S2000 engine in a 7?
Discussion
Was thinking about a 4AGE Toyota engine for the Luego when in arrives soon but I got wind of a few people wacking Honda S2000 engines in 7s without much fuss. Furthermore, I see a few low mileage ones knocking around for just over 3k.
How hard does everyone think it will be to drop one of these units in a 7 chassis? The thought of 250 horse in a 7 just makes my knees go weak!

Don't Honda engines run 'backwards'?
Anyway, I would highly recommend the 4AG route because -
a. I race a RWD Corolla with one.
b. I have a 168BHP engine and/or Quaife gear kitted gearbox if you are interested.
The 4AG is a good engine and very reliable if kept below 180BHP and 8500RPM. You also have the option of 5 valves per cylinder but only worth bothering with if you aren't planning any serious tuning.

But the latest ones, including the S2000 lump, spin correctly 
I've heard it can be difficult to get the ECU working correctly to enable the VTEC cams, as the wiring is a bit of a nightmare. It is do-able though._VTEC_ said:

Have been for a ride around Anglesey in one...well, a Westy. Bookatrack built and ran it for a bit...don't know where it is now. Seemed pretty well sorted.
I have a good friend who is building a Dax with an S2000 engine..... he has done masses of research so would be a very good person to speak to.
Regarding the engine, I thought that the S2000 ran in reverse to normal. However I am assured it is the Civic Type R's that are like this and that the S2000 runs as normal so a sierra diff can be used.

If I recall, it was all of the "old" (e.g. B-series and H-series) Honda engines that ran the wrong way...for a fwd car, anyway. Honda always used to make their own gearboxes, and because of engine rotation these were on the "wrong" side...hence they had to make their own, no off-the-shelf ones existed.
(One rumour is the engine rotation came about because that way the oil pickup would be on the correct (i.e. left-hand) side for fast right-hand corners on-track, resisting oil-surge a lot better than if the other way around. Personally I think this is unlikely, but it's a nice story!!!
) But they designed the K-series (current Civic) to be the "right" way around as they were now outsourcing gearboxes like most other mfrs.
Not sure how the F-series in the S2000 fits into this, but it's been transplanted successfully, so would be surprised if it's a big issue.
FABULOUS ENGINE!
aparently honda have had NO unit failures on this engine so far! - impressive if it's true!. it's also the highest specific output of any production normally aspirated engine at the mo.
The real gem, though, is the gearbox. I took a couple of S2000s out for a test drive a while ago, and it really is the sweetest gearbox I've ever driven!
good luck with the transplant! If it works well let us all know! - It might tempt me to ditch my zetec!

The idea came about as me and the old man were looking at getting a competition tuned 2.0 Zetec (as well as the 4AG). But this would mean getting re-builds quite often which would grate with us. Then a little bird suggested the S2000 engine which is rock-solid and very powerful not to mention light. Added to the fact that we could source a low mileage one with gearbox for pittance really. This could well the one for us.

When you say pittance, exactly how much?
Given the rareity of the S2000 i would be surprised to see and engine and box around for less then £5k!!!
Agreed its a good engine for a lightweight car and can be supercharged by mugen to give 300+bhp
Civic Type R engine might be a cheaper option
The S2000's engine was the first Honda engine that spins the conventional way--at least as far as I know. Since then, the four cylinder 2.0 l engines in the Civic and Honda Integra (Acura RSX in the US) and their stroked counterpart, the 2.4 l engine in the Honda Accord (Acura TSX), also spin in the "correct" direction.
The direction is only an issue if something other than the stock Honda transmission is to be used, but I have heard of a Lotus 23 replica (IIRC) that used an old, backward spinning Honda engine mated to a VW tranny. I'd imagine that they'd place the ring gear on the other side of the diff to keep the direction of the wheels correct, but what I always wondered in such an application was if spinning the tranny backwards would be a problem. Apparently, someone thought not.
Also, here's the link for a Seven type of car built in Texas. It uses the S2000 engine and transmission.

engine, box, diff, prop, shafts, loom ecu etc.... all for £3k.
SOLD! I'll take two!
Me too!!! Where from?
Yeah where, I'm looking for a Civic Type r engine box etc. Wonder if they have one!
Do you need a signal simulator box to get the ecu working correctly? For vehicle speed etc usually coming from ABS ecu, body computer etc.
I looked to do this in 2000 the engine spin clockwise, correctly, it is a big lump and 2" taller than the Kseries ( Rover ) the engine id is F20c, it does have a problem with scored no 3 cyc bores
THe latest Honda civic type is a K20a it is very similar but not the same as the F20c, but the head is flowed to produce 268bhp before porting is required, it produces a lot more torque than the F20c and is a better engine.
It also has lots of trick parts being produced for it asked Simon Scuffham a PH'er, TB , cams dry sumps, etc..
It is the engine to go for
