What kind of truck do you have? I've even seen L28s squeezed in to 510s before, so I guess anything is possible.


Anyway, here is some carb goodness:

FCR set up on an L28 (2.9l):



I believe these are FCR carbs on an L28 (the description says FCR, but they look different than other FCRs that i've seen, so I dunno):



This is a cool video of a bunch of different carb set ups on 4age AE86s. The MSR carbs look and sound awesome, but i've never heard of them before. FCRs are awesome as always, the expression on the guys face after driving them is classic (5:30):



I'm not sure why FCRs always rattle at idle....

I also just found this:

Oh whoops haha. Yea an L28 would be much more fun than the L16. My first car was a 510 with an L20 with dual weber carbs and a dog leg 5 speed. That car was so fun.


Now that's what I'm talking about, old school is best school. Do you have any info on that set up? Internal mods or power numbers? Looks like RB26 but I can't tell what carbs.

gear it's a RB25DE with RB26 valve covers. I can't remember what the HP numbers were it's been a while. I don't remember where he got the ITB's(no carbs)from but he is running a Microtech stand alone.

Ah gotcha. Now that I look closer I can see that it's an ITB set up.

Bro if you're trying to replicate a S20 get a RB20DET you keep the oil squirters... not that they matter.

do 12.5:1 like you wanted. go ITB tripple carb's. and you can keep the ecu use it for ignition.

the RB25 will never replicate a legit S20 that was used in the race car hakosuka. sure the displacement is nice but it's not the same experience as the little S20.

THE LD28 YES A DIESEL version of the L28 I believe a RB diesel as well sohc. i believe Z24 came in diesel.

and yes the US DID get a LD28. it ran 22.1 or 20.1

I'm not trying to replicate the performance of the S20, I'm really just looking to replicate the LOOK of the S20. After driving my miata for a while i'm really missing the torque of my old RB25.

About using the ECU for ignition; does anyone know if I would be able to keep a rev limiter using the ECU to cut spark at the desired RPM? I would be a little worried to run a motor without any form of rev limiting.

LOL... Randomly searching came across krome's car... though of this thread...

As for your question I think you can but I think you can use something like Nistune or you can use something simple like a Bee-r rev limiter

That car is cool. It's like half of what I am thinking. I would like to see what kind of power it would make with a high comp bottom end.

Another way to increase compression that I was reading about on miata forums is shaving the head down. Has anyone heard of this done with RBs?

EvilRB

I think that is exactly what one of the engines that rocky auto did with their 25/ head on a 30 block combo was... I'd have to find it. you should try asking the guys on JNC these questions they might have a better insight...

I know the rocky auto carbon Z with the RB30 block is carbureted, I dunno about any others.

I've never checked out the JNC forum, I should've looked there haha. I'll search there for a while.
