Hi folks, I've a small question. There's a little hole in the housing on the pic below. I think this is to maintain a flow through the blok when tstat and heater are closed. The waterpump keeps on pumping so you need an open circuit to prevent over pressure after the waterpump. Well... thats...

I like that. Looks nice ;)

Really interested in the outcome of this build! You make it look so easy,

Had an oil leak some time ago. Lost about 3.5 to 4 liters of oil and no sigh in the dash whatsoever. Noticed it on time thankfully sonthe engine was saved. Would've lost it if I had drivin it for another half hour I guess.

Nice. Finaly some more 2.2 turbo's! Have to do this build some time in my life. On the other hand... drivin only 1500 miles a year keeps you happy with only 250bhp :ROFLMAO:

Now 725 + VAT on the VX220 forum at a minimum of 6 buys. http://www.vx220.org.uk/forums/topic/126190-saab-b207-brand-new-engine/page-35

That's interesting cause the GM buildbook says 108 degrees ... :( With 103 exhaust timing the LSA would be 109,5 degrees resulting in 25 degrees overlap.

According to their specs they have 46 degrees overlap, which is 26 degrees more then stock or Comp Turbo cams... The Piper ones should work on a BIG turbo car with a big exhausthousing to minimise the backpressure. My T25G turbo is way to small for that kind of overlap.. In my nissan time they...

Answered my own question again (like to get to the bottom of things) 116 degree intake valve timing + 108 exhaust valve timing = 224 / 2 = 112 degrees LSA This gives a 20 degree overlap with 244/244 duration stock L61 cams. 20 degrees sounds nice (same as Comp turbo's), so no need for timing...

Indeed. I'm still confused on the stock cams.. They are 244/244 duration and according to MarkV they have a 113.4 degree LSA. This would result in an overlap of 17.2 degrees.... That seems very low for a N/A cam and I think it's not correct. Can't find any other information from the stock cams...

Got myself some information. Calculated overlap is 46 degrees which is more than the Comp turbo cams at 20 degrees overlap.

Hi people, I'm thinking about putting cams in my turbocharged Z22SE. Now the Piper cams look good specwise (I want more duration to get some more top) but the question is how these N/A cams perform under boost. How is the overlap with these cams? (less overlap seems better so you wont loose to...

They did a cheap price on the VX forum so it's possible. I would be in if the price is ok. No need for one.... but it itches lol

Yes, I've heared mixed reviews on gapping iridiums. I allways gapped my coppers to 0.8/0.7 mm with good result. I thinks its the way you gap a plug that makes or brake a plug. Seen people put the 0.8mm feelergauge between the sparktip and the (I dont know how this is called...) and then...
