what size turbo do I run on my 3.2 vtec? what size a/r? need a little extra power.

I think most guys run t3/t4 hybrid turbos......don't know the wheel sizes though

Mick, still waiting for your turbo to get done???

It's done.......just waitin for the scoop and engine cover to get done. I'll be pickin it up Saturday

What you need is a T3/T4 turbo with a 50 trim (compressor side) and a stage III wheel (exhaust side), with a .48 ar housing on the exhaust side.

Thats what I am running on my 3.5 Honda

MIne has a T/4 on it..

By all means DON"T let any of these turbo builders talk you into some thing other than the 50 trim. I had to wait for 5 weeks to get mine, they wanted to sell me another trim that had been on their shelves forever. They were going to give me one hell of a get deal....don't do it. The 50 trim is a older trim and is harder to get but it's been tested and proven. I've got this set up in my 2.3 ford and it's pushing over 400 hp at 22 psi of boost. This will give you some great hp with the right combo...just my .02

[attachmentid=106389]great info, thanks. what wastegate and b.o.v. should I use? anyone got parts for sale? I want to make this baby go!

here is a turbo on a 3.8L VETC. i can find out what turbo it is for you in the next couple days. @ 7psi im told it has 350whp

is it a 3.8 or 3.5?

Sweet set up I have the same in my limo ....Man you gotta get that fram filter off! they are crap I know I work for them LOL! K&N 1004 way to go..

Thats the same filter I use.......has the anti flow back valve in it

Looks pretty much identical to mine, must be another Don motor.. If it is the, 350 is pretty accurate. Mine made 400 at 5 psi and 530 at 12 at the flywheel.

a stock 3.2 with a .60 trim and .57 or .53 (dont remember) AR will net about 450 - 500+ fwhp depending on boost without an intercooler.

Every time I see these numbers in print on a V6 I just cant get used to it.

stock type s ?

Has anyone tried twin t-3's

how did your car run with the Honda last weekend Compa?

Ran good. Still have the high idle problem. Wasn't as fast as I had hoped.

from what I read from other posts on this topic I don't think my v-tec is working. Any honda techs in Tucson

When looking for turbos you will notice that most give 3 numbers; Compressor A/R, Turbine A/R, and TRIM. The way it is described in this thread is causing me some confusion. Typical turbo example is a compressor a/r of .50, turbine a/r of .63 and a trim of .57. Can anyone clear this up?

Example turbo can be had ALL day long on ebay for $200. What would a good price be on a used one?

This is the discription I was given from ITS for my turbo.

This turbo is a TO4E compressor cover with an E50 Comp wheel, it uses a dynamic seal with a 360 degree thrust bearing in a dry housing. Turbine wheel is a T-3 Stage 3 wheel with a .63 A/R non port housing.

How much power do you want? a good turbo for a stock 3.2 would be a GT35R on a .63 A/R or even smaller GT30R on a 63 A/R with a large waste-gate like the Turbonetics NEOGEN. Small turbo big wastegate works well as it spools quick and large valve still allows for good top end flow. Also next week Turbonetics is releasing the new GTK turbo's at SEMA that are supposedly top notch stuff good flow rates and quick spool.. So wait a bit to see . But don't run some old 70s 80s technology turbo such as a standard T3/T4 hybrid. The garret GT or the Turbonetics GTK turbos will make more power spool quicker at less boost.

GT30R should be good to about 500WHP will spool 10PSI by about 3100 RPM
GT35R are good to about 650-700WHP will spool 10PSI by about 3300 RPM

Also stuff like extrude hone and high temp ceramic coatings in the housings help with spool up sometimes by as much as 300 rpm or so..

my mid engine configuration will be much easier to run dual turbo. What size/type do you recommend

I'm not looking to make huge power, maybe only 5psi or so. I'd like to keep it as safe/streetable as possible and still run pump gas. What is the going price for the GT30 and 35 turbos? I'm trying to build this car on a farily tight budget, but if I can sneek a turbo in it for a few hundred extra...

Twin GT28RS aka the Disco Patato Turbo will be good in a twin turbo setup. Those turbos on a 350Z engine the VQ35DE 3.5L on a built low compression engine makes almost 425lb/tq at 2000 rpm and goes up from there to a massive 800WHP and 800 ft/lb tq though thats at 24PSI but you should still get torque to come on quick just don't run as much boost. And on a system like a haltech with a boost controller controlled by the haltech as TQ falls off start turning up the boost. Its TQ that brakes stuff not the HP and that will keep your HP claiming though the roof and keep the same FAT TQ curve across all RPM.

can this all be run with the factory computer with mods?

geeezz. They are 1100.00 on e bay for a garrett. Are the aftermakket ones any good? they are 350.00.

Uhhhhh NO.. stay away from the China made knock offs here are some links
China Turbo Failure #1
Manifolds made by the same company. SS AutoChrome. or XS Power Turbos. Stay away from China knock offs
Another guys project using china made OBX manifolds

1100 bucks.. Ya you should be able to find them for 950 or so. Remember Cheap is not good and Good is not Cheap . I don't want to brake down in the middle of the dunes. Some Ahole my set your ISH on fire... I saw it happen on Saturday night with some dudes truck..

The GT28RS is full ball bearing with like a 76% efficiency . That turbo spools up at like 2400RPM and will still make 400WHP on a Nissan SR20 2.0L 4 Cylinder at 8.5:1 Compression.

BTW where do you want your power band range to run??? You want low end TQ or High end RPM raw HP or very flat TQ curve across the board?

Anything is possible. Ya it can be done but there is no ECU tuner for the 3.2L V6 in the Honda that I know of. I will look around at SEMA next week see if I can find anything.. You will be using an FMU too add fuel a very crude and barbaric way to add fuel. I would go stand alone ether Haltech if you got some $$ or PerfectPower seems to have one for a good price the problem with Honda is that stock ECU/MAP sensor doesn't understand pressure. Its unfortanate that for the V6 you got no options of factory tuning. If you had a B,H or K series Honda engine Hondata has killer tuners for them I will ask them at SEMA if they will look into making a cost effective tuner for the V6 as it seems like alot of the sand guys use that engine. See what they say

cool. Thanks for your help
