TEKNO TUNER:: DAY 4 of 4
i am flying back to jakarta from lombok. tonight will be the testing night, first time i drove my greatly missed E30 since December 2010... looking forward to it... my plane will land around 11:30pm
meanwhile at Tekno tuner...
the engine is fully assembled, now the gearbox, while swapping the gearbox, Tekno Tuner found another flaw from previous workshop...
pilot bearing is missing!
the flywheel appeared to be heavily lightened which cause too much torque loss, in the end we swap it to flat type.
the dyno result before the AFR adjustment is 232hp with new softer valve spring and header...
indra has the other prints after the AFR adjustment of 238hp, but i forgot to get it off him... more than i expected from M20B29...

TEKNO TUNER:: DAY 3 of 4
TEKNO TUNER:: DAY 3 of 4
more problems, the previous workshop somehow didnt shave the piston like i requested... the piston was out of the block liner by 1.3mm! with 2mm gasket thats only 0.7mm clearance... hmmmm so indra made thicker gasket for me to made 1.6mm clearance.
Head installed...
valve train and dbilas 284 camshaft installed
all assembled except the rocker cover.... to be tested for naked run...
M20B29 Naked run

TEKNO TUNER:: DAY 2 of 4
TEKNO TUNER:: DAY 2 of 4
the car without the head is being sent to 'Budi Knalpot' to have custom header done
making the collector
longer straighter initial scavenge primary
the tip
meanwhile back in Tekno Tuner, Indra also advised me that the rocker arm is grinded by previous workshop... we didnt have time to source for replacement at that time, so we decided to use softer spring to avoid the rocker arm broke
so all the dbilas springs are replaced with more suitable spring for my lower rev applications. Tekno Spring was made from Kode Steel, suitable for up to 8000rpm...
head under rework
titanium valve spring retainer

TEKNO TUNER:: DAY 1 of 4
TEKNO TUNER:: DAY 1 of 4
its 23rd of May, the Official Race is Friday - Sunday (27th, 28th, 29th May 2011)... time is ticking...
the rough engine sound from previous build... before Tekno Tuner handle it...

i am not happy with the way the engine sounds, so i asked TEKNO TUNER as 3rd party to do a pre-race confirmation check
i am at bali during this time, shooting Tugu Hotel, and indra has been very informative and helpful in everything and answering all my questions. he call me every hour or two to confirm with me before making any changes and he is a perfectionist when it comes to engine.... after spent hours talking to him i am ready to let him handle my engine...
what i normally get from the past indonesian tuner is "leave it to us! no need to ask too many questions as we know what we are doing...." or "if you don't trust us bring it somewhere else"... i was abit shock with these mentality but i had no other choices as i have limited contacts in jakarta...
but what i hear from Indra Santoso from Tekno Tuner was "what do you want from this engine? what are your needs? what else do you want to know? have i answered your questions". i was pleased and very confident all of sudden... after 6 months wait, and after 3 workshop changes for the past 2 years, i think i finally found my ideal tuner... someone who are open for discussion, and able to give calculation to back up his theory... a proper engine builder/tuner...
first, i ask Indra to dyno the engine before he touch it. i was shocked by the poor result... the inital M20B25 2500cc was 167HP and now with 2900cc M20B29, it only made 200hp... with flat spot on the curve.... i am furious....
i asked indra to open the head and not to open the bottom end because i am afraid there won't be enough time
first mistake that Tekno Tuner found was: after the intake port was enlarged, ported and polish, the gasket that was put in between is still original size *smack head*
inspecting the condition and the quality of the head work
what has past is the past, so i will spend time moving forward rather than hassling about the bad past...
indra also found that the gearbox still crunching on 2nd and 3rd, he replaced mine with one of his spare box...
