Go early open on both ports, it only hurts from idle to 2k or so and adds tons everywere else, and who the hell drives in those rev ranges anways (2k and below)? I'd also port up on both ports, the primay more so then the secoundaries. Go mild on the late close. On the exhaust, go slight early open and slight late close. Should be "D" shaped. Sinse you have the engine apart, swap out those horried REW exhaust diffusors. Do a search, theres several ways to get them out. I use the sheet metal screw technique. You can get good TII or RE sleeves from club members who have trashed housing cheap or free!!

More of a question for RacerXtreme7,and sort of thread related.
This came off a late 80's diesel truck Garrett T04E turbo. A diesel shop told me it was "T04E" .7 cover with a 4" inlet. It's not a surge cover as there are no holes that are ported/bypassing the smaller inlet into the cover. I plan on machining it out and using it with a 35R wheel I have. The questions I have is, Would this be considered a surge cover of sorts, and would there be much difference going to the bellmouth T04S cover flow wise. If you look at a "S" cover and this one they almost look the same shape except that this "E" cover doesn't have the bellmouth shape.

The GT35R does come with the T04S cover. I'd recommend the T04S cover as the bellmouth design will flow better. This particular T04E cover is just a bastardised Surge cover without the machining done for the ports and the inner shroud gone. I guess if your on a shoe string budget, it will work, but if your trying to build a better turbo, get the T04S cover. If YOU plan to do the machining, why not go ahead and machine yourself a bell mouth then bore this housing and press into it the bell mouth? There are a few old school Garret T04E covers like this floating around for OEM Desiel applications.

I am just going to throw this out there, and see what I get. I drove an FD for the first time today. It had the stock sequential turbos running stock psi. I was blown away, I loved it. (the sequential setup was working properly) Is strapping on the stock REW turbos to my engine a bad idea for a reliable 300-320 rwhp?

Thanks

Edit : I think I just answered my own question actually. I don't think they are rebuildable, and are unable of making high power without taking them out of sequential mode correct?

You'd be better off single. Finding twins that don't need rebuilding isn't easy, finding twins that don't have cracks in them isn't easy, making them work sequuentually is REALLY hard seeing you don't have an FD (OMG the RATS nest and solenoid packs EEEKKK!!), the T04E will have very simular response (especialy with a 3.5" exhaust) and your engine will hold in less heat, be overal more effecient and thank you for it. The single is lighter, and less complex. Not to mention rebuilding a T4 cost around $75.

Ok, that is what I was expecting to hear. I just needed to hear it.

Yep, this is the budget turbo build attempt . T04S covers and backplates are $200+ bones(not even factoring the shipping,taxes,etc.) new while this was less then a 1/4 of that. Friend is doing the lath work so I'll see how much extra work it is to press/interference fit a plug and machine to a bellmouth shape.Most likely I'll just radius/fillet the main inlet, and call it a day.

Masterpower uses this same 0.7 A/R "T04E" cover on some of there turbos also.

I am interested in buying a used t04s turbo because it is the right price, but I am worried that it might be too big and laggy. It is described as "Garrett TO4s turbo: .70/.96AR with the upgraded GT-Q trim wheel" I have never heard of this GT-Q trim, but I know it must be larger than the O, and P trims.

Any feedback would be greatly appreciated.

Thanks

Yo, yo! The turbo I'm selling was originally purchased here:

http://cheapturbo.com/

Look under "Mazda" and you'll at least be able to get a better idea of the specs etc. from this particular turbo.

RacerXtreme7

iTrader: (2)

The GT-Q turbine is a newer Garrett wheel... of the GT flavor. Its been said to spool simular to the older p-trims, and flow like the older Q-Trims. Great turbine, might be a bit over sized for a 60-1 compressor though unless its a Super 60-1 with which I' don't recall who makes that wheel and if its even available anymore. Your original power goal of 300~320........ you keep picking bigger and bigger turbo's. If your looking to make 400 to the wheels, then this is your turbo. If you want big block like linear near instant response with a 300~320 power range in low boost then pick something already disscussed.

Ive got an idea... not sure if youd be interested...

I'm looking to upgrade my Garrett T4 T04B v1/v2 trim compressor | .84 p-trim turbine 3inch VBand.
This turbo has Dyno documents prooving 360rwhp at 15psi on an s5 Turbo motor with mild intake porting, 3inch exhaust without a cat, and 340rwhp with a bonez cat.

Would you like to buy my turbo??? It may not be quite as good as say a T04E, S, R, GT, or T-6X series, but it will durly get you down the road. It is of course used which will be taken into consideration pricewise.

PM me if you are interested... Pricing available.

Hello. I know I should just get a t04E from turbonetics for like $750 made just like I need/want, but I was offered an interesting turbo today. It is a PT67, and when I look for it online it says it has a .70 compressor, it is ball bearing, and has a .81 combined AR. Semi perfect. I looked on the forum and found a lot of people putting down 400-500 rwhp on 15 psi, but I couldn't find anybody running 10 psi or less. I was thinking that maybe it might still spool decent since it is just a .70 compressor, and I thought that t04s (60-1) is the same size. I got offered about the same price as the t04e from turbonetics for the new ball bearing pt67. Is there any way this turbo is like a 60-1 like I am hoping? or is it much much larger?

Thanks

nevermind, I did some more research, and it looks as though that turbo is quite big after all. Wakes up after 18 psi, full boost at 4,000 rpm on a half bridge. Not something I am looking for.

Turbo nomenclature can be confusing. But if it says "67" it MAY mean the inducer of the turbo compressor wheel. The 60-1 wheel has a 60ish (59 really) mm wheel, which is significantly smaller.

Maybe you need an Apexi Rx6 turbo, or a T3 GT35R.

Wow i learned quite a bit reading through this thread. Good info.

just if anybody wonders, I ended up going with a 60-1 with a .84 AR water and oil, with v-band and 360 thrust bearing for a little over $1000. Kinda sucked, compared to what I was thinking I was going to get, but at least now I can forget about it and continue on with my build.

The t04e I still think is a perfect turbo for the 300-320 range, just I could not find anybody that had some in stock and could ship it out asap. I ended up going with cheapturbos.com.

On a ported 13B you wont be dissapointed with that 60-1, although it can be a tad laggy for auto X. Its very simular to a GT35R in response and power.

Back from the dead sorry. My t04s is going out. Some pretty massive shaft play, and it was / is blowing smoke.

I was wondering if there is anything new I should be looking at? I am thinking about grabbing a PT67 because it is local for a decent price, and putting my divided .84 p-trim on it. Might still be pretty laggy.

What about the new billet precision turbo 6262s turbo? I was decently happy with the performance of the t04s, even when I put on a silencer it still had decent response. I am just checking to see if there is something else I should be looking it now lol.

Thanks

Why not just rebuild it? You sure killed that thing quickly esp for only running 11psi.

TweakGames

iTrader: (3)

I don't have time for down time. I will rebuild it while I run the pt67. I think it's because I didn't have an oil restrictor on there.

Any recommendations on oil restrictor for the pt67 with my RE oil regulator? (90 psi warm 100 cold)

Thanks
