Increasing the power of the tubby is easy but you do need more fuel and a way of cooling the turbo gasses. (plus a load of other bits and bobs)
My question is can you run a bigger intercooler and a st205 chargecooler?

Running a chargecooler is a hell of a job. I asked DSA to fit a chargecooler to mine and dave was adamant that there wasn't enough money in the world to do the job.


Nearly everyone in the GT4oc has punted their chargecoolers to deuce turbo owners when they've swapped to front mounts. They cant get enough of them it seems.

Original poster, extra fuel could come via a re-map but your limits will be defined by your injectors, what age turbo do you have?

You would need some very twisty pipework to run both for probably not much gain. I would had thought you would be better off using a chargecooler and the space for the intercooler as a radiator to the chargecooler.

I thought a remap wasn't worth a toss in a Toyota? A lot of guys seem to run Apexi fuel computers???


By re-map I'm talking fit an Apexi PowerFC and get it mapped or ANOther brand standalone.

From what I've read on various sites I wouldnt let an S-AFC near my car.

Increasing the power on a Rev 3:

1) 3" exhaust plus decat turbo downpipe.
2) Manual boost controller (Grainger valve) about £20 (if you can't afford an electronic one).
3) Decent Boost gauge (Defi, Blitz etc)
4) Chargecooler can be fitted. Celica one will fit with a small rad at the front of the car (a fiat Cinquicento one will fit) otherwise a better intercooler (Greddy, Berk, ARC) and fan is fine up to about say 330bhp.
5) Apexi Power FC is a great mod. Just had one fitted and mapped - way better torque at low revs, sharper throttle response and more poke at the top end.
6) Run boost at about 1.1 bar and off you go. Should be looking at about 300bhp with well over 250lb/ft of torque.

Bear in mind the Rev 3 has 540 injectors, so doesn't need upgrading unless you fit a bigger turbo and go for over 350bhp. Rev 1 and 2s use 440 injectors I think and need changing.

also rev1 & 2 you need a special modified APEXI power Fc, the 1994 rev3+ cars plug and play are avaiable from £500.

Also Radtec do a charge cooler system as do PACE, as does PWR via THOR racing or of course you cdan use the celica charge cooler, but need to DIY the rest of the install.

My old car is currently for sale and will be a good big power base, its a rev2 with ross forged pistons, metal HG, HKS pullies, hybrid turbo etc current owner wants £3500 see sale section on IMOC

You were told rubbish then, a number of MR2's run chargecoolers these days, from a ST205 Celica or the likes of Pace. If you then add a decent filter, exhaust, bigger injectors, TD06 turbo and some sort of management for it all you can see well above 400bhp.

I see you're selling your MR2 for an RX7. I take it you've driven a few - apart from being gorgeous, what are they like compared to an MR2?

I ended up getting rid of the MR2 in march for the cheap alternative of the MX5, i decided at present i didn't want to take the risk of an RX7, i think you need to spend at least £7K going by those i saw and then have a £4K backup for engine build should it fail.

I Bought the mx5 and regretted it until i went out in a BEGI 261bhp MX5,.. i've now placed the order for that kit and will keep my mx5.
