anybody know how much it would cost to turbocharge my n/a. i did a search but couldn't find anything. would it be a good idea? is there someone on here who could do it? all comments are be much appreciated.

 

cheers

 

alex.

Did a search? Who you tryin to kid? LMAO

 

Do a search on http://www.twinturbo.net - not really feasible tbh. Sell it and buy a TT ;)

It CAN be done but I think you're looking at £5K odd all in - ideally you need a donor TT car and a decent mechnic for a week IIRC.

I might be wrong but I thought Karl300ZX had a NA originally...

These days its cheaper to get a TT and do refresh work on it.

Topless is the only one I'm aware of & he only did it because he had a convertible

(and could do it himself!)

I think this guy wants to know if he can add turbos to his N/a Engine?

You could do a low pressure Conversion but it would be better like suggested above if you just swap engines with a Donor TT :cool:

Eric (lymon) has turbocharged an NA engine, Mark (topless) has done a TT swap.

 

info for turbocharging an NA

 

info for TT replacement

>> You could do a low pressure Conversion

 

Not necessarily

 

I've turbocharged 3 NA engines so far and all run absolutely fine on stock TT boost (9 psi).

I've made a custom chip ( with mappings that suit the high CR), which took a lot of time to get right.

 

One of the turbocharged NA engines is in my own car and apart from experimenting with all sorts of boost levels, I have been thrashing it on the motorway, nurburgerring, rolling roads and it has been used as a daily car for over 2.5 years, but the engine is still in one piece and 100% .....it's actually the stock TT turbos that have given up :D

 

It's not so much the high 10.5:1 CR that's causing the limit on the boost...it's the fact that the 370cc TT injectors are completely out of juice at anyting over 11 psi.

 

As the turbos are now toast on my own car I will be putting JWT530BB tubs and 650cc injectors on it some time soon and see how long it will last

What about supercharging? That would be a good idea.

>> What about supercharging? That would be a good idea.

 

done that as well for one of our customers, but after doing it I wouldn't really recommend it unless you have won the lottery ;)

 

you'll end up with a car that will be very scary to drive in the wet :D

 

Supercharging works very well, but it is a VERY expensive option due to the cost of the charger itself and the custom parts that need to be made.

You'll loose the aircon, you won't be able to adjust the boost as easy as you can on a turbocharged car and the life-expectancy of superchargers is a bit of a problem (even worse then turbos)

But there was a reason Nissan used low compression on the TT!

I would have thought running 10.5:1 compression ratio would severly increase the chances of Det and a holed piston?

The N/a's also have difference port sizes on the heads and different material valves to the TT's for a reason.

Hence why i a suggested Low pressure turbo conversion! :)

lower compression on turbocharged engines is old school technology ;)

I know :)

The NA engine on 7 psi (safetyboost) runs just as strong as a stock TT on normal boost.

 

There is a guy in the US that ran 16 psi on a turboed (high mileage) NA engine (with 370cc injectors) and the engine went bang, but not because of detonation.

It was one of the wristpins that gave up (NA wristpins are thinner then TT pins) and as a result put a rod through the oilpan.

I was considering this myself once ie: puting n/a pistons in a TT engine but decided against it :)

thanks for all the comments lads. doesn't seem like it will be as easy as i hoped :(

 

paul c thanks for the links. gave me some idea of the cost which i think will be more than i wanted to spend.

 

if i got a tt engine from a breaker would it have everything i needed attached or would i need extra parts like intercoolers? also i think the front bumpers are different. is this true?

Lymon, I would be interested to hear/read alot more about your experiences regarding TT'ing an N/A engine. What is required, etc.

Thanks

Dude,you know what you want!! ;) :D

LMAO :)

Yes there is loads of roam after a chevy V8 conversion, but I miss the 'punch' from turbos.

David, isnt that the conversion using a TT lump, instead of TT'ing an N/A lump?

How about all the Power, weight reduction & response from a modified Nissan Vh45de V8 instead ;)

 

Im sure I've seen "Turbocharing an NA" threads somewhere, trying to find.

* TT engine

* Intercoolers

* Intercooler plumbing

* Intake plumbing

* TT radiator

* TT oil cooler and hoses

* TT A/C condenser and A/C lines

* Recirc valves or BOV's

* TT ECU

* TT EFI Harness

* TT flywheel

* TT clutch and pressure plate

* TT fuel pump

* TT front fascia

* Modify idle circuit plumbing to attach to intake hose.

* Fabricate mounts for IC plumbing, radiator, and oil cooler.

* Modify manual tranny bellhousing for larger flywheel

cheers for all the replies guys. looks like it's just going to be too hard and expensive to convert. i can now either sell mine and buy a tt or spend my money making my n/a faster and look better.

 

cheers again all.

 

alex

I am confused by Alex and Shunter having the same picture.

 

But Lymon - tell us more about putting turbos on a NA if you will?

no need for TT efi harness, you can use a boost controller, and then no need for the wastegate solenoids

 

no need for A/C or any pipework optional, and no real point

 

and you would use a TT gearbox, flywheel, to save any hassle of grindng out the inards of the bellhousing, and shiming the starter motor

 

the rest is about right, as i have just finished a full TT conversion :cool:

Just through interest.... roughly what would a TT conversion cost?

Just through interest.... roughly what would a TT conversion cost?

 

depends on what power you want, the car in question has had alot including jwt 530s 555's pace side mount intercoolers koyo rad etc etc

 

very rough idea would be £3000 for parts +labour to which depends on who's fitting and also how far you want to go with aftermarket parts

 

obviously a decent engine with good comp, and re con turbo's £1500ish

new clutch&flywheel £500ish

 

boost controller to avoid changes to EFI harness £200ish

 

gauges for boost, water, oil aftermarket £100 ish

 

everything else you could use second hand

>> tell us more about putting turbos on a NA if you will?

 

conversion is pretty straight forward..

 

parts needed are,

 

ENGINE:

-TT manifolds + new gaskets

-Turbos + wg actuators + all piping to/from turbos,

Turbos from an automatic work best on the NA engine

New tubs HIGHLY recommended...no recons or 2nd hand units.

-short type downpipes as found on stock jspec and early ukspec TT's

-TT injectors (370cc) work well, but if you're planning on running > 10psi, 555cc injectors highly recommended.

-TT IACV unit, as the NA unit is not suitable for boost applications

-TT oilfilter bracket + hoses

-Recirc valves (or BOV's)

 

COOLING:

-TT radiator + hoses, koyo radiator recommended

-TT oilcooler (larger European model recommended)

-intercoolers + all piping/hoses

 

GEARBOX:

-TT clutch + flywheel

if automatic: TT AT gearbox/flywheel/TC + wiring + ECU + extra oilcooler

 

BODY:

-TT front fascia (although slits can be cut in the NA bumper to allow flow to the intercoolers)

 

ECU:

custom chip to suit the high compression or an AEM

 

recommended, but not absolutely required:

-Electronic boostcontroller

-TT oilpan

-TT ECU + TT fuelpump + TT FPCU + wiring

-good/accurate boost, watertemp. and oil temp gauge.

-TT coolant pipes/lines behind plenum

the waterlines behind the plenum are different on the NA engine and can be modified to be able to connect the turbo coolant channels, but easier is to use the TT piping

 

If you want the keep the aircon, you will need a TT condensor + TT AC lines and have the ability to do a R12 refill (or do a R134a conversion at the same time)
