I want to buy some 880cc injectors, brand is PTE, advertised for evo 8 and 9, will they work on evo 5?

PTE 880cc injectors... Yup, they'll work... but... with stock cams and Evo 9 turbo??? The problem is that they will give you a less finely atomized spray pattern and more flow than stock 560 cc injectors.
That may cause even worse issues elsewhere. Even worse milage... or issues at off-idle "tip-in", etc.

IMHO injectors should always be matched to the other parts used (cams/turbo/exhaust etc.) for a particular combination. eg. Forced Performance recommends 690 cc injectors (minimum) with their EvoGREEN turbo. That's exactly what 9sec9 (evom.net) used for OKIX's car... and that one made over 500 WHP eventually.

The watchwords here should always be "Tried & Tested"... Always try to use parts combinations that have repeatedly be proven to work. In this case it's better to let others experiment. Cheaper too. Then you won't waste $$$ on mismatched parts. People like Buschur Racing, AMS and 9sec9 (etc.) are much better guides than "hit or miss" 2nrs who select their parts combinations by following "fads". So read their project reviews and dyno sheets on evolutionm.net / MLR etc. If it works for them... it'll work for you too.

Didn't see that you replied here Sanct.

I got those PTE 880's after all. Recommended by many on EvoM even trusted Vendors like Buschur who sells them. I asked multiple tuners on the board what should suffice and leave room for a certain level of modification. They recommended 880cc - 1000cc and said the tuning could get them to idle like normal.

Will not be using stock cams, GSC S1's are the cams of choice. Fat powerband with no low end loss. Will be competitive in drag and still fun on the road. I'm not looking for a drag beast, else I would do springs/retainers/Kelford 272's maybe, and an FP Red with the new housing. I'd like to remain very streetable so I'm looking at the new ARMS Tomei turbo to suit my needs. They place it somewhere between a Green and a Red although not many have posted any graphs about it on EvoM.

A tuner told me he has gotten great results and multiple 400whp+ cars with the new Tomei. There are a lot of complaints about the FP turbo's on MLR being unreliable, US Evo's have great success with the Red though. I guess it boils down to what you choose and hope at the end of the day it puts a smile on your face. Mr. Green Mitsubishi

FP turbo's on MLR being unreliable... Nope, only when the Brits run EvoGREEN at excessive boost levels.
above 1.8 bar (26 psi) i.e. 1.9-2.1 bar (27-30 psi) on pump gas.
I haven't read of any failures with EvoRED so far. If you have, post the 'urls' please.

multiple 400whp+ cars... CAUTION: All data so far shows 400+ BHP... not WHP.
So far, it seems that the Tomei ARMS has quicker spool... but LESS power and torque than EvoGREEN.

Looking forward to your review of the Tomei ARMS turbo, if you decide go that way...
Too little feedback on this one so far.

Those are some threads about the FP turbos.

I'm not saying the turbos are faulty, keeping in mind external factors such as oil pressure, boost leak, which could cause a turbo to overheat, or overspin, and sustain damage.

I agree that there is not enough on the ARMS. We'll never know though unless someone tries and is willing to share the results.

On another note, I was reading on the MLR that the stock piston tolerances are circa 500-550 bhp, and they achieve this via swapping to forged rods, without any breakage. Are the E4-6 pistons the same as E7-9 in terms of tolerances and what they can handle?

So let's say I was to go down the FP Road:

FP Red
Ported Mani
EPM O2 Dump or Megan O2
Forged Rods
ARP Rod Bolts
E9 Head gasket
ARP Head Bolts
Ported Intake Mani w/65mm throttle body
880cc Injectors
GSC S1 268 in / 268 ex Cams
Hard-Wired Walbro 255lph HP pump
Uprated intercooler w/piping

W/ Full tune @ 25psi on pump.

What's your opinion on that setup?

sounds like 400whp.

im currently pushing the stock 9 to see what it can do. On straight pump I get inconsistent results with any boost above 24psi. however on a hail mary tank, I ran 27psi without knock before.

Im currently playing with methanol injection and higher boost, but my results so far are cursory.

Stock 9 is also an option for me due to the gross difference in price Laughing

I was also thinking about Meth injection due to the crappy gas that we get here in Grenada as well. Very inconsistent. After I changed to the Walbro, KnockSum went down but it would vary day to day due to the shitty gas.

What's the details of your set-up and what model Evo do you drive?

Thanks for your input btw. Cheers.

I drive the black evo 6 in the other thread u are posting in.

If u are planning on making 400whp, a stock 9 will not do. I get 350whp reliably on pump. Even with meth so far the most ive seen is 390 @ 28psi. The meth does help with the inconsistent knock, but when u start to push on the meth, u run into the same problems u do while trying to push on straight pump.... it call comes down to the inconsistency of the fuel.

Have you been to a dragstrip with your car? How does it run?

If not can you make an estimation maybe?

Is your 6 a GSR? Does it still have an AYC Diff?

A guy here in Grenada with a 5 GSR imported a non-AYC Diff from a US Evo and swapped it in, retaining the 5 GSR front diff. I think the ratios are slightly off but he said that it's negligible.

i have the ayc disconnected. im not going to spend money behind it anymore.

i have no idea what it runs in the 1/4. a 1/4 mile wasnt my objective.
