Rb's

[StupidBikerBoy]

You know how many times I have heard that before?..LOL..I can make an RB30 fit with no problems. Shit I helped make a VH45DETT with a 5 speed fit into a 300zx...it runs and drives today..and everyday...for the past 2 years....yes...we did have to cut the hood on that but everyone said it could not be done. The RB30 isnt but about an inch taller than the RB20 if the RB25DE head is used

.

I believe thats exactly what I said, you'd have to cut the hood. And to be exact, the RB30 block is 44mm taller than the 25 or 26 block.

Im not going to talk to much shit about it but I know if I put 5g's into 6g72 or an rb26...with the RB26 being in a 240sx chassis...the 6g72 will destroy the the RB26.

We can internet race all night long. Im sure thats possible, and so is the opposite. It depends on quite a bit. Parts for a 6G72 are typically more expensive and theres not really a big following for them. And you have to be joking about a 6G72 destroying an RB26 240. 1000 lbs less weight AND more power potential.

What does your 6g72 put down? I have less than $5k in my RB26 build.

RB period in a 240sx is not smart...to do it right and get correct power you need ALOT of money..thing about..one KEY factor is its a front sump engine in the 240sx...you need a custom pan...thats 1200+/- right there. Mount kits, wiring, etc..etc..etc..

See now I'm starting to think you don't know anything about RB's or swapping them in a 240. You're way off.

1. Show me one person that spent $1200 on the oil pan. Mine cost $120 shipped BRAND NEW. And you only need that on the 26 swap.

2. To do it right and get "correct power" doesn't require any more than any other engine would, especially an SR. This is not the 90's, RB parts are not hard to get anymore.

3. Driveshaft and IC piping is the ONLY things you have to have custom. You can mount an RB in a 240 with STOCK parts.

4. Wiring is an issue with any swap

SR is cheaper and its faster in a 240sx.

As I said before, RB is not always the best bang for the buck. Yes an RB25 swap is a little more than an SR, but it has more potential. Stock for stock the RB25 would kill the SR.

To say that an SR is faster in a 240 is just rediculous.Yes you can make one faster than a mild RB, but at the cost of reliability. The RB has more displacement, flows better, more valve area, has a MUCH stronger bottom end, more potential, etc. The only advantage the SR has is weight. The 26 is essentially Nissans race engine. It is capable of 400+ just by tweaking it in stock trim. Theres plenty of RB26's running around the US pushing 600+ on stock bottoms with ne issues. There was a GTR that dragged in aussie land that put down 1800 HP on the stock bottom. You may do 1/3 of that on a stock bottom SR.
