Turbo Conversion

[dansedgli]

Im just wondering if anyone here has turbocharged an NA motor and how it went? When the higher compression became a problem, what boost levels the valve springs needed replacing etc etc.

There was a bloke with an orange ute that converted his NA but never posted the results after it was tuned.

Ive got an NA motor in my EA at the moment fitted with an externally gated GT3540, custom exhaust manifold, intake plenum, 60lb injectors and it will most likely cop an autronic ECU.

Im trying to find out what to expect power wise as the engine will be standard when it finally starts up.

Cheers,

Dan

with an upgraded fuel pump and a good cooler you should see over 240rwklw, I would not go anymore then this unless you are going to pull the motor apart and do things like valve springs. your set up can go alot higher then this but the motor will not last long...

Cool, Ive got an 044 bosch in the boot.

The motor will be pulled apart eventually once it is all sorted and I know there are no issues. Do you think 300rwkw is too much of an ask with the higher compression of the BA motor if I do valve springs?

[DAWSEY]

on a turbo motor from factory 300rwklw is about the limit.

you can do it but unless you pull the motor down and freshin it up you will be on borrowed time.

what gearbox are you using??

5 speed manual will not hold that power.

4 speed auto will need to be built up to hold that power as well.

the magic 300rwklw mark is hard to get even in a turbo motor. but the good thign is there are alot of people doing it now so learn from them and you should be o.k

why are you going a autronic ecu??

[dansedgli]

Im using a TR3550 for now. It will likely be converted to a C series auto later down the track.

I dont mind the engine living on borrowed time, the car is a toy, not a daily driver or anything and it will be getting rebuilt eventually anyway.

I went with the NA motor in case the conversion didnt work out (the NA motor was $3000 cheaper at the time) and I had the turbo lying around already.

Ill either be using the autronic or Wolf V500 or maybe a motec M600 if I can convince myself the extra cost is worthwhile. The autronic seems like the best value so far.

I couldnt find anyone willing to setup the standard ECU and an edit for me despite everyone saying it was possible. I dont have the patience or the time to be cutting into looms and reading wiring diagrams experimenting trying to make it all work.

who is tunning??

if I were you I would find the best tuner and use what they think...

as the tune is going to be the biggest thing here.

even with 200rwklw a bad tune will go pop.

if it is a toy then look at an atomic bottom end when it goes.

then use your head with new springs.

this will be the best option.

I have seen these bottom ends hold 500rwklw

[dansedgli]

Im still unsure about who is going to tune it. Im looking to have the ECU done in Feb so Im still doing my research.

The atomic gear looks the goods, that is probably the path I will take when it is time to upgrade.

Do you know if the atomic cams you have still use the dual VCT?

The dual VCT is what is limiting my ECU choice. If I could make the power with new cams instead I could use any ECU and that would make finding good tuners easier.

[DAWSEY]

yeah they still use VCT

where are you located.

as there is a good ford tuner in every city now almost!!

[dansedgli]

Nizpro, dynomotive and MPC are all pretty close by so finding a decent tuner isnt a problem. I think Nizpro and MPC deal with motecs so they will be pricey. Dynomotive can do a wolf V500 at a reasonable price.

It will be interesting to see how it all goes on the NA motor. Hopefully the high compression doesnt hinder it too much.

Dan, if my old ED could take 15psi all day for a year without popping then I reckon your fine... you know what your doing mate, make sure it intercooled very well and spend lots of time on the dyno with a good tuner.

you'll make more with that turbo/manifold set up on 10psi than most of us xr6t owners could hope for.

What injectors you gonna use?
