Title: Michael's turbo build
Post by: michaelb on July 2, 2018, 14:12
Following inspiration from Dan, I'm undertaking a turbo build of my own! I've just purchased a new manifold from Turbokits.com and now I'm trying to decide what turbo to go for. Dan has put the GT2554R in, which seems to be delivering great results but I'm still wondering about the 28 instead. I'm going to install a link standalone ecu and injectors from an Astra VXR. Any hints/tips would be most welcome!

Tips: speak to Dan :)

There's not a hell of a lot he hasn't covered, considerered, discussed, etc.

As for turbo; get the right one for what you want.
Lag, kick, top end, low end torque/flow, etc.

Cooling cooling cooling. Get a charge cooler. Don't consider intercooler. I don't care how fancy a setup you've designed or how big the intercooler is. Just get a charge cooler.
Oil cooler. Vents. Fans. Shields. Do everythinf you can and must to keep intake, exhaust, oil and water temperatures down.

Nice choice on the Link. Can't go wrong. The EMUBlack mapped by RRR is a winner if you want to save pennies but the Link is definitely a class above.

Cooling.

Definitely go charge cooler. If you do it from the start the cost probably won't be that much different.

Other than that it's pretty flexible.

I love my turbo. But if you want more kick. Go 28. I've been in a car with the 28 and it's a huge burst of power but a fair bit of lag.

The only 28 to go for is the gt2860rs even then Dan's gt2554r with a charge cooler would probably push 260 or more at the crank and I wouldn't want to push a stock 1zz too much harder. Then there is the torque limit on the gearbox to consider.

Charge cooler it is then! Yeah I don't fancy having to upgrade the gearbox too!
Title: Re: Michael's turbo build
Post by: michaelb on July 2, 2018, 18:25
Is there a particular charge cooler that works?

Biggest eBay chargecooler you can get.
Proper Bosch pump.
Quality charge cooler rad again biggest that will fit.
Or if you have budget constraints try the fiat Cinquecento rad.
Title: Re: Michael's turbo build
Post by: michaelb on July 2, 2018, 21:16
How do you know which will fit? Just a guesstimate?
Title: Re: Michael's turbo build
Post by: dan944 on July 2, 2018, 21:21
Decide your intake pipe diameter. Probably 2.5" (63mm) then search for coolers with this diameter Inlet. In all fairness. I found there's LOADS of room so just get one and make it fit lol. Use the dimensions to check. You could even mock it up with a cereal box or something.

Post by: michaelb on July 2, 2018, 21:31
The barrel one looks good and probably fits better but the stats seem to suggest it isn't actually very good! I'll have a hunt on eBay. Did you put a charge cooler in Dan? I thought you had an intercooler?

According to research (Lee) the eBay ones are better. I haven't researched it properly though.

(Sheepishly) I have and IC. Probably should have started with a charge cooler though. I think it's in the pipeline.

I take it I need one which goes in one side and out the other? Not one of the ones where the air pipe comes out on the same side?

I think the pipework would start to get more complicated with the pipe going in and out the same side.. maybe.. I'd need to look a bit closer at it

I haven't done it so I'm not the best person to speak to but have a google and look at the images it comes up with. Design your own. Let the garage decide. It's completely up to.

I'd say intake pipework is probably the biggest variable between set ups.

When it comes to the chargecooler rad, the Ford Focus RS Mk1 CC rad fits nicely behind the front bumper as long as you don't have AC

Was looking at this charge cooler, anyone know anything about it?

Has anyone got any info on the longevity of the 1zz with a turbo installed? I was just chatting to a race tuning company and they were concerned about going beyond 250bhp with the old 1.8 vvti engine
Title: Re: Michael's turbo build
Post by: shnazzle on July 3, 2018, 19:18
Depends how you drive it.
People on here have had their turbos for years and many miles (Ardent, s12vea, etc). If you service it well and drive it with some degree of sympathy there's no reason why it won't do 100k miles.
Keep that oil fresh and your map good and you'll have a happy engine.
Watch for any signs of wear and address asap.

The race guys told me it would be around 2k to purchase, install and map a G4 Link Storm. Does this sound a bit steep? He said the Storm is the cheapest Link ecu that will provide the capabilities for the vvti drive by wire that I need. I looked at the EMU Black and it seems to do the job just as well but it's only about 850 to purchase.

2k sounds about right.
How come you have DBW? Is it an SMT?
That opens up a lot of cool functionaliry in the EMUBlack.
I don't know much about the Link Storm. I did research it a bit and it definitely does the job for our car. Easily.
But so does the Black.

Personal choice really. EMU is quite new on the market (but catching up quickly) and the Link has proven its worth.
I'm very happy Mike started the group buy. Amazing piece of kit.

No my car is a manual but the guy thought the mr2 has an electronic throttle? I didn't know as I've never had to find out lol. Does it not? I like the EMU Black, it does look decent

A quick look at the specs;

Link has 2 more outputs each for injectors, ignition and auxiliary. Black has 6. Do you really need more?
You only need 4 for the mr2 and 6 aux outputs pretty much allows you connect anything I can think of.

Storm has 3 temperature outputs. Black has 2 just for EGT and however any inputs you have left for IAT, oil, etc.

Black has built in traction control. Link does not.

The more I look at it... The Black is a very clear winner haha

Well that's that sorted, EMU Black it is! Now just the charge cooler, radiator, pump, clutch, sump and turbo to decide [emoji23][emoji23]

2k for a link storm is spot on. It's 1200 quid plus A and B looms plus sensors mapping and fitting. In fact it will be more than 2k. This is why we really wanted this ECU master group buy.

250bhp is fine on a 1zz bhp doesn't break engines it's torque keep below 250 ftlb and I wouldn't go over 10psi on a gt25 type turbo.

After all my recent experiences I would honestly find the money for a rebuild whilst doing that fit forged rods. Obviously it's not cheap. Reliability is paramount. Can have 1000bhp but it's no fun when the car spends half its life off the road.

That has been my issue Scott, I keep harping back to putting a 2zz in with modifications as I feel it would deliver better reliability.

A straight engine swap is probably best for reliability but you have to be careful some 2zz swaps do feel down on power and my V6 is nothing but trouble.

Also if your looking for a big power hit stock 2zz ain't gonna cut it even if it is massively quick on b roads or tight tracks.

Try the different options if possible and weigh the costs.

I'm looking at a 2zz swap now with se7en cams and baffled sump. I may also still install an EMU Black.

I may consider the supercharger after the swap

Ok, I had a good chat with Lee in Se7en and he has convinced me that a 2zz swap is the way forward, especially if I'm considering adding big hp at a later date. I'm going to install a new diff, cams and sump along with stage 2 clutch and EMU Black ecu. At a later date I'm going to go for a supercharger. So I just bought a brand new turbo manifold for a turbo from turbo kits.com so I'll put it up for sale!

At the very least, the 2zz will be a considerably better engine than the 1zz. I'm happy with my decision, it's taken me a while to make and a turbo manifold lol
