Questions Regarding Turbo Kits

[blink21me]

I'm not a turbo guy but I know for a fact you gotta make sure you're engine is healthy enough to handle boost... Do a compression check before going turbo, make sure #'s are close to their stock's and that they're not significantly far away from each other...

1. Meron po bang turbo kit para sa Mitsubishi Lancer 1996 na all-stock?

I'm not a turbo guy but IMHO masmadali mag-piece at mas worth it kung magk-customize ka...

2. Kung magpapa-install ako ng turbo kit, anu-ano po ba exactly ang kailangan ko pang palitan na piyesa (air filter, racing cams, etc. if needed)?

nothin else... but keep an eye on your maintenance sheet...

5. Ilang percent/gaano ka-significant yung added performance?

depends on the car...

6. Maintenance: mas mahirap/madami po ba?

On most situations yeah... You gotta keep an eye on everything, even head studs... double time sa maintenance... But if tuned right and naka-set in mind ang limitations, everything should be good, but not as good as if it was stock...

7. Most importantly, yung fuel consumption.

TIA. :cupid2:

I heard that people increase gas mileage when out of boost, but of course those are tuned right... FUEL tuning tuning tuning is probably the main Key???

RE: fuel consumption... as long as you stay off boost, it's relatively the same... as long as it's well tuned. Depends also, how early your turbo spools up.

But on boost? I had a boardmate who stuck a turbo on his 1.6. His gas consumption was just so-so with light throttle... but he could go into the teens in MPG on boost. Another boardmate with a turbo on his 2.0 gets 6 km/l in traffic... a pretty big fall from the 8-9 km/l us Naturally Aspirated boys get...

Shucks, 2 days weekend hiatus lang ako ay dami na sumagot (relatively). Nung pinost ko kasi ito nung friday ay nilangaw eh. Akala ko wala ng sasagot. Hehehe.

Una sa lahatay maraming-maraming salamat replies ninyo. Wala talaga akong alam sa internal mods ng sasakyan (hanggang PC lang ako... hehehe) so talagang medyo bulag ako sa topic na ito at yung mga sinagot ninyo ay talagang malaking tulong sa akin.

*wildthing can you please explain more about [turbo] "pressure"? (kung ano ang meron kung high or low pressure)
*Mamar medyo madugo pala kung aabot ng Php150K. May nakita kasi ako sa isang ad dito supplying bnew and surplus turbo kits Php60K++. Ang iniisip ko eh salpak-tune-takbo na agad ito. Hehehe.
*ssaloon chief, diba kayo po yung may blue na 1995 Galant Super Saloon na turbo-equipped na? If you don't mind me asking, how much inabot yung set-up ninyo? Btw, pizza-type na po yung sa akin.
*ronald_m 110KM++ na po ang mileage ng sasakyan. Budget? Mapaguusapan naman po yan basta reasonable at kung kailangan po talaga palitan ay OK lang. About sa capability ng engine, ano po ba ang dapat ko icheck at makita para masabi ko na "capable" na ang engine ko?
*blink21me medyo similar po kay ronald_m yung sinabi ninyo. When you say "healthy", ok na ba yung wala namang kalampag, alaga sa tune-ups and other periodic maintenance? Or meron pang napapaloob sa salitang "healthy" sa car domain na hindi ko alam? Hehehe. And about your statement sa maintenance: But if tuned right and naka-set in mind ang limitations, everything should be good, but not as good as if it was stock... - should I expect na medyo mas malala ang maintenance ng may turbo kesa sa stock; na mas prone ito sa problems?
*niky how do you exactly stay off-boost?

Follow-up question as I've noticed sa iba replies:
1. Mas OK ba talaga na bumuo ako from scratch or bumili na lang ako ng OEM turbo engine (e.g. yung sa Evolution)? - in terms of quality, reliability and price.
2. Gaano ba kabusisi/ka-tedious ang overall installation ng turbo kits. May autoshop kasi kami and I will be going to Japan next month. What I am thinking is bilihin ko na yung ibang parts doon tapos ipapakabit ko na lang dito. Ang mahirap na part na lang siguro ay yung tuning na sinasabi (or pwede na rin bang kami ang gumawa nito?).

Again, maraming salamat po senyong lahat na mga gurus. Hehehe.

[ILuvDetailing]

how do you exactly stay off-boost?

AFAIK if you keep your revs low lets say below 2.5K RPM - 3K RPM the turbo won't kick in.

1. Mas OK ba talaga na bumuo ako from scratch or bumili na lang ako ng OEM turbo engine (e.g. yung sa Evolution)? - in terms of quality, reliability and price.

I'd say an OEM turbo engine would be a better option, don't know about the price but it will be more reliable.

* kikkomann

yup ako yun. mga 110k++ inabot for the front cut, install and misc parts. pizza na pala yung sayo, mahal pa kasi choices ng engine pang pizza. 2G MIVEC nasa mga 60-70k ata, evo 4-6 mga 140-150k pa. wala pang install mga prices na yun.

[niky]

Tama si ILD... just don't let the turbo spool up. It depends on the tuning of your turbo... on some kits, you don't get positive pressure right away, so driveability at low rpms is about the same... maybe a bit sluggish.

You could put a boost gauge in... just watch the little needle and learn what throttle inputs and engine speeds don't send the needle flying... ...in other words, to keep gas consumption the same, you should have a very, very light foot on the gas pedal.

60k + installation + tuning will still get you close to 100k. My clubmate got his kit secondhand for much lower than 60k..., but I think he's spending close to 90k na rin... and he still might need a new manifold... his current turbo manifold cracked from the heat (he was using header wrap on it... too bad).

Spending that full 150k assures you that you won't have any problems with the installation, as long as you aren't looking for mad horsepower numbers. If you're using a 1.6 liter engine, maybe 170hp is a good safe number for a "cheap" install. (Ironic, then, that this stuff ain't cheap!)

AT 110,000 kms... hmmm... set aside money for an overhaul? As long as it's not eating oil, it should still be okay.

*blink21mem edyo similar po kay ronald_m yung sinabi ninyo. When you say "healthy", ok na ba yung wala namang kalampag, alaga sa tune-ups and other periodic maintenance?

"Healthy", hindi mo yon basta-basta made-determine sa tunog lang... Kahit pa up to date yung maintenance mo, that's not an assurance na maganda yung condition ng engine mo... Correct me if I'm wrong, but the best way to know is to perform a compression and leakdown test... (search mo na lang kung ano yung purpose ng dalawa kung hndi mo pa alam...) When I said "if tuned right and kapag naka-set yung limitations", ibig ko sabihin na dapat yung magtu-tune ng kotse me eh alam yung ginagawa niya and may experience... Also, usually may manual boost controller ang mga turbo'ed which allows you to raise and lower the "boost" to a certain PSI... dapat alam mo kung ano yung limitations setup mo to safely run it, like, kung and engine mo eh hndi ni-re-built and hndi prepped para i-"FI", mababa lang dapat yung psi mo (I don't know what's safe for your stock car but it's usually 6-8 psi on Honda's)... Kapag napataas mo, masyadong risky para sa engine mo and pwede mangalas yan... . . . And yeah, mas-high maintenance and turbo... lalo na kapag hndi naka-tune ng maayos... Keep in mind na tuning plays a big part in maintenance, too...

Mas-ok definitely kung bubuo ka ng sarili mong kit IFF you know what you're doing and if you know where you're going ~sounds like you're not that type of enthusiast...

Kapag magbubuo ka ng sarili mong turbo kit, kelangan alam mo rin kung ano yung magandang quality na gawa ang mga materials... kapag relatively "so cheap" yung isang kit comopared to the other, look for differences, may mga kit diyan and turno manifold nagk-crack at naghihiwalay within a week or so...

Also, kapag bibili ka ng engine, kasama sa concern mo yung drive train, tranny, linkages, and such... You can't just buy an engine and expect na complete bolt-on yun sa kotse mo... Also, fitted ba yung engine ng Evo and other things sa kotse mo? Evo's an AWD...

2. Gaano ba kabusisi/ka-tedious ang overall installation ng turbo kits. May autoshop kasi kami and I will be going to Japan next month.

Bolt-on turbo kits are easy to do, kung kaya mo magpalit ng header kaya mo ilagay yung bolt-on kit by yourself, except that it takes much more time... Sa tuning, you gotta have the knowledge, other than the software and such tools...

[ssaloon]

bolt-on ang evo 4-6 sa pizza body ng lancer. you can just lock the tranny to FWD. mad wheelspin though :lol:

[niky]

I still remember the last time I saw one of those bad boys drag race... kawawa siya talaga sa Civic Sir na kalaban niya...

In one corner, 180-200 hp Civic... in the other 275+++ hp Lancer... both FWD... both on 15-inch mags with street tires... I think the Civic hit the 1/8th mile mark before the Lancer even found traction...

ha! shows that FWD's need that much power... It's either the guy in the lancer didn't know how to launch, or he put allhis money to the engine and didn't throw a penny to any of the suspension components... There's a local here driving a built NA Integra GS-R pushing no more than 200 to the wheels... He hits high 11's to mid 12's...
