If I remember rightly, Roadrunner stuff quite old and rare now isn't it? The name rings a bell, I bet a few on here haven't heard of it.

Making your own kit shouldn't be too difficult, clock the turbo so the outlet is facing downwards, that section of pipe is pretty straight forward as it's right next to the core, then just copy the same route as any popular intercooler kit for the side that goes up to the throttle body. You can buy universal pipe kits for £70-80, then whatever you want to spend on a core.

Or you could just buy a normal kit, and modify the pipe between turbo and core.

I have a really loud squeeking noise

It's driving me nuts, what could this be?

Thanks

Your mrs? ;)

One of the best projects I've seen, a lot of time, effort and skill has gone into this, that shell was ready for the scrap yard most people wouldn't have even attempted to restore it!

Have one here but its the . boost gauge not PSI 15 posted

What make is it? Got any pics?

Not much of an update, have now got a universal pipe kit for my intercooler and a manual boost controller. The turbo is back from being rebuilt and will be ready to fit once I've made some adaptor plates, I've got some cardboard ones mocked up as a test already, so as soon as I get some bits of steel plate I'll get on with making them.

After the next week or so is out the way then I'll get on with fitting some of the parts with the turbo being the last thing to go on as I'll have to get a downpipe and exhaust system made up straight after as I've got nothing to use as a temp down pipe and don't fancy driving round with clouds of diesel smoke under the bonnet lol.

Once that's done then it'll be time for a remap! I'm told the injectors I've got are maxxed out at 185bhp so I'm hoping to get somewhere near 175-180 with this turbo.

Looking for a boost gauge, it must be accurate as I don't want to risk my freshly rebuilt turbo!

Preferably it needs to read in psi and go up to at least 25psi, don't care if it has vacuum or not, prefer if it doesn't.

Something like this for example:

I needed a turbo rebuilt and after getting some quotes from a few other companies I contacted Liam on here who gave me a much better quote than I'd got from anywhere else so went ahead with it.

My turbo needed a general rebuild (bearings and seals) as well as a new compressor wheel, which I supplied myself as it worked out slightly cheaper.

However somewhere along the lines there was a mistake and I had been sent the wrong part, initially Liam was going to modify the compressor housing to make it fit, but it turned out he couldn't, so supplied me with a new compressor wheel - problem solved and no extra cost!

The whole time there was constant communication through texts and PM's so I always knew what was happening.

Couldn't have asked for a better service and will always return to him if I ever need any turbo work doing in the future.

And to top it off there was free next day collection and delivery!

I will get some pics up when I get chance, it looks like a brand new item compared to how dirty it was when I sent it off!

I didnt think i had mis-read anything but welcome to explain what you mean.

im perfectly calm from your post you seemed to think there was contradictory information, as i didnt see any wondered if you needed help understanding anything thats all.

Regarding the quoting of your posts, i thought it right to address your the questions you asked and are are now complaining about having received answers for.

I apologise genuinely that this seems to have upset you somewhat.

Phil

Are you for real?

"wondered if you needed help understanding anything" are you actually serious? Do not patronise me lol...

I haven't asked any "questions", my posts in reply to the other guy were rhetorical.

And after that I just skim read the replies and saw various things posted that contradicted eachother, from no one in particular.

I'm not sure why I'm even wasting my time, my earlier post was trying to be helpful and clear up confusion, this is why I rarely post on this forum anymore.

What the actual fuck are you going on about mate? You need to calm down and stop miss-reading things, I've said nothing against you (or anyone really, just expressed opinions) so why quote all of my posts?

So much contradiction here, one guy saying external wastegates are rubbish, another one saying there are turbos designed to work with external gates...

Regardless of what is "better" it stands that the vast majority of cars use a wastegate on the exhaust side to control boost, it doesn't matter what technical stuff you post on here, my original post explaining the difference between BOV and wastegate applies to 99% if not 100% of users on this forum and anything else after that just adds to the confusion.

I just said that the BOV's are modified with stiffer springs, and are generally used in conjunction with a solenoid valve.

Besides the only reason you use an external wastegate is because the turbo is poorly designed.

An external wastegate is generally an upgrade over the internal one.

Are you now suggesting that almost all turbos are poorly designed?

Are you seriously suggesting that having a massive boost leak is a better way of controlling boost than a proper external wastegate?

Technically they are the same and you can use a BOV as a means of controlling boost pressure, look back a few years to the frenzy turbo era of rally engines and you will find they used a BOV to control boost pressure on the compressor side of the turbo.

Sounds like a poor way of controlling boost to me, letting the turbo spin much faster than it would if it was controlled by a wastegate, would surely put the turbo out of it's efficiency range and then keeping the BOV open to release air you've essentially just got a massive boost leak...

Technically they may be the "same" as they are just valves that allow air through them but in that sense you are just going to confuse people.

An inconclusive TD04 it is then just need to find a decent second hand kit then(anyone)

What will be needed to make sure the mines ecu is running the setup properly ?

You'll need to keep an eye on air/fuel ratio, but keep in mind that a TD04 at 1 bar will be flowing more air than a CT9 at 1 bar.

what about if you run an external wastegate ?? And if you don't have one could you use a bov instead or will I need a wastegate ??

BOV and wastegate are not related, the BOV is on the inlet side, wastegate is exhaust side.

A wastegate (whether it is internal or external doesn't matter) is what controls your boost, it opens to let excess exhaust gases bypass the turbine wheel once you have reached full boost (this will either be down to your boost controller, or the wastegate spring itself if you don't have a boost controller).

A blow off valve releases pressure from the inlet side, when you lift off the throttle the turbo will still be spinning but because the throttle is shut the air can't go into the engine, the only way it can go is back the way it came - through the turbo. It isn't good for the turbo, so the blow off valve releases the excess air.

MeisterR are the best option in my opinion, they are perfect for road use, and the customer service is very good. Plus if you do need to replace anything it's easy, whereas if you need to replace parts on JDM ones you are fucked.

Dont like these myself.prefer chatter anywho

Nice avatar lol

Keep the engine and stick a turbo and a Bosch VE pump on it.

The do go well when tuned a bit. I fitted a bigger turbo and injectors to my mates mg zr deisel. Think it's around the 190bhp mark now. Smokes like a trooper haha

Is your mate's name Owen?

Cheers for the comments lads

@ Addymk2 - anything you want to know about these cars, PM me! You can get them to 130+ bhp easily and cheaply and up to 150 on the standard turbo if you're willing to pay for a remap. Definitely pokey enough for a daily driver that will still get 50mpg and out handle most cars on the road even on standard suspension, not to mention the leather seats or the practicality of 4 doors and a big boot. Oh and I only paid £1.5k for mine!

..........

+1 for Liam, very helpful

Valve stem seals?

A TD05 is bigger than a TD04, it will spool later but is capable of more power.

Whether you need or want a TD05 is up to you and depends on your power goals, I've been out of the Starlet scene for a while so can't remember exact figures but basically if you're only aiming for just over 200bhp then a TD04 is fine, however if you're aiming for big power then stick with the TD05.
