Im just about to drop in some tomei poncams 8.5mm lift into my rb25det and was contemplating doing the valve springs while ive already taken the cams out.

I was looking at the tomei type a valve springs 8.8mm lift , are these the correct ones I need?

Yep get Performance Springs.

I got a set in mine and they were a great price :blink:

You taking the head off to do the springs? (I did)

I looked on there site , which ones do I need cause its not model specific? and no Im going to do it with the head on and just pressurize the cylinder to hold them up.

The Performance springs is just little bit stronger then standard. The supertech springs are probably the best you can get at this stage. Those are stronger then the type B Tomei springs which are cheaper as well.

Totally agree. I lost one engine and broke valve springs in another with performance springs. If your aim is big hp the supertech is a much better option.

He is only after a 280-300rwkw setup it think so not huge HP/Boost given a stocker motor.

You're probably right Ash. they are an upgrade but if big hp is the goal I would choose other brands.

I am not the only one i know of to have probs with those springs in high hp situ's.

      Definitely a hearty eater when we go out, I consider these meals my cheat day as I've been watching my calories in and calories out pretty hard since my little fun size stroke, I've gone from a fat boy of 89 Kg, I'm only 165cm tall/short, down to a almost semi lean 73 Kg over the last few years, I'm currently around 17% body fat which my doctor is very happy with, but, my goal is to slowly get down to and maintain 15%,so yeah, I want all of the protein, carbs, fats and sugars when I go out for a binge

      There was a great one on Victoria Rd in Gladesville too back in the day. I can only assume GTSBoy is thinking of the mill up on the wollondilly, no restaurant there any more but they have restored the original steam engine on site and run it every few months, have an annual steampunk festival etc @The Bogan, you came to the wrong town for restaurants. we have a few reasonable asian and indian options but the Paragon is as good as it gets otherwise. That brewery is apparently just opened, been meaning to give it a go some time. The Highlands have plenty of fancy options but I suspect you are more a hearty eater than fancy eater

      Going by the intake & injectors I'd be guessing it's a DE, check the head casting number, should be 5L8 on a DET, 5L7 I think is the DE number.
