on another note timing is not moving now i think i forgot to tighten the screens on the top of the points :S hahah also, now on full boost in second gear pulling it hits a cut and backfires furiously which is either fuel or spark i guess any ideas on troubleshooting and working it out?

thanks taz, you wouldn't have links for purchase sites? also should i just a fuel regulator in the line?..

 

new problem I've encountered is blue smoke out the tail pipe, and LOTS of it after a strong pull etc. i can't believe its the piston rings because all 4 cyls where 150psi on compression test, would it be excessive oil getting to the turbo as I have heard of this problem in another friends 4k turbo setup, and just running a hose joiner with 2-3mm gap reduce the oil flow well enough?

You could get a porno pretty much anywhere, dare say Ebay might be the cheapest. A simple carby reg wouldn't be a bad idea, not sure what pressure su's like (waits for Altezza to pipe in lol).

 

What are your valve stem seals like? Smoke could be the turbo. Do you have a nice big hose on the oil drain? And have it on a nice down hill slope to the sump?

Altezza, we require an SU carb (175CD zenith) fuel pressure hahaha :D

 

Valve stem seals are fine, turbo has got a nice big oil drain line but just thinking back it was blowing mass smoke when it was parked on a big angle which would've pushed all the oil to the side of the sump where to oil return was in which case there may not have been enough pressure in the oil lines to push it back out.. but i guess the constant small amount of smoke is turbo overflow from the feed inlet i think ill put a reducer in and see if it makes a difference

Also in regards to mounting the pump.. ive been reading that they are a push type pump not a suck type pump (the mechanical stock pump is suck is it not?)... so just wondering how and where i should be mounting the pump, Probably going to get a Holley Red.... like this ---> http://www.ebay.com.au/itm/Holley-Red-fuel-pump-with-Regulator-Guage-/231173113659?pt=AU_Car_Parts_Accessories&hash=item35d2fdc73b&_uhb=1
