I hope to learn and share some knowledge with you.
I have a Toyota Tazz (weighs 900kg) with a Redtop Beams conversion. I have recently purchased a manual Dual beams head and wish to fit it within the next few days.
We have a handful of Altezza's in our country and the closest to get to experience one is by doing a Dual Beams conversion which is very poplular around here. 1/4 mile times average 13.5 with unopened stock dual beams engine with standalone management, exhaust, downpipe and CAI
Head is fitted, compression is bumped up and this little Toyota Tazz is flippin awesome! Revs up faster, pulls stronger especially at high rpm and sounds insane... Saturday is MSA so I will be running some 1/4mile times.. Have a callout from a 185kw EG Hatch K20z4 so I want to see what happens. Will post some vids soon
