12.8 on r-comps and 12.9 on genuine street tyres :)

plus i ran a 1.8 flat 60 foot on street tyres but clutch stuck to flywheel and couldnt smash box into 3rd haha

that was with enough power to run over 113mph (the run before), low 12 went begging!

i'll race u in the gtr instead hehe

Had my first tune today with the new engine got 1500 klms on it so there more potential in it yet,tuner thinks the plenum is stoping it atm but very happy with the result

cheers Peter

HOLY SHIT!

Decent numbers there!

I'd also love to know the spec's on the motor too!

sorry guys been busy

40thou oversize aries pistons

25 crank make it rb2.1ltr

ported and polished head

hks cams and cam gears

performance valve springs

garrett gt3040r turbo

hks low mount manifold

3" hks zorst

hybrid front mount

cai to standard airbox

550 sard injectors

Hehehe. Std RB20s pulling good numbers and good times. And legend finally gets his 20 back on the road. Great stuff peter. I cant imagine how much fun that car must be to drive. How is it for traction in top of 2nd and 3rd gear? What boost? Does the head work help it make power? Your thoughts?

LOL..i want to throw the HKS manifold and 3076 on. :kiss: 20G just wont make the top end i need to scare the big boys at Phillip Island and Sandown :P

im curious also about the head work, what exactly was done to it and whether its worth it bang for buck.

hehe...there are still a few ppl down here that attribute the speed of my car this year to a cheater spec motor. Its just that for the first time in a good many years i have a working diff, good rubber and a tuner that knows what he is doing, so not having to drive around too many problems. Cant wait to get the new suspension working

you'll run into the 12's, but a low 12 required stock rear strutts and coils, i ended up with positive camber on the back when we put them in which sqaured the tyres out on the launch.

and you'll need micky thompson e/t's

my 13.1 in street trim was on 20 psi aswell, when i up'd it to 24 i couldnt get it to hook up till 4th

the 16c rear isnt THAT bad hahaha, i see full boost 24psi by 4700.

Do you run ARP head studs and aftermarket headgasket? I'm just wondering how far I can go with the boost on my RB20. I was planning on a max of 25psi but if your doing that on the stock head studs I might just push for 28psi. I'm running the head studs, Tomie headgasket, sard 800cc injectors, Prescion SC61 turbo, PFC, Tomie 270 cams, rips intake ect. I think I might need to run alot of boost before that turbo is happy. I just hope she will hold the PSI and I won't try to blow the motor.

Hey guys

Just back from the dyno day ,had issues with fuel leaning out at higher rpm but was pretty impressed with what it made by 5300rpm will post graph

Roy ,its great to be driving it again feels awesome pulls like a train but its still a new engine it will get better as it beds in some more its got like 1600k's on it now so there lots of playing to go.On high boost what traction and high boost is 23psi

I'll try to answer your's and Johns q about the head work and its value at once .With the old bottom end I never had any trouble with high rpm's leaning out it could also be crank and bigger bore that helping this but alot more air flow will cause it to so the 1mm oversize valves and I spent a bit of time doing the ports again in my opinion has help with power but I think its helped more along the lines of torque its feels heaps better hills that i'd drop down a gear b4 now cruise over it top no trouble but more than that i think its reduced lag time a fair bit you'll see it in the dyno graph I got today as I didn't get one when I got it tuned 4got was to stocked with it toping 300rwkw

Butters

it would if I had 82mm pistons but mine are only 40thou oversize 79mm standard is 78mm

I'm thinking about doing a post on this rebuild with all information I have as took heaps of pic's during build but thats for a latter time his todays dyno graph

post-7066-1179560662_thumb.jpg

you can see where his backed of at 5300rpm here but here is where you can see where full boost has come in all the work I did with the flow honing has paid of and the head work has helped this as well usable power

the motor hasnt even had the rocker covers removed let alone aftermarket gasket/studd's :P

that is bullshit response! at 4200 you are making 250kw!!! awesome. Maybe i should turf my RB26 and whack in a 20?

i cant believe it thats f**king insane :) i think i almost should have stuck with my 20 now.. and poured as much money into it as i have my 26

    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
    • Well they got my money but they are not getting my gearbox !
