Well i thought it was about time i put together a project thread for my car, so here goes...
After buying the car back in March ive been making a few tweaks to get it to its current spec.
I bought the car as a low pressure turbo 172 cup running a very small amount of boost due to a weak actuator spring. It was rolling roaded at 210bhp, but still went nicely. The car had a PAS leak, and needed a new clutch so I sent it off to Fred @ BTM for the work to be done. Fred had all the manifold down pipe machined for me whilst the car was there as there were a few leaks around these areas and now looks the business. After getting the car back i discovered the turbo needed a rebuild. I spoke with my mate Andyrg who originally built this low pressure turbo conversion and we arranged to get the turbo rebuilt and have it remapped by his trusty mapper Andy Carr (www.teamcarr.net). After a few lengthly conversations we decided it would be rude not to make some adjustments to the internals. We decided on putting a set of F4rt pistons and rods in from a megane 225 in which i bought from Gray on here. This coupled with some brand new genuine renault piston rings, ACL Race bearings, ARP Rod bolts and a newly built GT28RS should give me a fairly safe 300bhp clio.
Once the car was sent up to Andy i had spoke with Chip about the turbo being rebuilt and after him recommeneding Vince @ CR Turbos, Andy whipped the turbo off the car and sent it off to them. I got a call from vince the morning after Andy had sent it and within 24 hours the turbo was stripped, rebuilt, and posted back to me. Absolutely first class customer service!
Next was getting the pistons and rods in. Andy noticed that the piston rings were well used so it was a good job we got some genuine rings from renault to put into the build. As we were going to be running more boost a fuel pump and pressure regulator set up was bought to work along side the new internals. Andy got a new megane headgasket so that the compression was the same as a megane and then had the car road mapped by Andy Carr. Andy put 4-500 miles on the car with a combination of mineral oil to bed things in and 10w 50 oil before having the mapping carried out and giving it full beans. Once the mapping started there were a few issues with getting the ECU to work with the 3 port boost solenoid, so for now Andy has put a manual boost controller on. Once up to temp the actuator spring is struggling to hold boost, so i have spoken with Andyrg again and we are toying with the idea of going with a 1 bar actuator, leave the 3 port boost solenoid and then finish the mapping off on a rolling road for a final figure. The other option is to get a new 7-8psi actuator and then play about with the ECU so that we can control the boost with the throttle like Chip has on his ph1 turbo.
I got the car back from Andy at the track on the afternoon of the Renaultsport Track day at Bedford. When i sent the car up to Andy, it had a full Yozza race system on which Andy told me along with the de-cat and running 1 bar of boost would struggle to meet the strict Bedford sound regs which worried me as it was getting close to the day. So, I phoned K-tec and spoke with Shaun who got me a brand new Ktec Stealth system with centre silencer sent out that day to arrive with Andy on the Weds before the track day on Friday. Andy got this put onto the car and called me straight away to tell me and i quote "he no longer feels like a 17 year old chav" driving my car about haha! The exhaust now sounds perfect IMHO as its not too loud and has a nice grumble to it when giving it some. With the de-cat and turbo the cars static test @4,500rpm came out at 85db
RESULT!
So... the moment of truth then came with taking it round the track for my first drive since the build. Andy told me that as its only done around 700-800 miles since the build i should take it steady and keep coming in after 2-3 laps to check coolant and oil. So off i went on a few laps in it wanting to see how different it felt with the extra power. At first it was brilliant loads of power, boost was holding around 8-11 psi but that soon changed with the weak actuator and scorching heat the car was only holding 5-7psi once on full boost, this i think was to be expected. On my first lap i had a black 182 sat on my backside which worried me, however once returning to the pits i found out it was Domsclio182 in his S/C clio so not too downhearted! Overall though im pleased to report that the car ran faultlessly... no oil was used and coolant remained stable even with the 29degree heat, the car felt really quick and seemed to go well too!
In conclusion then, Andyrg has built me a really great car that only needs a few tweaks to be completely finished and running circa 300bhp
Over the next week or so il be talking with Andy and deciding what route to go down, so look out for the final updated producted with bhp/torque figure with RR graph!
Thanks for looking
