I4 turbo question

[CincyZetec]

i got an 02 2.0 and i'm looking at building a turbo set-up. i'm not looking to turn my car into a power monster, i'm just looking for a good power boost. this car is my daily driver too. my question is what size/kind of turbo is the best for me? i found a t25 for sale on e-bay that isn't too much. it that a good turbo? any help would be appreciated. thanks

i think a t3 would be best. i think that what some of the turbo zetecs around here are running.

[Afterhours]

A T-3 48/60 or a T-3 Super 60 is pretty ideal for the volumetric efficency of the 2.0L Zetec engine. It should be fully spooled by 2500 RPM........and will pull hard all the way through to redline.

Check out the compressor map, the goal is to keep the charge air temperature as low as possible while generating your target CFM flow.

Where can i get one of these turbo's??

Are they easy to fit? And would i have to upgrade any engine components?

You realize you can't just buy a turbo and stick it onto a car and make it work???

On turbo selection...

what about some mitsu turbos like a Super 16g... or other TD05h turbine turbos...

Actually that's almost exactly what I did. Looked on ebay for the cheapest turbo I could find, bought it, hooked it up and ran.

Do a search of my past posts in the Zetec and Forced Induction sections and you'll find a lot of good stuff.

Almost any OEM turbo will work on a custom setup but you need to do some research on them. Something for a Eclipse would be a good choice since there are so many aftermarket versions.

It takes serious work to do-it-yourself. I did two months of just research on the web looking at what other people were doing before I even asked a question in a forum. Looking at stuff for DSMs, hondas, and especially Focus's. The Focus engine is basically the same as ours and most turbo knowledge from there will work here.

I did wonder what that previous statement was saying!

I have a very knowledgeable friend (who's currently elbow deep in my clutch replacement) and he says that i'd be able to stick a standard turbo on to the cougar at a fairly low psi and still get over 200bhp outta the Cat!!!!

How much did you pay for your turbo Seawulf?

[pgtatx]

You're missing my very simple point...

You can't just buy any turbo with any flanges, and stick it on any car... you'll need to modify the stock header or an aftermarket...

It's not hard... I helped a frend turbo his ZX2 years back... We just bought extra flanges, cut the pipes, sent it to a shop to weld the flanges on, and bend up some brackets for mounting it, and we made some very simple piping (intake and exhaust). Location of the turbo had to be changed twice for problem with the oil return line...

Again... you can't just buy any turbo and slap it on...

[azervas]

Fair enough!!

What would you say was the rough cost to do that then???

So i can start saving!!! :biggrin: :biggrin:

[pgtatx]

My friend did most of the labor himself... I'll do my best to remember costs:

I don't remember what car the turbo was off of... I think it was a TD04-14b...really small, easy for fitment, oil and water cooled, was like $500. Then there was the used focus header, piping (every bend angle available), silicone couplers and elbows, fuel/water/and oil lines...

Most parts were bought used off ebay... including a rising rate fuel pressure regulator...

Total cost was around $2000 iirc... he never fully finished it, because he moved away and had to sell the car... but it did run just fine. Ran horribly rich though.

Thanks for the info!!!! :)

U don't want one of those. They run out of air before u start hitting ur redline....

[pgtatx]

On a 2L I4... the the TD05h-16g (big) will hold boost in higher RPM's and make some solid power. Big 16g's flow enough air for a 2L to make 300whp... as seen on Talons/Eclipses... even modded versions used on the WRX will make 300awhp... My friends Talon runs a Big 16g and dynoes around 315whp on a poor tune.

Just a question for you... I clicked the links in your sig out of interest. You list a Greddy turbo timer and a Boost gauge in your mods, yet you list no turbo. I also see no turbo in the pictures. So tell me... what's the purpose of a turbo timer and a boost gauge if you have no turbo and produce no boost?? Just wondering...

Because i had a t3 turbo kit on my ZX2 for a while. I blew a oil seal on the exhuast side of the turbine almost lost the engine, and also it was not smog legal in CA where i live, so i went a differnt route

I do take my comment back about the 16G turbo's, i read the post to fast, i thought he meant the t25 turbo's stock in the turbo Eclipse's

So don't come at me like i don't know my ****. I have rebuild plenty of Zetec engines to know my ****.

[pgtatx]

Yo chill... what's with the insecurity complex...

My post was rather friendly... "out of interest" I clicked on your sig. I noticed you listed turbo timer and boost gauge as your mods, but I saw no turbo. I was asking where you were going with that... were you in the process of adding a turbo, removing a turbo, etc... I never "came at you" with anything.

However on the flip side chill out... most people on here are rather respectful. I'm not like some new member who's just around. I've been here for a while. I have no reason to start anything.

Plus on a side note. My interest in your car, was since I used to work on my friends ZX2. He had mostly all the bolt ons you could have, and some body work. It wasn't bad at all. I tried to talk him into a turbo set up, but he didn't want it. Car was later destroyed in an accident. He was perfectly fine... but no more ZX2 for him.

I'm sorry, for blowing up. so after the turbo blew, i'm going with a JRSC. thier isn't a S/C for the ZX2 yet, so I'm tring to do a conversion with the JRSC.

Good luck with that... Always nice to see different cars getting modded out there. Everytime I see a Honda, WRX, EVO, Eclipse/Talon, mustang, camaro/TA, etc with work done to it... I just shrug.... they are all the same.

Obviously I own an STi... which makes me a hypocrite... but I wanted an AWD vehicle with some balls... so where else do you turn.

Good luck...

don't feel bad, I want thw WRX wagon so bad! but then. I've taken a couple of them at the track so I'm kind of fishing to buy one..

but hey im planning on a T3 setups soon... if i run a low psi like 8 would I need to do my internals if i have aftermarket cams. because i heard stock cams react better to boost than aftermarket be cause aftermarket cams cause i higher redline and boost plus higher redline plus stock internals equals huge problems. so my question is stock cams plus 8psi boost would i need internals?






I smoked an sti from a roll......... he was changing his tire and i waved:wave:

[pgtatx]

You need to remember you can shred the stock internals on an NA setup...

It would be a rare occurrence, however my point is, you never really "need" forged internals for most street cars.

People change their pistons (specifically) for lower compression from an NA to a boosted car, and forged internals will take a greater beating in case of detonation. Plus they can allow you to run higher boost presures an create more power with piece of mind.

You can do this on stock internals, but the internals won't last as long...

That all being said... it comes down to your tuning of the setup... moderate boost 5-7psi (8 is fine)... on a moderate sized turbo can be fine on stock internals if you're not looking to run leaner fuel mixtures and extreme timing advances.

Tuning is often the #1 reason why modded cars will fail later on... someone tunes on a dyno in 1 gear at WOT on a daily driven car... Then one day at part throttle in 3rd gear ist 4K, detonation occurs severly as the person pushes the pedal, and BOOM...

But remember... you WILL reduce the life expectancy of your motor... you CAN blow the motor right away even with a perfect tune and mild set-up... Always plan for the worst...

Stock cams are just fine...

Again... just remember... you're gonna get 100K out of a turboed cougar... you may not even get 10K...
