High rev NA 5 cylinder

You are right on the SS pipe cost. If you dont pay for labor 6FT of T43 will be around $340.

The fact that you say you know people shows that you don't know what you're doing. How would you know what they did will work well with whatever setup? Just because it works on another car, doesn't mean it will work for this car.

Compared to other markets, these cars are lower production than say a Camry, so only a select few know what they're doing. Even if they know what they're doing, they still get it wrong. Knowing how to fix it is the other part.

But by all means do it. You're here for answers. Most people who pioneer don't ask the right questions. They just do and post results so others don't make the same mistake.

Im not trying to just talk about it.

This WILL happen this fall. Im just kind of busy right now with school., so the funds will be limited.

What i mean by i know people is i mean, there ARE people who know what they're doing with Volvos around here. Most of the guys who work at the dealership i work at are sometimes-active members on here. They build their own cars. One of my good friends has a 487 WHP S70 "(Automatic) built by a European shop in our city.

These things can be done, it's just all about who wants to take it this far. I've already talking to the dyno tuners around here and they're down for the project and some of them use to own Voplvo 850's and stuff like that. They still keep up with it.

I mean honestly if this wasnt my daily, i would be building this into a NA autocross car!

I like being weird and abnormal about it. Have you ever heard someone brag about a NA Volvo? nah. I wanna be the first that can.
Just like my buddy who's building his NA Civic Si, everyone just tells him to turbo it.
He doesnt want to because he likes being NA, it sounds different, its a fun ride, VTEC cracks hard, its alot of fun. Everyone hates on it, but its not what other people think its what you want..

This is going to happen eventually before the year is up. I promise that, its just going to take time.
I wanna be the person to bring some light to the 2.4i owners. And also tired of people saying "Sell it and buy a T5"
Which obviously IS the better option BUT its impossible for some, like me.

Uhhh... Custom made stainless steel exhaust from one of my welding friends is gonna be $300 lol.
For now im gonna run my exhaust right now. Straight pipe
Stock intake (its good for 350+)

Im not worried about the reliability of a E85 tune either. Especially on our cars. Built plenty tuff.

Its not as expensive as people "think" its ginna be. Just gotta know people like i said before.

Trust me, its not that expensive. People just over complicate it.
And im kind of suprised that people on this forum hate this idea do much? Its possible and its not that hard if you know people. Im not worried a bit about it.

Stock intake is good for 350+ on a turbo car. NA cars are much more sensitive to intake design. Chances are that you would see a gain from swapping it.

I built a high comp, high revving N/A Subaru EJ25 and can say that it's more expensive than you think to do properly. That car even had a ton of aftermarket support that this platform does not. Yes, you can make it loud and probably pick up 20hp all said and done, but for the money there is always lurking disappointment when you are asked how much you've done to it and what power it makes and you mumble out something around 200. I went from 165 crank HP to 232, and that was a balls-out, fully built race motor when finished, worth more than the car it sat in. It didn't idle well, didn't pull until over 5k, and was just not fun to drive unless you were in a competition environment. Even then it was only on par with stock turbo cars.

Nobody is trying to rain on the parade... but a few of us have tried it and can tell you... there is a reason why forced induction is commonly used on small displacement engines.

I just want to go on the record here. It looks to me like FosgateLife wants to learn how to build a performance engine. Auto producers want to manufacture a engine that is reliable and cost efficient and yes the turbo is the best out of current technologies to produce a low cost improvement on any motor platform. We all agree on that..
What I believe the purpose here is to look at what has Volvo left on the table as far as improvements go. I think that it is a fantastic learning opportunity here for FosgateLife. We should help and not discourage him. I look back on how I learned how to build engines when I was in college and if I did not have the help of the local Porsche shop and PCA community I would have been lost.
FosgateLife I will share what I know with you. I have just finished a refresh on my 2.4 and I am starting to gather materials to fabricate my intake and exhaust parts, and massage my head. This takes time and you should plan it out in stages. I will say this make sure you have a good base to start on check your compression and if you can drop your oil pan check your connecting rods, and bearing clearances.
This is a challenge not one to shy away from understand what you are doing and it risks and rewards.... Besides turbos do not sound like a NA engine.

Keep up your good work ......

FosgateLife · Sep 8, 2014

Im trying!
And you're part way right CJ, i do want to learn to build NA motors, but i do LOVE turbo cars and i honestly do know alot about them.

The problem i have here is that im stuck with a 2.4i. Not my choice to sell or anything so im making due with what i have thats all!
I wanna see how far i can actually get without spending a TON. The gains dont matter as much to me as actually learning what the capabilities are.

CJ2 · Sep 8, 2014

what is going to be a big factor is if you can learn to fabricate. I think you said you have buddy who is going to help you see if he'll teach you TIG welding, thats a major skill set you'll need and can save you a TON of money..
You not going to find much off the shelf parts here..
oh forgot to add this engine building is very geeky it's a lot of science and numbers if you are so inclined here are a couple of articles on intakes.

Thanks man i really appreciate it!! Next goal on my list was actually welding anyways! Haha

JN2k108 · Sep 9, 2014

i feel the white blocks and red block motors are better NA engines than these 5 bangers. if you can find a way to add a vtec cam and tune for it, i'd be very impressed. i've seen a lot of the honda tuners do it on their d16 engines at auto x and they're so fun to drive.

FosgateLife · Sep 9, 2014

I have also seen that, and been in a few and you're right they're fun!

Who knows if it'd work in our cars idk

JN2k108 · Sep 9, 2014

Or get someone to machine you something that can replicate vtec cams and you have a 5 banger vtec motor lol

TurbineWagon · Sep 10, 2014

We already have a form of VTEC really. It's just not setup to have a marked changeover. Our cam timing is already varied by the ECU.

...Unless the 2.4i is different but I thought it had VVT as well.

FosgateLife · Sep 10, 2014

Im sure it does. I can hear the exhaust change at around 4300-4500rpm.

CJ2 · Sep 10, 2014

Vtec has 2 different cam profiles on one cam that's what makes them special.

Bunyanderman · Nov 20, 2014

Any more thought on this?

FosgateLife · Nov 20, 2014

Havn't really thought anymore. If i dont end up doing a T5 swap im gonna weld custom manifolds and throttle body with a E85 tune and a built auto trans

If your wanting to go to the track why not start by trimming the fat off your 2.4i start gutting anything you can afford to lose for weight then tap into the suspension. In my opinion a car doesn't have to be fast or have a curtain sound to be fun to Drive. Hell even racing a go cart is fun it's all about how you drive it.

FosgateLife · Nov 20, 2014

I know i know.
But im getting to that point where the speed is getting to me. It is literally... So. Slow.
Slower than a 95 avalon with 270k miles onitand hasnt bad an oil change sincd 255k...

I cant take being this slow so im going to look intoother options.

I just started off with a ****ty platform... Which is kinda what makes it cool but sucky at the same time. NA sounds so good.
If i can get to 210whp NA i will be happy.

I got a quote on getting the tranny built. $1200 and thats pushing it they say. It'll hold up to 400whp they say. I teresting thought...

FosgateLife · Nov 20, 2014

Its my daily, other wise it would be gutted in the back.

I just need a older volvo really lol

jondevieonS40 · Nov 20, 2014

The youth in me says do what you want ( much like I did with my s40) I've put in $3000+ and only making 250Hp when I coulda bout a fox body and dropped an engine for the same price and have at least 3-400HP but I'm happy with it cause it's what I wanted.

The wise old fart in me says spend your money on something more built for the track but screw it do you.

850s are always easy to work on
