jsnow82, what manifold are you using?

I believe he is still trying to decide on that one. I know he wants a divided one though.

yea, i have yet to decide on one yet or i just may design on my own. i should be ordering my turbo tomorrow tho, so thats my first step! they are very expensive, almost as much as the turbo!

hey, got that block out yet to get pinned? :)

idk.......a goal of 500rwhp on a series 4 block (well, series 5 front and rear plates) unpinned......that's kinda sketchy in my opinion. But that's just me :icon_tup:

pics of his S372 from yesterday. It has the race cover and a .90 divided turbine housing.

(since he never posts, I'll speak for him :lol: )
He is still trying to figure out what divided manifold to use because he wants to make sure that the turbo will clear the lower intake mani. Because of the fact of how much the turbo alone set him back money-wise, 1 of his options he is considering so far is to buy the HKS divided cast manifold made for the 3rd gen. IDK, maybe he'll consider a tubular mani if it's the only thing that will really work for this setup, just as long as it doesn't break the bank, aka: $650+

Borg Warner turbo's really don't cost a lot. My Garrett 42r set me back 3 grand! I hate when people try to minimize costs when it comes to cars. If you don't have the wallet or the mental power to save money for a month then building a car isn't for you.

Anyway, the cast manifold is a really short runner manifold and will likely put the turbine housing into the passenger strut tower. I had a tubular manifold on my last BW turbo and it still hit the passenger strut tower. You're going to have to spend money on a manifold that's GOING TO FIT. Being cheap cost's more in the long run and rushing things takes more time. Research with some known vendors to get a manifold that will fit your setup and then pay for their properly priced manifold because they spent time to develop it to fit.

Not sure what chassis you're working with but the FD HKS manifold will not work. I've test fitted a 374 w/ race cover and the turbo fits great with the engine on the stand. But once it's in the car the turbine and compressor housings hit the body in a big way.

lol I dont mind spending the money for something that WILL work! I would just hate to spend $1000 knowing the $400 will work. FUNCTION over LOOKS for me! I know I may be spending the $1000 anyways and still have to get an exhaust made, another $1000 or more for a 4 or 5inch custom exhaust. On another note, THIS turbo is huge, its a very nice turbo and should hopefully put me where i want to be. Thanks Brian for posting up the pictures. I have a 2nd gen chassis with the s4 block.

Any suggestions on a manifold that will fit?

Thanks for everyones opinions, and mono4lamar I completely agree with you, I have just already spent alot of money this year with buying a turbo, setup and not being completely happy and then rebuilding halfway this year again because of boost spike! Its been a rough but very fun road so far.

I know I come off as a negative Nancy sometimes it's just sometimes you have repeated questions. LMK if you want me to weld up the 4" turbo back (where in PA are you). I'll upload pictures of my setup if you want. Anyway, spend the good money and you'll likely never run into problems. Just do the research don't let too many people point to the direction... It's your car!

Repetition is a way of getting to the point sometimes man, ppl seem to forget the point of ? after only a few replies. I do alot of research, read a lot and ask a lot. Im thinking of a 5inch exhaust for spool, what do you think? Will 4inches do the job? I found stainless steel 5 inch piping. Mono4lamar, if you dont mind, upload the pics, i want to see your setup. thank you

From what I gather you're not going to be drag racing it and you'll be street driving it. 4" will be plenty for you. I'm running the 4" turbo back on my 42r setup and I'm very happy with it. I'll get pictures as soon as I get a car off my lift.

I found a couple pictures of my down-pipe on my other laptop. They're just pictures of it tacked up but you get the idea... Oh and ignore the custom upper intake manifold in the background ;)

looks very nice man. how much will you charge for the complete turbo back? I think I may be doing the 4inch stainless.

Pricing would depend on the midpipe muffler (if you want one) and the muffler at the end. I would still need to see the underside of the car to see how many bends are involved. I have an idea in mind but we need to discuss it further. Shoot me a pm when you're ready :)

Just because you spent 3K on a GT42 does not mean it's a better turbo than a $1000 unit. Some of the fastest cars are the guys that spend their money wisely. Couple that with a little experience and some technical knowledge and that handy miser will go much faster than the ones that spend the top dollar. In a number of tests done the Borg Warner/Bullseye journal bearing turbos out-perform the Garrett dual ball bearings units which are twice the price. A lot of guys that jumped on the GT42R bandwagon are definitely now regretting it.

Anthony

just read the thread and want to give kudos to post 11.

Dudemaaanownsanrx7 has written on of the best posts on the board about making the difficult choice between items that aren't mutually inclusive.

and yes, you can pick something in the middle but you can't have tall and short.

Very skeptical on what bullseye promotes as far as numbers, I have seen first hand that side by side what they claim a lot of times simply isn't the full story and disingenuos at best. I am not knocking BW turbos in any way, nor am I endorsing garrett.

The single biggest benefit to a BW turbo to the average guy is two things, cost is less when buying off shelf stuff, and you have a nice selection of wheel combinations for the average guy to choose from. Whereas for the consumer, garrett pretty much gives you their idea of best ie 42R for garret 82mm turbine wheel and BW S400 you can select 83,87,96mm turbine wheel.

For the consumer that is fine, in my position (and other members on here I'm sure) it makes no difference, I can get wheel combos I want for garrett as well in most cases. Most of the time though it isn't needed as the wheels are paired nicely.

What I don't like about BW, if I have to have any complaint, is that you're stuck with the overweight one piece backplate/CHRA.


~S~

Agreed, I deal with it everyday.

I would say only that this point here.....

Can have a smaller A/r and run a larger exducer bore and still get a bit of both. The idea is to spray the "pinwheel" with air and have it exit as swiftly as possible, too large a A/r and air doesn't hit the "pinwheel" directly and exit so quickly, you lose out and only create lazy response.

I would prefer a .X A/r with 79mm exducer bore over the same .X A/r with a 74mm exducer bore, before stepping up the A/r on the 74mm wheel. I've seen it keep response and gain power, where as stepping up gained power but lost some response.

Truth is this is all way too much thought for a car to just drive around in on the street. 450+whp FD on the street is a blast, and most wont notice differences of a few hundred RPM from one turbo to the next, because most cars are set up so different form each other you can't compare the turbos themselves fairly.

~S~

I think Garrett is by far the best units made still. I also agree, the two peice design is much better then a 1 piece design from BW. The S400's do have quite a few turbines to choose from. The 90mm turbine wheel also is a KILLER piece on the rotary for the money and I didn't see it mentioned. The 96mm turbine is a little to laggy for my taste and that 90 fills in the gap quite nicely. Also Bullseye is a marketing hype. They claim overrated #'s for their turbos and most of those units are direct from Borg Warner, and Borg Warner doesn't even rate them that high :lol: . To many of them have blown up on the dyno with very few passes as well, so Borg Warner due to Bullseye's marketing has lost some fans. Best thing to do is buy box units from a diesel shop. They are all available to the public as off the shelf units anyway without all the price jacking...all you need is the part #. If you need a BW part # let me know, I got my hands on a full spreadsheet with all the BW's..or at least most. The prices are ALOT cheaper when buying from a diesel shop.

I would personally love to see a GT45R-74mm unit. 87mm turbine with DBB the tried and true GT42 comp wheel. Would make for a heck of a turbo.

Anthony, you're preaching to the choir here. I was just using the dollar for an example for how costly this "game" is. If you were up to date on my situation you would know that my 42r from Garrett is BLOWN! My last turbo was a s362 and I loved every minute of it. I should have gone with the Borg Warner s374 but I wanted something water cooled. I'll never purchase another Garrett turbo in my life.

Ill let you guys know how the turbo runs when i get it on the car and tuned.......you cant judge a turbo from one or two mishaps, Borg Warner makes OE turbos that perform as well as last, now they're in the sport compact market being marketed by Bullseye. We will see what it can do, but only time will tell. Thank you guys so much!!!

As far as midpipe and mufflers, what do you guys suggest for sound quality and reliability. I have always been a fan of the racing beat sound but I know that I will probably not be able to get that sound again.

If you're doing a 4" exhaust you don't have a lot of choices. I'm running a Borla XR1 as my muffler (pretty expensive) and a Dynomax Ultra Flow muffler in the midpipe. I really love the sound it makes. I'll try to post up a video so you can get an idea...

cool man, thank you. will one muffler be alright? or will it just be too loud?
