I love V10's so I'd really like to try this conversion in my 260Z, just trying to work out if it would be possible. Engine is a BMW S85 5L V10 from the E60 M5, makes 507hp is stock form, with less restrictive exhaust system and remap up to 550HP is possible, Its not all that heavy an engine, an RB26DETT weighs 255 - 260kg and the S85 weighs around 240kg so it certainly not to heavy to put in a Z. The engine will definitly fit lengthwise but it may be a bit tight widthwise and I'm not sure if the E92 M3 6 speed gearbox will fit in the transmission tunel and the gearstick position looks like it could be quite far back. Only other concerns are clearance of the front crossmember and steering arm. What do you guys think? Heres some photos of the engine in question:
I've been looking at a few different ways to hook up my Volvo Relay / BMW Sensor / E-Fan set up and I've settled on using the CHTS port on my P90 head, as opposed to the thermostat housing. Beforehand, I'd like to ask a few questions in an attempt to avoid any unforseen complications: 1.) The CHTS port is M10x1.5 I believe, and the sensor I'm planning on using is M14x1.5; will there be enough material here to drill and tap to that size? 2.) The sensor I'm planning on using is typically in a wet port; will it give accurate readings in the P90's dry port? 3.) If the sensor will give good readings, would it benefit from some sort of thermal grease (think heatsink grease) being put into the port before installing the sensor? 4.) Which temperature ratings (low/high fan speed) would be more appropriate for a modified (shooting for around 300HP) L28ET; 180/195 Â°F or195/210 Â°F? Thanks in advance!
Hey all I'm at odds with what to decide on doing and need some suggestions (some advice wouldn't be bad either.) Well here's my dilemma; I have a bmw M50B25 out of a 1992 325is complete with everything except the flywheel and clutch in my garage and I wanna know what you guys think of swapping it into a Z would be like or should i just stick to swapping init the L26 with the round top SU's I got with the car? If i were to swap in the M50b25 i would want to run boost on it because stock they can handle a conservative setup of 8-12psi, but the real dilemma is that I'm kinda unsure of the swap because It's never been done before and I don't really want to open up a pandora's box of problems. People have told me that the engine is relatively simple but that's not always the case. Anyways I'd gladly appreciate any input you guys have as to this swap. Oh and the engine itself is a stand alone system so wiring shouldn't be too much of a hassle.
