Yes, using stock 34R dumps.

Mods are:

-7's, stock dumps with 60mm into 70mm front pipe, metal cat, apexi N1 exhaust. Apexi Power FC and HKS EVC 6

The workshops that have tuned mine are in Southern Sydney. Hint, Levinboy has seen my R in the same workshop he uses. But that's not who tuned it this time round.

Would I be better off with dialing in cam gears on stock cams?

My goal is for 300kw's. But 'street' responsive.

Oh I can't see that cause on mobile

I'm to am on phone, iFail 5 lol

At the bottom of the page under the advertising thing is a little box with a line out the bottom, push that and all will become clear :D

That is exactly what I had, 313rwkw in a quite responsive package and then bam bent and cracked crank :(

Do the cam gears

For the love of god... Just buy the UE cams.. They are going to be better then any of the other stuff you will buy off the shelf

I already sent an email to UE ;)

Needing stronger spring is cool with me, I wanted to replace them already

Ask them to do the complete cam, spring and retainer combo. It all works. It's bloody painful when it doesn't...

*mumbles under breath..."lame jap shit"* lol.

I find it interesting that people are going into so much detail into choosing/designing (!?) cams here yet the high lift UE 250 cams are being recommended as a blanket rule for 2.6, 2.8, 2.9 and 3litre engines - dynamically cylinder filling/trapping between all of those engines are going to be quite different. I've chatted about this with XKLABA and Piggaz before but it still seems to be being overlooked, not sure if I am missing something with the design here or if you guys have found that they are a magic bullet regardless of compression, turbo combination, piston versus valve location etc?

The results are very good, and achieve what has been expected - but there are lots of really good results out there, I guess it's impractical to do a test but I'd love to see the 250s compared with other cam options on like spec motors and see if the results are all as expected. I like to think there is always a better way :D

I'm going to try the drop in poncams type A.

Probably too small for my engine but I compared them to supra 2JZ factory cams which is a little closer to what a stroker is and I'm going to see what they do. I also got cam gears in case. If I decide these are too small I will spend much much more and go with real cams later. Does anyone know how much I need to relieve the head for the cams while I'm porting it for the larger cams later down the road?

Lifters, springs, retainers and "Pro" cams came out to somewhere around $1500 US. This is before nailing down shim height and ordering correct shims.

I'm not sure by what you mean to small for a stroker, my 3.0ltr has 250 x 9.15 poncams with GT-RS twin turbos and with 28psi made 623hp at all for

As for relief for cam lobes, it really should be done to suit cam which would mean you red to get cam and then see what needs removing

I'm going to try the drop in poncams type A.

Buyer beware: There is currently a supply issue with Tomei cams..

I recently had a lubrication issue with my motor that saw quite bad damage to my Tomei sticks. I replaced every relatable part and really struggled to get another pair of Tomeis, which is when I found out about this apparent supply issue from multiple stockists. No names, but most of the big local guys are talking about removing them from shelf as they are too hard to get ATM. I was told there was a 5 month wait to get the ones I purchased and they could only supply 2 pairs. They did however sneakily send out a lot of left overs from a custom order in place of both 256 and 264s and many stockists were simply selling them on.

Moving on from this, the brand new lifters I installed turned out to be faulty and failed within an hours use. I drove the car home on the noisy lifters and opened the motor to find that the brand new cams had copped pretty bad wear already (just from noisy lifters). I've never seen damage that bad from noisy lifters, its shocking and cries out to me that their little 'supply issue' is not so much related to demand as it is to quality.

I just thought I would chime in with a warning as I am down a set of cams and am unsure what to make of it. Will most likely be going another brand and forking out for the touch up tune as a result.

do you mean we shouldn't buy tomei cams because of bad quality controls on their lifter or because they might not have them in stock ?

what spec are your camshaft?

Orly?

I mean, yes - correct... just testing :)

I wasn't aware of UE before this thread, their website is under construction and on their facebook page , all recents post are about american big build. so it must be the reason why not everyone knows about these cams.

However, I had a facebook conversation with them and all they offered me was some tomei or mine's camshaft, nothing custom here.

and when I asked them about the complete kit, as per piggaz 's recommandation. they never replied to my message. Either I don't have the right shop, they dont make custom camshaft anymore or they think I'm not a serious buyer..

Are you talking about the Tomei +1.0mm lifters/buckets

Sorry about the confusing babble guys. The lifters were not a tomei product, they were an aftermarket replacement sold as a upgrade for SR20s (upgrade my ass).

The lifters are to blame for my second failure however I would have really thought the cams would survive some noisy lifters for the drive home. Never have I seen a set of cams get flat spotted from noisy lifters.. And I have heard some horrible lifters.

My cams are Tomei 256 Type R for S13 SR20DET.

This report/warning is made on the basis of the coincidental 'supply issue' and a pair of cams not durable enough to cop < 1hr use with noisy lifters. I do believe they should be more durable than this.

I hope that clears it up.

Yeah they are just cast.

I used Penrite HPR5 which is a 'full zinc' oil which is whats required for proper camshaft run in. I ran the motor for a good 30 minutes with varying RPM before cool down and then restart. By my knowledge thats the right way to do it, however slightly less pedantic.

Anyhows, thats the report and my personal opinion based warning. I am just guessing here but I have heard talks that Japan has had materials shortages due to shipping issues post tsunami. Now its also been speculated that these parts are made elsehwere in the world but this is the general gist of what I am starting to form.

Not wanting to fear monger anyone but I am definitely keen to change to an American supplier. Despite the fact they would be made in China products I am more confident in the QA requirements set out by the brand. Thems the feels anyway.

CobrAA. It is pretty clear, by reading the posts in this thread, that UE is Unigroup Engineering, here in Australia, not in some mystery location on the other side of the world.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
