Hello, I currently have a B16 in a metro and need some advice on which turbo manifold and turbo setup would be best, am looking for no more than 350bhp and the car is primarily for track use although it is road legal. The problem I have is because space is very tight the alternator is located at the front of the engine although I have no power steering or AC to worry about.

Bearing all this in mind what would you guys recommend, I've been looking at a few log manifolds and the quick4 spoolin manifold but which is the most compact bearing in mind the turbo wont need to be massive. Thanks.

 

I went with the spoolin performance log. Thats about as compact as it gets and is a good manifold for a goal of 350.

 

Cheers bud, what turbo did you go for? I need good drive out of corners i.e. little lag

 

I went with a GT3076R cause it gives me room to grow. You may want something like a BB 50 trim with a .48 or .63 AR if instant spool is what you are after.

 

Quick question, do most of the spoolin performance manifolds log/quick4 place the compressor on the left of the engine bay looking from the front (i.e. on the passenger side in the US)? Can you flip the turbos round so the compressor sits on the right or will it push the turbo a lot further forward?

 

I'd look at something that wouldn't require any grinding of the block (especially if using a spoolin' manifold). you can still stay journal bearing without the need of a ball-bearing cartridge. Look to your budget and type. Are you circuit racing?

 

Only the Quick 4A/C does that. That standard Quick 4 has the compressor housing on the US Driver side. IF you're circuit racing journal bearing is nice, but water cooling would be HIGHLY recommended. So whatever you choose, USE WATER.

 

Thanks, I think I will go for a T3/04E 50 trim I'm assuming these are water cooled and shouldn't need the block to be altered? Yes it's going to be used for track days so don't want something too laggy but it's not being raced just a fun toy

 

No. the 50 trim from the sources do NOT come water cooled. THey are standard oil cooled only, unless it is a ball-bearing cartridge.

As for the block being "altered", could you please elaborate as to what you're referring to?

 

Sorry I meant grinding the block to allow clearance, or is this only needed on v large turbos?

 

its mostly needed on larger turbos but depending on the manifold you would have to grind the first block rib by the block identification stamp..

Which way do you want to orient the turbo? Some manifolds are passenger side placement only and turn the the turbo as to facilitate clearing a/c components.. others can go either way but the popular choice is to face it towards the us drivers side (assuming your manifold choice supports this) it makes downpipe fabrication much easier and shortens and simplifies charge pipe fabrication. If faced towards the drivers side no block notching is required. Running the turbo this way also sticks the turbo out further towards the front of the vehicle, as we dont have any photos or measurements of your particular application I cannot say if drivers side placement will work for you

 

Thanks for the info much appreciated I don't have AC or PS but the setup needs to be as compact as possible, trying to upload a pic but keeps failing... I have a big rad in there at the moment but going to fit an alloy civic rad soon which will free up some space, I was thinking the air filter etc would get in the way if the compressor was mounted on the passenger side although I'll get some pics and see what you guys think

 

 

As you can see space is tight! The rad at the moment is mounted where the 'caution' sticker is on the slam panel so when this comes out I will have a bit more room, intercooler could be tricky though lol.

 

can you measure from say the face of the exhaust flange to whatever is closest to the front of the motor?
I can help you better if you can do that

 

From memory it was 17cm with the rad currently in, but with it out it's about 26cm. I'll check one night this week though

 

thats really close. Thats from exhaust ports to radiator?
This is how my T04S housing sits on my current manifold

and a T04E cover isnt much smaller, its less than an inch difference IIRC (I measured both but didnt take pics of the E cover)
Inside the housing sits about 1.25" off the motor, the outlet when clocked down is damn near touching the motor. Center of the inlet is 5" and the front of the housing is roughly 8.25" from the motor.


Heres what the manifold looks like

As you can see, its one of the smallest manifolds in terms of how close it places the turbo to the motor. To get any closer you'd need a true log manifold or custom build one.

you can make 350 pretty easy with a log and get faster spool but you'll ultimately have very high backpressure pre-turbo, which lowers exhaust flow, efficiency, fuel milage and raises egt's... and ultimately lower power (to a point in relation to say a top mount or ramhorn) I know a guy that ran a log then swapped to a top mount and picked up over 50hp and the same boost level

 

heres a b series log manifold for sale in the classifieds. it favors passenger side compressor placement

i hear a turbo from a volvo v70 t5 has little lag. i own one but never try it.

 

Thanks for the pics!!! Have been looking for a pic like that for weeks! What manifold is that?

 

um what?
we arent talking about turbo choice here... but manifold options for proper turbo fitment

A volvo v70 has a TD04HL-13t-6 turbo... thats a 390CFM turbo at its absolute limit at the choke line at roughly 14.7psi...

 

Its a revhard tubular "min-ram" of sorts... and its for sale lol
Youd need something like mine or a straight log for clearance.. Im almost positive you have more room than what you think at the moment... less than 7 inches sounds overly tight. If you can run a civic half core in the place its supposed to be if you had a civic, you shouldnt have any issues

 

Just a quicky, what is the closest turbo to a T3/04E 50 trim that is water cooled? Is there any advantage to buying a turbo with a 5 bolt turbine housing as apposed to 4 bolt?

 

That would be a GT3251B journal bearing. Those are water cooled and similar in response to the 50 trim (actually better than the 50 trim) The advantage of 4 bolt is easier to fit and remove. the 5 bolt is more difficult.

 

What about a inline pro turbo manifold?
