Meh, I'm wrong. Sorry for the bum input.

What size are the stock injectors anyways? 380-400ish?:confused: IDK I bet 525's would be okay for FI

The lowest I've seen is 600

600's are just over stock and are required when going FI or even higher.

If you went with a stroker kit you would need to go to 600's as well to adjust to the larger volume of displacement. as other have eloquently put it: More Air = More Fuel... stock injectors are in the 400-500 range.

As far as fuel pumps it is recommended to go to a 255lph or even DW300/330 for even better consistent flow to the injectors.

Also think of spark plugs too... More fuel needs more spark ;)

If the OP really wants to be confused look at the BMW twin turbo V8 they reversed the traditional setup of the intake and exhaust ports for a V setup. They have the exhaust on the inside where an intake manifold would be and the intake on the outside where exhaust manifolds and turbos would traditionally be. There are a few variants of this engine used now but the setup is the same. You'll find engines like this in and X5 X6 550 650 750 M5/M6

LOL... Bro I think you went "Simple Jack" on us.


Your username is Godzilla which in return is the nickname for the infamous "GTR Skyline". Yet you drive a 2000 Celica!?
Who goes to a Z forum who owns a 2K Celica? Unles you plan to own a Z in the future, it seems as though your just here trolling.
:shakes head:

I didn't know the new BMW powerplant was reverse flow.. Didn't think there were ANY production vehicles set up this way.

Pretty awesome setup, imo.

Ford's 6.7l diesel is also setup like this.

Yeah it's pretty sweet. It first debuted in the 2008 X6 then in the 750. And still used now just minor variations. There is the N63 and S63 engines ranging in power from 402hp 440tq like in first N63 motor I pictured before up to 550hp 500tq in the S63 variant in the M5/M6 pictured below. Then there is the N74 which is the twin turbo V12 found in the 760 and the Rolls Royce Ghost but that motor isn't reverse flow

Get off my ***, If you would look in the Introduction forum you'll find my post and story. Don't judge me unless you know more about me. :tiphat:

I knew this thread would go full Fabio eventually.


Tapatalk & such etc

The answer is 27.

Exhaust gas driven turbines (turbos) are spooled via exhaust gas, typically mounted closer to the exhaust manifold, and then forces compressed air into the intake manifold.

Belt driven turbines or compressors (superchargers) are typically mounted near the intake, and also force compressed air into the intake manifold.

Both typically have additional plumbing to a heat exchanger to cool the compressed air.

Both will increase air ingestion by the motor and therefore require more fuel in order to maintain combustion and power the engine. Additionally, some extra fuel may be needed to cool the charge and quench excess heat in the engine that can cause detonation and damage.

Is that what you mean???

With the question asked..as confusing as it is. I think the real question is what are your future goals/plans? What do you want out of a FI system?

You must be asking the forum for a reason other than the fact you want to know the difference between turbo A and turbo A.

But im sorry, The fact that you said your a walking book of car knowledge but then asked if forcing air into an engine changes its CR makes you sound completely ra-tarded.

This seems like it would be great from a servicing aspect. Think of how easy it would be to get at those turbos

You would think. It actually is still a big job. I have actually written up quite a few for replacement under warranty. The twin turbo v8 that's in the X5 750 and 550 has an aux water pump that is just for cooling the turbos. There was a recall on the aux water pump for not being efficient enough. Even with the recall for some cars the damage has already been done and the turbos suffer from bad seals bc of the added heat and the turbos leak oil. So the turbos position make it easy to notice and diagnose but replacing them still takes prob 5 hours working straight through. We are wondering if BMW will extend the warranty on the turbos beyond the cars manufactures warranty bc if not when these cars come out of warranty, that job would cost the customer just about $6500 I know it's over $5k just in parts alone to replace them
