Turbo F20 H23 franckenstein BUILD **pic's+vid**

[TEckert]

I searched, but i'd like to cet some confermation on this one:

F22-H23 hybrid, use:

-F23a head gasket (why not an f22 or h23 one??)
-F22 tensioners (both)
-H23 Timingbelt
-H23 cranck gear

on my f22/h23 i am using h23 head gasket, h23 timingbelt

[Dutchaccord]

Then ill order;

h23 headgasket and timingbelt
f22 bal belt
f22 tensioners

[SoySauceCb7]

where the FOWK are the videos?

[ACC0RD22]

people use the f23a head gasket because it meets the bores of the f22 and h23 in teh middle . . . f22 is 85mm, f23 is 86mm and h23 is 87mm

[d112crzy]

i thought h23 was 86mm? hmm, ill go search to confirm either one of these.

[d112crzy]

nvm, u were right. h23 is 87mm, and f22 is 85, f23 is 86.

As you know we are doing this swap.

The H23 has a Knock sensor in the block........
The F20/22 Doesn't have the provision to screw in the knock sensor.
How do you guys solve this?

[bracersi]

You can either get a ecu w/o knock sensor. Or you can drill a very light hole, about 2-3cm without penetrating the block and then thread that hole to recieve the knock sensor. We did that with the f20a that I had on the back of the block right next to the oil filter, not that hard.

[Dutchaccord]

thanks man well do that.... shouldent be to hard. I was just wondering if there was a plugged hole that we could use.

Pixx taken, will post up tonight.

The first f20-h23 frank in holland... w00t w00t

Headgaskets compared H23 on the left F23 on the right




F23 gasket on H23 head, note the f23 gasketrivvets interfere with the h23 head. Drill out the rivets.


F20 vs H23 cranck sprockets, also swap the backingplates!


F20 block+ H23 headgasket, checking fitment


Here we'r pulling a plug to insert the waterfeed. We ended up using the big plug on the other side of the oil filter. This bcs the H23 waterplug only fitted this hole.


The next thing we found out was t hat the h23 waterpipe doesent fit the F20, so we need to make a hybrid waterpipe out of the 2... Pjotr is going to do this after he reads this ... lol


This pic shows the hole between f23 gasket and the oil return line on the h23's head. Note the small gap wich needs to be filled with liquid gasket. (see next pic)


The F23 gasket+ liquid gasket




Intake cam in place....


Finished view






We still havent got a place to put the knock sensor..... didnt find a suitable place on the back of the block.

[d112crzy]

do u really want it? u dont have to have it on. just get a chipped ecu(with uberdata), that way ull have optimum performance, since both the f20a and h23 ecu's are not gona be working to its fullest potential.

[bracersi]

Well actually a knock sensor is a good thing. It senses for knocks that come from uneven detonation. If knocking occurs then the ecu is able to sense that and retard the timing to prevent more uneven detonation/knocking. Overall it just gives your engine better timing. It helps your engine to run more efficently
