130hp / d16a6 ?

[red dragon]

is it possible to get 130 horses out of a d16a6 all motor? and how much $ would you be lookin at to get it there? and could it be a daily driver? anybody know if they make limited slips for a 90 si. thanks for any help.

get a D16Y8 head, a PR3, and a DOHC ZC tranny

[red dragon]

what is a y8 head off of, and what is pr3, i take it the zc tranny is limited slip and it will bolt to the d16a6? is the ratio any different from the si? thanks

Dont waste your time with that all motor route, spend $300-350 on a simple safe zex dry kit, run a nice 65 shot on it (safe no matter what any tool says). Youll be doing circles around the moron who goes out and does a minime.

i was going to go with a zex way in the future but wanted to do the motor first. the only thing i have to work with right now is a block with internals and tranny. the head is gone and map sensor is gone. i can probly get a stock head free and having a machine shop work some magic on it but am maybe considering just getting a head package. dont really know on the pistons what to do if anything

ITA crx's get about 125hp to the wheels with really only boring out the block .40 so yes it is very possible.

quaife also makes a good LSD for the si tranny, costs about 900 brand new

as for trying to get 130 cheap... better cam, I/H/E and maybe a small shot of N2O and your good to go

[red dragon]

do you think that a limited slip is worth it on the street or is that mainly a race application thing. i have seen ita on road racing cars. is there a site for these guys where i might get some information. any idea how much a ita motor costs just out of curiousity?

[silverkorn]

www.scca.org for race information

to have the engine built will cost around 3k with you providing the core.

the LSD helps when you have more power where you need more acceleration since one wheel would be spinning. if your going the be street only i wouldnt go with a LSD unless your making over 200hp, otherwise yea its more a race thing then anything

[red dragon]

thanks for the info. i will check out that site. 3 grand doesnt sound that bad for a all race motor. could you swap a zc motor with nitrous for the same price or would you have to rebuild the zc for nitrous? i can do the labor myself

[silverkorn]

if your serious about the engine being built let me know and i'll give you more info about it

but keep in mind that having a race motor and a street motor are two different things, as the street motor should last to and beyond 100k miles while the race motor will maybe last 1k miles, since each race is about 25 miles long. so dont expect a race motor to last on the street.

i never gave that a thought. racers must freshen up their motors every thousand. i know drag racers sometimes rebuild every race sometimes but never thought about road racers doing it that often. i guess there is no happy medium then. its either race or street. decisions, decisions. the bad part is i really dont have 3 grand that i can just grab out of the bank but i have been toying with the idea of selling my prelude for the project. i just sank a bunch of money in the motor for that. (before i ran across the crx) even though i really love my lude it may come to that. any thoughts on a motor would greatly be appreciated. race or street. either way i want the car to run and run well. i will also continue doing searches here. i know there is a boatload of bolt on stuff for the crx but the internals is where i am pretty much lost.

[silverkorn]

well usually the road racers will rebuild the engines after the season is over, but they arent putting that many miles on the thing in a single race season.

for you i would suggest getting a b16. if your looking to spend close to 3k then this would be the way to go since by the time your done with adding parts and getting mounts you will be close to that figure and you should have more then 140hp to the wheels

[crxkid_420]

doesn't an a6 have 117 stock?
cam gear and underive pulleys
maybe an exhuast

that would put you at 130, not to the wheels but a 127 horse z6
puts 107 to the ground, not losing that much power through a f/f

you could pull 130 to the wheels easy

I don't know what your budget is on this A6, but make sure you look at this carefully. To make that much power on a SOHC will cost some bux (maybe not if your doin the rebuild yourself) Another aproach is to compare prices with a swap, instead. Personally, I love them A6's. But when mine tanked I did all sorts of research to see how a to build it fast. In the end I ended up swapping it out coz it was the cheaper and less downtime. Oh, and make sure your engine can take the spray b4 you go that route.

Best person to ask about this is SilverKorn, heheh he sees it first hand.

[silverkorn]

the a6 has 108 (90-91) stock at the crank... figuring 15% drivetrain loss and you have about 92 horsepower at the wheels

and i was talking about 125 to the wheels, with a 15% drivetrain loss works out to about 147 hp at the crank

so now your looking at an increase of 39hp with the only major power adder is .40 overbore and a I/H/E
