Prelude Type S Cams...Which Valve Springs??? - Honda Prelude Forum

precisionelite · 08-15-2005, 01:56 PM

I'm planning on running prelude type s cams in my 01 lude. My question is: What valvesprings/retainers should I use? At first I thought about skunk2 or crower. Then I read that you should use the valvesprings meant for the cams or the harmonics could wreck the valvetrain. I know inlinefour.com sells Prelude Type S valvesprings, i'm thinking that would be the ideal. Could I just use my stock retainers, i'm not planning on revving it past 8k. My racing shifts are all at 7500-7600.
I know a lot of you guys out there think that the type s cams arn't worth it. I'm going this route for 2 reasons. 1. I don't want to deal w/cam breakage i've seen to much **** w/crower and skunk two. 2. I want to keep it as oem as possible.

P.S. i'm planning on the type s pistons as well.

wish I had the loot to put in Type S pistons...I need them bad my rings are going....I haven';t heard that much of Skunk 2 cams breaking at all, thats why I got them..i love the gains also..keep in mind Skunk 2 grids their cams from OEM cam blanks! with 11:1 compression ohhhhh nice and a good set of cams your set..

I would stick with the same brand valvetrain and cams....

y mod if u want to keep it OEM spec? just drop a whole type S clip in there then sell ur current motor... LSD,cams,pistons,euro r manfold... after said n done in the long run you prolly still make out better then payin staight labor...if current motor is semi low mileage n in good cond. might as well swap it out n sell it n get some $$ back...

Hey Nuke,
What is the powerband of the Skunk2 stage 2's?

nuke79 · 08-15-2005, 07:43 PM

haven't experienced the full range yet cause I;m only revving to stock fuel cut, 7650. but they want to pull, VTEC is way louder and stronger, only after me tuning with VAFC and wideband.....saving for Hondata s200 w/p72 then will be able to open them to 8500. sux cause now my car won't start today...LOL!! need to figure that out first

JaXx4k · 08-15-2005, 08:23 PM

^^ i got s200b w/hondata chipped P28 if ur interested...

PM me do you have conversion harness also...?

precisionelite · 08-16-2005, 08:37 AM

don't make the same mistake i did nuke79 there are 2 different types of conversion harnesses. Obd2a and obd2b make sure you get the right one. www.hondata.com has a great wizard that shows you.

Is it safe to rev to 8500 w/a stock bottom end?

There are type s valve springs on sale on ebay right now.

"Up for sale is a set of Prelude Type S intake valve springs. These springs are lightly used and come from a 2001 Honda Prelude Type S from Japan. They still have the yellow paint on them from the factory. You can tell these are Type S because of the square shaped material used to make the outer valve spring. This set contains both inner and outer springs, but there is one inner spring missing. I don't know where it is. You can use your OEM Prelude inner springs with these outer springs. I checked the spring pressure on a machine and its the same for both the Type S and OEM inner springs. Please check out my other items as I have LOTS of other H series and F series Honda parts for sale. I have the Type S Exhaust springs on another auction."

Does anyone know if this is true...that the type s inner spring and the usdm inner spring have the same pressure?

OBD2a, thanks precisionelite, I'm not going to be revving that high all the time just want to know I can, and stay in the higher powerband when shifting when needed. When I put type S pistons in down the road I'll go with lightened rods just to make sure everything is cossy, and most def not without tuning..but I guess I'll know what my cams can really do in the upper range when I get to the dyno after my header gets here...(hopefully will be able to get engine management by then or nothing past 7650

What gen do you have? It looked like mine hit rev limit at 7900 stock. I have a 5th gen.

nuke79 · 08-16-2005, 08:44 PM

5th gen ....stock tach is off, by about 300rpms I shift at 8k and is about 7650 on the VAFC.

JaXx4k · 08-16-2005, 11:54 PM

^^ your 97 base should fit the hardness i have i own a 98 base i bought everything from hondata so it shouldnt be a problem from a lude to a lude

=D

Rev limiter kicks in @ 8 on mine... SS power

I usually run 1st into 8grand so I can catch vtec in 2nd gear
