I'm planning on buying some larger cams with in the next few month for my LS-VTEC. I've have P73-AO piston (USDM ITR) and read that you can't go with to large of a cam. Was wondering if anyone know the accual size of the cams that would be at the limits. I'm interested in EF-1's (EF-1.com) mostly the M23 I know the lift is 12.1mm forgot the duration (at work and its block??) but rocket also has some M20 or M21's which are 11.6mm which one will not have clearance issues with piston to valves??? TIA

 

well if im not mistaken the ITR pistons in a LSvtec yeild a 11ish :1 compression? id check out some skunk stage 1's or something of the like

 

So there about 11.6 mm of lift right.....I trust rockets cams more then I would sk2. I'm getting the EF-1 no matter just need to know which ones I can get by with on lift/duration

 

PM rocket...

 

I probably just go with a set of Type R's
They are cheap, and will provide a decent bang for buck without serious tuning.
Anything more than a stage one requires cam gears and a lot of time / money.
Plus crazy cams are like 3 times the price of type r's. You could have 6 crazy party weekends for the cost in difference between Type R cams and even like a stage one cam.

 

yeah guess gonna have to i/m rocket about them. If I get M20 regrinds there only 300.00 and 50.00 core then the M24 are around 700.00 for new blanks. Price compared to anything else is really reasonable. And his GTD can't be beat. 100% cust satisfaction is always the best option
