I've put over 20k (rather abusive) miles on this truck now, no problems whatsoever. I just put some 16" wheels on it with some bigger tires.
OH MY GOD!!
ive been seeking this info for quite some time but for a nissan rb25 carby build.... ive currently done a rb30 carb build and used a vacuum advance dizzy that comes stock for rb30's. (works great i might add and runs a nice 40 dfav carby :p)
so im still a bit gob smacked about this but what your saying is you had a efi car with an ecu and cas? and you slapped a carb on it and it still advances the timing??
if so this is great news for me pls confirm wether or not this will work on an rb20de/25de ecu and cas
Well I don't know, but I know how you can check. See post below.
Frankie!!!!!! this is it man, what I wanted to do to my pick up... it's an 87, TBI Z24i and just not working for me, half throttle or more kills it, like it isn't getting gas, or is flooding...... tired of the computer and injectors and junk, just want a carb! so, to clarify, here is my confusion...
1. can I use the stock dist, (CPS)? or will a regular dizzy work?
2. did the throttle bracket take much? I can fab most anything.... stock cable right?
3. can't I just swap a carbed intake onto the head, and toss the TBI intake unit as a whole? or do the ports not match up?
4. what is the better carb to go with from weber? I can get my hands on a 44mm SE CV carb from a harley big dog, and had one on my 87 Samurai DD/RocKrawler, it was sick, great gas mileage, and was turning 33's @ 75mph.... should be the same right? gas, plus spark, plus air and we have ignition!
any ways, thanks for your posts, I think you hit the nail on the head on this one... I was wondering how to go about it and here it is! computer don't know the difference, everything is just the same, other than the crappy TBI stuff! same comp, same dist. (CPS) haha... nice..
1. yes, and also yes
2. The stock throttle cable bracket required 5 minutes worth of grinding with a handheld "dremel". I marked it with a sharpee and ground off a corner. Easy Easy Easy.
3.Yes. Yes they do match up. However if you own a drill, that's the only expensive tool required to Adapt your current intake. You will also need a hammer, a punch, a block of wood, and a set of tap and dies (10$-$20).
4.I'm not really sure, but I would advise getting one that would be recommended for the carbureted z24. There are several to choose from, and depending on the source may need to jetting adjustment. The Redline ones are all setup for this engine, and they have 3. There are two basic types of webers (they both have 2 barrells): 2-barrells, and progressives. "2-Barrells" open both barrells at once and transition between 2 sets of jets, the "idle jets" and the "main jets". The progressives operate on one of the two barrells up to about half throttle, then they open the other (usually larger barrell) for power.
The one I have is a "2-Barrell". It makes great power, but In my experience the progressives are smoother and give better mileage. I prefer the "2-barrell" because I have had such solid performance out of them, but I can still cruise (up to about 60mph) on the idle circuit if I'm trying to save some gas.
