All setup and ready to go, all am waiting for now is the oil connector for oil feed and can start her up!mmmm dual ball bearing goodness! :twisted:

its seems to be much larger than the old turbo, not much clearance behind the engine to bulkhead heatshield! :oops: but at the same time :twisted: :twisted: be reet!

been a ballache to match up to get it to fit, had to send it back to get holes redrilled, actuator bracket fabricated n all sorts, but the guys at CR Turbo's were legendary, cheers lads!

All fitted, just ignore the red reducer hose, need to get hold of a black one but needed one asap as clio needs to cover the polo now its headgasket has now blown so need clio next week for work! :shock:

expecting the full 250bhp to start of the generic fastchip, then proper map to bout 300 i hope after engine run in!

just clocked your willy conversion paush mate, same turbo am runnin, its a tight squeeze! pain in the arse these cars turboed, but kind of fun! :twisted:

You are unlikely to get a 'reliable' 380bhp with a gt28rs. 350bhp is about it's 'efficient' limit from what I remember. You may find in the clio engine bay it's less than that thanks to the lack of space means it heats up a lot quicker. Do everything you can to keep that turbo cool :)

Get it custom mapped from a decent tuner as well.

Matthew

cheers mate. will do. henk is coming over to map it . have been told 390bhp might be achievable. but ask coops. these things are rapid with 250bhp. so might find its undriveable over 300bhp. but want the engine mapped to see what it will do then find the best compromise for every day usage.

I'm not saying it won't do 390bhp, and you may even manage to get it mapped for that. What I'm saying is that the turbo is 'unlikely' to keep it up. I.e. if you blasting around a track with your car your turbo won't keep it up, or anything other than a short motorway burst. The more you push it, the more it's a diminshing return.

350bhp in a clio turbo will be a bloody quick car. If your pushing it beyond 350 I would really start to ask about what intercooler your running, how much of it is exposed to be cooled, what clutch you are using and what size injectors are you running.

I don't know how the clio engines respond to turboing in general, but I honestly doubt your gonna see 360-370bhp let alone 390 on a gt28rs with the restrictive exhaust manifold your using.

I will reiterate what I said before in another thread. 2 bar boost is a hell of a lot of boost to be running (especially on a standard head gasket!), and would ask how reliable you want your clio to be?

Scougar

:D good good. ARP stuff is bloody expensive just for bolts, but so worth it if you run a performance engine.

Good luck, and just take your time with the mapping (or book enough time for the company to do the mapping). It is expensive, but if they try to rush it, they could screw your engine up, or simply do a bad map.

I don't pretend to be a turbo god or anything but you pick up a lot of stuff when the modded car you own is inherently a turbo (from the manufacturer). I used to own a metro turbo, and that lot treated it like it was some 'black art'. They didn't have a clue really. I bought a 200sx and the turbo world was so blindingly obvious. Takes tuning to a whole new level of, well .. ease really :D

Prepare to have larger fuel bills even when just pottering about. 22-28mpg is common for turbo'd cars when not on throttle.

coops,how did u manage to do the bottom two manifold/turbo flange bolts up?mine need tightening but i cant find an easy way to get on them. :?

AndyFielder

12-09-2007, 15:18

coops what diameter tubing you using for the air piping etc?

Coops

12-09-2007, 20:30

all induction hose is 63mm internal bore mate

bottom two bolts were done up from under the car before drivers side driveshaft was reattached :wink:

tbh i want double valver power off a proper on the RR chipwizzards remap, so 276bhp, and that'll so me, even now on 10psi of boost, slipping clutch and 250bhp off the shelf chip its fast as **** and scares the shite outta me! so with 21psi, custom map and a paddle clutch its going to be more than enough!

reliabilty doesnt really bother me too much, so long as nothing massive gives out, H/G's i can live with, am thinking copper job next with the ARP's neils on about maybe! have a second engine am thinkin of building up to a better spec, not for more power but for more reliability

chargecooler setup we run if working efficiently is theoretically good to over 400bhp, as is manifold/downpipe combo. limiting factor is space for turbo and turbo size and H/G strength. :oops:

AndyFielder

13-09-2007, 09:04

woo.. got it right, im using 2 1/2" tube with 63mm elbows etc.

What A/R's are the compressor and turbine sides on ur new turbo?

Paul

Scougar

14-09-2007, 10:54

Your major problem is gonna be traction with anything close to 400bhp. I would stick the best rubber on her you can get your mits on. If you get a bigger turbo all that's gonna happen is lots of lag, and a massive torque spike, and completely undrivable except on track. Your current turbo should spool up pretty quick depending on your cams and give progressive power upto 330-350bhp. That's were I would be aiming.

A paddle clutch is gonna be a nightmare in traffic as it is, don't make things worse for yourself buying trying for big numbers. A more drivable consistent car will nearly always beat the big power hard to handle beast.

It's perhaps a wise move to build up (or make money available to) a second engine.

as i said mate, double power, so never going to be more than 300, its laggy enough on this turbo and to go any bigger requires a massively modified manifold to move the turbo to space further up behind the engine as thats the biggest turbo that will fit on this manifold setup. my cams are standard which is an area that needs addressing as currently as said the turbo is quite laggy, more so than my old one, so i need to sort a more progressive torque/power curve like u say

i have to use a paddle clutch, i am currently running the highest rated 'standard' clutch type and it lasted to my old low boost 217bhp setup with 176lb/ft of torque, i have driven it for 600miles on the 250bhp/250lb/ft chip and its slipping like mad already, so its simply not able to cope with the power.

already have 2 spare engines in the shed to tinker with, plan is to build one up as a low boost bottom end for emergencies as i still have chip etc to go back to that if necessary and the other for spares. then i can run the low boost while i repair the high boost lump, no way i can afford 2 sets of wosseners etc etc! :wink:

Scougar

15-09-2007, 18:43

If your on standard cams the the lag could be your problem there, as it's meant for above 4.5k and higher revving on standard cams? The gt28rs should be coming on full boost by about 3.5k realistically. Perhaps in order to get it up quicker you need to get it to spike "a little", but cams are definately gonna be needed to change the characteristics of the power by the sounds of it. I would be aiming mid to high revs as with the restrictions of your current manifold, most efficient power will be from the mid range (and then I expect it to tail off slightly with your current exhaust manifold). So basically your prob looking to lower the power band....

Good luck with the clutch :) Don't skimp on the mapping either.

im very interested in the arp head bolts as i think im going to be doing alot of head on and off again work on my engine as it gets upto spec.

do you reckon a pair of williams cams would do much?

Coops

16-09-2007, 16:05

well they are supposedly wilder than valver ones so if i had em when engine was in bits i'd slap em in! i know u need high lift short duration for turbo, so not sure which is best for that?

midge

16-09-2007, 16:15

im sure willy cams have higher lift than valver..

Scougar

17-09-2007, 08:11

Can't help you with cam choice unfortunately, not really looked into cams.

Just remember, driving turbo with anything other than REALLY short intercooler pipework will feel slow on the pickup to start with. You will soon get used to that however and just get into the habit of predicting how the boost comes in. Soon as you get above 1 bar mapped boost, it should really feel like a strong engine. Lower it to 0.7 and it might feel a bit disappointing.

Good luck with the mapping coops, and well done for such a good job so far :D (Oh, and make sure they map it for the correct fuel/air ratio for power and not for economy lol).

we need some dyno printouts of these turbo clio's. mines a few months off and ive got a lot of people doubting the performance figures. if anyone has any printouts please post em up so i got some back up until mine is done and i can wipe smiles off instead of just talking bout it.
