What started as a little spreadsheet comparing the Triumph OHV 4 and the Triumph I6 for my project has fast become a honking spreadsheet comparing most engines of note I can think of. Here's a !!!error: Indecipherable SUB-paragraph formatting!!! if you fancy wasting some time :)

It's a little light on old-school American V8s, but it's tricky to find accurate data on those. All power figures should be net bhp, and all weights are 'fully dressed'.

If anyone has some info on engines not included, please put it in a reply and I'll add it on.

Holy smokes! You've gone off the deep end, and it's awesome!

OHHHHHHHH all it needs is bore and stroke, and I'm so very much good.

First and foremost, this is amazing.

Second, you won't be able to include old-school V8s if you are looking to use net HP. Unless you are talking about after the switch.

Are you planning on including gross hp?

Holy. Fucking. Hell.
Thank you very much. You've done this community an enormous favour.

You guys should split the SR20DET into S13 and S14/15. The S13 was 202HP@6000 using the smaller T25, the S14 ran up to 215HP@6000rpm with the T28 turbo. In the 99+ S15 they went to ball bearing T28s and made 245HP@6400 rpm. There are a lot of differences between the engines even though people lump them all together as SR20DETs.

I'm loving the list. Keep it going.

Some extra info on the Saab B202. 175 hp at 5 3 00 RPM, 201 torques at 3000 rpm. That'll fill out at least one blank ;)

EDIT, also it was used in the Classic 900, not the 9-3. The B204 was used for the NG900 and OG 9-3.

There are net figures for pre-1971 American engines out there.

Thanks :) all fixed now

I should probably add in a couple more Saab engines come to think about it...

With varying levels of accuracy. Not much that I'd trust if he wants a comprehensive, conclusive list.

Who dyno'd a stock LF7? Or LM1? What were the atmospheric conditions in the dyno cell? Oil fill? Every engine dyno session I've been at used headers. Etc, etc.

Thanks :) doing it now

Thanks man :) should be useful for anyone planning engine swaps. Getting weights right and such.

Casper > BiTurbo228 - Dr Frankenstein of Spitfires

I'm so happy to see a list of both engine performance stats AND weights. That was the hardest thing for me to research when I was picking an engine for my Z, and I'll undoubtedly need it again in the future.

I've got one that's got bore/stroke ratio which is probably quite useful. It's an old one with about a quarter of the engines though.

I'll see what I can do about finding them :)

Mopar Magnum 3.9: 239 cid. 180 hp @ 4400, 220 tq @ 3200. Max RPM 5500? Weight unk

Mopar Magnum 5.2: 318 cid. 230 hp @4400, 300 tq @ 3200. Max RPM 5500. Weight 495.

Mopar Magnum 5.9: 360 cid. 245 hp @ 4000, 335 tq @ 3250. Max RPM 5500. Weight 510

All three are naturally aspirated, cast block and cast heads. OHV. 16v for V8s, 12v for V6.

If I can find concrete numbers for the old V4 and 2-strokers, I'll send 'em your way

I should be able to get all specs, including weights, from my fellow club members

Same here. They're really difficult to find. Half on the info is 'this is the weight of a smallblock chevy...oh, without the intake or alternator, but with the clutch'.

Some of them I've managed to piece together from 'it's 12.5kg heavier than xxx engine', but most of the ones I've got seem to be solid.

Oh, and BMW engines are buggers to find. People keep quoting the factory parts manual, which lists them as shortblocks. Then you end up with people thinking a 3.0l cast-iron block I6 weighs only 120kg :)

Thanks man. Shall add them in in a sec.

Casper > BiTurbo228 - Dr Frankenstein of Spitfires

Exactly. It was driving me batty searching forums. Especially when I was comparing the F20C to the SR20DET. The 240SX people seem to think all the accessories and turbo on SR20DET are made of pixie dust and add no weight. The S2000 people seemed to think if you sneezed at an F20C it would make 400 HP NA.

Took me forever to get good data.

Forgot about uses: All three, Dakota and Ram (and vans). 5.2 and 5.9 - Durango and GC as well.

I could try to help

Yesss I do this all the time. Compare a a few cars, then it ends up comparing every car I can think of.
