Hello

I took the bumper of my car at the weekend to have a measure up for making a home made FMIC kit. Now i really want to use a Intercooler I have sourced (Evo 9) and this has entry one side, exit the other. This causes a problem because getting the charge from the turbo to the entry of the intercooler on the left hand side (if looking head on at the car) means lots of awkward pipework. (going over the engine and down past where the horn normally is).

So what i was thinking is, can a 225 inlet manifold be used on a 180 engine? As they have the throttle body on the other side of the inlet manifold i would route the charge pipe as per the std route, enter the intercooler on the left, exit on the right, then up to the throttle body. I think this is what happens with aftermarket FMIC kits on 225 engines anyway.

Has anyone done this and can they let me know whats involved, or shed any light on this.

I also fitted a full set of Vibratechniks engine mounts while i had the ramps. They are so cool. Make the whole front end feel more stable and gear changes much more direct. I worthwhile change if you enjoy driving hard and fast

Kind Regards

I cant see any real problems arising from it tbh.

ive not done it though!

Thats what i thought, just not sure if their is something about the 225 inlet manifold that ment it was wildly different and could not be used.

Anyone know of a source of a 225 inlet manifold? Might as well get one and have a look.

Garry

scrappies?

worth a check, but also if its bigger, get the AFR's checked before giving it stink.

same applies with the fmic as i understand your map is close ish to the edge of the envelope?

Mike, yes will get it checked out before driving too hard. Will get Simon at F1 Brighton to check it out and map it again if needed

Just doing all i can to get the car ready for the GT2871RS before i fit it

I hope it doesnt lag like!

Shame the exhaust manifold is so crap!. a T3 or a T34 with .48 exhausing would be ideal for an Octy.

Christ they would be a bit big i would have thought.

I still want the car usable, lol.

I dont need to worry about an exhaust manifold, i can make up what ever i want. One of the perks of the job, lol.

Garry

T3 is a 270bhp turbo.. tiny

A T34 is a 330bhp turbo

I must be getting confused. I helped my mate build a 1.8 8v Turbo engine in a Coraddo G60. That had a T3 turbo, but that had over 350bhp. My mistake.

Regards

Garry

Well, T3 is very subjective lol

some T3's are quite big.

The T3 and T34 i was on about are the ones found on Cosworths

Oh i see. That makes sence

Think i will stick to the tried and tested GT2871RS turbo. Seen a few cars with them now and driven one. Drives really nice. Like Standard only faster :D. I will aim for a sensible 330bhp ish. Should be fun.

Now, back looking for a 225 inlet manifold.

Regards

Garry

330bhp is around the limit of the standard internals. i'd sacrifice power to ensure reliability.

Internals will be upgraded at the same time. Got a nice set of rods and pistons sourced. Just working some magic on a spare crank i have to play with in the workshop here. See if the design can be improved at all.

Reliability is always my number one priority

Garry

If you're going to such measures Garry, then seriously, look at making a manifold with a T3 flange.

This opens you up to being able to use LOTS of turbo's!

A T34 with .63 housing is suitable for 380bhp applications, and isnt too laggy.

Can be bought second hand for £400 too

Second hand turbos???? No way Mr. lol

Just one of those things that should not be bought second hand. How much are they new?

Kind Regards

Garry

i've had plenty of second hand turbo's.

New turbo's warranty's are not worth the paper they are written so, so why buy new?

They tend to be around £800 exchange.

Besides, the GT2871RS turbo uses a ball bearing core. Knacker this and its cheaper to replace the whole turbo that it is the core.

I've also bought plenty 2nd hand turbos in the past, never been let down yet.

*Got a pair of HKS 2350's here if you're keen *

MMMMmmmm, Worth thinking about....

Will have to research this again nearer the time me thinks.

Johnny - I ordered my LCR Splitter. Will be delivered here tomorrow so will fit it at the weekend. You can see how good your car will look when its fitted then :p

Regards

Garry

Garry, i love the way you make fitting new rods and pistons etc sound so easy.

I Will look forwards to seeing some pics/figures of the beast when its finished .

I wish i had the cash :(

Mart, i wish i had the cash to do it all now. lol, dont want to wait. Like a small child.

I do make it sound a little easy i guess. I built a few engines from time to time, and with my job an engine build is nothing to me really, just day to day routine. I should calm down a little tho. Will be sometime next summer i expect to do the build, but im a big fan of plan early, very early. Want to do it all in a weekend really, so have to make sure everything is done and ready prior to that.

First step is to get a FMIC fitted. As this can be run using my STD turbo it makes sence to do that now. Hence the requirment of a 225 inlet manifold. I wonder if they flow anymore than a 180 inlet manifold. Will stick it on the flow bench to check i think

Thanks for all the support.

Kind Regards

Garry

Best thing to do Garry is find a cheap AUQ engine and get it all built up and then it'll make a weekend swap over easy.

And it just happens one of my customers have an AUQ in stock !

And thier was me thinking they were hard to find and expensive

Go on then, how much?

Regards

Garry

There's no price set against it, but going by the system it has around 60k on it.

I can find out tomorrow for you if you like ?

Go on then. lol. I got an abundance of cylinder heads here to play with. Got one flowing little over 20% better but without increasing the ports too much so drivability is still very good.

Keep me posted. Also, can you find out if they have a 225 inlet manifold

Regards
