Hi Guys,

Can anyone tell me if this is a simple surgical job? i.e. Will a 147 GTA engine (with ECU) simply fit my 1998 3.0L GTV?

If so what work do I need to do? i.e.
1 Will it fit my engine mounts.
2 fit my cooling system.
3 Use my existing altenator, starter motor etc?
4 Exhaust manifolds (I have pre cat manifolds but undersatnd the GTA engine exhaust ports are larger but guess manifolds can be routed but will manifold bolt straight on?

Can you let me know as my head gasket has just blown and I need to do work.:(

If I can do this work I will have a set of C&B inlet and exhaust cams for a 3.0L GTV which cost me £1200 for sale to the highest bidder. They are fantastic! and transform the car with circa 30bhp gain and excellent low down torqu!

It'll be a direct fit, not the ecu though as I dont think it'll be compatible due to it being canbus with the rest of the car.

Just have your ecu mapped to use the 3.2 engine.

+1 Don't need the ECU should just plug and play, although i don't have a 3.2 from my understanding a fair few GTA drivers use the GTV manifolds to get rid of the cats so would assume you should be ok keeping all your current bits.
Chris 155 from memory has done lots of swaps in 156's between 2.5-3.0-3.2 using the standard ECU to good effect, may want to have a look on the 156.net forum!

Out of intrest what you doing with the old engine ?

You have a 98 GTV if I am correct that’s still fitted with a cable throttle but that’s not a problem but you may have to use your inlet manifold since the idle control sits on the plenum.

i have a 98 PH2 and it is fly by wire, thought it was just PH1 that were cable ?

If it is a PH2 it is close to plug and play.
Are you getting the motor with all accessories?
If so you only have to change the power-steering pump and wiring harness on the motor.
If it is without accessories all your motors bits will bolt straight onto it.

Keep the 3.2 injectors do not replace them with the 3.0 injectors.

The 3.0 management is perfectly happy with the 3.2 and 3.2 injectors and do not attempt fitting a 3.2 MAF since that will upset everything keep the 3.0 MAF

I replaced my 3.0 with a 3.2 "GTA" crate motor and it is brilliant.

I almost forgot you have to change the temp sensor as well.:lol:

Thanks all, looks like a relatively sumple fix then.:)

Oh, it is a pahse 1 but im sure its fly by wire.

Everything seems to be going wrong at the moment but that is just life I guess.

Why not fit the C&B cams to the 3.2L? I bet they're more aggressive than GTA cams. GTA Cams are only 7deg more duration on inlet and exhaust is the same as 3.0L. Probably better off selling the GTA cams and fitting the C&Bs!

I agree with the cam change and definitely enough takers on the 3.2 cams

OK so:

Keep C&B cams and seel GTA cams. This is an easy fix as it can be done when I chnage the cambelt. They should give me (with my existing ss exhaust) and extra 20bhp at least so 260bhp. The cams worked wonders on my 3.0l so this sounds good. I have a piggyback unichip so ecu can be rolling road fine tuned to extract the max.

Throttle boddies have always been a wish list item as AHM say they achieve 300bhp on a GTA engine. So with cams...should be interesting.

Two questions on the TB's
As the brakes are servo assisted: I will lose this and need to stamp on the brakes a bit harder.
Ensuring cold air feed: I have seen some OTT carbon fibre plenum but this seems overkill, how would I feed them?

With ITB’s you will have to change the management I would suggest the Carbon fiber plenum with larger throttle instead.
At least then you can keep the oe management.

Omex 600 or similar could easily run the engine with ITBs and isn't too expensive :)

If you can afford the ITBs you can afford to pay the extra for the management :lol:

Getting after market management to run with it is easy.
Living with a car with aftermarket management does have its limitations since its just not the same as oe management in all conditions.
Personally I don’t like changing from oe management unless it is a toy.

Passing MOT might be difficult too over here with ITBs too, a tad noisy, just need to find a friendly MOT centre.

I heard you may be able to run ITBs on a dastek piggyback though.
