oh i see

 

i suppose as long as the points i made are ok and the oil pump pick up is ok then could be a good mod

is that part under any stress thoe?

i can only realy think off it needing to be strong if a rod trys to shoot through it, but if that happens youll have bigger fish to fry.

 

i have that kind of thing on my rotory engine but its trying to twist constantly. just not sure its needed on a 4 pot?

may be wrong , just worth finding out.

wouldnt that mod need a longer oil chain and pump pickup? surely taking the oil pickup a further 10mm from its resevoir isnt going to be healthy for the engine

looks to me like it may have a dry sump anyway...

[dcc 855]

distinct lack of oilpump might suggest this. my bad.

that also looks like a ford lump as well or may be vauxhall

 

dont know why i didnt spot the first time

I'm just worried that the block will flex under high torque. Mi16's spacer plate acts in the same way, but I'd like to connect it to the bearing caps as well to strengthen it even further.

 

EDIT: it's a 2.2 Audi engine, for those who wanna know

Very similar to that used on 3 bearing imp engines to stop the block twisting under mega revving load conitions.

How much power are you after?

 

I can see the point on the 5 cyl audi engine as these regulary run 900+ Bhp but an Iron block in a 205 is always going to spin the wheels long before block flexing becomes an issue.

Not quite decided yet, but it will probably surpass 500hp mark.

Anyone?

 

 

OK, lets go on... what about the top of the XU10 cylinder? That cross-drilling is boggling my mind, if the block is bored out to 86.5 or 87mm and boosted, things might become a bit tricky, but on the other hand, if I go for 1.9D block I'm worried about cylinder crack or even piston seizing.

 

What about "sleeving" the block like this?

 

 

 

Thanks

Sleeving should work, I was concidering that when going to 88mm bore, but I believe it will prove to be expensive!!

86.5mm bore on standard block I guess will take 1000bhp if you want it to
