i use CAT diesel gasket compound.
that sh1t NEVER leaks.

had my stocker A12 at 6200 in fourth with TRX rims and 195/50 tyres and it jjjjjjjjjjjjjjuuuuuuuuuuuuuuuuuuuuuuuussssssssssssssssssssssssttttttttttttttttttttttttttt made 100mph with a slight tailwind.

then it went bang, there was lotsa smoke and it sounded like someone had slipped a screwdriver in thru the sparkplug hole.

and it looked like that too.....

i believe the great debate was that epic of a thread about a whole lotta nothing. something to do with it not working, lots of surging etc.
i'd sure like to see the doubters with their feet in their mouths now, and to refrain from posting about something they have little experience with.

anyway, glad to see how strong it is.
what turbos are they? IHI RHB4's?

so.....? do you want it or not?

okayyeeee.....
dunno about the whole A12 top end on an A15 bottom end.....! that's just a recipe for a slug of an engine.
i would think more gain would be had in the area of inlet runner lengths, exhaust header design and camshaft selection.

inlet runner design - google for David Vizard Calcualting Inlet Runner Sizes. massive read. i think it went something like this.

1) you need to have the same amount of runner volume as the combustion chamber you're filling.

2) start with a 17.8cm runner length for peak torque to occur at 10,000rpm. for every 1000rpm down the rev range you want peak torque to occur, you add 4.3cm of length to your runner.

3) so, say your A15 has a cylinder volume of 375cc, then for peak torque to occur at 10,000prm we get a runner length of

2(3.1416 x r) x 17.8 = 375cc
reverse the formula and we get a 33.53mm

i think it has horizontal AND verticals....haven't looked at it in ages. i drive a series one (stamped stainless grille) so i don't see it too often.

the SSS grille has a small 'nose' in the middle of it. looks good too...

do you want them?

series one or series two? series one has the indicator on the front guards, and series two has the indicators next to the headlights almost as part of the grille.
i have 2x series 2 grilles, one is a std grey issue (poverty pack) mint cond, and another is a black SSS grille, with a small crack around the headlight recess and a slightly bent chrome piece - all very fixable.
note the grilles don't have indicators with them at all.
what would you be willing to pay? i have no idea what they're worth, as i've never sold trims like that before. just after a fair price, plus datsun1200.com discount

yeah like i sadi, not my experience, just what i was told.
it would more than likely make more power in modified form than an L20.

but if you're looking at something different, i'd go the KA24DE.

200B seats fit well, front to back they're the same bolt spacing, but side to side the seats are a little wide. an adaptor plate out of 4.0mm plate will fix this, so will welding the seat to the runner like i did.
