[score1_uk]

Right, Im about to place an order for the following list of parts:

HKS Full Turbo Upgrade - MAZDA (T04E w/ Racing Wastegate)

APEX INTERCOOLER KIT (for RX-6 Single Turbo Kit)

GREDDY BOV for Mazda RX-7

HKS TYPE-1 Turbo Timer

Will these parts go together ok? and any1 care to estimate what BHP I should be gettin about?? (other mod is Blitz EVC, all ready on the car).

You may need to improve fueling.
Uprated pump / injectors.

You can get 350 from stock turbos with similar mods so I would hope you could get 400 (at fly) with single turbo.

I won\'t need new injectors, and the Power FC will do the fueling. (I think)

The main thing was the intercooler with the HKS Single Turbo conversion, am hoping that they will be ok together.

Im no expert but i would say you will need new secondary injectors...

good luck with it.

[sadgoth]

If you have stock injectors you won\'t be able to get big power out of the car unless you upgrade them. The PFC will control the fueling but if you have the stock 550cc injectors and fuel pump then the PFC can only push as much fuel as the fuel system will allow and 550s won\'t allow enough to rund that setup at a high boost.

ok, so I could run on the current injectors 4 a bit at about 400BHP, then replace them with new pump aswell.

What are good parts to use?? where could I get them??

Im wantin a 1/4 mile time in the 11\'s out of the car.  I last got 13.68

At least 1300CC secondaries matey;)

[Donato]

Yeah, but dont go anywhere near full throttle until you have done the injectors and pump or you will be to lean, i certainly wouldnt try and beat your current best time until you have, believe me, i learnt the hard way at rotorstock last year going up the strip. quite a few thousand pounds later im now ready to go up the strip again..

I got my injectors and pump from WGT, there are other places, do a search and you should find loads.

[score1_uk]

If I replace the secondary injectors, do I have to do the primary ones aswell??

[Donato]

I only replaced my secondaries when i did my conversion. I have 1300 secondaries, and still have 550 primaries, i would give one of the tuners a ring for advice, Pip at WGT is a very friendly helpfull guy, give him a ring... the man knows what he is talking about.

The primary injectors are not as important but if you wanna run 11\'s then possibly 850 as primary and 1300 as secondary if in the future you wanna run even quicker then by-pass the 1300\'s now and get 1600cc injectors as secondaries.

Hello mate...

Right.. i have just fitted a to4E.  It comes with all the pipe work to fit to a standard intercooler.  I have a feeling these intercooler kits that are designed for single turbo\'s don\'t come with a pipe to the turbo, you are left to fabricate your own......so i ordered a greddy intercooler kit for standard turbo\'s,....  seems a long way round to the turbo but was told by a few tuners that it won\'t make that much of a difference.  See pic below.

No point cutting corners mate.... i would fit 1300 secondary plus an uprated fuel pump.

well, the goal is 600BHP in this car:

[Adam]

doubt you will get 600 then mate from a to4e.... be lucky to get 450 to be honest.

and I don\'t wanna blow it up (or kill myself) in doin so.

I think I\'ll look at prices and go 4 the sec. 1300cc injectors, and a fuel pump (what press will I need?)
