Yo Ozvasquez no updates? Let see how it went

I don't think the competition is a drag race.

The competition will be tough since streetability, and all out HP numbers are key. This would be a pain in the ***, but has anyone suggested a huge streetport combined with a semi PP? There needs to be a way of getting good port volume but minimizing exhaust/intake overlap for good streetability (lower idle & slightly quieter).

I would say the rotary would take it if you were building race only motors. Getting the exhaust to flow sufficiently while not getting pulled over everyday will be the issue.

Good luck!

the other car never made to the assembly line. the guy broke his ankle in a car accident. this happened about 3 months ago. so i slowed down and started a turbo build for the starlet.

awwww. he knew he would get owned

too bad, sucks to break your ankle

my recent experience with the K-honda engine was the 25 hours of thunderhill

ALL of the K motors failed, ALL of the backups failed, except the spoon car. this is something like 8 out of 9 engines failed.

the rotaries i think all finished

so does the K24 make BIG power? yes. can it make power for very long? no

not only did padilla make more power,he also had a minumum weight disadvantage. that is the only way nhra could get the honda's to be comptetive.

wow i did not know the rotary boys hated hondas as much or more than us nissan boys.... lol thats awesome

I'm trying to remember if it was SonicRat or JRat who was putting down 600 whp on a stock internal, street ported 13b.

iTrader: (3)

you may be talking about JRat, i think i remember that. however, you need to remember these guys were planning to run N/A, not turbo.

I did read the rules and didn't see anything about turbo, I figured that would be included in "any mod to engines".

um thread title??? both na????

D'oh! My bad. In that case yeah, you're probably stuck. The closest you would get probably is using Rx8 rotors, balancing everything perfectly and then running 12,000 rpms or so. You'd still be doing good to get to 250hp though.

peejay

RX-8 rotors aren't all that they are cracked up to be.

A streetable bridge port shouldn't have trouble making 250hp... at the wheels. Plenty people make close to that at the crank with a street port. No crazy RPM necessary.

id agree with u on dyno numbers...b ut as far as 1/4 mile times i think the 13b could stomp it.. tkaes a **** ton to make a civic hook

Liborek

Do you really think that 13B cannot make more?

idk...never torn one open to try... but a garage build with not going pp, i would put dyno money on the honda. although i love 13b's soooo much more.

Liborek

It seems that Honda engines are bolt-on power to certain level, but don´t forget that K series aren´t cheap at first place. Nothing like that for rotary, all must be done by trial and error, experienced people aren´t going to let cat out of the bag
but it can be done with stock internals

Just for fun, what do you think, how much HP has above car?

peejay

Are you kidding? There is a WEALTH of information on porting, clearancing, reliability mods, and tuning. The only secrets are with the people who raised the bar and got 105% and don't want to divulge how they got that extra 5%.

I'm having a hard time just trying to find out what timing I should start with for my VW/Audi product. If it was a rotary, and I asked, I'd get about 12 answers in two days and 11 of them would be the same.

And yeah... I could build a kickass rotary for less than a pair of camshafts for a K-series would cost. And Honda engines have VTEC so they idle smooth, very boring to drive in the city. Might as well be a Camry.

Liborek

****, I didn´t mean it in this way... I agree with you on every point. All the info is available, but when it comes to port timing and intake/exhaust tuning, most people get confused

Maybe because people are more familiar with one most usual geometry of rotary(13B) than immense variation of piston engines...

This is the point what I tried to say, but my english isn´t good enough to clear up what I have in mind
I think many people ignore basic fundamentals when building wankel engines or any other ICE engine... I grow up on 2-strokes and learned one basic thing, one modification isn´t going to work well without many others....
I´m sure you have it very well covered, 100 MPH in 13B street port at given weight is much success. Its sad when people who invested a lot of money into their fully build N/A engines with very agressive porting struggles to run 100+ MPH in much lighter cars

yeah its so easy with the honda, its all chipped ecu's so you start with stock, advance it, see that it doesn't add any power, and either go back to stock, or leave it there and let the engine detonate itself to death....

one of our race buddies has an immaculate TSX, and those cams are EXPENSIVE, and um might make the valves fall out of the head...

supras With 2jz they make high hp numbers but dont run hard at all intill like 650hp. k20s are overrated I been there done that build that 13b na dont put it in a Starlet put it in a 1st gen . give it a nice port job do little things here and there .do some rear end work to the 1st gen put some BFG G-Forces on it or some Nitto 555 if you have to run street tires you need to hook up nice that will be the key.hooking up change the gears in the back and you wil mop that Hondas *** all over the track . and thats a FACT ....

what about having those new aluminum rotors they have been testing ot scream out some serious rpms n power across the board

looking at that video remember jesus had to add 500 pds to his chassis and still beat that honda, so figure thats 5 tenths

Yes it so dam true, my hatred all started when when this punk *** kid with the
usual ricer body kit and goya can muffler reving his 89hp engine at the stop light.

Long story short,i eat his *** for breakfast,and then begun my hitler like hatred of smug honda owners..
