T. Timer basics

Hey guys.
I bought my first eclipse yesterday. It's a 1990 gs-turbo. I really like the car. It's completely stock and has 160k miles. I know, kinda alot but I bought it for 950 with a brand new cat, battery, belts, and a bunch of other replaced parts. The car runs very strong and I really like the kick of the turbo at higher rpm.
I read in a few places that it's a good idea to have a turbo timer on these cars. I already purchased the wire harness for this model but I don't know which timer to buy. I am looking at the ones on ebay and there are some for $30 and some for $100. What's the difference between them?? From what I understand, a turbotimer is just a simple timer-relay, period. Would the cheaper timers do the job for me? I don't want anything hardcore and I am tight on money right now so let me know what you think.


The same goes for the BOVs on ebay. There are some cheaper ones on there and the real expensive ones. I already bought a pressure regulator but I also want an aftermarket blowoff valve to get that nice sound when shifting. Would it be ok if I buy one of the cheap ones? I tried searching for similar topics but I couldn't find what I need. Please help.

Most popular turbo timers are the Apexi and the Greddy ones. I have the Apexi, and it works just fine. They are all the same, except some have other features some don't. It's up to you what you like.

For the BOV's, I know some people have said the ebay ones work just as good, but I went the safe way and got a Greddy type s. You will want to stay recirculated, so stick with either yout stock one, or any Greddy, or even the HKS SSQV with the recirculation kit.

i don't know anything about the turbo timers but for the BOV's i've heard the nockoffs are just as good as the normal ones

I would stick with a name brand blow off valve IMO. Why take a chance when you don't need to. However, your bov should be fine. On a side note, has your engine been rebuilt at all? Your car has alot of miles on it. Personally if it was me I would think about a rebuild or something along the lines. 160K miles on a dsm is alot... :2cents:

a 1g bov is just as good as anything to an extent

Well the car has all those miles from freeway driving. The the guy I bought it from was a 40-something year old financial adviser or something like that and he used to drive to L.A. and back a couple of times a week (350 miles each direction). He definetely did not drive the car harsh since he is one of the slowest people I have seen in everything he does. He bought the car brand new, with only 2 miles on it and has had ever since. The engine sounds perfect. No lifter ticking or any other noises. The turbo is strong and spools easy and seems to push the stock boost just fine.
One problem the car has or will have soon is with the shifting. I don't think it disengages very quick since when I shift from first to second in a pretty fast manner there is a loud noise coming from the tranny. I read on a few places that it's a problem a lot of these cars have.

It never hurts to run a compression test and do some typical maintainence, give it a good tune up.

The tune up I will do this weekend. I will change whatever looks old along with all fluids. I will definetely make sure everything is fine on the car before I start boosting or anything like that. I just want to order the parts so I have everything.

I think I have my mind set on a BOV. It is a dual port one, and it can be connected to the intake and it can also be atmosperic and I can adjust the ratio between the two. This way I can still get the nice sound and not have my car acting up. Sounds like a good idea? Anyone use these?

Post a pic of it, I've never heard of a bov like that. I have a GReddy type-s and its pretty damn loud and its recirculated

I've heard of the dual chamber BOVs before but they seem like junk to me. I would just spend the money on a good aftermarket one like GReddy or Apexi.

IMO you should save your money and just crush your stock bov and spend your money on other mods

I wouldn't worry about a turbo timer with a stock turbo either, spend that money on other mods.

your turbo is water cooled so you really don't need a turbo timer. Just don't turn the car off right after you boost. Stay out of the turbo for the last 10 seconds and youre fine.

and PLEASE recirculate your BOV, search on tuners if you must, but there is no reason not to in your case.

agreed

What do you guys mean by Recirculate? Not to use an atmosperic one with the wide 'whistle' but one that has a pupe going to the intake? Are those loud and how do they get the sound out if they are? Can you post pictures of the types you know for sure are correct and still sound nice?

Greddy type -s, type-rs, and type-r, HKS ssqv with the recircultaion kit, turbo xs has a few, turbonetics has one, http://www.slowboyracing.com/shop.php?sid=PHPSESSID=a96815bd987b863f8cf270e466d c0994&cat=466&PHPSESSID=a96815bd987b863f8cf270e466dc0994 look for yourself and use the spell check next time

I apologize about the bad spelling, I was doing a few things at the same time.
Well I really like the ones you linked me to but those are expensive and I don't want to spend that much money. I am mainly looking at the ones on ebay. I bought the car for $950 and I really don't want to add a blowoff valve worth $250 on it. Can you give me a link or links to some BOVs on ebay that would do the job? Thank you for all your help, btw.

If you dont want to spend any money on a BOV dont. The stock BOV on your car is as good as 85-90% of the BOVs on the market. Save the money for an exhaust or something.

I am running an HKS Type-II TT. I like it it was kinda expensive, maybe around $120, I dont remember it was a long time ago. It has some cool timing features like 1/4, 1/8, 60ft, 0-60. But I really dont think a TT is something that anyone needs. If you driven the car hard let it idle a minute or two (or 5 what ever you feel like) before shutting it off, other wise dont worry about it. I say save the money for more important mods. my :2cents:

95_GSX is right, the stock 1g bov is perfectly fine and works just as good as anything else. Take the money that you were going spend on that stuff and put it towards a downpipe or catback or an intake or something of that nature

You are right about the BOV guys. The only reason I wanted one was for the sound when changing gears but I guess that's not so important.

I've heard plenty of 1g bov's make loud wooshing noises.

Then how come mine doesn't do it?? What do I need to do? Would it start doing it once I raise the pressure to 14-15psi?

I started to hear my stock 2g bov after a filter and hard intake pipe.

hmm... i am going to have to replace all those things and hopefully it will get louder. I also want to hear the spin louder. A friend of mine has an Audi RS6 (4.2L with Twin-Turbo) and you can hear the turbos spin so nice and loud from pretty far away and his car is stock.

intake and exhaust will help that. so will hard intercooler pipes

Agreed, I bought a used HKS ssqv BOV for 150 shipped off somebody from ebay..I also was a new DSM'er at the time and wanted to hear the cool swoosh sound, then I found out it was bad for the engine, so I got the re-circulation kit for like 30 bucks...and as a matter of fact, I liked the sound better with the kit... But I wouldn't buy a BOV unless you get a really good deal on one like I did...spend your money on the basics 1st, then worry about the BOV down the road cuz u really don't need it right now.

Agreed. I am not even looking for one anymore. :)
