accord v. jetta
 

One of my friends just got a 2002 Volkswagen Jetta 4 cyl turbo...I drive a 2000 Accord V6 but its only in stock form right now...what should I start with If I want to begin to mod my engine?

intake......a short ram intake

I just got an AEM shortram intake myself it and it sounds a hell of a lot better with a slight noticable power increase. If you did the whole I/H/E you'd probably pull out 20-25hp. Anyway, with the intake you'll have a much deeper sound coming from up front and I'd guess 5hp. My 01 accord had a resonator under the front bumper i went ahead and pulled out too; it's just a waste of space in my opinion. Headers and exhaust get a little pricey though and I haven't done a terrible amount of research into them yet. How much are you thinking of spending to start yourself off?

RE: accord v. jetta
 

I wouldnt go short ram, u eithier go big or go home... Go with a full true cold air intake, then do your exhaust next, and a short shifter that can help( not engine wise but it'll still help) cahnge your plugs, thats a start

RE: accord v. jetta
 

If your gonna do cold air I would recommend a bypass valve to make sure you don't suck up any water. They are only 50 bucks and they can save you a whole lot if you ended up running through a deep puddle.

RE: accord v. jetta
 

The good idea that everyone else is giving you is to start with an intake. Personally I prefer the short ram over cold air just because of the location where I love (you never know if it's gonna rain). Changing to high performance sparkplugs and sparkplug wires, using higher octane fuel (preferrably shell or 76), using full synthetic oil will also help. Catback would be a good thing to do too, but I would suggest changing your pulleys to allow a slight increase in torque as well as hp. If you're planning on doing the exhaust, do some research and see what would allow more power and for the sake of it, don't get something that crakles and stay away from generic wanna bees (example: like greddy look alikes).

damn emex knows what he is talking about. the metal used to make a cold air intake gets real hot when sitting under the hood. the air inside gets real hot too. you can insulate it, which would be really good, but a cold air just doesnt utilize sound like it should. sound is a good friend to your motor, use it the right way, and youll be looking at some big power. (go with a short)

spend a lot of time around my friends who've done mods like that, besides i'm working right now on my second car, and currently taking classes to become a mechanic. most of my friends come to me for advice on parts.

RE: accord v. jetta
 

I run a cold air intake and i also have the whole pipe wrapped with thermal wrap. I also have a DC sports 4-2-1 which i have wrapped with thermal wrap. Helps reduce heat and the only reason why im not running a short ram is cause where the pipe ends up.... it gets more water then running it as a CAI. Plus with the plastic cover across the whole bottom of the front of the car water in general is reduced to nill in that area....... stock honda intakes are so freaking horid....... but yes..... just buy a roll of thermal wrap and the majority of the heat exists at your filter instead of the whole short ram. Right now im still deciding how run the engine oil cooler that i want to get.

RE: accord v. jetta
 

Hey what accord do you have and how are the dc headers working out for you. cause i was thinking of getting them for my car, but i'm a big sceptic, and want to know what else is out there and if there's a notacible difference between them.

RE: accord v. jetta
 

I have a 98 f23 auto..... I noticed a difference but it was only a 1/4 inch increase in the exaust in the end, I dont know specifics because i didnt dyno it.... and i couldnt justify a dyno on just i/h/e..... the most you can pray for on a 4cyl is 10 to 15 hp from that but 2 1/2 dc sports header, highflow cat, cant remember the brand, and thermal cat back....... i plan to upgrade the cat to http://www.modacar.com/products/Honda/Accord/MODAHFC..... if i can find a 65mm+ throttle body that has cruise control and im thinking of this intake manifold http://www.inlinefour.com/aceurinman.html i know too much info for most to care about.... but its a throw up on tips and opinions ^_^

RE: accord v. jetta
 

vtech controler, header, exhaust, cold air, and if you can take some wieght off of it then go find an m3 bmw and give them hell. forget the jetta you probably would have to wait up for it. unless its been tuned?

RE: accord v. jetta
 

a vtec controller seems a bit much for near stock applications, but its not like you cant get a regrind on your cam for the same price, and depending on the regrind the valve springs and retainer wont have to be changed

RE: accord v. jetta
 

Yeah, but i wouldn't suggest regrinding your cam, i'd get a new one instead (regrinded). and i think if you change the valve spring and the retainer it would be useless, since you're trying to create a slightly bigger valve overlap.

RE: accord v. jetta
 

for the purpose of having the stock cam and second cam? is that what you mean? or are you talking about a new billet cam?

RE: accord v. jetta
 

for the new billet cam

RE: accord v. jetta
 

too bad it has to be a custom from scratch cam

RE: accord v. jetta
 

i think most performance companies offer reginds for accords. if you change the spring and the retainer... and maybe even a DPR lightweight valve, you would be looking and some serious changes in your engines behavior. your cars tach out at a certain area because of valve lift, and valvetrain inertia. people with vtech have motors that are designed to operate optimally above 5000 rpm. the limit on your motors is really the mass of the valvetrain components, if you can shed a few grams in your retainers and valves and springs, your motor iwll happily rev quite a bit higher and produce even more power.

RE: accord v. jetta
 

*nods* which is what ive been looking for but everything points to custom valves and springs and i just cant seem to find the answers i need even tho i found a spring set thats good up to 9000 rpms (not that the stock rings would be happy with that at this point) but my goal is more to having my max rev at 7200 which is feasible but i need to find out if the acura f23a1 engine is the same as mine..... i would assume so but i dont like the idea of assuming

RE: accord v. jetta
 

I have an '03 Accord, V-6. I've put an AEM cold air, Magnaflow cat-back and I'm awaiting a new throttle body
With those mods( minus the thottle body ) I feel a real kick in the pants when accelerating. I like the Magnaflow becuase of it's nice sound and it doesn't sound riced out. More like a late 60s' muscle car.

RE: accord v. jetta
 

See the problem for me is probebly not getting the parts, i can probably find a store to get all the stuff (springs, light weigh valves, retainers, regrinded camshaft). the problem for me is -actually more of a dilemma, if I should completely rebuild my engine and keep building on it, or get myself a new (more like slightly used) h22 engine and go from there.
But yeah, forget my previos comment about not changing the retainers and springs.
The only thing about buying a new camshaft would be to make sure that it will increase at low and medium rpms, so the car has more torque at lower rpm's not at high rpms, cause that will seriously increase the valve overlap, turning gas milage into nothing, and the car won't pass emissions test.
So to make it more simplified, make sure you know the degrees of lobes on the regrinded camshaft.
