single turbo?

[Rixio]

Hi...
 
I have a question about the single turbo conversion...
 
At the moment, I have a massive turbo on my FD, a T45R... with 1200cc secondary injectors, 400 ltr/h fuel pump and a "R Magic" ECU mapped by Jo Bounds in Japan + HKS GCC coupled with HKS EVC...
 
I find the T45R turbo too big for my kind of driving... i would like to have a more "flexible" turbo such as a GT35R...
 
My question is: Do I need to remap the car completely if I just only change the turbo (swap the T45R for a GT35R)? Or will i just need to adjust the boost controller and GCC (as the turbo will be smaller)...?
 
If I\'m wrong could you tell me which would be the best solution...?
 
I thought it would be best to post on this thread as it is the initial subject.
 
Thanks a lots.:cheers

A complete map as Nik says...i know a tuner that does house calls

OK... Thanks a lot...

I\'ll have to think about this then... not easy to find someone who can tune the ECU I have, over here in France...

And slight problem, I don\'t know which software is used to map / remap the "Jo Bounds R-Magic ECU"...

looks good matey but mates said i really shouldn\'t go to big as i\'m wanting to do hill climes as well as on the strip. hes on about getting me a Garrett GT T30. you know anything about them and if would suit car?

If you cant keep a T04S spooled up on any strip or circuit...you aren\'t driving properly, it gives full boost from 3000 odd to the 8K redline.  

T04S is a great turbo on several levels, cheap, reliable, cheap to rebuild.

In your shoes, I definately would not fit a smaller turbo.

GT30 is a pretty small turbo i think mate! T04S would be ideal for what you want!
Is your mate giving you advice familiar with RX7\'s?
I would imagine he is baseing his views on a piston engine! Rotarys provide alot more exhaust gas than piston engines and as such spool up turbo\'s quite abit quicker.
A small turbo that would be suitable for  lag free boost on something like a 200sx would probably be too small for an RX and you would "choke" it!

he\'s in to and done loads of cars eg skylines n evo ect but don\'t think he\'s had much to do with rex\'s. thats why i\'m asking on here just to make sure its the right turbo for me. i was thinking of a gt35r but he said was to big for my car.:cheers

GT35R is a PERFECT match for an FD3s, unported through to large street port.

i was looking for a gt35r and found this http://www.rx7store.net/product_p/gt35r%20kit.htm seems like a good price? was also looking at the apexi rx6 kit, both seem to have a good rep, but gt35r is cheaper.

I bought my tub from this seller

thanks to tell you the truth its been driving me mad everyone say different things. but the gt35 seems to be the in between one. do you know what sort of boost you can run? mine is street ported.. thanks jay:guinness

[strange_days_uk]

If you have the right mods ie fueling then I would think you could map to 1.2 bar +, although this would not be ideal for longevity of the engine.

You would be very pleased boosting around at 0.8 bar, maybe with high setting of 1 bar.

Trust me.

A safe map at 1bar should be sufficent with a GT35 :wave
