250Hp 420a

Im just curious as to what it'd take to get a 420a to about 250-300HP but prolly more around the 250 mark?? maybe even 225??? I dont want something that im gonna take to the track and race but I do want something with a little kick. Something I dont have to be ashamed of at a red light but at least keeps up. Theres a new honda accord in town that has some mods to body but not sure how much on motor, but im guessing its the usuall mods...stuff that everybody does. He is sponsered by a local graphic business in town and I would just love to give him a run for his money. I've never raced him b4 but im sure he'd kick my a$$.

dont overestimate hondas man, i raced a 2000-2001ish vtek civic a few weeks ago in my 3g rs with no mods and still beat the thing

If it is one of the V6 Accords, they are no punk. 2006 Accord V6 Coupe 244 horse.

theres a D16....yes D16 that is about to push 400+whp in my area.

to get ur 420a to about 225hp you'd need a turbo kit, new injectors, fuel pump, fpr, boost gauge, a/f gauge (preferably a wideband) and tuning. with this setup you could run probalby apx 250-275whp. with wideband, tuning, some kind of management, and rebuild bottom end you could run close to 300-325 (i'm planning on runnin close to 350-375 on mine)

.... 250whp from 10psi, no.

When you are ready to step up, Hahn RaceCraft Turbosystems can be easily upgraded for higher power levels. The Stage I to Stage II upgrade contains all you need to add an intercooler system and increase boost pressure for a power gain of 50 HP!

so the 420a makes 140hp at the crank stock, so thats 190hp to the crank if you get the whole 50hp power increase... thats like 160-170 to the wheels maybe. For 250 to the wheels your going to need something like 15psi-ish and some extra go mods.... basically if you dont have round 7g's to spend, then no. If you do your looking at a built short block, worked head minus cams, bolt on's(udp,throttle body, plugs, ect.), mbc, portfuler system or safc 2 with a msd/crane ingition box, after market bov, full exaust, and a better clutch.

Its about a 2001 ish model.. and im almost postive its a v6. Thanks for the reply RCJ i like hearing some helpful information for a change. Im still waiting for slow420a say something.

That was creepy out posts were 19 seconds apart

.... 250whp from 10psi, no.

where did i say anythin about only pushing 10psi??

basically if you dont have round 7g's to spend, then no.

this is if you buy all brand new parts from major companies... if you piece everything together you can get ur car up there with somwhere around 3500

well because you didnt mention any internal work at all which means 10psi max on that engine, which means no 250hp

my bad, not sure why i didn't add that but i meant to put it in there....

x2 and you didnt say anything about a bigger wastegate or mbc. Also at that high it would be wise to use some sort of after market ingition control module.

I consider hahn a major company... the hahn stage two kit with a smic is 3,000 dollars alone (howell automotive). So if you can get injectors, a wide band, fpr(which the hahn kit comes with), fuel pump(which the hahn kit comes with), boost gauge, some kind of managment, a shot block build(which you inferered to be included in the price in the post below theengineer), and some dyno tuning for 500 dollars let me know.

Soo lets say you go with the stage two kit for 3g's. Howell sells a bottom end rebuild kit for 1000 dollars... but lets say that you build the motor your self so you dont have any labor included in the price. Lets give everything else a low ball/ebay/used/fell off the back of a truck price... wideband 200, injectors 50, fpr 100, boost gauge 20, managment... safc? 200, and no dyno tune. That alone is 570, i can promess you wont find anything that cheap unless its some once in a life time deal. So thats bout 4500 assuming you get just the bear minimum. If you were to do it right you would want a hahn port fuler(1500), clutch/flywheel(600?), mbc(50), bov (150), wideband (200), egt gauge(150), msd/crane box (500) plus the bottom end kit would leave you at 3100 dollars. Thats if you dont get the block serviced(you would be stupid not to if you were dumping all of this money in your car), building the motor (not for beginners), and installing it in the car(again not for beginners), and installing the clutch your self. That also dosent include shipping or tax.

i lost my eclipse...got a civic ex..look out..haha...to many technical problems with the eclipse..

Right and like i said if you D O N T go with brand new parts from a majory company, you can get it done for that cheap, piecing together a turbo kit from misc providers and 2nd hand people, you can get it done for close to 1000-1500, after that ur lookin at wideband, ignition, fuel, and clutch. get it tuned and like i said you're lookin at around 3500, it's not exacty by any means but it's a round about price. so far i've spent 1100 to get my bottom end forged and ready for boost, this is going through companies with brand new parts, i have found a pretty good tubo kit for 1800, so i need a wideband that i'm getting for 180, MSD i have found somebody trying to get rid of an entire package for about 350, friend of mine w/ 425 injectors, and after i get my Greddy E-Manage and tuned i'll have spent about 4300, yes it's higher than the 3500 i mentioned but i also bought EVERYTHING needed for an entire bottom end rebuild including the ARP head and main studs, heavy duty head gasket, new rod and main bearings, urethane motor mounts that i didn't have to get, also bought a new timing belt, water pump and oil pump. those you don't have to change but i'm just wanting to do everything right. i'm not arguing that if you do it up big, with the best people with the best products that it won't cost you close to 7k, i'm just saying that it is possible to get a turbo on ur car and run it close to 250hp for the budget of close to 3500.

so much cheaper to just get a GST or GSX and make 300hp easily.....im not tryin to get sh*t started but its the truth!!!

Sorry I miss understood you, I thought you ment that you were buying all of the parts from major companys.

Anyway, the only smart person in this thread is dixonsgst, I would never buy a 420a ever again.

yep, no controversy over that one. but i've ready from several places that if built, and by built i mean done right!! the 420a can handle more than the 4G63, let me remind you that this is what i've HEARD!!!!

Hey, I have the 420A and it can handle alot. But you will more then likely never see a six second 420A. I would be willing to put money on it.

i would put my life on that. there will never even be a 7 second 420a lol

i KNOW you are talkin about the 1/8th right? i have a friend runnin 8.3s in his 420a here in SC and is about to add methanol injection which hopefully will put him into the 7s

1/8 mile i was talken about the quarter mile

I dont even think there is a 420a in the 9 sec catagory yet nvm the 7 sec

Darrell Cox made a 9 second neon... with a 420a, it ran a 9.24@153. There will never be a time lower then that in an eclipse, they are just too heavy. Also never in a neon either seeing how the 420a and its sister motor the a855 are no longer in production.
