Rb20 Turbo Sil80 Drift Car

[dooby87]

bought a 180 with the front smashed in witch we will be converting to a sil80 and dropping an RB into.

some people believe that they can be a bit front heavy for drift but gonna give it a crack anyways.

it will have FMIC, pod and probably bigger fuel pump. and will be running higher boost on stock turbo (about 12 - 14 pound)

will be getting coil overs and strut braces as well.

how do you recon it will handle and what sort of power do u recon i would get???

my mate has a s13 with a rb20, hks 2540, microtec and 550cc inj. its a weapon laggy but a weapon. he makes 192rwkw on 14psi (in darwin too). make sure you get a 25 box for it.

[paulr33]

keep the SR in it

hks 2530

4.3 diff gears

[dooby87]

gonna get a a different box wen the rb20 one shits it self, till then will keep the original

should hold up for while with the minor mods

[R31Nismoid]

stick with the SR

HKS 2530, or a JDM S15 turbo... pretty much gonna be a parrot type responses

My drift car is a Onevia with a Rb20 in it and a RB25 box.

Completely stripped interior just a RB25 highflow, remap, 3" exhaust, front mount, Tein coil overs, welded diff and a 5 puk button clutch.

No problems drifting whatsoever.

Do it and have fun

The Cefiro cross member is the best to use as it will sit the engine a couple of cm lower then when using a R32 GTST cross member.

Just get your suspension sorted out and it will be easy to throw around.

A 1 piece tail shaft is fine and most big truck shops like Gibbs can make you one up relatively cheaply.

If you have any questions feel free to send us a PM.

thanks for the info, looking foward to the rb going in,

will be doing rather similar mods in the future.

will be a nice change from my ca18 de silvia

if you are going to go rb go rb25. if not stick with the sr20. the sr20 has more torque than the rb20, and almost the same power.

[dooby87]

yea but RB is alot cheaper.

i got RB with gearbox, wiring loom, ecu, turbo, xeady heavy duty clutch and oil cooler for 1300 bucks

I think what people are trying to tell you is how much effort and cash is needed to make it a reality . A long heavy motor thats no torque mountain in std form - for drift . No competitive engine is going to be cheap regardless of if its in the car or on the floor . I think you'll find in this day and age more factory and aftermarket goodies for SR20's than RB20's which means greater availibility and lower cost for the right bits . I can partly understand why in the US there is this S13/RB20 craze - no R32/33/34's or SR20DET USDM cars . If they'd had the R32GTST they wouldn't bother converting S13's . When you can have 400 ft/lbs of torque from a half serious SR20 at 4500 rpm why would you plonk an RB20 into it ?

One more time , said this last time .

stick with SR...... we have a S13 with a killer 26 in it and the built SR was still a better track weapon. Putting a RB20 makes zero sense.

Putting a RB20 makes zero sense.

...except they are cheaper, stronger and possibly make the same/more power. Im yet to be convinced that a std SR20 can make the power and response a sorted RB20 can. I think its more to do with the fact that there are so many ppl spending money on SR20s its easy to find a good one. The same cant be said for RB20.

They arent the best engine. But if dollars are tight then i think the RB20 should be on the radar.

...except they are cheaper, stronger and possibly make the same/more power.

id say that is more a tuner fault, SR's are far more det prone than rb20s for sure and 90% of sr's failures are ring land and the rest are big end...... due to det. i have only ever lost one SR and it was a dodgy HKS injector that stopped working.... killed number 3.

sure they are cheaper but by the time its installed 2500 goes quite a way to making pwr on the sr. if it is NA to start with then yes probaly makes sense.

i see SR packages from 1500 regulary you just need to look.

as slide said im using r32 gtst cross member and i needed to lift the bonnet a bit to fit the engine under it

[dooby87]

what sort of cross member do i need to get it under the bonnet??

[Slide]

Cefiro

If you can only get a R32 GTST one simply weld 2 pieces of steel on top of the cross member to drop it down a little

[dooby87]

hopefullly i will be able to find a Cefiro one, other way sounds a bit dodgy.

if anyone has got one for a good price let me no. thanks, will pay postage if need be
