to the forum,
thanks for your help, I'm involved with a new formula company and we will be using the Vtech or Ztech motor platform for our base platform. I'm searching for a reliable motor source. If possible it would be great to get a list of people who people would recommend with some contact info.
We are excited to learn more from this forum, and hope to find sombody soon to help us develope the project.
cheers,

honda k series or f series(2000)
honda all the way.

 

i dont know if this is a dumb question, but what the hell is ztech?

 

ford focus

 

one of the reasons we wanted Z tech was that we have Cosworth offering us Full Alum blocks to use.

 

i just love honda thats all.
i wondering what the weight difference would be between the two blocks.
also what rules do you have to follow during the build?

 

If you are operating under a strict budget, I would consider the offer from Cosworth. From a business standpoint, free replacement blocks is hard to refuse, even if it means sacraficing maximum power potential by using only the Ford Ztech platform.

However, from a power and reliability perspective, there are many K-series engines making an excess of 140bhp per liter. A OEM TSX 2.4L K24 block and head, with cams and a good header/intake manifold will make 250-270whp on the right tune, thats about 300bhp, not too shabby for an all OEM bottom end.

 

Don't forget the modified S2000 oil pump that makes the K24 motor really reliable.

 

when you say ztec, would you be reffering to the 2.3L verison that came in the focus one year or the 2 liter version? is there a displacement rule?

is there a spec cam? TB size? stock ports? these are all things that might help in deciding a platform.

if youre seeking an engine builder id say don flores. he is a ******* ******* but he has been building engines since henry ford was still shitting his pants.

i think vtec is pretty useless for a formula-type racing series, id probably run a straight non-vtec element engine (best flowing K head) with a large cam and make sure the tranny kept the engine in the sweet spot of that cam.

Yeah, I agree vtec is not great for road racing, but I-vtec thats a different ball game especially with a custom grind for midrange torque.

to the forum,
we are limited to C sport rules, for international racing but we have started our own serise to help support the manyy other forumla cars which where build to run in classes which can't support them. we are limiting the motors to 2.0L with dry sump, intakes and headers with a good tune we hope to get around 200hp. remember our cars weigh under 600lbs.

 

Based on 2.0L limit, K20A is the way to go.

600 lbs, damn those are going to be some very very fast cars.

ok. so youre starting your own series. and you want to know what engine platform would be best to regulate your series' competitors to using?

but yes, a k20a2 will do 200whp with what you mentioned. i dont think the 2 liter ford will without more work. a b20b wont.

the 2 liter VW engine surer than **** will make 300whp, but its boosted.

are you asking for a contract engine builder to build "X" amount of these spec engines for you? maybe jsut for test and tune?

 

The K20A, without doing much work, can support 260-280bhp. If your only restrictions are displacement, you can really make some serious power and still maintain reliability.

The problem I see, is that Cosworth makes its living by supplying race teams with engines, so that the teams can concentrate on the other aspects of the car/race, if you try to outperform the Cosworth engines, they might pressure the sanctioning body to restrict intake diameters, which will really hurt the Honda engines because of their operating revv range.

BTW What sanctioning body are you using as a base? Formula Ford? If this is a serious series with a good amount of support from chassis builders and tire suppliers, you might be able to get Honda on the ball. Honda N.A. is trying to expand their engine production into different racing series, they are already the sole engine supplier for IRL.

 

You are limited to 2.0 liters, because as was suggested eariler if you aren't, why not just use the Cosworth 2.3 ztec based motor? I think its 260 crank, correct? Will probably be very reliable because it isn't too stressed at that displacement.

 

is it just me or does 200 whp out of a 2L vtec seem like a real walk in the park? did i miss some restriction that everyone else knows about?

what rpm band will it run and how long must each motor last?

 

C Sports rules in SCCA are currently a max of 1622 CC's. We converted a Ralt RT-5 to a B-16 engine. A Formula Ford weigh's 930 lbs. A F Atlantic is 1250 min with driver. A D Sports Racer with a bike engine and gearbox may get to 7-800 lbs. A full dressed 2.0 Honda without gearbox is over 200.

 

maybe he meant 600 kg.
