What in the name of ................gta Turbo ?

YAWN , YAWN , I just thought it looked like an interesting car from a tuning master . A kelvedon classic.

YAWN , YAWN , I just thought it looked like an interesting car..... definately....... but he's just chucked it in a rusty subframe etc so it needs stripping and rebuilding....should have done it right inthe first place


from a tuning master . A kelvedon classic.

the king of the big white wheels

If there are flakes of white paint on the subframe then its my old one . I have no idea where the Hammerite/Powder coat item came from that apeared on my car during the rebuild . Does it look happy with a new engine sitting on it ?

Is the shell Peter G's old car?

Don't put in 5th then
I know I can't ever get there on track

He said that the americans rarely break 5th 'cos they're not allowed to go fast enough!

Simon, ahem http://www.renault21turbo.com/forum/ your lost again mate!

Its about putting a J7R into a GTA the fact that it is a 21 lump is neither here or there its just an all alloy engine that sombody has developed at great cost !! but now the development has been done it wont cost what it cost him.

Tony the whole point is that it wont cost £10,000 probably about £3,500ish including the turbo and setting up. The turbo a T28 and if you got the 3" down pipe spinning it up not a problem. I wouldnt put a Pinto, Cossie or not in the back it weighs a tonne as do most 16 valve twin cam lumps.

My 21 produces what it produces and I wouldn't personally bother throwing any more money at the engine as it cant put the power down its got . I love GTA's I love the V6 thats why I bought two, I have been an owner for about 4 + years and only done 4 small laps at Brunters. My Atmo no engine lid and perfomance filter sounds great....no stereo required.

I am hoping that reasonable power is acheiveable cos I want it too

I already walked away from the J7R conversion because of financial and practical reasons at the time, but, I just thought it would make a quick interesting car that may be have more balanced handing. Dont you jsut love the way the 110 hangs its ar se out


Big Mart i expect If i went on about the 21 turbo lump in a GTA on 21TOC they would tell to FARK off too its a bloody GTA thought you lot would be a little more open minded being and older crowd



si21 I wont mention it again EVER

Heres the advantages of this car over the V6 Turbo

Firstly, on standard spec this engine can make 230bhp, at around 17-18psi. We've seen standard GTA's running a bar of boost, and still struggling to make standard power, 200bhp.

The engine is sooo much smoother running than the V6 turbo. None of that horrible shudder through the revs when you rev it like the V6, none of the shudder transfered through the gearbox too, like when you slip the clutch in in first. None of that lumpy idle as you get on the V6 turbo. It also revs far quicker. Throttle response eats the V6 too, plip the throttle and it revs as a normal engine should.

Massively less turbo lag than the V6 Turbo, due to the turbo being directly mounted on the head rather on long tubes like the V6.

Far less underbonnet heat.

No dodgy sensors and looms as plagued the V6 Turbo

Again the weight difference. The old weights journal puts the bare weights of the Douvrin 4 and the PRV at 120 and 170kgs, but then the V6 turbo has the pig iron manifold backplate and turbo, downpipe and heavy exhaust silencer, intake pipes etc. This conversion has a very small lightweight exhaust and the only extra weight to the bare engine is the weight of the turbo. The V6 turbo silencer is way over 25 kilos, and the back plate weighs a good 7kgs, so the true weight difference is about 80kgs and bit.. Thats like an 13 stone man taken off the rear wheels of your car, and the remaining weight sat lower in your engine bay.

Cooling wise...well now you have the massive cooling system on the GTA, cooling a much smaller engine and thus coping much better at it.

What else, ahh the engine sounds nicer, its a smooth deep note, and the physical engine sounds nicer as its cambelt, not chains, no oily messes, no rattly engine sound.

Gearbox wise, this car has the atmo box, so the 4th and 5th gear ratios are faster than the Turbo box.

Clutch is lighter too...

Car runs a brand new Walbro 255l/hr fuel pump.

Servicing, everything is far more accesible. Slave cylinder, oil filter, plugs, EVERYTHING. Everything thats difficult to get to on a V6, isnt on this engine.

Tuning wise, as Si said, you can change the cam easy, off the shelf ones are available. No agro with the pain in the ass cam timing issues of the V6. ECU upgrades are straightforward and already available, even the original ecu doesnt have the boost cutout like the V6. Even 250bhp has been acheived on standard engines, with larger injectors, slightly better turbo.

The only people in the club so far with V6's that have hit 250bhp have either A610's, spent thousands and fitted a 610 engine, or simply there isnt any others, as they havent spent what is required.

Infact, there is not one advantage the V6 turbo has over this. Not one I can think of.

If you take out all the sound deadening like Peter G did, you could get this car to 950kgs. If you have 230bhp, you'd have to have a 300bhp GTA V6 turbo to match it for power to weight, which so far, doesnt exist, would cost absolute thousands, would need every part of the engine changing, and also have lag lag lag lag..... still shudder and still rev like a lawnmower..

Don't make it sound too good or I won't be able to buy it cheaply when no-one else bids

Sounds fantastic , but then that's Dave's greatest strength .
Adaptronic was plug and play too
So why not finish it and find out what it really does put out and handle ?

Because I have moved on from owning GTA's, and have no interest in having another one. I will get the brakes sorted and have it MOT'd tho if someone pays the BIN price.

Listen, if my rusty old subframe that needed lots of new bushes is about to make Alpine performance and handling history then I want a piece of the action. Suddenly I am interested in all that technical thread stuff. Just how fast will a bit of my car be going ? The rest of my car is still in winter hybernation

Im confused, why would your old subframe be on this car, this has the original subframe on it. It didnt need to be removed to fit this engine. You had a new reconditioned frame and arms as I always fitted a good known exchange frame from stock rather than worry if the customers has any proper rot or beyond repair. Your's was mangled though.

Feck
All that 21 power being put through a knarly old rusty GTA frame

Only joshing Dave ,I'm sure it's tip-top

PS....I got my bits this morning ... BY 10 ( but it wasn't so I'd ask for some dosh back if I were you )
Why such a big box

Moving on, does this mean you're no longer goign to supply parts as well ?

No idea. I've always just used it this way.
