250 hp in a 2600 lb car RX7 and 250 hp in a 1900 lb car whos gunna win....now if you have a turbo and motor work done to the r then yea i can see it happening but not NA street legal
What are you refering to as street legal? All you have to have are lights, street tires and the car will be street legal.

ozvazquez,

i really like that Starlet. with the right engine setup, as long as you can keep it straight for the whole run, i don't see why you can't bust up that Civic. go for it, bro.

k20 vs 13b both na

Thanks for the support. dmolchanoff just doesnt understand horsepower is not the only thing need to win a race. Look man I work on k20 and all the rest of the honda engine, but nothing is like the power of a rotary. The suspension setup and drivetrain will play big part in this race. One of the biggest thing is rear wheel against front wheel. More pics to come soon. Will be buying the crossmember and 4 link setup soon, but i first have to strip the car down and sand blast it get a good look at what im up against.

i know horsepower isnt the only thing you need to win a race im just saying that if the kid has money for his k20 hatch project and he knows what he is doing when it comes to tuning then that k20 will be hard to beat with a limited budget rx7 build.....and street legal meaning not a full open exhaust ( in a rx7 that is extreamly loud!!!) having a legal exhaust so you dont get pulled over every 20 minutes for DTP!!! im just saying if that k20 is built and tuned right and the person driving knows how to drive and he has tires to hook its gunna be a good *** race!!! althought i think the k20 might have it i would put my money on the rx7 cuz hondas are junk

A bridge-port or p-port 13B will eat the K20 alive... I just smoked my friend's built LS Vtec, gutted civic hatchback with my bridge-ported 13b, full interior GSL-SE rx7. All I have is an old school fully bridge-ported 4 port 13b with a tiny 48 IDA weber carb and one MSD box on the leading coil.

b18 ls

Ya the b18 is cheaper and more parts available. At the end of the day its rwd against fwd. It still a toyota starlet (not rx7) against a civic hatch. The civic weighs more , it wont have the traction the starlet has ,and most of all the launch. Ya the k20 has all this potential to build mad power , but it will cost alot. I work on honda all day, I support my family from it, so if didnt know the power i would not have taken the challenge.

how do you figure honda's are junk? i know, i wouldnt even think honda and junk can be put into the same sentance. i love my 13b and my rx7 but my little b18c1 hatch would have tore my rx7 up dollar for dollar to time on the quarter. the honda's are so much easier to track down parts for and to mod in general. i bought the rx7 for the challenge and the chance to do something a little off the beaten path as far as the local scene goes. eta per dollar i think goes to the hatch. (counting labor as a cost also, my times worth something). racing isnt all about hp like a ton of people are saying some guys just won't understand that.

alot of this is going to be driver skill also so the only true way to see the difference would be to pay the track pro to make a few passes in each car. unbiased real results. lol i know its all about a good time and should be interesting to see the results.

just saying if i had money out on it i would go for the hatch, that k20 is a monster...

a monster

Ya k20 might be a monster , but a expansive monster. Your comparing a b18 to k20.
Its like applies to oranges. The header alone is $600 to $800. You can fing a b18 header for under $200 or the guy next door has it hanging in his garge. Who has k part just laying around? Nobody!!! This guy is already felling it in his pocket.

You obviously don't know how to work on rotary engines then. Rotary will always be the cheapest engine to mod. There's no valves, pistons, cams, etc to buy. You get a seal kit and some decent apex seals and all the mods are done free with a die grinder- porting. It doesn't get any cheaper than free! You just have to know what the hell your doing.

k20 vs 13b both na

13b engines are putting out over 400 hp to the wheels so the rotary would take the win.
