Burning $1000 - Brakes or Diff?
onboostR33 replied to colourclassic's topic in RB Series - R31, R32, R33, R34 (1986-2002)
HFM do a big break kit for 33 gtst around $500 for front and $400 for rears have some on my r33 makes a big difference to stock alot more brake torque -
dude PSI and air flow are two different things flow is the volume of air, psi is the pressure or force how fast the air travels,, think of it this way get a foot pump a bike tyre and a car tyre pump the bike tyre to 20psi count how many pumps it takes then, the car tyre to 20psi , the car tyre has alot more volume than a bike tire right? there fore it will take more pumps to get it to 20psi at the end you still have 20psi pressure in both tyres but the volume of air will be much more , same as a turbo mate you understand?

hey dude these guys are right the bigger turbo will push more air out of it just look at the inlet size of your to4 copared to the stock one it is the volume of air PSI is pounds per square inch there fore this is the force the air has not the volume of air your ecu is probally retarding the timming at this rev range and you air flow meter cann not read the amount of air that is being pushed througt it im running a gt 35/40 turbo with a micro tech lt10s ecu with a map sensor that is better than an air flow meter map sensor reads the manifold absolutte pressure no need for air flow meter INVEST in a good ECU this will make or brake your engine all these mods are a waste of time if you are not controlling your fuel / spark properly!!

YEAH i see your point so if i wanted to make 250- 270 kw using e85 later on when it comes more avaliable how manny cc min injectors will ineed? what do the stock rb 25 injectors usually run at? how much more fuel do you have to inject using e85 comrared to 98 unleaded?
-
interesting rolls guess i wont know unless i have individual lambda on each cyl as you said , was thinking to hold out for a re tune untill there is a supply of E85 in the illawarra area, read guilt toys thread on this seems like he did not have many drammas are you running E85 on yours whats you oppion on E85 is it worth me holding out till this stuff becomes more available ? or just retune on 98? im only gunna run big boost when i go to track days etc not every day..............
-
Rolls i gather you mean cly 6 is the last cly near the fire wall , so your saying this cyclinder is getting less air than say cyl 1234? or more cause if cyl 6 is getting less than the others wouldnt it be running richer because cyl 6 is getting the same fuel as all the rest? is it worth getting a proper front facing plenum? that is properly tuned for front intake?
-
Yeah that plennum was on the car as ibrought it only had the car for 6 months so just tidying it up at the moment, new oil in everything, how much is a good plennum worth with the front inlet, i gather this was cut and welded, but the car runs fine, is this a beter setup from the stock one because it does not go over the top of the motor wich would heat the air from the cooler or was it done so the gt 30-40 monster coud be fitted ? its running 12 psi now making 205 kwatw is this a good figure for running 12 psi? should i be aiming for 250kw tune with around 15-18 psi, also im goin to get a duel stage boost controller so i can switch between 12 psi and what ever the new psi i will be running, joey joe how would this setup lean out cly 6 ? i have taken all the plugs out and checked them all , all same colour coffie brown on the electrode and black outer so i guess all the cylinders are getting same fuel air ratio............... is ther a way you can tell if the last cylinder is running leaner? , Rolls my motor is running richer at top end know this cause she blows plenty black smoke on full boost , so your saying some tunners tune learner to get the power at top end should it be blowing black smoke when on full boost this is ok right?

hi guys just a quick question has any one converted a r33 gtst front rotors to a r33 GTR front rotor setup, mine has abs so can i convert to the GTR front brakes with out wrecking the abs sensor on mine, also would it ber worth it ? or just get a good set of rotors and pads for the stock r33 gtst?
-
Rolls, true i think this turbo is to big for the power i wanna make but it was on the car when i brought it. boost does not come on till 4 grand, i used to have a mitsu galant gsr with a 4g63 2 litre with tdo4 stock turbo i notice the difference between the two, boost was on at 2 grand in the galant and had limited top end , i dont wanna change the turbo now just wanna work with what i have got. how much Kw can you get out of standard internals , i relise the tunner has a big part in this but if tuned properly can you run about 18 psi with stock internals? on another note has any one had experance with variable vane turbos on a r33?
-
hi guys just got my self a r33 gtst recently and wondering how strong the standard internals of a rb25 are, the engine has a garret 35-40 turbo, external waste gate microtech lt10s ecu, front mount cooler and is running 12 psi making 205kw dyno tuned at the treads i wanna know how much boost i can run with stock internals have been told different storys looking to make 270- 300 kw at the treads, i realise i will need a bigger fuel pump and injectors what is the best set up to achieve this power with out killing the engine cheers any info would be great!
