Zero R

I can't quite spill too much, the owner had a very bad experience with his so called "tuner" after a very long time he was finally convinced to come here by a customer and have us do the tune. We netted him 250whp more than the previous tune, (yes it was that bad) He runs a 1.8ltr toy motor, alcohol, GT42R, He is just hoping to get the low 8's (8.2-8.3's)he thinks he should for at least this season, nothing fancy yet. Then he wants me to rebuild the whole thing around a 2.7 motor. I felt good the guy is a good guy, and he got the runaround for soooo long, when we made more power on turbo only, as he did on turbo and spray he just couldn't stop grinning, we will finish the tune after he makes a few passes tomorrow and hopefully get him his low 8sec pass. I don't follow this motor much my understanding is 7.9's is as good as it gets so if we manage a nice consistant low 8 I'm happy with it. I just can't wait to get started on the bigger setup If it were me I would be trying to stuff a 2JZ in there!!



It's a pretty neat little car

Turbodriven

I agree. Also the company in my sig is who engineers the Borg Warner units for folks like the link posted. They are working on the DBB version of the Borg Warners as well...

Turbodriven

They can be made DBB as well ........ Shoot me a PM. I'll send you the contact info on who you need to talk to. These guys are an engineering house for Garrett, Borg Warner, T-netics...etc. They can CNC you a custom unit pretty much of your choice and build alot of the race turbos you see out there.

How much HP do u guys think a 13B PP with a T04Z with a 1.35 housing would make at 30 psi with E85?

Im thinking about using a T04Z for my track car engine next year. And im in the progress of getting the parts for the PP engine. I was gonna use a T04Z anyhow, but i think a 1.35 exhaust housing would fit a PP engine better then a 1.15.

What do u guys think?

So what about the new VATN turbos , anyone have a any idea ?

my favorite turbo as of late is the BW s400 74mm inducer. the response is actually better than most expect i will be using this on my "street" car haha

Turbodriven

Yeah I'm moving up to the ST74 with the T4 housing and haven't decided on the turbine wheel yet. One of the local guys just tried the ST70 with the .80A/R housing for quick spool and its awesome. Crazy power and spools fast. The ST's turbine wheel is a touch larger then the GT42 turbine wheel and flows what the GT45R turbine wheel flows. So you get quick spool and big top end.

Marcel Burkett

Should I be looking into a BW turbo too ?

thats going to take alot of injector.... i mean alot

jantore

U don't say, already running 4x1680cc injectors now. Probably need to use 2 more 1680cc injectors.

But what worries me is backpressure in the exhaust with a too small exhausthousing on a PP engine.

JT

Turbodriven

Yeah, ask them about it as well. They make hybrid crap using all kinds of parts.

Marcel Burkett

Chris , U mind going into some more detail here , turbo specs and model numbers would be good .

Marcel Burkett

I finally ordered my GT45R from jason at the RX7 store today , should be in my hands by the end of next week !

Turbodriven

Good spooling turbo, but only major downfall is the lack of exhaust flow. the 12 blade turbine just barely outflows the 10 bladed GT42 turbine.

everyone keeps talking about the BW s4-- series turbos and how they "out spool" the BB gt4- series. what do you guys mean by this? boost hits earlier? how is this possible without the BB option. only reason i ask is because the BW (say s475, is equal to a 42 right?) is a considerable abount cheaper the garrett units.

Marcel Burkett

This is the same reason I almost got the GT4708R , I was advised against it though " for my needs the GT45 should be more than enough" , I mean really , if others are making 600 an700 + RWHP on a GT42 , I think I'll be ok. Maybe when I upgrade the turbine housing to the SS Tial one it will perform better ?

They don't out spool when compared apples to apples. I'm pretty sure I posted about this earlier in this thread(might be another). I have seen enough of it tested to know. If your building a drag car and have a two step spool is less of a worry. The wheels have sound/solid aerodynamics, and flow well though. The price difference is because your comparing a non-BB unit to a BB unit.

You'll be fine, you have more than enough turbo for what your trying to do. Too bad on the purchase I have some sitting here I'd let go for a real good price. Sold the initial ones I had, and now I have too many and I'm tired of staring at them.

Hi!

What price do u have for me?
I`am looking for a turbo for my setup, but don`t really no what to go for..

GT4508: direct bolt on upgrade for GT4202
When 1,000HP Isn't Enough.

Already have a 4202R and want more power? Here is your answer. We take a GT4508 and machine a GT42 Compressor housing to accept the GT45 compressor wheel, it looks great too!

Sean, you and I should have a chat. Maybe I can help you get rid of some of those eye sores you have laying around. Or perhaps I could "borrow" one of these for our *other* project.

Marcel Burkett

I paid $2500 for it , whats your price ?

Turbodriven

If you just have to have a journal bearing unit, then just go with the non-BB GT45F. Its the new non-BB version of the GT45.

Marcel Burkett

You were right Zero , that turbo is one HUGE **** ! Its not going to be easy getting it to fit ! but for it's size , it passed the FAN TEST with flying colours too !

Marcel Burkett

Anyone know what size restrictor is needed for a 45R ?
