197 head and throttle bodies

[samben]

I'm looking at building a new engine for my 197 track/sprint car, this engine will need to stay NA for class reasons.

The engine will be running throttle bodies.

I know of the front clearance issues with the 197 and the front brace, however I'm hoping to overcome that with a custom jobby.

My question is this; what are the differences between the 182/197 head with regards to direct to head bolt on throttle bodies?

Will a set of 182 bodies fit a 197 head?

Thanks
Sam

90% sure I'll be going K20 now, not wasting anymore money on the F4R. Too many limitations in its design.

182 bodies won't fit the mk3 head, different port position so not even an easy job really to re-drill the flange which is also different.

oh right that's interesting!! Will that be a first do you know?

Probably, not that these things bother me - it's just the best way to get decent NA power without needing a defined rebuild schedule with it!

I would love to see a K20 powered Clio! I had an EP3 Type R a few years ago and with bolt on breathing mods and a KPRO ECU and it wasn't far off 250bhp. You can get ~280-300bhp N/A with some wild cams and a few other bits which is mad when you think about it. That engine, tuned, in a Clio 197/200 chassis combined with a diff would be some serious porn to me haha.

The Honda K20 engines are a fantastic bit of engineering, they're also pretty bomb proof and can stand up to a lot of punishment before things start to fail. It's a shame the EU emission laws killed it off! Honda have always pushed the boundaries with N/A engines. Look at the EK9 Type R with the B16B engine - 185hp from a 1.6L N/A or the DC2 Integra B18C engine - 197 hp from a 1.8L N/A.

Then you've the Honda F20C engine in the S2000, until a few years ago it held the record for most bhp per liter output and it was just beaten by the Ferarri 458 in 2010 lol.
'The F20C held the record for producing the highest specific power output for any mass production naturally aspirated piston engine with 123.5HP/L until Ferrari began production of 458 Italia in 2010, which produces 124.5 HP/L. The F20C had been designed more than a decade ago, but it's still one of the highest output per liter and highest revving engines ever made. In recognition of its incredible power output, the Honda S2000's engine has won the International Engine of the Year category for 1.8 to 2.2 litre engines five times in its lifetime.'

Yes as you can tell, I'm a bit of a Honda fan boy on the sly! :d

Same, love Honda motors and tbh I should have bought an FN2, but yeah k20 in a mk3 would be porn!
I'd consider a K24 frank, but who knows...

Think we've raped this chaps thread anyway but I did answer the question at least lol!

 

[samben]

Questions answered!! Thanks! The k20 option has occurred to me too, like I said before I think that would cause problems with race/rally classes...

 

[samben]

Mainly due to engine being from a different manufacturer. But a k20 Clio would be gooooood

Only way to make a Clio fast and stay N / A is drop a k20/vtec lump in it. That would give you the ultimate track car imo. Still Beable to out corner most other cars but you'd have the extra straight line speed the Clio engine can not offer
