Sharpie Posted June 5, 2003 Share Posted June 5, 2003 Hi, I am looking at HKS Cams and Gears and have read a fair bit on here and S/F and have come down to the following: 256in 264ex OR 264in 264ex How lumpy is the idle ? Any other downsides ? i.e. increased lag/spool up Should I go 256/256 ? On the gears, since the stock setting is found to be best, do I really need the gears ? I have a UK TT auto. Any advice, experiences, positives/negatives would be welcomed. Cheers Quote Link to comment Share on other sites More sharing options...
Alex Posted June 5, 2003 Share Posted June 5, 2003 256in and 264ex will keep the idle smooth and is all that is needed on stock turbos...infact AFAIK TerryS does or did have this setup on his single turbo'd Supra. Bigger durations will only push the power band further up the rev range and stunt low down grunt. However.... you have a UK spec car and it maybe more worthwhile spending you pennies on something else that will show a real gain. I would have thought an FMIC would be higher up the purchase list than cams....well I can't remember an FMIC on your car. Quote Link to comment Share on other sites More sharing options...
Roy Posted June 5, 2003 Share Posted June 5, 2003 peter - not sure if this is any help but i have just had the hks 264s both in and out put in last week but am unsure on the gear settings. the one question i can answer is the issue of lumpiness - none! i can barely discern that the cams have been changed. if yu listen really close - there is only an extremely slight difference in the engine tone. there is no real difference is spool time/lag that i a have been aware of.

Sharpie Posted June 5, 2003 Author Share Posted June 5, 2003 Hi Alex, A FMIC will be going on at the same time so, that's the reason about which cams. What about the gears - I read that Terry found that the stock settings were best so, do I really need the HKS Gears ? Bigger durations will only push the power band further up the rev range and stunt low down grunt. Yeah, that's what I read too and prompted the question of 256/256. Roy, Thanks for the feedback, I know that MonkeyM has a Auto with 264/264's in and he mentioned that there was a slight lumpiness to them. Do you find any increase in torque ?

Roy Posted June 5, 2003 Share Posted June 5, 2003 i was on of those that went to france over the last weekend so really gave it some (well as far as i could as the fuelling hasn't been sorted out yet). i detected no loss in low down power (i have been driving it in to work to get a feel) and go through the usual traffic light sprints with beemer drivers (when will they ever learn!). in france, even at *40 leptons, it was still pulling like an express train and just kept on and on, where it would get a bit breathless before.

paulrenn Posted June 5, 2003 Share Posted June 5, 2003 HKS cams are great, but I would avoid using their cam gears, I've had (and so have other people I know) bad experiences with them wearing very rapidly...take the cams but go for some other brand for the adjustable cam gears.

Guest Martin F Posted June 5, 2003 Share Posted June 5, 2003 JUN cam gears seem to be the most respected, due to them using the stock toothed assembly with a different inner section. Quote Link to comment Share on other sites More sharing options...

Guest Terry S Posted June 5, 2003 Share Posted June 5, 2003 You don't really need Cam Gear. There WILL be a rougher idle with cams. Anything bigger than 264 turns the 2JZ-GTE into an interference engine. HKS Cam geare are cr*p. The JUN still uses steel. If you must have cam gear get JUN. If you have HKS keep them covered. They wear VERY fast & have already destroyed 1 belt of mine. Quote Link to comment Share on other sites More sharing options...

Alex Posted June 5, 2003 Share Posted June 5, 2003 The ones to avoid are the AEM ones and possibly the HKS ones. I can't give a definate on the Unauthadox ones, probably worth asking Supraforums instead. But as Martin says the Jun ones are best - I think last time I looked they were £150 each JUN cams offer higher lift on their 256 and 264 varients over HKS...but this will also mean the profile is more aggressive (which can increase wear on the shims Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted June 5, 2003 Share Posted June 5, 2003 Roy, mine were uncovered. Within a year they had worn so they left a sharp edge. This in turn sheared approx. 1/3rd of the teeth off the belt. HKS' answer was that it was my fault for not covering them. Leon still has them on display because we couldn't believe how bad they were. I have another set now which I keep covered ( I was stuck & needed some quick) & they seem OK but I don't use the car much now. Time will tell, but I will get JUN if the go again.

MONKEYmark Posted June 5, 2003 Share Posted June 5, 2003 i have hks 264in 264ex and glad i got them fitted, they are also uncoverd now too. only noticed a slight lumpiness in idle but i like it. always try to find out what if any difference there is when you install new mods. the cams n cam gears seemd to be more revvy. still good off mark on a good surface even though its a jap auto. i was advised to go with 256 256 but thought i would try next ones up. and the 272`s would be too lumpy and read they only for big turbo cars. you loose bottom end and gain top end. was not too fussed for that. the bloke at dragan garage test drove car and said it has a lot of torque (a bit like our GAZ TORQUE ) not too sure what settings they on will have to check.

paulrenn Posted June 6, 2003 Share Posted June 6, 2003 Don't think covering the HKS gears helps, it doesn't, they are made of butter or something...and last probably about a year I had the 272 cams on my Celica, and they were great, if you have programmable ECU you can get a great idle, very streetable in my opinion...I don't really agree with going for 'mild' cams, if you are going to all the expense of changing them in the first place. But that's just me If anyone from HKS is reading this thread, love your cams guys Quote Link to comment Share on other sites More sharing options...
Roy Posted June 6, 2003 Share Posted June 6, 2003 mark - when you find out the settings - would you please let me know as i am running similar cams but mine doesn't seem to be lumpy at all - wondering if my settings may need adjusting. ta.
