I am wondering approx. max power I can get out of a S5 N/A say with some engine porting, straight exhaust, less restrictive intake, maybe larger fuel injectors. ***Any other upgrades????***** Maybe Nitro

All of you may be wondering why not just upgrade to a Turbo engine or do a turbo upgrade/supercharger. and that is because I will be dropping this engine if I can get it above 200 hp (target would be around 240) into an older Toyota or Datsun and space may be limited.

Straight exhaust, intake upgrade, engine porting, other recommended stuff.... do you then have to upgrade the fuel system? Could the stock computer handle the extra power? or what should I consider? if I would have to upgrade the computer system --- is there someone out there that can map the existing ECU for the new upgrades (if required)?

I know this is a pretty loaded question but I know a few out there have done it already. Please let me know.


Thanks

With a big enough port (P-Port) you can get past 200hp, sure. Have fun tuning/driving it though.

Maybe if you picked up a s5 engine, did a large streetport, got a standalone ecu, bigger injectors, depending on the money aluminum engine parts.

Deleted ps/ac, exedy clutch kit, mazdatrix lightweight aluminum flywheel, ford taurus electric fan, full koyo aluminum rad, K&n air filter, remove emissions, tb mod.

You will have some good power with possible driveability. But are you gonna daily drive this car?

in the end power to weight is the only way your gonna win.

again you still are giving people wrong info...stop posting **** you dont know please som mod read this guys last couple of post

they are not helpfull at all , lifting your post count doesnt create **** but a phony who doesnt know ****

well if i was you i would do this set up since u want to stay n/a

fresh rebuild w/ bridgeport
racing beat intake manifold
holley 650...w/ high floe fuel pump and fuel pressure regulator
light weight flywheel and a good streetable clutch
full exhaust with headers
if you where to go standalone and add some injector bungs with some 1600cc then you will be more than 200hp tuned

remember this car will not be a daily driver anymore and you will have to tune it to get its max potential....s5 n/a were very low horsepower doing p port will not work so dont read that idiots post

it all depends on how far you want to go...this set up is as close to street driveable because i seen the same set up myself

That's not completely wrong... A p-port will get you above 200 hp, like he said.. probably closer to the 300 mark. The idle will be less than ideal, probably 1500+ RPM IIRC, fuel mileage will suck, and it will be LOUD as hell. You will probably need an aftermarket EMS to run the car, as well. Along with more fuel delivery. Some of the builders will guide you a bit more than what I've said, but I'm just trying to give you an idea of what it will be like.

Try doing a search on peripheral ports. After sifting through a bunch of bullshit, you should find more information.

yeah true in a part but you have to read what the thread starter wants...he doesnt even know what a p port is..and if you do a p port what are you gonna do about your intake manifold or better yet how to make it work with all the STOCK component he has....remember just telling someone do a p port and you will be at 200hp isnt enought

you still need
p port housing
new irons because the stocks are use less now they will have to be pluged
the stock rebuild kit isnt gonna work unless you want flat apexes in one turn
how about your intake manifold it will be custom too

after all this this will be a race car...remember he is stock he wanst to reach that point but able to drive it

+Eleventy. Werd up.

Thanks for the info. I am planning on rebuilding the engine, doing a large streetport, upgrading the injectors to the TT, straight pipe and a large intake.

My concern then would be the fuel system and the ecu. With these mods, should I upgrade say the fuel pump?

As far as weight is concern (on engine), I will removing PS, AC, air pump, solenoid rack, etc.

Forgot to ask about he ford taurus electric fan? Help me out here... is this the fan for the radiator.

Suggestions on stand alone computer system (bare bones).

spot_skater

I'm 90% sure the stock ecu can handle a street port, and you MAY not need to upgrade the injectors or the fuel pump. A good idea if you're not going to go stand alone with your setup would be to get some kind of a fuel controller. An SAFC seems to be the #1 choice around here. It's made by A'pexi.

superfastrx7

Thanks P-port is out.

yes the ford taurus fan is the one we all use if you are on a budget...you can find em for about 30 bucks at the local u pull it
and take the relays too...you will need to wire it up to the fan

standalone- well it depends on what are your goals,money,what the car is gonna be used for, just a basic e6k will do

superfastrx7

I may actualy enter next years $2,007.00 challenge. so I have a limited budget. As you can all tell, I am looking for the most HP to weight ratio. and not a daily driver but rather somthing that will last a few weekends.

Alex Rodriguez

iTrader: (137)

to a certain point because the stock ecu cant handle all that info so dont please dont do a streetport on your stock engine without any supporting mods done,
steetport will require you to get
bigger injectors
bigger pump
intake and exhaust to breath better

and the stock ecu will not know about them injectors...

safc is the best choice you can do, but your stock ecu isnt gonna let it push some bigger injectors so now the safc is useless

Alex Rodriguez

iTrader: (137)

well then what you want is a race car lol

look bro just remove as much dead weight as you can from it
get a stand alone with some bigger injectors
do all your supporting mods...fuel,intake,ignition,plumbing
and do a bridgeport

thats the max you can do to your lil n/a if you are staying n/a

The ford fan I think is a good idea, yes it's the fan on the radiator. You should also get pineapple racing 5th +6th port inserts. For the ecu go for a megasquirt by zeal.

I've heard about someone using a 88 crx honda and throwing a 82 corolla tranny on a 13b and taking off but I'm not sure if that is possible or not.

superfastrx7

Thanks for the help. I am doing this just for fun and I belive this s5 with a light weight car.... since I will install this engine in a Toyota/Datsun/Fiat ought to kick some ***. I have picked up a 91 rx7 for $200.00 running but will take it apart and rebuild it. So I figured while in there do a streetport and get rid of all the other stuff that I wouldn't need.

I am not too familiar with the ECU/Fuel system in the FC since I have only owned two FD in the past and those ******* don't have any room for error. Yeah I blew an engine in the past.

superfastrx7

That would be cool.... that is drop in the s5 into a Corolla tranny. I have heard of that too but not sure the tranny would hold (if even an option).

You just gotta make sure you use fuel injection line and not carbed line, and you will need a fuel injection gas tank or a fuel cell to make it work. With a standalone everything will be cool. I don't even know if you need a upgraded fuel pump from the fc stock pump

I highly doubt he would have to add extra bungs and 1600cc injectors even with a Bridgeport. This is an NA engine not turbo, not even people running P-port NAs run extra 1600cc injectors let alone 1600c in either pri\sec config. Bryce McEwan's 4 Rotor P-Port NA FD only runs 550cc primary and secondary injectors and he puts out 590HP.

Bridge porting and 550\720 Injectors should be fine for the power goals the Original poster wants, maybe even a race streetport. Some manifold porting would probably also help nicely.

Would you mind sending me some more information on this fan upgrade, is there a post I can referance? Thank you in advance.

My guy, this post was from 2006. There's little chance you're going to get a response.

saw that, worth a shot however!
