Well after a couple of weeks of talking to different people I'm still undecided.

'90 CRX SiR with a B16A obviously with 230,000km on the clock at 97.3kW @ the wheels

My ultimate goal is 150kW @ the wheels which isnt an imposible target really.

150kW @ wheels staying N/A
but the main thing I want is for the motor to rev quickly and easily. Factory not really a huge difference but with new valve train and cams etc etc

Ideas, opinions and most impotant of all personal experinces welcome...

The last thing. B16 and B18 mounts are the same yes?

Thanks

edit:: were also working on changing the ECU to OBD1 so we can chip it to use with the current engine for now...

 

I like the idea of 1.8L over 1.6, I like the idea of the B16a head over the gsr head, so I would have to say Type-R as it has the best of the best of both worlds, BUT at high costs. yes the mounts are all the same. but realistically you could go with a sir-II second gen B16A (170hp or whatever that turns into in kW heh) and OBD-1 and hyrdo transmission, etc, etc....

 

I would stay with the b16a since you already have it..Just do alot of headwork and tune it to the max and maybe even get an individual throttle body setup

 

regardless if i go for b18 or b16 the old engine will be sold

 

So even if you go b16a you're gonna sell your b16 and then buy another..?? Why waist money..

 

ill tell you what ive been told a thousand times... theres no replacement for displacement

 

GSR....Got a modded one in my Ef9 and a stock one in my DA even in stock form I love it. 1.8 all day! With a decent flywheel, nice cams and valvesprings, and port polish if you please you can make nice power. BTW you don't need to rev the **** out of a motor to make power. Have fun whatever you decide to do....

 

I dont see a point in modifying an old tired motor when you can modify a refreshed one really...

 

your gonna be pretty much rebuilding any motor you get so why not rebuild urs instead of buying a new one just to rebuild it anyways

 

because it will mean i wont be able to drive the car while its being rebuilt....
