Which Xr6T To Buy? (Merged Topic)

Recommended Posts

Hi Guys,

I'm new to the XR6 Scene, I currently own a Modified 87 Toyota Soarer, Did by myself a 1jz conversion, lots of stuff, goes fast

but takes time to get going.

I'd always like the look of the BA and FG XR6 Turbos, just I completely know nothing about them, No idea what all the differences are

and what I should go for. I'd love a XR6T for a Second Car to sit alongside my Soarer.

Money isn't that much of an issue so I'd rather get whatever is nice. Are there many major improvements over the way the FG Drives to the BA/BF?

I take it the motors are pretty much the same or is the FG More refined and quicker to drive? Or is the motor/cams/turbo all the same from BA-FG?

From research I've done if I want an Auto, I should get something with the ZF 6 Speed.

Are the FPV models much better for the price extra you pay? or would you be better off just upgrading brakes on a normal XR6T.

I'd prefer to buy something that would have a good re-sale, so which models/years should I try to avoid?

Modding Wise I take it $3500 Worth of Parts could get me an Exhaust, Intercooler, Injector Upgrade and valve springs which are a must (Or is this only for the BA/BF Non FPV?)

and be good for about 400hp at the wheels?

What's best, a off the shelf tune, or to take it to a Dyno tuner to get a few hours on the dyno to make it run to suit the exact mods I have?

Cheers.

if you want 400hp at the wheels then FG xr6t with a zf

+

cooler and pipework

Venom cat section

injectors

maybe valve springs

fuel set up for e85 and 98

DO NOT GET AN OFF THE SHELF TUNE

I am in the same boat here Not sure on a BA or BF I do know the BF has stronger rods and valve springs But im not after huge power just something nice I have been looking for a while and most BF's seems to go for a extra $5000 Are there any other major benifits of a BF?

Also BFs have an extra knock sensor and the exhaust cam is independently timed from intake from memory. Think that helped get the extra wasps (240kw to 245kw stock and 450Nm to 480Nm BA to BF)

If the car has over 75 thousand kms budget valve springs, they are very hit and miss.

I had the decision when I bought my Turbo back in 2008 whether to buy a run out BF F6 or an FG XR6T. Glad I bought the FG as I believe it's quite a bit more refined, has a smaller smaller turbo which is very responsive, redesigned exhaust manifold and intake, better fuel economy, higher centre console and gear shifter, better traction control program, just to name a few things.

From what we gather on here 06/06 is the point where BF got the strong rods so you'd want to be going for BFII to be on the safe side. BFII over BA has what was mentioned above and as I just mentioned stronger motor. It also had better valve springs (not sure if they're as strong as fg though). Also both manual and auto gearboxs in the BFII were much stronger and more capable of handling bigger power.

As for the OP if the lag of your soarer was a worry than you'd prefer the FG over any B series because the smaller turbo! Lag is virtually non-existent for a turbo car, it start pulling straight away. FG also because BA will go boom (either engine or gearbox) eventually once you put a lot of power into it. FG is a much better base to start modding and can easily push 300rwkw for under $5000 with custom tuning

^^BA mk II have the same 6 speed manual gearbox as the BF II albeit the motor is still weaker than a BF mk II.

If you want to mod your car you need to ask yourself what kind of figures you want. The BF mk II will have less down low (an E85 tune fixes this a little) because of the bigger turbo but the turbo will take you into the high 300s. The FG is the opposite. Quicker spool but if you are after more than mid 300s at the treads you will need to replace the turbo.

Also I noticed when taking an FG for a test drive the difference in front end suspension ride is night and day with the B series.

Honestly go the BA there the best mines got 330rwkw 1200 nm toque build by cv performance all the goodies but un open engine and I'll tell you they are awesome and very reliable if done correct the only other upgrade I've done is the box conversion to C4 with 3000 stall very strong and fun the things a rocket a very reliable throughout go the BA.

I came across a ba for 13000 today I checked it out Had plenum,intercooler,injectors,tune Well that's what I could see so far and apparantly has 320kw ATW's Would it be using factory valve springs I thought. The car was very clean with 104000 on the clock I thought about the gearbox after reading up and thought it could go any time soon not to mention a small oil leak around the harmonic balancer which could be old or not. yet to hear back from the owner with questions Thanks for the replys.

Mate the best thing to do is buy one like mine with all the work done to it for around 16-17k done by a professional work shop.

No more to spend if done right they are unbeatably the best for the $$$.

Thanks for the Replies.

Looks like the FG with the ZF is the go, Would a smaller turbo mean it will pull more violently and hard on kickdown? or the opposite?

I've seen that not many people reccomend changing the Dump pipe or Intercooler, does that mean they are not a bottleneck at 400hp?

Is there any gain in spool to be had with a higher flowing cooler or exhaust? I'd be thinking pushing heaps of boost through would heat up the inlet air temps and the ECU will go easy

on the timing and be slower on hotter days?

Are the factory air inlet pipes to the turbo and filter much of a restriction? I'd like to do only useful mods to my FG when I get it.

Well that's what it looks like so far But I want to varify who and where the work was done :)

Has it had the Box done as these conversions are very expensive half the purchase price of the car to get something half decent...

With the smaller turbo spool is much quicker and delivers a greater amount of torque earlier so yes it will pull harder down low when compared to a BA/BF of similar power output.

The cat is the main restriction in the exhaust at 400hp and it is part of the factory dump so if you want an easy bolt in mod a dump and cat is the go. Certainly improving flow in either the intake piping or exhaust will improve spool and reduce restriction. It is advised to change the cooler piping as the factory plastic pipes have been known to fail with higher boost. A bigger intercooler is going to make the car perform much more consistantly on hotter days so I'd advise to get one. People have made 400rwhp without one but I'd question the consistancy of their power when the ambient temps increase.

Basic required mods to get 400rwhp are listed by sexual harrassment panda in post 2 of this thread

Sweet thanks a lot for putting me in the right direction guys, Which Intercooler kit is the best, for about 400hp, something that can soak the heat up well but still flow well I know it's hard to find a good balance.

I'm not looking for cheap crap but not wanting to get something that's 1000hp rated Either. On my previous cars from experienced I've noticed a well designed Intercooler really makes a differences

in performance.

Pretty amazing how the factory exhaust and mufflers can flow well for 400hp, is it a Twin System, are they normal baffled mufflers?

I'd like to have a good Tuning solution where I can have a base map that's been tried and proven over time, and get a tuner here in Perth to fine tune that to suit my car.

I take it the CAPA Ford Flash 2 is the best out there and can it be tuned in Real time, do CAPA send you a base tune for it for the FG?

Depends if you want to cut some of the front supports out or not. If not PWR or PW stepped coolers. If you don't mind, then rapid, nizpro, plaz, PW all make good coolers

And most people use the xcal3 rather than capa box. And you don't want pre-loaded tunes, leave it to the tuner do everything from scratch. XFT in Perth seems to be the pick of the bunch over there, has some great cars come out of their shop!

If you are in Perth, there are a few good tuners to be had. The stock dump pipe on the BF and The FG is fine for 300+ KW at the tyres. The cat is the biggest issue for both cars. The stock FG mufflers are good - single 3 inch - and seem to work well. Spolit for choice for intercoolers for both cars.

Everyone say the FG turbo spools up quicker - but it is damn hard to notice IF your tuner has the larger BF unit working well - and lets face it.... on rolling starts there is not a lot in it. The Fg is certainly more refined in terms of exhauist manifold/pipe layout etc.

The FG is a more modern cabin as well. The only issue seems to be a bit of hit /miss with valve springs - the rest is pretty good. I have a BF and really happy with it. I'd take the FG however.

G'day gurus,

I'm currently looking to replace my 80 series Landcruiser DD/tow rig, as I do far more Daily driving than towing and I want something a bit more... me.

I notice a fair bit of chatter regarding the weakness of the BA box, should I be steering clear of modified examples given the load I'm going to put it under?

I'm towing my mx5 with trailer, so about 1500kgs. All of my previous cars bar the cruiser have been boosted, but I'm thinking I should go stock. Only going BA as they are at the right price ATM, FG would be awesome, but then id have less money to race with.

Thoughts?

Scotty
