i live in jamaica an own a evo 5 gsr. i blue the original engine but was lucky to get a brand new balanced and blue printed from a racing team in japan that were supplied by ralliart japan.the turbo was also balanced but all the internals are stock.i recently put a set of hks264 cams with springs in but noticed no improvement in the car performance.can anybody tell me why.

 

[Guest]

did you also fit the adjustable cam wheels ?
i belive the cams are timed differently to get any gains
did you not get any settings with the cams ??

 

[Guest]

There are different profile cams that you can get, normally uprated cams like HKS cams are designed to increase mid and high rev response. Check if your car is faster say in third gear accelerating from 4000 rpms.

That's funny. I also live in Jamaica. I have an Evo I and noticed a big difference with the 264 cams. You should compare the specs of the original cams with the HKS cams. It is possible that the cams in the V are already very similar to the HKS 264s.

hi moulton, i did,nt get the adjustable timing gears.i have seen many modified evo,s from 1-6 in jamaica all with cams,but none with timing gears. i suspect that dialing in the cams needs a certain amount af expertise.we don,t have a 4 wheel rolling road in jamaica so tuning is a little more difficult.
apparently the full hks kit comes with cams timing gears and something called shims.does anybody know anything about these shims. how important are they in maximising the full potential of the cams and how do you what size shim to use? looking forward to you experts reply,

 

[Guest]

shims ????
kit should include valve springs and retainer caps

 

[Guest]

hi moulton,
what are retainer caps,and what do they do?

 

[Guest]

valve spring caps,to go with the hks springs
you need to speak to EVOBOY !
he is a walking workshop manual when it comes to tuning !

 

[Guest]

After heavy modifications a acquaintance dialled in some intake advance and after testing admitted that the car was beginning to scare him. Reported huge gains in top end power.

If you have gone to the trouble of fitting cams, adjustable pulleys seem a logical option.

 

[Guest]

i have tried inlet advance and ex retard,with standard cams
the timing is now back on standard !

 

[Guest]

What happened?

 

[Guest]

hi braf,
you are probablt right about the adjustable timing gears. the only problem is there are no 4 wheel rolling roads in jamaica so dialling them in could be a problem,and i don,t know if its worth the effort,money and risk.one thing i can tell you is everytime somebody spends money upgrading their engine they always claim the car is running like a bat out of hell.
in most cases the car is running the same or even worst than before the modification and all the gains take place in their minds. i am not saying this has happened to your friend,howevere this is the reason i appreciate discussing the issue before parting with anymore cash.
can somebody contact EVOBOY for me so that i can get his expert opinion on the subject.

In my experience HKS 264 cams do not need uprated valve springs.

As I said before the spec on your stock cams is probably similar to the HKS 264s. Looking in the Hyper-Rev book for Evos 1 - 5, HKS don't even advertise these cams as being for the 4-5, probably because they are not suitable for making power. This is just speculation on my part all the same.

Laurence,
I've never been up theere myself, but Junior Lowe in Mandeville jacks up the back end of AWD cars and runs them on his 2WD Dynojet. It probably won't give accurate numbers, but will give repeatable results i.e. it will show the effects of cam changes and cam timing changes. Who is working on your car anyway?

 

[Guest]

Laurence,

Grab yourself a G-Tech. Not glamorous but you can use it on a long quiet stretch of road to access changes. Bit of a pain but it will work. Amongst other information it will let you know what kind of G’s you are pulling.

hi wreckleford,
what is the hyper-rev book. what,s in it?. you can mail me at [email protected]

 

[Guest]

I'll mail you soon. For the time being, Hyper-Rev is a series of Japanese books on all sorts of Japanese parts. I think they are actually moslty made up of compiled magazine articles from Hyper-Rev magazine. Anyway, it is filled with photos of parts for the Evos as well as modified Evos 1 -5 from the Japanese tuners. Of course it is mostly in Japanese with a few English words here and there. You can figure out a little bit. I have spent hpours just looking at the pics. and getting ideas for my car.

 

[Guest]

Hi!

Do you know where I can get the hyper rev books and the lancer evo magazines for the evo v and vi?
Do you have some pictures scanned from them?

 

[Guest]

hi wreckford,
i borrowed a hyper rev book from elvis. you were right as they only advertise hks cam for the 1-3 evos.
maxi, apparently the only way to get hold of one of these books, is have it sent from japan. the only draw back in that everything is in japanese.

 

[Guest]

You can get them in the U.S. also, from Japanese specialist book stores, the type that sell Manga etc. That is here I got mine from, a friend brought it for me. If there are Japanese book stores in Europe you could try them.
