Under 2 litre ipra kar options

[hrd]

I think an S13 with a very well built CA18DE stroked to 2.0ltr or an SR20VE would be a good option but the reality is nothing can match a K20 powered Civic.

only 1 person has even tried with an NA S13 AFAIK - its going alright

Nah, Stupid rules make you use same configuration so It must run an Inline 6cyl engine.
RB20DE would be in a world of Pain as their heavy torqueless pigs.

I noticed GXi R32 the fudgepacker model has a ca18i!. R32 has huge aftermarket leftovers these days.
A qr20dd would be possible. In the US theres a QR20DE with modded full counterweight sr20 crank.
The DD has the direct injection. Rod stroke ratio is way better than any SR. 89mm bores x 80.3 stroke.
10kg lighter and heads outflow the sr20de. Rods are long a flimsy things first thing to tackle.

only the GTS, GTS4 and GTS-T model R32's are eligible for IPRA under the approved models list. GT-R is eligible under Group A homologation. All of which were straight 6's. Therefore only straight 6's can be used.

Thanks for the heads up, Its a shame as I didnt think the s13 was campaigned in their day yet its allowed?
The more cheap attainable cars that are allowed the more chance to see this series healthy in tougher times to come. Currently there are many selling their weekend racers and projects.

Dave is a bloody good steerer - he'd easily be in the top 10% of IP drivers.

It's taken a lot more effort than most would know for him to get that car at the pointy end. A plug and play Civic is a far cheaper and better option. Dave is just a Datto fanatic, hence his persistance...

Im only In The Datsun Sunny GTiR cause Im a Datsun fanatic.
Civic is a great package and I believe an EG with a K24 with 2.6 kit could be an outrite car in the right hands.

If over 2ltrs and being Datto Bias how about an S13 with 2.6 KA24DE?

Great idea in theory, but then you are head to head with the rotors and it would still be sorely lacking in power to weight.

well considering people have got over 300rwhp out of sr24ve's and the engine is a little lighter I think its a poor option. Although the torque from the pos ka would be decent

Ive been corrected the SCCA GT3 KA24E engines roughly cost $9.5K to build
300+hp @ the engine. Though Brian Crower 2.6 cranks where not approved.

Top RX7s are about 250rwhp on honest Dynos inc the Tander car and within 1000kg race weight and have 30+ years R+D but I believe the 90s Civics with a big K engine can match them.

Not sure if the KA engine is avalible in an IP eligible vehical? If not then we can not use them.

[Supashake]

IP eligible cars only so not Pathfinders etc.
