My MKIII - My Project - Need a few answers

mnewxv · 08-29-2008, 12:28 AM

heres the deal. You get the header, a pipe takes that to the cat, and rest is just called the catback. This would have a big hp boost of you did it all, im guessing 10 for header, cat prob adds 3-5, and catback another 5-10. so about 20-25hp is my guess. maybe 30. Intake, a clean, non restrictive intake is a good thing. you have a K&N filter right? I like K&N, but is it just a filter in the stock box. An aftermarket intake will get rid of the box and expose the filter, letting it breath much better. expect 8-10hp over stock. boost controller does exactly that, controls your boost. you can up the boost, which gives more hp, but also more strain on the turbo, so good idea to get intercooler/turbo timer to keep that in good shape. good luck!

Ty for the responses so far!

So, basically, I've been listening to my motor and I think my valves may need to be adjusted .. it sounds like a couple are tapping... I think these are manually adjusted, will have to look into that. So, at the same time, I can redo the headbolts. Now, if I use the ARP ones, can I get away with just pulling and retorquing each bolt individually? Or is it gonna need a bit more prep than that?

At the same time, (because I got the top kinda cleaned off anyway) I may as well be prepped to replace some of the hoses I showed with oil on them as I think they are leaking somehow. And, because Im there... I may as well do the upgraded intake at the same time. Bad part is, Im gonna have to find the cold air intake without the filter, as I already have that part.

Thinking K&N for the intake.

Quote:

Designed to increase horsepower and acceleration. Engineered to specific vehicle. Replaces restrictive factory air filter housing with K&N high flow element and necessary components. Works with O.E. computer and emission control systems. C.A.R.B. Exempt. Maximizes performance while adding value with the washable and reusable K&N high flow FILTERCHARGER element. All K&N filters are designed to meet a filtration efficiency of 97-98% while achieving maximum airflow..

Depending on how long it takes me to amass the parts I need, I may have to wait on the exhaust (if I can hold off until November.. then I can do all at once, but I dont think I can wait that long as the leaking oil annoys me, because until I fix the hoses, I wont know if anything else is leaking...

I am planning to steamclean the engine compartment after the hoses so that I can find the leakages better as well as clean the undercarriage as much as I can as well. That will give me a much better picture of what is currently leaking and what is from past.. as now I am looking at both..

No header needed, but make sure the mod'ed exhaust has a resonator and good muffler? I think my son-in-law has something lined up for me already on that point... : ). Header is not needed unless I install a bigger turbo (which I wont be doing).

I think I'm starting to get a good map going of what to do, and it looks all fairly affordable.

With the Turbo timer, I think I have to also get a new harness. I haven't found anything really on boost control yet, and the intercooler looks pretty straight forward.

you shouldnt need a new harness with a turbo timer.

edit: maybe you do, but its avail here. not sure if its cheap or not compared to other stores.

GReddy Full Auto Turbo Timer

Regarding the Turbo timer in a stock MKIII... does anyone here know if I need to order the harness? Its only 10.00 so no biggie if I get it and dont need it.

Also, does everyone put it on top of the steering column? Im thinking of embedding it in the dash somehow. Maybe make a faceplate and put it in the ashtray slot.. hmm...

Has anyone used this or think its worthy of consideration? (my car is going to remain mainly stock and not raced too much)
DNA Manual Boost Controller - No Boost Spike

Also, I may have mentioned this before, but our max Octane level at the pumps is generally 91... Just for normal driving, it seems to be okay, but would octane boost help the car (from a longevity standpoint, not just speed)

Found out what the toggle to the left of the steering wheel is for. It used to be to lock the TEMS into 3rd position. When the engine was repaired (it is original block and heads I found out), they disconnected the wires. Luckily the previous owner misses the car and doesn't mind telling me its history.

well if you mean like the little autostore or gas station octane boosters, dont bother, their only raising octane in small amounts from 91 to like 91.8 or so lol. boost contrlloers come in manual or electronic, AEM makes a good BC that is also a boost guage, try Boost Controllers thats a whole page of diff BC's so you get an idea, i really like AEM's tru boost, or you get spend the money for one of the best, the blitz sbc i color, but at close to 600, thats for someone looking for the most power they can get, and will need to be tuned by someone knowledgable, the aem is, ooo what does this button do? *push* raises or lowers boost and thats it lol.

At this point, I think the aem sounds best

mnewxv · 08-29-2008, 05:54 PM

well its good to get a fresh tune for just about any upgrade you do, whether it be a full exhaust, ANY turbo boost controller if your raising the boost even 1-2 pounds, new turbo, new heads, etc etc. Turbo timer doesnt of course since it isnt so much an upgrade to performance but one to longevity.

as for the octane booster, 91 should be fine unless your like pushing 400WHP or more. how much is a gallon of 91 octane up there? most stations here have 93, with some every now and then having 94. but with the prices mine doesnt seem to mind 87 (manufacturers spec)
