cant believe ir just read 13 pages of all this

1.4 sixty foot and 129 mph and only a 10.8

you need to changes gears faster that thing will go 10.1 with ease.

or get an auto.

good work i like it.

our cars would be a good match up.

Yeah love to champ

Reason why i didnt flat change is the scared to blow the box and thats useless money

I have just finished putting the auto in and have driven the car but have noticed i have only got around 4-5 psi of boost

I am going to check this problem out and Do a comparence dyno printout from Manual To auto.

The box i am running is a 2 speed powerglide with transbrake.TCT Converter With a mech Diode

I have also got a Chrome moly 1 piece tailshaft made to help with the transfer

I will post tomorrow the difference and will be back at the track in 2 weeks

My next aim is to run in the 9 second area.If it cannot be done with the standard head which i think is possible with some Nitrous but if not i will use the Solid lifter head which i have got with a steel head gasket.And that also goes if the head gasket goes i will also change heads.

I cant believe that rb25 is still going. I hope my rb30det can make 400rwhp in stock form and be reliable!!! if that rb25 can do then mine can get close to it im sure :cheers:

Hey Guilt-Toy, I have an internally stock (apart from poncams) rb25 making 410.7rwhp and it is running fine. It is on a conservative tune with timing advance and a/f ratios to keep it running as long as possible. But then again others running less have had the motor pop. I guess a lot has to do with the tuning and the condition of the internals to begin with.

Cheers,

JB

Ok have run the box in a bit on the dyno and have done 4 power runs

Without modifying the tune i have made 477 WRHP with the auto on just 18 psi Boost

Before the auto i was making on average 500 RWHP on 18 psi of boost on pump fuel

I will post the nitrous compared sheet next week when im back from Newcastle as well as this sheet

But as far as what i can see i only lost 23 RWHP

I also tried to spool it on the brake and found it couldnt get more then 3 psi

I tried with the nitrous and it flared straight away

This is due to the converter being a Transbrake Nos setup converter

The converter Was built by John @ TCT in melbourne which i think did a unreal job and the box was built by Joe @ Wollongong Automatics.

I should be back at the track in 2 weeks now

Waiting on the car to be teched.

My aim is to run in the 9 second area and further till something gives way.If something does i will change motors and try eventually to run into the lower 9 area.

Any questions just ask

1200hp would be good for 8's or 7's wouldn't it? whens the beast arrive?

Im using this engine in my Full chassis car that my father and i am building

Im using the other engine i have in this one

the one with the solid head ETC

i do

but i am not allowed to Show the Setup

(FAMILLLLYYYY MATTERS)

when its closer to being @ the Track ill post some photos of it and the car

This is what is in the Motor im putting in this Car

-RB26 Crank

-N1 oil Pump

-EAGLE H beam Rods

-ACL forged Pistons

-ARP main & head Stud kits

-Cometic Head Gasket

-RB25 Head with TOMMIE Valve Springs,Solid Lifters,Tommie 272 @ 11.5 lift Cams

Aiming For 600 RWHP+++ and a low 9

hey bro, look ive just spent the good part of 2 1/2 hours reading this thread and its my bloody birthday, ive even held of on the cake till i read this, lol. What a thread, one of the best of read on this site. To the doubters out there, well you said he was dreaming and the dream came alive. The power you got out of the engine was pheonaminal, it makes ya think what a 13 odd year old engine can actually achieve. To the believers, aim high and you can go far. I know that the availability of a dyno and the mind of someone like your self (mechanicaly) not everyone has, but you took advantage of it and done well. That engine had a lot of balls. Anyway good luck with the new one and who knows what power you'll hit with this one.

LOL HAPPY BIRTHDAY BRO

Anyways ill post some picts of the Internals

If i wasnt Selfish and didnt try to get more power out of it i would say it would of Lasted alot longer but i was always Trying to make more instead of leaving it

Anyways

Shouldnt be to long

Cheers mate, but also in saying that you were selfish, you also did something that im pretty sure a lot of people have always wanted to do but have never had the balls or money to do, run the bitch as hard as it could do and not care about the consiquences, i think a lot of poeple will actually understand that the more you look after the car, the more power can be put into it. In saying that, within reason ha ha.

Damo

After all the Motor Has been through i can say that it is possible to Make 470 RWHP safely on a Street RB25 Standard motor and make it last on Pump Fuel.

To make even more Safer power i recommend Changing the Head Gasket to a Tommie or Cometic and Upgrading Cams in which you wont have to Run as much Ignition Timing and Boost.As for the Bottom end i think that all of it can last.

The main Reasons for the Car making the power is

1) suffiecent intercooler (this is what Makes your Power And makes the Engine last Due to A stable Low Air Temp)

2) the Design Inside the Plenium

3)A Efficent Turbo (there is no need to Get a 1000 hp turbo if all your looking at is 600 engine HP)

4) Great Ignition Setup which is pretty basic and can get even better like the Next setup im doing which runs 6 coils

5) A good ECU

6)Reducing Load Off the Engine EG Clutch fan

7) good Fuel Supply

well done mate its lasted alot longer than the knockers on here had imagined. bout time someone showed em they are keyboard mechanics and dont actually know from there own experience, just from "i heard ..." and "i reckon ..." comments said on forums.

good luck with the new setup

Thanks Mate

I havent commented yet and thats becoz I know f**kall about what destroys a good motor at that amount of power, but its interesting to note that it was No6 that lost compession, as that piston seems to be the one that cops it alot, higher temps and first to lean out, have you accounted for this in the new setup?

And Oh well done I would be happy to have your dyno hours :(

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
