 4age power.

Using a shallow sump (Raw item) the height from bottom of sump to top is within half of nothing of a crossflow. I went for a bonnet bulge and a bit more ground clearance with mine though...

4age's come in various forms, but a latter (Phase3) stock engine, with a mild set of cams in it generates around the 165 bhp mark on Twin 40's - or certainly that's what i'm getting.
(Or go for a completly standard late model corolla GTi as this comes with TB's and produces 150 straight out of the box.)

Other positives are that the exhausts on the right side.
It easliy mates up to a Type 9 box.
It sounds fantastic..
And doesn't look too shabby either..

Downsides are that the plumbing's is a bit messy

So far its been the best thing we've ever done to it, great little engine.

Toyota 4E-FTE. 1.3L, 135bhp stock, easily tuned to 180bhp with stock components. Needs a bellhousing to match a RWD G/Box. Extremely good torquey engine, more compact than the 4A-GE.

I believe the zetec se (yamaha derived 1.6 as in fiesta, focus, puma) is about the same size as a 4age and is an ally block. bellhousings are available from shawspeed, westfield and quantum.

loads of goods available from shawspeed to get it upto 220bhp+ if your pockets are big enough. cams and throttle bodies is around 170bhp iirc, of course the bike carbs/bodies and megawotsit are the locost route..

Ned.

Ill stick some links here for when he reads later (im not answering my own questions....honest!).

Are the larger capacity Toyota engines physically much bigger?

if it fits a striker it'll fit probably any seven, as the striker is the smallest.

I had both 16v and 20v engines in there without problems, exept for the intake manifold on the 16v, that was cut and shut to get the hight line at the same level as the valve covers.

that modified plenum is for sale btw but located in holland lets you use the stock injection and has the filter facing forward (ae86 style)

If I have the time I'll do a measurment job tommorow on both the 16v and 20v engines.

From my experience if you want a compact, reliable engine to bolt in then go for the 20V. Especially the "blacktop" version which comes with lighter internals and average about 150BHP.

If you want an engine you might want to continually upgrade then go with the 16V 4AGE as the parts are more readily available and usually cheaper.

Saying that I'm currently modifying a "silvertop" 20V engine and will probably have some dyno figures in the next few weeks.

I originally installed a stock 16V 4AGE in my Striker as it was easy to get through the SVA and MOT. Later I installed a 20V 4AGE to get a 30BHP power increase but the car was transformed due tot he smoothness and response of the "blacktop" engine!

The thing I like about the 20V is the neater cooling pipe arrangement. All the pipes connect at the back of the head. So nothing neads to run across the engine bay as you can see in the picture below.
