the car is off the road for respray and engine rebuild. Hopefully back this week.

The engine will be stock with a HKS exhaust cam. Running factory turbo and ic. The s-afc II has been sold and a standard safc in its' place.

The rest of the car is still as it was.

the car is back from the camshaft install, needs 500kms to run in the cam then back for a dyno tune and after that and a couple of little bits sorted the car may just appear at the track for a run or three.

The camshaft appears to have added a fair bit of stick even keeping the revs to 4500rpm and the throttle to 50%. The little factory turbo gets excited very quickly indeed.

any more news rev? Just wondering a few things where and how much was your ogura super light flywheel? I also read your how to guide to get stockish GTST into mid 13's (very good time) and was wondering what was the significance of removing the panel behind the stocky intercooler? Have you heat taped ur exhaust manifold? Do you think a cheapish way to upgrade our crappy ceramic turbo is to get an s15 turbo hi flowed? one day i will hopefully one day get into mid 12's on full street trim. (atm i have 235's 45 ratio 17's, but quite heavy rims that cam with the car)

thanx

Rom.

the flywheel is cheap with the current exchange rate. Go find out at takakaira.co.jp

remove the panel and it allows the air to flow better through the intercooler, better still is to make some ducting for it and cut a hole in the panel instead.

I did not tape the exhaust manifold since it is made of cast iron and when unevenly insulated (tape is a problem here) it cracks due to uneven expansion.

The cheapest way to upgrade the std turbo is to add a 55mm TO4 V-trim compressor into the machined out std housing (you need to machine the ditch again in the same way as the stock compressor housing inlet snout has to prevent surge) , then add a VG30 exhaust housing and machine the snout by 3mm so the standard ceramic wheel has extra clearence and agin it reduces surge. BOOSTD has perfected this idea and made 250rwkw with it , should cost $500 or so to do. S15 turbos are the wrong flange and are smaller than the RB25 turbo to start with.

On the news front my car will shortly be sold. I recently put it on the dyno for a quick tune.

The result was around 240rwhp odd, the power was limited to this upwards of 5,000rpm due to the extreeme intake heat (54 deg C ) and the fact that I did not play with the dial in of the exhaust cam. As usual I did the runs with the bonnet down. AFR's where kept in the low 11's due to the heat.

In it's present state of tune a 12second pass on the 205's should be within reach. Even easier if the tune is taken a little further.

Don't under estimate the gains from Heat wrap. Apart from reducing under bonnent temps, the wrap which keeps the heat in and causes increases in pipe temp and gas temp. Temp promotes increased verlocity. Remember air is less dense at increasing temps. So there are more than one reason to invest. I had my exhaust, turbo and entire dump wrapped for my 12.9 second pass with the stock turbo.

Dean: The car is being tuned tomorrow. The power can't be compared any more as my internals are far from stock=) The turbo will make 240rwkw to 260rwkw at 16psi on an internally stock engine. Maybe more with more boost and adjustable fuel reg.

Yeah, i was just thinking about it keeping heat in... and that's kinda what the turbo's dont like (stock ones at least)

But even if you had 2-3 quick succession runs you could do damage.

I wonder how much extra heat it does keep. Be interesting to find out

    • I think the consensus was that's normal. Sloped road surfaces or something? I remember @silviaz went through this before. It might be one of those things you never notice until you pay attention to it.
    • Im not entirely sure exactly what or where its leaking from, he started to pull the boots to swap to my new tie rods + ends and it just vomited fluid, so he closed em up up, swapped the rod ends to the old rods and let me know so I can figure a solution out, im guessing its all origional as as I passed 103k miles earlier this year im sure its just in need of a full overhual/rebuild anyways.    If i could just yank it off and be good it wouldn't be an issue to ship it out and wait for the turnaround but the guy I work with doesnt really have space to keep my car for a week or two at a time, would rather drop it off and have a replacement ready to drop in
    • What do you mean by "seals"? Internal hydraulic seals (ie, is it leaking PS fluid?) or the rack boots that close the rack onto the tie-rods? Because the former is a rebuild, and the latter is trivial that you or any nearby mechanic could do. Dunno about the cowl. Just buy what you think is required and get anything else you find/break afterwards. Wing? Dunno. Don't like R33s enough to pay attention to them. Mirror glass is just glass (on the surface that you want to polish). Go for it.
    • Hello! Long time lurker, been using the forums to address concerns and questions from afar for a while but I've struggled to find some answers so I guess its about time I made an account and formally asked some more knowledgeable people, since finding local skyline owners is hard (and shops that are knowledgeable or trustworthy to work on 'rare' cars are non existent out where im at, as skylines are quite uncommon to find in the wild around here). So the main 3 questions I have, 1: Steering rack has blown seals, well.. they kind of hold but they are not sealed properly anymore and as my R33 is my DD, i cant exactly rip the rack out and send it off or attempt to fix myself. As most refurb ones are around $1,100 or more shipped, and I have other things I need to work on around the car, I was seeking clarification on whether an S15 rack will more or less bolt right in, and whether a common mechanic could do any other required work to get it to fit. I ask, as I've found a supplier than can sell a manufactured as oem one for around 400, if not I'll likely order a used one from Jacks JDM, and take a risk on the seals there. The second question i have is that im replacing the front wiper cowl and have planned to buy 4 new clips and a new center clip but wasnt sure if there were any other clips that would also need to get replaced while I was at it. Given im sure any that are there now will simply break when I remove the old cowl... Last thing would be a fairly straight forward question, i think. If I manage (strong if, finding one has proven to be a pain) to find a R33 GTR spoiler/wing will it require much modification to bolt to a S2 R33 GTST? I've read the bolt patterns dont match but otherwise would bolt in, only options I have found with much luck is China stuff on ebay and carbonetics, which has a nice $650 shipping fee... so if anyone has any pointers where a US chap could locate one that would be great Random side question as well, the mirrors as I understand are mirror glass, and as im planning to polish my windows from water spots and surface scratches, i was hopeful cerium oxide would be fine for them too, as my research points to, but clarification is always nice. Any pointers would be appreciated, and while I have scoured the internet for answers if I missed a prior post somewhere that may answer these directly please point me towards it, as i must have simply missed it. I have seen a post here or there that has mentioned it, but I usually get 50-50 answers, or half answers... I dont have a lot of fab experience or mechanic experience, outside of hydraulic and pneumatic stuff I did in the military and with how hard it is to source stuff in the US, id rather not wing it and hemmoraghe money lol. Thanks guys! Sorry for the monumental first post haha
    • Yep, there's a very minor drift left that happens a few seconds after letting go of the steering wheel, but not enough to bother me. Enjoying the car still!
