So heres my Dilemma.

When i started my build, i bought the 2.9 early so that i could make dure it fits.
Long story short, i bought a Dutton which has the 1300 Xflow in it.

Ive since bought a spare 1300 Xflow block, crank and +.090" pistons which are already fitted.

I tried to sell the V6 on fleabay, but TBH i wasnt that interested in getting rid as i really like the engine. I became addicted when i had my 2.8 capri and always wanted to fit one to a kit car.

So. Here are my two optons.

Rebuild the spare engine to a high spec, to cost around £400, and end up with a sweet Xflow 1460cc pushing around 100-120hp+. I would use the old engine as spares, and rebuild it then sell, leaving me with the better engine. Thanks 200mph for the manifold, and RustyNuts for the head offer (no jokes please!!!).

-Or-

Fit the Cologne V6 knowing ill have to move the engine mounts, make a custom exhaust, fit the inlet manifold and carbs etc (which is uncharted territory for me), and get 150hp from the standard engine.

I know (Mr Henderson ) that ive bored wveryone with these questions before, but this time ill be a bit more scientific in my search and provide the poll above!

As above, i have always wanted to put a cologne V6 into a kit car, so by doing so would put a big tick in the box for me, especially as i abandoned the scratch build.

Both options allow for a period of "Tidy Time" whereby the additional space where the engine would sit would be handy for tidying wiring, cleaning / upgrading front brakes and suspension, replacement bushes etc. so either way the existing engine needs to come out before or after it goes bang.

So there is the case your honour. Look forward to your constructive comments.

There is a third option in the wings, which is a new RV8 with stage 2 heads, but lets keep it simple for now!

You need another option...

And I thought one of the poll options would have been "Cos I'm an indecisive Jessie"

On face value it's a no brainer to me to fit the v6, you want to use it, plus there's more power. However does that more power mean more speed as the xflow is a lighter engine and 30hp down...

Apparently (sez people on here) the Rv8 is about the same power so unless you've getting a damn good one...

Personally xflow because the cologne is mad heavy in comparison

i vote crossflow too.

if you want V engine, then go to rover v8.

put the xflow in and save up for a RV8 in a few years

Lol, Love you too!!!

if you are going to spend £400 then why not get something like this Zetec ?

1600 x flow would be better than a 1300!

id get a 1600 block/head and use the pistons in that!

Neither - fit a Zetec.

Im Biased (I have a 1600 xflow dutton). I think it's the perfect engine for the car. it would be an easy swap too.

Isn't the 1300 xflow a requirement for some race category? Use that and race it

I'd look at it this way - the v6 makes 50% more power , but weighs about three times as much as the crossflow.........add to that a second exhaust , and a bit of extra bracing to cope with the heavy engine - it's a no-brainer
Go with the crossflow - or a lighter V6

As above (a long way above), you need a third (much, much lighter) option.............

If you are determined to use one of these two, it would be the crossflow everytime for me. The old V6 boat anchors sound lovely, and they have plenty of torque for dragging big Granadas around, but they weigh as much as a small planet.

My choice would be the 2.9 v6 - after all, it has the correct number of cylinders!

I cannot believe it weighs three times as much as a crossflow.

You definitely need a third option.

Last choice for me would be the V6 - that V6. Nice alloy quad cam V6 with 24 valves is a different matter altogether.

Unless you actually want an understeering monster.

I understand your predicament, I started with a 2.6 Cologne Capri donor (bought it new). Then found a Toyota Corolla GTS, (4age) which is what I am now using, still have the V6.

To make the most of the V6, you would need to give it longer legs - about a 3.4 diff ratio, with a 4.11 or 3.89 diff like with the 1300 it would rev it's nuts off, the long legs make use of the torque through the gears and being able to stay in gear longer - this is what would make a faster car.
The cologne doesn't like to go above 6000 rpm and would suck with a low diff ratio.

The cologne ain't that heavy, not much different to a pinto. The essex V6 on the other hand would weigh as much as a second locost stacked on top.

With the right gearing, this would be a lot of fun, especially on long winding roads - ooooohhh yeaaaaah!

This calculation is with the V6;

Km/h RPM (in Gears)
-------------------------------------------------
1 2 3 4 5
-------------------------------------------------
10 1530 826 574 419 344
20 3061 1652 1149 839 688
30 4591 2478 1723 1258 1031
40 3304 2298 1677 1375
50 4130 2872 2096 1719
60 4956 3447 2516 2063
70 5782 4021 2935 2407
80 4595 3354 2750
90 5170 3774 3094
100 5744 4193 3438
110 4612 3782
120 5031 4126
130 5451 4470
140 5870 4813
150 5157
160 5501
170 5845

These figures are maximum with the gearing i have at the moment, and with a taller diff, would only increase the top end by 20mph.

But how nice will that V6 sound :-)

It only increases top speed a tad, but it affects the over all ratio through all gears and allows the torque to work. With a std escort ratio it would be like riding a ten speed and having big strong legs but using the lowest gear, all they do is flail about, but in a higher gear the power pushes a lot better.

Just like a RV8 is a waste of time with a low diff.

Well, it looks like the Crossflow then!

x flow. I have a heavy powerful engine, and I wish I had light and small. A lot of problems occur because of the lack of space left over after you put a great lump in there.
