Might buy gl 88'

[nicolatatay]

i was going to buy an old 88' model gl, its done 250,000km
D15B1 1.5 8V [acronym:d4ff0c72b2="Single Overhead Cam"]SOHC[/acronym:d4ff0c72b2] PGM-FI 1493 70hp@5500rpm 83tq@3000rpm 88-?? Civic

should i bother buying or save up and get a later model?

[mytoycivic]

you sure its 8 valve?
my 88 GL is 16 valve w/ 72 (?) Kws and something like120NM torque...
it is a great car for me...gets me from A-B
good for conversions later on too (my plans :))
how much you looking at for buying it?
BTW i will have spares for the D15b when i do my conversion early next yr so if u buy
it you can get some spares from me if u want
:D

[egSi]

hmm yeah man get the old school like mytoy and drop in an efi D series for cheap gains :D

[Setanta]

Ok, I'm biased, but go for it. They are a decent little beast and dropping in a SOHC VTEC motor or ZC is a very nice performance mod. Don't forget to ensure you get things like an EFi pump and surge tank, not to mention an ECU to match the motor. As I understand it, you can use your original gearbox with either of the above options.

BTW: It's a 16 valve SOHC D15 and is rated at 100ps (98bhp), the 70bhp you are quoted is off the USDM spec dual-point 1500. The aussie spec is twin-carb, the US version is dual point fuel injection (DX) or multipoint fuel injection (Si). We got the power of their top motor (Si) in the twin-carb GL. Don't use US manuals to service the engine, use UK or Aussie ones. Gregorys, Haynes etc all give out the wrong specs on the motor.

Long live the 4th gen Civic... lets make them the cult car they are in the US :)

Yeah man, go the ED civics! Drop in a d16 n ull be laughing...now i got a d15 n even im happy with that...took on a 92 prelude today...i wasnt fair behind...infact i dont fink he was pulling away that well...he probably lost a piston or sumtin :p

hahahaha do some mods man, those d15s own!!!! :D

[rly1]

haha.. yeah!!
I'm a ED civic too..haha u will love it

[mytoycivic]

one day EDs will own :D (i hope :()

[Toby]

Get an ED and later on drop in a B16 or B18 :thumbsup:
All you need is one of these:

yeh w000t nother ED to the family

[dundas]

Hey i also got a ED, its a great lil car but why does it feel 10X slower than the Manual version...obviously mine is AUTO but yeah.. it shouldnt feel THAT much SLOWER should it??? what could be wrong with it??? ohh would a cat which has terribly detirorated (very noisey) hinder the performance of it? ^_^

[[ slayer ]]

yeh. go for it dude. as others have mentioned it provides plenty of potential with a new motor :)

[mytoycivic]

yeh w000t nother ED to the family

i told you guys EDs will own :D

um...auto...c r a p p e r f o r m a n c e ! ! !
get a manual...

[Setanta]

Toss the auto - while you can get up and boogie by shifting it manually, the D15 doesn't really shine without a spanish box (manuel ;) ).

[mytoycivic]

*agrees* you may get away with auto in a D16 or B18 or something like that but not in D15 :D believe me i have a manual ED and it is slow in itself! hence the conversion plans

[QUOTE=mytoycivicbelieve me i have a manual ED and it is slow in itself![/QUOTE]

Mmm...no offence but speak for urself bro...
the d15 in ma hatch aint dat bad...or maybe its the weight diff? I darnoz but the d15 in my 89 ed hatch seems like a rocket...esp for its age...maybe your compression or sumtin aint too great...
like as i said in one of my other posts, i was basically even wiv a 92 prelude, if not just losing a tiny bit but he wasnt pulling away. SSS yeah, that pulls away after second gear about 4000 but still not that great of a lose, maybe 1 n half car lengths by about 120km/h. The d15 engine is pretty good. I reckon with sum nice cams, extractors, zorst system n chip, it could probably even wiv a SSS.

[Setanta]

Double post and I can't work out the delete option :(

[Setanta]

The D15 in an ED6 Hatch is actually a good combo. The engine is 100ps but in a 920 kilo car, the sedan is heavier than the hatch - which I have been led to believe, is only marginally lighter than my EF9 which weighs in at 1030kilos. BTW - don't trust the weights on your rego sheets, they're inaccurate - I put my old ED6 over a weighbridge and found it was heavier than the the paperwork... then again, the RTA also had it down as a coupe. Go figure.

[mytoycivic]

the RTA also had it down as a coupe. Go figure.

yeh prob to charge more money for a 'sports car'....

yeh my civ aint as slow as i say...but i doubt urs is like a rocket!!!
i mean when i say slow...i just mean its not as quick as i WANT it!!! but for a 1.5L they rock...i am not kiddin they are prob one of the best-keeping 1.5's on the market in late 80's/early 90's

[dundas]

haha i see-- might go buy a ED later in my life just for kicks ahahah--- ps its my Mummies car ahahah--- but it feels sooo sloooow-- yeah i do agree da manual (aka spanish version to others) kicks ass to the MAXXXX

as you can see by my garage post. the ED is a great a-b car, not much else though unfortunateky.

heres the link : http://www.ozhonda.com/forum/vbgarage.php?do=view&id=35

[Setanta]

Thats why you want an EF... or to EF-ise the ED :)

[Setanta]

BTW - 54.7 is a decent output - with drivetrain loss it works out nicely - my EF9 hit 79.8 on its first run and 82.3 on the last run on the dyno with a new catalytic convertor (old one was choked). 54KW is what I got on my modified 1226cc 1st gen Civic with mods though... before I bored and stroked it... and the 1st gen was a couple of hundred kilos lighter than the ED :D

[Rowie]

you may have had a colder day when you dyno'd the 1st gen pete :P Was dyno'd at Dyno Daves :D

[mojo the flashy monkey]

lol wana buy my 88 ed it gows rly hard :P lol ask faijai :Psounds good 2 :P

[Rowie]

one other question, what do you estimate the drivetrain loss percentage is with the ED pete?

Ive been calculating about 15% to work out the flywheel figure.

[Setanta]

Ummm... it was pretty extensively modified. 1226 block, balanced and blueprinted. Ported and shaved head bumping compression to 10.5:1. 2x dual throttle 35mm sidedraft Dell Orto Carbs (think mini webbers), Mugen R1 cam, 4-2-1 custom header (hand built). Electronic fuel pump, 1500 radiator, 1 3/4 inch exhaust running through a series of hot dog mufflers (yes it was loud). 100bhp is well within the possibilities with this setup. The '74 RS1200 did 70bhp @ the flywheel and was a much lesser setup. When the motor was originally built, it was bolt ons - when I bought it, I had it torn down and rebuilt (didn't help that I blew a head gasket at 7000rpm). When I took the motor out after its 4th rebuild when I used an EN1 crank and rods to stretch displacement out to 1335cc and bored it out to 73mm, it came on a lot stronger.

For its capacity, it was a torquey motor, torque steering in first, second and third (in a 660kg body). It would out-run a 2G CRX and once scared the bejesus out of a V8ute that bogged down off the line. McChook's dad had an even better example that left mine for dead - full mugen race options including the quad throttle bodies (Keihin Carbs) and a dry sump. Closer to R3 spec I think but bored and stroked as well.

Never underestimate a 1G - they are damn quick when modded properly and a D15 powered 4G would never hold a candle to them... in fact, my gut instinct is that the 1G I owned wouldn't be a slouch compared to my SiR - certainly not as fast, but not too bad.

[Setanta]

one other question, what do you estimate the drivetrain loss percentage is with the ED pete?

Ive been calculating about 15% to work out the flywheel figure.

Rowie: I don't believe 15%, I think it's closer to 20% myself and that doesn't include the potential for another 5-10% on power steering and aircon belts.

I quoted an 82kw figure for my EF9 - which works out to be 110hp (not bhp) My car is rated at 160ps or 160hp or 158bhp (someone check my maths please).

20% of 160ps is 32 ps (hp). Therefore theory holds that I should be getting 160-32 = 128ps. However, there are other issues such as drivetrain loss doesn't take into account belts (I have AC and PS). Removing the belts (inc alternator) netted me 86kw or 115ps. That left me with 13ps unaccounted for.

Now this is where I am getting into murky territory.

#1 The motor is 14 years old with 276+K kms on it - I don't expect it to be making 160ps anymore.

#2 Final drive is 1.103:1 ratio, not 1:1 which someone tried to explain might be an issue - I didn't try to understand. :confused:

Like I said, I'm largely ignorant on the dynamics, but 2 stock EK4 VTiRs made the same figures before they were modded. On the original run when I got 79.8, modded EK4s were getting 6-14kw more.

Your D15 is rated at 100ps - assuming it's the same as the JDM one in the XT25 - which it is if we look at the motor specs, comp ratio etc. Your figures are close to that too if you use 20%, but not 15% and then add in the extra ancilleries.

I wish I knew more about dynos - all I know is that they are tuning tools and aren't particularly useful to measure output other than comparitively.

If anyone wants to point out issues with my discussion on this, I'd be interested in being educated :)
