ive gt a b16a eg engine with b16b pistons shaved head ported double springs.. type r on the intake and i just switched the intake side of the b16a to the exhaust side ,itr intake manifold and spoon ecu.. an im running on ctr cams.. i was wondering if i could run a ets say a toda spec b cams will it make power? or loose power? cause some of mah friends say that spec b and c toda's are only for stroked engine.. pls help me.. or if you have a better suggestion on what higer profile cam i can use tanx.. about the skunk2.. which is meatier the toda b or the skunk2 stage2?

 

i know the answer but i wont answer it becasue only katman knows.

 

well if you know anytrhing man maybe can u spare your s cents on this??tanx

 

1. the toda b's need stiffer valve springs than type r's.
2. the toda b's will make power just are hard to tune out the intake valve overlap
3. they were not made for stroker motors. but with your set-up (sepending on how much you have milled the head) you might have to worry about piston to valve clearance.
4.Skunk 2 11.58 mm, duration 252 @ 1mm 10.9 mm, duration 249 @ 1mm
Toda Spec B 12 mm,duration - 255 @ 1mm 12 mm, duration - 245 @ 1mm

 

my cylinder head is milled 1mm.. quite a lot eh..damn more help peeps.. so damn the toda b's better? some more info man.. do i need to change mah current springs if im goin toda? or the skunk?

 

yes you should go with the appropriate valve springs of the manufactures spec. both skunks and todas have the appropriate valve train with the kit.
you will have no piston to valve clearance problems with only .020milling. and there is no way your head is milled 1mm your timing belt would not fit.

 

well the previous owner of the engine told me that its 1mm.. but how far can u go with milling the cylinder head? ...for my setup which is better ? the skunk2 or the toda b's?

 

nah man every.02 is .2 compression he was dumb.

 

oh damn.. umm so .. what you think about the cam? should i go with the skunk2 o the toda b's???

 

well what racing do you do the toda b's pwn3d for roda racing. they are good mid range cams and iam not sure on the skunks2 not sure. my aim is rainforestEF8

 

i dp drag man tanx man...

 

up u go.. hey katman pls.. help me out on this...

 

.040" = 1mm. Heads can be milled more than 1mm and the timing belt still tensions properly.

 

yo t tanx for the help tanx very much!! chill bro'

 

any particular reason why katman needs to help you?

you do know there's quite a few people around here with superior knowledge don't you? just cuz kat is a jdm geek doesn't mean he knows everything..

sorry.. i couldn't help myself..

 

crower3's. BUT, .040 is alot man....trubble w/ high lift long duration possibly.

dude i have had assloads of problems with a h22a with a .040 milled head i could hardly get the belt to stay on.

 

oh im sorry peeps if i ffended some of you.. but.. katman is the only jdm personality i knnow.. well cause of tiiite boyee racing and ff squad.. well hes kinda my idol.. hehe anyway can u guys help me out then?? plss..

 

UP BOY...

 

up boy.. hey katman yoohoo....

 

hey rainforest, did you have to modify your auto tensioner?

 

up u go..

 

but I am the greatest, aren't I? fly like a turd, stink like some pee?? hehe..

Spoonskiee..
Rainforest basically layed it all out for you...

I am a bit baffled as to why you had your head milled AND you're using CTR pistons? The ctr pistons alone, should bump up your compression high enough, without a head mill....that is, unless, you had this head before you put the CTR pistons in. The compression CTR pistons + a B16A engine is still fine for daily driving/weekend racing purposes.

As far as camshafts go...
I have little experience with any of the Toda camshaft line-up. I mainly go by the info people have posted here who have tested and tuned these cams such as Mike K and a few others.

I do have knowledeable experience with these cams though:
- Skunk2 Stage 1 camshafts
- Spoon camshafts
- R cam shafts

For the Skunk2 stage2's, I was told from a wittle bwerdy in da twee, that you can run stock OUTTER springs + Portflow inner valvesprings, and those would suffice for the Stage2's. Or you can just use the full blown Skunk2 valvespring set. Tuning and powerwise I haven't heard much about them yet.... but I haven't heard anything bad about them either. They're still pretty new.


You said somthing about using Toda C's? hah..yer crazy if you plan on using those for daily driving. Those are straight up "race-only" cams from what I've come upon...you don't want those if you plan on daily driving. Also, you have to take valve-to-piston issues that arise with large lift cam profiles and having a milled head.

Someone needs to do a big ol' camshaft dyno test, just like that header test a few months back...

A possible suggestion for you..
if you want to have higher compression than the CTR pistons in a B16A+B16A head allow, you might want switch over to a GSR/P72 head, have that ported but NOT MILLED and run Toda B's with that one your CTR piston'd B16A block...

The outcome using a GSR/P72 head on you current block will be this:
1) You'll have even more compression on top of what you have with your current milled b16a head.

2) you won't have to worry about valve-piston contact since the GSR head will remain UNMILLED, aaand, as an added bonus, you won't have to worry about correcting the cam-timing, like would on a milled head.

3)than you have now with your slightly milled B16A head, yet retain the stock unmilled traits of an unmilled head. You

4) you'll still have to upgrade the valvesprings to whichever you plan to go with, providing you know what camshaft you ultimately plan to use/go with.

5)oh yeah, you'll wanna swoop up a Skunk2 intake manifold for GSR head as well to keep the Type-R like breathing habits intact.

yo tanx me idol katma.. cooldude.. i gt the head already milled befors the r slugs .. ..so can i run the skunk2 stage 2's on mah engine? i tthink its a bit safer compared to the lift of the toda b's i think the b's have a tad much higher lift the the skunk2 2's... watcha think???
