I didn't read the whole thread, but my 2 cents.
the rb20 is a fun motor, if you wanna build the motor. It isn't the route to go if you wanna just plug and play. I've seen some sick rb20 builds, but they all were built, or re built, from the ground up.
If that is something you are looking to do anyway, then by all means, go for it. Not too many RB cars in the area, so it would have that flair you're looking for...
have fun, and post up the progress.

 

Ill say go with the RB20. Youll save money in the long run. Because by the time you get it installed and refreshed with new gaskets/timing belt/water pump, you still havent spent as much as you would for an SR/RB25. And you play with the wiring about as much as you would with an SR anyhow. RB25 is where the wiring gets tricky. Youll bang the firewall for any RB.

If you go RB25....do it with an RB20 trans. Sure, they are weaker, but you can use the stock S13 driveshaft with it that way, instead of having to buy a custom made one.

Personally, both have their pros and cons. 25 is more power out of the box, but costs as much as an SR(makes more power than an SR which is why I cant understand why people still do the SR, but thats neither here nor there). 20 is as much power as an SR, but costs far less. Means more money for mods(compressor/fuel upgrades).

I gave up my RB25 project to go KA-t. After spending around $1200-1500 in parts, Im starting to wonder if it would just be better off to go RB20 like I wanted to in the first place(even before I went RB25). KA-t is nice, and I am glad that guys want to give the engine some love. But an engine that was turbo to begin with seems like a better starting point to me.

And no, Im not speaking out of my ass. Ive actually done an RB20 and an RB25 swap.

 

you should put a sherman tank powerplant in your car craig.

 

built sherman tank motor ^ see above post

 

kind of funny, the first time i have ever ridden in a RBswapped240 was on sunday.

it is a RB25 with a single 2530.

this was probly one of the most responsive cars i have been in, besides dedicated N/A race cars.... it was amazing.








i know it would be more expensive than a RB20, but if you want the torque... it is worth the wait. he is running 275`s on all 4 corners and this car is a beast.

 

^that is a almost factory clean swap..

 

That is an awesomely clean swap, looks great!

 

The sr is "the norm" for a reason.
i know where u can get 1 too, for only 18,oo coin!

 

seriously. stock airbox too. shit

 

idk if you knew about this but the spray tire shine stuff that works really good on tires also works really good on motors. if you wipe everything down then spray it almost any motor will look that clean. trust me it works ive done it and where ever you over spray it just burns off when you drive.
