Stock Rb26 Power Limit On E85

[jukic.j]

Sorry to crash thread but i'm trying to find some quick answers without starting a new topic. I have an R33 GTS-T with a GCG Highflow turbo (XTRGTST). What power range could I excpect to get out of it?

250kw.

Now back to e85 goodness

Hows the car going usmair? Put it on a dyno yet?

[Hadouken]

ok so i cant wait for the ol' 30 to be built, i have got my walbro e85 fuel pump and my injectors will be here next week then its off to Jez to get this happening

should all be done in the next few weeks so il post up the results...

Has jez touched you your car yet?

[jukic.j]

Already got 240kw without e85

Yes he did....it felt good he said

For some reason it was running out of fuel, wasn't the injectors coz they were at 75%,

Made about 360ish at wheels.....we did see more then 370 though

Gotta run a few tanks of ethanol through it, change the filters/clean the fuel filter sock and go back to make sure everything is 100%

Huge difference in torque and thrust lol

[SiR_RB]

I rewired the fuel pump for 14v but il need to check to make sure its getting full voltage at the pump

Or could be a fake.....dunno

Steel gears that you can see at the bottom of the pump means its genuine

What tends to break on these at this power level? Do they normally just spin a big end or do they throw a rod out the side of the block haha?

Im running a 35r at the moment with just over 500hp and was thinking about changing to e85 for a bit more but a bit unsure if its going to hold

up to the extra power or not and what will break if it doesnt.

[scotty nm35]

e85 would allow you to run a much smaller turbo for similar power levels, making the car much more responsive and faster overall.

Who knows what will break and when, but at least there will be no DET which is what usually kills motors, built or stock.

Ethanol will give you more torque, but the way the power is released during the stroke should help with longevity, and your exhaust temps should be around 200c lower also. The only real downside is less K's to the tank.

I'm at about 18 months running 600rwhp at the track and now running around 700rwhp and 2 bar for fun times...

Head studs are a must and probably a head gasket, so are the normal oil fixes but apart from that they are very strong

[arsnic_apple]

So do you personally think it's worth pulling the motor out just to do the same oiling mods that you did and chucking in some new head studs and head gasket?

Haha your recent results Simon was what inspired me to put mine on e85

[SimonR32]

Yes 100% worth it, a lot cheaper, easier and faster than a rebuild

[GTScotT]

If you are prepared to build the motor but want to try and get away without you can always try.

Whilst the motor is good for the power in described trim you should bear in mind that the longevity of the motor is also largely dependent on condition and the life up to that point. Much like tests on SR20s, lots of people kill them at 200kw and then others have tested them to 400.

Be it myself I would stay within the known constraints but would boost it till it blows. However I would be prepared to replace the motor should it grenade.

GL and keep up posted

[arsnic_apple]

Yeah i have the mindset that I'll have to build the motor eventually and to be honest the car really doesn't see a real hard life. Simon you did oil pump gears and bigger sump if i remember correctly? Did you change these yourself?

Anyone else running 400kw on a stock 26?

What's a safe boost limit?

Safe boost is just before it pops.

[KING87]

I been running 430kw in an un opened 26 for a while now apart from a set of Tomie poncams.

HKS 2530's and 25psi

[Blackkers]

is there much difference in overall strength between R32 to R34 Rb26's? I haven't looked much at the GTR motors. VCT is where it's at for a street car

[Piggaz]

Apart from the short nose crank pre feb 93, iirc, not much. Slight cam profile change in the 34 but nothing to write home about.

LOL looks like your the guniea pig.
