Did any generation prelude vtec (H22) come with the dual runner intake manifold similar to the integra GSRs? I could have swore i read it somewhere, but maybe i just dreamt it?

 

all usdm h22's have dual intake runners, so do h23's and my 89 lude with a b20a5 has dual intake runners too

 

what he said

 

all of them

 

Ok, so i wasnt dreaming, do they work on the same/similar system as the GSR in that the secondary runners open at a preset RPM? And maybe this question is for another forum, but does anyone know if a JDM 1994 Prelude SiVTEC ECU (OBDI) will work in a 1994 OBDI GSR as they both have the same plug lay out? And one last question, what ECU came in the 1993/4 Prelude SiVTEC?

 

yep, works same way.

 

the ECU was a P13

 

sure it works, but there is no advantage to running it...

Like prelude people have to run P72 for Hondata

 

I'm going for the P28 and pulling the butterflies/praying that Skunk2 gets off their collective *** soon.

 

I have just switched in CTR cams to my JDM Si Integra and so want to raise the x-over point, i know where i can get a 93 prelude ECU for free and so was going to use it as it has the higher vtec x-over point and also controls the secondaries
