Ok sorry, but long story, I’ll try to keep is as short as possible.
TLDR Main things down below in bold fond.
Car in question is my 1992 Volvo 960 with original b204FT engine. Engine and head are completely overhauled and “as new”. Did the timing belt this summer, timing is 100% correct.
960 Specs are:
- Original 204ft manifolds
- 3” tb (original one had way to much play on shaft which caused, leakage no real gains in change drive wise/ performance wise had the tb as a leftover from my b234f)
- TD04-16T turbo (good condition) (was before brand new, GT3071R cosworth turbine ar.72)
- Kl racing intercooler for aircon cars
- Apexi AVCR EBC
- Blabla chipped Lh 2.4
- Bti wasted spark
- New oem fuel pump (new lambda, new tps, new coolant sensors, enz enz all new, all bosch)
- Original ultrasonic cleaned injectors
- (Original) 3” MAF (not new but unobtanium)
- 2.75”dp 2.5” catback no cat
Had this car for over 12 years, been in storage several times due to other temporary cars. Neglected the car for too long because it was **** to drive. No low end torque whatsoever, was a dog until 4000 rpm then max boost kicked in with the gt3071r. M90l2 was a **** box with way to short 1st and broken 2nd and 3rd synchros. Owned several cars after storing the 960 that were so much more enjoyable to drive.
Volvo 850 t5 Auto, chipped, big dp, r manifold, fast, 450k kilometres milage, sold it at 470k (too much leakages).
Audi S4 2.7tt (stupid high low down torque, instant spool, drove like a charm, was a ****box that broke down every week ended up selling it, because no more time left to fix the thing every week.
Fiat Croma 2.4 JTD (200 hp diesel) Auto, drove like a charm, just wasn’t “my” car, very much low down torque. (Bought it dirt cheap with the intention to sell it later on with profit, which I did).
Alongside I also (still have) a 740 with an 850 2.3 t5 swap.
740 Specs are:
- M90H2 (still in mint condition don’t, know how, but guess I’m lucky)
- Chip
- 15g
- r manifolds
- 3”tb
- big ebay intercooler (with water spray like the evo’s)
- 3”exhaust no cat
This thing starts spooling at 1000 rpm, has max boost at 2000/2300 rpm ish (1.4 bar) till 5500 rpm than drop off due to 15g. Very dd able car, did this for 3 years, but has no comfort at al… no options and track tuned suspension (I’m driving 100 km a day now so not desirable)
To come back to case, I sold the Croma and want to dd the 960 again, till it’s worn down. So in about 100k or 150k kms (current is 210k km). But it has to be a nice drivable dd car which I can enjoy every day and take the high fuel consumption for granted.
Things I did to the 960 before I started driving it again.
- Ditched the GT3071r for a 16t turbo, to hopefully increase the spool time down low for more usable low end torque. This car is a dd, I don’t want to slam the throttle for it to go forward.
- AW71L with accumulator mod, to ditch the stupid m90 and because my dd is 50% stop and go traffic.
- Changed the rear diff from 3.73 to 3.91 to help with the off the line power. Car has swapped Multilink MK1
- Fiddle with the apexi to keep the wg 100% close at spool up to reach maximum spool up time boost is set at 1.2 bar AFR is o.k. (at wot 11/11.5).
Main issue:
So the thing is, when it’s up to temp 80 deg Celcius oil, it will go o.k. starts spooling at 2500 rpm max boost at 3200 rpm ish. And when the oil is over 90 deg then it reaches max boost at 3800 rpm…
The thing what I can’t understand, is that it won’t spool up early. Just no way that it will spool. The difference between the 740 t5 and this is one cylinder and 0.3 litre volume. (I know not a real comparison..), but the t5 feels like a big v8 torque wise. While the 960 is slower to 50 km/h than my girlfriends 1.5 swift automatic…
But the fact is that it’s a fresh engine with 2.0 litre and 16 valves and I would think it could do better with the relative small 16t turbo.
The 2.0 lancer EVO 8 from a friend of mine spools waaaay faster and has a bigger (I believe td05-16t) turbo.
I understand that the redblock an old engine (by design), but I want to keep the car and dd it. Now I’m seriously thinking about doing another t5 or perhaps a t6 swap. Because im sick of having no low end torque. I can’t get it to drive how I want and that’s annoying me to hell. I’m not aiming for high power, 250 300 crank hp is enough, standard is 200 hp. But I want usable power with early spool. Is this wishfull thinking? I have an AEM wideband, afrs are good but I don’t trust the AVC-r completely..
Big question, does anyone have any input on the cause, or perhaps a solution to my problem.
(Is it even possible to have early spool with a 2.0 litre?(16v)) or should I give up on trying to make it happen and swap in a t5 or t6 and call it a day (don’t care about the cost or labour, done it before I want a car which I enjoy) but I don’t want to ditch the b204ft just yet.
Any help will be greatly appreciated. anyone with a b204ft and the same problems, or no problems at all? Every feedback is appreciated.
Solutions I thought about:
- Try to ditch the avcr and fix the wg close for testing, with minding of the throttle (risky rather don’t want to do this)
- Ditching avcr and put in an mbc?
- Thought about a stand-alone management but for dd, and minor power increase I think its overkill. But if my lh is the problem then I am strongly considering it (losing the unobtainable maf is a pro).
