Rb20 260rwkw? Help Me Please?

[ez 10]

Hey Everyone,

Im hoping some guys out there can help me ive been a member on here for along time but havent posted in years ive been in and out of RB ownership for years mostly 25s and 30s but a few months ago i rejoined RB ownership with the purchase of a s13 180sx with an RB20 fitted.

Now the car apparently had a built motor ( i belive forged flat top pistons,balanced and knife edged

crank,forged con rods,apr stud kit,flowed rb20 head) now with no reciepts im willing to take it as a stock motor for tuning purposes however the tuner who did the current tune did say it was making good power.

My question exists that i would like to make 250rwkw-260rwkw or there abouts now i would like to know what mods will get me there on pump fuel and if not then ill be making the change to E85 which id prefer not to do.

If theres any guys out there with high hp RB combos what do i need to add to make the power as i had my current tuner tell me the goal was not achievable

the car has the following mods

Haltech E11v2 with boost controller

Garrett GT3071r .83

custom manifold

38mm turbosmart progate

modified stock plenum forward facing

Front mount cooler

JJR Coilpacks

3inch exhaust

custom 3inch dump

Alloy Radiator

Walbro 300rwkw? apparently rated pump

Now the question guys is does this combo have 260rwkw in it if so then i guess i should use GTR injectors if its not then i should be opting for bigger 700+cc for the E85.

Before anyone posts yes i did use the search button but the threads and crap attatched to some of these threads including 90 page long threads and unfortunately after about 3 days of reading i couldnt really find anyone with a similar combo to mine.

THanks in advance.

Yes. I have a similar combo to you and mine runs roughly 270atw. Your setup should get you closer to 300 i reckon.

I'm running...

stock bottom end

poncams

600cc injectors

highmount manifold gt3037r w/38mm tial external gate

power fc

avcr

z32 afm

walbro pump

3" dump and 3.5" exhaust

boost controller

etc

Maybe try a different tuner if your not getting the results you want.

yeah looking at your shopping list it seems you should be close to that power already.

how much power did u get out of it?

did he do a full tune on the car?

how much boost were u running?

and i would go the bigger injectors and u might even be suprised wot more u get

at the moment im runing out of injectors at around 220 odd but it looks like i will get some GTR injectors ( which are apparenty good for like 270) and see
