I see the kits on e-bay for valve springs retainers and valves that are safe to 11000 rpms. My question is what else would you need to go to 11,000 rpms? It really doesn't sound too good for the engine. I assume you would want new cams at least. Let me know what you think.

You need cams that make power past 8,200 to go along with that..
Thats just to start.

 

Like droppedcrxsi mentioned, aftermarket cams would be needed to realize good power after around 8,200rpm plus you would need to reprogram your ecu for the higher rpm, and i would consider doing a set of better rods and rod bolts so not to throw one which i've seen happen before.

 

Basically rebuild your whole engine, and up the compression (a lot) if you really want to rev that high.

agreed

 

If that is possible That would rule! Just for the sound.

 

about that kit, I would be skeptical if it is not a known and trusted company.

Not to venture OT but..... I'm looking to hit 11k'ish My motor is not done yet but here's the setup.

B20 block
B16 head full p&p
eagle rods
JE 11.5:1 pistons
Toda spec C cams
Ferrea valves
Ferrea valve springs
Ferrea retainers
ITB's
GReddy 4-2-1 one piece header

 

You're going to run a relatively stock B20 short block to 11k?
Is this just a ONE TIME thing or are you planning to do this often?

I don't plan on driving around town at 11k if thats what you mean. But if you are planning on knocking the B20 then you can stop now cause I've heard it all before. Everyone thinks the B20 is weak because of it's "siamese sleeve" design, but that is untrue. I am not running boost, so new bearings and a good honing will be sufficient. Plus the motor had about 9k on it when I got it.

 

Hmmm, I wonder how high my motor will rev to with all my work and still be making power

D16A6 Head:

Milled.040
3 angle valve job
port n polish
ferrerra retainers
1mm oversize titanium valves
dual titanium springs
Delta 272 cam

Sohc ZC block:
Arias 11.5:1 compresion pistons
Eagle Forged rods
Balanced and micropolished crank
Stock bore

3 layer haeadgasket

I think Ill have about 12.0-12.3:1 compression

Havent decided on intake or exhaust mani or w ay to manage it

AND ONTOP OF THAT

NITROUS!!!!!!

WHEW, this Crx is gonna fly

 

can someone explain differnece between aluminuim and titanium retainers ? wear rate/strength/reving capabilities etc

also, what would i need to rev b16a2 to 9500 now again on daily driver , already have followimng waitin to go in

jun 3
oem std bore ctr pistons
ecu management
(undecided on which retainers/springs to go for)
gonna use oem headgasket
unsure if i should go for valves

 

im gonna buy set of portflow springs/retainers. anyone got any bad things to say about them ?
