your probably gunna need oil lines unless they come with the turbo, and the oil filter is optional, you dont need it but if you want it go for it, i have one but thats just cause i have a 420a and an expensive turbo that i dont want to get fucked up.

HKS SSQV BOV or a Greddy Type S, i like both but i use the HKS

i believe not but i am really not positive...

you can get a O2 eliminator, correct me if i am wrong but i think the O2 housing is cheaper

i use 550cc injectors and they work really well, you also might want to replace the fuel pump with a Walbro 190 or 255 lph, 190 would probably be perfect for you.

The EVOIII will bolt up WITH the 2G install kit they also sale there at slowboys if u have a 1G its a strait hook up. your options depends on what you are looking for out of this turbo. and yes the housing is cheaper. i run a 1G BOV with crushed top or you can getthe greddy type s 1G is the best(i think) fuel injectors u dont need right now UNLESS u have a boost controler if u have 1 i would also go with 550 OH wastegate the EVO is externaly gated

Good luck on your car

MY BAD I SCREWED UP THERE ITS INTERNALLY GATED SORRY ABOUT THAT

thanks for the help

There isnt as much porting to do on those turbos, be sure to talk to the SBR guys about it before you order. Definitely do not go with a larger flapper. Go to dsmtuners and search for a thread called "wastegate blowing open info" using my user name for the reason why. Nevermind, here it is:

Be sure they know you are keeping the stock valve and you want the porting focused on reducing creep with stock flapper. An external WG will be an awesome investment even for a 16g, but its expensive. The pros are you get rock solid boost control, and when you upgrade to a bigass turbo someday, that part of the modding prcess is already behind you.

I would stick with the stock manifold (2g) or get the EVO if you do need one. Same for the O2 housing. No real need for an upgrade, but if you do go with the EVO (kind of a pain in the ass) or a tubular one (not cheap) you can get marginally better flow and slightly faster spool up.

I would suggest a 1g BOV. More than enough for a 16g, and the money you save can go to other requried parts, like the injectors. The "best" BOVs from what I have seen are the Tial and SARD, which are just ridiculously well designed, and will not leak. But you need a MAFT or VPC to run them correctly.

For race gas use I would suggest 550s. If you plan to try to make good power on pump gas (FMIC etC) I would step up to 660s, taking the spotential risk that you may not be able to lean out far enough on race gas. In reality though, 15-20% should be enough range, assuming SAFC. If you do MAFt or MAFT and SAFC, definitely go 660s, because you wont have the +- 50% limitation of the AFC (660s require 32% of that range just to adjust for the size difference).

Dont be afraid to talk to the guys at SBR. Chances are if you start asking questions they'll chew your ear off. And shop around to. At this time, SBR has the best pricing on that turbo as far as I know. But its always good to check out the other reputable turbo shops. I would only buy turbos from Buschur, SBR, FP, AGP. Think thats it. Your call. Good luck with it

once again 95 GSXracer saves the day !

[Afrokid]

I found a site that offers most of the parts im buying, and after seeing your post about internally gated turbos i have decided to get an external one. They only offer Tial Wastegates. I've read various reviews and they seem pretty good so i will most likely buy one of those. Except i don't know what size to get? They offer 3 sizes: 38mm, 40mm, and 46mm? Which one should i get?

Wise choice It all comes down to where you are going to mount it. If you are going with a manifold mounted gate, you can go a little smaller. I use the turbonetics deltagate, which comes out to 32mm (I'm upgrading to the Tial 38HP), and I can hold spring presure (13psi) to redline. If you are going with a O2 housing mounted setup, you may want to look at the 40ish one. But, now that the 35 has become the 38mm, that may be enough right there.

It also depends on what turbo and what boos you plan to run. ITs a common misconception that you need a certain WG to support a certain HP (which is BS) or you need a bigger WG just because you have a bigger turbo (also BS). What matters is how low do you need to be alble to set boost relative to the size turbo you need. For example, you would need a much larger WG to run a 500 whp turbo at 13 psi than you would need to run a 16g at 13 psi. So lets say you plan to run a 20g or larger turbo, and will never set boost below 20 psi, you wont need much wastegate at all. In my humble opinion, people that want to run these big turbos are on crack anyway. If I can run 25 psi daily on pump gas why the hell would I ever go below say 20 psi? Thats the general idea.

The next thing to consider is what spring pressure do you need. Keep in mind that you can never run boost below the WG spring pressure. Boos controllers can only raise pressure. The general rule here is to run as much spring as you can get away with on pump gas. Again, in my case, I run 25 psi daily, so the largest spring (21.75) is what I will use. Another ocmmon misconception is hey, I'll get the lowest spring they make just in case I ever want to run low boost. The problem with that is weak springs will allow the WG to "blow open" just like the internals do at high boost. Al of your parts need to be a well matched system. Theres no magic to it, it makes sense that a high boost car should have a strong spring, and a low boost car can use a softer spring.

Hope that little guide helps answer your questions. And Tial gates are probably the most widely used out there, a fine choice. The biggest consideration is where/how to mount it Good luck.

23.20 psi

[NeonblueEclipse]

will it be for town driving or racing ???

[Afrokid]

both, me and some of my friends are starting to race, i got an eclipes and they have a Crx

[JoeWagon]

Well, like GSX racer said, get a spring that has the least amount of PSI you will ever want to run, but also consider about the WG opening because of a weak spring. First thing takes priority though, you cannot run lower boost than your spring, so decide what boost you want to run for a lower-boost application, like street. I don't know how much PSI an evo 16g can run (anyone know?) but there isn't a lot of sense in setting it low anyway, if you can do it. If the turbo can do 24psi, i would go with the 20.40, but it's just a guess.. it wont affect much anyway no matter what spring you use at those ratings near 20.

thanks for the info
