time attack turbo?

[rival]

Ok, so I have the engine fully built, now its time to pick the turbo and wastegate, mani, etc. so far I have an eagle crank knife edged, manley I-beam rods, and manley pistons, 8.5to 1. 272 cams, port polish etc. I am building this engine for a time attack car and have been considering the pt6262 cea ball bearing turbo. I want something to put out big power but not spool too late. If I go with this turbo, I am confused as to what wastegate would be needed. looking to run it around 40psi. Thanks for any insight or suggestions.

Correct me if i'm wrong, but don't you want a smaller turbo for time attack? Something along the lines of a 20g/50 trim?

You're correct, Ryan. The 6262 is too big big of a turbo and will spool way too late. Try looking at the size frame Ryan's suggested.

Fp3052 would be a nice one to look at, I believe they changed the name though. Something like DSM 76hta, its DBB.

Exactly, I mean you would prefer alot of boost at low rpm considering there is alot of turns and less straights. All in all, I think the 20g is almost a perfect turbo for your setup.

 

[TSITurbo95]

^ Exactly. Honestly, I would stick with a quick spooling turbo (evo3/20g), or even get an HTA68 or a billet 20g :/

40psi on a time attack car is just asking for it, i would recommend figuring out what class you are going to be competing in to know if you have any power/weight restrictions and base your decision on that. You should also look into the Borg Warner EFR series of turbos, if you want quick spook and good power.

good ol evo3 16g

Thanks for all the input guys, I have ran the evo 3 16g in the past, and it is an awesome turbo, I was just looking for something with a lil more kick to it. Its tough because there are so many choices out there, makes it hard to pick just one, .

Evo X 20G would be ideal, but you'd have to do some fabrication to get a working manifold.

Twin-scroll 12cm turbine housing for flow, still uses a TD05H turbine wheel for quick spool.

 

[viperlp01]

I am considering making a EVO10 bolt on manifold. They are bad ass turbos and reasonably priced. Plus FP and others make upgrades to the stock frame.

 

[JusMX141]

There's definitely a market....might as well do an o2 housing to work with most aftermarket downpipes while you're at it.

 

[rr06rs]

I'd say either an EFR8374 or gtx3076r. With a stroker of course...

 

[rival]

I decided to stick to the 2.0l. looking for the higher revs. I am going to look more at the 20g i think.

^ Good choice, I think you will be happy with it for a time attack turbo. . .
