Recommended Posts

Im purchasing a AEM F/IC-8 for $350 USD delivered.

Supplues fuel mapping, injection alterations and ignition timing maps over 21x17

so that will give me heaps of scope to drop in the 480cc injectors and retune, selling the safc/sitc combo afterwards

here comes 260kw

:P

Call Mike at M V Automatics in Adelaide , as ask for a price on a shift kit. Also get him to supply a service kit as well.... think its included anyway but best to ask.

Others will have to recommend workshops in your local area to do the job. But most shops could do it easy enough.

Once again, talk to Mike at M V Auto's in Adelaide :rolleyes: Sounds like you might be well served just calling and telling him what you want to achieve from the car and see what he reccomends. Don't forget to account for going larger later on..(it almost always happens haha)

Do yourself a favour and get a good sized trans oil cooler. I used a davies craig one inline with the stock calsonic one.

Stan,

Just re-reading your post, and i have to say, i highly doubt you'll get an extra 2-300 rwhp out of it !!!! I estimate a max of about 70 rwhp or 50 rwkw's extra .. So up around 420 rwkw.

I'd be happy to be wrong for sure, but going on the Hp rating of that turbo and working on a conservative (for auto with a medium stall) 15% driveline loss , thats my prediction :rolleyes:

Just got my R31 back from the dyno after tuning - modes so far are...

  • RB25DET
  • Shift kitted & manualised RE4R01
  • Saber FMIC
  • Custom 3" exhaust from turbo to tailpipe with 4" steel cat
  • No name pod filter - AFM removed
  • LinkPLUS
  • 98RON

200.1kw at the tyres - 10psi of boost :cool: bigger injectors and GT3071 coming shortly

Any updates auto guys ? Hows the new housing Peter?

HEY STAN , love the car in the Magazine mate, congrats !!!

My build has stepped up to the next level now. After alot of deliberation, i've decided to go to the rb26 head, and twin turbo's. The 3L bottom end is apparently nearly ready.

Its now costing quite alot ...... its costing me over $2k just to buy all the GTR stuff i need (thanks johno) ! Then the head work and cams will top $5K , so that will happen next year at this rate. I'll be happy to have the bottom end and all parts bar turbo's paid for by chrissy. Aim is 400+rwkw on pump , and 450+rwkw on E85 (Or more likely 60/40 methanol/petrol) .

Going to talk to Mike at MV about a transbrake too... but i think he isn't keen on them in jatco's from memory. Need to discuss getting current 3500 converter dyno'd or tested anyway, as its slipping alot more top end than the 2800, considerably so ....

Also , i will be swapping the LINK G4 plugin (of which i've wired in every extra input available !! haha) over to the LINK G4 EXTREME. Reason being , aside from the extra analogue in's i require, it can drive the low impedance injectors directly with its peak&hold drivers (means it will allow much better control over LARGE injectors (1000cc+) at the low end, idle etc. Also twin knock sensor inputs directly. Extra ignition so no more waste spark needed too.

And i'll build another tech edge wideband controller and run two of them to the link for logging and quicktune !

Ah its going to be fun ! Can't wait to be finally back on the dyno tuning it ..... Anyway, back to lurking.

hitting the dyno again in 2 weeks time to sort out the rpm-/fuel cut.

seems to be boost related

can see it's losing 15kw at top end, due to the rpm cut

should be seeing right on 250rwkw not 235kw

I have just finished building my new RB30 bottom end, goes in for run in tune next Monday and then will add a heap of boost two weeks after that (assuming I get enough Km's on it). I will definitely post new power + torque with my auto against my old RB25 set up. Will also be interesting to see how my 60ft times work out considering my RB25 wouldnt dip under 2.4 seconds with a 4000rpm stall!

Hey guys, yah it is good to see guys out there who like auto's in their skylines..

I love em, although i have gone through a few.

As we speak, i have a jatco 3spd, transbraked, manulised, blah blah, everything done..

With a 2800 stally and on semi's i managed 11.5@120mph with 271rwkw with a rb25/30 gt35r apexi powerfc, stock as a rock rb30.

I ended up blowing my bottom end and decided to go all out.

I have a ported rb26 head going on(just need cam caps if anyone has any) gonna drop a gt45r on, 1000cc injectors, E85 and so on on a forged bottom end. I had to sort some oil issues, (sump capicity, oil pump and head drain and oil cooler) so hopefully this time i will make in excess of 400rwkw. Though i am thinking of dropping the driveline in a holden tonner, just as it will be a weekender. My R31 will become a more of a family car, but using a Re4r03a tricked up box and a basic turbo setup, should last a while..

Cheers, yah i love 3lt torque!! Though never been in an rb20/25 car, but have heard that it has torque from idle better than the others.

60' 1.788. Not the best launch. It would've been better if i could actually get on boost and better on the converter off the line, but i had to control it as i'd just fry the tyres to the 60' mark with the falken semi's.

I really need some big bags with soft sidewalls and large profile to get proper grip. I'd probably get into the high 1.6's if i could and dip into the tens with that setup, too bad now though..

Yeah sounds like you need abit bigger (or smaller size in reality!!) converter to make use of the transbrake.

I just spoke to Mike at MV today about what im doing etc . He said 450rwkw is right on the edge for the 4 speed jatco..... hmmm .... Also, you can get a transbrake for them, however he buys it in from the states (the valvebody), and its fully manualised, running full line pressure always...(ie really drags only type car use) ... about $7-800 odd....... So that put a stop to that plan......, will just have to sort out weak as piss rear brake problem so i can stall up the old fashion way.

He also agreed something sounds wrong with my converter also, as they aim for only about 6-7% slip up top...... i have alot more . So when motor come out, it'll go down. They don't do the converters themselves, they have a contract with a converter shop. not sure which one.
