Ok all you rb20 guys , i need some help

[Krylonking]

I recently recieved my rb20det motorset , and i didnt get a crossmember , my question is there anyway to modify the ka crossmember or flip it around to make this swap work , please dont suggest buying motor mounts because im just about broke and dont want to wait to do the swap

[Wulfgang]

I suggest you buy some motor mounts. Seriously.

You're broke and you haven't even begun the swap? heh... one rude awakening, coming right up!

[Krylonking]

well im not technically broke , i have a good job , however my fiance is getting on my *** on the amounts of money ive spent lately , dont get me wrong she doesnt mind me throwing money into my car but its a month before the wedding , and i have a tendency to blow my money , what rude awakening is that , ive bought almost everything , i have a intercooler , piping , blow off valve electric fan , exhaust , a new clutch, what else do i really need

[DSMs_Suck]

either get mounts or get a crossmember

[JonPowell]

Or make mounts....get creative, real quick.

[PalmerWMD]

I have seen a couple of RB20 mounts pop up on ebay or even on Nico classifieds.

You may also need some swaybar work, depending on how you mount it. Obviously, if you have your own cherry-picker and other tools, it will be cheaper.

And the list goes on as you feel the need for more power. How much you'll end up spending just depends on one thing: are you marrying your car or your girl?

I think I did both

That list is pretty inclusive, only thing I would add is a new radiator if you can nab one cheap, and either an RB cluster or an aftermarket adapter to make your tach work.

[Wulfgang]

Tach depends.... on my S14, I tuned my OEM tach using a multimeter with frequency readout. It was a PITA to tune (when you try it you'll know why), but I got it to read spot-on from 1000 rpm all the way to 7000 rpm. I wasn't expecting it to be able to be correct at both ends of the spectrum, but it was, so I'm stoked.

Unfortunately, the little potentiometer is inside the tach, which means you have to unscrew the tach, adjust the pot, screw the tach back in, check the rpms, unscrew the tach, adjust the pot, screw the tach back in, check the rpms, unscrew the tach, adjust the pot, screw the tach back in, check the rpms, unscrew the tach, adjust the pot, screw the tach back in, check the rpms, unscrew the tach, adjust the pot, screw the tach back in, check the rpms, to infinity....

But it's worth it for a white-faced OEM tach. Of course, if you've seen where 8000 rpm is on the S14 tach, then you'll know why I didn't test that. No way is that mark in the correct place.

Btw, for the S14 you don't need to use GTRShop's 10k pull-up resistor. Works just fine without it.

[93RPS13]

is it possible to swap S14 tach with the S13? sorry to hijack

[Wulfgang]

You might possibly be able to swap the tach internals, but the gauge face definitely is not going to work. Why swap with an S13? Either tach will work with the RB.

small side note... wulfgang you an EE or something?

LoL she is just counting her money man don't worry about it. Buy some mounts and don't mess around. Mckinney's should be out very soon.
