Well all,
Myself and a mate are building 2 rx7\'s for Prodrift next season and they need to be ready by March for the licence day here in Ireland. We are building them from the ground up and have been advised to lose the twin turbo set up due to when the second turbo kicks in it would be too much to control going into a drift !
The goal is 400rwhp so here\'s what we were thinking :
Going for a street port, uprate the injectors, fmic, rad and single turbo conversion.
With regards to the injectors what would be enough to fuel this sort of power ?
FMIC, Which one ? Possibly a V-Mount ?
Radiator, dual or triple core ?
After a bit looking around i have seen the following turbo produce the power we\'re after but which would be most cost effective and also stand the punishment of drifting ?
GT35/40
HKS T51R Kai
Trust T78 33D / 34D
T04 E/ R
Sponsorship welcome LoL :Giggle Seriously all advise is welcome and greatly appreciated !
Brendan.
P.S. We already have the apexi power fc\'s and commanders on the way from japan and we\'ll more than likely be going with the kaaz or cusco 2 way lsd. Clutches are a mystery at the moment !
The second and third turbo\'s you mention are wayyyy too laggy I think, I dont know about the other two, but you may want to look at a non sequential twin setup, either with the stock turbo\'s (save you a lot of money) or some uprated ones. You might not quite hit 400rwhp on stock blowers but it would be close, and power out of a rotary is hard to directly compare to piston power, you might find 300hp plenty for the job.
Um offhand I know a t70 would hit 400hp and have less lag than those mentioned, thats the main plan isnt it, to get rid of the lag? Plus it is very sturdy.
You should get 400hp from 1650 secondaries and stock primaries, plus it will keep it a bit more driveable at low revs.
I\'ve no idea about the IC, rad setup that would be best, a v mount might be very pricey if you prang the front, whereas seperate rad and ic would be easier/cheaper to replace/fix?
Good luck with the project and make sure you keep us all updated, there\'s not enough drifting on this forum! :)
400rw is kind of alot, you may want to look at one of the Bigger RB Turbos (To4Z or GT40R)
aparently the GT35/40 (it is a ball bearing turbo) is not a good turbo to go for on a rex as i was adviced against getting one as the ball bearing dont seem to be able to cope with the heat. i went t70 instead.
Ok, try telling that to every one using them :)
The only thing wrong with the GT35/40 is they need an Oil restrictor to run on a stock engine becouse they get over fed with oil.
there are advantages using a plain bearing Turbo, they are cheaply rebuildable!! a Rb core can cost anywhere fro £500-£800 plus fitting :yes
lol, if pip had ordered me one from his turbo guy, it would have come with no sort of waranty at all, and the turbo guy advised against it.
i just go on what i am told, i wanted a RB turbo, but was told that it was best to not, well not this one anyway (but surely there is different companies making GT35/40\'s i dont know which company the one that i was possibly going to get was made by)
Ok, Gt Turbo\'s are a Trade mark of garrett (the Best manufacture)
I\'ve heard all sorts of things tbh about RB turbo\'s but if they are set up correctly with the right Housing size etc there is not usaly a Problem?? But as i say they cost alot to put right if some thing small goes wrong with it. All it takes is the wrong Oil flow Restrictor and you can seriously harm one.
Don\'t forget Turbonetics gave RB Turbo\'s a realy bad name in the begining by selling turbo\'s that where effectivly a plain bearing turbo with a Roller bearing on the Cold side (so they where half RB\'s if you like) and they where Poor and had bad reliability.
my personal choice for drift would be:
Greddy TD06-25G or Garrett T04S as this kits ar chep and easy to rebuild. (T04S)
You dont need 400 rwhp to get drift. 400hp at fly are fine in my oppinion.
You can try T04E with 60- comp wheel. Should give you some nice spool-up and enough torque for drift and fun.
Just my 2p.

TD06 or Apexi RX\'6
TO4Z, half bridge port, no lag, 450rwhp potential.
Ant.
These cars will never see road, only track for drifting and possibly time attack, more for drfiting however ! Hence the reason for such a high rwhp... We want to have the most fun possibly !
@ A7NTY : If the car in the avatar is you its amazing, i was only reading the feature on it for the 3rd time last night !
Have sourced a very sound fellow is build radiator\'s for a living and is willing to build us triple core rad\'s for next to nothing !
yup thats my car, thankyou :)

Sounds good to me :D
@ A7NTY : You welcome, amazing machine, i\'m awaiting delivery of my scoot cf bonnet at the minute, your car sold me on the bonnet, dam you LoL
I know i don\'t need 400rwhp to drift but i want to get more use out of the car than just drifting !

So could i use the stock turbo\'s rather than go single unit ? Would this be a viable option for drifting ?
I would have thought stock turbos would have been better for drifting. But then again, ive never tried it:2Rolleyes :Thumbs-up
I thought so aswell however when the second turbo takes over it might be to aggressive mid drift no ?
Presumably though you need smooth delivery across the rev range rather than the \'bang\' you get when the second turbo kicks in.
Unless you go non sequential....but thats a different story...
I think twin turbos, when they\'re operating like they should should not produce any violent BANGs. Sure, its a little kick, but you should be able to compensate for it if you are willing to learn. And on the up side - if you stay above 3000 RPM once you\'ve been into sequential operation after 4500RPM, then you should not get another kick if you plan to go with PowerFC. See, PowerFC doesnt switch back down to primary turbo once the revs drop under 4500, it only does so when they drop below 3000. And this is a setting you can change I heard.
I think twins would be perfect for drifting. If you go single, you will have bigger lag and no power under 3500RPM.
Dont throw away the twins idea until you try it. They are wonderful when they work.
I have 360hp on the fly and that is on stock injectors. With powerFC and some fuel mods, ported engine, 400fly hp is easily attainable.
Thanks cruiser, thats exactly what i need, info from people who are actually running the set up\'s...
No offence to anyone but r&d can be very expensive espically when going from twin to single turbo...
Its starting to look like i could save alot of money staying with the twin set up.
I say at least give the twins a shot. If you find it too problematic to hassle with the sequential system, you can still convert them to fully non-sequential and you will have almost single turbo like FD. Drifting is not about power, but handling and driver.
I\'ve a few mates in Prodrift here in Ireland and the chap that tunes my cars looks after 2 of the cars in the pro series... Everyone uses the SR20\'s, picked the RX7 to be different.
The reason for trying to figure out what set up to use is down to the intercooler / v-mount. Don\'t want to be waisting money from the start that i can use for tires, clutches, gearboxes etc...
I\'m guessing at this stage the TT setup would be easier just more difficult to master...
Cruiser is 100% correct ... Drifting is not about power, but handling and driver and Set up !!
Darren M has a Carolla .. running 160bhp on N/a .. Did very well in this years D1 . and doesnt have a problem against some of the 400bhp+ 200sx\'s and Liners.
I would say go twins Non sequential why not ... or single Garrett T04S or TO4Z
Quote from: Sy.Darren M has a Carolla .. running 160bhp on N/a .. Did very well in this years D1 . and doesnt have a problem against some of the 400bhp+ 200sx\'s and Liners.
I think he has an SR20DET uner there mate and it is more like 300BHP :evillaugh
Darren McNamara is running a corolla with an SR20 since the start mate, he\'s pushing over 300bhp with anti lag !
And yes its about correct set up and skill but this is why i\'m asking what would be the best single turbo unit for drifting !
Kieron beat me too it LoL Darren only lives 45 mins away, his next corolla is going to be even more powerful !
they were saying at Silverstone how he only had N/a 160 or 180 bhp ... as that is why he was not initiating the drift as fast as the others and was getting an advantage as they had to slow down and not get as good a drift . It was Europe v Japan event .
Edit - just asked a mate who i went with and un suprisingly i heard wrong !! lol it was Ueno running Ae86 with the 1.6.
Check it out for yourself :

@ Sy. : I often hear wrong too hence why i try and get advice on forums, at least its in writing when i break engine so i can only blame my lead right foot !
it was over a loud speaker in one of those box\'s and i just saw a Ae86 so assummed it was Darren... as they had simular cars .. well you get the rest . :D
With the mods I listed, you should be on 350fly hp with like 1150kg when you strip it out. Seems a good drifter for me. Although the car isnt the easiest to drift. It definately takes more skill as compared to say E36 M3 to do it smoothly.
I speak from my modest experience ;)
Cheap and reliable single...To4E.
Excellent mid range torque on a street port, and does not peak too high. When mapped properly, will give in the region of 380atw with 1.1bar-ish.
Cheers,
John
Thanks for all the info guys, out smartfilter in work blocks alot of sites even google and since i\'m here nearly 12hrs a day I don\'t have the time or energy to be on a computer outside of here !
I think I saw a T04 kit on nengun.com / could have been takakaira thou i\'ve looked at so many sites the past 2 weeks !
