Euspec Turbo fitting ?

Hello Guys

Will EUspec Turbo fit right on a Japs Spec ? Without any mods ?

Thanks

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

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.

Okay - Thx Guys

Ian C - Whay is it regarded as a backwards step ?

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

but the steel impeller blades can take some more abuse yes??

johnson,,I thought yours was a singel beast:search:

but perhaps it's because of the mean looks..

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.

BTW whats the price for new Jpsec turbos? anybody knows?

Nic used to quote £1k each for them

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 ?

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???

I have just heard that they should be more durable and hold for a slightly higher pressure ? ?

like csa

Yep - we are talking about Fines up to 30.000GPB :/ Sick

has he got his car back yet ??

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

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,

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

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.

so i've heard.. cant he use that to avoid additional taxes and fines

I'm gonna have to move this to chat, guys
