Eibach springs and retainers combo

Eibach does not make retainers.

 

[k20coupe]

yes they do that's what ips uses in their head package

 

[neo]

Sorry, those are not Eibach retainers.

 

[k20coupe]

So what are they?

So what are they?

They were IPS spec to my knowledge. If you are looking for retainers for the Eibach springs, Tom @ PortFlow is your best - if not only choice.

 

[ampmstation247]

With the mods you have listed you should be able to make 250whp without a problem if you have a decent tuner.

 

[k20coupe]

he's decent I'll be happy with 230 the extra 20 are just a plus well I got the retainers that they sell since they came in the box with the springs I guessed they were eibach also

I didnt know Eibach sold ti retainers. I received my evs about a week or two ago and they did not offer retainers with them.

I went with portflow retainers for the evs.

I have a pretty similar set up and am looking for 250+

you should hit your mark no problem with a decent tune.

 

[allmotamak]

you should make 250whp now problem i made 240whp with

stock block k20z1
rbc intake
bc stg 2 cams,springs and retainers
dtr 4-1 header
front mount velocity stack

good luck on your build

Since you're going up to 88mm, go a hair higher on compression, like 12.1. And get IPS markIII k2's. Ditch the copy header and go for something nicer. Its worth it.

 

[k20coupe]

will a thinner headgasket give me that extra .04

Are u almost done with ur build

 

[k20addict]

you should make 240-260 as long as your compression and leak down is very good

 

[k20coupe]

so the header will hurt me more than help me

 

[thirdlobe]

The springs and retainers went on the head today. All I am missing are my bearings - these should be in on Monday.

so the header will hurt me more than help me

yes sir - try looking for a used rcrew or something. that maybe the best bang for the buck.

 

[k20coupe]

I saw a couple of threads about this header and it seems its not that bad but if I find a R-crew for that price it will be a good buy

same thing i was about to say , its easy to make 240ish on a stock k if i put anything in my motor i better get 300+ or its a waste of money

 

[MANNYMAN]

thats a no... will not get u from 11.7 to 12.1 with thinner HG
hope u havnt gotten the pistons yet.
and i have seen RCREW header sell for cheap on here.. like 400 shipped range.
I have RCREW and pretty nice over all. Should be intresting on what numbers you make.
