Questions: turbo rebuilds, BOVs, and turbo manifolds

As many of you know i bought a turbo'd car not too long ago, Car has been boosted for the good part of 4 years. So obviously there are some issues to take care of. Some rebuilding and changes have to be made.

1st: Turbo rebuild. Does anybody have any experience with a shop that can rebuild a Turbonetics TO4E, Its a ball bearing turbo i know it will be a little expensive. im not looking for a random shop but somewhere worth while. The turbo is still in good shape and boosting fine i just want to go ahead and knock this out now.

2nd: Blow off valves. Currently on an SSQV. It has a flutter and im not too fond of flutters no matter how "cool" it sounds. And on top of that i really dont like the SSQV, what else would be good, Synapse is high on my list, and i love the sound of the Greddy Type R

3rd: Turbo manifold and Downpipe. The way this one is designed is just unacceptable for me, It is atleast 1.5 inches lower than the crossmember. most of you have seen the height my I30 is at and the downpipe on this car has worse ground clearance then my I30. So i need options and suggestions on what to do to change this.

ATP turbo, pte or forcedperformance.net are the only places that I know that rebuild turbos.
I had a HKS SSQV and I hated it. I had a greddy type s and it was ok. My dsm I run a tial and will run nothing else. Tial or fail.

I am going to send mine back to the company for the rebuild it may not be the cheapest but I figured they made it

If nothing it is wrong with it I"ll buy it pending the price. Mine was a crisp lazer beam type sound and I liked it. The only time it had flutter was when I install the check valve and it turned out that the valve was too restrictive

3rd: Turbo manifold and Downpipe.

Depending on your setup I can make you a downpipe that run underneath the oil pan or if your not in a rush I can make you a feed and downpipe with a custom motor mount like mine. The feedpipe run over the cross member like my old one but this time the downpipe is going to run back across the motor mount and cross member and under the oil pan. The setup will not hang below or at the most a 1/2 inch below the crossmember. The only problem is once it crosses the motor mount it will be reduced form 3 to 2.5inches but I am only looking to push around 350-380hp so it won't be a problem.

btw my old setup had a 3inch downpipe and I was lowered on s-techs and the only time I scrap was when I ran over the concrete curb thing to cross over to the over side of the highway

i'll check those guys out.

There seems to be a fierce battle between synaspe and tial users, which leads me to believe the are both of equal quality until one proves the other wrong.

Im not looking to spend over $500 on a rebuild thou, and turbonetics wants $765, i looked at that and was like i can add 300 and some change and get a brand new turbo. i have been talking to companies such as Blaast performance and i have heard quite a few good things about them. But im still shopping.


I dont think anything is wrong with this SSQV but when i do get ride of it i will be looking for around $160 shipped.



Ground clearance is very important to me, because of how low i want to run, i have been looking into oval piping for the downpipe just to make sure i have enough clearance. Everything has to sit a couple of mm above the bottom of the crossmember. But yea i would be interested if you could PM me a price and what you can do.

DD height of the I30:




It is tucking the tire. i plan to raise it alittle so im not going through to many axles but i dont want to worry about ripping off the exhaust.

The Synapse is prob the BEST and most reliable BOV out there.

ok I see your point with a 3inch dp you'll be shooting sparks like this guys on bags. even with a oval pipe you'll need to raise the car. to stay that low you'll need to run a dp over the tranny and start and down the firewall or back across the cross member and under the oil pan. only problem is I am pretty sure that I30 has abs which means you will have to run a 2.5inch dp to clear everything if you plan to run it over the tranny.

what does the feedpipe look like I can have a idea how everything would look and where the turbo will sit

i found some oval piping that is very wide but shallow that might be able to do the job of keeping everything where i want, lemme go outside and lift the car and take some shots.

Lol I actually use same spot to jack my 3rd gen up sometimes. Oval piping is great. I need to order some for my downpipe. Since my downpipe goes behind the motor between the firewall and forced to use only 2.5 in"

For the BOV, I really like my Tial 50mm and I would recommend it. I tried a SSQV crap and hated it, didnt even vent alot. Had a Turbo XS RFL for a long time, it worked great but they are designed to leak, no diaphram just metal to metal contact.

with a turbo of this size i dont think 2.5" piping is a good idea, it looks like 3" oval piping should be able to snake its way through to go inbetween the firewall and motor.

This one probably just needs alittle adjustment but i have never been a fan of the SSQV, Im seriously considering the Greddy Type R.

Ya my turbine uses a 4" vband so I really need to get some oval piping ordered. Have you looked at the synapse syncronic BOV?

ok a pfi kit

you will need to either make a new feedpipe or cut the turbo flange off and reweld it with the turbo turned around to run the dp between the firewall and tranny

it would be easier to either make the dp over in oval pipe or notch the motor mount and run the dp back over the cross member and under the oil pan

im already convinced i will need a new feed pipe, I dont like this one, to many bends, curves and unnecessary piping. i would like to keep everything short and sweet.

but will there be enough room? unless the feed pipe is oval aswell then they can be flipped sideways and run next to each other. theoretical 3" piping from what im seeing in oval form is 2 1/4"x3 3/8.

looking at the pic again, yeah the feedpipe hungs alittle low too

your right it seems the easiest thing would be to just make a new feed and dp and sell the pfi setup since the setup would b fine for someone who is no slammed
