red1993gsallmt I'm assuming you're using a BEP Mitsubishi .55 A/R flanged exhaust base off of your picture but please be aware several people have had problem with the BEP bolt-on housing.Although you've improved the turbo oil flow some argue that .55 A/R is too small and creates a lot of back...

I don't believe a 91 is 23 spline, only some 90 or at least the early 90s are 23 spline. There maybe alignment pin missing if not that's the way a welded center differential work along lack of traction making it into a 4x4, all four wheels spinning at the same time, instead of a AWD, shorter...

I commend you on that exhaust. It looks very clean but if you're looking for a 4" v-band side mount exhaust I have one available. I cannot running it anymore after moving back to California.

Classic example of that! If you haven't ran anything but FIC than how is your comparison based?my98gsx, who really is the manufacturer of the FIC injectors and does FIC actual flow better than Denso because Denso ALWAYS flows better than what they are rated for.But if the fact that FIC is...

It's all about tuning, don't ask the question which is 'better'. That's just a run-around on what people say and think. Obviously if you have one instead of the other you would this it's better...Which is better... HKS cams or Kelford cams, JM Fab SMIM or Magnus SMIMI didn't bother to do...

16cm divided T4 Holset HX52 and the twin-scroll manifold makes a huge spool difference!

Everything is streetable in Indiana but everything changes when I came back to California... so I parting my car out but this is easily a 9s and capable of 8s. I don't how it is in Oklahoma.

Amen to that!I've gotten offers from $300 to $400 on my twin-scroll T4 Holset HX-52 turbo kit by newbs thinking that it is possible to bolt this turbo kit and make 900 AWHP and a stock engine and a stock transmission... probably an AUTOMATIC!!!BTW - you'd probably be better...

Seeing the same boost-to-rpm range as bwhite.Twin-scroll setup works wonders for a big turbo low boost-to-rpm range and mad power! Albeit I was having problems getting over 27 psi because the head was lifting and the coolant was surging out from the overflow can.

Made 598.8whp/437.7 lb-ft at 27 psi then the head started lifting if I went high boost but that differs when you're running a single scroll.

I was in the HX-52 business but since I move back to California I drop it. I had a couple complications with the head lifting, etc...However I have a thermal coated JH Racing 100% twin-scroll manifold and dump tubes along with the HX-52 if you are interested and a heat wrapped 4" side exhaust...

Why would anybody their tubular manifold? They ONLY hone cast iron manifold. They're high flowing manifold and honing tubular manifold is USELESS because it doesn't match the cylinder ports.

San Diego cops or California Highway Patrol, CHP, must be uneducated if you can get out of the 'under hood check'. Check out CVC 2806. They could make up any 'reasonable cause(s)'! And that code not only gives the cop a under the hood check but also gives the right for ref's to inspect your car...

Like I said before, California cops are prejudice. American cars can get away with anything albeit you don't drive stupid. I've never gotten pull over with my Jeep v8 5.9L race a non-full exhaust straight pipe race muffler, no cat, race intake manifold, cam, headers and throttle body. It sounds...

You can get away from anything if you have the cash and know the ins & outs of California and find the smog tech that will pass anybody. It's just about the cash that you have in your pocket. That the way economics works especially in California who's over $1 billion in debt. I've gotten away...

No worries, if you know your people in California you can pass smog and get your tickets sign off but I wouldn't necessarily be cruising around cause the cops in California are coming down hard in moving violations and could run up in the thousands of bucks.It's the way California having the...

Yes, it don't sound right. Imagine how it would sound you were to be boosting >20 psi. Look at what happen to you before! If Comp Turbo can't even get the basic journal bearing turbo design down would you really trust them in the design of the triple ball bearing design?

It work great for my friend's MR2 putting down 802 RWHP/ 848 lbs. of torque but I wouldn't call Comp Turbo very reliable. Comp Turbo was another company name, Innovative Turbo I believe, they abandon to save face.I would rather go on a 100 percent twin-scroll Borg Warner or Holset journal...

Holset HX52

That's what I thought but someone mentions the electronic solenoid are better than the Hallman spring/ball manual boost controller and will react faster.But I just wanted to make sure because I have been there and done that with the EBC and switching to MBC.

I know that one of the benefits of Turbosmart e-Boost is the 'adjustable gate pressure feature which minimizes wastegate creep AND' may or may not 'improve turbo response by up to 1000 rpm earlier in the rev range'.But will it help boost response my twin-scroll setup?With two...

I do more research, expecting 600-650 WHP out a DSM is tough job and WILL add up to a lot of money. There are better and cheaper turbo options than a precision 6268 billet.

I don't exactly remember what sizing turbo housing BigLady is running but he isn't running a twin-scroll setup and he is running 1.6L engine and Colorado high altitude.

I went with a divided T5 16 cm turbo housing and bored out the holes so it'd mount to the twin-scroll T4 manifold.JH Manifold is no longer business but with the 16 cm housing it will fit on that bottom mount manifold which makes life a lot easier fabricating the exhaust.As far as where I...

That's the way is it in California. There frown upon foreign cars. They'll let Camaro, Corvette, Mustangs, etc... get away with anything.Well, it was probably mention somewhere in the forum how much power and spool time you want but the like you said Holset are cheap and do the job...

I kind of lost interested. I grew out of that high school fast & the furious phase and when I came back to California there's no joke about what cops will do. If it's too modify they'll impound the car and crush it and with my HX52 and 4" side fender exhaust I doubt I could get away with that...

If what jusmx141 said is true about the s366 spooling 600-800 rpms slower than I'd have to say the HX52 spools faster or just as fast if you go with a twin-scroll HX52.It'll all pay off in the end with the HX52.

f|_|ck LS1 engines, I'll stick with my small and compact 2.0L 4 cylinder engine and I'll eat Honduhs and go hunting for V8s. :tease: :cry:

Why would you waste your money putting a LS1 in a DSM/Evo? A 2.0L 4 cylinder engine could easily take a LS1 and I wouldn't call the 8 cylinder LS1 exactly light weight.If you want 400 HP just go with a stock block with an hx35 or even a 16g.

It's 0.02 over and Eagle H-rod rods and Wiseco piston is good enough. As for the springs and retainers do not go the cheap way. Go for Ferrea, FP, Kiggly, HKS or Supertech. Kelford 272 require good shit.

As others have mentioned, as long as you have the proper support mods and you maintain it anything can be made into a DD.Hell, I could even daily drive my car around with an HX52 turbo beast but maintenance would be a bi***.

Damn, whoever wrapped that manifold did a $hittie job. It would most likely do more harm like crack the manifold then dissipate the heat. Keep it simple and thermal coat the manifold.

Oh well... what could one expect! All say no go.No new thing with Comp Turbo just like my friend was expecting a triple ball-bearing Comp Turbo to produce the most powerful mr2 at 700-800 WHP on a professionally stroked out mr2 engine. It just all went down in flames!

Any updates with this not just double ball-bearing but with this TRIPLE BALL-BEARING turbo?Indeed that is a pretty fast spool turbo but I guess that is the benefit of going to a triple ball-bearing turbo. Although the Holset HX52 is pretty fast spooling turbo too being able to do 27 psi @...

Amen to that, I picked up my freshly rebuilt HX52 for a mere $500. I will in no way waste $2500 on a turbo alone to put in my dirt cheap car. Spooling at 20~ psi by 4800 rpm and making 600 awhp at 27 psi on a 2.0 block is good enough for me.Once I resolve the head lifting I'll be even more...

E85 has higher octane rating than gasoline so it can be used in higher compression engine which tend to produce more power per unit of displacement than gasoline.

Yeah, oh course if you were stupid enough to match the amount of boost you're running to the same as a lower compression engine. Even though running higher compression you're set back by the amount of boost you can run it doesn't make the car less powerful.With my setup all clear and with...

If you're shooting for 600whp then you'd be running a lot turbo lb/min flow. I'd go slight lower compression like 8.3:1. I was restricted to 27 psi on 9:1 block with Holset HX52 because the head started lifting after though. Albeit it made 598whp but I was planning to run way more boost than...

Well this isn't much considering it's an 16 cm Holset HX52. Got a lot of work to do since the head is lifting at 28 psi or more and spraying coolant all over the dyno and need to come up with a better PVC and breather system because oil cap is spewing oil everywhere.And... someone who's very...

Ehh... don't think you're be safe at 10,000 rpm especially with Kelford 280s and going 9:1 is going to be difficult making high boost which I think you want to do because it seems like your main focus is torturing the turbo and making sufficient lb/min flow rate.Personally I'm not too fond of...

How's the turbo running?

If you say you've dyno 1000's of cars then you should be able to tell which ones are the best. You've got to have seen more brands of cam gear than I know of existed.

They are all the same, better than the stock ones. I'd have to say you've you'd have to ask whose tuner your car to say whether or not they'd prefer one over the other. Which cams are you running?

Oh yeah, I know there are way CA emission, $$$. Just wondering why you went with a full exhaust setup.

I'm pretty sure a couple of oz. in weight difference certain brand of adjustable cams wouldn't matter. There are a lot of other variable that would effect the power a car can produce it you're choose it on that basis and what do you mean by personal experiences?

You can buy a harness adapter.

Who are you talking to? I obviously don't DD my car around. And yes, a 3" dp and exhaust is good enough. It is very well capable of at least 600 HP.Does you car actually pass California smog with the 4" exhaust setup?

You're right on, the flow rate for a 16g is like 38 lb/min whereas a large frame turbo is more than double the flow rate like my Holset HX52 which is 89 lb/min. Thus going to a larger diameter exhaust will make a significant difference. Just imagine the performance difference when going from...

Has anyone tried mounting the oil pressure sender unit off the turbo oil feed line?

Well, that doesn't help. I'd like to do my work professionally. Anyone else with all the breakers, distribution block, cutoff, etc... wiring diagram?
