Need new turbo... Recommendations please.

[Cronopoulos]

I havent been able to dial it in just yet with my ebc, going to switch to my smaller wastegate actuator as the holset one seems to be pretty stiff, turned up it will boost 20psi. Ive got it somewhat settled at around 15-18 but i didnt drive around enough to get it perfect.

Generally id like to set the low setting on my ebc to around 10psi or so, the high to around 16-18 psi

Where can i find a split pulse manifold?

I think you can easily modify a Revshift manifold to work well for split pulse from what I've seen. When you turn the boost up closer to the turbo's efficiency window does the spool get a little better?

Also i could not find a correct restrictor so temp im running my -4an line to my turbo, oil pressure is about 50-60 psi when you get on it, from my reading too much oil pressure can increase spool time? But that badly?

Personally, id rather switch the hotside or buy a different turbo that fit your manifold rather finding a manifold to fit your turbo. If you can modify your existing manifold, go for it. I would have to download the PDF for the Holset model you have, id say nothing over 70psi and you should be ok, just make sure shes got at least a -10 drain or bigger. You would know if you were blowing oil past the seals haha..

Need to do more fixing and testing after work but I found a pretty substantial boost leak do a leftover piece of bracket on then inner fender rubbing a hole in an intercoolr pipe


Will report back later tonight

Ok fixed leak... Much better!

Will do more toying around later. With a correct tune for this turbo I should he spooling quicker.

Looks like a pretty good buy sir.

[FLG]

Seems so.

Def need a re tune. She's leaning out under boost and running rich off boost.

How does one tell if a manifold is the split pulse or not?

[jaywood]

That ^^^

Seems to be a lot of knowledgeable people on here ;) ... But yeah, your most likely seeing a lot of turbo lag due to the manifold not being twin scroll.

[jaywood]

He fixed the major boost lag already...it was a leak in a coupler. Twin scroll would definitely help spool up time, but not 100% necessary

Yep and the fact that it's not tuned correctly. Been waiting on maximum psi to get back up and running so they can tune her.

Any updates, hoping you are making some serious power now!!! :)

[FLG]

Max psi is busy and I don't feel like waiting.

Headed to "the shop" in Norwalk ct. They had originally dynoed the old build and the owner has a thing for turboed e30's

Scheduled for next week wed 9am...will post up the numbers when I get em.

Hi dont want to highjack this thread...but since a lot of the turbo gurus are in here right now!! I was wondering if you guys could recommend a Holset turbo for my twincharge project? Been looking for a while right now am leaning towards a BIG monster HX45-55... and hopefully a good deal somewhere..!

My apologies again for posting in here...I dont want to go to 30tech either...

[FLG]

Well good news and eh news.

Good news is it didnt blow up and made good power...bad news is stock fuel pump isnt up to snuf so we had to cut it short at 14 psi.

We made 330whp @ 14psi

Figure go with a Walboro 255 in tank and a 044 external?

Or just a 255 in tank and in line?
