choice for a camshaft

Hahahahaha
Yes to everything you said
Yep I'm trying to get 40 series pistons .
funny , I now have to go to scoobydoo dealer in the morning to get some parts for wife's wrx so while I'm there I might stir the pot , hehehehe
I have to sit down and work some numbers for stroke and what not , not my strongest attribute , I'm only a spraypainter

The main things you need to know when calculating t4 engine bits:
Stock deck (top of jugs with no spacers or gaskets is ~202.5mm.
Decking the case reduces that (a little), spacers make it wider.
Going narrow is harder than wider, jugs need shortened, pushrod tubes etc.

Going much wider than ~3mm/side makes fitting stock cooling tin progressively harder.
(up to ~3mm is fairly easy)

2L rods are 131mm long, 71mm stroke, 50mm rod journal, 26mm wide. (almost same as Dodge 2.2L//SRT4 rod bearing, rod can be modified, thank you type4unleashed, much better choices in bearings)
1.7/1.8 are 127mm long, 66 stroke, 55mm rod journal, ~26mm wide. Ti diameter but wider. 42mm compression height.

Stock 2L piston compression height is 36mm. (center of pin to crown)

...So...stroke/2+rod length+piston height=actual deck
2L: 71/2+131+36=202.5mm, usually leaves the piston almost even with the top.
1.7L: 66/2+127+42=202 usually leaves the piston .5mm down the hole.

Thanks for that info , makes it a bit easier for me to come up with a plan
I'm keen on a stroker but It seems a shame to not use some factory parts I have stashed away as there have been some good results on the forum

Hi,
My engine case is back.
I plan to send it for control and modification this week.
I have a new question about camshaft
The bas 296 ( schleicher ) ? Can someone give me a return ?
