Im still after minimal lag with decent 330bhp from a std compression 2wd YB, it will run 803s and a 3bar MAP, what can be changed on it to improve throttle response on a std engine?
exh manifold- change to a tubular type?
inlet manifold- change to a Swedish type?
T34 exh housing-down size to a .48 from .63?
Pace rS500 type cooler or 2x 2wd Icooler welded infront will be sufficient for cooling and response?

anything recommended or should I steer clear of? Apparently at my power level and even 380-400bhp a swedish inlet will reduce throttle response? I could polish the trumpets and inlet inside to speed air flow maybe??

Dont need a .63 housing T34 for 330bhp for a start.
Barely need a .48 housing one TBH, but changing to a .48 housing will make the biggest difference my far.

Changing ex manifold for a fancy one will be a waste of cash at such low power, as would changing the inlet.
Changing to a 4x4 ex manifold may help a bit, but not loads.

I never noticed any difference going to a 500 cooler from a standard 2wd one.

All this polishing to increase airspeed thing is bollocks when you got a turbo involved.

A live map will make the car a lot better than a off the shelf chip, even on greens and std lump.

Seems to me barring changing the turbo to one thats correct for that power level, the other stuff is wasting your cash for nothing.

IMO RS500 cooler, .48 T34, 4x4 manifold if you can be arsed, 25psi on a live map with maybe a bigger midrange spike, happy days.

Spend the rest on tyres and shit.

Just to back up what has already been said .

RichardPON

Just buy my engine!

Std comp 200 block, std 4x4 head, big wing sump.

Then slap on a set of greens, T34 .48, RS500 style I/C and rag the arse off it!

justin.e

if its only 300 odd ponys you want I'd bin the t34 and go for a t3 for better responce

330 is ragging the ass off a T3 though isn't it?

Rick

Certainly is - and there is a miniscule difference in responce when on same back end.

I'd go for the reliability and lower charge temps that the T34 would give you then

RichardPON

Yep, and the T3 can easily let go running high levels of boost.......

My old one did whilst I was racing an M3 - how embarassing!

Ok then, I have a .48 T34 already, so spot on there, I already have a Pace 500style I/cooler so that may go up for sale, get £250 for it? and swap for a Pro alloy version? the 2x2wd coolers will go up for sale too
I will be running a 4x4manifold anyway due to engine mount clearance issues, so how about a tubular one? that wont have adverse effect over a std item will it, I have one of those I could use you see.
And I will be sticking with the std inlet and 2wd throttle body too then and a trip to Blackpool no doubt, it has to have dizzyless ign plumbed in cos I hated my old cars missfires on boost

RichardPON, Im still working upto your engine as I want the sump for the odd occasion I will have grip Just need to shift some parts and collect some £££

RichardPON

Std 4x4 exhaust manifold will be plenty good enough at that power.....

4x4 manifold is still bolted to my engine with brand new gaskets anyway

I'll give you a shout over the weekend and we can chat cars..........
