Gu rb25

hey mate chasing a radiator fan

Thanks for the advise dale fz1 im going to organise a tune in the next few weeks so hopefully ill have a base line to start at and see how i go from there. Im impressed with its performance considering the weight at the moment so it can only get better

I wish i had never endless money id have a go at the duramax, but already put the rb in just gona get some more hp out of the old girl

That would be different at least i do know a guy that just sold a mighty boy with a supercharged rb think it was a vortek or something like that. I think so far ive been sold on the hiflow from hypergear seems to get good results and heaps of people run them

I didnt think of using the rb30 one i went with the rd28 flywheel, but it seems to have knocked the top end rpm around ive got to dyno it yet but seems to finish up around 6000rpm but a tune might help Its not as bad as u would think on fuel i got 16l per 100 thats with 3 days of beach work and a split highway and around town for the rest and i was giving it a hiding only on 11.5psi though

Did you use the gu flywheel with your rb setup?

Yeah i would like to do the tb48 they make some insane power but dont like the tb45, i already had the rb so thought id would give that a go first, and it uses about half the fuel of a tb45 which is handy for the trips up the beach

Yeah thats right it will definitely be worse, i would think there would be some sort of calculation to maybe figure that out though

Ok the e85 is this the flexi e85 at servos or a race bend? I dont know much about it. Yeah i thought the mambas wouldn't be as good consideeing there half the price but i havent had a great deal to do with turbos so i didnt think it would be alot if its a copy but like i said im new to this. I'll have a look at the hypagear web site now

Ok i would definitely be interested in the highflow option if i can get around the 350rwhp out without squeezing every drop out of the turbo. I have to put a ecu in over the next few weeks hopefully and get a tune on the standard turbo i seem to have lost some top end rpm with the massive flywheel (im guessing) so that might make me go the highflow more than the gtx3071r if ive cut the top end out it probably wont be worth looking at the gtx

If i was buy a motor i probably would of went with that( and i just really wanted to start driving it, took a little longer than i wanted to do the conversion) as they make some good low down power but i had the rb25 already running read to drop in so thought id see how it went first before i went the rb30/25 way also ive never looked at whats involved but im guessing it might be more then i could do myself would definitely be good though. I am still suprised at how well the near stock rb is going with the amount of weight its pushing around though

Will do mate thanks

Ok cool i did look at the highflow stuff a little but thought it might be worth getting something a little bigger so ive got some headroom for later chances are once i get 350 I'll want more dont really want to pay twice but i might have a chat to the hypergear guys aswell. Dont mind being the guinea pig with the mambatek stuff its just hard to know what mods to do as the rb obviously delivers its power different in the patrol with all the wait and im also run a extremely heavy flywheel hoping to gain some low down torque but it messes with the top end a little

Hi guys new to this forum thing but need your help with choosing some new upgrades hoping you guys can point me in the right direction. Ive recently completed an engine conversion on a 98 gu patrol went for something a little more exciting then the 2.8td that was in it instead with a rb25det that i had from a previously crashed r33 of mine, the engine is unopened and has very basic mods so far but im keen to change that very shortly. Im looking for a turbo upgrade at the moment but ive got limited experience so not really 100% sure, but ive been contemplating the mambatek gtx3071r the company seem to have fairly good reviews for the small amount i can find, but im just not sure on the turbo choice and rear housing choice either .63 or .82 so any help would be appreciated. Due to the fat arse patrol the poor little rb has to push around now im hoping for something not to laggy and capable of about 350rwhp Thanks in advance
