hello,
what do you think about 1914ccm engine? is it easy to get from 1600i?
manfred offers 1900 tuningchip.....but it is not enough of course
cheers.

There will be some problems...
1914ccm means, that this engine needs a lot of airflow, much more than a original 1584ccm engine. Even with a hotter cam shaft, the air intake, throttle, all ducts and cylinder heads are too small and need a lot of rework.
If the cam shaft is just a W100, then it will work with around 65-70PS. Probably the digifant will also work with this cam. It will drive like a quite normal 1600i just with more torque.
If the camshaft is too hot (>284), then the air flow will collapse and pulsate ... and the digifant will not cooperate. Very bad idle and the engine will not rev over 5000rpm. The digifant is controlled by underpressure... and the sensor is veeeeeery slow.
The probably best compromise between power, driveability and costs is a 1684-1776 ccm 1600i modification with around 65-70Ps.
Everthing else will need a digifant replacement to a free programmable controller.

thanks Red
I can buy cylinder heads that have been already prepared for 94 or 92 with valves diameter 42x 37,5 or 40x36, what do you think??
or should I just drill the std. heads to 90,5 and make simple 1776?
and what about the lifters? standard type IV are ok with engle w100?
best regards |

Hello,
I would recommend to you on case of each to install additionally an oil cooling system since the standard one is not sufficient with this capacity and/or achievement any longer. As oil pump you can use these with entrance and exit (CB Maxi pump 3 with inlet and outlet).
Then you should block additionally again a filter, a thermostat and the oil cooler.
For the tappets you should use easy Tuning Typ-4 tappet (Lifter Type-4 WEB CAM 100g 109,309 021HD).
The remarks from Red1600 to the topic large capacity are naturally perfectly correct. The entire suction plant was originally appropriate to 1600ccm for an engine. The maximum power becomes such an engine with approx.. 4000 1/min.
With the series transmission goes there from the maximum speed not much. The standard speed limiter remains likewise and thus the beetle will become not many faster.
Acceleration and the passage are however better around worlds.
It does not have to make also the money as an expensive change for everyone as Red1600. The moreover one you also the large cylinder heads do not bring the pure use the standard suction plant with Ihrere small suction valve very early to your borders push there.
If you should be correct on achievement out, then would be the optimal solution.
1. New block with crankshaft with counterweights.
2. Piston and cylinder for more capacity, depending upon desire, if necessary also more stroke.
3. Freely programmable controller.
4. Sharp cam shaft
5. changed exhaust or at least the HJS catalyst.
6. Single suction valves plant e.g. VGS and not series the suction tube, since this is much too small.
7. Large cylinder heads e.g. 044er.
8. Many far small articles as, very light tappets, special push rods, resting high voltage distribution of etc..
However then the nothing more has to do with your 1600i engine. I hope help you far.
Greeting Bobby-911

First, if you want the original design of a 1600i: stay with the original 1584-1776 ccm. My recommodation is 1684ccm. The original throttle, tubes and so on will work up tu 5000 upm, with rework around 6000upm.
I have measured, that everything above 5500 upm will create a loss in cylinder filling. More than 6500upm are definitly not possible with the original 1600i parts, even with rework.
Next is, no 1600i digifant can work over 5000 upm, also with no modified chip. Even Manfreds chips do not rev over 5000 upm... there is no way to go over this limit. If you want to go over this limit, you need a free programmable controller like the Trijekt i use. 2.200 Euro is a lot of money for this small box including O2 and pressure sensor
The next limit is the camshaft, it must be a cam, that fits to 5000upm and to the suction system ... and to the catalytic converters. I used a 288 Schleicher with 68 degree overlap. It is capable of running 6200upm and has it's maximum power around 5500upm. But for the digifant this is already too much, too hot. The idle was really bad, if you were driving towards a redlight... dead.
So something around 276-282 degree would be nice.
The 1600i cylinder heads have 32E 30A valves. Too small for tuning. I used the 44 magnum heads cnc maschined with 40E36A valves and 9.5 compression. Maybe this is the reason for the idle problem with the digifant... vibrations in the underpressure sensor.
The crankshaft is a full circle 69mm forged crank, Carillo Pushrods, 88mm full size cylinders, forged pistons, 56gr lifters, very light 1.3 pauter parts for the valves.
Most of the parts are necessary to get everything light to get the maximum of power out of this small engine.
But it works...
With this setup and the modified digifant ( Manfred made a special chip for this engine...) it had 78hp at 4800upm.
The same engine with Trijekt 102hp and gasoline, 115hp with E85.

I must say guys that you've got a huge knowledge about 1600i beetles
I've decided to make a good 1584ccm (a good basic) and next year I will drill it to 1776ccm.
I've alredy bought engle w100 but I can't buy lightweight type4 lifters :/ it looks like I must order it from germany.
I'm still thinking about the oil pump.....if i buy this with inlet and outlet port will i have to make a full flow system? and where the hell will be oil filter in this case
next thing.............you said earlier about 040 heads and temperature sensor? please tell me how to make this sensor?
so id I've done all those things mentioned..........it will be 70ps? or not?
i mean 040 heads, engle w100, higher flow pump
and the last request could you please send me some photos and specifications of yours engines, and cars?
i wolud be pleased
my e-mail baca_69@interia.pl or put them to forum
thanks and a lot of respect
