It was the opposite for me, I gained quite a bit of torque, especially in the midrange.


With a stock bottom end, IMO, the compression is a bit too low. I would seriously consider bumping the compression if you choose to pick them up.

Considering i will get a thinner headgasket, minor head job done and flat valves, did u think it will help me somehow? thanks

Thinner gasket and flat bottomed valves can gain you 0.6+ in CR so that will be useful and help you get more out of the cams.

Absolutely. That would make a little bit of difference difference for you.

I have a new build ready for start up soon with Toda C's and I'm using a Power Enterprise belt, with a little extra tension added to keep it from slipping. We will se how it goes, but for sure the belt will be replaced on a yearly basis, cheaper than having to do a rebuild.

i am pretty sure that when you go up to toda b's you should upgrade your valvetrain, (springs and retainers) and also a toda timing belt is recommended. i looked into it for my gsr

Its been well known that due to the great lift and duration of these cams, spec b's and c's have a lot more tension on the timing belt. Its smart to use an upgraded one and increase the tension just slightly.

i fully understand that issue of lift and duration. How about those with skunk2 stage 2 with lift of 12.5 and duration of 264? Those are actually a little higher than spec b but never heard of timing belt recommendation. i just want to make sure...thanks for all ur feedback guys...more pls on the performance of spec for stock comp gsr

The biggest thing is the added compression need to run those cams for the most performance. The higher the compression, the harder to turn over the engine.

Well if you search the archives the Toda cams have a history of beeing hard on timing belts, it's not only because of the increased lift and duration but mostly beacuse of the profile of the cam lobes, the opening of the valves are a lot more aggressive than on stock cams so this puts a lot of stress on the belt. By using a stronger belt. like Toda or Power Enterprise you can add a little extra tension to it to help prevent slipping, but do not expect the belt to last as long as an OEM belt on a stock engine. It is also a lot cheaper to change the belt more frequently than having to do a full rebuild if it snaps or slips. I'm not saying it needs to be changed once a year, but I personally would prefer to be on the safe side after spending big $$ on my engine build.

thanks for all the feedback guys, the only reason i was thinking of toda spec b is because my buddy is selling me his for some decent price and its hard to turn down for the price he offer. Considering that i will need lots of compression to get the most of this, i guess, i will have to start looking for another cams where its less maintenance.

I had a GSR with Toda B's stock compression making 180whp and 131wtq. motor completely stock, even with stock Manifold.


The only problem that I ever encountered with timing belts were non-OEM.... TODA belts. They wore out extremely fast, 20k miles. Now running nothing but OEM belts and no problems.

You gotta be kidding....

Why bump a 3 year old thread with a for sale when there's a for sale thread at the top of the forum.
