SASSER

I am buying a GSLSE from a friend and the motor runs fine from what I seen. Would it be worth it keeping the 13BRE or put my extra S5 motor in it that I have laying around?

that is easy... do whatever you want to do...

Just kidding! if it aint broke then why fix it?

SASSER

its a free 25-30 hp gain pretty much besides the custom driveshaft, and I can fab that from what I am hearing, that's why I want to here from people who done it and like it or wish they haven't. Btw I plan on bport setup and nos and keeping it N/A.
Also would the 680cc injectors fit on the S5 without a fuss as well?

Sounds like you need to do some research before tackling something like an S5 swap.........

If your reffering to an N/A S5 engine,then forget the bridgeport plans since all N/A EFI engines are 6 port.Its tough enough to get a decent streetport on them,a bridgeport isnt compatible/possible, with the 6 port irons.

Youll only get the S5's factory 160HP if you retain all the S5 manifolds and running gear with the S5 engine,which means youd better study up on whats needed to mount the FC engine,deal with the electric OMP and wire the ECU......its not an afternoon job.
The low impedance SE injectors arent compatible with the 4 injector,high impedance S5 ECU.They would be too much fuel for an N/A anyways,the most youd need for a modified N/A might be stock 460's primary and some 550's in the secondary from a TII.Metered air EFI does a pretty good job of handling air/fuel delivery when mods are made,provided you stay within the metering abilities of the stock AFM.Dumping more fuel from the secondaries in isnt really required unless your boosted and exceeding 10-11psi.

If you really want nitrous,Id just stick with the stock 4 fuel injectors and run a wet system that will handle the nitrous and extra fuel all from common injectors,so its independent of the ECU.If you slap in bigger injectors and let the ECU run them,itll be pig rich anytime you rev it up, without the nitrous.

Running standalone, since bridgeport's wont run without a standalone decently I thought when i said bport you would expect that. E6X is in hand, was on the motor before I took it out and did a T2 swap with the car.

Thanks for the info about the gslse injectors I didn't know that.

Also there's a rican here with a race S5 n/a with a bport.

This is what I know of... *'s by the stuff mean I have it.

S5 longblock motor*
S5 trans (mint)*
S5 flywheel(mint)*
S5 clutch(2k miles)*
gslse flywheel(mint)*
gslse front cover*
gslse oilpan*
custom drive shaft (can fab)
E6X*
gslse car, runs but low comp and clutch is bad*
full S5 GTU if parts if needed*
Aero Fuel pump

Anything I am missing / need?

I am planning to premix.

Also, thanks for the post Steve.

what are you wanting to use the car for? id leave it with the stock motor, or a stock S5 na motor and DD it

Sorry,I didnt mean that S5's in general couldnt be bridgeported,just the N/A EFI 6 ports.

The TII irons are standard 4 port units and take to bridgeporting just like any rotary.You can run a TII block natuarally aspirated,or build an N/A engine with TII irons no problems.What I meant was if you have an N/A EFI 13B and plan on bridgeporting it without replacing any of the engine plates/parts,then your gonna hit some snags when you run out of material to grind.Most builders dont like to,or even offer streetporting, on the N/A EFI irons,they just dont do well.

If you end up building a 4 port bridged S5 engine,Id recommend switching to the TII manifolds on the intake.They are shorter and more condusive to breathing,especially on the topend.The convoluted N/A intakes are made to boos lowend torque and make up for the small size of the engine,they dont flow very well at the topend.Plus,the S5 N/A manifold has the VDI switching valve in it,which cant really be controlled/activated properly in all conditions,except by the stock S5 ECU.

Sounds like you have everything else needed to mount the engine up and handle the big stuff.Just be sure not to mix and match the stock flywheels between the SE and S5 engines.
