Best Bolt-on turbo with pump gas for most power?

[v8s_are_slow]

Building my dsm around a T-28 right now but overbuilding it for when I upgrade the turbo. Want a bolt-on housing (FP race manifold), with a compressor that'll clear the water pipe, not take all day to spool, but still provide as much power as possible on a 2.0 setup.

I'm looking at FP turbo's but not sure about the spool, etc. They don't really say much. If you ask what my horsepower goal is, I'll say as much as freakin possible that I can get on pump gas. I know 2g's are tight on space so want something that'll fit. Really have my eye on FP's but not sure which one would suit me best. Opinions? Thanks.

If you're not looking to dent the water pipe at all, the HTA68 has your name all over it.

 

[v8s_are_slow]

I was thinking about that one. Wondering if they could make a compressor housing that exits like stock. I don't want the 1g style housing. I don't mind a small ding, but don't want a huge dent like what I had to do when I owned a SBR GT-13.

 

[Guzman08]

going on stock internals?? or changing them as well??

 

[v8s_are_slow]

They "will" be changed for Aluminum rods, crank, etc. Just trying to finish up with my bolt-on's 1st though. JMF Drag manifold, water/air intercooler, 3 inch i/c piping, side exit exhaust, etc. with Ecmlink.

DSM82.

Will give you the most power. Will be a little laggy on a 2.0, but should still see 20lbs by 5k. More than enough powerband to play with.

 

[Guzman08]

well you can get around maybe 550+ with a precision turbo. but of course after you upgrade your internals and fuel injectors. dont know if you want anymore than that . seeing that its a gst.

Yeah, that's a bit of lag there. Wonder about this one...

All the descriptions seem to talk about past turbo's and all. It says decreased spool but by how much? What motor? 2.0, 2.3, etc.? No estimated horsepower rating and all.

Don't want a Precision turbo. And not staying fwd. Have an awd tranny, transfer case, gas tank, and rear end, etc. Just saving to get an aluminum driveshaft and a few other parts and need the time to transfer everything over. Awd conversion is in the plans as soon as I finish with the bolt-on's (2 or 3 months).

 

[Boosted98gsx]

I run a 3582r (.82 a/r T3 turbine, while Fp's is a ~64) and I get 20 psi by 4200 on my 2.3.

Running the FP turbine housing on the 76 should get you similar results. And trust me, it's not too laggy, ESPECIALLY for a front wheel drive.

 

[TuRBoTaLooN]

I have an FP3150 (not in production anymore), but it clears my water pipe without having to dent it. So anything with the FP30 series housing should have enough clearance.

 

[JusMX141]

Wondering if they could make a compressor housing that exits like stock.

See if FP could cut you a 20G cover to fit the HTA68 wheel (the same cover the Green and Red models use). This would at least be a downfiring compressor cover, making piping easier and possibly only requiring a slight dent in the water pipe. Internally-gating the turbo would be much more difficult with the 20G cover, however.

 

[Gamble97]

FP Green or another 50trim. Pump gas king.

 

[dsm-onster]

FP3052. No clearance issues. Bolt-on. Plus makes sh!t loads more power than a 50-trim. And makes at least the same on pumpgas. Has been nough turbo to bend 6-bolt rods. So, it's plenty over the edge of the 7blot inn your car currently. And worthy of a forged build.

As well the hx35 7blade with either t3 housing option would do the trick. You will not have to dent the water pipe with the proper exhaust manifold (ERL) that will also flow ALOT more than stock. Even with the exhaust manifold upgrade the total cost will still be less than any other turbo out there even used that comes close. But that means you do away with your fp race manifold

I had a T-67 in a T3 with an OBX tubular manifold on a 2.3 and it spooled just fine. Think it was a .82 A/R if I remember right. Then got a fwd with a 2.0 and slapped on an E16g and it was great. Lots of power and really good spool. Netted me a 7.7 in the 1/8th. But I wanted to upgrade so decided to throw on the T-67 with the manifold I still had and spool was TERRIBLE!!!! It'd go through the entire rpm range before it spooled and had to shift gears before the power kicked in. I kinda wanna stay away from that again. I really kicked myself in the butt for that move cause I had sold my E16g to use the money for the bigger injectors I needed.

Anyway, wanna stay away from making that mistake again. Would like to go with a ball bearing turbo. Just not sure which one. Not sure what the spool times are. I know the HX-35 can get a BEP housing in a .55 which has netted people some good results. I wanna go with some bigger power but not so big that lag is terrible. Probably go somewhere between the 3052 to the HTA 76. Gotta find that middle ground for best spool and power.

And I'm not staying fwd on this thing.

 

[dsm-onster]

If a t67 wasn't that slow a spooling turbo for you, then a bolton hx40 should feel like a dream come true. It spools as fast as the fp3052 and has net more power and best mph considering weight than any other bolton turbo.

 

[v8s_are_slow]

It wasn't that slow on a 2.3 block. But on a 2.0, the T-67 was terrible. And a 2.0 is what I'm gonna build this time around. Wanna go with aluminum rods and make it a very light weight rotating assembly.

Not trying to turn this into a brand debate of any sort, but I think the Holset HX35 or possibly a BW S2xx in the .70 a/r T3 Bullseye turbine housing is right around where you'll want to be both spool- and airflow-wise. They're rebuildable in the event of a problem (engine failure, wheel damage, etc) where the ball-bearing FP turbos require cartridge replacement.

Good fitment and excellent block clearance for either turbo when using the ERL cast stainless manifold.

I'm sure the whiners will insert their quality contribution/suggestion

Oh trust me, I appreciate all feedback. I won't be knocking any turbo. But if I get a Holset, it'll have a BEP housing and a FP manifold though for sure. But guessing the BEP housings take awhile to get? Read in another thread where the guy was waiting on the housing he ordered back in January. I don't like waiting that long for a part that's ordered.

 

[JusMX141]

The big concern there is the HX35 has a huge compressor cover which would most likely interfere with the water pipe drastically when used with a bolt-on housing and a manifold which places the turbo near the stock location.

We had to smash the water pipe on my buddy's 2G pretty decent to get a Frank 5 20G to fit, and that cover is much smaller than the one on a HX35.

 

[v8s_are_slow]

Hmmm, makes me wonder what turbos can be ran/not ran with that manifold then.

 

[v8s_are_slow]

Okay, scratch the FP idea. I've been reading a TON of threads about Borg Warner turbos and see nothing but good good info regarding them. I like the power the S366 can put down with the short amount of spool it takes to reach the boost levels it makes it in. Just wondering about the difference between the S366 and the S366XL. They seem to be pretty close so wondering what the difference is.

The other thing I'm looking at is getting a top mount manifold to make everything fit okay. Punishment doesn't make them, JMF does but only for 6 bolts, and Shearer makes them but I'm only seeing T4 divided manifolds. So that leaves me wondering a question (which I've searched). Which would be better to go with? A regular T3 manifold in the downward position (which would have me worried about clearance issues), or get a T4 divided top mount manifold? The T3 turbine housings are smaller than the T4 divided housings so would think it'd be better for spool. But does a T4 divided spool faster than a T3 housing that's smaller or no? Say .70 T3 housing versus .90 T4 divided for example. Thanks.

 

[JusMX141]

The S366 is a HUGE turbo. Even the S258/259 is capable of HX40-like airflow and 500+whp; you shouldn't need any more than that.

Seriously? How do you expect to get correct advice when you're so all over the place?

 

[v8s_are_slow]

I see what you're sayin. Spool is the biggest issue really cause I want to keep it streetable and just don't want a turbo like the T-67 I had before that took FOREVER to spool. And the main reason I was wanting a bolt-on housing was because that I know with a BEP .55 ar housing, it was gonna give me the best results for spool. But then I started reading a lot about the BW turbos and the spool they get with turbos like the S259, S362, etc. and it's really not that bad, and how with a BEP housing you'd start getting the choke effect once you got on up there in horsepower. Jusmx141 mentioned the BW turbo's and I started reading about it. A lot. I wouldn't really say I'm all over the place. Maybe more so that he just opened my eyes to these turbo's. My mod list isn't changing any. The turbo and the size AR housing I go with is the only debate I'm really having right now. That's about it.
