I have got together the basics for a new motor for my sedan: A15, scorcher electronic distributor, twin 40mm dellorto's, high compression oval port head. My goal is for the Datto to beat my Honda Accord Euro manual in street use. As a guide the Honda is supposed to do about low to mid 8's for 0-100 kph & high 15's for 0-400m. I reckon I need about 120+ flywheel BHP to allow for me only having a 4 speed & the wide spread of the Honda's power. What do you all think.

What, no opinions? How about what will it take to beat my Honda (no, not a stick). And no, I am not talking about street racing, just a quick blast away from the lights & up to about 80 kph. Their is nothing worse than being beaten away from the lights by a family sedan or even worse a falcadore repmobile (auto).

0-100kph (0-60mph) in 8 seconds is fairly quick (it's what V8s did in the 60s).

My guess is no, the Accord will be quicker than your A15.

Power-to-weight:

100hp
--
1700 lbs

vs

150 hp
--
2500 lbs

The Accord would have the edge. What year Accord is it, and which engine?

I disagree, your A15 1200 will be able to beat a Honda anyday if you build it right. You'll probably have to do more than dual carbs, higher compression, and an electronic ignition however. You need a bigger cam to eat the fuel up on those carbs, also you need headers and a good exhaust to let it breathe out all you're putting in. You should look into a lightweight flywheel and headwork also.

My A15 had stock compression but a .229 duration cam (@.050" lift), rebuilt and balanced rotating assembly, alloy flywheel, dual Dellortos, Nismo header, oversize Si valves w/dual springs, ported and polished head, electronic ignition, 1.5:1 Nismo rocker arms, and electronic fans and fuel pump, and it did about those times (high 15's in the quarter mile, 0-100 kmh in about 7 seconds). I say go for it, it'll be way more fun than your Honda!

personally I would like to see same era cars compared eg 74 EB1 civic that has had a Yoshimura kit put in it.
We did one up for a customer all we did was o/s pistons,twin carbs,exhaust and I dont think we did any porting and man that phucking thing went like dog shot in the ass s.
To be realistic the A series engine is a copy of the Pomy A series which gos back to the fifties.

thoughs acoords haul!!! not legal but some NOS has put many situations like this to rest.

Sorry to ddgonzal & others not in Oz, Its a Acura TSX in the US. It runs a 140kw 2.4 4cyl with a 6 speed manual and weighs about 1400 kg. Thanks AFRacer, I was interested to see the 7 sec 0-100kph time as that is more important to me than quarter mile times. Probably even more important is 0 - 60kph. I was considering running an SR20 N/A but it looks like I can achieve what I want with the A15 without huge expense & not spoil the handling with extra weight.

Yep those 1 generation honda civics are good stuff ade. i am after a cheap one if anyone has one

I found this web site http://www.web-cars.com/math/qtr_mile.html I don't know how accurate it is but for a rough guide I think could help I am worried about your 4 speed though, I suspct they could be made of plastic or some kind of soft cheese

Hahahaha, I just checked that site there and you need over 455,000 hp to get a 1 second 1/4 mile time in a 120y coupe
