RB26DETT into S14

RB25SX · Post by **RB25SX** » Thu Jan 15, 2009 9:03 am

Yes, HKS2540's. Can get a set with 4000km from japan for $1250. Shipping is another R4500, then duty +++ ads up to about R20000. Or I can fit a T66 or GT35R single for less money. But must get car sorted before I get there.

Should go on dyno today. Was smoking a bit after a long time running, so turbo seals might be leaking. Will see what happens when its under boost. Not an easy job to remove turbo's, so hope to run std ones for a while.

Update: The car is in a drivable state now. Boost set at 0.5 bar for time being to sort the car out and make sure it stays on the road. Power @ 0.5 bar is 225kw. Response from the twin turbo,s are realy good, not much lag, but will go much better at .8-.9 bar.
Fitted a 50mm alum. radiator, been having problems with water temp.

Fitted 320mm front discs. Nissan Murano discs are a sraight fit, just need to space caliper out.

Fitted 18" wheels, since other mag wheels didnt clear the front brake caliper. 18" also looks better

looks awsome..

very interested in your brake setup there.. its nissan murano discs you say?

is the hat height, spigot and pcd all the same as the s14 discs?
also did you make your own spacers for the calipers and where did you buy the discs?

lots of questions , sorry, but i was wondering if those discs would work on a z32..

The Murano discs have 5/114 pcd and same offset as S14, so direct fit. 320mm x 28mm thick vented. Had them grooved and electroplated. Can buy the from any spares place. I bought from supplier, cost R1550 for 2.

thanx mate, thats frikken awsome, that means i can substitute these for real z32/s14 discs which we all know are hard to come by and expensive..

having to space the caliper out by 20mm means more leaverage/braking without screwing around with the abs calibration too much.. win/win

gonna look for a set tommorow, try this out.

did you make the spacers yourself?

Sorted out the "aparent" over heating problem, seemed to be a faulty sender unit or air in the system.
Had the car on dyno today for some final mapping. Resulted in 260kw , 400nm @ 0.7 bar on pump feul. To be safe on the ceramic turbo's, boost should be kept under 0.9 bar. Not bad for a stock standard RB26DETT.
Next will be some D2 coilover suspension.

All stock, 440cc inj, 4bar feul presure, with Walbro pump. I dont think its @ wheels, should be at flywheel. Still, thats same nm. as std R34 GTR with more kw. Stock turbo's can go up to 1 bar, but its risky with ceramic exh wheels, they are known to brake.
Next upgrade should be turbo, to get 300kw+

nicely done

Got some new bits for the motor, Stainless split down pipes. Should give a few extra hp.

Also fitting Electronic boost controller and wideband O2. Aiming for 300kw on pump feul.
