Gas mileage is totally irrelevant when talking about racing... As is weight. Who cares what RPM the motor is in. If a car is built to run at 7K then who gives a **** about anything under 7K?
and the numbers i mentioned have been in street cars.... Just so you know... Im not talking about a riced out honda....

I know this is an old thread but anyways, he just keeps on wanting to talk trash, especially about our beloved LSXs.
Supposedly, he manages this shop:

I feel compelled to chime in on this. I just got a '00 Trans Am and I have a 1990 240sx with a RB25. The RB swap is pretty expensive, but it is by no means hard to do. It is spoon fed to people now and anyone that can turn a wrench can do it. There are people that do the wiring, have custom driveshafts you can order, motor mount kits. The RB26 is a great motor and can put down some impressive numbers, but if he's keeping twin turbos then he's not making that much power. There is no room in the 240 engine bay to keep twins and run a decent size setup. Since they are LHD the steering column is in the way for anything too big. Has he said anything about his setup? What turbo/turbos he's running? My RB25 is stock for now, but I am going to rebuild it and go for around 500-600 rwhp. The RB26 can do this without a rebuild and whoever said 1000 dollars for head studs doesn't know what they're talking about. ARPs are around 300.
Also, to the person comparing a N/A RB26 to a LS, that's pointless. Obviously the LS will be far superior. I would personally take the LS over RB any day and have started to regret doing the RB25 swap. I started the swap before people started doing the LS1's in 240s and so I've just stuck with it. That being said there are plenty of RB26's making 500+ hp with stock internals. I would say it could definitely be a close race, but from looking at his myspace I'm doubting he even has a RB26. Let alone one in a 240 pushing any power. It's a very expensive swap. At bare minimum it would be around 6k just to get a relatively stock RB26 into the car and running. Keep us updated though. I'm curious as to how this will turn out, especially if he really does have one.

that pink valve covers got to be worth 10hp lol.
I like how the hot air coming from the rad goes staight at the ally intake tube - great addition of heat into that engine!

Show me one street driven 500hp N/A 4 cyl import tuner engine, and Ill show you guys a liar. Its just not possible with current technology to achieve the rpms and VE necessary and still have the ability (or skill) to drive an engine like that on the street. You would be in f1 territory there.

yeah..RB's are impressive motors...on the other hand, turbos make anything fun...but above all seems like the guy's a flake and all talk....and it seems like OP caught him, awesome!
and why is it that engines (other than LSX, LQ..what have you) need FI to compete....
ill give one up for turbo 4's tho...the omni in my sig is a pretty nasty little car, needs a few things here and there...but 25psi in 2.5 liters and 2400lbs...pretty sweet ride....not a 10 second car by no means, but still...SLEEPER!!! lol...

you do realizethat there have been people who have buit 500 whp cars with 4 cylinders and all motor right?
And it doesnt matter if they need a turbo or not. It is just as much of a challange to build a 4 cylinder 2L motor, or a 6 cyl 3.5L motor that can handle a big turbo as it is to build a NA 6L V8.

i have built one nissan. although it was no rb motor, it was a very stout sr car. many mid 12 sec bolt ls cars fell under my blade. i will always have repect for nissan performance. can be very tough and very fast. also, i think this thread needs to be moved to the general discussion forum.
