Hey All I am in the process of replacing the springs is an RB25DE head with RB26 springs and need to know the right way of doing it. cams are out and the lifters have been removed.

would anyone be kind enough of to explain step by step what is the correct way of replacing the springs.

Thanks

remove spark plug and run some compressed air into cylinder to keep valves up (most of the time the valve stem seal is enough to hold the valve in place) if you don't have compressed air you can always wind the piston upto top dead on the cylinder you removing just incase the valve drops.

I take it you don't have a valve spring compressor so.... you're going to need:

A mate

2x Big flat head screwdrivers

a pen magnet or something you can poke in to get the collets out

and last but not least poke your tongue out at just the right angle whilst pushing the 2 big screwdrivers down on the outside of the spring seat while your bud grabs the valve collets with the magnet and wallah should be able to swap em over.

I usually plug oil return drains just incase things don't go to plan.

Goodluck and cheers

Matt.

I should have given a bit more info..

the head is off the car and I will be using a "C" spring compressor that goes around the head and holds the valve still.

its cool i have talked to an engine builder and have the info i need. Thanks!

Just bear in mind that many c-type spring compressors wont fit a rb-- head, as they are designed for old school heads. See if you can use one down at the local head shop(or get them to do it), there are pneumatic ones that will change all 24 in about 15mins.

you can get a little tool that fits in the end of the c spring compressor and will fit inside the cavity where the bucket sits.

The screwdriver method really does work, multivalve heads have a much lower spring rate than old school two valve heads.

horses for courses.

      There are advantages, and disadvantages to remapping the factory.   The factory runs billions of different maps, to account for sooooo many variables, especially when you bring in things like constantly variable cams etc. By remapping all those maps appropriately, you can get the car to drive so damn nicely, and very much so like it does from the factory. This means it can utilise a LOT of weird things in the maps, to alter how it drives in situations like cruise on a freeway, and how that will get your fuel economy right down.   I haven't seen an aftermarket ECU that truly has THAT MANY adjustable parameters. EG, the VAG ECUs are somewhere around 2,000 different tables for it to work out what to do at any one point in time. So for a vehicle being daily driven etc, I see this as a great advantage, but it does mean spending a bit more time, and with a tuner who really knows that ECU.   On the flip side, an aftermarket ECU, in something like a weekender, or a proper race car, torque based tuning IMO doesn't make that much sense. In those scenarios you're not out there hunting down stuff like "the best way to minimise fuel usage at minor power so that we can go from 8L/100km to 7.3L/100km. You're more worried about it being ready to make as much freaking power as possible when you step back on the loud pedal as you come out of turn 2, not waiting the extra 100ms for all the cams to adjust etc. So in this scenario, realistically you tune the motor to make power, based on the load. People will then play with things like throttle response, and drive by wire mapping to get it more "driveable".   Funnily enough, I was watching something Finnegans Garage, and he has a huge blown Hemi in a 9 second 1955 Chev that is road registered. To make it more driveable on the road recently, they started testing blocking up the intake with kids footballs, to effectively reduce air flow when they're on the road, and make the throttle less touchy and more driveable. Plus some other weird shit the yankee aftermarket ECUs do. Made me think of Kinks R34...

      Return flow cooler will be killing you I reckon. You can certainly push more through a low mount setup but they're good numbers for a stock looking engine bay.  Mine made 345rwkw (hub) at 22psi on 98 with a "highflow" on a stock manifold but it's a long way from a normal high flow or standard engine. I used one of those Turbosmart IWG-75's and it was great with the Motec running closed loop boost with pressure being applied to both sides of the diaphragm.
