Guest J O H N S O N Posted January 23, 2010 Share Posted January 23, 2010 Hello Guys Will EUspec Turbo fit right on a Japs Spec ? Without any mods ? Thanks Link to comment Share on other sites More sharing options...
Kirk Posted January 23, 2010 Share Posted January 23, 2010 correct me if im wrong BUT arnt EU spec turbos 4 bolt mounting rather than 3 bolt on the j specs? i think you would need the manifold aswel Link to comment Share on other sites More sharing options...
Ian C Posted January 23, 2010 Share Posted January 23, 2010 Have a search of the technical section for what you want, it's been discussed in quite some detail. You certainly need more bits, like the exhaust manifold and I think downpipe. It's also regarded as a backwards step. Link to comment Share on other sites More sharing options...
Guest J O H N S O N Posted January 23, 2010 Share Posted January 23, 2010 Okay - Thx Guys Ian C - Whay is it regarded as a backwards step ? Link to comment Share on other sites More sharing options...
Ian C Posted January 23, 2010 Share Posted January 23, 2010 Heavier impeller, so therefore slower spooling turbos. The ceramic j-spec spin up a lot faster and are capable of flowing good power at BPU levels. Again, a search will find probably more discussions on this than you ever wanted Link to comment Share on other sites More sharing options...
Kris H Posted January 23, 2010 Share Posted January 23, 2010 but the steel impeller blades can take some more abuse yes?? Link to comment Share on other sites More sharing options...
Kris H Posted January 23, 2010 Share Posted January 23, 2010 johnson,,I thought yours was a singel beast:search: but perhaps it's because of the mean looks.. Link to comment Share on other sites More sharing options...
Homer Posted January 23, 2010 Share Posted January 23, 2010 but the steel impeller blades can take some more abuse yes?? Not exactly. If you wish to go beyond 1.25bar then the UK's 'tend' to be okay to 1.4 bar. However, if the car is jspec with the jspec ECU and injectors you will not see any benefit since they will be at capacity far before the UK peak boost pressure comes into account. As Ian has mentioned, it'd be a backward step to install UK turbo's on a Jspec car without having larger injectors and a mappable ECU. Even then the difference in peak power is minimal at best. The drop in spool (which is what makes the jspec 'feel' so quick) will be lost forever. Link to comment Share on other sites More sharing options...
Guest SupraGTE Posted January 23, 2010 Share Posted January 23, 2010 BTW whats the price for new Jpsec turbos? anybody knows? Link to comment Share on other sites More sharing options...

Guest J O H N S O N Posted January 23, 2010 Share Posted January 23, 2010 Kris H : My car IS a Single turbo Greddy T88 - With 800 HP But the danish MOT and Tax is fucked :S And giving HIGH fines to tuner cars :/ So im going to put in a BPU Japs spec .... But then the best IDE is to run the Japs spec Turboes - at maximum 1.2 bar ? Link to comment Share on other sites More sharing options...
Kris H Posted January 23, 2010 Share Posted January 23, 2010 ahh i see,, i would keep the jap's on then.. but eu-spec turbo swap is regarded by some as a fine mod ,, the last step before singel you might say.. also why johnson is doing it i guess???

Guest J O H N S O N Posted January 23, 2010 Share Posted January 23, 2010 I have just heard that they should be more durable and hold for a slightly higher pressure ? ? Link to comment Share on other sites More sharing options...
Kris H Posted January 23, 2010 Share Posted January 23, 2010 Kris H : But the danish MOT and Tax is fucked :S And giving HIGH fines to tuner cars :/ like csa Link to comment Share on other sites More sharing options...
Guest J O H N S O N Posted January 23, 2010 Share Posted January 23, 2010 Yep - we are talking about Fines up to 30.000GPB :/ Sick Link to comment Share on other sites More sharing options...
Kris H Posted January 23, 2010 Share Posted January 23, 2010 has he got his car back yet ?? Link to comment Share on other sites More sharing options...
Guest J O H N S O N Posted January 23, 2010 Share Posted January 23, 2010 Nope not yet But I've got an answer from the tax that is legal with the engine conversion ... they contradict each other at tax offices ... hehe so it helps him in his case :o) But I dare not take the risk Link to comment Share on other sites More sharing options...
Guest SupraGTE Posted January 23, 2010 Share Posted January 23, 2010 Im in the same situation almost as you , not high fines as 30000gbp if you buy j-spec turbos and you end up rebuilding them you will end up with steel blades also ,so then the + with j-spec in IMO is a bit gone, Link to comment Share on other sites More sharing options...
Guest J O H N S O N Posted January 23, 2010 Share Posted January 23, 2010 after this thread - I guess I just keep my JAPS Spec:o) Then I change them if they go to pieces .... They're probably easy enough to find Link to comment Share on other sites More sharing options...
Homer Posted January 23, 2010 Share Posted January 23, 2010 My car IS a Single turbo Greddy T88 - With 800 HP But the danish MOT and Tax is fucked :S And giving HIGH fines to tuner cars :/ So im going to put in a BPU Japs spec .... But then the best IDE is to run the Japs spec Turboes - at maximum 1.2 bar ? Ah, I see, what a ball ache, feel for you guys What ECU, injectors and cams do you have now? It'd give a better idea as to what stock turbo choice would be most suitable. The export spec ECU and Jspec are not interchangable for many reasons.

Kris H Posted January 23, 2010 Share Posted January 23, 2010 (edited) JOHNSON: But I've got an answer from the tax that is legal with the engine conversion so i've heard.. cant he use that to avoid additional taxes and fines Edited January 23, 2010 by Kris H (see edit history) Link to comment Share on other sites More sharing options...
