RB25 Swap for 240

[Godzillarb26dett]

What does everyone think of the the RB25 swap in the 240sx/s-14 silvia....im thinking fo taking that swap in stead of the SR20...im goign for higher horse power....also looking on advice on what turbo to look in to

[SHIFT_Lock]

but what about a godzirra rb26?

[RefriedNismo240]

its one sick swap man. but be prepared for some custom work, lots of members here have been running into problems with fitment, ie. oil pan sits on sway bar, hood doesnt close, the usdm driveshaft doesnt fit. But if u search around and read up in the rb forums many of these problems have been solved with custom mounts or using the crossmember from the r33 and r32

[Godzillarb26dett]

SHIFT_Lock yeah i know having the RB26 would be sick....but right now i don tahve the funds to attempt doing that...... and RefriedNismo240 thanks for that advice....do you have any links to some good RB forums that i can look at.....othe than that thanks....what turbou think i should upgrade for this RB25 swap???

[RefriedNismo240]

i was talkin about the RB forum that is on this site.

[Godzillarb26dett]

RefriedNismo240 i know that you were talking about te forums here but there is not as much info as i would like....i was asking did you have any links to any other good RB forums......

RB25 isn't too bad. RB26 is VERY involved.

If you are going for best Qmile times, go RB. If you want to hang in the curves, go SR.

just my 2cents

With the mckinney motorsports RB25 mount kit the RB25 is drop in, id doesn't effect handling they way people assume it does. The motor does weight more but not any 150lbs more than the KA. The Mckinney mount set also makes the RB sit low and farther back for bettter weight distribution (with no modification needed to the chassi or swaybar/oilpan).

[Godzillarb26dett]

J-SPEC Tuner i will look into the mckinney mounts...sounds like alot less work

[Onizuka]

it makes for alot less work but you pay for em, i think they are about $1100 shipped.

^^^^^^ this guy is smart, or has alot of time on his hands

[Onizuka]

i just spend WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAY too much time researching as much stuff about 240s as i can

[Godzillarb26dett]

I think that we all see......the shop that im looking to possibly do my swap i will discuss mckinney products and see what will work out

[karter74]

just make sure you know that like everyone says, you will need a lot of custom work done (driveshaft, the electrical to mechanical speedo, etc.) How fast do you want to spend?

that has absolutely nothing to do with anything what so ever.

Ever see the jms rb20s13? a typical rb not the 26 weighs about 50 lbs max over a ka. take the battery throw it in the trunk. remove the following: front bumper,ac dryer,ac condesor,charcoal can, old mechanical fan,ac lines,battery tray, window washer bottle,ac fan. and also if it's a s13 if you do a silvia convertion that will lose 27lbs also.another thing if you use mounts IE -UH- or mckinney the motor will sit lower and back which also helps weight dist.

i hear this weight dist. bs agument all the time. and even from people who pull the whole interior and that can mess up front to back weight but it doesn't matter.

also get a car corner balanced.

[Godzillarb26dett]

I am well aware of the steps that are to be taken in the instillation of the motor that has been worked out i have no problem with at all....and as far as who ever said that im looking for quatermile or drifting....im not sure if you ever see this but ive seen skylines drifting also......the weight diff... can be worked out.....im not worried and i will be turning this car into more of a highway beast .......im looking for higher horspower with out totaly pushing the limits on the sr20 so thats why i chose the rb swap

[Godzillarb26dett]

Oh yeah one more thing to add....as for my original ? i wantes to know a good turbo set up for the RB25
