Heard a few bad things about the Cometic gaskets recently, although some people are still ok with them, up to you but I would be seriously considering the extra £200 for a genuine Mountune 4 layer WRC gasket!

Air 2 air injectors with vari boost control - Noooooo! Use a proper Jap "active" boost controller
8 Greens - OK......but peeps will point out that 4 big injectors is the way to go - I am starting to think that they are correct
P8 ECU - Again "quaint" old skool, depends on the above choice of injectors.
Racing loom to run coil packs and some other tricks -
BD14 ex standard Inlet cams -
9:1 compression - NO!
Vern pullys -
Cosmetic gaskets - NO! WRC only
KONI - OK
Poly bushed all around - OK
Samcos - OK(ish) there are others
Oil breather - Yes = Bailey

O YER AND IT WILL BE SET UP BY

AHMED= sound

Change the Cometic gasket for a pukka WRC 4 layer one.

Stavros

Lower the compression

BTW......We are talking T4 turbo.....yes?

I would stick with the air to air injectors and have the boost curve properly mapped to suit .

Nothing wrong with P8 and it can run big injectors (as can L8 etc - just ask Stu ).

Cam choice will make it responsive at expense of outright top end power .

Compression seems way to high and will require loads of ignition retard (and resultant excess heat), so best to lower to what Ahmed recommends .

Disabled Account

As Steve says, lower the compression!

For pump fuel and useable high boost through the rev range the comp ratio is far from ideal!

Shouldn't the WI come before the setup

And as good as your gaskets might look, they are not going to do anything for your engine

Mike,

At TOTB 3, 31 cars in the top power (4x4) class....some very fast ones, some extremely fast ones...............

1. How many with Air to Air????

2. How many with Electronic Boost Controllers????

I dont know the answer, but I will guess at:

1. 0

2. 28 (i.e. ALL of the turbo cars)

I agree with Doug

RichardPON

Doug,

Isn't that because the std Jap management systems wont integrate with stuff like air to air, where the overpriced Jap boost controllers are standalone in most cases......

Stavros

If you mean in terms of how the cars mapped, no IMO.

IMO Water Injection should only be used as a backup safety thing incase somthing totaly unexpected happens, deffo shouldnt be used as part of the setup of making the car reliable when being driven flat out, that should be taken care of by a properly specced car and good fuel and ign mapping.

rs cos

mike probably doesn't sell jap electronic boost controllers doug, thats why they are shite!!!

Disabled Account

Richard,

You may well be right, but fitting air to air hardware/software/mapping is MORE expensive than most Jap boost controllers....and LESS flexable IMO.

Disabled Account

Water Injection deffo to be used as a safeguard only.......

i.e. triggered just before peak boost when charge charge temps are getting high.

Disabled Account

LOL, but I dont think Mike has said that they are shit.

I'ts just that when you use one of the very best engine builders in the business (for YB engines) and THE best mapper, you have access a very potent combination (SCS + Ahmed). You tend to listen to what they say/reccomend, in reality you devieate from what they spec at your peril!

So I can see where Mike is coming from But I also see where he is going - and i'ts a cul-de-sac

swerv

a lot of people still use the cometic gasket with no probs at all , i understand a few people had problems but this shouldnt really put people off cometic

i really think that you have the cams the wrong way round as well

can i ask how you have come up with that spec as it seems a bit "thrown together" no offence like

Mike Rainbird

iTrader: (3)

Doug and that is your best arguement?

Now narrow that down and tell me how many of these were running fully mapped / mappable ECUs with properly mapped boost curves? . I know a few were (MoTec / Autronic).

Personally, I would prefer my ECU to have FULL control of what is going on .

PS. I can / do sell Jap style boost controllers, but would always recommend that where possible to use the ECU to contol the boost.

TIFF

Put it this way

The Cometic gasket that went on my car damaged the head and the block, there fore the head had to be completely stripped down and skimmed, the Block had to be removed and completely stripped down and also skimmed and it cost ALOT of un-nessesery money because of a faulty head gasket.

I WOULD NOT RUN THAT RISK AGAIN FOR THE SAKE OF £200 MORE ON A WRC GASKET

Just trying to advise people so they dont make the same mistake.

CozzyBrom

greddy boost controller all the way
you can set diffent boost curves for each diffent gear and it has data logger aswell
air injectors are over priced and your stuck with one boost curve unless you have a controller
as for your spec i would say old skool times have changed t4 waste of time small power band all over by 7500
money could of been spent better each to there own am not having a go

God so many repilys so quick i going so water as a safe gaurd on top end?
the boost swicth is part of the loom but it will be mapped

What were the three aspirated 4x4s? Am trying to think of a TOTB worthy aspirated 4x4 - think I've just had something slip my mind.

Disabled Account

Mike, fair point about ECU control........but IF you had driven my car before and then after the Greddy boost controller was fitted I am 100% sure you would NOT have said to me "take that off"

The BIGGEST difference was low down (at the onset of boost), responce and smoothness

Anyway, it was Harvey that told me that I should try an electronic boost controller............2 days later Simon fitted it

Brom are you using the profec A or B?

Just sold my Apexi avcr from the datsun as i figured it was a waste of time for a 3 dr (cant use the ECU dependant functions on AVCR), was gonna go for the profec B as a no frills boost controller...

Disabled Account

I know that you are asking Brom, but I use Profec B - it works very well IMO you dont need anything more complicated

Disabled Account

No, this is:

Pectel just released a new ECU.............does it have facility to map for the fantastic state-of-the-art air injectors??????????

You tell me Mike

Mike Rainbird

Doug,
Please insert the word "budget" before ECU .

rsnissan

iTrader: (9)

cheers dude was lookin for a profec I see the have a profec B II now what one do you have the B or the BII?

also i take it i can junk the AMAL valve with out the ECU spazzing out

Disabled Account

Mike .......as allways you have a good argument BUT crucially you are out numbered by those that dont...........so YOU loose

St3V3_C

The point I was making with WI was that it would not be right to bung in any old pump and jet and expect everything to be hunky-dorey...

Greddy B Spec II is the one I have - does exaclty what it says on the tin

Mike Rainbird

Doug,
If it works for you, then I am happy for you .

I will continue to use my fully mapped air-injectors though thank you .

Karl

Personally I'd disagree with C.R, cam choice and gaskets.

As for air injectors I like them, and find that if properly mapped are excellent!

Disabled Account

Karl,

Without giving too much away, would the following be OK/safe?????????
C.R. 7.4:1
BD 16's in/out
"O" ring block and YB 1260 (late Es Cos gasket)

Rick

Can u explain what u mean pls, as i am looking onto one of these. As far as i can see it's got a high/low boost curve for every gear?

Ian M500COS

9.0:1 compression + T4? .......tick.....tick.....tick

Cometic gasket on High Comp? Absolute faeces. Rhinoceros manure. Total camel excrement!

Rick

Ian M500COS

New Pectel T4 ECU will be able to control large injectors.

DaveEscos

what are they? made by rimmel!
