Hello

How much power can you get from a twin turbo setup??

Reason is i was looking to sell my rex, but hopefully!!!!!!!!!! now i can keep it ££££££!!!!!

Ive done the exhaust, air filter, pfc, boost controller and it is running 277rwhp at about .8 bar.

Whats my next step??

Intercooler,
porting,
hybrid turbos??? etc

Before you say single turbo, too much money!!!!!!!!!!!

If anyone can help thanks.

If you cant, bugger.

Intercooler , bigger injectors, better fuel pump, possibly a modded fuel rail, more boost, Remap, Water/alch injection etc etc.


I have seen twins up 400whp. the limit of the seq turbos is about 380whp roughly if you check the compressor map.

sdminus@yahoo.co.uk if you need any help

You should see around 320 reasonably easily. Some of the modifications you need will be reliability based rather that power.

Intercooler
Cold Plugs
Good leads
Porting
Fuel pump
Bigger injectors
HKS Twinpower
Clutch (it\'ll need it very soon if its not already uprated).

If you can\'t afford a single turbo, then you can\'t really afford to cook your turbo pack, so I\'d keep the boost around 1 bar or just under.

Likewise a hybrid turbo kit, by the time you\'ve messed about with that, then realised it isn\'t much better than the stock twins, you\'ll kick yourself for not gettting a single turbo kit instead!

You should speak to Warthog. He\'s go the most power out of his standard twins than anyone else. Over 400bhp iirc
He\'s not on here as much as he was but try PMing him, i\'m sure he\'ll be happy to give you some advice

I was running 327.8 rwhp at .8.

Mods: Street port, straight through, downpipe, filters, uprated intercooler, Apexi ECU and a WGT map.

Without frying your turbo\'s you will quite easely see 320ish, the bigger power numbers on twins tend not to last to long.
Realy depends on what you call big power, 300+ is more than ample to scare most other street cars off :)

Thanks for your help!!! how much can you get single turbo kits for???? Im guessing around £3000. Where can i get the best price for all the things you have suggested??? i.e Intercooler etc

I think check any of the vendor links at the top and they should be able to sort you out. Failing that ebay or places in the US :)

I\'m doing the same as you and want to stay twins for a long while as single is lots of money.

If you dont mind the hassel and are happy to deal with companies abroad, I would try Horsepowerinabox, Austrailian company they sell the complete kit providing different levels of power and depandant on the state of tune your engine is, or you can spec up your own turbo. The good news is that the exchange rate atm is very good, bad news - dont forget to factor in import duty / VAT, postage ect.
If you are determined to go for big power, I would save your pennies, go for a re-build and include a BIG port in the deal, that way you wont find yourself short of puff and on a fresh engine you can expect plenty of trouble free motoring [read ragging :yes ], just bolting on the ancillaries is not the answer, especialy if you are after big numbers.

You can get them for cheaper than that matey, speak with some of the vendors at the top of the page about what they have, you might be suprised what you can afford  :Thumbs-up

I was only hitting 293whp when i was at Pips on friday. Recond turbos, street port, HKS filters, big HKS front mount, Attain straight through, 3" downpipe, Power FC!

How are you guys hitting 320+!

I only saw 301.7 on pips dyno, saw a little more a thor (as did you) so 320 atw isn\'t a big issue. But all i would say is go for the intercooler and bigger injectors first before thinking about going single. At least it will be in a better position when you finally go the whole way. I think with mine i\'ve got original turbos because it runs out of puff at 1 bar and im currently at the stage of looking for a big single. Been taking some serious interest in the GT35r kit from Rx7store too, as said exchange rates are very good at the minute. I\'ve asked if it fits a RHD car and they have said yes ! But all in saying you need to factor in all the bits that the kits don\'t include because they are far from complete.

I\'ve been reading up on http://www.negative-camber.org/crispyrx7/gt35rpage1.htm
and i think you need a budjet of a few hundred quid to sort all the rest out.

What boost were you running rix? Sounds like under 1bar? and if Pip tuned it i heard he likes to play it safe with the mapping too but that could just be hearsay?

Matrx, I\'d stick with the twins and aim for 1bar for now, which will mean you can keep the stock injectors and still get good figures without porting, and probably wouldnt need an ignition amp, just uprated fuelling and a large IC, or Charge Cooler, new clutch, and running 10s or colder plugs with good leads. Then when the turbo\'s \'give\' .. look to buying a small to medium single. Might be surprised at how quick the low 300s in these car\'s feel.

Running more than 1.2bar is asking for trouble in my opinion, might look good on the dyno, or the strip, but you\'re dicing with turbo death which is a bit pointless tbh unless you\'re waiting on buying a single and looking for an excuse :)

Oh and mines running on completely stock ports on the engine and the turbo !!!
