Well I am currently running a stock evo9 turbo at 28psi on e-85. Making about 400/400. I am still on stock block and head. I want to keep the stock block so I was looking into a turbo that would make more power up top but keep torque down so my rods will be happy. I was looking into the FP, MAP, and CBRD turbos but cant decide which one is right for me. I don't want it to spool too fast so it builds torque too quick, but I still want decent power up top. Any suggestions?

HTA FP Green seems to be the way to go, from what I've been reading it seems like a great turbo for anything from stock blocks to built LR2.4's.

 

Im in the same boat. Gonna go 440ish whp and keep tq low wiht only performance mod being a new charger. I can't justify paying what fp wants for theirs. As of now im looking at the precision 5857 bb. ya it'll be later spool but going from a boosted honda where the power never stopped coming on to a stock turbo evo where spool is too quick imo and power flattens out to much is why im looking into the precision ya it'll have later spool but seriously why do you need 14psi in third at roughly 3500 when racing you'll be at higher rpm. plus its not over priced.

 

some precision stuff https://www.evolutionm.net/forums/ev...862-t4-ts.html

 

Red, black, green, ef2, ef3,ef4 but most of all a supporting mods and good tuner to keep the tune safe.

 

What is your power goal sir? Pump or E85?

 

I'm running a ef3 on stock block as couldn't b happier ,,

 

You have PM.

 

These turbos are great aren't they I like my ef4 on my stock block, can't wait to build though.

 

Thanks for all the input everyone. I will probably be running e-85. I would like to be around 450whp or a little more but I want to keep torque under 400 to keep my stock block from exploding.

 

On E85 450whp (Dynojet) is attainable with our EF2 and will retain stock like spool If you feel that you will ever want more than 450whp though I would recommend the EF3.

 

Nobody has mentioned the bbk yet, iv seen people with great results with it on e85 on stock blocks

 

With upgrading the turbo to any of these mentioned. I don't think your gonna keep the torque under 400. It would prob be in your best interest to get a "slower" spooling turbo. My recommendation is ef3/4 or red/black. I think bbk is outta the question since the spool like stock. If I were you I would without a doubt go ef4 or black.

 

I would agree being I love my ef4 even on stock block and a hindered tq curve to keep it safe. Car is flat out a blast to drive.
