Rotrex 2ZZ BHP

[1979scotte]

parade rainer.... 

How much incl install though? Rotrex kit (based on se7en price) is £4.7k... and a turbo build is ~£3k? Maybe £4k for genuine Garrett + standalone ECU?

I'm just eyeing up the 90mm pulley getting you 220bhp-250bhp at the wheels..... WITHOUT lift working 

Definitely makes a Rotrex'd 1ZZ sound like a good idea!

Until you bring cost into the equation.
Genuine Garrett gt2860rs 800 quid.
Any rotrex C30 1700 quid.

I would think turbo build would be 4k with full standalone.
Seven kit only comes with power FC and for me that loads of money for ancient tech.

To be fair - they might be doing something different now, but that was the last time they bothered updating that page...

What would be the more modern equivalent to the Apexi FC Commander? I'm asking as many of these questions now, so I don't need to next year!!

Pretty sure they use g4 link now so I doubt the cost is the same. Their website hasn't been updated in years.

If they use a storm it will be 500 quid dearer if not more.
Monsoon would be good for 1zz.

Latest. Dyno wouldnt work, fixed late that day... Car had misfire at 6600. now waiting for new ignition coils to arrive on sat. get fitted, on dyno, fingers crossed!. Might make it to the show sunday....

[KRAMSNEHPETS]

early train to Rye yesterday, 6.15am.... Hung around for coils to arrive, 11.30, fit, down to dyno, 1 hour later, 324 bhp, 224 torque. Now feels like a 300 hp light car!. Home at 3.30pm, clean it, 6am start today to meets others for the ride to national show day. Great day out and good company.
Cost a small fortune to sort this issue out. Those tuning/dyno guys dont come cheap....

I'm guessing you are enjoying that!

[KRAMSNEHPETS]

So far so good!

Awesome news. Glad it worked out

Yeah, thanks: I'm getting prices coming in around £2500 for entry level (T28 knock-off, DET, but incl turbo timer...), but minimal rolling road time.
Around £4k for front mounted chargecooler, standalone ECU, proper GT25, possibly more if you want to really fine tune it on a RR.... like @KRAMSNEHPETS said, RR guys don't come cheap.

As ChrisGB told me, "turbo lives and dies by it's map." And given what we've been through in that regards... Please do yourself a favour and see the "fine tuning" as a requirement,not a perk. Whichever option you choose. Even if it's not straight away to split costs.

Have pretty much decided I agree with Pat.
Piggback is only temporary on your way to a proper ECU.
Full standalone may not increase your power but its going to be better in so many other ways.
I think I would take a chance on a cheap turbo put the money towards quality electronics.

Yep - I agree a RR run is a must, but if you have turbo components that are capable of 300wbhp+ (assuming a built engine) and you're only looking for ~210wbhp (stock gearbox + non-built engine), then I assume a budget of <£200 for ~2h on a RR should be sufficient to ensure a nice, clean power delivery...  then if more power is desired at a later date, I'll factor in a built engine, new clutch, etc... along with another 5h+ on the dyno...

Sorry - sidetracking from the 2ZZ / Rotrex side of this chat!!

engine knocking.........

Bottom end, or some knock? Not good either way.

[KRAMSNEHPETS]

Don't know yet, sounds like botttom. Will sort out trailer and transport to headcase. Gutted. Done 400 miles since I got it all sorted.

[wotugonado]

Wow! that's some sh1tty luck pal 

[KRAMSNEHPETS]

Sump off, end caps off, spun a shell... Ordering new shells tomorrow, wet and dry crank and put together. weekend may be up and running

[J03]

If the budget allows, I'd throw a set of performance ACL/King big end bearings in there & uprated ARP rod end bolts 

[KRAMSNEHPETS]

Just run engine up, still got the knock.... Engine will will have to come out and be stripped down. Give me suggestions what to do whilst out, Already has stage 2 cams. Talk to me about pistons, rods and bearings etc

[ChrisGB]

Uprated oil pump and oil cooler?

[KRAMSNEHPETS]

Am thnking along these liNES

ACL Race Main Bearings
ACL Race Big End Bearings
Track Group Forged Race Pistons
Track Group Billet EN-24(4340) H-Beam Connecting Rods
Track Group Xylan coated Oil Pump with uprated EN-24 Steel Gears
ARP Rod Bolts
Uprated Main bolts

[J03]

Personally I wouldn't bother with uprated conrods, the stock ones are more than adequate on your setup. Even with more power, the gearbox will sh*t itself looonnng before throwing a rod.

[1979scotte]

The rotrex is only good for 400 ish reliable horsepower.
On a 2zz it's never going to make enough torque to bend a rod.

Tbh mate if you've got the dosh for that lot bin the C series gearbox get an E153 and fit a big turbo.

Can't believe it's not stupid fast as it is tbh.

[shnazzle]

Yeah I'm not sure how you do it.
I can't even imagine how another 80hp feels over the turbo 1zz.
How fast do you want this thing to be? With 325 you must already be in serious supercar territory
