Hi, I'm new to this forum and my name is Andrew.

I have just bought a 1st gen crx and intent to turn it into a race car. no rice for me!

I currently own a 2001 mazda protege5 which is NA and i have a best 1/4 mile with it at 14.860 @ 92mph (stock is apx 16.5). I have previously owned a 6th gen civic too.

i was planning on totally stripping the crx and getting as much weight out of it as possible. more the better. the car will then be fitted with a roll cage. hope to get the car weight down to apx 700kg without the roll cage (880kg stock right?)

i will do an engine swap and put in a f20b, ITB's, custom cams, 4-1 tuned header and a standalone ems (10000rpm rev limit on the cards)


first question i was wanting to know is about vtec. i can get an EMS (microtech) quite cheap as i intend to run the car without the stock ecu in place. is VTEC controled by a soleniod or is it something else? the reason i'm thinking microtech is that i have that ecu in my protege5 and it's so simple to tune.

thanks, and this is a great forum. lots of fantastic info here.

F20b? why not b20/wb16head? the vtec is just controlled by a solenoid

 

also since its your first post the search button in the top coner is your friend

My thoughts exactly........and *search*. Welcome to H-T

 

i've been using the search options a lot and that's why i decided on the f20b.

in australia it's cheaper to get than a b engine. 200hp to begin with soudns good too.

what advantages would a b20/b16head have over a f20b? i'm not planning to swap pistons or rods at the moment, and everything else f20b is basically h22a right?

I'm wanting to stay NA (hence the itb's) and looking for (only) 250whp.

cool about the solenoid. great to know. makes controling it very very easy. on my protege5 we have a variable intake manifold that's controlled by a solenoid and the ems just tells it to open and close thanks to a relay.

One huge difference is the b16/20 there are parts for days. Not so for f20.

 

yeah that's one thing i do know.

still, the h22a has a good amount of support...anything has got to be better than my protege5 (all my own custom work basically)
