Yea but I wanted to see how responsive I could get it, would have destroyed most twins ???

How soon will the EFR be going on? Next weekend? :D. You'll have to plumb those gates in but that won't be hard.

So does anyone know a 7670 result out there that makes it a no brainer decision? I have spent this morning again cruising google and can only find one old article which supports what i was saying about the SR20 comparison.

I did see some good results on a std EVO X ... i think i am going to stick with what i got :(

Have you have a good read through the EFR thread on EvoM? That thread is a wealth of information.

Yeh, there are some Evo 8 thru 10 results that tempt me..but bascally its 3076 response and power with  better transient response.  Which is ....wishy washy stuff. Tempted to just go 7163 and give it a gut full and at least habe it all in...but that is wooftah 427ci cave man stuff. Its a turbo car....it shoudl be about soaring top end :)

I went from a HTA3076 to a 7670 on my RB25. Dyno graph in this thread somewhere of initial tune. Picked up power everywhere, much better car for the change. Approx 75hp gain (top end, now) since final tune with minimal loss down low. 

6boost, 1.05ts. I have since added heavier waste gate springs and picked up another 30hp and had a slight improvement in response. Next job will be to replace the cooler piping as it goes from 2.5 turbo exit to 4 back to 3 for cooler then exits as 3 straight into 4 upto inlet manifold. It's not ideal.

Steady up lol, I'm not even back yet, 

hopefully not not too much goes wrong and I can have in bolted together and ready to go in a couple of weeks.

already spoke to Dennis, gates are getting plumbed in ?

Excellent!

Where are you getting this info Roy lol? A 7670 will punch holes in a GTX & GT3076! 

Ive never heard of an GT's going 410kw?350-360kw max. Yeah the GTX will blow 400kw but its ALOT laggier! 

 

Whats this its "only transient and response" its better? Transient response on the track and on the street is king! 

 

SAU is being a turd. If it lets me i will load a GTX3076 vs 7670 result for you. 

Both are T3 .82/.83 results on an evo.

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way.

    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
