hi guys;

here are my setup:

98 Spec JDM ITR Block (stock)
97 USDM GSR Head (Ported and Polished by Portflow)
Mugen 2-layer head gasket
Supertech High Compression Flat face valves (standard size)
Toda Valve springs
Toda Retainers
Toda Cam Gears
Buddy Club Stage4 Cams


a few questions:
1. will this setup too dangersou that i'll run smack a valve?
2. toda valve springs will hold up the bc4 cams without problem right?

any other info and suggestions are welcomed, thanks!

 

it should be ok...im assuming your runnig itr pistons?

 

Search user name GUILOTINE, he had similar setup.

 

What header are you using?

 

smsp

 

Damn, yeah you're gonna make some power

 

bump for more info.


thx clean rice, i hope for more power too!

 

waste of time and money... keep your itr cams in for the 1.8L, keep the stock ITR intake arm, with an air box/comptech/mugen style induction. And then tune.

yes, i'll have the car tuned, i just want to get everything ready first

 

also, if the head needs new valve guides, are all b-series valve guides are the same? as in b18 and b16 heads, thx!

 

if you get new valve guides just buy oem ones and i'd probably let the people that are gonna install them buy them too... btw don't go bronze they were down too quick (assuming this is a daily)...

 

thanks for the tip! what material are oem valve guides?

 

Yoorang, where did you find that Toda makes retainers? I've never seen Toda retainers before...

You don't have to worry about smacking a valve. You're still only looking at around 11.5:1 compression. That should be fine for the BC IV's.
I love the BC IV's!

i forgot who i spoke with over the phone last year while searching for retainers to go with my toda valvesprings, but those toda retainers were released last last year. http://www.jhpusa.com is just one of the place that's selling them.

thanks bro! the jdm itr have a 11.1 default, switching over the gsr head help me gain that 0.2, and the flat face is average 0.3 - 0.5 compression gain.... my worry is this compression might be too much on a 93 octane gas. will have it tune by hondata or neptune

 

If you replace the valve guides you are going to need a new valve job done as well.

 

yes, all these were replaced, and done. complete head work done and inspected by justice race engine.

I don't foresee a problem here. You're probably closer to 11.5:1 compression which you could PROBABLY get away with on 89 w/ good tuning. 91 here shouldn't be an issue.

 

thanks man, i'm just concern w/ today's gas, it's just not as good as it was before.
