I have been running the HKS 274/278 cams for over 2 years and got a little bored of it :-)
Hearing a lot of praise for the Tomei procam 270 (lash type) over the net and locally, decided to try it this week. Weather have been more or less consistent over last 7-10 days (horribly hot), this is a pretty good comparison i think.
HKS wins this hands down in my opinion cause:
- Better vaccum at idle (HKS -18i nHg vs Tomei -14inHg)
- Part throttle response for HKS is much better in my opinion
- No real gains at the top to justify the cost and the low vacuum at idle making cold start and slow driving a tad bit difficult
To be honest though, I'm used to stock cam like drivability and start with the HKS. Compared to other cars with 11.5mm lift cams, Tomei drives much better i think.
Will be trying the GSC S1 next week as I have it in stock and S2 in the next 3-4 months (getting stuff in my country from the US is a real pain...)
Please share your opinions / predictions on the S1 and S2 down the road :-)
I'd imagine the S1's aren't nearly enough cam for a 2.4. I'd think the R2 would probably be a good fit for your setup as its intended for stroker setups with lower rpm limits.
The new Kelford 272R also looks like a very versatile design and in their own testing video it outperformed the S2's (objectivity and test conditions open for debate)

The Kelford 272r is between and S2 and an R2, closer to an R2.
Thanks for chiming in guys. The roads in my country is usually full of traffic and mid band is very important for my setup. So, i'm trying to find the best balance between solid mid-band power and optimum top end where the car doesn't fall on its face post 7,000 RPM. If I have to settle for a trade off, I guess i'd go for more mid-band torque.
Kelford 272R looks like a solid cam but I think it will shift the power-band further to the right. I might be wrong though as I have no experience with that cam.
The Tomei procam has a 11.5mm lift and I think this is the max I can go without losing too much below 4,000 RPM.
On a side note, did some further experiments today with the Tomei by taking off my hi-flow CAT and putting in a resonated test pipe. It looks like the CAT did have some restrictions after all :-)
So, after a weeks tuning of getting the fuel delivery right, was able to get a few more ponies from the Tomei cams. Looks like it's a keeper now vs HKS. The S2 should arrive in the 2nd week of September and should be an interesting comparison.
My Mivec cam gear is toast :-(. Was getting weird 10:0:1 AFR after couple of WOT's and was puzzled since yesterday to find out the reason. Logging Mivec today revealed the culprit. Good thing is that I still have my original Mivec cam gear which will be installed tomorrow. Hoping to share the toast Mivec internals soon to try and figure out what went wrong.
Would be interesting to drop-in HKS to see how they respond to less restriction in the exhaust, chances are they would re-establish their slightly midrange advantage, while providing for smoother idle and generally OEM like manners.
Solved the Mivec problem after working on it for 2 days. It turned out to be the cam bearing cap (closest to the Mivec gear) leaking oil resulting in loss in pressure for the Mivec system. This was resulting in Mivec cam not advancing after 2-3 pulls and AFR going pig rich (10:1). Interestingly, Mitsu doesn't sell these bearing caps separately from the head. Evo X has separate replaceable bearing which can be ordered.
Sharing screenshot of logs below for troubleshooting reference:
Faulty Mivec
Aoto Rebellion took pictures of some local Evo's here in Bangladesh (including mine) the other day in our workshop. Thought I'd share it here as they came out real nice :-)
Finally winter is slowly coming to Bangladesh. Temps are around 80F now :-)
I'm back to Tomei Cams. In my experience between the Tomei; GSC S2 & the HKS 272/278, Tomei has the best overall performance. It idles close to stock and has a shining top end without giving up too much in the mid band.
Also, installed MAF last week to do some experiments with the tune and found something very interesting. Even on a relatively small turbo: Blouch 2.0xtr (BBK 3B) and 2.4LR block, the MAF is too restrictive. MAF vs SD....96F intake temp.
