Hi Guys
Im now tuning my PFC and trying to work out the Optimum VTC setting for R34GTT with a slightly laggy T04E turbo. To compensate the low rpm load before the turbo get spooling at fullboost around 4k rpm, can i set the VTC like 3500 rpm and will it do any damages if it were set that low? Still stock cams but with adjustable cam gears for exhaust side only (slightly retard settings).

this is covered in the FAQ but you typically follow the rule of thumb, keep adding more timing until it kncoks, then take out 2 deg
using datalogit you can achieve this quiet easily by using the temp correction on the hand controller to shift the entier tune up say 5deg
plod around and see how much kncok you get, if its ok, then set that +5 onto the whole map and save the tune
then drive around with knock map watch and back out any cells manually that kncok around 20-30
your typical knock levels should hover around 10ish
this meanst there is enoguh timing in it to make it work hard enough and knock a touch
but take in mind if your tuning it aggressively now, when summer hits, it may knock more, so keep that it in mind
Thanks Paul for ur prompt feedback, u have been very helpful.
Recently in Malaysia the local fuel station start offering RON95 (downgraded from RON97) which i have not tried using until i know how much timing reduction i need to bring it down. The stations still offer RON97 but just want to have an additional tuned RON95 map.
What's the difference between Advanced Knock and Basic Knock?

Hi Everyone
I am still learning using Datalogit to tune my 34GTT Neo. What would be a good timing for the lower load range (L1 to L10) if running bigger turbo like the Garrett T04e? From what i have tried is to lower timing than the default PFC map espescially around the 1600rpm to 3200rpm, i get better response plus using higher gear to cruise. Been trying to find comparison map especially those who has already upgraded their turbos (laggier type).
Using wideband for on the road tuning and my knock level is very low around 1 to 5 max. Anyone willing to share their map as a guide.

Not sure, but it doesn't look like a nismo part number... nismo part #'s are generally #####-RN### format.
Unless they're omitting the first five digits.
Edit: you could save yourself the hassle and order a set of Bilsteins to suit the GTT from SydneyKid on these forums.
It will be quite pricey if order from SydneyKid, since there will be currency conversion plus additional export taxes imposed which is around 30% more on top if freight to my country. I plan of ordering from Singapore then drive down to get it installed there immediately. Will try the part number you gave to see it's Bilstein.
Any chance for which Eibach springs (height reduce by how much?) to match the Bilstein?
-
I can answer this one. Nismo Bilstein Coilovers front Part AA130, rear AA230.
Hi Howie
I found this picture previously before but not sure is that the part number from Nismo or Bilstein. Reason being that some GTT actually was pre-fitted with this spec when bought new (optional items). Anyone can confirm this?

Hi Guys
I am from Malaysia, so far the local distributor hasn't been very helpful so i intend to source them else where. Looking for the Yellow coloured type, so far i know that the 34GTT is a combination of using the 33Gts Front and 34GTR Rear (read this somewhere in this forum). If there is an actual part number for it then it's so much easier to order the right one. Btw is there an Eibach springs that match the Bilstein?
Appreciate everyone's help. Cheers!
-
Im also looking forward at going for the BC Racing setup...looks like you ordered the one for GTT. Which spec did u buy V1 or BR? Hope to hear some positive feedback once you sorted the rear shock combination.
-
i have to say dude, i had a set a of tein ss in my s13 for a year and they never made a sound or gave me a problem apart from the damper adjuster playing up a bit. it didnt affect the damper rates was just a pain to adjust at times. a mate of mine has had his set of teins for god knows how long but they look pretty damn old and are still fine with no noise either.
i havent really heard bad things about the teins myself, only people wishing they got the higher spring rates!
ive had a look at the greddy and they look really well made and they get a lot of good feedback as well, another great brand is ISC, i think if i were to replace mine thats what ill be getting next. they are built well and for a great price!
Heard about the damper adjuster problems on the Teins too. My Nismo is still precise after 4 years using cos there is only 4 settings for the front which need to push & twist to change it. The rear are 8 settings with a knob on the body. I wish to keep my Nismo R-Tunes until there is a proper rebuilt place who has the spec and now I want to try out the BC Racing (aka Greddy Type) which is selling at a resonable price, plus it is monotube. There is no Greddy selling in my country and the closest place to get the BC is in Singapore.
Btw is it possible to fit higher spring rates for the Tein SS since the damper settings are more for the softer springs?
-
Just checkout Quadrant website, B14 & B16 looks like the perfect set, anyone has the part number for GTT? In Malaysia, there is no proper distributor who can provide me price or part numbers for it. Appreciate if any GTT owners has bought these sets before.
-
Nismo & Greddy probably put more testing plus QC on their products. I get some good & bad feedback bout the Teins SS, the only good thing is they are comfortable for street driving. But they lack precision & too soft for track use, plus I heard of early rebuilt after few months of use. That's why i am sceptical on the Teins QC. Hope they do something about it.
Anyone know how many times can we rebuilt coilovers before the wear&tear of shaft is beyond it's usage?
-
Are you getting the shocks dynoed? If so I'd love to see the graphs.
Been trying to get BC & GReddy to cough them up without success and haven't had time to pull my GReddys out to test.
Hoping to know more about the BC on Skylines although other forums espescially the Evo/Subaru seems to like them very much. So far they have the BR specs with option of rubber or steel topmount to choose. Too bad there is no external reservoir type made for the GTT other than Evo/Subaru.
-
The nismo shocks would be heaps better than tein super street. Just get some 6kg front and 5kg rear springs for the nismo's and it should be sweet.
I really like the Nismo's but i the front pair was rebuilt once a year plus ago, now one side is making noise. And recently did the rear just a couple of months ago which i suspect that the rebuilt was not very good, as there is no feel of rebound at all (loss of compression feeling). Anyone knows how many times can the shocks be rebuilt? Been using the Nismo's for 4 years already.
Regards to Greddy Type S, i believe they are the same as BC Racing BR spec series because both body & spec are the same. Hoping someone can give more input on the Greddy which is my preferred choice compare to Teins.
-
I am also contemplating on this BC Racing (BR spec) and Tein Super Street. Hope to hear more feedback for on the track and street experienced for r34 GTT. The spring rate for the BC Racing (8/6kg) is slightly more than the Teins SS (6/4kg). However the BC is monotube against the Teins twintubes. Appreciate feedback and if there is any comparison between both models.

Hi Guys
Sorry for bringing up an old thread. Found an almost new Tein SS for ER34 for sale, willing to try them out after many years using Nismo R-Tunes which are terrific but can be too harsh for daily usage. Just wondering is the Teins made in Japan or are they sub-out to China to manufacture? Are there any fakes around? From my understanding the spring rates are 6/4 for the Teins, would i be able to swap the Nismo 9/9 which has higher spring rates should i find the teins too soft?
Appreciate feedbacks...thanks.

KU36
225/55/16
$161 from option1
Dry Performance 8/10
Wet Performance 8/10
Great Tyre for the price, good comprimise between a track and road tyre and handles the wet well.
Still waiting for the right tyre sizes to be available such as 245/40/18 or 265/35/18 locally in Malaysia. Heard many good reviews in many forums. Still miss my Falken Rt615, anyone tested both to advice which is better?
-
I am still using 34GTR rims on my 34GTT, tyre all round is 245/40/18 for a more neutral handling. My preference would be 235/40/18 front & 265/35/18 Rear on my previous combi.

I am on my 2nd clutch replacement plates for HKS GD Max Twin Plate. Love the bite and the lighten flywheel doesn't lose power on hill climb. Only problem was the pedal height need to be readjusted correctly so that the bite is not on the very last bit when releasing. Would like to try the Ogura Twins as the next replacement with the conversion kit.
-
The BC Racing has 2 models for the R34GTT, V1 and the BR. Go for the BR which is a newer model & design. Since Im from Malaysia, the closest dealer is in Singapore and the price i got quoted for is around USD 900. This is the closest thing to compare with the Tein Monoflex but has height adjustment without effecting the spring tension which is what i like. Happy that some one has tried & tested it on a Skyline. Will give it a go as I have enough of bumpy ride and confusing height adjustment setup.
-
Just changed mine yesterday, in Malaysia they sell the Paraut brand only as replacement water pumps for the RB engines. It fits the RB20/25 since it has the 1 elongated hole to match both. This is my 2nd unit as the 1st one lasted more than 3 years with 100k mileage of city and frequent weekend blast.
Hope the link will give you guys an alternative unit to buy. Btw Im driving a modded R34GTT

Sorry for bringing up an old thread. My front R-Tunes are totally wacked though no oil leak but has a lot of noises.
Someone pointed to this BC Racing suspension from Taiwan. Since they have a dealer not far from where im at, hope for some feedback from any forumers who has tried them on a R34GTT. If you google it, there is quite a number of forum website that gave some good reviews especially the Subaru's. The are bang for buck suspension setup.
-
The R34 GTT 2 dr & 4 dr has the same suspension setup. However for the R34GT (Na) they uses a different one probably a R33Gts type for the rear only. The reason is one of our mates has the GT NA and he has to get a different type than the GTT.
-
^^ That nur coloured GTT has a modified veilside GTR kit.. typical veilside style
the top secret CF bonnet and rear wing is niceThat's a very sharp pair of eyes mate. Anyway the GT wing now has changed. will post up the pics soon. Kinda wild compare to the Veilside one.

Just to share our convoy pics...

Im using the EVC5 and the feature that interest me most is the Boost Map Correction. It works really well for part throttle response since my turbo is kinda laggy. After mapping the more boost in the lower rpm / throttle % opening, the car felt more livelier and spooling of the turbo is almost immediate.
Hope you find the EBC of you choice..

Optimum Vtc Setting For R34gtt Neo
in Forced Induction Performance
Posted · Edited by driftmeister
Today i tried setting at 4000rpm for road tuning (since i hv wideband), car felt very lively and more spirited in town driving. Felt like VTEC effect especially when downshifting or upshifting the rpm will just drop on the sweetspot.
Just wondering whether VTC helps more on low or high load? Would consumption suffer at the setting im running now?
Not planning on doing any dyno runs atm, until i upgrade injectors and cams.
