And so now we finally have a 2054cc SP long block :S, only took a yr and a half since achieving short block geez! 0.050'' deck height, 8.4:1 comp
ratio, Big delays from head work (porting, unshrouding, machining to 61cc each, 3 dremel-knock offs later) and getting deck right. Will it pay off?
Who knows!!?! Now onto rocker geometry... eep.
I love the Jaycee pushrod bling. Pity it ain't topside
Yes the garage needs a good clean / sort
Chris.

Engine looks like it's coming along nicely Chris, will be very interesting seeing your induction setup. 31's or larger tyres in soft sand will be
the test. Hopefully a light touch of the throttle in second gear will see you clearing every sandtrap or hill climb

Thanks! yea she worked hard on the sand last time i drove her with the 31's, even with teh 3 rib. The engine is so tired... you could smell the heat
after a 10 minute drive up Main Beach on Straddie.
Engine progressing slowly but surely. just finalised rocker geometry, but need to grind the swivel foot studs to channel oil a little further down to
meet the hole. Finally got my hands on a lathe and cut the push rods accordingly.
Pics below!:
CB Turbo manifold came in yesterday. Thought i'd throw a quick mock up for motivation. I will need to rotate the compressor wheel housing (just a
v-band). Can't get to excited yet, got plenty more to go. water injection, air to air intercooler, wide band and CB black box with turbo retard still
on the 'to be procured' list. Let alone downpipe and fueling.
Carbs are Dual 32DIS SOLEX on Weber ICT manifolds. straight fit. Will need to clearance the fan shroud for the one the right.
Should have a bit of zing hopefully
I found reports of a 1.8 litre (not vw) with a CT26 starting spool around 2000 rpm, so this 2054 should crank this puppy according for sorting the SP
top end drop. With the low ratio gearbox this spool should come quick i'd assume. Turbo came from a GT4. Turbo was a low km freebie so worst case
just swap over the flanges for a smaller turbo if not suitable.

Is there any reasons you went carb instead of EFI?

Thanks Pete!
I originally bought the carbs simply for familiarity on the vw application, tried & tested and the upfront costs were a bit gentler at the time.
Different senario now though, and efi isn't a bad idea. Might be the next upgrade. Haven't seen many SP efi dubs. Will work with what i have so far,
but will see what the future brings. A vw is never finished right

Actually, SPs are a nightmare to put injectors on the ports right. So going carb might be a bigger blessing than you think.
A quick search on thesamba or shoptalkforums has a gaggle of SP turbos. Check this out...
140hp at the wheels from a mostly stock motor at 20PSI! 158ft/lbs of torque, which is where the real fun is. Your's should spool a bit faster and
give a really big torque curve. There was a similar SP stroker on youtube a while back. I went looking for it but couldn't find the car. Lots of
boost, drag racing and he couldn't kill it. The SP heads really restrict the flow, but that's what saves the engine's life.

The SP heads i'll be using are the big valve heavily ported / polished ones from this thread that I used the manometry test on: http://forums.aussieveedubbers.com/viewtopic.php?tid=102675#pid962366 I got them to flow just shy of 12% better than stock
DP heads prior to unshrouding the valves.
15 psi would be my max I rekon, which I won't be hitting all the time, but it could get addictive. I'd be starting low and then seeing what the
limitations are of heat and fuelling. I think the three rib trans might say no I'd love 120 hp personally. It would probably be triple what i currently am getting from the tired 1600.
I assume with SP injected one would have to have 2 big injectors, one for each side a fair distance from the head and to simply spray a constant
stream similar to a carb jet under vacuum.
Anywho, sooner i finish her, sooner I can get to Fraser Is! (tis the dream; map is on the wall).
