RB25det S15 swap questions. - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey guys I’m buying a Nissan S15 with an RB25det already swapped into it. I’ve owned a few SR swapped 240sx but it’s been awhile. I’m looking for some help and suggestions on where to buy good parts and accessories (websites) and what are some must have upgrades for the RB25. I’m finding it tricky to search for upgrades, when you search s15 or 200sx then obviously SR parts come up, when you search RB25 then it’s mixed in with skyline fitments. A few days hongs I’m looking for

What size of 18” wheels should I get 18x? And what offset I’ve heard +12-40.

What radiator to get ( I believe the top inlet is on the opposite sides on SR and RB so will a skyline rad mount properly in an s15

Wouldn’t mind getting a brake upgrade.

I live in Alberta Canada so any canadian sites would be great.

an s13 CA180det rad would probably work, the skyline alloy rads are usually taller so don't really work.

s15 rear brakes will be rubbish so swap in some drum handbrake internals and some 300zx/r32/r33 calipers and discs. use r33gtst handbrake cables-and your s15 front cable.

S15's have pretty narrow arches as stock, big wheels on stock metal = mega camber to get clearance.

Suxh a generically question

Rb25- top mount turbo..foward facung manifold, front mount, standalone, injectors, fuel pump..etc.

Ka24de radiator has proper in and outlet (s14) fits perfect in s15 Radiator, electric fans
Plugs, ignition coils
Fluids..olengine,trans, diff

And NO 18X12-40 will not fit ur stock body s15...check out the wheel fitment thread..like 400 pages of answers..
