Wow... I like this tip... I had never thot of this for extremely hard to reach locations (welding rod technique).... Love it! You learn something everyday :D Definately heating then cooling the bolt will help (cool it with the Loctite free and release).. In my experience if a bolt wont...

oh oh... where do i start.. the increased boost gave the extra HP which bent the rod, timing was not touched, AFR's all OK.. HP is dependant on: Engine capacity, compression ratio, RPM, Boost, oxygen content of fuel and air, Tune... did i miss anything... Anyone of these changes horsepower...

Wow... I stand corrected.. hmm.. ur not running pump fuel tho to get 423 are you....? Will need to re-read your build post :) Yep... Meth... nice

GT2560 (320 HP).... I would have to check the -dash number, but was at the limit of the compressor map (the plus 3 that is) Yep... Rods tend to bend at certain power levels or excessive forces applied to them.... a certain "tune" at a given boost will give a certain amount of HP. There are so...

Agree! Rebuilding your 93, make sure you get a new oil pump. Dont run a too heavy grade of oil, I do suspect my last engine failure was due to thicker oil and high rpm caused some cavitation in the oil pump and then failure. Currently using and sticking to Mobil 1 fully synthetic 5W-50

Well before the line.. but that was with the 14's on (evo 3 drivetrain), no not that fast, rolling diametre is a bit smaller... With the 17's on (last turbo) in 4th crossing the line at 117mph at under 8000rpm Yes I am conservatively aiming for a mid 11 (will be happy with that).

I disagree... who runs above 25psi of boost with that much compression ratio on pump fuel??? Comp ratio too high at 9.5 - 10:1 I have the same opinion about "needing" different cams and custom exhaust manifold (as I said mine is modified, the outlet that is), you dont need them. Why spend the...

Rev limit currently set to 8200, My springs are from RPW... cant remember the brand... Current Turbo's compressor map is good for 28psi all the way to 9000rpm... but yeah I did hit the limiter in 4th on the first run for the night

Best I could get was 12.34 sec and 2.01 60ft. Engine would "cackle and pop" with above 20psi... I think its engine water temperature related (engine not quite upto operating temp), tested this theory on the drive home and it appeared to work... Will be changing to a slightly hotter...

Check the very first post the picture shows a spool forged rod.... yes I am using them.. i recommend them highly... Was running a GT2871-15 (26psi), now running a GT3071R-3 (above 26psi hehe), if you have your heart set on the 2871 make sure you get the dash 15 its the most responsive out of...

"milkandoj" - ur gearbox is fixed.... come to the drags and test its strength hehe ^_^ ^_^ no one to commit...?

Open to the Public Its a "Whoop Ass Wednesday" Competitor entry opens at 5pm racing from 6pm cost $45 to race, racing till 10pm. Competition Entry closes at 8pm or 160 cars. If your in the line up to race at 6pm (meaning gone thru scrutineering already) you get an average of 6 races before 9pm...

Ok, Im ready, Tune sorted, gearbox niggle sorted. Now relying on good weather, drags were called of this week. See you wednesday night (Jan 12th) Who's coming?

I would recommend the machinist / engine builder that I have used (times 3), he's also built my mates R32 GTR with a 3.0ltr bottom end..

I have this week off work, yell out, if you want me to drop off my measuring gear, I too am savvy with a dial indicator B)

I have always tapped the piston and conrod upwards from underneath to separate from the big end, then the cap comes off easy... Maybe the pistons are all the same size (to 0.01 of a mm), measure them. If they are all within 0.01 of a mm, it wont matter what bore they go in. Measure the bores...

Brian, I am/ was a Fitter Machinist, I have a set of telescopic gauges (up to 150mm I.D) and outside mics up to 50mm (not big enough i know) also a good set of verniers... And some left over plastiguage.. you have my number... sucks when shit goes wrong..

Ha, good to see "EVLGRL" there (not from this forum) she did a 12.7 that I saw as her first run eva! It certainly was a test n tune night for me, problems galore... no P.B achieved more like a W.B (worst best, lol).. including psteer belt split... I'll be back for more punishment and hopefully...

Ok, I will be there.. more time for fine tuning would've been good, but there's always next time.. its time to race! anyone going to confirm their attendance?

NYE is crap over here compared to the east coast, on a public level.. Australia day in perth is comparative to NYE on the east coast, im still not used to it lol... make sure you go to the motorplex, its a fast track, quality.... lots of traction.. Where are the hills? there on the east coast...
