" .. I imagine that as lobe design becomes more refined the benefits become progressively smaller. And how much of an improvement could one expect from using a state of the art lobe of today as compared to an average off-the-shelf design from say 20 years ago, assuming similar timing and lift?...

how do you accurately predict / calc VE at any setting of RPM / throttle position

You can have two situations of same VE but one can have way more density

to suit RH drive lada, yip! the horrible old steering box has got to go
have seen VW mk II slotted in, looked pretty ugly,
love to have something 2.5 - 2.8 lock to lock

I understand they are very similar engines in design, although I don't think anything will swap from one to the other the 2.3 was an american design.. called a pinto ... the 1.6 & 2.0 were a euro design the port on the 2.0 are too big from std. but chamber work makes a big difference http://www....

Anything works on a Lada! For lateral "support" With a Panhard rod for simplicity. There might be a kit available, more or less made to fit Your veichle. Make it run parallell to the axle. However, if you're not familiar With fabricating Your own stuff, go With the A (or X) as mentioned a...

Hey fredi, don't feel down on it... at least you asked
you've been getting some bad advise from outside of this forum
how about some of you smart fella's helping this dude out

camking, madbill, 900hp, malik, and the list goes on

That seems like a lot of cam for a plonker What about 35-75 / 70-40 from end to end @ 0.006" lash hot that'll give you 290* duration, - 75* overlap .. icl of 110* ecl of 105*, and an LSA of 107.5* Lift at the IN valve 0.574 and at the EX valve 0.476" and I bet there's something a miss with...

I've used the 1.89 intake valve but you definitely need to unshroud them. When I first cut the seats for the 1.89 they actually lost flow compared to the stock 1.74. Not until I unshrouded and laid back the chamber wall did it pick up. The euro's new all about these problems with production bath tu...

will it work on me lada

If someone with good memory and computer skills , are willing to look back for a quite in depth discussion on the old 30-30 cam... wasn't that long ago If you think that more than half a century since its design is not "that long ago", :-P Ah yes :!:, I left myself open for that one =D>

The first thing I notice :: is what appears to be a large difference in valve head ratios The valve stem angles appear to be narrower at 35 * +/- the s/plug is close to the ex valve the intake port is high the port flow is maxed out at 25% L/D +/- @ 30 * overall, it would appear the chamber burns we...

who would stick webers on a dog :?: ... if you do, you deserve every flea invested camel known to man why run an IR system :?: ... because you can pulse tune the runner for better performance, usually over a narrower rev range you can run webers on any cam timing you like, but the larger the C/L the...

You're going to need to make peak power at 6,800rpm Here's what you'd need for a cam. Cam# R78453-79431-108 264/266 @ .050" .453"/.431" Lobe Lift 108 LSA I had the cousin to this cam, I would say identical, I would have given it to you, but it slipped out of my fingers as I removed i...

nissan... sr 16 > 20 you'll find that most engines pretty much have equal o/l on IN / EX so set the crank mid stroke ( 4 cyl ) then move the intake so lobe is trying to just open and exhaust lobe is just leaving on #1 cyl reset crank to TDC #1 you might have to jiggle the sprocket to fit the belt , ...
