Certainly seams that way. I think you can get a slightly bigger inlet onto the standard valve seat (40.5 against 40.0mm) but its a lot of work for the gain. yr going to need to go up about 1.5 mm for a worthwhile increase. Who done the head originally ?
BBR (GTI engineering ) did the head and valve work... i cant do the 'LINK' to the NOS kit that i am after , but if you type in 'wizards of nos' on e-bay,there is a used kit on there with direct port injection and a progressive controller.
myne has C&R 1.9 fully balanced short block 8v gti TSR Pack 'A' gasflowed head TSR 272 cam TSR 4 into 1 manifold with flexy joint Scorpion full system Prima power Superchip Cotten and green induction Over sized valves Uprated tsr gear linkage system Custom short shift system Vernier camshaft pulley and i got a 15.671 @ santa pod not bad considering that i havent had her set up yet.
what a mission to get theses parts !!! dealer wants 63 for 8v friction disc and 72 for 16v pressure plate. looks like a Black Diamond job then ? or a 300 group a clutch ???[:^(]
Pretty sure theres something up with mine. Got rebuilt tall block, big valve head (tsr), flowed manifolds, etc, etc. Only managed 140@5400 and 144@4800 at stealth. Got my suspicions about the cam but not going to point fingers at persons who aren't around to defend themselves anymore.
well engine finally run in running : BVH / 276 newman cam / 2L block (2 e )/ standard ported manifold /2.25 " custom exhaust / cone filter / chip (off e-bay ). had it flatout racing civic v-tech. 5th gear was @6500 rpm [:^(] [:^(] and speedo was way off the 120 mph mark. what a differant car to drive still got 50 shot nitrous to come.
With TSR no longer around, where else can you get hold of the blanking plate for the breather? I have seen pics of the 2E blocks with the breather on and it seems that if you take the breather off the block, you will be left with 2 holes, the other being in line with No.2 piston on the block, can this simply be plugged with a core plu or is there another trick to this? Also, the larger exhaust valves (35mm?), are they standard from any other vehicles in the VAG range? (just to make it easier to try and purchase the correct parts...)
As for clutches, I'm running a 2.1 16v on 45 webers, which with the cam timing WAY off pushed out 174bhp and 166lbs/ft on a standard 1.8l 8v second hand clutch. I've been running it now for a week with the timing reset and the difference in power is exceptional, and still the standard clutch is holding out. I know clutches fail, but are people doing 7k standing starts with them to kill them so quick??
