2ZZ Compressor fitting help

[mikek]

How do I figure this out though? Currently running a BCM CDA intake and Rouge manifold/sports cat and your silencer.

K20 would be great but just to expensive ATM.

Is the Rogue manifold the Celica 2zz one cut and tweaked slightly retaining the single port flange ?  i think these are best for these cars so if so your good there, the swap manifolds that go into dual port flange like stock 1zz are not good for power from what ive seen, silencer wise plenty of flow for 250hp there    sports cat could be holding you back depending on quality and age, maybe get a decat to make sure flow is maximum.

Intake wise it can be more tricky with stock ecu but if going aftermarket then good cold air feed with sensible size pipework and should be good, not sure what your BCM intake is.

Your never going to get big gains without forced induction, also what about doing the ECU and getting current setup at its best and then saving for a Rotrex setup ? if you already have the ecu that is a big part of cost one you go to next step but still not cheap,  it will probably work out cheaper than a K20 (done properly at least) only possible issue is Toyota gearbox strength but with Rotrex making linear power and no big torque spike like a turbo it should be easier on transmission.

Also maybe a dyno run as it is now see what its running?, it maybe you are already making decent power for a 2zz as it seems to vary a lot on these swaps, if your say 180 ish then your doing well but if not the ECU with good mapping could unlock a few more ponies, speak to Pistol Pete see how he is going with his setup now its on Ecumaster.

Mine with stage 2 cams was being held back by air intake, which is the same as yours, this will be the limiting factor with your current set up. When we removed the intake at RRR it made over another 10 WHP.

You still running the BCM CDA intake or have you found a more free flowing option?

Still running it but I have the bits to change it, cone filter and bigger pipe going behind the battery at some point, expensive though because it will then need a re map!

Will have a look at doing the same,already got the maf pipe, will just need a filter.

Current setup below. I can use the MAF pipe to go behind the battery and just fit a filter. I'll just need a straight silicone coupler to the TB.

As you can see there's a lot of pipework, which goes all the way to the NS side scoop.

With stock ecu always best to keep induction as close to standard as possible otherwise as with the 1ZZ you loose rather than gain.
Remember @mikek has a fully re mappable ecumaster black.

So keep as is, or find a 2zz airbox?

@rusty0273 would you be able to confirm the ECU part number your compressor is running?

Below taken from your thread: https://www.mr2roc.org/forum/index.php?topic=70018.msg834311#msg834311

Uses two ECUs - one from the original 1ZZ and one from a 2ZZ but I don't the details of which does what. Will take a few pics later and post up this evening or tomorrow. If you have a specific queries on it I'll try to answer.

Afraid I don't have any details that will necessarily help you and looks like you've resolved the query on ECU. I bought my car already done by Rogue. The guys at Rogue seem pretty helpful. Patrick Mortell is on the MR2 2ZZ Projects group on FB and would have been the guy who did the wiring conversion at Rogue. He can probably advise if you still need it. I appreciate they are not in your top ten list of trusted garages!
I would agree  with the other comments on the effect of the compressor - very much beneficial to general road driving with plenty of lower down torque. Doesn't feel like it lifts the top end power by much for track work.

Cheers mate. Yeah gone off the idea as my engine is constantly in the higher rev range on track so wouldn't really benefit with a compressor setup, might purchase the kit if at a decent price and punt on on eBay.

If its like the 1zz it seems to work best with a stock intake.
Everyone thinks these big air filters improve on toyotas engineering. They don't without changes to the ecu.

Lotus intake offering below, seems if I fit a straight coupler to the TB and run the BCM intake behind the battery its a similar concept.

I still think you need to dyno it and see where your at before making any changes, it could be all is well and no real gains to be made without big changes

Gonna get booked in at EFI in Runcorn for a session.

I would look up the blue bomber modification.

 Later it was found out that the  WRX uses a similar MAF and an aftermarket company made a calibrated MAF tube which plays well with the ECU. The tube with the vanes measures the same as the OEM 2ZZ MAF housing and I felt It made a big difference particularly at part throttle. It has all of the benefits of the OEM and aftermarket intake.
