Hey Nic, still have the dump/front pipe? Pick up today/morning 0455262778
-
probly due to shit roads and big rims. nissan is run by a gentleman's standards. if it was a corvette, they wouldn't even give you a reply i reckon.

Can I contribue to this? I got 'atmospheric pressure' where LOACH got 'high pressure' im sure it was translation typo.. and sounds like the special tool they have/use does a vacum pressure test on this Boost Sensor. thats why the table line two shows a -47kpa instesd of a +47kpa. sorry if this is what someone has already said. cheers! edit on grammar!

you get knock from more load on the motor on the same management settings, second gear is more load. but there's many other reasons. Im not an expert tho
-
I think your motor knocks bcause of rev-limit lean out. the Power FC (like stock ECU) cuts fuel as a rev limiter, opposite to the desired way to cut spark to stop combustion. this is the way I understand it ( drunk blurb ), You can get knock couple of ways, and possibly others but lean fuel mix and hot combustion would do it. knock on the limiter is bad but it's not as bad as knock under load cos it's duration is longer. stay off the limiter or diy and upgrade fuelpump and fix the voltage on the fuelpump wiring. making the fuel richer all round might make the car feel sluggish tho. Octine booster off the shelf didn't seem to work until I put some NF race octine booster (6 ron). It reduced the knock level on PFC, from 74 to high 20's. and even after hitting the limiter at 7700. handset is good for recalling all readings too. Im curious to find out the limit of stock RB series motors. I think it's related to hitting the limiter and leaning out. I thought the upper limit was at 100 on the screen, but someone on early reply got 140! The motor makes most power at... it's best cam timing and leanest fuel ratio. it's probly case by case and a matter of opinion how much before motors usually pop and associated knock reading. I like knowing the RB20 handles being on the limiter better than other RBs when running with PFC. when my car knocked at level 74, stock internal 20 with 84c water temp no oil cooler and 300whp at 20psi boost. so smaller knock reading on the limiter might be ok as long as it's resonable rev for the motor. thats my 2cents

if you got hicas you should do it. much better than unexpected opposite lock at 140km/h

I forgot to add a 'before' photo, so here it is http://i385.photobucket.com/albums/oo299/m...28062009761.jpg extra lock saved my arse in the rain!

My R32gtst has s14 rack (more lock) and spacers (more lock again) and does not rub on anything. 6.5 caster, 3 deg toe out, 2inch lower than standard ride height. I run standard wheels with 205/50 tyres. hope it helps a bit. I noticed the GTR racks a re totally different to GTST. it was as if one side had a different knuckle geometry to the other. one tie rod was longer than the other..also you can buy AM tie rods with integrated spacer and comes with thinner spacers (washers) to give you max lock. Cheers

I love these kinds of fixes. my 200,000k RB20 runs 1.1mm gapped plug and 18~19psi with no probs. change the plugs every 5000k's. thanks for the thread!

Rb20 Turbo Upgrade, All Dyno Results
ZOKU replied to R31Nismoid's topic in Engines & Forced Induction
Retuned the motor last week at AllStars in Malaga. Made 295whp @18 psi, 1.3 bar, pretty happy with that. made 20 odd hp across the board too. the car felt better even from the carpark. Changes made was, Rb25 intake pipe before the throttle (bigger than 20) -$free New pipe was made from the afm to turbo, made from truck intercooler piping (spools faster and makes impressive suction noise)-$free Bosch 044 -$100 lucky score 2.5m longer vacum line to waste gate, open little later -$5 Cleaned air cleaner pod -$free Cleaned intercooler core -$free Leak free Bov! and other air leaks fixed. Run on 98ron fuel. -
thanks for the quick reply! and extra info 3lit3R32! cheers
-
whre did you get the work done? im in perth too
-
everything is a bolt on. it's been done before. i don't see a problem. I just wrote it up because there was no info on this bolt-on coversion. . the warning that comes with it should scare off any incompetent diy'er. some people shouldn't even change their tyres too. it's up to the mods I guess.
-
more lock for sure! 10/10 for what I wanted. sorry to the mods if this was already covered. warning.: modify your vehicle at your own cost. it's not a stepby step guide. warning: IM NOT A PRO! warning: IM NOT A PRO!! Cost: $100 pipe mod $100 auto trans cooler 150 x 200wide $150 s/h S14 rack The rack i used had a 6mm ish rack spacer was already fitted to a stock replacement looking jic tie rods and rod ends these Look like the R32 skyline ones but gold anodised. The stock hose from pump to rack(skinnier pipe) was modified to have a silvia type (S13/S14) threaded hard pipe fitting that connects to the rack instaleed inplace of the skyline one. leave the original pressure sender(?) in the line too (I did). also the rack imput shaft was replced with a S13/180 one. shaft that spans from the rubber linkage to rack including the uni-joint must be used. its 10mm ish londer than the hcr32 one to reach the s14 rack. Lastly, unplug the small coupler on the hicas computer under the parcel tray to get rid of the hicas warning light. must have your car 'wheel -alinged' by a pro. I made mine 3mm out toe. zero at the back. Impression: the lock to lock feels just as quick as stock. feels little heavier to rotate but less turns, so quicker steering responce than stock. I heard Hicas equipped CA18 S13/180 had a quicker responce rack with 24 tooth opposed to non-hicas rack with 26 tooth. but they are getting old....eh I took out all the hicas gear art the same time and plumbed in a medium sized transmission cooler to the hicas pump side and had it returning the fluid to the power steering resavour. it was needed to keep the system cool even at ide!O ther options for more lock is to shave the knuckle stoppers or buy or have a modded knuckle with shorter arms. watch out for binding and adding more spacers. binding happens when the tie rods are pushed out much more than stock and goes past the pivot of the knuckle and locks under the cornering weight. this effect is a steering that jammsand cannot be returned to centre until the car's stationary. so respect the steering system. cheers!

It's a pity it's not in english mate Chiba-kun is awsome. watch it with a Japanese person who speak english? smoky too is awsome goes home from work doing 300km/h on a daily basis.

I almost threw-up on my keyboard!! thats f**ked. I guess he had to finish it:)
-
what, a chic driving! good god. I need to get out more and see the world...
-
bummer about the paint mate. I wonder if they will pay to fix now. but the drift day was good for me. great to see heaps of R32' out there. spotted ANGR33 and voted for him too vid footage http://s385.photobucket.com/albums/oo299/m...032009090-1.flv

Hey thats my car on second pic, cheers for that! Awsome turnout and for a good cause. I forgot my camera that night. hight light was SLR2000 green silvia, good bloke too. and bayside R34 Vspec 2 was nice too. nice variety of cars hey. and black R34 coupe doing short skids in the undercover carpark. wicked sights on the road. got these pics. some cars in the background. http://i385.photobucket.com/albums/oo299/m...20022009459.jpg http://i385.photobucket.com/albums/oo299/m...20022009466.jpg http://i385.photobucket.com/albums/oo299/m...20022009462.jpg

he's awsome thats for sure! I think tires let him down a couple of times. his tires were all bald by the last race and lost grip in the last corner and came second best:( poor nomuken. He's always an under dog in his 4door too. true champ and a funny guy
-
I bet nomuken (drinking dog) will finally take the crown for D1GP this year. love to see it drift. BLITZ might need to bring more tyres to each event! and hand out gas masks to the crowd. but this car still might be heavier than his current R34 (1200~1300Kg?) weight makes more smoke tho. any info on it's weight? it's a good thing he weighs around 40kg. haha
