Signed up to do a bit of research into mapping standard ecu systems, and thought id post up my little toy... Don't be to harsh... its a track car on a budget!

(Blatently Copy Pasted from another forum!!!)

Thought i might post up a few pics of my current toy... 1991 Honda City PGM-FI CZi :P

It's a 1.3 SOHC 16v, 100bhp (book power) and 680kg (again book weight).

The CZi came with a Cussco LSD as standard, and A/C :P

According to Honda only 142 were imported to the UK...

I'll keep this thread updated with the progress :)







Well from finally getting it out on track, i know now...

A) It's still factory limited to 110mph

B) It's AWESOME out of the corners (pushing 90% of big power stuff in the bends)

C) It REALLY looses out on the straights

D) Corners like its on rails, but body roll is silly!!!

The answer???

Coilovers and BOOOOOOOOOOOST :P







Weighed it this morning...

Partially stripped, half tank of petrol

672kilos







Also now decided it doesnt need the civic brakes... it was locking up at combe, with its lack of weight i don't think big brakes will do anything.

Just going to replace it with some decent spec standards... if i can find any...






Just ordered a short shifter from america... £15 including taxes... guess we'll see






Sooooo... after the i bodged the standard rad fan onto a civic rad (which is a good 3 inches bigger both ways) the fan sliced through the bottom hose...

Went for a walk over to forge motor sport (litterly accross the road from me) and traded £80 for this little lot...

Image

Normal retail would have been £130 plus VAT... BARGIN

Also got another civic rad from work and mounted a 9 inch slimlie fan to it...

Image

So now hopfully the cooling system is sorted...

Quickshift also fitted, makes a HUGE difference!

Next??? Blue h/t leads to match the pipes :lol:






More progress today... bye bye A/C

Image

Image

Good 15kg there i think :lol:






Dash has come out (only so i can sort out the aweful wiring) as has the carpet and most of the sound deadening

Also got round to fitting the OMP bonnet pins, so now i can chop the slam panel off to make way for the BOOOOST





Ahhhhhh... Herroooo...

Image






After me and Alex had a quick session between rain showers yesterday we came up with this...

Image

Image

Just a rough idea of the layout... oil cooler sat in play in the wing and turbo roughly where it will sit (you'll be able to see it through the bumper... PIMP)

Playing with a few intercoolers later :D






Booost...

Image

Won't be quite so sticky outy :P





Nothing much happening at the moment...

Spun the impellor housing round so the outlet goes stright up...
Image

Also welded the internal wastegate shut...
Image

Left to do... Fabricate a downpipe, pipe in the internal fuel tank, buy and work out all boost piping, oh, and fit the new engine :P

Doner Number 2... 1.6 VTEC

Image

By using the 1.5 block and the 1.6 head, Compression ratio is brought down to approx 8.8:1...

FYI, the 1.6L sohc vtec heads have a smaller combustion chamber than the 1.5L non vtec heads. The combination you have will yield higher compression not lower.
